Study manual

Skin complaints account for a very large share of visits to primary care worldwide and skin disease is among the leading causes of years lived with disability — and almost none of it is seen by a dermatologist. Meanwhile pressure damage, leg ulcers, diabetic foot wounds and surgical wounds are assessed, dressed and monitored by nurses, and whether they heal depends more on nursing decisions than on anybody else's. Most pressure injuries are preventable, and their occurrence is used everywhere as a measure of nursing care. Skin also reveals illness elsewhere — jaundice, pallor, a rash that does not fade under pressure, the first sign of a fatal drug reaction. And unlike most disease it is seen by everybody the person meets, which produces staring, assumed contagion and withdrawal that clinicians consistently underestimate.

1. Why This Subject Is Everywhere

Skin Problems Are Among The Commonest Reasons To Present

Skin complaints account for a very large share of visits to primary care worldwide, and skin disease is one of the leading causes of years lived with disability. Almost none of it is seen by a dermatologist; it is seen by generalists.

Wounds Are Nursing Work

Pressure damage, leg ulcers, diabetic foot wounds and surgical wounds are assessed, dressed and monitored by nurses, and whether they heal depends more on nursing decisions than on anybody else's. This is one of the clearest examples of nursing owning an outcome.

Pressure Damage Is Largely Preventable

Most pressure injuries are avoidable, they cause pain, infection and death, they extend hospital stays enormously, and their occurrence is used everywhere as a measure of nursing care quality. Prevention is repositioning, skin inspection and nutrition.

Skin Reveals Illness Elsewhere

Jaundice, cyanosis, pallor, bruising, a bleeding rash, the changes of liver and kidney disease, and the first sign of a life-threatening drug reaction all appear in skin. Looking at skin is general assessment rather than a specialty interest.

It Is Visible, And That Changes Everything

Unlike most disease, skin disease is seen by everybody the person meets, which produces staring, comment, assumed contagion, avoided touch and social withdrawal. The psychological burden of skin conditions is consistently underestimated by clinicians.

2. Skin, In Health

A Barrier That Must Stay Intact

Skin keeps water in and organisms out, and almost every skin disease and every wound is a failure of that barrier. Once it is broken, fluid is lost, infection enters, and temperature control is impaired.

Three Layers, Different Roles

A thin outer layer that is the barrier and is constantly renewed, a tougher layer beneath containing blood vessels, nerves, glands and hair roots, and a fatty layer that insulates and cushions. How deep a wound goes determines how it heals.

Sweat, Oil And Temperature

Sweating cools the body and oil keeps the surface supple and slightly acidic, which discourages organisms. Ageing, some diseases and repeated washing with harsh products remove that protection, and dry cracked skin is then vulnerable.

Sensation Protects It

Skin reports pressure, heat and pain, and that warning is what makes a person move before damage occurs. Remove the sensation, as diabetes and spinal injury do, and injury becomes silent and therefore severe.

Blood Supply Decides Healing

Skin needs blood to heal, so anything reducing flow — pressure, vascular disease, smoking, cold, swelling — slows or prevents it. Almost every chronic wound is, underneath, a blood supply problem.

3. Looking At Skin Properly

Undress The Area, In Good Light

Skin cannot be assessed through clothing, a dressing, or in dim light, and the commonest failure in this subject is simply not looking. Heels, sacrum, between toes, under breasts, in skin folds and behind ears are where things hide.

Describe What You See

Flat or raised, fluid-filled or solid, scaly or smooth, single or many, where on the body, and what shape or pattern. A description in ordinary words that another person can picture is more useful than a guessed diagnosis.

Distribution Is A Clue

Rashes on sun-exposed areas, in skin creases, on the hands and feet, following a nerve, or where something touched the skin each point in a specific direction. Where it is tells you as much as what it looks like.

Feel It, And Ask About It

Warmth, tenderness, hardness and whether it blanches under pressure are all found by touching. And asking how long, how it started, whether it itches or hurts, and what makes it worse narrows it further than looking alone.

Photograph And Measure

A wound or lesion recorded with a measurement and, where consent allows, a photograph, allows the next person to know whether it is improving. Descriptions alone consistently fail to show change over weeks.

4. Skin Of Different Colours

Redness Is Not Reliable

Inflammation and early pressure damage appear as redness in pale skin, but in darker skin they appear as a purple, darker or ashen change that is easily missed under poor light. Depending on redness means missing damage in a large share of patients.

This Causes Real Harm

Pressure injuries are detected later and at more advanced stages in people with darker skin, and that disparity is documented. It is a direct consequence of teaching and textbooks built around pale skin.

What To Look For Instead

Compare with surrounding and opposite areas, and look for a change in colour, a darker or shinier patch, and for skin that feels warmer, cooler, firmer, boggier or more painful than the skin around it. Touch and comparison do the work redness cannot.

Pigment Changes After Inflammation

In darker skin, healed inflammation frequently leaves areas darker or lighter than the surrounding skin, which can persist for months and is distressing. It is not scarring and it is worth explaining, because people assume permanent damage.

Ask The Patient What Changed

The person knows what their own skin normally looks like and can point to what is different. That question resolves more uncertainty in assessing darker skin than any description in a textbook.

5. Itch

It Is Genuinely Disabling

Persistent itch disturbs sleep, concentration and mood, and severe itch is comparable to severe pain in its effect on life. It is consistently treated as a minor complaint, which is why patients stop mentioning it.

Scratching Makes It Worse

Scratching damages the barrier, which causes more inflammation and more itch, and breaks the skin so that infection enters. Breaking that cycle — short nails, cool compresses, treating at night, covering — is most of the practical management.

Skin Disease Is Not The Only Cause

Generalised itch without a rash can come from liver disease, kidney failure, thyroid disease, iron deficiency, some cancers and many medicines. Itch with no visible cause is investigated rather than creamed.

Dryness Underlies A Great Deal

Much itch in older people and in hospital is simply dry skin, made worse by hot water, soap, frequent washing and dry air. Regular moisturising is a treatment, and it is the intervention most often left out of a care plan.

Night Is When It Is Worst

Itch intensifies at night when there is nothing to distract from it, which is why it destroys sleep and why timing treatment towards the evening helps. Asking specifically about nights finds severity that a daytime question misses.

6. Eczema

A Barrier That Leaks

Eczema is an inflamed, dry, itchy skin condition in which the barrier is defective, so the skin loses water and reacts to things that would not trouble intact skin. That is why moisturising is the foundation of treatment rather than an adjunct.

Where It Appears

In infants on the face and outer limbs, in children in the creases of elbows and knees, in adults frequently on the hands. It runs in families alongside asthma and hay fever, and flares with infection, stress, heat and irritants.

Moisturise More Than Seems Reasonable

Effective treatment involves applying moisturiser in far larger quantities and far more often than patients expect, and continuing between flares. Under-use is the single commonest reason treatment appears to fail.

Fear Of The Treatment

Steroid creams are widely and disproportionately feared, so they are under-used, applied too thinly and stopped too early, and the eczema persists. Addressing that fear directly, rather than simply prescribing again, is what changes outcomes.

Infected Eczema Looks Different

Weeping, crusting, sudden worsening, pain or small blisters suggests infection complicating eczema, which needs treating in its own right. A flare that is not responding as usual is assessed rather than escalated blindly.

7. Psoriasis

Thick Scaly Plaques

Well-defined raised patches with thick scale, classically on elbows, knees, lower back and scalp, caused by skin cells being produced far too quickly. It is long-term, it fluctuates, and it is not infectious.

More Than Skin

Psoriasis is associated with joint disease, and with raised cardiovascular risk, diabetes and depression. Asking about joint pain and attending to general health is part of managing it, which surprises patients who think of it as a skin problem.

The Social Cost Is Severe

Visible scaling on the hands, face or scalp produces assumptions of poor hygiene and contagion, and people avoid swimming, short sleeves and intimacy. The distress is frequently out of all proportion to the area affected.

Scalp And Nails Are Difficult

Scalp psoriasis is hard to treat and embarrassing, and nail involvement is painful, slow to improve and frequently ignored. Both need specific attention rather than being lumped in with the body.

Triggers Worth Knowing

Infection, stress, skin injury, some medicines and stopping oral steroids can all provoke a flare. Knowing this lets somebody anticipate rather than be ambushed.

8. Acne

Not A Trivial Condition

Acne affects most adolescents to some degree and causes measurable depression, anxiety and social withdrawal, as well as permanent scarring. Dismissing it as something they will grow out of causes lasting harm.

Blocked Follicles And Bacteria

Oil production, blocked follicles, bacteria and inflammation combine, which is why treatment addresses several of those at once. It is not caused by poor hygiene or by chocolate, and saying so removes a great deal of unwarranted blame.

Scarring Is Preventable

Deep inflamed lesions scar, and effective treatment started earlier prevents scars that cannot later be removed. Delay while waiting for it to settle has a permanent cost.

Treatment Takes Months

Improvement takes weeks to months and skin may worsen initially, so people stop after three weeks concluding it does not work. Saying the timeframe in advance is the difference between treatment working and not.

Scars And Marks Differ

Dark or red marks left after a spot fade over months and are not scars, while true scars are textural. Distinguishing them relieves considerable distress, particularly for patients with darker skin where marks are more prominent.

9. Bacterial Skin Infection

Spreading Redness And Heat

Infection in the skin and the tissue beneath produces an expanding area that is red or darker, warm, swollen and tender, usually with fever. Marking the edge allows the next person to see whether it is advancing.

Where It Gets In

A crack between toes, a cut, an insect bite, a leg ulcer, an injection site or dry fissured skin. Finding and treating the entry point prevents recurrence, and the space between the toes is the most commonly overlooked.

Swelling Makes It Recur

A chronically swollen leg is prone to repeated infection, and each infection damages the drainage further. Treating the swelling is what breaks that cycle, and it is usually neglected in favour of treating each episode.

Boils And Abscesses Need Drainage

A collection of pus does not resolve with antibiotics alone and requires drainage. A fluctuant, exquisitely tender swelling is reported for assessment rather than dressed repeatedly.

The One That Destroys Tissue

Pain wildly out of proportion to appearance, rapid spread over hours, skin discolouration or blistering, a very unwell patient. A deep spreading infection destroying tissue is a surgical emergency, and it kills quickly.

10. Fungal Infection

Warm, Moist And Covered

Fungal infection favours skin folds, feet, the groin and under breasts, producing itchy scaly patches, sometimes with a raised advancing edge. It is very common and very commonly treated as eczema, which makes it worse.

Between The Toes

Cracking, peeling and itching between the toes is the commonest fungal infection and is a major entry point for bacterial infection of the leg. In anybody with a swollen leg or diabetes, it is looked for specifically.

Nails Take Months

Fungal nail infection is slow to treat, frequently recurs, and requires months of treatment, which people abandon. Being honest about the timescale determines whether it is completed.

Thrush In Folds And Mouths

Yeast infection in skin folds, the mouth, or the nappy area is common in infants, in older people, in diabetes, on steroids and on antibiotics. Recognising the setting makes the diagnosis.

Keeping It Dry Is Half The Treatment

Drying skin folds thoroughly, particularly between toes and under breasts, changing damp clothing, and letting air reach the area prevents recurrence more reliably than any cream alone.

11. Viral Skin Conditions

Shingles Follows A Nerve

Painful blisters in a band on one side of the body, not crossing the midline, from reactivation of the chickenpox virus. Pain frequently precedes the rash by days and is mistaken for something else entirely.

Shingles Near The Eye

Involvement of the forehead, eyelid or tip of the nose risks the eye and needs urgent assessment, because sight can be lost. That single distribution rule is worth remembering exactly.

Pain That Outlasts The Rash

Nerve pain persisting for months after shingles is common, particularly in older people, is severe, and responds to specific treatments rather than to ordinary analgesia. Patients are frequently told nothing can be done.

Cold Sores And When They Matter

Recurrent blisters around the mouth are usually a nuisance, but in a newborn, in eczema, or in somebody immunosuppressed they can cause serious widespread infection. The context changes the significance completely.

Warts And Patience

Warts are viral, common, largely harmless and frequently resolve without treatment, though slowly. Treatment is for discomfort or position rather than urgency, and in immunosuppressed people they behave more stubbornly.

12. Scabies And Lice

Intense Itch, Especially At Night

Scabies is a mite burrowing in the skin, producing severe itch worse at night, with a rash between the fingers, on the wrists, around the waist and in the groin. The itch is out of proportion to the visible rash.

It Spreads Through Prolonged Contact

Household members and close contacts are treated at the same time whether or not they itch, because itching begins weeks after infestation. Treating only the person who complains guarantees it returns.

Itch Continues After Cure

Itching persists for weeks after successful treatment because it is a reaction rather than continuing infestation, and patients retreat themselves repeatedly. Explaining this prevents unnecessary treatment and real irritation of the skin.

The Crusted Form Is Different

In older, frail or immunosuppressed people scabies can appear as widespread thick crusting with little itch, carrying enormous numbers of mites and spreading readily in care settings. It is regularly diagnosed as eczema or psoriasis for months.

Head Lice Are Not About Cleanliness

Head lice spread by head-to-head contact regardless of hygiene, and the shame attached to them is entirely unwarranted. Saying so plainly to a parent is part of treating it.

13. The Rashes That Mean Danger

A Rash That Does Not Fade Under Pressure

Small red or purple spots that remain when pressed are bleeding into the skin, and with fever and illness they suggest meningococcal infection or another cause of bleeding. This is an emergency and it can appear late.

Do Not Wait For The Rash

In suspected meningococcal infection the rash appears late and sometimes not at all, so a very unwell person with fever, headache, neck stiffness or light intolerance is treated on that basis. Waiting for the rash costs lives.

Blisters And Skin Peeling Off

Widespread blistering, skin separating in sheets, and involvement of the mouth, eyes or genitals suggests a severe reaction that behaves like a burn and carries high mortality. It is a transfer-to-specialist-care emergency.

Rash With Fever And A Very Unwell Patient

Any rash accompanied by high fever, low blood pressure, confusion or rapid deterioration is treated as a sign of serious systemic illness rather than as a skin problem. The rash is a symptom of something else.

Sudden Swelling Of Face And Airway

Swelling of the lips, tongue or throat with or without a widespread raised itchy rash may be an allergic reaction threatening the airway. This is recognised immediately and treated as an emergency.

14. Skin Reactions To Medicines

Extremely Common And Easily Missed

Drug reactions are among the commonest causes of a new rash in hospital, and the responsible medicine was frequently started one to three weeks earlier rather than yesterday. A careful timeline of every new medicine is the diagnostic step.

The Warning Features

Fever, facial swelling, blistering, involvement of the mouth or eyes, extensive skin peeling, enlarged lymph nodes, or a patient who is systemically unwell. Any of these turns a rash into an emergency.

Stopping The Culprit Is The Treatment

The most important action is identifying and stopping the responsible medicine, and continuing it while treating the rash allows a severe reaction to progress. Everything else is supportive.

Recording It Properly

A drug allergy recorded with the name of the medicine and what actually happened prevents a future re-exposure that could be fatal. Recorded vaguely, or not at all, it is the beginning of the next reaction.

Not Every Rash Is Allergy

Some reactions are predictable effects rather than allergy, and labelling somebody allergic to a whole class of essential medicines unnecessarily restricts their future care. Describing what happened matters more than applying the word.

15. Skin Cancer

The Commonest Cancer There Is

Skin cancer is the most common cancer in many countries, and the great majority is caused by ultraviolet exposure accumulated over a lifetime. It is also the most visible, and therefore the most findable, cancer there is.

The Slow Local Ones

The commonest types grow slowly, rarely spread, and appear as a pearly nodule or a sore that does not heal, typically on the face, ears or scalp. They are curable, and they destroy tissue locally if left for years.

The Dangerous One

Melanoma can spread early and is the cause of most skin cancer deaths. It presents as a new or changing pigmented lesion, and it is found by noticing change rather than by recognising an appearance.

What Change Means

A mole that has grown, changed shape or colour, become uneven, itched, bled or crusted, or that simply looks different from the person's others. Change over weeks to months is the signal.

It Occurs In Darker Skin Too

Skin cancer in people with darker skin is less common but is diagnosed later and has worse outcomes, and it occurs at sites people do not check — palms, soles, under nails and in the mouth. Those sites are looked at specifically.

16. Sun, Pigment And Prevention

Damage Accumulates From Childhood

Ultraviolet damage builds over a lifetime and sunburn in childhood raises risk substantially, which is why prevention aimed at children matters most. It is also why protecting a child is about the adult's behaviour.

Shade, Clothing, Then Cream

Avoiding the strongest midday sun, covering with clothing and a hat, and using sunscreen on what remains exposed, in that order of effectiveness. Sunscreen alone, applied thinly and once, is the weakest of the three.

Outdoor Work Is The Big Exposure

People working outdoors accumulate enormous exposure and are rarely given any advice about it, while the discussion focuses on holidays. Asking what somebody does all day is the relevant question.

Darker Skin Burns Less, Not Never

More pigment gives real but incomplete protection, and both sunburn and skin cancer occur. Messaging that implies immunity means people never check their skin and never protect it.

Pigment Changes People Care About

Loss of pigment in patches, and darkening of areas after inflammation, cause significant distress, particularly where skin colour carries social weight. Dismissing them as cosmetic underestimates what they cost somebody.

17. How Wounds Heal

Four Overlapping Stages

Bleeding stops, the wound is cleaned by inflammation, new tissue is built, and the scar is remodelled over months. Knowing the stage a wound is in tells you what it needs and what is normal to see.

Inflammation Is Not Infection

A new wound is expected to be a little red, warm, swollen and tender, and that is healing rather than infection. Confusing the two produces unnecessary antibiotics, and missing genuine infection produces harm.

Moist, But Not Wet

Wounds heal faster in a moist environment and are damaged by drying out and by sitting in excessive fluid. That single principle explains most of what dressings are designed to do.

Closing By Edges Or By Filling In

A clean wound with edges brought together heals quickly with a fine scar, while an open wound must fill in from the base, which takes far longer and leaves more scar. Which one you are dealing with sets the timeframe.

Scar Strength Takes Months

A wound that looks healed at two weeks has only a fraction of its final strength and continues remodelling for a year. That is why lifting restrictions after surgery extend beyond the point the skin looks fine.

18. What Stops A Wound Healing

Poor Blood Supply Above All

Without adequate blood flow a wound cannot heal regardless of what is put on it, which is why arterial assessment in a leg ulcer comes before any dressing decision. Treating the dressing when the problem is the artery wastes months.

Nutrition, Especially Protein

Healing requires protein, calories, vitamin C and zinc, and a malnourished patient does not heal. Nutritional assessment and actually getting food into somebody is wound care, not something separate from it.

Infection And Dead Tissue

Bacteria and dead tissue in a wound consume resources and prevent new tissue forming, which is why wounds are cleaned and dead tissue removed. A wound that has stalled is examined for both.

Pressure, Movement And Moisture

Continued pressure on a wound prevents healing entirely, repeated movement disrupts new tissue, and surrounding skin macerated by fluid breaks down further. Offloading is frequently the intervention that matters most.

The Whole Patient

Diabetes, smoking, steroids, chemotherapy, anaemia, kidney disease, age and immobility all slow healing. A wound that is not healing is a reason to look at the person rather than to change the dressing again.

19. Assessing A Wound

Measure It

Length, width and depth, recorded consistently, is what shows whether a wound is improving. Without measurement, four different nurses across four weeks cannot tell a wound that is healing from one that is not.

Describe The Base

Pink and moist means new tissue; yellow and stringy means dead tissue; black means dead and dry; red and bleeding easily may mean overgrowth. What the base looks like determines what the wound needs.

The Edges And The Skin Around

Edges that are rolled, undermined or not advancing, and surrounding skin that is macerated, hard, inflamed or broken. The skin around a wound frequently reveals more about the cause than the wound itself.

Exudate, Odour And Pain

How much fluid, what colour, whether it smells, and whether pain is changing. Increasing pain and a new smell in a previously stable wound are the two most useful warnings of infection.

Photographs With Consent

A photograph taken with permission, in consistent light, with a measure visible, is worth pages of description for showing change. It also protects the patient, because deterioration cannot be argued about.

20. Cleaning And Dressing

Clean Enough, Not Sterile

Most chronic wounds are cleaned with clean warm water or saline, and antiseptics used routinely can damage healing tissue. The purpose is removing debris and excess bacteria, not sterilising something that cannot be sterile.

The Dressing Matches The Wound

A wet wound needs something absorbent, a dry wound needs moisture added, a cavity needs filling, and fragile surrounding skin needs a gentle adhesive. There is no single best dressing, only a best match.

Changing It Too Often Harms

Every dressing change cools the wound, disturbs new tissue and hurts, so dressings are left as long as they are working rather than changed by routine. Frequent unnecessary changes measurably delay healing.

Pain At Dressing Changes

Dressing changes are among the most painful things done to patients, and analgesia timed in advance, gentle removal, soaking adherent dressings and letting the patient pause are what make them bearable. Rushing is not kindness.

The Person Does Most Of It

Most wound care happens at home, done by the patient or a relative, so what they were shown, whether they were watched doing it, and whether they have the supplies decides the outcome.

21. When A Wound Is Infected

The Signs In A Chronic Wound

Increasing pain, more fluid, new smell, fragile bleeding tissue, breakdown of healing tissue, and a wound that was improving and has stopped. In chronic wounds these matter more than redness and warmth.

Colonised Is Not Infected

All chronic wounds contain bacteria, and swabbing every wound and treating every result produces resistance without benefit. Wounds are swabbed when there is clinical reason, and the patient is treated rather than the swab.

Spreading Infection Is Different

Redness extending beyond the wound, fever, feeling unwell, or rapidly increasing pain means infection has spread into the surrounding tissue and needs systemic treatment promptly. That distinction changes the urgency completely.

Bone Underneath

A deep wound, particularly on a foot, that probes to bone or has persisted for months may involve bone infection, which needs prolonged treatment and imaging. It is regularly treated as a skin wound for a year.

Antibiotic Resistance Is Made Here

Chronic wounds are where a great deal of unnecessary antibiotic prescribing happens, and every unnecessary course makes the next infection harder to treat. Declining to swab without reason is good practice rather than laziness.

22. Pressure Damage, And Why It Happens

Pressure Cuts Off Blood

Sustained pressure between a bone and a surface squeezes vessels shut, and tissue deprived of blood dies. It happens over hours, it happens deep before it shows on the surface, and it happens to anybody who cannot move.

Shear And Moisture Make It Worse

Dragging a patient up a bed shears tissue layers against each other, and skin that is damp from sweat, urine or wound fluid breaks down at much lower pressures. Handling technique and continence care are therefore prevention.

Who Is At Risk

Anybody immobile, with reduced sensation, poorly nourished, incontinent, very thin or very unwell, or with a device pressing on them. Most inpatients have at least one risk factor and the assessment exists to find them.

The Heel And The Sacrum

Heels and the sacrum account for most pressure injuries, and heels are particularly vulnerable because there is almost no tissue over the bone. Offloading heels completely is more effective than any dressing.

Devices Cause It Too

Oxygen tubing behind ears, masks on the bridge of the nose, catheters, plaster casts, splints and monitoring probes all cause pressure damage in places nobody inspects. Looking under every device is part of the round.

23. Preventing Pressure Damage

Repositioning Is The Core

Changing position regularly, at intervals matched to the individual's risk, is what prevents the majority of pressure damage. It is also the intervention most often recorded as done when it was not.

Inspection At Every Opportunity

Skin over bony points looked at, not asked about, every time the patient is repositioned or washed. Damage found at the stage of a colour change is reversible; damage found as an open wound is not.

Surfaces Help, They Do Not Replace

Specialist mattresses and cushions reduce risk and do not remove the need to reposition, and a patient on an expensive mattress who is not turned still develops pressure damage. The equipment is an addition.

Nutrition And Hydration

A malnourished, dehydrated patient develops pressure damage more readily and heals it more slowly, so getting food and fluid into them is prevention. The dietitian referral is a pressure care intervention.

Sitting Is High Risk Too

Sitting concentrates pressure on a small area and is frequently overlooked because it is not lying in bed. Long periods in a chair, particularly slumped, cause serious damage and need their own repositioning plan.

24. Leg Ulcers

Mostly A Vein Problem

Most leg ulcers result from veins failing to return blood adequately, producing swelling, skin changes and ulceration typically around the ankle. It is a circulation problem that presents as a wound.

Compression Is The Treatment

Properly applied compression heals most venous ulcers and is what prevents recurrence, and dressings alone largely do not. Patients find compression uncomfortable and stop, so explaining why it is the treatment matters.

Check The Arteries First

Compression applied to a leg with poor arterial supply can cause tissue death, which is why arterial assessment comes before compression, always. This is the single most important safety rule in the chapter.

Arterial Ulcers Look And Feel Different

Ulcers from poor arterial supply are typically painful, on the foot or toes, with a pale or dark base, in a cool leg with weak pulses, and pain is worse when the leg is raised. That reversal of the pain pattern is the clue.

They Recur Without Maintenance

A healed venous ulcer recurs in a large proportion of people unless compression is continued indefinitely, and that is frequently not explained. Follow-up and hosiery are the difference between healing once and staying healed.

25. The Diabetic Foot

Numbness Plus Poor Circulation

Nerve damage removes the warning of injury and vascular disease prevents healing, so a minor wound becomes an ulcer and an ulcer can lead to amputation. Both problems are usually present together.

A Small Wound Is An Emergency

In a person with diabetes, a foot ulcer is urgent rather than routine, because infection spreads fast in poorly supplied tissue and bone involvement follows. Delay of weeks is measured in toes.

They Walk On It Because It Does Not Hurt

A person who cannot feel the wound keeps weight on it, which is why offloading — special footwear, a cast, crutches, bed rest — is central and why advice to rest is insufficient on its own.

Look At Every Foot, Every Time

Between the toes, the heel, the sole, under calluses and around the nails, at every contact. This is one of the highest-value examinations in the whole of nursing, and it takes under a minute.

Prevention Is Cheap And Rarely Done

Daily inspection, well-fitting shoes, never walking barefoot, checking inside shoes, prompt attention to any break, and professional nail care. Teaching this properly prevents more amputations than any treatment cures.

26. Surgical Wounds

Most Heal Uneventfully

A closed surgical wound is usually dressed briefly and then left alone, and interfering with it more than necessary introduces infection. Knowing what normal looks like prevents unnecessary intervention.

The Signs Of Infection After Surgery

Increasing pain after the first days, spreading redness, discharge, fever, or a wound that opens. Pain that is improving and then worsens is the most useful single warning.

A Wound That Comes Apart

A surgical wound separating, particularly an abdominal one, is a serious complication. A sudden discharge of pink fluid from an abdominal wound frequently precedes it and is reported immediately rather than dressed.

Drains And Sutures

Knowing what a drain is for, how much it should produce, and when sutures or clips are due out prevents both premature and forgotten removal. Sutures left in too long cause infection and scarring.

What The Patient Takes Home

When to shower, what normal looks like, what to report, when sutures come out, and who to contact. Given verbally at a busy discharge, none of it is retained, which is why it is written.

27. Burns

Cool It, Early And Long

Cooling a burn with running water for a substantial period immediately after injury reduces its depth and improves the outcome, and it is effective even somewhat delayed. Ice is not used, because it causes further damage.

Nothing Else On It

Toothpaste, oil, butter, ash and traditional applications cause infection and make assessment impossible. Saying clearly what not to apply is as important as saying what to do, and it must be said without shaming anybody.

Depth Determines Everything

Superficial burns are painful, red and heal quickly; deeper ones blister; the deepest are white or charred and paradoxically painless because nerves are destroyed. A painless burn is a deep one, which is counterintuitive and important.

Area Determines Fluid Loss

Extensive burns lose enormous volumes of fluid and require calculated replacement, and under-resuscitation kills. Estimating the area affected is therefore an urgent early assessment rather than a documentation exercise.

The Ones That Need Specialist Care

Burns to the face, hands, feet, genitals or across joints, burns encircling a limb, inhalation injury, electrical and chemical burns, and burns in children or older people. Recognising these and transferring early changes outcomes.

28. Scars, And What They Cost

Scars Tighten And Restrict

A scar crossing a joint or the neck contracts as it matures and can restrict movement permanently, which is why positioning, stretching and pressure therapy during healing are treatment rather than cosmetic care.

Overgrown Scars

Some scars grow beyond the original wound, becoming raised, itchy and painful, and this occurs more commonly in darker skin. It is not a complication of poor care and patients frequently believe it is.

They Are Numb, Tight And Strange

Scarred skin has altered sensation, does not sweat, burns easily and feels foreign to the person. Explaining that these are permanent features rather than problems to be fixed is more useful than reassurance.

What They Mean To The Person

A visible scar carries the story of a burn, an operation, self-harm or violence, and being asked about it repeatedly is exhausting. Not asking, unless it is clinically relevant, is a form of care.

Long-Term Follow-Up Is Thin

People with significant scarring are discharged with itch, tightness, sun sensitivity and distress unaddressed, because the wound has healed. The wound healing is not the end of the injury.

29. Stomas And Skin Around Devices

The Skin Is The Problem, Not The Stoma

Most stoma difficulty is skin breakdown around it from leakage, and once the skin is broken the appliance sticks less, which causes more leakage. Breaking that cycle early is the whole of the management.

Fit Is Everything

An opening cut too large exposes skin to output and one cut too small constricts the stoma, and the size changes over the weeks after surgery. Re-measuring rather than reusing the same template prevents most problems.

Output Tells You Things

Volume, consistency and colour indicate hydration, obstruction and how much of the bowel is working. A high-output stoma causes dehydration and salt loss that is regularly missed.

Around Every Tube And Device

Skin around feeding tubes, drains, catheters, tracheostomies and cannulae breaks down, gets infected and is rarely inspected because attention is on the device. Looking at the skin, not just the device, is the discipline.

Adhesive Damage

Removing dressings and appliances roughly strips skin, particularly in older people and children, and repeated stripping creates the wound you were trying to prevent. Gentle removal and skin protection are genuine techniques.

30. Smell, Shame And Being Seen

Odour Isolates People

A malodorous wound causes people to stop visiting, to eat less, and to withdraw entirely, and patients apologise for it constantly. Managing odour is not cosmetic; it determines whether somebody still has a social life.

Visible Disease Attracts Comment

People with visible skin disease are stared at, questioned, avoided and assumed to be contagious, including by healthcare staff. Touching a patient's skin without hesitation communicates something that no reassurance does.

Assumed Contagion And Assumed Blame

Skin conditions are widely assumed to result from poor hygiene, and patients arrive already ashamed. Saying explicitly that this is not caused by anything they did is frequently the most useful sentence in the consultation.

Undressing Is An Intrusion

Examining skin requires exposing the body, sometimes repeatedly, to different people. Privacy, explanation, exposing only what is needed and covering promptly are not courtesies but the conditions on which somebody consents.

Ask What It Stops Them Doing

Not how itchy it is out of ten, but whether they still swim, wear short sleeves, sleep, work or see people. That question reveals the actual severity of a skin condition, and it is almost never asked.

31. Being Examined On This

What Papers Ask

Pressure damage prevention and staging, the non-blanching rash, compression only after arterial assessment, the diabetic foot, burn first aid, and recognising a severe drug reaction. Pressure care appears in every paper.

Traps That Recur

Relying on redness to detect early pressure damage in darker skin; applying compression without arterial assessment; treating a chronic wound with antibiotics on the basis of a swab; waiting for the rash in suspected meningococcal illness; treating a fungal infection as eczema; applying ice or butter to a burn.

The Expected Shape Of An Answer

Look at the skin, in good light, undressed. Reposition and inspect. Assess arteries before compressing. A foot ulcer in diabetes is urgent. Cool a burn with running water. Stop the suspected medicine.

Carrying It Into Practice

Look under every device. Look between the toes. Measure the wound. Mark the edge of spreading redness. Time the analgesia before the dressing change. Ask what the condition stops them doing.

The Habit Worth Keeping

In this subject almost every serious failure begins with not having looked. Nothing in these chapters substitutes for uncovering the skin, in good light, and comparing it with what was there yesterday.

What the exams ask

What this manual leaves out

Written from

Honest limits

Written in plain sentences on purpose. Nursing is studied in a second language by a large share of the students who will read this, and a sentence that has to be decoded twice is a sentence that teaches less.

These are the twelve questions written with this SUNYRA nursing manual, to check what it teaches. They are not past papers and were not written to any one examination's pattern; an examination tag means only that the examination's published blueprint covers this subject. Difficulty was not graded in the source, so every question is marked medium.
