Nursing · Adult clinical nursing
Every catastrophe here was preceded by a small finding somebody wrote down and nobody acted on
In the exams: NORCET: Mains — nursing practice, case-scenario based (100 questions); NCLEX-RN: Physiological Integrity (43–67%); Saudi Nursing Licensure Examination: Critical and emergency care (Core)
Most patients who arrive in intensive care spent hours deteriorating on an ordinary ward, with abnormal observations recorded and not acted upon — which means the skills in this manual are needed most by the nurse who is not in intensive care. Critically ill patients are also nursed in emergency departments, recovery areas, high dependency units, on general wards while waiting for a bed, and in countries with no intensive care at all: the principles travel even where the equipment does not. And in critical illness the observations, the trends, the response to treatment and the moment something changes are held by one nurse at the bedside continuously. No monitor interprets anything. Survival is also not the only outcome — people who live through this carry weakness, memory problems and psychological injury for years, so how somebody is sedated, moved, spoken to and allowed to sleep shapes the life they get back.
Most patients who arrive in intensive care spent hours deteriorating on an ordinary ward, with abnormal observations recorded and not acted upon. The skills in this manual are needed most by the nurse who is not in intensive care.
In critical illness the observations, the trends, the response to treatment and the moment something changes are held by one nurse at the bedside continuously. No monitor interprets; that is done by a person.
A respiratory rate of twenty-four, a slightly reduced urine output, mild confusion, a patient who says they feel dreadful. Cardiac arrest in hospital is usually preceded by hours of such findings, which makes them the whole subject.
Critically ill patients are nursed in emergency departments, recovery areas, high dependency units, general wards while waiting for a bed, and in countries with no intensive care at all. The principles travel; the equipment does not.
People who survive intensive care frequently carry physical weakness, memory problems and psychological injury for years. That means how somebody is nursed — sedation, mobility, sleep, communication — shapes the life they get back.
Critical illness is the failure of one organ system dragging others with it: lungs failing starve the tissues, a failing circulation injures the kidneys, and a failing liver disturbs clotting and consciousness. Almost nothing stays isolated.
Tissues need oxygen delivered, which requires adequate oxygen in the blood, enough red cells to carry it, a pump to move it and vessels to distribute it. Almost every intervention in critical care is aimed at one of those four.
Ventilators, filters and circulatory drugs do not cure anything; they hold a person alive while the underlying problem is treated or resolves. That distinction matters enormously in conversations with families.
A fit young person compensates for a long time and then fails suddenly, while a frail person with no reserve fails early. The same illness in those two people is a different clinical situation.
Sepsis, shock, airway obstruction and raised pressure in the skull all cause damage that accumulates by the minute. Recognition speed, more than the sophistication of what follows, determines the outcome.
Respiratory rate is the earliest, most sensitive and most neglected indicator of deterioration, and it is the one most often estimated or copied forward. Counting it properly for a full period finds illness nothing else shows.
A young or previously fit patient maintains blood pressure by constricting vessels and speeding the heart until they cannot, and then it falls abruptly. Waiting for a low blood pressure means waiting until compensation has failed.
Falling urine output reflects reduced blood flow to the kidneys and usually precedes other measurable changes. It requires somebody to total it accurately rather than record the individual volumes.
New confusion, agitation or drowsiness in an acutely unwell patient reflects the brain being poorly perfused, poisoned by the illness or short of oxygen. Treating it as a behavioural issue rather than a physiological one loses time.
A patient who says they feel terrible, or a relative who says this is not how they normally are, is reporting data. Both have detected deterioration earlier than the chart in documented cases.
A blocked airway kills within minutes and makes every other intervention pointless. It is assessed first, every time, in every patient, regardless of what the referral said the problem was.
Noisy breathing, snoring, gurgling, stridor, see-saw movement of chest and abdomen, and use of neck muscles. A completely obstructed airway is silent, which is why a patient who has gone quiet is more alarming rather than less.
Position, head tilt and chin lift, suction, removal of anything visible, and an airway adjunct. These are immediately available to any nurse and they resolve a large proportion of obstructions.
A patient who cannot maintain or protect their airway needs it secured, and the classic reason is a falling conscious level from any cause. That assessment does not wait for a doctor to be free.
Facial injury, burns to the face or airway, neck swelling, previous radiotherapy, obesity and bleeding into the mouth all predict difficulty. Recognising them early means the right people and equipment arrive before the crisis.
Failing to get oxygen in, and failing to clear carbon dioxide out, are different failures with different causes and different treatments. A patient can have either, or both, and conflating them leads to the wrong intervention.
Oxygen is prescribed to a target range rather than given at maximum, because too little starves tissues and too much is harmful in certain patients. The target is individual and is written down.
In some people with long-standing lung disease, high oxygen concentrations reduce their drive to breathe and cause carbon dioxide to rise dangerously. They need controlled oxygen and close monitoring rather than being deprived of it.
A saturation monitor is unreliable with poor circulation, cold hands, movement, nail varnish and in certain poisonings, and it says nothing about carbon dioxide. A normal reading in a patient who looks terrible is not reassurance.
Delivering oxygen under pressure through a mask or nasal device supports breathing without a tube, and it can avoid intubation entirely in the right patient. It requires close monitoring, because failure needs recognising quickly.
A ventilator pushes gas into the lungs, which is the reverse of normal breathing where the chest draws air in. That reversal is why ventilation reduces the return of blood to the heart and can lower blood pressure.
Ventilation may take over entirely or support the patient's own efforts, and the mode chosen reflects how much they can do. Understanding which is being used explains what the alarms mean.
Large volumes and high pressures damage the lungs they are treating, which is why modern practice uses small volumes and accepts imperfect numbers. Gentler ventilation saves lives, and it looks worse on the monitor.
High pressure usually means an obstruction, secretions, biting, coughing or a stiffening lung. Low pressure usually means a disconnection or a leak. Learning that distinction is the most practical knowledge in this chapter.
Distress, coughing and asynchrony have causes — pain, a blocked tube, secretions, anxiety, a collapsed lung, a wrong setting. Sedating without looking for the cause treats the alarm rather than the patient.
Prolonged ventilation causes pneumonia, muscle wasting, delirium and dependence, so the aim is the shortest duration possible. Daily assessment of readiness to breathe alone is one of the highest-value routines in intensive care.
Deep sedation prevents the assessment of breathing and of the brain, and lighter sedation shortens ventilation and reduces delirium. Nursing management of sedation directly determines how long somebody is on a machine.
Allowing a patient to breathe with minimal support for a period tests whether they can manage, and the nurse's observation of their effort, rate, comfort and anxiety is the assessment. Numbers alone do not decide it.
Swelling of the airway, weak cough, difficulty swallowing, secretions and exhaustion all appear after extubation, and a proportion of patients need the tube back. Close observation in the hours afterwards is not optional.
A tube in the throat for days impairs swallowing, so food and fluid can enter the lungs after extubation even in an alert patient. Assessment before eating prevents a pneumonia that otherwise follows.
A tube placed directly into the windpipe is used for long-term ventilation, for airway obstruction above it, or where secretions cannot be cleared. It is more comfortable, allows speech in some cases, and eases weaning.
A blocked or displaced tracheostomy is a life-threatening airway emergency, and the signs are distress, poor air movement, high ventilator pressures and falling oxygen. Every bedside needs the equipment to manage it immediately.
Suction removes secretions that the patient cannot clear, and it also causes hypoxia, trauma, coughing and raised pressure in the skull. It is done when needed on assessment, not on a schedule.
Air bypassing the nose is dry and cold, which thickens secretions and blocks the tube. Humidification is what prevents that, and its failure is the usual cause of a sudden blockage.
A person with a tracheostomy frequently cannot make a sound and is therefore left out of every conversation about them. Providing a means to communicate is a clinical priority, not a nicety.
Shock is inadequate delivery of oxygen to tissues, whatever the blood pressure reads. That definition is what allows somebody with a normal pressure and cold hands, high lactate and no urine to be recognised as shocked.
Not enough volume, a pump that has failed, vessels that have dilated too widely, or something obstructing flow. The treatment differs completely between them, which is why identifying the mechanism comes before giving fluid.
Blood pressure is the product of flow and resistance, so a normal figure can hide dangerously low flow with maximal vessel constriction. Perfusion signs — skin, urine, consciousness, lactate — describe what pressure cannot.
Cool, pale, mottled peripheries with a long capillary refill suggests constricted vessels and low flow; warm, flushed peripheries with a low pressure suggests dilated vessels as in sepsis. This is free information from touching a patient.
A raised blood lactate indicates tissues producing energy without enough oxygen, and a falling lactate with treatment is one of the better signs that it is working. A rising one in a normal-looking patient is a warning.
Fluid given to somebody who needs it saves life, and given to somebody who does not it causes swollen lungs, poor gas exchange, delayed bowel function and worse outcomes. It requires the same care as any prescription.
History of loss, thirst, dry mouth, skin turgor, jugular veins, blood pressure changes on standing or with the ventilator, urine concentration and response to a small test volume. No single sign answers it.
Fluid given as a measured amount with reassessment afterwards distinguishes the patient who responds from the one who does not, and stops the escalating cycle of pouring fluid into somebody who is not improving.
Fluid balance is the clinical evidence in critical illness and it is frequently the least reliable document in the notes — drinks not recorded, flushes ignored, totals never added. An accurate chart with a daily weight is worth more than most monitoring.
Different fluids distribute differently and shift salts in different ways, and giving large volumes of any single fluid disturbs the blood's chemistry. That is why electrolytes are checked repeatedly during resuscitation.
Some agents constrict vessels to raise pressure and others make the heart contract more forcefully, and the choice depends on the mechanism of shock. Giving a vessel constrictor to a patient who is simply empty is harmful.
These agents damage tissue if they leak from a peripheral vein and need continuous blood pressure monitoring and precise delivery. That is why they are used in high-observation areas rather than on ordinary wards.
A brief interruption — a changed syringe, a blocked line, a flushed lumen — can cause the blood pressure to collapse within a minute. Planning changeovers and protecting the line is core nursing work here.
Vessel constrictors used to mask inadequate volume raise the pressure reading while flow to organs continues to fall. That is one of the recognised ways to produce kidney failure while the monitor looks better.
Reducing these agents is done gradually with close observation, and the ability to come off them is a genuine marker of recovery. Rapid reduction because a target was reached causes avoidable instability.
A single reading describes a moment; the direction of travel over hours describes the illness. Almost every important decision in critical care is made on a trend, which is why the chart matters more than the monitor.
Artefact from movement, a damped arterial line, a wrongly sized cuff, a probe on a cold finger, a transducer at the wrong height. Before acting on an alarming number, the nurse establishes whether it is real.
A patient who is alert, warm, breathing comfortably and passing urine is not in the state their frightening monitor suggests, and a patient who looks dreadful with normal numbers is still in trouble. The patient outranks the screen.
Alarm limits set so wide that they never sound, or so tight that they sound constantly, both produce a unit where nobody responds. Setting them appropriately for this patient is a safety intervention.
Arterial and central lines give better information and cause infection, bleeding, clots and injury. Every day one stays in is a decision, and the question of whether it is still needed is asked daily.
Is the patient acidic or alkaline, is it from the breathing or from the metabolism, is the other system compensating, and is oxygenation adequate. Answering them in that order makes almost any gas interpretable.
Carbon dioxide rises when a patient is not moving enough air and falls when they are breathing hard. A rising level in a tiring patient means they are failing, and it is a reason to act rather than to repeat the test.
Acid produced by poor perfusion, kidney failure, diabetes or poisoning shows as a metabolic acid state, and the body tries to compensate by breathing faster. That is why a fast respiratory rate can be the clue to a metabolic disaster.
A patient who has been breathing hard to compensate may show near-normal figures immediately before exhausting and collapsing. The reassuring gas in a visibly tiring patient is the most dangerous result in this chapter.
Air in the syringe, delay before analysis, a venous sample labelled as arterial, or the wrong patient's details produce a confidently wrong answer that will be acted on. Handling is part of the test.
Sepsis is the body's response to infection damaging its own organs, and it is one of the leading causes of death worldwide. It is not simply a severe infection; it is a systemic derangement.
Every hour of delay in treating sepsis increases mortality, and the single biggest determinant of outcome is how quickly somebody recognised it. That recognition is almost always made by a nurse.
Fever or a low temperature, a fast pulse, a fast respiratory rate, low blood pressure, reduced urine output, confusion, mottled skin, and a patient who feels dreadful. No single sign is specific, which is why the combination matters.
Oxygen, blood cultures, antibiotics, fluids, lactate, and measuring urine output — with escalation to somebody senior. The nurse's contribution is recognising it, escalating loudly, and not letting the antibiotics wait for a bed or a scan.
Older people may present with confusion and no fever, people on steroids or chemotherapy with almost no signs, and newborns with poor feeding and low temperature. Expecting the textbook picture is how these are missed.
Most acute kidney injury in critical illness is caused by inadequate blood flow, made worse by drugs that damage the kidney and by obstruction. Restoring perfusion and removing the insult is the treatment.
A falling hourly output is one of the earliest signs of inadequate perfusion anywhere in the body, which makes accurate measurement one of the highest-value nursing observations in critical care.
Failing kidneys retain potassium, and a high level disturbs the heart's rhythm and can stop it. That is why it is measured urgently and why the result is chased rather than waited for.
Many medicines are cleared by the kidneys and accumulate to toxic levels when they fail, and several actively worsen the injury. A medicine review is part of managing kidney failure rather than something separate.
Many patients recover kidney function, some are left with lasting impairment, and having had acute kidney injury raises the long-term risk of kidney disease. That follow-up is frequently never arranged.
Blood is passed through a filter to remove waste, excess fluid and potassium. In critical illness it is usually done continuously and gently, because rapid removal destabilises an already unstable circulation.
Keeping blood flowing without clotting, managing access, balancing fluid removal against blood pressure, and replacing what is removed. A circuit that keeps clotting is a problem to be solved rather than endured.
The amount removed each hour is a prescription, and getting it wrong drops the blood pressure or leaves the patient overloaded. Accurate hourly accounting is the entire safety mechanism.
Filtration removes medicines, electrolytes, vitamins and heat along with waste, so doses are adjusted, salts replaced and the patient kept warm. Forgetting this is a recognised source of harm.
A large line into a central vein is the patient's lifeline for this treatment, and infection or clotting in it costs them the therapy. It is handled with the same care as any central access, and not used casually.
Deep sedation lengthens ventilation, increases delirium, weakens muscles and worsens long-term outcomes, while lighter sedation with a patient who can respond does the opposite. This reversal of older practice is well established.
Sedation is assessed with a scale at intervals and the infusion adjusted to a target agreed for that patient. Without that, sedation drifts steadily deeper because nobody is measuring.
Most ventilated patients develop delirium, it is associated with longer stays, more deaths and lasting cognitive impairment, and it is frequently not recognised because the quiet withdrawn form does not cause trouble.
Daylight, night-time quiet and darkness, glasses and hearing aids, familiar voices, orientation, early mobility, pain control, and getting them off sedation. Almost nothing on that list is prescribed.
Noise, light, observations, alarms and interventions fragment sleep in intensive care, and that contributes directly to delirium. Clustering care, dimming lights and protecting a period of quiet is genuine treatment.
Swelling or bleeding inside a rigid skull raises the pressure until blood can no longer be pushed in, and the brain is damaged. Everything in head injury care follows from that single mechanical fact.
A falling conscious level, a worsening headache, vomiting, a slowing pulse with rising blood pressure, and a pupil becoming large and unreactive. A deteriorating conscious level is the earliest and most important of these.
Head position, avoiding anything that raises pressure in the chest or abdomen, avoiding coughing and straining, controlling fever, preventing low oxygen and low blood pressure, and careful suction. Each has a measurable effect on pressure.
A single episode of low blood pressure or low oxygen substantially worsens the outcome of a head injury, because the injured brain has no reserve. Preventing those is more important than almost any other intervention.
Conscious level is assessed the same way by each nurse and each shift, because the value of the score lies entirely in comparison. An inconsistently assessed patient has no usable trend.
Ventilated, sedated and unconscious patients experience pain from tubes, lines, wounds, suction, turning and simply lying still. Absence of complaint is not absence of pain, and under-treatment here is the norm rather than the exception.
Grimacing, frowning, a rigid or resistant body, a rising pulse and blood pressure, fighting the ventilator, tears. Behavioural pain assessment tools exist because these signs are real and interpretable.
A distressed patient is frequently in pain rather than under-sedated, and sedating them without analgesia paralyses the expression of pain without treating it. Treating pain first is both more humane and more effective.
Turning, suction, dressing changes and line insertion hurt, and giving analgesia in time to be working is a nursing decision. Doing them without it is remembered by patients who were more aware than anybody realised.
Survivors describe pain, suction, thirst and being unable to communicate with distressing clarity, sometimes years later. That testimony is the reason this chapter exists.
Feeding into the gut early in critical illness maintains the gut lining, reduces infection and improves outcomes compared with delay or with feeding into a vein. Where the gut works, it is used.
Feed stopped for procedures, for scans, for position changes and for displaced tubes means many patients receive far less than intended. Totalling what actually went in, rather than what was prescribed, reveals the problem.
A feeding tube in the lung delivers feed into the airway with catastrophic consequences, which is why position is confirmed before every use by the prescribed method rather than by listening or assuming.
Constipation from immobility and analgesia, and diarrhoea from feed, antibiotics and infection, are both common and both consequential. Neither is a minor matter in a patient who cannot get to a toilet.
Critically ill patients lose muscle rapidly even when fed, which is why early movement matters alongside nutrition. Feeding alone does not preserve the ability to stand.
Critically ill patients are immunosuppressed by their illness, have tubes breaching every barrier, and are surrounded by resistant organisms. Infection acquired in intensive care is common, lethal and substantially preventable.
Hand hygiene remains the single most effective measure, and compliance falls exactly when workload rises, which is when patients are most vulnerable. This is unglamorous and it is the whole of the argument.
Positioning the patient partly upright, mouth care, avoiding unnecessary sedation, and minimising ventilation duration reduce it. Each element is nursing work and together they measurably change outcomes.
Sterile insertion, daily review of necessity, careful hub cleaning and not using a line unnecessarily. The most effective single measure is removing the line when it is no longer needed.
Isolation protects other patients and costs the isolated one contact, observation and sleep. Balancing that, rather than applying it thoughtlessly, is part of doing it well.
Each cannula, catheter, drain and tube bypasses a barrier the body built. That framing makes the daily question — is this still needed — the most important one asked on a ward round.
A patient may have a dozen tubes, and a nurse who cannot say what each is for cannot recognise when one has failed, been misplaced, or should have gone. Labelling and documenting them is basic safety.
Connecting a feed to an intravenous line, or giving an intravenous drug into the spine, has killed patients. Design features and deliberate checking exist because these confusions are made by competent people under pressure.
A displaced airway, feeding tube, drain or central line can be immediately life-threatening, and displacement usually happens during moving, turning or transfer. A person allocated to each tube during a move prevents it.
Recording the depth of a tube and the mark at the lip or nostril is what allows a nurse to detect that it has moved. Without it, migration is invisible until something goes wrong.
An immobile, poorly perfused, often overloaded patient on vessel-constricting drugs develops pressure damage quickly. Repositioning, offloading heels, and inspecting under every device is the prevention.
Turning and sitting a patient up improves ventilation of dependent lung, and lying prone for periods improves oxygenation substantially in severe lung failure. Position is therefore treatment, not comfort.
Turning a ventilated patient face down improves oxygenation and risks displaced tubes, lines and pressure injuries to the face, chest and knees. It requires a planned team with an allocated role each.
Sitting, standing and stepping, even while ventilated, reduces weakness, delirium and length of stay. It looks alarming and the evidence supporting it is strong.
Limbs left in comfortable positions contract, and a contracture can permanently prevent walking or dressing. Passive movement and correct positioning are among the most consequential things done for a long-stay patient.
A sedated patient may not close their eyes fully or produce tears, and the cornea dries, ulcerates and can scar permanently. Eye care prevents an avoidable loss of sight and is one of the most frequently omitted tasks.
The mouth of a ventilated patient becomes colonised with organisms that are then aspirated into the lungs. Regular mouth care is infection prevention with direct evidence behind it, not hygiene.
Survivors consistently rank thirst among the worst things they experienced, and it is rarely documented or treated. Mouth moisture, lip care and simply acknowledging it matters more than its simplicity suggests.
Conversations over an unresponsive patient, an uncovered body, lights on all night. Patients remember being talked about and being exposed, and neither costs anything to prevent.
Glasses, hearing aids, dentures, a photograph, familiar music. These restore some of the person and they materially reduce delirium, which makes them clinical rather than sentimental.
Unresponsive, not breathing normally, no signs of life. Agonal gasping is frequently mistaken for breathing and delays resuscitation, and that mistake is one of the commonest in an arrest.
Early, hard, fast, uninterrupted compressions with minimal pauses are what produce survival, and every pause reduces the chance. Almost everything else is secondary to good compressions.
Some rhythms respond to a shock and some do not, and early defibrillation in the shockable ones is the single most effective intervention. Knowing where the defibrillator is and how to use it is a general nursing skill.
Low oxygen, low volume, high potassium, low temperature, a collapsed lung under pressure, fluid around the heart, poisoning, a clot. Resuscitation without seeking the cause rarely succeeds.
Most in-hospital arrests are preceded by hours of abnormal observations. The most effective resuscitation work happens in the hours before, and that is a nursing argument.
Families hold the history, the person's wishes, the knowledge of what normal looks like, and the capacity to comfort. Treating them as an interruption loses clinical information and adds avoidable suffering.
Frightened people retain little and different staff saying slightly different things destroys trust. Repeating the same message plainly, and writing down the key points, is what actually informs somebody.
Holding a hand, washing a face, bringing music, being present at a turn. Participation reduces helplessness for them and is frequently good for the patient, and it costs nothing.
Relatives of critically ill patients develop anxiety, depression and traumatic stress at high rates, made worse by exclusion and poor communication. Attending to them is legitimate clinical work.
Children who are prepared honestly and supported generally cope better with seeing a relative in intensive care than with being excluded and imagining it. Exclusion is frequently for the adults' comfort.
Sedated and ventilated patients hear conversations, alarms and what is said about them, and survivors report remembering it. Speaking to the patient rather than only about them is the baseline.
Suction, turning, washing and procedures done to a person who cannot see them coming are frightening. A sentence of explanation before each one is the difference between care and assault as it is experienced.
Writing, pointing, boards, blinking, mouthing, a speaking valve. The inability to communicate is described by survivors as among the most distressing parts of the whole experience, and it is solvable with effort.
A delirious patient may be frightened, convinced of things that are not happening, or believing they are being harmed. Calm repeated orientation, and not arguing, is more effective than correction.
A record kept of what happened, in plain language, helps survivors reconstruct a period they remember as fragments or nightmares. It reduces later psychological harm and it is written by nurses and families.
Continuing organ support that cannot lead to a recovery the patient would accept prolongs dying rather than life. Recognising that point, and saying it, is a clinical judgement rather than an abandonment.
Stopping ventilation or circulatory support is accompanied by intensive attention to comfort, breathlessness, secretions, agitation and the family's presence. The intensity of care does not fall; its aim changes.
Previously expressed wishes, advance decisions, and what the family knows of their values carry weight, and finding out what they said when well is real clinical work. Nurses are frequently the ones who know.
Breathlessness, secretions, agitation, pain and fear are anticipated and treated. Planning for them in advance, rather than responding as they arise, is what produces a peaceful death.
A withdrawal proceeding while some staff disagree causes lasting distress and inconsistent care. Space to discuss it, including for nurses who have cared for the person for weeks, is part of doing it properly.
Discussion of donation follows, rather than accompanies, the recognition that death is inevitable or has occurred, and it is conducted by people trained for it. Conflating the two conversations damages trust irreparably.
Where donation follows death confirmed by neurological criteria, that determination is made rigorously and independently of any donation question. Understanding this is what allows a nurse to answer a family's doubts honestly.
Relatives frequently ask the bedside nurse what they should do, whether it will disfigure the person, whether the death is certain, and what their faith permits. Being able to answer plainly and without pressure matters.
A potential donor receives active physiological care to preserve organ function, and continues to be treated as a person — washed, spoken to, and their dignity maintained. Both things are true at once.
A family declining donation must experience no change in how they or the patient are treated. Any hint otherwise is a betrayal of the trust that makes donation possible at all.
Physical weakness, breathlessness, nerve damage, hair loss, weight loss, poor concentration, memory gaps, nightmares and anxiety persist for months to years. Discharge from the unit is an early point in recovery, not its end.
Muscle lost in intensive care takes months to rebuild and some people never fully recover strength, which affects work, independence and identity. Warning people of the timescale prevents them concluding they have failed.
Traumatic stress, depression and anxiety are frequent after critical illness, driven partly by delirium, frightening memories and the inability to communicate. It is not weakness and it responds to being treated.
Survivors frequently have no memory of weeks, or vivid false memories of harm. A diary, and a chance to talk through what actually happened, addresses this directly.
Most survivors are discharged without any structured follow-up for these problems, and present to primary care with symptoms nobody connects to their admission. Saying what to expect is the minimum.
Moral distress, traumatic stress, exhaustion and burnout are common among critical care staff, driven by repeated death, futile treatment, and being unable to provide the care one believes is right. Naming it is not weakness.
It arises from knowing what is right and being unable to do it — continuing treatment that harms, or having too few staff to care properly. It is a systems problem expressed as personal suffering.
Outcomes in critical care are associated with nurse staffing levels. Raising a concern about staffing is therefore a patient safety act, and it is legitimate professional conduct.
Structured opportunities to discuss deaths and difficult cases reduce lasting harm to staff, and informal support between colleagues does a great deal of the work. Both need protecting rather than fitting in.
People leave critical care because of what it costs them, and that is a reasonable response to a hard job rather than a personal inadequacy. A profession that says so retains more people than one that does not.
Recognising deterioration, particularly respiratory rate; sepsis and the first hour; airway assessment first; the meaning of a normal blood pressure in a shocked patient; and delirium prevention.
Waiting for blood pressure to fall before escalating; estimating rather than counting respiratory rate; giving fluid without identifying the mechanism of shock; treating a reassuring gas in a tiring patient as reassurance; sedating a distressed patient without looking for pain or a cause; mistaking agonal gasping for breathing.
Airway, breathing, circulation, disability, exposure. Escalate early and loudly. Sepsis is time-critical. Assess the patient before the monitor. Treat pain before deepening sedation. Look for the cause of every alarm.
Count the respiratory rate for a full period. Total the fluid balance. Touch the patient's feet. Record the tube depth. Say what you are about to do before you do it. Ask the family what normal looks like.
Critical care rewards noticing small changes early and saying so loudly. Every large catastrophe in this manual was preceded by a small finding that somebody wrote down and nobody acted on.
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.
