A rigid box, and the observation that finds trouble before any machine does
Neurology is the subject where a nurse's repeated observation is the monitor. The skull cannot expand, so pressure rises when anything inside it does, and the level of consciousness falls before the pulse, the blood pressure or the breathing change. That ordering is why deterioration inside the head is found by somebody assessing a patient every half hour rather than by equipment, and why the single most dangerous habit in this subject is letting a drowsy patient sleep because they look peaceful. It is also the subject where time is measured in minutes: brain tissue dies on a schedule, treatment works only inside a window, and the most valuable sentence in the whole encounter is when the person was last seen well.
The skull is a rigid box holding brain, blood and fluid. If any one of those increases, another must give way or the pressure rises. That single fact governs head injury, bleeding, swelling, tumour and infection inside the head, and it explains why a small extra volume can be catastrophic once the capacity to compensate has been used up.
When pressure rises, the level of consciousness drops before the pulse, blood pressure or breathing change. That ordering is the reason repeated neurological observation detects deterioration earlier than anything else available, and the reason it is usually a nurse who detects it rather than a machine.
A patient who was answering questions and is now only obeying commands has deteriorated, even though both look acceptable on a chart. The value of the observation is entirely in the comparison with the last one, which is why it is recorded as a series and never as a single impression.
Changes in pupil size and reaction indicate pressure that has already become severe. By the time a pupil is enlarged and sluggish, a great deal has already happened, which is why pupils are checked but never relied on as an early sign.
Consistency between observers is what makes a series meaningful. Two nurses assessing the same patient differently produce a chart that looks like deterioration or improvement when nothing has changed, so the wording, the stimulus and the scoring are kept identical between people and between shifts.
Standard assessment records whether the eyes open, what the person says, and how they move, each scored consistently. The three together describe the level of consciousness better than any single one, and the best response on each is what is recorded rather than an average impression.
Speak first, then a firm touch, then a painful stimulus applied in an agreed way. Escalating in a fixed order means that two nurses on different shifts have measured the same thing, and skipping straight to pain in a drowsy patient both hurts them and loses the finding.
Weakness on one side is a finding about where the problem is, not just how bad it is. Comparing the two sides at every assessment, and recording them separately, is what turns an observation into localisation, and it is what people leave out when they are hurried.
Asking somebody to push and pull against your hand, on both sides, takes seconds and detects weakness before it is obvious in how they move. In an unconscious patient, whether a limb withdraws, localises or does nothing to a stimulus carries the same information.
Recording that a patient was drowsy means little. Recording that they opened their eyes to voice, said their own name but not the year, and moved the left arm less than the right means something to whoever reads it next, and it is the difference between a record and a note.
Most strokes are a blocked artery, some are a bleed, and in both the tissue supplied dies within hours. Treatment that restores flow works only inside a limited window from the moment symptoms began, which makes the timing question the most valuable thing said in the encounter.
The clock runs from when the person was last seen well, not from when the problem was noticed. Somebody who woke with weakness may have had it for eight hours, and asking when they went to bed and when they were last seen normal is what determines what can be offered.
Sudden facial droop on one side, weakness of one arm, and speech that is slurred or makes no sense are the signs campaigns teach because they catch most strokes. Sudden loss of vision, sudden severe imbalance or a sudden very severe headache unlike any before also matter and are missed more often.
The main motor pathway crosses low in the brainstem, so a lesion on one side of the brain weakens the other side of the body. Language usually sits on the left, which is why right-sided weakness and speech difficulty so often appear together, and why left-sided weakness more often affects awareness of that side.
Stroke frequently impairs swallowing, and material entering the lungs causes a pneumonia that is among the commonest causes of death afterwards. Nothing is given by mouth — not water, not a tablet — until swallowing has been assessed by somebody trained to do it.
Most strokes are caused by a blocked artery and a minority by a vessel bleeding, and the two look identical at the bedside. That is the entire reason a scan happens before any treatment is given, because the drug that dissolves a clot is catastrophic in somebody who is already bleeding. A nurse who understands this understands why nothing can be given until the scan is done, why the transfer is urgent, and why the answer to an anxious family asking why nothing is happening yet is that the wrong treatment here would kill.
Positioning, swallowing safety, pressure area care, early mobilising, bladder management and preventing clots all happen in the first days and all shape the eventual outcome. Very little of it is technical and almost all of it is nursing, which is why stroke units save lives largely through organised nursing care.
A person may not recognise that one side of their body or their surroundings exists, eating only half a plate and shaving only half a face. It is not stubbornness or poor vision, and approaching from the affected side, and prompting them to attend to it, is part of the treatment.
Somebody may understand everything and be unable to produce words, or produce fluent speech that makes no sense. Assuming that difficulty speaking means difficulty understanding is a common and humiliating error, and it is why speaking normally, allowing far more time, and using writing or pictures matters.
Depression after stroke is common, worsens recovery, and is routinely dismissed as an understandable reaction requiring no attention. Understandable and treatable are not opposites, and treating it improves the physical recovery as well as the mood.
Relatives are frequently expected to take over care with almost no preparation, and their confidence in the first weeks determines whether somebody stays at home. Teaching them properly, watching them do it, and telling them what would be a reason to call is part of the discharge rather than an addition to it.
Bleeding inside the skull can develop over hours after an apparently minor blow, which is why somebody who was talking and is now drowsy is an emergency. The phrase used for that pattern — talk and deteriorate — describes exactly the patient who dies because observations were not repeated.
Conscious level, pupils, limb movement and observations, repeated at intervals set by local policy and more often if anything changes. The frequency matters more than the detail, because a single assessment cannot show a trend and it is the trend that reveals the bleed.
Worsening headache, repeated vomiting, increasing drowsiness, confusion, weakness on one side, a fit, or clear fluid from the nose or ear. Families taking somebody home after a head injury are given these in writing, because at three in the morning nobody remembers a verbal list.
A head injury in somebody who has been drinking is assumed to be alcohol until it is proved to be a bleed, and that assumption kills people. Reduced consciousness in a person who has had a head injury is a head injury problem until somebody has excluded it.
Small children can lose a significant proportion of their blood volume into a head injury, and older people bleed inside the skull after falls that seem trivial, particularly if they take blood-thinning medicines. Both groups need a lower threshold rather than a higher one.
Abnormal synchronised electrical activity in the brain, producing anything from a brief absence to a generalised convulsion. It is a symptom rather than a diagnosis, which is why a first seizure prompts a search for a cause rather than a label.
Protect the head, remove danger from around them, do not restrain, do not put anything in the mouth, note the time, and observe exactly what happens. Nothing goes in the mouth — that instruction exists because people have had teeth and jaws broken by well-meaning attempts.
What the person was doing beforehand, how it began, which part moved first, whether they were responsive, how long it lasted, whether they were incontinent, and how long recovery took. Nobody else will see it, and the diagnosis frequently rests entirely on what a nurse wrote down.
A seizure that continues beyond a few minutes, or repeated seizures without recovery in between, is a medical emergency with a real mortality that rises with every minute. Recognising that it has crossed from a seizure into that state is what triggers the response.
Low glucose, low sodium, infection, head injury, drugs, alcohol withdrawal, pregnancy-related illness and raised pressure in the skull. Several of these are rapidly correctable, which is why checking a glucose in anybody who has fitted is standard rather than optional.
Most of the burden of epilepsy is not the seizures themselves but everything arranged around them — whether somebody can drive, swim, bathe alone, cook, work at height, or be left with a small child. Advice on these is specific, differs by country and by how well controlled somebody is, and is frequently never given at all. A patient who has been told nothing makes their own rules, and those are usually either far more restrictive than necessary or dangerously less so.
Infection of the membranes around the brain can kill a previously well person within hours. Fever, severe headache, neck stiffness, dislike of light, vomiting, confusion and drowsiness together are the classic picture, and the speed of treatment matters more than the completeness of the assessment.
An infant may have none of the classic signs — instead poor feeding, irritability, a high-pitched cry, floppiness, a bulging soft spot on the head, or simply being unlike themselves. A parent saying the baby is not right is clinical information in this situation.
A rash that does not blanch when pressed indicates bleeding into the skin and, with fever, suggests a severe bloodstream infection. It is a late sign rather than an early one, so waiting for it before acting is waiting too long, and its absence excludes nothing.
Some causes spread from person to person through droplets, so precautions are applied until the organism is known and close contacts may need preventive treatment. Establishing who has shared the person's air is part of managing the case.
Infection can also form a collection inside the brain or inflame the brain tissue itself, producing headache, fever, seizures, confusion and changing conscious level over days. Personality change or confusion with fever is the presentation that gets attributed to something else for too long.
Several neurological diseases worsen over years, affecting movement, speech, swallowing, breathing, continence and thinking in different combinations. What matters to the person is rarely the diagnosis and almost always what they can still do, which is why asking about function rather than symptoms produces a more useful assessment.
Slowness, stiffness, tremor and difficulty starting movement change every practical task, including getting out of a chair, turning over in bed and getting to a toilet in time. Timing of medicines matters enormously here, and a dose given late on a ward can leave somebody unable to move for hours.
Some diseases relapse and remit, so a person may be entirely well between episodes and severely disabled during them. Fatigue is frequently the most disabling symptom and the least visible, and it is the one most often dismissed by people who saw them walking last month.
Progressive neurological disease eventually affects the muscles of swallowing and breathing, and decisions about feeding tubes and breathing support are best discussed long before the crisis. Those conversations are easier on a calm day and are routinely left until there is no time.
Bladder and bowel problems are common, deeply distressing, and rarely raised by patients. Asking directly, without embarrassment, and offering practical management is one of the highest-value conversations in this subject and one of the least often held.
Anybody with a significant injury and neck pain, weakness, numbness or reduced consciousness is treated as having a spinal injury until it is excluded. Moving somebody badly can convert a partial injury into a complete one, and there is no way to undo it.
The higher the injury, the more is affected, and injuries high in the neck affect the muscles of breathing. That is why a person with a high injury is watched for respiratory failure rather than only for weakness, and why breathing is assessed repeatedly in the first days.
A cord being compressed — by a tumour, an abscess or a disc — produces progressive weakness, changed sensation, and disturbance of bladder or bowel. New difficulty passing urine, or numbness around the perineum, with back pain, is a surgical emergency, and hours determine whether function returns.
Pressure damage, clots, chest infections, contractures, constipation and bladder infection all follow immobility, and all are prevented by nursing rather than treated by medicine. This is the clearest example in the subject of outcome being determined by routine care.
In injuries above a certain level, a stimulus below the injury — a full bladder, constipation, a pressure sore — can trigger a dangerous surge in blood pressure with a pounding headache and sweating. The treatment is to sit them up and find the cause, most often a blocked catheter.
Headache worse in the morning or on coughing, vomiting, progressive drowsiness, and changes in pupils. The sequence matters: conscious level falls before pupils change and long before pulse and blood pressure move, which is why the neurological chart is the monitor.
Keeping the head in a neutral position with the bed raised aids venous drainage from the head, and a twisted neck or a tight collar obstructs it. This is one of the few situations where how somebody is lying is genuinely part of the treatment rather than comfort.
Pain, fear, coughing, straining, fever, seizures and a full bladder all raise pressure inside the head. Treating each of those is therefore part of managing the pressure, which is why analgesia, calm, temperature control and a working catheter matter in this patient.
A rising blood pressure with a slowing pulse and irregular breathing is a very late sign of severe pressure and indicates the brainstem is being compromised. By then a great deal has been lost, and its presence means an emergency rather than a finding to record.
Deterioration commonly happens at night when staffing is thinnest and a drowsy patient looks like a sleeping one. Waking somebody to assess them is not a cruelty; it is the only way to know the difference, and it is the observation people are most tempted to skip.
A sudden very severe headache reaching maximum intensity within seconds, unlike any before, suggests bleeding around the brain and needs urgent assessment. People describe it as being hit on the back of the head, and they frequently apologise for making a fuss.
New headache in somebody older, headache with fever and neck stiffness, headache worse on coughing or lying down, headache with weakness or visual change, headache after a head injury, or a headache that has changed its pattern. Each moves a common complaint into a different category.
Pain from damaged nerves is described as burning, shooting or electric, may follow a specific area of skin, and responds poorly to ordinary painkillers. Recognising the description matters because the approach is entirely different, and patients are frequently told the pain cannot be that bad.
In reduced consciousness, dementia or severe brain injury, pain is inferred from facial expression, restlessness, guarding, changes in breathing and rising observations. These patients are consistently under-treated, and the reason is that the measurement is harder rather than absent.
Pain increases blood pressure and intracranial pressure, stops somebody breathing deeply, and prevents sleep, all of which worsen a neurological patient. Treating it is part of the neurological management rather than a separate comfort measure.
Delirium develops over hours to days with fluctuating attention and is caused by something physical. Dementia develops over months to years with attention relatively preserved early on. Confusing them means a treatable physical cause is missed in somebody labelled as confused, and that mistake is made every day on general wards.
It indicates that something physical is wrong — infection, pain, retention, constipation, dehydration, a medicine, withdrawal, low oxygen — and it carries a real mortality. The nursing response is to hunt for the cause rather than to sedate a confused patient, because sedation treats the staff's difficulty and not the patient's.
Delirium can present as withdrawal, drowsiness and doing nothing, rather than as agitation. That version is more common, carries a worse outcome, and is almost never recognised, because a quiet patient does not interrupt anybody's shift.
Orientation, familiar faces, glasses and hearing aids actually worn, daylight, sleep protected at night, adequate hydration, pain treated, constipation relieved, and avoiding repeated moves between wards. These are the interventions with evidence, and none of them are pharmaceutical.
What is recorded as challenging behaviour is usually an unmet need — pain, needing the toilet, fear, hunger, noise, boredom, or being handled without warning. Looking for the need resolves a substantial proportion of it and avoids medicines that carry real harm in this group.
With age the brain has less capacity to absorb an insult, so an infection, a new medicine or dehydration that a younger person would shrug off produces confusion. That is why an older person presenting with confusion is examined for a physical cause rather than assumed to be declining.
Sedatives, strong painkillers, some bladder medicines and several others cause confusion in older people, and the risk rises sharply when more than one is taken. Reviewing the whole list when somebody becomes confused finds the cause more often than any scan.
A fall may be the first sign of infection, a rhythm problem, low blood pressure on standing, poor vision, a new medicine or a stroke. Recording it as a fall and not asking why is how the underlying cause goes unexamined until the second fall.
An older person who falls while taking blood-thinning medicines can bleed inside the skull after a knock that looks trivial, and it can develop over days. That combination lowers the threshold for observation and imaging rather than raising it.
A clock they can see, a window, being told the day, their own glasses, and the same faces reduce confusion measurably. Wards that do this have less delirium, which makes the layout and routine of a ward a neurological intervention.
Function after brain or spinal injury improves with repeated, graded, purposeful practice, and it does not improve much with rest. That means what happens on the ward between therapy sessions — and there are many more of those hours — determines a large part of the outcome.
If a therapist teaches a transfer one way and the night staff do it another, the patient learns neither. Consistency of approach across every shift is what makes rehabilitation work, and it requires the plan to be written where everybody actually reads it.
Doing a task for somebody is faster and it removes the practice that recovery depends on. Allowing somebody to be slow, prompting rather than completing, and tolerating an imperfect attempt is genuinely difficult under time pressure and is the entire intervention.
Walking to the toilet unaided, holding a grandchild, returning to a particular job. Goals expressed in the person's own terms are pursued; goals expressed as ranges of movement are not, and the difference shows in how hard somebody works between sessions.
Profound tiredness after stroke or head injury is a genuine consequence of the injury rather than low motivation, and pushing through it worsens performance. Planning demanding activity for the person's better hours is more effective than encouragement.
Some people use a board, a device, a gesture, or a signal agreed long ago with a relative. Finding out first prevents the most common and most damaging default, which is speaking to the relative instead of the patient, in front of the patient.
Somebody searching for a word may need many seconds, and finishing their sentence removes both the practice and the dignity. The silence feels long to the person waiting and not to the person working, and tolerating it is a skill.
Asking whether somebody would like tea, coffee or water, and whether they want it now or later, is four decisions in one sentence. Offering one thing at a time gets an answer where a compound question gets confusion.
Where speech is impaired, writing a key word, drawing, or pointing at a picture frequently succeeds where repeating a spoken sentence louder fails. Volume is the instinct and it is almost never the problem.
Hearing may persist and awareness is impossible to rule out, so explaining what you are doing, using the person's name, and not discussing them in the third person at the bedside are professional obligations. Families are listening even when the patient may not be.
Pressure damage, clots, chest infections, contractures, constipation, bone loss, muscle wasting and delirium all follow immobility. In neurology, where patients may be unable to move themselves at all, preventing that list is most of the nursing workload and most of the outcome.
Every position has its own pressure points, its own effect on breathing, and its own risk to joints and shoulders. A limb left unsupported pulls at the shoulder it hangs from, and a shoulder injured that way causes pain that outlasts the admission.
A joint held in one position shortens the soft tissue around it, and the change becomes fixed. Moving each joint through its range, every day, is what prevents a hand or a foot from becoming permanently useless, and it is the task most often deferred when a ward is busy.
Hospitals break sleep with light, noise and observations, and disrupted sleep worsens confusion, pain and recovery in exactly the patients least able to absorb it. Clustering observations, dimming lights and not waking somebody for something that could wait are neurological interventions.
An unconscious patient may not blink or close their eyes fully, and the cornea dries and ulcerates within hours. Eye care and mouth care are not comfort measures in this patient; they prevent injuries that are permanent.
Where the brainstem has irreversibly ceased to function, a person is dead even though the heart may still beat with support. The tests for this are strictly defined, performed by specific clinicians, and repeated, precisely because the consequence is absolute.
A family looking at a warm person whose chest rises will not accept an explanation given once in technical language. They need it plainly, repeatedly, with time, and with the chance to see the testing explained. Rushing that conversation is what creates lasting anger.
Where donation is being considered, the conversation is separated from the conversation about death, held by people trained to do it, and framed as an offer rather than a request. Practice differs by country and by faith, and assumptions about what a family will want are frequently wrong.
Decisions to stop treatment that is no longer benefiting somebody follow a defined process involving the clinical team, the person's known wishes and the family, and they are recorded. They are not made at a bedside by whoever is present when something fails.
Attending a death in neurology — frequently sudden, frequently in a young person — affects people and is followed by an immediate return to other patients. Acknowledging it, and checking on the most junior person present, is part of running a unit rather than an optional kindness.
A seizure in pregnancy or shortly after birth is an emergency and is assumed to be pregnancy-related until proved otherwise. It is usually preceded by rising blood pressure, headache, visual disturbance, upper abdominal pain or swelling, all of which somebody recorded and nobody acted on.
A new or severe headache in the second half of pregnancy, particularly with visual changes or high blood pressure, is assessed rather than reassured. The reassurance that it is common in pregnancy is what delays the diagnosis that matters.
A short seizure during a fever in a young child is frightening for parents and usually benign. What matters clinically is finding the cause of the fever, excluding infection of the brain and its coverings, and giving parents an explanation that prevents them living in terror of the next fever.
Children can lose a significant proportion of their blood volume into a head injury, their skull is thinner, and their signs are different — irritability, vomiting, a bulging soft spot in an infant, or simply not behaving like themselves. The threshold for observation is lower, not higher.
An injury inconsistent with the explanation, or with the child's developmental stage, is a safeguarding concern handled through the defined route rather than personally. Head injury in a baby who cannot yet roll is the classic example, and acting does not wait for certainty.
Where a scan is hours or days away, conscious level, pupils, limb power compared side to side, and the trend across time are the assessment rather than a preliminary to it. In these settings a nurse's series of observations is frequently the only evidence that exists.
A patient with a possible bleed inside the skull deteriorates on a timescale shorter than most journeys. Deciding to move somebody while they are still stable enough to travel is the clinical act, and delay in deciding is what appears in every review of these deaths.
Protect the airway, position the head neutrally with the bed raised, treat fever and pain, prevent seizures from continuing, avoid fluid overload, and keep observing. None of that requires equipment and all of it changes what a neurosurgeon receives.
A very large proportion of people with epilepsy in poorer countries receive no treatment at all, despite medicines that are inexpensive and effective. That gap is about supply, cost, distance and stigma rather than about clinical difficulty, and community nursing closes more of it than hospitals do.
In many communities epilepsy is understood as possession, contagion or punishment, and people conceal it, leave school, and are excluded from marriage and work. Explaining plainly what it is, to the family as well as the patient, is one of the highest-value conversations available in this subject.
A single neurological observation proves nothing and a series proves a great deal. Where something later goes wrong, the chart of consciousness, pupils and limb movement over hours is what any review will examine, and it cannot be reconstructed afterwards.
In a subject where treatment windows are measured in hours, an entry with an approximate time is worth much less than one with a real one. The time symptoms began, the time of the first assessment, the time of escalation and the time of response all matter.
Recording that a patient was confused is an interpretation. Recording that they did not know the year, called their daughter by the wrong name, and were trying to leave the ward is an observation, and it is the one that lets somebody else judge whether things have changed.
Escalation that is not recorded did not happen as far as any later review is concerned, and it is the entry most often missing. Naming the person contacted, the time, and what was said protects the patient first and the nurse second.
Saying a patient is drowsy says less than saying they were alert at eight, drowsy but rousable at eleven, and now take repeated stimulation to open their eyes. The direction is the clinical information and it exists only if somebody states it as a change.
A nerve running close to the surface can be injured by pressure, by a long period in one position during surgery, by a tight cast or by an injection placed wrongly. The result is weakness and altered sensation in exactly the area that nerve supplies, and it is frequently permanent. Protecting those points during positioning is a nursing responsibility that has no visible reward when it works.
Diabetes is the commonest cause worldwide of nerve damage affecting both feet symmetrically, producing numbness, burning pain and loss of the protective sensation that tells somebody their shoe is rubbing. A person who cannot feel an injury will walk on it until it becomes an ulcer, which is why foot inspection is a neurological act as much as a diabetic one.
Some conditions cause weakness that begins in the feet and climbs, over hours to days, towards the trunk. The danger is that it reaches the muscles of breathing and of swallowing, so these patients are watched for how deeply they can breathe and how well they can swallow rather than only for how far they can walk.
Some diseases attack the junction between the nerve and the muscle it controls, producing weakness that worsens with use and improves with rest. Drooping eyelids and double vision late in the day, or difficulty chewing towards the end of a meal, are the pattern, and the timing is what distinguishes it from general tiredness.
Pain from damaged nerves is burning, shooting or electric, follows the territory of that nerve, and responds poorly to ordinary painkillers. Patients are frequently told the pain cannot be that bad because nothing is visible, and recognising the description is what gets them to a treatment that works.
Recognising a stroke and establishing the time of onset, neurological observation and what a falling conscious level means, seizure management, meningitis in an adult and in an infant, and spinal precautions. The scenarios reward order of actions.
Waiting for pupil changes as an early sign; assuming reduced consciousness after drinking is alcohol; giving fluids or tablets by mouth after a stroke before swallowing is assessed; putting something in the mouth during a seizure; waiting for a non-blanching rash before acting on suspected meningitis.
Assess and record conscious level, protect the airway, establish the time symptoms began, escalate early, keep them nil by mouth where indicated, and repeat the observations rather than performing them once.
Ask when they were last seen well. Compare both sides every time. Write what you actually saw rather than a single word. Wake them to assess rather than assuming sleep. Check a glucose in anybody who has fitted.
In neurology the single observation means almost nothing and the series means everything. A chart with four consistent entries by four people is worth more than one perfect assessment, and creating that consistency is a deliberate act.
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.
