Clinical Assessments & Deterioration

Head-to-Toe Systems Assessment

Not a checklist — a conversation. What to look for, what actually matters, and how to do it without feeling awkward.

You’ve probably been shown the head-to-toe checklist in university — tick boxes, perfect order, zero mess. Real ward life? It never goes like that. Patients get tired, machines beep, phones ring, and halfway through you realise you’ve skipped half a system. That’s okay — this guide is for the ward, not the exam hall.

This is a practical, systems-focused framework that works alongside your observations, your GCS, and your ABCDE checks. It’s about noticing things before they become emergencies. Every section tells you what to look, listen, feel, and ask — and exactly what counts as normal, what needs watching, and what to report straight away.

Why This Matters — The Evidence Base

NICE clinical guidelines repeatedly emphasise that regular systematic assessment — not just vital signs — is the most reliable way to detect deterioration early. The Royal College of Nursing (RCN) confirms that a structured approach reduces missed signs, improves consistency between staff, and gives you a clear baseline to spot change against.

The honest truth? Many students feel they’re just going through the motions. But when you know what each finding actually means — not just what to write down — you start noticing patterns. That’s when you become a safe nurse. That’s what this guide is building.

Before You Start — Set It Up Right

• Explain clearly: “I’m going to have a quick look from head to toe to make sure everything’s okay — I’ll tell you what I’m doing as I go.” Anxiety changes vital signs and behaviour — clarity calms both of you.
• Privacy and dignity: Only expose what you need to. Keep doors closed, curtains drawn. This isn’t just politeness — it’s professional duty (NMC Code: Respect, Protect, Promote).
• Start with what they tell you: “How have you been feeling today? Any soreness, tightness, or things you’ve noticed?” Patient report is often your earliest warning sign — listen first.
• Work flexibly: If they’re short of breath sitting up, do upper body first then lower when they’re rested. Order matters less than thoroughness.

Head, Face & Neck — Neurological & Sensory Window

• General appearance & behaviour: Posture, alertness, eye contact. Are they unusually quiet, restless, drowsy, or agitated? Fluctuating confusion = delirium until proven otherwise — see Neurological Observations.
• Skin & lips: Pale, flushed, clammy, dry, blue-tinged (central/peripheral cyanosis), yellowing (jaundice), rash, or breaks? Dry cracked lips can signal dehydration; blistering/crusting may indicate infection or mucous membrane issue.
• Eyes & vision: Pupils as per neuro obs — size, equality, reaction. Redness, discharge, drooping lids, swelling? Blurred or sudden loss of vision needs referral.
• Mouth & throat: Tongue dry/furred = dehydration. White patches = thrush. Bleeding gums, ulcers, difficulty swallowing? Swollen neck glands, thyroid enlargement, stiffness or pain turning head?

Respiratory — Breathing & Oxygenation

• Rate, depth & effort: Normal 12–20 breaths/min. Shallow, deep, fast (>25), slow, irregular? Using neck muscles, shoulders, or pursed lips to breathe? Tracheal tug, chest indrawing = serious sign.
• Symmetry & shape: Does chest move equally both sides? Barrel shape, sunken base, curvature? Asymmetry = collapse, effusion, or injury until ruled out.
• Listen — front & back: Clear = good. Crackles = fluid/oedema; Wheeze = narrowed airways; Coarse sounds = secretions; Absent/reduced = air not reaching space. Document exactly where heard — not just “chest sounds abnormal”.
• Cough & sputum: Dry, productive, persistent? Clear/white = normal; Yellow/green = infection; Red/blood = urgent review; Frothy pink = pulmonary oedema — escalate immediately.
• Oxygen & tolerance: On air or device? Saturations target documented? Can they speak full sentences or need to pause? How far can they walk before stopping — change from normal = deterioration.

Cardiovascular — Heart, Pulse & Circulation

• Pulse: Rate, rhythm, strength — radial first, then check pedal/foot if circulation concern. Regular, irregular, bounding, thready? New irregularity = seek medical review.
• Blood pressure & perfusion: Compare to their normal — not just textbook numbers. Drop >20mmHg systolic when sitting to standing = postural hypotension. Capillary refill <2 secs = good; >3 = poor circulation/shock risk.
• Heart sounds & rhythm: Regular or extra sounds? Murmurs may be known — new or changing murmur = concern. Chest pain, pressure, radiating to jaw/arm/back = follow protocol immediately — don’t delay.
• Oedema & skin: Puffy ankles, shins, sacrum — press firmly 5 secs: indentation = pitting. Both sides = fluid overload; one side only = DVT risk — measure and escalate. Skin warm/dry vs cool/mottled — mottling = late sign, urgent.

Gastrointestinal & Nutrition — Belly, Bowels & Intake

• Abdomen: Soft or hard/distended? Tender anywhere — light pressure first, watch their face not just their words. Rebound tenderness = surgical concern. Bowel sounds active in all 4 quadrants — absent or quiet = ileus, obstruction.
• Appetite & intake: Eating/drinking normally? Recent weight loss/gain? Nausea, vomiting — what colour, how much, how often? Coffee-ground or fresh blood = urgent review.
• Bowels: Last opened — colour, consistency, blood, mucus? Constipation is common and often overlooked — can cause confusion, nausea, retention, delirium. Check regularly.
• Fluid balance: See full guide — Fluid Balance & Status Assessment. Dehydration = dry mouth, concentrated urine, headaches, drowsiness. Overload = raised JVP, crackles, oedema, weight gain.

Genitourinary & Skin Integrity — Output & Protection

• Urine: Passing? Amount, colour, clarity, odour? Burning, frequency, urgency, incontinence, retention? Dark/decreased = dehydration; Cloudy/smelly = UTI; Visible blood = investigate. Catheter — site clean, no leak, tubing free of kinks.
• Skin & pressure areas: Check sacrum, heels, elbows, back of head — any redness that doesn’t fade within 10 mins = pressure damage. Blanching? Warmth? Broken skin? Document exact size, colour, site, and reposition. Every shift.
• Devices & wounds: Drips, drains, tubes — site clean, secure, no redness/swelling/leakage? Dressings dry and intact? Wounds — pink healthy tissue = healing; Black/necrotic = needs debridement; Yellow slough = moisture/cleansing focus.

Musculoskeletal & Mobility — Movement, Strength & Safety

• Strength & symmetry: Hands squeeze equally? Push/pull feet against resistance? Weakness on one side = stroke until ruled out. Generalised weakness = infection, fatigue, medication, or systemic cause.
• Mobility & balance: How do they stand? Walk? Steady, shuffling, leaning, holding furniture? Risk of falls = document and implement plan. Pain with movement — where, type, scale 0–10, what eases it.
• Joints & limbs: Swollen, red, hot, painful? Deformity? Previous surgery hardware? Casts/splints fitting well? Circulation beyond device checked and documented.

Pain — The 5th Vital Sign

Never assume “they’d tell me”. Some patients won’t — especially long-term or stoic. Ask clearly and document fully:

• Where exactly? One spot or spread?
• What does it feel like? Sharp, dull, burning, throbbing?
• Scale 0–10 now — and at best/worst today
• Started when? Triggered by what?
• What helps — and what doesn’t?
• Effect on sleep, appetite, mood, movement?

Pain changes breathing, heart rate, blood pressure, and mood — and unrelieved pain delays recovery. It is not “just something to put up with”. Report it, escalate it, document it.

Documenting Properly — Protection & Continuity

Write what you saw, heard, felt, and were told — not what you think it means. Be specific, objective, and honest:

• ✅ “Right ankle swollen, warm to touch, calf tender — patient reports pain 6/10” — good
• ❌ “Ankle looks a bit swollen — maybe DVT?” — don’t guess, just describe
• ✅ “Lungs clear upper/mid, crackles heard at both bases” — specific
• ✅ “Patient states: ‘I feel so tired I can hardly keep my eyes open'” — quote directly

If you’ve checked and everything is normal — write that too. “Systematic assessment performed: respiratory, cardiovascular, GI, GU, neuro, musculoskeletal systems within expected parameters. No new concerns identified.” Blank entries don’t mean “fine” — they mean “not done”.

Red Flags — Escalate Immediately

• Sudden confusion, drowsiness, weakness, slurred speech, facial droop
• Chest pain, breathlessness at rest, frothy pink sputum
• Cold, clammy, mottled skin; rapid thready pulse; dropping BP
• Uncontrolled pain, new bleeding, coffee-ground vomit/blood in stool
• One swollen, hot, painful leg — measure calf and escalate
• Not passed urine 6+ hours — or painful distended bladder
• Any change from their normal that doesn’t settle

The Honest Reality — It Gets Easier

Your first few assessments will feel clunky. You’ll forget a system. You’ll feel like you’re taking too long. That’s not failing — that’s learning. Every nurse you admire went through exactly the same stage.

Over time you’ll develop that “nurse’s instinct” — the quiet sense that something’s off even if numbers look fine. That comes from doing this systematically, every time, and noticing what normal actually looks like. Trust that gut feeling — and always back it up with what you’ve seen and measured.

And remember: asking a mentor to double-check something isn’t weakness. It’s safe practice. It’s exactly what you should do.
