Skin Assessment: the method, the errors, and the exam
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
A skin assessment is a systematic head-to-toe inspection and palpation of skin integrity, colour, temperature, moisture, and turgor, paired with a Braden score on admission to quantify pressure injury risk. The heels and the sacrum are checked first because they break down fastest. It is repeated at least daily and whenever risk factors change.
Why this skill decides answers
Skin assessment sits at the intersection of two things exams reward: a measurable score and a physical finding. The Braden scale gives you a number on admission, from sensory perception through friction and shear, and that number determines the whole plan, from turning frequency to whether a pressure-redistribution mattress is ordered. A stem that mentions a Braden score of 12 is telling you the patient is high risk before it tells you anything else.
The physical exam half is just as heavily tested because it is where errors are visible. A stage 1 pressure injury is non-blanchable redness, still intact skin, and it is reversible if caught. Miss it at the sacrum or heel and it can progress to a full-thickness wound within days. Exam writers use this skill to test whether you know where to look first, not just what a wound looks like once it has already formed.
How to do it reliably
Complete a Braden score on admission and repeat it on a schedule set by facility protocol or whenever the patient's condition changes significantly, such as after surgery or a drop in mobility. Follow it with a full head-to-toe skin inspection: scalp, ears, and behind the ears; under skin folds and breast tissue; between fingers and toes; and every pressure point the patient's position exposes.
The heels and the sacrum go first and get the closest look, because they carry the highest pressure in a supine patient and break down fastest. Inspect, then palpate for temperature and induration, and always check for blanching by pressing gently and releasing. Assess turgor at the sternum or forehead rather than the back of the hand in an older adult, since hand skin loses elasticity with age independent of hydration status. Document findings in specific, measurable terms: location, size in centimetres, colour, drainage, and whether redness blanches, rather than a general note that skin is "intact" or "a little red."
The common errors
The most frequent error is skipping the heels and sacrum in a patient who is sitting up or ambulatory that shift, on the assumption that mobility rules out risk; a patient can be up in a chair for meals and still spend eighteen hours a day supine. Another is documenting "skin intact" without checking under a brace, cast, or compression stocking, where pressure and moisture build unseen.
Confusing a stage 1 pressure injury with simple erythema from friction is a common misread; the blanch test is what separates them, and skipping that test turns a documented finding into a guess. Relying on the Braden score alone without a visual check is another gap, since the score predicts risk but does not replace looking at the skin. Charting turgor from the hand in an elderly patient, then concluding dehydration on a finding that is really just age-related skin change, is a related error worth watching for.
Drills that build it
Practise scoring the Braden scale from a written vignette until you can place a patient's sensory perception, activity, mobility, nutrition, and friction/shear without hesitating on any subscale, then total the score and state the risk category from memory.
Run mock head-to-toe exams in a fixed order every time, sacrum and heels first, so the sequence becomes automatic under time pressure. Pair each finding with the documentation language you would actually chart: stage, size, colour, drainage, blanching. Practise distinguishing a stage 1 pressure injury from a moisture-associated skin lesion in photos, since the two are commonly confused and tested against each other.
Exam application
Expect a question that gives a Braden total and asks what intervention follows: a low score points to a pressure-redistribution surface, a turning schedule of at least every two hours, and heel offloading, not just "monitor skin." Another common format describes non-blanchable redness over the sacrum and asks you to stage it or to select the correct intervention, where the correct answer protects the area from further pressure and shear rather than applying a dressing meant for a deeper wound.
Watch for stems that test prioritisation: given several patients, the one with the lowest Braden score or an existing stage 2 injury is assessed first. Distractors often offer a plausible-sounding but generic answer, like applying lotion to broken skin, when the correct action is to protect and offload the area and notify the provider or wound care team.
Quick reference
Score the Braden scale on admission and reassess per protocol or with any condition change. Inspect head-to-toe daily, checking heels and sacrum first regardless of the patient's activity level that shift. Use the blanch test to separate stage 1 pressure injury from ordinary erythema, and check turgor at the sternum or forehead in older adults rather than the hand.
Document location, size, colour, drainage, and blanch status in specific terms every time. Low Braden score or any existing pressure injury changes the plan: turning schedule, offloading, and surface selection, not just closer observation.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our basic care and comfort practice questions are the closest set to what this page covers.
One question from the basic care and comfort set
A nurse is preparing to feed a client who had a stroke and has mild dysphagia. Which action best reduces the risk of aspiration?
Rationale
Upright at 90 degrees with a chin tuck narrows the airway entrance and directs the bolus toward the esophagus — it is the single highest-yield positioning intervention for dysphagia. Thin liquids and straws move fastest and aspirate most easily, side-lying removes the gravity you want, and large bites overwhelm a swallow that is already impaired.
Answer: B
Common questions
How often should a Braden score be reassessed after admission?
Facility protocols vary, but a common approach is reassessment every shift or every 24 hours for at-risk patients, and immediately after any significant change in condition such as surgery, sedation, or a new mobility limitation. The admission score sets the baseline; it should never be treated as fixed for the length of stay.
What is the difference between a stage 1 pressure injury and simple redness from friction?
A stage 1 pressure injury is non-blanchable, meaning the redness does not fade under gentle pressure, and the skin remains otherwise intact. Friction-related redness typically blanches and resolves once pressure is relieved. The blanch test is the deciding step, so it should not be skipped when documenting either finding.
Why check turgor at the sternum instead of the hand?
Skin on the back of the hand loses elasticity with normal ageing independent of hydration, which can produce a false impression of dehydration in an older adult. The sternum or forehead reflects hydration status more reliably across age groups and is the preferred site for this check.
Do I still need to check the heels if the patient has been up in a chair?
Yes. Sitting up for part of a shift does not eliminate the hours a patient likely spends supine, and the heels remain a high-pressure point regardless of daytime activity. Skipping them on the assumption of adequate mobility is one of the most common assessment errors.
What should be documented for a new skin finding?
Record exact location, size in centimetres, colour, presence and type of drainage, and whether the area blanches under gentle pressure. Vague terms like "a little red" or "skin intact" without detail make it impossible for the next clinician to judge whether the finding is new, static, or worsening.
