Pressure Injury Risk Assessment: the method, the errors, and the exam

Why this skill decides answers

Pressure injury questions test judgement, not recall of a tool. Most candidates can recite that the Braden Scale scores sensory perception, moisture, activity, mobility, nutrition, and friction/shear, and that a lower total score means higher risk. That knowledge alone answers almost none of the questions written around it, because the exam is testing whether you know when to act on a score, not whether you know the categories exist.

The skill decides answers because risk is not fixed. A patient admitted mobile and continent can become bed-bound and incontinent within days of a stroke, sedation, or post-operative recovery, and the Braden score taken at admission stops describing that patient almost immediately. Questions are built around this gap: a scenario gives you an admission score, then changes the patient's condition, and asks what you do next. If you answer from the original score, you get it wrong. If you recognise that the score needs repeating, you get it right.

How to do it reliably

Score on admission, using the full tool rather than a mental estimate. Each subscale carries its own criteria; guessing a total from a general impression of the patient produces a number that looks precise and is not. Document the score and the date, because the next assessment is measured against this baseline.

Reassess on a fixed schedule appropriate to setting, commonly every shift in acute care and less frequently in stable long-term settings, and immediately with any change in condition: a new sedative, a fall, a change in continence, a drop in mobility, or a surgical procedure. The score is not the endpoint. It sets the interventions, repositioning frequency, support surface selection, moisture management, nutrition referral, and those interventions must scale as the score worsens. A Braden score of 12 that gets the same two-hourly turning schedule as a score of 18 is a system that has stopped listening to its own data.

The common errors

The single most consistent error is treating the admission score as permanent. It gets charted once, filed, and never revisited even as the patient deteriorates, so the paperwork says low risk while the sacrum says otherwise. This is the specific failure the exam is built to catch.

The second error is scoring from impression instead of the criteria. A nurse who feels a patient is doing fine may round activity or mobility upward without checking the actual descriptor, which quietly inflates the score and removes the patient from a prevention pathway they need. The third is separating the score from the intervention: assessing correctly, then not adjusting turning schedules, surfaces, or skin checks to match the new risk level. A score with no consequence is not risk assessment, it is documentation.

Drills that build it

Run a single patient through a deteriorating trajectory on paper: mobile and continent on day one, then sedated and incontinent by day three after a procedure. Score the Braden Scale at each point and write out exactly what changes in the care plan between the two scores. If the interventions look identical, the drill has found the gap.

Practise identifying reassessment triggers without being told to. Take a set of short scenarios, some containing a change in condition and some not, and sort them into reassess now versus continue current schedule. Then pair each score band with its matching intervention set from memory: what changes between a 15 and a 11, and what changes again at 9. Repeat with different starting conditions until the reassessment trigger is the first thing you notice, not the last.

Exam application

NCLEX questions on this topic tend to embed the risk-changing event inside a longer scenario rather than naming it directly, so you are watching for a new diagnosis, a new medication, a drop in oral intake, or a period of immobility, and asking whether a reassessment is now due. The correct answer is usually the option that reassesses and adjusts care, not the one that continues the existing plan because the last score was reassuring.

Distractors typically include an option that repeats the current interventions unchanged, an option that treats the Braden score as diagnostic of an existing injury rather than predictive of future risk, and an option that delays reassessment until a scheduled time even though the scenario describes an acute change. Read for the change in condition first; it usually tells you which answer the question wants.

Quick reference

Score on admission with the full Braden Scale, six subscales, lower total means higher risk. Reassess on your unit's schedule and immediately after any change in condition, a new sedative, reduced mobility, incontinence, surgery, or a fall. Match interventions to the current score, not the admission score, turning frequency, support surface, moisture care, and nutrition all scale with risk. A static score on a deteriorating patient is a paperwork exercise, not an assessment.
