CCRN practice question: Musculoskeletal, Neurological, Behavioral/Psychosocial

Musculoskeletal, Neurological, Behavioral/PsychosocialDifficulty 2/5

A previously calm ventilated patient becomes acutely agitated overnight. What should be assessed first?

  1. AApply physical restraints and reassess in the morning with the day team
  2. BRequest an urgent psychiatric consultation for the behavioural change
  3. CIncrease sedation to protect the airway and prevent self-extubation
  4. DScreen for hypoxaemia, pain, bladder distension and withdrawal first
Show answer and rationale

Correct: D. Acute agitation is a symptom. Hypoxaemia, pain, urinary retention, withdrawal and metabolic causes must be screened before sedation, which would otherwise mask a treatable deterioration.

  • C — Sedating first can conceal hypoxaemia or another emergency.
  • A — Restraints do not diagnose the cause and carry their own harms.
  • B — A psychiatric cause is a diagnosis of exclusion in a ventilated ICU patient.
