A nurse is reinforcing dietary teaching with a client who has constipation about appropriate food choices. Which of the following food selections by the client demonstrates an understanding of the teaching?

Choice A reason: Releasing restraints every 4 hours lacks context; policy requires 2-hour checks with release if safe. Scientifically, this risks neglect, as frequent assessment ensures circulation and safety, making it less precise than behavior documentation.

Choice B reason: Hourly checks are good but not the action specified; 15-minute intervals are standard for restraints. Scientifically, this underestimates risk monitoring needs, as behavior justification is a legal and clinical priority over timing alone.

Choice C reason: Client consent isn’t required for restraints in emergencies; provider orders suffice. Scientifically, imminent harm overrides autonomy, and consent isn’t feasible mid-crisis, making this impractical and misaligned with restraint protocols.

Choice D reason: Documenting behavior justifies restraints, ensuring legal and ethical use for safety. Scientifically, this aligns with standards, as specific actions (e.g., aggression) validate intervention, providing a clinical basis critical for care continuity and review.

Choice A reason: Echopraxia, mimicking movements, is linked to psychiatric conditions like schizophrenia, not delirium. Delirium features disordered cognition from physiological causes (e.g., infection), not motor imitation. Scientifically, this lacks relevance to delirium’s acute, fluctuating mental state driven by underlying medical issues.

Choice B reason: Aphasia, a language deficit, stems from brain damage (e.g., stroke), not delirium’s reversible cognitive disruption. Delirium affects attention and awareness, not specific linguistic skills. Scientifically, this is distinct from delirium’s diffuse, temporary confusion tied to systemic or metabolic disturbances.

Choice C reason: Acute onset of confusion defines delirium, a sudden cognitive decline from causes like infection or drugs. It’s reversible with treatment, featuring inattention and disorientation, aligning with scientific criteria as a hallmark symptom distinguishing it from chronic conditions like dementia.

Choice D reason: Inability to read relates to literacy or focal brain injury, not delirium. Delirium impairs global cognition—attention and memory—not specific skills like reading unless confusion interferes indirectly. Scientifically, this isn’t a core feature, as delirium’s impact is broader and transient.
