Quick answerStop the proxy dosing through teaching and assess how sedated the client is.
Why this is correctThe pump is safe because a sedated client cannot self-administer. When someone else presses the button, that limit disappears and respiratory depression can develop, so the teaching and the sedation check happen now.
Easy analogy or mental pictureIt is like disabling a dead-man switch on a machine. The comparison explains why the safeguard matters and does not suggest the analgesia itself is inappropriate.
Memory hookThe button belongs to the client alone.NCLEX decision ruleWhen proxy dosing is discovered, stop it and assess sedation and respiratory status. Prescription changes follow the assessment rather than substitute for it.
Why the other choices are wrongChanging the dose, documenting for later, and removing the pump are each plausible follow-ups, but none of them stops the unsafe practice at the bedside right now.
