A pediatric patient receiving IV morphine begins to experience pruritus. What is the most appropriate nursing intervention?

Choice A reason: Administering a PRN antihistamine is a standard approach to managing opioid-induced pruritus, which is a common side effect. Considering opioid rotation may also help reduce side effects while maintaining pain control. Choice B reason: Increasing the opioid dose may worsen pruritus and is not an appropriate response to this adverse effect. It does not address the underlying histamine release. Choice C reason: Switching to a non-opioid regimen may be considered if pruritus is severe and persistent, but it is not the first-line intervention. Pain control must be maintained, and alternatives should be evaluated carefully. Choice D reason: Discontinuing the opioid immediately may lead to unmanaged pain. Unless pruritus is severe or accompanied by other allergic symptoms, this is not the most appropriate initial action.
