Correct Answer is B
Explanation
Choice A rationale: Dry mouth is a known side effect of clonidine, and denying this information would be inaccurate.
Choice B rationale: Providing strategies to alleviate the side effect, such as offering hard candy or gum, is a proactive approach to managing the dry mouth without discontinuing the medication.
Choice C rationale: Stopping antihypertensive medication abruptly can lead to rebound hypertension, and the nurse should not encourage discontinuation without consulting the healthcare provider.
Choice D rationale: Adjusting the dose of clonidine should be done under the guidance of a healthcare provider; self-adjustment without professional input is not advisable.
