A patient on an ACE inhibitor reports a dry cough. What is the most appropriate nursing response?

Choice A rationale While a dry cough is a common side effect of ACE inhibitors, it should not be simply dismissed. The cough is caused by the accumulation of bradykinin, a substance that is normally degraded by the enzyme that ACE inhibitors block. This cough can be very bothersome to patients, and in some cases, can progress and may warrant a change in medication. Choice B rationale Increasing fluid intake is a supportive measure for many types of coughs, but it does not address the underlying pharmacological cause of an ACE inhibitor-induced cough. The cough is a direct result of bradykinin accumulation in the lungs, and simply drinking more water will not reduce this level or resolve the cough. The appropriate action involves addressing the root cause. Choice C rationale The cough associated with ACE inhibitors is a known side effect that occurs due to the accumulation of bradykinin. This side effect is often a significant reason for discontinuation. The most appropriate nursing action is to report the finding to the healthcare provider so they can evaluate the patient and consider alternative therapies, such as an angiotensin II receptor blocker (ARB), which does not affect bradykinin levels. Choice D rationale Discontinuing the medication immediately is not the appropriate action. While a cough can be bothersome, it is not a life-threatening emergency. Abruptly stopping the medication, especially in a patient with a history of hypertension or heart failure, could lead to a sudden and dangerous increase in blood pressure or a worsening of their underlying condition. The decision to discontinue or change medication must be made by the healthcare provider.
