Which statement by a client taking nifedipine should lead to immediate follow-up by the nurse?

The statement regarding feeling a little stiff upon waking after starting nifedipine warrants immediate follow-up by the nurse because it may indicate the potential development of peripheral edema or a heightened effect of the medication on vascular smooth muscle. Nifedipine, a calcium channel blocker primarily used for hypertension and angina, can lead to side effects such as swelling due to vasodilation and fluid retention. Stiffness, particularly if it suggests musculoskeletal or systemic issues, could point toward complications that need assessment, especially if the stiffness is severe or progressive.

Frequent monitoring and patient education are essential in clients taking nifedipine, as they may experience various side effects ranging from mild discomfort to more serious reactions that require medical intervention. Assessing the specific nature of the stiffness or any accompanying symptoms is crucial to ensuring the client's well-being and managing medication effects appropriately.

In contrast, the other statements indicate more common or expected responses to the medication. Increased energy and decreased headaches suggest positive therapeutic effects, while mild swelling is a known side effect, but it doesn’t necessarily require immediate concern unless it is severe or accompanied by other alarming symptoms.
