A nurse is reinforcing teaching about the side effects of metoprolol. Which of the following client statements indicates an understanding of the teaching?

A. "I should limit my intake of leafy green vegetables.": Limiting leafy green vegetables is associated with warfarin therapy because of their vitamin K content. It is not relevant to metoprolol, which primarily affects the cardiovascular system and does not interact significantly with dietary vitamin K. B. "I may experience loss of taste.": Loss of taste is not a common side effect of metoprolol. Metoprolol is more associated with cardiovascular side effects such as bradycardia, hypotension, and dizziness rather than alterations in taste perception. C. "I need to be careful when standing up from bed.": This is correct because metoprolol can cause orthostatic hypotension, leading to dizziness or lightheadedness upon standing. Clients are advised to rise slowly from a lying or seated position to reduce the risk of falls and fainting. D. "I should expect some weight loss.": Metoprolol is more commonly associated with weight gain or no significant weight change rather than weight loss. Clients taking beta-blockers sometimes experience fluid retention or a slowed metabolism, leading to modest weight gain.
