A nurse is administering an enteric-coated medication to an adult client who has right-sided weakness and is having difficulty swallowing tablet. Which of the following actions should the nurse take?

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.

A. Fidelity: Fidelity refers to the responsibility to maintain trust and uphold promises made to clients. While important, the core issue in this case is not about fulfilling prior commitments but rather about responding truthfully to a direct question from the adolescent regarding their medical condition.

B. Authority: Authority is the recognized power to make decisions or enforce obedience, typically within a professional or legal framework. In this situation, the ethical dilemma is not related to decision-making power but centers on the nurse's obligation to provide honest communication.

C. Justice: Justice emphasizes fairness and equitable treatment of all clients in healthcare settings. Although justice is critical to ethical practice, the specific challenge here involves answering truthfully when asked about a relapse, rather than issues of equitable treatment or distribution of care.

D. Veracity: Veracity demands honesty and transparency when communicating with clients about their health. When the adolescent directly questions the nurse about their medical status, veracity obligates the nurse to provide truthful and accurate information, respecting the client's right to know.
