A nurse is collecting data from a group of clients. Which of the following images indicates a client the nurse should identify as exhibiting clubbing  of the fingers?

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.

• Allergies: The client has a documented allergy to penicillin, and cefazolin is a first-generation cephalosporin. Cephalosporins have a similar beta-lactam structure to penicillins, and there is a potential risk of cross-reactivity. Administering cefazolin without provider clearance could result in a severe allergic reaction or anaphylaxis.
• Temperature: Although the client's temperature is elevated at 39.3° C (102.8° F), this is an expected finding in pneumonia and does not need to be reported before antibiotic administration. In fact, treating the infection may help reduce the fever.
• Chest x-ray: The chest x-ray showing left lower lobe density is consistent with a diagnosis of pneumonia and supports the need for antibiotic treatment. This finding confirms the infection in the lungs and guides the choice of antibiotic therapy. It is not a reason to withhold the prescribed medication but rather a justification for it.
• WBC count: The client’s WBC count is elevated at 16,000/mm³, which is typical in bacterial infections like pneumonia. It reflects the body's immune response and further supports the need for antibiotics rather than delaying them.
