The nurse is caring for a client taking clopidogrel. For which adverse effect should the nurse monitor?

A. Flu-like symptoms: Clopidogrel can cause adverse effects related to platelet inhibition and immune response, including flu-like symptoms such as fever, malaise, and body aches. Monitoring for these symptoms helps identify early reactions that may require intervention or discontinuation of the medication. B. Constipation: Constipation is not commonly associated with clopidogrel use. While gastrointestinal discomfort may occur in some clients, it is not a primary adverse effect to monitor when administering this antiplatelet therapy. C. Nervousness: Nervousness or anxiety is not a recognized adverse effect of clopidogrel. Monitoring for neurological or psychological changes is not typically necessary for this medication unless other comorbidities exist. D. Hypertension: Clopidogrel does not usually cause elevated blood pressure. Monitoring blood pressure is part of routine assessment but is not specifically related to clopidogrel therapy or its adverse effects.
