The patient requests information on alternative treatments for her arthritis. The nurse provides the patient with information on which of the following supplements?

A. Nausea and vomiting: Nausea and vomiting can occur with epoetin alfa, but it's not the most common side effect.

B. Orthostatic hypotension: This is not a common side effect of epoetin alfa. Orthostatic hypotension is a decrease in blood pressure upon standing.

C. Hypertension: Epoetin alfa stimulates the production of red blood cells. When the red blood cell count increases too quickly, it can lead to increased blood pressure, which is the most common adverse effect.

D. Dizziness: Dizziness can occur with epoetin alfa, but it's less common than hypertension.

A. Constipation: Constipation is not a commonly reported adverse effect of clopidogrel (Plavix). Clopidogrel is an antiplatelet medication that works by inhibiting platelet aggregation, and gastrointestinal effects such as constipation are not typically associated with its use.

B. Bruising: This is a correct answer. Bruising is a known adverse effect of clopidogrel. As an antiplatelet medication, clopidogrel inhibits platelet aggregation, which can increase the risk of bleeding and bruising.

C. Rash: Rash is a potential adverse effect of clopidogrel, although it is not as common as other side effects such as bruising or gastrointestinal symptoms. Patients taking clopidogrel should be monitored for signs of allergic reactions, including rash, which may indicate the need for further evaluation or discontinuation of the medication.

D. Headache: Headache is not a commonly reported adverse effect of clopidogrel. While some patients may experience headache while taking clopidogrel, it is not considered a frequent or significant side effect of the medication.

E. Diarrhea: Diarrhea is not a commonly reported adverse effect of clopidogrel. Gastrointestinal symptoms such as diarrhea are not typically associated with clopidogrel use, although some patients may experience gastrointestinal upset as a side effect of antiplatelet therapy.
