Which of the following clump and adhere to the wall of the injured blood vessel to begin the process of hemostasis?

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.

A. Have suction equipment at the bedside. Clopidogrel is an antiplatelet medication that inhibits blood clot formation. While it does not typically increase the risk of bleeding to the extent that requires constant suctioning, it's prudent to have suction equipment readily available for any patient who may be at risk of bleeding due to their underlying condition or concurrent medications. However, the administration of clopidogrel alone does not necessitate the need for constant suctioning.

B. Monitor the client for black, tarry stools. This is the correct answer. Clopidogrel, like other antiplatelet medications, increases the risk of bleeding, including gastrointestinal bleeding. Black, tarry stools can indicate gastrointestinal bleeding, which can be a serious complication of clopidogrel therapy. Therefore, monitoring for this symptom is essential for early detection of potential bleeding complications.

C. Administer the medication with each meal. Clopidogrel can be administered with or without food, as it is not significantly affected by food intake. However, there is no specific recommendation to administer it with meals. The timing of administration may vary based on the prescriber's instructions or patient preferences, but it does not need to be consistently administered with meals.

D. Initiate contact precautions. Clopidogrel therapy does not require contact precautions. Contact precautions are typically implemented for patients with contagious infections that spread via direct or indirect contact. Clopidogrel does not pose a risk of transmission to others and does not warrant contact precautions.
