Question

Which statement by the nurse properly explains the action of clopidogrel to a nursing student about a client taking this medication after stent placement?

Answers

  1. "Clopidogrel is the antidote for heparin treatment."
    • Rationale:

      This answer is not correct because clopidogrel is not the antidote for heparin. Protamine sulfate is the antidote for heparin. Clopidogrel is an oral antiplatelet.

  2. "Clopidogrel is used to eliminate existing clots."
    • Rationale:

      This answer is not correct because clopidogrel does not have the action of eliminating clots like thrombolytics do. Instead, clopidogrel is an antiplatelet, which helps prevent platelet aggregation, thus, increasing bleeding time.

  3. "Clopidogrel is prescribed for prevention of erythrocytosis"
    • Rationale:

      This answer is not correct because clopidogrel does not prevent erythrocytosis, the action of increasing the number of red blood cells. Instead, clopidogrel is associated with prevention of platelet aggregation.

  4. "Clopidogrel is given for prevention of platelet aggregation"
    • Rationale:

      This answer is correct because clopidogrel is an antiplatelet. This medication prevents platelet aggregation, thus increasing bleeding time. Clopidogrel is used prophylactically for prevention of complications following myocardial infarction, coronary stents, or stroke.

Overview

Clopidogrel is an antiplatelet medication used to prevent complications after a myocardial infarction, coronary stent placement, or stroke. The client should be monitored carefully for the side effect of bleeding.

Explanation

Learning Outcomes

Clopidogrel is an oral medication which inhibits the aggregation of platelets during the clotting process. This prolongs the client’s bleeding time. Therefore, the nurse should monitor and teach the client to monitor for bleeding. This includes assessment watching for bleeding gums and rectal bleeding or blood in the stool. Clopidogrel is commonly used prophylactically for prevention of complications following myocardial infarction, coronary stents, or stroke.

Test Taking Tip

Monitor questions that you answer with an educated guess or changed your answer from the first option you selected. Usually your first answer is correct and should not be changed without reason.
