Question

Which lab would the nurse monitor for the client taking clopidogrel?

Answers

  1. PT
    • Rationale:

      This answer is not correct because PT measures the client’s ability to form a blood clot. It can show the effectiveness of a medication prescribed for the prevention of blood clots, such as warfarin.

  2. PTT
    • Rationale:

      This answer is not correct because PTT is used to monitor heparin. PTT measures how long it takes for the blood to clot while taking heparin.

  3. INR
    • Rationale:

      This answer is not correct because INR is used to monitor clients who are taking warfarin. It is a calculation based on the PT.

  4. Platelet
    • Rationale:

      This answer is correct because clopidogrel is an antiplatelets. A client taking an antiplatelet will need to have their platelet count monitored. Other antiplatelets include aspirin, ticagrelor, and prasugrel.

Overview

Clopidogrel stops the blood cells from clumping together. It is an antiplatelet drug and for this reason platelets should be monitored.

Explanation

Learning Outcomes

Clopidogrel is an antiplatelet medication. Antiplatelets work by making the blood less sticky so that it does not clump together and form clots. Low platelets can result in bleeding. For this reason, it is important to monitor the platelet counts for clients on antiplatelet therapy. PT measures the client’s ability to form a blood clot. It can show the effectiveness of a medication prescribed for the prevention of blood clots, such as warfarin. INR is used to monitor clients who are taking warfarin. It is a calculation based on the PT. PTT is used to monitor heparin. PTT measures how long it takes for the blood to clot while taking heparin.

Test Taking Tip

If the student knows the drug class of clopidogrel, this question will be answered correctly. Know the drug classes and the differences between antiplatelets and anticoagulants.
