ATI Pharmacology Quiz 25E Questions

Question 1 of 5

The patient has been started on warfarin (Coumadin) for deep vein thrombosis. The patient asks when the medication will break up the clots. The nurse's best response would be:

Correct Answer: A

Rationale: The correct answer is A because warfarin (Coumadin) is an anticoagulant that works to prevent blood clot formation and growth, rather than directly breaking down existing clots. Warfarin inhibits the production of certain clotting factors in the liver, making it less likely for the clot to enlarge or new clots to form. This process does not result in immediate clot dissolution, so the patient needs to be aware that the medication's primary goal is prevention rather than immediate clot breakdown.

Choices B, C, and D are incorrect as they provide inaccurate information regarding the mechanism and timeline of action of warfarin in clot dissolution, leading to potential misinformation and confusion for the patient.

Question 2 of 5

It is important that nurses ensure that their patients receive education regarding herbal products because:

Correct Answer: A

Rationale: The correct answer is A. Nurses should ensure patients receive education on herbal products because labeling may not always be reliable, and caution should be exercised. This is important as herbal products lack consistent regulation and may interact with medications.
Choice B is incorrect as herbal products are not strictly regulated by the FDA.
Choice C is incorrect as herbal products can have side effects and are not necessarily safe without a prescription.
Choice D is incorrect as effectiveness claims may not always be backed by scientific evidence.

Question 3 of 5

The patient is receiving enoxaparin (Lovenox) subcutaneously every 12 hours following knee replacement surgery. The patient is monitored for.

Correct Answer: D

Rationale: The correct answer is D: Signs and symptoms of bruising and bleeding. Enoxaparin is an anticoagulant that helps prevent blood clots. Monitoring for bruising and bleeding is crucial due to the increased risk of bleeding associated with anticoagulant therapy. Clotting at the incision site (
A) is not expected as enoxaparin prevents clot formation. Increased pain (
B) and gingival hyperplasia (
C) are not commonly associated with enoxaparin therapy. Monitoring for signs and symptoms of bruising and bleeding allows for early detection of any potential complications.

Question 4 of 5

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

Correct Answer: D

Rationale: Platelets are the correct answer because they play a crucial role in hemostasis. When a blood vessel is injured, platelets clump together and adhere to the vessel wall to form a plug, preventing further blood loss. This process is called primary hemostasis. White blood cells (
A) and antibodies (
B) are not directly involved in the initial clot formation. Red blood cells (
C) primarily carry oxygen and are not key players in hemostasis.
Therefore, platelets (
D) are the correct choice for initiating the process of hemostasis.

Question 5 of 5

A nurse is caring for a client who has a prescription for clopidogrel. Which of the following actions should the nurse plan to take?

Correct Answer: B

Rationale: The correct answer is B: Monitor the client for black, tarry stools. Clopidogrel is an antiplatelet medication that can increase the risk of bleeding, including gastrointestinal bleeding. Monitoring for black, tarry stools is crucial as it may indicate gastrointestinal bleeding, a serious side effect of the medication. Having suction equipment (choice
A) is not directly related to clopidogrel administration. Administering the medication with each meal (choice
C) is not necessary as clopidogrel can be taken with or without food. Initiation of contact precautions (choice
D) is not indicated for a client taking clopidogrel.
