1. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

2. A client with HIV-1 infection is prescribed zidovudine as part of antiretroviral therapy. The nurse should monitor the client for which of the following adverse effects of this medication?

• A. Cardiac dysrhythmia
• B. Metabolic alkalosis
• C. Renal failure
• D. Aplastic anemia

Correct answer: D

Rationale: Corrected Rationale: Zidovudine is associated with the development of aplastic anemia, a serious adverse effect characterized by bone marrow suppression. Regular monitoring is essential to detect this side effect early and prevent complications. Cardiac dysrhythmia, metabolic alkalosis, and renal failure are not commonly associated with zidovudine use, making them incorrect choices for adverse effects of this medication.

3. A healthcare professional is caring for a client who is receiving heparin therapy. Which of the following laboratory tests should the healthcare professional monitor to evaluate the therapeutic effect of heparin?

• A. PT/INR
• B. Platelet count
• C. aPTT
• D. WBC count

Correct answer: C

Rationale: The correct test to monitor the therapeutic effect of heparin is the activated partial thromboplastin time (aPTT). Heparin's action is to prolong the clotting time, and aPTT reflects this effect. Monitoring aPTT helps ensure that the client is within the therapeutic range to prevent clot formation while minimizing the risk of bleeding complications. PT/INR is used to monitor warfarin therapy, platelet count assesses for potential thrombocytopenia, and WBC count evaluates for signs of infection or inflammation, not the therapeutic effect of heparin.

4. A client is being educated about Fluticasone for treating Perennial Rhinitis. Which statement by the client indicates an understanding of the teaching?

• A. I should use the spray every 4 hours while I am awake.
• B. It can take as long as 3 weeks before the medication takes maximum effect.
• C. This medication can also be used to treat motion sickness.
• D. I can use this medication when my nasal passages are blocked.

Correct answer: B

Rationale: Correct! While the client may experience some benefits of Fluticasone within a few hours, the maximum effects may not be seen until up to 3 weeks of consistent use. This understanding is important to manage expectations and ensure the client uses the medication effectively for the treatment of Perennial Rhinitis.

5. A client has a new prescription for Loperamide. Which of the following instructions should the nurse include?

• A. Take the medication with a full glass of water.
• B. Avoid activities that require alertness.
• C. Increase your intake of high-fiber foods.
• D. Expect your stools to be black and tarry.

Correct answer: B

Rationale: The correct answer is B. Loperamide can cause drowsiness and dizziness, so clients should avoid activities that require alertness until they know how the medication affects them. Taking the medication with a full glass of water can help with absorption. Increasing intake of high-fiber foods is not directly related to Loperamide. Black, tarry stools are not expected side effects of this medication, so informing the client to expect this is incorrect.
