1. A client is receiving heparin therapy. Which of the following laboratory tests should be monitored to evaluate the effectiveness of the therapy?

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the most appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works on the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps assess its anticoagulant effect. Therapeutic levels of aPTT for clients on heparin therapy are typically 1.5 to 2.5 times the control value. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, which acts on the extrinsic pathway of the coagulation cascade. Complete blood count (CBC) is not specific for monitoring the effectiveness of heparin therapy.

2. A nurse is providing teaching to a client who has a new prescription for warfarin. Which of the following statements should the nurse include?

Correct answer: B

Rationale: The correct answer is B: 'Report any signs of bleeding.' When a patient is prescribed warfarin, it is essential to monitor for signs of bleeding as warfarin is an anticoagulant that increases the risk of bleeding. Choices A, C, and D are incorrect. Avoid using a soft toothbrush is not directly related to warfarin therapy, increasing the intake of leafy green vegetables can interfere with warfarin's effectiveness due to its vitamin K content, and taking warfarin with food is unnecessary as it can be taken with or without food.

3. The client has been prescribed warfarin (Coumadin) and is being educated about dietary restrictions. Which food should the client be advised to avoid or eat in consistent amounts?

Correct answer: B

Rationale: Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin. It is important for clients taking warfarin to maintain consistent levels of vitamin K intake to ensure the medication works properly. Foods rich in vitamin K, such as spinach, can counteract the effects of warfarin, leading to potential complications. Therefore, clients on warfarin are advised to either avoid or consume vitamin K-rich foods, like spinach, in consistent amounts to maintain the medication's efficacy. Bananas, oranges, and yogurt are not high in vitamin K and do not significantly impact the effectiveness of warfarin, making them safe options for clients taking this medication.

4. The client has been prescribed atorvastatin (Lipitor) for hyperlipidemia. Which instruction should the nurse provide to the client?

Correct answer: B

Rationale: The correct instruction for the nurse to provide to the client prescribed atorvastatin (Lipitor) for hyperlipidemia is to avoid drinking grapefruit juice while taking this medication. Grapefruit juice can interfere with the metabolism of atorvastatin, leading to an increased risk of side effects. It is crucial for the client to adhere to this instruction to ensure the effectiveness and safety of the treatment. Choices A, C, and D are incorrect because taking the medication with breakfast, increasing dietary fiber intake, and avoiding foods high in potassium are not specific instructions related to atorvastatin therapy for hyperlipidemia.

5. The client has angina pectoris and is prescribed nitroglycerin patches. What instruction should the nurse provide to the client?

Correct answer: B

Rationale: The correct instruction for the nurse to provide to the client is to apply the nitroglycerin patch to a different site each time to prevent skin irritation. Rotating the application site is crucial to prevent skin irritation and ensure consistent absorption of the medication. Applying the patch to the same site can lead to skin irritation and decreased effectiveness. Removing the patch before going to bed is not necessary, as the patch can typically be worn for a specific duration. Cutting the patch in half if experiencing headaches is not recommended and can alter the dose of the medication.
