While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. INR
- C. aPTT
- D. Platelet count
Correct Answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation.

A healthcare provider is providing discharge instructions to a client who has a new prescription for Warfarin. Which of the following over-the-counter medications should the provider instruct the client to avoid?
- A. Acetaminophen
- B. Ibuprofen
- C. Diphenhydramine
- D. Loratadine
Correct Answer: B
Rationale: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of bleeding when taken with Warfarin due to its antiplatelet effects. The combination of Warfarin, an anticoagulant, and NSAIDs can potentiate the risk of bleeding complications. Clients on Warfarin should avoid NSAIDs and opt for alternative pain relief options to minimize the risk of adverse effects.
A client has a new prescription for Atenolol. Which of the following instructions should be included by the healthcare provider?
- A. Take this medication in the morning.
- B. Monitor your heart rate regularly.
- C. Avoid foods high in potassium.
- D. Increase your fluid intake.
Correct Answer: B
Rationale: Atenolol is a beta-blocker that can cause bradycardia, leading to a decreased heart rate. Monitoring heart rate regularly is essential to detect any significant decreases promptly and seek medical attention. While other choices may be relevant to the client's overall health, monitoring heart rate is the priority instruction due to the nature of Atenolol's effects.

A client has a new prescription for hydrochlorothiazide. The client should monitor for which of the following adverse effects?
- A. Hyponatremia
- B. Ototoxicity
- C. Hypoglycemia
- D. Hyperkalemia
Correct Answer: A
Rationale: Hyponatremia is a potential adverse effect of hydrochlorothiazide due to its diuretic action. Hydrochlorothiazide is a thiazide diuretic that can cause sodium and water loss, potentially leading to hyponatremia. Monitoring for symptoms such as weakness, confusion, and muscle cramps can help detect hyponatremia early.
