Nursing Elites

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

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Complete blood count (CBC)

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. The healthcare provider is caring for a client with hypertension who is receiving a beta blocker. The provider should monitor for which potential side effect?

• A. Tachycardia
• B. Bradycardia
• C. Hypertension
• D. Hyperglycemia

Correct answer: B

Rationale: Corrected Rationale: Beta blockers are medications that can cause bradycardia by slowing down the heart rate. It is essential to monitor for this side effect in clients receiving beta blockers, as it can lead to serious complications such as decreased cardiac output and hypotension. Choices A, C, and D are incorrect because beta blockers are not expected to cause tachycardia (fast heart rate), hypertension (high blood pressure), or hyperglycemia (high blood sugar levels).

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

• A. Monitor blood pressure daily.
• B. Take the medication with food.
• C. Increase intake of potassium-rich foods.
• D. Avoid consuming grapefruit juice.

Correct answer: A

Rationale: The correct answer is to instruct the client to monitor their blood pressure daily. Lisinopril is known to cause hypotension, so monitoring blood pressure regularly is essential to detect any potential issues early on. Choice B is incorrect as lisinopril is usually taken on an empty stomach. Choice C is incorrect as lisinopril can increase potassium levels, so additional intake of potassium-rich foods may lead to hyperkalemia. Choice D is incorrect because grapefruit juice can interact with lisinopril, leading to adverse effects.

4. The LPN/LVN is reinforcing discharge instructions to a client who has been prescribed nitroglycerin sublingual tablets for angina. Which statement by the client indicates a need for further teaching?

• A. I will keep my nitroglycerin tablets in the original glass bottle.
• B. I will sit or lie down when I take a nitroglycerin tablet.
• C. I will take a nitroglycerin tablet every 5 minutes if chest pain persists, up to a total of 3 tablets.
• D. I can swallow the nitroglycerin tablet with a glass of water if it does not dissolve quickly.

Correct answer: D

Rationale: The correct answer is D. Nitroglycerin sublingual tablets should not be swallowed; they must dissolve under the tongue to be effective. Choice A is correct as nitroglycerin tablets should be stored in their original glass container to prevent degradation. Choice B is correct as sitting or lying down when taking a nitroglycerin tablet helps prevent dizziness or fainting due to a sudden drop in blood pressure. Choice C is correct as taking a nitroglycerin tablet every 5 minutes for a maximum of 3 tablets is the correct protocol for managing angina symptoms.

5. In monitoring the effectiveness of warfarin therapy for a client with a history of atrial fibrillation, which laboratory value should the nurse monitor?

• A. Activated partial thromboplastin time (aPTT)
• B. Prothrombin time (PT) and international normalized ratio (INR)
• C. Platelet count
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are crucial laboratory values to monitor the effectiveness of warfarin therapy in clients with atrial fibrillation. These values help ensure that the client is within the therapeutic range and that the anticoagulant effect of warfarin is appropriate. Monitoring aPTT, platelet count, or ESR is not directly related to assessing the effectiveness of warfarin therapy in these cases.
