Nursing Elites

1. 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.

2. A client has a new prescription for nitroglycerin. Which of the following instructions should the nurse include in the discharge teaching?

• A. Store the medication in a cool, dark place.
• B. Take the medication at bedtime.
• C. Take the medication on an empty stomach.
• D. Take the medication at the first sign of chest pain.

Correct answer: D

Rationale: The correct instruction to include in the discharge teaching for a client with a new prescription for nitroglycerin is to take the medication at the first sign of chest pain. Nitroglycerin is a vasodilator that helps relax blood vessels, increasing blood flow to the heart muscle and reducing the workload of the heart. Taking it at the onset of chest pain helps alleviate angina symptoms quickly and effectively. Storing the medication in a cool, dark place (Choice A) is not a critical instruction for this medication. Taking the medication at bedtime (Choice B) or on an empty stomach (Choice C) is not relevant to the administration of nitroglycerin for angina relief.

3. A client with a diagnosis of acute myocardial infarction (MI) is receiving thrombolytic therapy. The nurse monitors the client for which potential complication associated with this therapy?

• A. Hypertension
• B. Bleeding
• C. Hyperkalemia
• D. Hypoglycemia

Correct answer: B

Rationale: Thrombolytic therapy is associated with an increased risk of bleeding due to its mechanism of action in dissolving blood clots. Therefore, the nurse should closely monitor the client for any signs of hemorrhage, such as unexplained bruising, bleeding gums, or blood in the urine or stools. Hypertension is not a common complication of thrombolytic therapy. Hyperkalemia and hypoglycemia are also not typically associated with this therapy.

4. The nurse is preparing a client for discharge after a myocardial infarction (MI). Which instruction is most important for the nurse to reinforce with the client?

• A. Avoid engaging in sexual activity for at least 6 weeks.
• B. Engage in moderate physical activity daily.
• C. Take prescribed medications even if you feel well.
• D. Return to work only when medically cleared.

Correct answer: C

Rationale: The most critical instruction for a client after a myocardial infarction is to continue taking prescribed medications even if they feel well. This is essential in preventing another myocardial infarction or other complications. Discontinuing medications prematurely can be detrimental to the client's recovery and may increase the risk of further cardiovascular events. Choices A, B, and D are incorrect because engaging in sexual activity, physical activity, or returning to work are important aspects of the client's recovery, but not as crucial as ensuring medication compliance to prevent further cardiac issues.

5. A client has a new prescription for heparin. Which of the following laboratory results should be monitored to evaluate the effectiveness of the medication?

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

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the laboratory result that should be monitored to evaluate the effectiveness of heparin. Heparin works by prolonging the aPTT, and monitoring this parameter helps ensure the medication's effectiveness and safety in preventing clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor the effectiveness of warfarin, another anticoagulant. Platelet count is essential to assess platelet function and clotting disorders, but it is not specifically used to monitor heparin therapy.
