Nursing Elites

1. A client who had a myocardial infarction (MI) two days ago reports chest pain radiating to the left arm. What should the nurse do immediately?

• A. Administer morphine
• B. Obtain an electrocardiogram (ECG)
• C. Apply oxygen via nasal cannula
• D. Administer sublingual nitroglycerin

Correct answer: B

Rationale: Obtaining an ECG is crucial in this situation because it helps in assessing for potential complications, such as a recurrent MI or ongoing ischemia. This diagnostic test provides valuable information to guide further interventions and treatment. Administering morphine, oxygen, or nitroglycerin may be necessary but obtaining an ECG takes precedence to evaluate the cardiac status and determine the appropriate course of action. Administering morphine without assessing the current cardiac status through an ECG can mask important diagnostic clues. Applying oxygen and administering nitroglycerin are supportive measures that can follow the ECG to address potential hypoxia and ischemic pain relief, respectively.

2. A client with a history of heart failure is prescribed metoprolol (Lopressor). The nurse should monitor the client for which common side effect of this medication?

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

Correct answer: B

Rationale: Metoprolol is a beta-blocker commonly used in heart failure to reduce blood pressure. One of the common side effects of metoprolol is hypotension, which can lead to dizziness, lightheadedness, and even fainting. Therefore, monitoring for hypotension is essential to prevent adverse effects and ensure patient safety. Choices A, C, and D are incorrect. Tachycardia is not a common side effect of metoprolol, as it actually reduces heart rate. Hypertension is also not a common side effect of this medication, as it is intended to lower blood pressure. Hyperglycemia is not a typical side effect of metoprolol.

3. The healthcare provider is reviewing the medication orders for a client with angina pectoris. Which medication is typically prescribed to prevent angina attacks?

• A. Aspirin
• B. Nitroglycerin
• C. Atenolol
• D. Simvastatin

Correct answer: B

Rationale: Nitroglycerin is the medication typically prescribed to prevent angina attacks. It works by dilating blood vessels, increasing blood flow, and reducing the heart's workload, hence relieving angina symptoms. Aspirin is often used to prevent blood clots, not specifically to prevent angina attacks. Atenolol is a beta-blocker used to manage high blood pressure and chest pain but is not typically prescribed to prevent angina attacks. Simvastatin is a statin medication primarily used to lower cholesterol levels and is not indicated for preventing angina attacks.

4. The client is receiving anticoagulant therapy for atrial fibrillation. Which laboratory test should be monitored to determine the effectiveness of the therapy?

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

Correct answer: A

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of anticoagulant therapy in clients with atrial fibrillation. These tests help ensure that the client is within the therapeutic range and are commonly used to assess the clotting ability of the blood. Monitoring PT and INR levels allows healthcare providers to adjust anticoagulant dosages as needed to prevent complications such as bleeding or thrombosis. Activated partial thromboplastin time (aPTT) is more commonly used to monitor heparin therapy, not anticoagulant therapy for atrial fibrillation. Platelet count assesses the number of platelets in the blood and is not a direct indicator of anticoagulant therapy effectiveness. Erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is not used to monitor anticoagulant therapy.

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

• A. Store the medication in a cool, dry place.
• B. Take the medication as directed by the healthcare provider.
• C. Take the medication 30 minutes before meals.
• D. Take the medication at the first sign of chest pain.

Correct answer: D

Rationale: Instructing the client to take nitroglycerin at the first sign of chest pain is crucial for immediate relief of angina symptoms. Nitroglycerin is a fast-acting medication that helps dilate blood vessels, improving blood flow to the heart muscle. Therefore, prompt administration at the onset of chest pain is essential to alleviate anginal episodes effectively. Choices A, B, and C are incorrect because storing the medication properly, taking it as directed, or before meals are not specific instructions for managing acute anginal episodes, which require immediate action for symptom relief.
