Nursing Elites

1. 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.

2. The healthcare provider is monitoring a client with left-sided heart failure. Which assessment finding indicates that the client's condition is worsening?

• A. Clear lung sounds
• B. Increased peripheral pulses
• C. Bibasilar crackles
• D. Improved activity tolerance

Correct answer: C

Rationale: Bibasilar crackles are abnormal lung sounds that indicate fluid accumulation in the lungs, a sign that left-sided heart failure is worsening. This finding suggests that the client's condition is deteriorating and requires prompt intervention to prevent further complications. Clear lung sounds (Choice A) are normal and would not indicate worsening heart failure. Increased peripheral pulses (Choice B) may be seen in conditions like anxiety or exercise, but not specifically in worsening left-sided heart failure. Improved activity tolerance (Choice D) would be a positive sign, not an indicator of worsening heart failure.

3. The LPN/LVN is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?

• A. Tall, peaked T waves
• B. ST-segment depression
• C. Prolonged P-R interval
• D. Widening of the QRS complex

Correct answer: B

Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG. Tall, peaked T waves are indicative of hyperkalemia, not hypokalemia. A prolonged P-R interval is more commonly associated with first-degree heart block. Widening of the QRS complex is typically seen in conditions like bundle branch blocks or ventricular tachycardia, not specifically in hypokalemia.

4. A client with a history of angina is scheduled for an exercise electrocardiography (ECG) test. The nurse should explain that the purpose of this test is to evaluate which factor?

• A. The heart's response to physical stress
• B. The client's overall physical fitness
• C. The presence of electrolyte imbalances
• D. The effectiveness of anti-anginal medications

Correct answer: A

Rationale: An exercise electrocardiography (ECG) test is used to evaluate the heart's response to physical stress. During the test, the heart's electrical activity is monitored while the client exercises, helping to identify any areas of ischemia or abnormal rhythms. This test helps healthcare providers assess the heart's function and detect any potential issues related to angina or other cardiac conditions. Choice B, the client's overall physical fitness, is incorrect because the test primarily focuses on the heart's response to stress rather than the client's general physical fitness. Choice C, the presence of electrolyte imbalances, is incorrect as this test is not specifically designed to evaluate electrolyte levels. Choice D, the effectiveness of anti-anginal medications, is incorrect as the main purpose of the test is to assess the heart's response to physical stress, not medication effectiveness.

5. A client with known coronary artery disease (CAD) begins to experience chest pain while getting out of bed. What action should the nurse take?

• A. Obtain a prescription for pain medication.
• B. Have the client stop and lie back down in bed.
• C. Report the complaint to the healthcare provider.
• D. Instruct the client to continue getting out of bed and into a chair.

Correct answer: B

Rationale: When a client with CAD experiences chest pain, it indicates myocardial ischemia. The nurse should have the client stop the activity and lie back down in bed to reduce the heart's oxygen demand, decrease myocardial workload, and prevent further ischemia. This action helps in improving blood flow to the heart and can potentially alleviate the chest pain. Option A is incorrect as pain medication should not be the initial action for chest pain in CAD. Option C is incorrect because the nurse should first intervene directly to address the chest pain. Option D is incorrect as continuing the activity can worsen the myocardial ischemia and chest pain.
