Nursing Elites

1. The nurse is administering a beta blocker to a client with a heart rate of 50 bpm. What is the priority action?

• A. Hold the beta blocker and notify the healthcare provider.
• B. Administer the beta blocker as ordered.
• C. Decrease the dose of the beta blocker.
• D. Monitor the client’s heart rate and reassess in 30 minutes.

Correct answer: A

Rationale: The correct action is to hold the beta blocker and notify the healthcare provider. A heart rate of 50 bpm is already low, and beta blockers can further decrease the heart rate, potentially causing adverse effects like bradycardia or heart block. Administering the beta blocker as ordered (Choice B) can exacerbate the low heart rate. Decreasing the dose of the beta blocker (Choice C) may not be sufficient to address the potential harm. Monitoring the client’s heart rate and reassessing in 30 minutes (Choice D) may delay necessary interventions if the heart rate drops further. Therefore, the priority is to hold the medication and seek guidance from the healthcare provider.

2. What is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle?

• A. Coronary artery disease (CAD)
• B. Atherosclerosis
• C. Stroke
• D. Peripheral artery disease

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle and an increased risk of heart attack. Choice B, Atherosclerosis, is a related condition involving the buildup of fats, cholesterol, and other substances in and on the artery walls, but it is not specific to the coronary arteries. Choices C and D, Stroke and Peripheral artery disease, respectively, involve different arteries and conditions, not directly related to the narrowing or blockage of the coronary arteries.

3. What procedure uses a balloon to open narrowed or blocked blood vessels in the heart?

• A. Angioplasty
• B. Coronary artery bypass graft
• C. Stent placement
• D. Valve replacement

Correct answer: A

Rationale: The correct answer is Angioplasty. Angioplasty is a procedure that involves using a balloon to open narrowed or blocked blood vessels in the heart, thereby improving blood flow. This choice is correct because it directly matches the description provided in the question. Choices B, C, and D are incorrect because they involve different procedures: Bypass graft is a surgical procedure to redirect blood flow, stent placement involves inserting a mesh tube to keep an artery open, and valve replacement is the surgical replacement of a heart valve.

4. What is the abnormal accumulation of fluid in the pleural space, often associated with infections or malignancies?

• A. Pleural effusion
• B. Pneumothorax
• C. Pulmonary edema
• D. Atelectasis

Correct answer: A

Rationale: The correct answer is A, pleural effusion. Pleural effusion is the accumulation of excess fluid between the layers of the pleura outside the lungs, often caused by infections, cancer, or other diseases. Pneumothorax (choice B) is the presence of air in the pleural space, not fluid. Pulmonary edema (choice C) is the accumulation of fluid in the lungs' air sacs and tissue, not in the pleural space. Atelectasis (choice D) is the collapse or closure of a lung resulting in reduced or absent gas exchange.

5. Which term refers to the relaxation phase of the heart, during which the chambers fill with blood?

• A. Diastole
• B. Systole
• C. Refractoriness
• D. Automaticity

Correct answer: A

Rationale: The correct answer is A, Diastole. Diastole is the phase of the cardiac cycle when the heart muscles relax, allowing the chambers to fill with blood. Choice B, Systole, is incorrect as systole is the contraction phase of the heart when blood is pumped out of the chambers. Choice C, Refractoriness, refers to a period during which the heart muscle is unresponsive to stimuli. Choice D, Automaticity, relates to the heart's ability to generate its own electrical impulses.
