1. Which term describes an abnormal heartbeat that can be either too fast or too slow?

• A. Arrhythmia
• B. Bradycardia
• C. Tachycardia
• D. Conductivity

Correct answer: A

Rationale: The correct answer is A: Arrhythmia. Arrhythmia is a broad term that refers to any irregularity in the heart's rhythm, which can manifest as a heartbeat that is too fast (tachycardia), too slow (bradycardia), or irregular. Choice B, Bradycardia, specifically denotes a slow heart rate, while choice C, Tachycardia, refers to a fast heart rate. Choice D, Conductivity, is not the correct term to describe an abnormal heartbeat characterized by speed irregularities.

2. Which artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart?

• A. Left anterior descending artery
• B. Left circumflex artery
• C. Posterior descending artery
• D. Aortic artery

Correct answer: A

Rationale: The correct answer is the Left anterior descending artery. This artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart. The Left circumflex artery (choice B) supplies the lateral and posterior walls of the left ventricle, the posterior descending artery (choice C) supplies the inferior part of the heart, and the aortic artery (choice D) is not a specific coronary artery.

3. What is the condition where a blood clot blocks an artery in the lungs, causing shortness of breath, chest pain, and other symptoms?

• A. Pulmonary embolism
• B. Pneumothorax
• C. Pleural effusion
• D. Aneurysm

Correct answer: A

Rationale: The correct answer is Pulmonary embolism. Pulmonary embolism occurs when a blood clot blocks an artery in the lungs, leading to symptoms like shortness of breath and chest pain. This condition is life-threatening and requires prompt treatment. Choices B, C, and D are incorrect as they refer to different medical conditions: Pneumothorax is a collapsed lung, Pleural effusion is an abnormal accumulation of fluid around the lungs, and an Aneurysm is a bulge in a blood vessel.

4. What is the accumulation of fatty deposits along the walls of arteries, leading to reduced blood flow?

• A. Atherosclerosis
• B. Arteriosclerosis
• C. Aneurysm
• D. Thrombosis

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It refers to the buildup of fatty deposits (plaque) along the inner walls of arteries, narrowing the blood vessels and reducing blood flow. This condition can lead to serious complications such as heart attacks or strokes. Arteriosclerosis (choice B) is a broader term that refers to the thickening and hardening of the arterial walls. While related, it is not as specific as atherosclerosis in describing the fatty deposit accumulation. Aneurysm (choice C) is the abnormal bulging of an artery wall that can rupture and cause internal bleeding, not specifically related to fatty deposits. Thrombosis (choice D) is the formation of a blood clot within a blood vessel, which can obstruct blood flow, but it is not directly related to the accumulation of fatty deposits.

5. The nurse is administering an ACE inhibitor to a client. What is the most common side effect?

• A. Cough
• B. Dizziness
• C. Hypotension
• D. Hyperkalemia

Correct answer: A

Rationale: The correct answer is A: Cough. Cough is a well-known side effect of ACE inhibitors due to an increase in bradykinin levels. This irritating cough can be bothersome to clients and should be monitored. Choice B, Dizziness, is not the most common side effect of ACE inhibitors. While ACE inhibitors can cause hypotension (Choice C), cough is more prevalent. Hyperkalemia (Choice D) is a possible side effect of ACE inhibitors but is less common compared to cough.
