Cardiovascular System Exam

1. What is a condition characterized by episodes of severe, acute shortness of breath, often occurring at night?

Correct answer: A

Rationale: Paroxysmal nocturnal dyspnea is the correct answer. It is characterized by sudden episodes of severe shortness of breath during sleep, often waking the individual. Choice B, Sleep apnea, involves pauses in breathing during sleep but does not usually present with acute shortness of breath. Choice C, Orthopnea, refers to shortness of breath that occurs when lying flat and is relieved by sitting up. Choice D, Dyspnea, is a general term for difficult or labored breathing and does not specifically describe acute episodes at night.

2. Which procedure is used to remove excess fluid or air from the pleural space, helping to relieve pressure on the lungs?

Correct answer: A

Rationale: The correct answer is Thoracentesis. Thoracentesis is a procedure specifically designed to remove excess fluid or air from the pleural space in the chest. This process helps to relieve pressure on the lungs and improve breathing. Bronchoscopy (Choice B) is a procedure used to visualize the airways and diagnose lung conditions, not to remove fluid from the pleural space. Chest X-ray (Choice C) is an imaging test that provides a picture of the structures inside the chest, including the lungs, heart, and bones. Arterial blood gas (ABG) test (Choice D) is a blood test that measures the levels of oxygen and carbon dioxide in the blood, providing information about how well the lungs are working, but it does not involve removing excess fluid or air from the pleural space.

3. Which heart chamber receives oxygenated blood from the lungs and pumps it to the rest of the body?

Correct answer: C

Rationale: The correct answer is the left ventricle. It receives oxygenated blood from the left atrium and pumps it to the rest of the body through the aorta. The left atrium receives oxygenated blood from the lungs, the right atrium receives deoxygenated blood from the body, and the right ventricle pumps deoxygenated blood to the lungs.

4. Which type of medication is used to reduce the workload on the heart by slowing down the heart rate and lowering blood pressure?

Correct answer: A

Rationale: The correct answer is A: Beta-blocker. Beta-blockers are medications that reduce the workload on the heart by slowing down the heart rate and lowering blood pressure. They are commonly used in the treatment of heart conditions such as hypertension and heart failure. ACE inhibitors (B) work by dilating blood vessels to reduce blood pressure, calcium channel blockers (C) prevent calcium from entering the heart muscle and blood vessel walls, and diuretics (D) help the body get rid of excess salt and water by increasing urine production.

5. The client is on nitroglycerin patches. What should the nurse include in the client’s education?

Correct answer: A

Rationale: The correct answer is A: 'Rotate the application site with each new patch.' When educating a client using nitroglycerin patches, it is essential to rotate the application site to prevent skin irritation. Choice B is incorrect because applying the patch at the same time each day is not a critical aspect of patch application. Choice C is incorrect as nitroglycerin patches are usually left on for a specific period, typically 12 to 14 hours, before being replaced. Choice D is incorrect because applying the patch to the same site each time can lead to skin irritation and tolerance development.
