1. What is a condition where the heart's electrical impulses are blocked or delayed, leading to a slower or irregular heartbeat?

• A. Heart block
• B. Atrial fibrillation
• C. Tachycardia
• D. Bradycardia

Correct answer: A

Rationale: Heart block is the correct answer. It is a condition where the electrical impulses in the heart are blocked or delayed, resulting in a slower or irregular heartbeat. This can lead to symptoms like dizziness, fainting, or other issues. Atrial fibrillation (B) is characterized by rapid, irregular heartbeats. Tachycardia (C) is a condition where the heart rate is too fast. Bradycardia (D) is the opposite of tachycardia, where the heart rate is too slow.

2. What procedure is used to remove fluid from the pleural space to help a patient breathe more easily?

• A. Thoracentesis
• B. Bronchoscopy
• C. Echocardiogram
• D. CT scan

Correct answer: A

Rationale: Thoracentesis is the correct answer. It is a procedure where a needle is inserted into the pleural space to drain fluid, relieving pressure and helping the patient breathe more easily. Bronchoscopy (choice B) is a procedure used to examine the airways, not to drain fluid. An echocardiogram (choice C) is an imaging test to assess the heart's structure and function, not related to draining pleural fluid. A CT scan (choice D) is a cross-sectional imaging test that provides detailed pictures of the inside of the body, not used for draining pleural fluid.

3. What is the term for inflammation of the bronchial tubes, often leading to a persistent cough and mucus production?

• A. Bronchitis
• B. Asthma
• C. Pneumonia
• D. Cystic fibrosis

Correct answer: A

Rationale: The correct answer is 'Bronchitis.' Bronchitis refers to the inflammation of the bronchial tubes, which can be acute or chronic, leading to symptoms like coughing and increased mucus production. Choice B, 'Asthma,' is a chronic condition characterized by inflammation and narrowing of the airways, often causing wheezing and shortness of breath. Choice C, 'Pneumonia,' is an infection that inflames air sacs in one or both lungs, leading to symptoms like fever, cough, and difficulty breathing. Choice D, 'Cystic fibrosis,' is a genetic disorder that affects the lungs and digestive system, causing mucus buildup and respiratory issues.

4. Which valve opens during ventricular systole and closes during ventricular diastole?

• A. Aortic valve
• B. Pulmonary valve
• C. Mitral valve
• D. Tricuspid valve

Correct answer: B

Rationale: The correct answer is B: Pulmonary valve. The pulmonary valve opens during ventricular systole to allow blood to flow from the right ventricle into the pulmonary artery. The aortic valve opens during ventricular systole to allow blood to flow from the left ventricle into the aorta. The mitral valve and tricuspid valve are atrioventricular valves that open during ventricular diastole to allow blood to flow from the atria into the ventricles.

5. The client on spironolactone (Aldactone) should avoid which type of food?

• A. Foods high in potassium
• B. Foods high in sodium
• C. Foods high in calcium
• D. Foods high in chloride

Correct answer: A

Rationale: The correct answer is A: Foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and excrete sodium. Therefore, clients on spironolactone should avoid foods high in potassium to prevent hyperkalemia, which is an elevated level of potassium in the blood. Choices B, C, and D are incorrect because spironolactone specifically affects potassium levels, not sodium, calcium, or chloride.
