1. What condition is characterized by the inflammation of the pleura, causing sharp chest pain that worsens with breathing?

• A. Pleurisy
• B. Pericarditis
• C. Endocarditis
• D. Myocarditis

Correct answer: A

Rationale: The correct answer is Pleurisy. Pleurisy is the inflammation of the pleura, the lining surrounding the lungs, which causes sharp chest pain that worsens with breathing. Pericarditis (choice B) is the inflammation of the pericardium, the sac around the heart, which typically causes chest pain that worsens when lying down. Endocarditis (choice C) is the inflammation of the inner lining of the heart chambers and valves, leading to symptoms like fever, fatigue, and abnormal heart sounds. Myocarditis (choice D) is inflammation of the heart muscle, which can cause symptoms such as chest pain, fatigue, and shortness of breath.

2. What is a condition where the arteries that supply blood to the heart muscle become hardened and narrowed due to the buildup of plaque?

• A. Atherosclerosis
• B. Aneurysm
• C. Arrhythmia
• D. Peripheral artery disease

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It is a condition characterized by the hardening and narrowing of arteries supplying blood to the heart due to plaque buildup. This condition increases the risk of heart attacks. Choice B, aneurysm, refers to a balloon-like bulge in an artery, not the hardening and narrowing of arteries. Choice C, arrhythmia, is an irregular heartbeat and not related to arterial hardening. Choice D, peripheral artery disease, involves the narrowing of arteries that supply blood to the limbs, not specifically to the heart.

3. Which heart chamber receives oxygenated blood from the four pulmonary veins and serves as a reservoir during ventricular systole?

• A. Right atrium
• B. Left atrium
• C. Right ventricle
• D. Left ventricle

Correct answer: B

Rationale: The correct answer is B, Left atrium. The left atrium receives oxygenated blood from the lungs via the four pulmonary veins and acts as a holding chamber before the blood is pumped into the left ventricle. Choice A, Right atrium, is incorrect as it receives deoxygenated blood from the body via the vena cava. Choices C and D, Right ventricle and Left ventricle, are incorrect as they receive blood from the atria, not the pulmonary veins.

4. Which condition is characterized by fluid collection in the lungs, making it difficult to breathe?

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

Correct answer: A

Rationale: The correct answer is A, Pulmonary edema. Pulmonary edema is a condition where fluid accumulates in the air sacs of the lungs, causing breathing difficulty. Pleurisy (choice B) is inflammation of the pleura causing chest pain. Pleural effusion (choice C) is the buildup of excess fluid in the pleural space, the area between the layers of tissue that line the lungs and chest cavity. Pneumothorax (choice D) is the presence of air in the pleural space, which can cause a lung to collapse.

5. The client on furosemide is at risk for which electrolyte imbalance?

• A. Hypokalemia
• B. Hypernatremia
• C. Hyperkalemia
• D. Hyponatremia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance is a significant risk associated with the use of diuretics. Choice B, Hypernatremia, is incorrect as furosemide is not known to cause high sodium levels. Choice C, Hyperkalemia, is also incorrect as furosemide tends to cause potassium depletion rather than excess. Choice D, Hyponatremia, is not directly related to furosemide use.
