1. What is the term for a blood clot blocking an artery in the lungs, leading to symptoms like shortness of breath and chest pain?

• A. Pulmonary embolism
• B. Deep vein thrombosis (DVT)
• C. Myocardial infarction
• D. Pneumothorax

Correct answer: A

Rationale: The correct answer is A, pulmonary embolism. A pulmonary embolism occurs when a blood clot travels to the lungs and blocks an artery, causing symptoms like shortness of breath and chest pain. Choice B, deep vein thrombosis (DVT), involves a blood clot forming in a deep vein, usually in the legs. Choice C, myocardial infarction, refers to a heart attack due to blocked blood flow to the heart muscle. Choice D, pneumothorax, is a collapsed lung due to air leaking into the chest cavity.

2. When monitoring a client on dobutamine, what is the most important parameter to assess?

• A. Blood pressure
• B. Heart rate
• C. Oxygen saturation
• D. Respiratory rate

Correct answer: A

Rationale: The correct answer is A: Blood pressure. When a client is on dobutamine, it is crucial to closely monitor their blood pressure as dobutamine can cause significant changes in blood pressure. While heart rate is also important to monitor during this time, blood pressure is the most critical parameter to assess. Oxygen saturation and respiratory rate are also important parameters to monitor in a patient receiving dobutamine, but they are not as crucial as blood pressure in this scenario.

3. The client is on spironolactone (Aldactone). What is the most important dietary instruction?

• A. Avoid foods high in potassium.
• B. Increase intake of foods high in potassium.
• C. Avoid foods high in sodium.
• D. Increase intake of foods high in sodium.

Correct answer: A

Rationale: The correct answer is to avoid foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and can lead to hyperkalemia if too much potassium is consumed. Choices B, C, and D are incorrect because increasing intake of potassium-rich foods can worsen hyperkalemia, while avoiding foods high in sodium is not the primary concern when taking spironolactone.

4. What is a condition where the heart muscle becomes abnormally enlarged, thickened, or stiffened, often leading to heart failure?

• A. Cardiomyopathy
• B. Pericarditis
• C. Aortic stenosis
• D. Mitral valve prolapse

Correct answer: A

Rationale: Cardiomyopathy is the correct answer. It is a condition characterized by the abnormal enlargement, thickening, or stiffening of the heart muscle, which can lead to heart failure. Pericarditis (choice B) is inflammation of the pericardium, the sac surrounding the heart, not directly related to heart muscle enlargement. Aortic stenosis (choice C) is the narrowing of the aortic valve opening, affecting blood flow from the heart, but not directly related to heart muscle enlargement. Mitral valve prolapse (choice D) is a condition where the valve between the left atrium and left ventricle doesn't close properly, causing blood to leak backward, and is not directly related to heart muscle enlargement.

5. 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.
