1. 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.

2. A client on a beta blocker has a blood pressure of 90/60 mm Hg. What is the nurse’s priority action?

• A. Hold the beta blocker and notify the healthcare provider.
• B. Administer the beta blocker as ordered.
• C. Administer a diuretic to reduce blood pressure.
• D. Continue to monitor the client and reassess in 30 minutes.

Correct answer: A

Rationale: The correct answer is to hold the beta blocker and notify the healthcare provider. A blood pressure of 90/60 mm Hg is already low, and beta blockers can further decrease blood pressure. Administering the beta blocker can potentially worsen the situation, leading to complications. Administering a diuretic or continuing to monitor the client without taking immediate action could delay necessary intervention. Therefore, holding the beta blocker and involving the healthcare provider promptly is crucial in this scenario.

3. This is the inflammation of the heart's inner lining, usually caused by an infection.

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

Correct answer: A

Rationale: Endocarditis is the inflammation of the inner lining of the heart's chambers and valves, usually caused by a bacterial infection. Myocarditis is the inflammation of the heart muscle, Pericarditis is the inflammation of the pericardium (the outer lining of the heart), and Valvulitis is the inflammation of the heart valves. Therefore, in this case, the correct answer is Endocarditis as it specifically refers to the inflammation of the heart's inner lining.

4. Which term refers to the contraction phase of the heart when blood is ejected from the chambers?

• A. Systole
• B. Diastole
• C. Contractility
• D. Afterload

Correct answer: A

Rationale: The correct answer is A, systole. Systole is the phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. During diastole (choice B), the heart relaxes and fills with blood, contrasting with systole. Contractility (choice C) refers to the ability of the heart to contract effectively. Afterload (choice D) is the pressure the heart must work against to eject blood during systole.

5. What is a condition where the heart's ability to pump blood is reduced because the heart muscle is enlarged, thickened, or stiffened?

• A. Cardiomyopathy
• B. Endocarditis
• C. Myocarditis
• D. Aortic stenosis

Correct answer: A

Rationale: Cardiomyopathy is the correct answer. It is a condition characterized by the enlargement, thickening, or stiffening of the heart muscle, leading to a reduced ability of the heart to pump blood effectively. Endocarditis (Choice B) is the inflammation of the inner lining of the heart chambers and valves, not specifically related to the heart muscle. Myocarditis (Choice C) is inflammation of the heart muscle typically caused by a viral infection, not directly related to the heart muscle's structure. Aortic stenosis (Choice D) is a condition characterized by the narrowing of the aortic valve opening, affecting blood flow from the heart's left ventricle to the aorta, different from the structural changes seen in cardiomyopathy.
