1. Which condition involves the heart muscle becoming abnormally thickened, reducing its ability to pump blood?

• A. Hypertrophic cardiomyopathy
• B. Dilated cardiomyopathy
• C. Restrictive cardiomyopathy
• D. Ischemic cardiomyopathy

Correct answer: A

Rationale: The correct answer is A: Hypertrophic cardiomyopathy. In this condition, the heart muscle thickens, leading to a decreased ability to pump blood effectively. Choice B, Dilated cardiomyopathy, is characterized by the heart chambers enlarging and weakening. Choice C, Restrictive cardiomyopathy, involves the heart muscle becoming rigid and less compliant. Choice D, Ischemic cardiomyopathy, is when the heart muscle is weakened due to reduced blood flow.

2. The client on spironolactone (Aldactone) has a potassium level of 5.6 mEq/L. What is the nurse’s priority action?

• A. Hold the spironolactone and notify the healthcare provider.
• B. Administer potassium supplements.
• C. Continue the spironolactone as ordered.
• D. Increase the dose of spironolactone.

Correct answer: A

Rationale: The correct answer is A: Hold the spironolactone and notify the healthcare provider. A potassium level of 5.6 mEq/L is high, indicating hyperkalemia. Spironolactone is a potassium-sparing diuretic that can further elevate potassium levels. Therefore, the priority action is to withhold the medication to prevent exacerbating hyperkalemia and notify the healthcare provider for further management. Option B is incorrect because administering potassium supplements would worsen the hyperkalemia. Option C is incorrect as continuing spironolactone can lead to a further increase in potassium levels. Option D is incorrect as increasing the dose of spironolactone would be inappropriate in the presence of elevated potassium levels.

3. What procedure involves inserting a needle into the pleural space to remove excess fluid and help the patient breathe more easily?

• A. Thoracentesis
• B. Bronchoscopy
• C. Spirometry
• D. Arterial blood gas (ABG)

Correct answer: A

Rationale: Thoracentesis is the correct answer. It is a procedure where a needle is inserted into the pleural space to remove excess fluid, aiding in easier breathing. Bronchoscopy (Choice B) is a procedure to visualize the airways and diagnose lung problems, not specifically for fluid drainage. Spirometry (Choice C) is a test to measure lung function, not a procedure for fluid removal. Arterial blood gas (ABG) (Choice D) is a blood test to assess oxygen and carbon dioxide levels in the blood, not a procedure for draining fluid from the pleural space.

4. What is a surgical procedure to remove one of the lobes of the lungs, often performed to treat lung cancer?

• A. Lobectomy
• B. Pneumonectomy
• C. Thoracotomy
• D. Tracheostomy

Correct answer: A

Rationale: A lobectomy is the correct answer. This surgical procedure involves removing one of the lobes of the lungs, commonly done to treat lung cancer or other serious lung ailments. Choice B, pneumonectomy, involves the complete removal of a lung, not just a lobe. Choice C, thoracotomy, is a surgical incision into the chest wall and is not specific to removing a lung lobe. Choice D, tracheostomy, is the creation of an opening in the windpipe to assist with breathing and is unrelated to lung lobe removal.

5. What condition is characterized by narrowed or blocked arteries in the legs or arms, leading to pain and mobility issues?

• A. Peripheral artery disease
• B. Atherosclerosis
• C. Raynaud's disease
• D. Varicose veins

Correct answer: A

Rationale: The correct answer is A: Peripheral artery disease (PAD). PAD is a condition where the arteries in the legs or arms become narrowed or blocked, leading to pain and mobility issues. Choice B, Atherosclerosis, refers to the buildup of fats, cholesterol, and other substances in and on the artery walls, not specifically the narrowing or blockage in the extremities. Choice C, Raynaud's disease, is characterized by reduced blood flow to the extremities, leading to coldness, numbness, and color changes in the skin, but it is not primarily about narrowed or blocked arteries. Choice D, Varicose veins, involves enlarged, twisted veins usually in the legs, but it is not related to narrowed or blocked arteries causing pain and mobility issues.
