1. What diagnostic procedure uses sound waves to create images of the heart and assess its structure and function?

• A. Echocardiogram
• B. MRI
• C. CT scan
• D. X-ray

Correct answer: A

Rationale: An echocardiogram is the correct answer because it is a diagnostic procedure that uses sound waves to create images of the heart, enabling doctors to assess its structure and function. This imaging technique is specifically designed for cardiac assessment. MRI (Choice B), CT scan (Choice C), and X-ray (Choice D) are imaging modalities that are not primarily used for detailed evaluation of the heart's structure and function, making them incorrect choices for this question.

2. What is a surgical procedure to create an opening in the windpipe to assist with breathing?

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

Correct answer: A

Rationale: Tracheostomy is the correct answer. It is a surgical procedure to create an opening in the windpipe (trachea) to assist with breathing. This procedure is commonly used for patients who require long-term ventilation support. Choice B, Lobectomy, involves the removal of a lobe of the lung and is not related to creating an opening in the windpipe. Choice C, Thoracotomy, is a surgical incision into the chest wall and is not specifically related to creating an opening in the windpipe. Choice D, Pleurodesis, is a procedure to treat recurrent pleural effusions by causing the pleural layers to stick together, and it is not related to creating an opening in the windpipe.

3. The client on atorvastatin (Lipitor) should be advised to report which of the following symptoms?

• A. Muscle pain
• B. Headache
• C. Nausea
• D. Dizziness

Correct answer: A

Rationale: The correct answer is A: Muscle pain. Muscle pain can be a sign of rhabdomyolysis, a serious side effect of statins like atorvastatin. Rhabdomyolysis is a condition where muscle fibers break down rapidly and release their contents into the bloodstream, which can lead to kidney damage. Headache, nausea, and dizziness are not commonly associated with atorvastatin use and are less likely to indicate a serious adverse reaction compared to muscle pain.

4. What is the accumulation of fatty deposits along the walls of arteries, leading to reduced blood flow?

• A. Atherosclerosis
• B. Arteriosclerosis
• C. Aneurysm
• D. Thrombosis

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It refers to the buildup of fatty deposits (plaque) along the inner walls of arteries, narrowing the blood vessels and reducing blood flow. This condition can lead to serious complications such as heart attacks or strokes. Arteriosclerosis (choice B) is a broader term that refers to the thickening and hardening of the arterial walls. While related, it is not as specific as atherosclerosis in describing the fatty deposit accumulation. Aneurysm (choice C) is the abnormal bulging of an artery wall that can rupture and cause internal bleeding, not specifically related to fatty deposits. Thrombosis (choice D) is the formation of a blood clot within a blood vessel, which can obstruct blood flow, but it is not directly related to the accumulation of fatty deposits.

5. Which type of medication helps to lower cholesterol levels in the blood?

• A. Statins
• B. Beta-blockers
• C. ACE inhibitors
• D. Diuretics

Correct answer: A

Rationale: Statins are a type of medication specifically designed to lower cholesterol levels in the blood by inhibiting an enzyme involved in cholesterol production. Beta-blockers are mainly used to treat conditions like high blood pressure and heart problems by reducing the heart rate and workload. ACE inhibitors are used to manage conditions like high blood pressure and heart failure by relaxing blood vessels. Diuretics are medications that help the body get rid of excess salt and water by increasing urine production. Therefore, in the context of lowering cholesterol levels, statins are the most appropriate choice.
