The nurse is administering an ACE inhibitor to a client. What is the most common side effect?
- A. Cough
- B. Dizziness
- C. Hypotension
- D. Hyperkalemia
Correct Answer: A
Rationale: The correct answer is A: Cough. ACE inhibitors commonly cause a persistent dry cough due to the accumulation of bradykinin. This side effect occurs in up to 20% of patients. Dizziness (B) and hypotension (C) are potential side effects of ACE inhibitors but not as common as cough. Hyperkalemia (D) can occur with ACE inhibitors but is not the most common side effect.

What is a condition where the alveoli are gradually destroyed, leading to shortness of breath and reduced oxygen exchange?
- A. Emphysema
- B. Pulmonary fibrosis
- C. Pulmonary edema
- D. Lung cancer
Correct Answer: A
Rationale: Emphysema is the correct answer. Alveoli destruction in emphysema leads to shortness of breath and reduced oxygen exchange. This condition is primarily caused by smoking and results in irreversible damage to the air sacs in the lungs. Pulmonary fibrosis involves scarring of lung tissue, not alveoli destruction. Pulmonary edema is fluid accumulation in the lungs, disrupting oxygen exchange. Lung cancer is the uncontrolled growth of abnormal cells in the lung, which may not directly lead to alveoli destruction.

- A. Echocardiogram
- B. MRI
- C. CT scan
- D. X-ray
Correct Answer: A
Rationale: The correct answer is A: Echocardiogram. An echocardiogram uses sound waves to create images of the heart, providing detailed information about its structure and function. It is a non-invasive and safe test commonly used to diagnose various heart conditions. MRI (B) uses magnetic fields and radio waves, CT scan (C) uses X-rays, and X-ray (D) uses electromagnetic radiation, but none of these tests specifically utilize sound waves for imaging the heart.
