Cardiovascular System Exam
1. What is a condition where the walls of the arteries in the lungs become thickened and stiff, leading to increased blood pressure in the pulmonary arteries?
- A. Pulmonary hypertension
- B. Pulmonary fibrosis
- C. Pulmonary embolism
- D. Pulmonary edema
Correct answer: A
Rationale: Pulmonary hypertension is a condition characterized by the thickening and stiffening of the arteries in the lungs, resulting in elevated blood pressure in the pulmonary arteries. This condition is distinct from the other choices provided. Pulmonary fibrosis involves scarring of lung tissue, pulmonary embolism is a blockage in the pulmonary artery, and pulmonary edema is the accumulation of fluid in the lungs.
2. Which dietary supplement is often recommended for patients taking statins to lower cholesterol?
- A. Iron
- B. Coenzyme Q10
- C. Calcium
- D. Magnesium
Correct answer: B
Rationale: Coenzyme Q10 is often recommended for patients on statins because it may help reduce muscle pain, a common side effect of these medications. Iron (Choice A) is not typically recommended for patients taking statins to lower cholesterol. Calcium (Choice C) and Magnesium (Choice D) are not specifically indicated for addressing muscle pain associated with statin use, making them less suitable choices in this scenario.
3. Which of the following lab tests should NOT be used for diagnosing connective tissue diseases?
- A. Rheumatoid factor (RF)
- B. Erythrocyte sedimentation rate (ESR)
- C. Anti-nuclear antibody (ANA)
- D. Thyroid stimulating hormone (TSH)
Correct answer: Thyroid stimulating hormone (TSH)
Rationale:
4. A nurse is reinforcing dietary teaching with a client who has vitamin A deficiency. Which of the following food choices should the nurse recommend the best source of vitamin A?
- A. 1 small baked sweet potato
- B. 1 cup avocado
- C. 1 cup green beans
- D. 1 large apple
Correct answer: A
Rationale: Sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, essential for vision and immune function.
5. In the management of heart failure, which diuretic is preferred due to its demonstrated significant mortality reduction in patients with heart failure?
- A. Furosemide (Lasix)
- B. Hydrochlorothiazide (HydroDIURIL)
- C. Spironolactone (Aldactone)
- D. Mannitol (Osmitrol)
Correct answer: C
Rationale: Spironolactone, a potassium-sparing diuretic, is the preferred choice in heart failure due to its cardio-protective effect, leading to reduced mortality in patients with heart failure. It is used to manage both hypertension and edema, making it a valuable option in heart failure treatment.
