Cardiovascular System Exam Questions
1. What is a condition where the heart beats too fast, reducing its ability to pump blood effectively?
- A. Tachycardia
- B. Bradycardia
- C. Arrhythmia
- D. Ventricular fibrillation
Correct answer: A
Rationale: Tachycardia is the correct answer because it is a condition characterized by a fast heart rate, which can decrease the heart's efficiency in pumping blood. Bradycardia, on the other hand, refers to a slow heart rate, which is the opposite of what is described in the question. Arrhythmia is a general term for any irregularity in the heart's rhythm, not necessarily specifically related to a fast heart rate. Ventricular fibrillation is a life-threatening arrhythmia where the heart's lower chambers quiver instead of pumping blood effectively, but it is not specifically characterized by a fast heart rate.
2. Can soluble fibers be fermented by gut bacteria?
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: A
Rationale: Soluble fibers can indeed be fermented by gut bacteria in the large intestine, leading to the production of beneficial short-chain fatty acids. This fermentation process is important for gut health and provides various health benefits. Therefore, the statement is true. Choice B is incorrect as it contradicts the known scientific fact that soluble fibers can be broken down by gut bacteria through fermentation.
3. The client complains of fatigue and joint pain and reports that they are unable to walk due to pain in the knees. What is the most appropriate statement by the nurse?
- A. “You just have arthritis and should take some ibuprofen.”
- B. “You should avoid walking. This might be osteoporosis.”
- C. “Please tell me more about when your pain started.”
- D. “You need to lose weight or the pain won’t go away.”
Correct answer: “Please tell me more about when your pain started.”
Rationale:
4. Which drugs contribute to peptic ulcers?
- A. Antacids
- B. Certain antibiotics
- C. Cholesterol-lowering medications
- D. Nonsteroidal anti-inflammatory drugs
Correct answer: D
Rationale: Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to contribute to the development of peptic ulcers by affecting the protective lining of the stomach and increasing stomach acid production. This can lead to irritation and ulcer formation. Antacids are actually used to relieve symptoms of peptic ulcers by neutralizing stomach acid. Certain antibiotics may be prescribed to treat H. pylori infection, a common cause of peptic ulcers. Cholesterol-lowering medications are not typically associated with causing peptic ulcers.
5. A nurse is reviewing the laboratory results for a client who has Cushing's disease. The nurse should expect the client to have an increase in which of the following laboratory values?
- A. Serum glucose level.
- B. Serum calcium level.
- C. Lymphocyte count.
- D. Serum potassium level.
Correct answer: A
Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, elevated cortisol levels lead to increased gluconeogenesis, insulin resistance, and breakdown of proteins and fats, resulting in elevated blood glucose levels. This is known as hyperglycemia. The other options, including serum calcium level (choice B), lymphocyte count (choice C), and serum potassium level (choice D), are not typically affected by Cushing's disease. Therefore, they are incorrect choices.
