Cardiovascular System Exam Questions Pdf
1. What is the abnormal accumulation of fluid in the pleural space, often associated with infections or malignancies?
- A. Pleural effusion
- B. Pneumothorax
- C. Pulmonary edema
- D. Atelectasis
Correct answer: A
Rationale: The correct answer is A, pleural effusion. Pleural effusion is the accumulation of excess fluid between the layers of the pleura outside the lungs, often caused by infections, cancer, or other diseases. Pneumothorax (choice B) is the presence of air in the pleural space, not fluid. Pulmonary edema (choice C) is the accumulation of fluid in the lungs' air sacs and tissue, not in the pleural space. Atelectasis (choice D) is the collapse or closure of a lung resulting in reduced or absent gas exchange.
2. What condition is characterized by the inflammation of the heart's outer lining, often causing chest pain and other symptoms?
- A. Pericarditis
- B. Endocarditis
- C. Myocarditis
- D. Valvular heart disease
Correct answer: A
Rationale: Pericarditis is the correct answer because it is the inflammation of the pericardium, the outer lining of the heart. This condition commonly presents with symptoms like chest pain. Endocarditis (choice B) is the inflammation of the inner lining of the heart chambers and valves. Myocarditis (choice C) is the inflammation of the heart muscle itself. Valvular heart disease (choice D) refers to various conditions affecting the heart valves, not specifically the outer lining of the heart.
3. The client on spironolactone should avoid which of the following?
- A. Foods high in potassium
- B. Foods high in sodium
- C. Foods high in calcium
- D. Foods high in chloride
Correct answer: A
Rationale: The correct answer is A: Foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and excrete sodium. Consuming foods high in potassium while on spironolactone can lead to an excess of potassium in the body, potentially causing hyperkalemia. Choices B, C, and D are incorrect because spironolactone does not directly interact with sodium, calcium, or chloride in a way that would require specific dietary restrictions related to these minerals.
4. The nurse is caring for a client on warfarin with an INR of 1.8. What is the most appropriate action?
- A. Increase the dose of warfarin.
- B. Administer vitamin K.
- C. Hold the warfarin and notify the healthcare provider.
- D. Monitor the client’s INR closely.
Correct answer: D
Rationale: An INR of 1.8 is below the therapeutic range for a client on warfarin, indicating the need for monitoring closely to ensure that the INR levels reach the desired therapeutic range. Increasing the dose of warfarin (Choice A) without proper monitoring may lead to an increased risk of bleeding. Administering vitamin K (Choice B) is not typically recommended unless the client is experiencing major bleeding or requires rapid reversal of warfarin's effects. Holding the warfarin and notifying the healthcare provider (Choice C) may be necessary in certain situations, but the immediate action in this case should be to monitor the client's INR closely to guide further management.
5. The client is on warfarin and has an INR of 1.5. What is the nurse’s priority action?
- A. Increase the dose of warfarin.
- B. Hold the next dose of warfarin.
- C. Continue the current dose of warfarin.
- D. Monitor the client’s INR closely.
Correct answer: B
Rationale: An INR of 1.5 is below the therapeutic range for a client on warfarin, indicating that the client may be at risk of clot formation. The nurse's priority action should be to hold the next dose of warfarin to prevent further reduction of the INR. Increasing the dose could potentially lead to an increased risk of bleeding, and continuing the current dose may not be sufficient to bring the INR within the therapeutic range. Monitoring the client's INR closely is important but not the priority action in this scenario.
