Cardiovascular Practice Questions Questions
Question 1 of 5
The client has been found to have a normal cardiac output. What value represents a normal cardiac output?
Correct Answer: C
Rationale: The correct answer is C (4 l/min) because a normal cardiac output typically ranges from 4 to 8 liters per minute in adults. This value ensures adequate blood circulation to meet the body's needs. Choices A, B, and D are incorrect as they fall outside the normal range and may indicate either insufficient or excessive cardiac output, which can lead to health issues.
Question 2 of 5
When developing a teaching plan for a 61-yr-old patient with multiple risk factors for coronary artery disease (CAD), the nurse should focus primarily on the
Correct Answer: B
Rationale: The correct answer is B: elevated low-density lipoprotein (LDL) level. Elevated LDL is a major risk factor for CAD, especially in older adults. Focusing on lowering LDL levels through lifestyle modifications or medications can help reduce the risk of CAD. Family history (A) is important but not modifiable. Gender (C) is a risk factor, but LDL level is more directly related to CAD risk. Aging (D) increases risk, but addressing specific risk factors like LDL level is crucial in prevention.
Question 3 of 5
Heparin is ordered for a patient with a non–ST-segment-elevation myocardial infarction (NSTEMI). What is the purpose of the heparin?
Correct Answer: C
Rationale: The correct answer is C: Heparin prevents the development of new clots in the coronary arteries. Heparin is an anticoagulant that works by inhibiting the formation of blood clots. In the case of NSTEMI, there is a risk of clot formation in the coronary arteries, which can worsen the condition. By preventing the development of new clots, heparin helps maintain blood flow to the heart muscle. Choice A is incorrect because heparin actually inhibits platelet aggregation, preventing clot formation. Choice B is incorrect as heparin does not directly affect the size of the plaque in the arteries. Choice D is incorrect because heparin does not actively dissolve existing blood clots, but rather prevents new clots from forming.
Question 4 of 5
A patient who is recovering from an acute myocardial infarction (AMI) asks the nurse when sexual intercourse can be resumed. Which response by the nurse is best?
Correct Answer: B
Rationale: The correct answer is B because it provides accurate information about the energy expenditure during sexual activity, which can be a concern for patients recovering from an AMI. Climbing two flights of stairs is a useful reference point for patients to gauge their readiness for physical exertion. Choice A is incorrect as it oversimplifies the potential risks and complications associated with resuming sexual activity post-AMI. Choice C is incorrect as it suggests that the doctor will provide specific guidelines without addressing the patient's concerns in the moment. Choice D is incorrect as it focuses solely on emotional intimacy rather than addressing the patient's question about physical activity.
Question 5 of 5
Which information about a patient who has been receiving thrombolytic therapy for an acute myocardial infarction is most important for the nurse to communicate to the health care provider?
Correct Answer: C
Rationale: The correct answer is C: No change in the patient's reported level of chest pain. This is the most important information to communicate because it indicates a lack of improvement in the patient's condition despite thrombolytic therapy. This suggests a potential complication or treatment failure that needs immediate attention. A: An increase in troponin levels from baseline may indicate ongoing myocardial damage but may not be as urgent as persistent chest pain. B: A large bruise at the IV site is a common side effect of thrombolytic therapy and can usually be managed without immediate intervention. D: A decrease in ST-segment elevation on the ECG is a positive sign of reperfusion but may not be as urgent as persistent chest pain.
