Cardiovascular Practice Questions Questions
Question 1 of 5
A client with a myocardial infarction and cardiogenic shock is placed on an intra- aortic ballon pump (IAPB). If the device is functioning properly, the balloon inflates when the:
Correct Answer: C
Rationale: Step 1: In cardiogenic shock, the heart is unable to pump effectively, leading to decreased blood flow. Step 2: The IABP helps improve coronary artery perfusion and cardiac output by inflating during diastole. Step 3: During diastole, the aortic valve is closed to prevent blood flow back into the left ventricle. Step 4: The inflated balloon in the aorta increases coronary perfusion and reduces afterload. Summary: Choice C is correct as the balloon inflates when the aortic valve is closed to improve coronary perfusion. Choices A, B, and D are incorrect as they do not align with the physiological mechanism of the IABP.
Question 2 of 5
The nurse is discharging a client to home with a new diagnosis of atrial fibrillation.. The nurse explains that which of the following is the most important symptoms to report to the physician?
Correct Answer: A
Rationale: Step 1: Atrial fibrillation is characterized by an irregular pulse, which can lead to serious complications like stroke. Step 2: Reporting irregular pulse promptly allows the physician to assess the need for interventions to prevent complications. Step 3: Fever (B), fatigue (C), and hemoptysis (D) are not typically associated with atrial fibrillation. Summary: Reporting irregular pulse is crucial for timely management of atrial fibrillation, while fever, fatigue, and hemoptysis are not relevant symptoms in this context.
Question 3 of 5
Which of the following suggestions should the nurse include when conducting health teaching for clients with arterial insufficiency?
Correct Answer: A
Rationale: The correct answer is A because avoiding long periods of sitting and standing helps improve blood circulation in clients with arterial insufficiency. Prolonged sitting or standing can worsen arterial insufficiency by restricting blood flow. Keeping the legs and feet in a raised position (choice B) can help reduce swelling but does not address the root issue of poor circulation. Decreasing ambulation (choice C) would further compromise circulation. Applying moist heat (choice D) can be detrimental as it can dilate blood vessels and exacerbate arterial insufficiency symptoms.
Question 4 of 5
A 75-year-old individual is admitted with a diagnosis of left-sided heart failure and is administered Lasix 80 mg by slow IV push. Which nursing assessment indicates that the Lasix (furosemide) is NOT having the desired effect?
Correct Answer: A
Rationale: The correct answer is A: Oliguria. Oliguria is the decreased urine output, which is an indicator of inadequate response to Lasix in heart failure. Lasix is a diuretic used to reduce fluid overload in heart failure by promoting diuresis. In this case, a decrease in urine output suggests that the medication is not effectively removing excess fluid. For the other choices: B: Decrease in blood pressure - This could be an expected effect of Lasix as it helps reduce fluid volume and can lead to a decrease in blood pressure. C: Absence of crackles - This indicates reduced pulmonary congestion, which is a desired effect of Lasix in heart failure. D: Polydipsia - Increased thirst (polydipsia) is not directly related to the effectiveness of Lasix in treating heart failure. In summary, the presence of oliguria indicates inadequate response to Lasix, while the decrease in blood pressure, absence of crackles, and polydips
Question 5 of 5
Good conduction of electricity from the patient's heart to the monitor requires that the critical care nurse
Correct Answer: C
Rationale: The correct answer is C because placing electrodes with contacts on their anterior and posterior surfaces ensures good conduction of electricity from the heart to the monitor. This placement maximizes the contact area with the skin, leading to better signal transmission. Choice A is incorrect because changing electrode pads periodically may help maintain skin integrity but does not directly impact electrical conduction. Choice B is incorrect as ribs are not good conductors of electricity. Choice D is incorrect as placing electrodes further apart may lead to decreased signal quality and interference.
