Cardiovascular Practice Questions Questions
Question 1 of 5
Which of the following suggestions should the nurse include when conducting health teaching for clients with arterial insufficiency?
Correct Answer: A
Rationale: Step 1: Arterial insufficiency is caused by decreased blood flow to the extremities. Step 2: Avoiding long periods of sitting and standing helps improve blood circulation. Step 3: Increased mobility prevents blood pooling and promotes better tissue perfusion. Step 4: Keeping legs raised may help temporarily, but prolonged elevation can worsen arterial flow. Step 5: Decreasing ambulation worsens arterial insufficiency by reducing blood flow. Step 6: Applying moist heat can increase vasodilation, worsening the condition. Summary: Choice A is correct as it promotes circulation. Choices B, C, and D are incorrect as they can worsen arterial insufficiency by impeding blood flow or increasing vasodilation.
Question 2 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 better conduction of electricity from the heart to the monitor. This allows for a more accurate reading of the patient's heart activity. Option A is incorrect as changing electrode pads periodically does not necessarily improve conduction. Option B is incorrect as ribs are not excellent conductors of electricity. Option D is incorrect as placing electrodes further apart does not help improve conduction but may instead result in poor signal quality.
Question 3 of 5
Which drug is effective in managing mild to moderate hypotension?
Correct Answer: A
Rationale: The correct answer is A: Phenylephrine. It is a vasoconstrictor that increases blood pressure by constricting blood vessels. This makes it effective in managing mild to moderate hypotension by raising blood pressure. Amiodarone (B) is an antiarrhythmic drug, not used for hypotension. Ibutilide (C) is used for atrial fibrillation/flutter, not hypotension. Milrinone (D) is a phosphodiesterase inhibitor used for heart failure, not hypotension. Therefore, A is the correct choice for managing hypotension.
Question 4 of 5
The nurse is given an order to give the client milrinone (Primacor). For what reason might this drug be ordered?
Correct Answer: A
Rationale: The correct answer is A: For congestive heart failure. Milrinone is a phosphodiesterase inhibitor that helps improve cardiac contractility and output, making it a suitable treatment for congestive heart failure. It is used in patients with reduced ejection fraction and symptoms of heart failure. Choices B, C, and D are incorrect because milrinone is not typically used for hypertension, cardiac arrhythmias, or bradycardia. It is important for the nurse to understand the specific indications for milrinone to ensure safe and effective administration to the client.
Question 5 of 5
Adverse reactions from non-cardio-selective beta blockers include which of the following? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Increases heart rate. Non-cardio-selective beta blockers block beta-1 and beta-2 receptors, leading to unopposed alpha receptor stimulation, causing increased heart rate. Choice A is incorrect as beta blockers typically lower blood pressure. Choice C is incorrect as beta blockers can cause bradycardia, not sinus bradycardia specifically. Choice D is incorrect because non-cardio-selective beta blockers can exacerbate asthma due to beta-2 receptor blockade.
