ATI Cardiovascular Test Bank Questions
Question 1 of 5
The client has stable angina. What class of drug is used to treat angina? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Organic nitrates. Organic nitrates are vasodilators that help relax and widen blood vessels, reducing the workload on the heart and improving blood flow to the heart muscle, thus relieving angina symptoms. Digoxin (A) is used for heart failure and arrhythmias, not angina. Adenosine (C) is used for supraventricular tachycardia, not angina. Beta blockers (D) are also used to treat angina by reducing heart rate and blood pressure, but organic nitrates are the first-line treatment for stable angina.
Question 2 of 5
Priority nursing interventions when a client is being given warfarin include what?
Correct Answer: D
Rationale: The correct answer is D: Monitor the INR. The International Normalized Ratio (INR) is crucial in monitoring the effectiveness of warfarin therapy. Maintaining the INR within the therapeutic range is essential to prevent clotting or bleeding. Monitoring blood pressure (A) is important but not specific to warfarin therapy. Monitoring vitamin K levels (B) is unnecessary as warfarin works by inhibiting vitamin K-dependent clotting factors. Monitoring warfarin levels (C) is not typically done as INR is a more accurate reflection of its effects. Therefore, monitoring the INR is the priority intervention for clients on warfarin therapy.
Question 3 of 5
The client is taking a medication that digests the fibrin network in a blood clot. What medication is the client likely taking?
Correct Answer: B
Rationale: The correct answer is B: Streptokinase. Streptokinase is a thrombolytic medication that works by breaking down the fibrin network in a blood clot, helping to dissolve the clot. This action is essential in treating conditions like heart attacks and strokes where blood clots obstruct blood flow. Rationale: A: Heparin works by inhibiting the formation of new clots but does not directly digest the fibrin network in an existing clot. C: Warfarin is an anticoagulant that interferes with the clotting process by affecting vitamin K-dependent clotting factors, but it does not directly digest fibrin. D: Ticlid is an antiplatelet medication that prevents platelets from clumping together to form clots, but it does not digest the fibrin network in a clot.
Question 4 of 5
The client is taking gemfibrozil. What contraindication to taking the drug should the nurse tell the client about?
Correct Answer: C
Rationale: The correct answer is C: Active gallbladder disease. Gemfibrozil can increase the risk of gallstones and exacerbate gallbladder disease. The nurse should inform the client about this contraindication to avoid potential complications. A: History of MI is not a contraindication to taking gemfibrozil. In fact, gemfibrozil may be prescribed to reduce the risk of cardiovascular events in patients with a history of MI. B: History of elevated triglyceride levels is actually an indication for using gemfibrozil, not a contraindication. D: Taking aspirin with gemfibrozil can increase the risk of bleeding but is not a specific contraindication.
Question 5 of 5
The client has a diastolic murmur. This means that the murmur is heard when in the cardiac cycle?
Correct Answer: D
Rationale: The correct answer is D (Between the S2 and the S1 beat) because a diastolic murmur occurs during the filling phase of the cardiac cycle, which is between the closure of the semilunar valves (S2) and the closure of the atrioventricular valves (S1). This murmur indicates abnormalities in the heart valves during ventricular relaxation. Choices A and C are incorrect because S1 and S2 beats correspond to systole, not diastole. Choice B is incorrect as it would indicate a continuous murmur throughout the cardiac cycle, which is not characteristic of a diastolic murmur.
