ATI Cardiovascular Test Bank Questions
Question 1 of 5
The client is given an alpha agonist. What might it be used for?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 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 3 of 5
The client is on IV heparin. You explain that this drug does what?
Correct Answer: C
Rationale: The correct answer is C because heparin works by inactivating clotting factors, specifically by enhancing the activity of antithrombin III which inhibits factors IIa (thrombin) and Xa. This prevents the formation of blood clots. Option A is incorrect because heparin does not act as an antiplatelet drug. Option B is incorrect because heparin does not decrease the synthesis of clotting factors. Option D is incorrect because heparin does not directly promote the lysis of fibrin.
Question 4 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 5 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.
