Cardiovascular System Test Bank Questions
Question 1 of 5
The client has a condition for which a beta agonist has been ordered. What condition might this be?
Correct Answer: D
Rationale: The correct answer is D: Supraventricular tachycardia. Beta agonists, like adenosine or beta-blockers, are commonly used to treat supraventricular tachycardia by slowing down the heart rate. This condition involves rapid heartbeats originating above the ventricles. Choices A, B, and C are incorrect because beta agonists are not typically indicated for shock, hypertension, or cardiac arrhythmias, respectively. In hypertensive emergencies, other antihypertensive medications are preferred. In shock, fluid resuscitation and vasopressors are usually used. For cardiac arrhythmias, antiarrhythmic drugs or cardioversion are more appropriate treatments.
Question 2 of 5
The client is taking an ACE inhibitor. The nurse explains to the client that this drug acts how?
Correct Answer: B
Rationale: The correct answer is B because ACE inhibitors block the conversion of angiotensin I to angiotensin II, leading to vasodilation and decreased blood pressure. Option A is incorrect as calcium channel blockers are a different class of drugs. Option C is incorrect as ACE inhibitors do not have a direct inotropic effect on the heart. Option D is incorrect as ACE inhibitors do not have a direct effect on heart rate.
Question 3 of 5
The client is to take IV heparin. What is a contraindication to giving the drug? Select all that apply.
Correct Answer: B
Rationale: Correct Answer: B (Uncontrolled bleeding) Rationale: 1. Heparin is an anticoagulant that works by preventing blood clots. 2. Uncontrolled bleeding is a contraindication because heparin can increase the risk of bleeding. 3. Deep vein thrombosis (A) is not a contraindication as heparin is used to treat and prevent DVT. 4. Thrombocytosis (C) is an increased platelet count and not a contraindication for heparin. 5. Thrombocytopenia (D) is a low platelet count, which can increase the risk of bleeding, making it a contraindication as well.
Question 4 of 5
The client is being switched from warfarin to Pradaxa. What does the nurse look for as an indication to give the Pradaxa?
Correct Answer: D
Rationale: Rationale: The correct answer is D. Pradaxa, a direct oral anticoagulant, can be given 2 days after stopping warfarin to prevent overlapping anticoagulation effects. This allows for a smooth transition without increasing the risk of bleeding. Choices A, B, and C are incorrect because A) waiting for the INR to normalize may lead to a delay in starting Pradaxa, B) stopping warfarin alone does not indicate the appropriate timing for starting Pradaxa, and C) waiting for the INR to be less than 2 is not specific to initiating Pradaxa.
Question 5 of 5
The client is experiencing a drug-drug interaction with streptokinase and another drug. Which other drug can cause a drug- drug interaction with streptokinase?
Correct Answer: C
Rationale: The correct answer is C: Heparin. Streptokinase is a thrombolytic agent used to dissolve blood clots, while Heparin is an anticoagulant that prevents blood clot formation. When used together, they can increase the risk of bleeding due to their combined anticoagulant effects. Cimetidine (A), Theophylline (B), and Digoxin (D) do not typically interact with streptokinase in the same way as Heparin. This is because they have different mechanisms of action and do not directly affect the clotting process.
