Cardiovascular Test Bank Questions
Question 1 of 5
The client is taking a class IB anti-arrhythmic drug. What drug might that be?
Correct Answer: B
Rationale: The correct answer is B: Procainamide. Class IB anti-arrhythmic drugs, such as Procainamide, work by blocking sodium channels, leading to a decrease in conduction velocity and an increase in action potential duration. Lidocaine (choice A) is a Class IB drug but is primarily used for acute ventricular arrhythmias. Mexiletine (choice C) is a similar drug to Lidocaine but is not commonly used. Metoprolol (choice D) is a beta-blocker and belongs to a different class of anti-arrhythmic drugs. Hence, Procainamide is the most fitting choice among the options provided.
Question 2 of 5
Priority nursing interventions when a client is on heparin include the following:
Correct Answer: B
Rationale: The correct answer is B: Monitor the IV site for extravasation. This is crucial because heparin is an anticoagulant medication that can cause bleeding if it leaks into the surrounding tissue. By monitoring the IV site for extravasation, nurses can prevent potential complications such as tissue damage or excessive bleeding. Antacids for digestive upset (Choice A) are not directly related to heparin administration. Monitoring signs of acute blood loss (Choice C) is important but not a priority compared to preventing extravasation. Monitoring the respiratory rate (Choice D) is also important but not as directly related to heparin administration as monitoring the IV site for extravasation.
Question 3 of 5
The client is experiencing a drug-drug reaction by taking aspirin with what other drug?
Correct Answer: C
Rationale: The correct answer is C: Heparin. Aspirin and Heparin can interact leading to increased risk of bleeding due to both drugs affecting blood clotting mechanisms. Aspirin inhibits platelet aggregation while Heparin inhibits clotting factors. Choices A, B, and D do not have a significant drug-drug interaction with aspirin in terms of increased bleeding risk.
Question 4 of 5
The client is on a statin medication. The nurse tells the client that the purpose of taking a statin drug is what?
Correct Answer: B
Rationale: The correct answer is B: To reduce total and LDL cholesterol. Statin medications work by blocking an enzyme in the liver that is responsible for producing cholesterol, thereby lowering total and LDL cholesterol levels in the blood. This helps to reduce the risk of cardiovascular events such as heart attacks and strokes. Choice A is incorrect as statins do not directly thin the blood. Choice C is incorrect as statins do not break up existing plaques in the arteries. Choice D is incorrect as statins do not destabilize cholesterol plaques.
Question 5 of 5
The client has a resting heart rate of 80 and a regular rhythm. What is the likely source of electrical activity in this client?
Correct Answer: A
Rationale: The correct answer is A: The sino-atrial node. The SA node is the primary pacemaker of the heart, responsible for initiating the electrical impulses that regulate the heart rate. It is located in the right atrium and typically generates a resting heart rate of around 60-100 beats per minute. In this scenario, with a resting heart rate of 80 and a regular rhythm, the SA node is most likely the source of electrical activity. The other choices (B: AV node, C: Purkinje fibers, D: Bundle of His) are involved in the conduction of electrical impulses within the heart but are not responsible for the initiation of the heartbeat at rest.
