Cardiovascular System Test Bank Questions
Question 1 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 2 of 5
The nurse is educating a client who has just been started on Zetia (exetimibe). What does the nurse say to educate the client?
Correct Answer: B
Rationale: The correct answer is B because Zetia interacts with bile acid sequestrants, affecting its absorption. By taking it 2 hours before or 4 hours after a bile acid sequestrant, the absorption of Zetia is maximized. Choice A is incorrect as Zetia can be taken with or without food. Choice C is incorrect as there is no specific interaction with milk. Choice D is incorrect as Zetia can be taken with a statin drug, but the dosing may need to be adjusted based on individual patient factors.
Question 3 of 5
The client is having a standard electrocardiogram. The nurse knows that the QT segment represents what?
Correct Answer: B
Rationale: The correct answer is B because the QT segment on an electrocardiogram represents the total time for ventricular depolarization and repolarization. This segment includes the time from the beginning of ventricular depolarization to the end of ventricular repolarization. Choices A, C, and D are incorrect because the QT segment specifically reflects the electrical activity of the ventricles, not the atria. Additionally, choice D is incorrect as it only refers to ventricular depolarization, not the entire process of ventricular repolarization as well.
Question 4 of 5
The client has a third degree AV block. The definitive treatment for this rhythm is what?
Correct Answer: C
Rationale: The correct answer is C: Pacemaker. In a third degree AV block, there is a complete block in the electrical conduction between the atria and ventricles, leading to a significant decrease in heart rate. The definitive treatment for this condition is the placement of a pacemaker to ensure proper coordination of atrial and ventricular contractions. Adenosine (A) is used for certain types of supraventricular tachycardia, not for AV blocks. Epinephrine (B) is used in cardiac arrest situations to increase heart rate and blood pressure, not for AV blocks. Dopamine (D) is a medication used to increase blood pressure in hypotensive states, not for AV blocks.
Question 5 of 5
Which statement made by a patient with coronary artery disease after the nurse has completed teaching about the therapeutic lifestyle changes (TLC) diet indicates that further teaching is needed?
Correct Answer: D
Rationale: The correct answer is D. Switching to 1% milk (A) and incorporating salmon (B) are both heart-healthy choices. Moderate alcohol consumption like a glass of wine (C) is acceptable in TLC diet. However, peanut butter sandwiches can be high in saturated fat and should be limited in coronary artery disease diet, making choice D incorrect. Further teaching is needed to emphasize the importance of avoiding foods high in saturated fats.
