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: The correct answer is D: Give the Pradaxa 2 days after stopping the warfarin. This is because Pradaxa does not require INR monitoring like warfarin. By waiting 2 days after stopping warfarin, the risk of overlapping anticoagulant effects is minimized, reducing the risk of bleeding. A: When the INR has normalized - This is incorrect because Pradaxa does not require INR monitoring. B: When the warfarin is stopped, the Pradaxa can be given - This is not ideal as immediate switch may lead to overlapping anticoagulant effects. C: When the INR is less than 2, you can give the Pradaxa - INR level is not a consideration for starting 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 (ezetimibe) should be taken at least 2 hours before or 4 hours after a bile acid sequestrant to avoid interactions that may decrease its absorption. Choice A is incorrect as Zetia can be taken with or without food. Choice C is incorrect as there is no specific restriction on taking Zetia with milk. Choice D is incorrect as Zetia can be taken with a statin drug, but the dosing schedule should be adjusted if taken with a bile acid sequestrant.
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: The total time for ventricular depolarization and repolarization. The QT segment on an electrocardiogram represents the time it takes for both ventricular depolarization (Q wave) and repolarization (T wave) to occur. This segment is important for assessing the risk of arrhythmias, as abnormalities in the QT interval can indicate potential cardiac issues. Choice A is incorrect because the QT segment does not represent atrial depolarization, which is typically seen in the P wave. Choice C is incorrect as it confuses the QT segment with atrial activity. Choice D is incorrect as it only mentions ventricular depolarization, while the QT segment encompasses both depolarization and repolarization of the ventricles.
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. A third-degree AV block is a complete block of electrical signals between the atria and ventricles, leading to a slow heart rate and potential hemodynamic instability. The definitive treatment is to implant a pacemaker to regulate the heart rate and ensure proper conduction. Adenosine (A) is used for supraventricular tachycardias, not AV blocks. Epinephrine (B) and dopamine (D) are used for treating bradycardia in emergency situations but are not definitive treatments for third-degree AV block.
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 because peanut butter is a good source of healthy fats and protein, which can be included in a TLC diet in moderation. Switching to 1% milk (A) reduces saturated fat intake, eating salmon (B) provides omega-3 fatty acids, and having a glass of wine (C) in moderation may have cardiovascular benefits. Peanut butter can be part of a heart-healthy diet, so the patient does not need to eliminate it completely.
