A nurse is caring for a client who has been taking warfarin and has an international normalized ratio (INR) time of 5. Which of the following medications should the nurse anticipate the provider to prescribe?
Ferrous sulfate
Heparin
Prednisone
Vitamin K
The Correct Answer is D
A. Ferrous sulfate: Ferrous sulfate is an iron supplement used to treat or prevent low blood levels of iron (such as those caused by anemia or pregnancy). It is not used to treat high INR levels.
B. Heparin: Heparin is an anticoagulant, or blood thinner, that prevents the formation of blood clots. It would not be used to treat a high INR level, as it could potentially increase the INR even further.
C. Prednisone: Prednisone is a corticosteroid that reduces inflammation in the body. It is not used to treat high INR levels.
D. Vitamin K: This is correct. Vitamin K is used to help blood clot and is given to patients who have a high INR level to reduce the risk of bleeding. Warfarin works by blocking the effects of vitamin K, so giving vitamin K can help reverse the effects of warfarin and lower the INR.

Correct Answer is B
Explanation
A. Diltiazem: Diltiazem is a calcium channel blocker used to treat high blood pressure and heart rhythm disorders. However, it can further lower the heart rate, which is not desirable in this case as the client’s heart rate is already low.
B. Atropine: This is correct. Atropine is often used to treat bradycardia (low heart rate). It works by blocking the action of the vagus nerve on the heart, which increases the heart rate.
C. Digoxin: Digoxin is used to treat heart failure and atrial fibrillation1. However, one of its side effects is that it can lower the heart rate, so it would not be appropriate to give to a client who already has a low heart rate.
D. Carvedilol: Carvedilol is a beta-blocker used to treat high blood pressure and heart failure1. Like other beta-blockers, it can lower the heart rate, so it would not be appropriate to give to a client who already has a low heart rate.
