When caring for a patient who has been admitted for his heart failure, the nurse observes that the patient is experiencing bradycardia. Which drug should be administered to patients who develop bradycardia?
Atropine
Cholestyramine
Inamrinone
Milrinone
The Correct Answer is A
A. Atropine is an anticholinergic medication that increases heart rate by blocking vagal effects on the heart, making it the first-line treatment for symptomatic bradycardia.
B. Cholestyramine is a bile acid sequestrant used to lower cholesterol levels and does not have any effects on heart rate.
C. Inamrinone is a phosphodiesterase inhibitor used in heart failure for inotropic support but is not specifically indicated for bradycardia management.
D. Milrinone is also a phosphodiesterase inhibitor used for heart failure but does not address bradycardia directly.

Correct Answer is D
Explanation
A. Sodium levels are important to monitor, but they are not the primary concern with furosemide treatment.
B. Bone marrow function is not a direct concern related to furosemide therapy.
C. Calcium levels are less critical compared to potassium when monitoring a client on furosemide.
D. Potassium levels are correct because furosemide is a loop diuretic that can lead to significant potassium loss, putting the client at risk for hypokalemia, which can have serious cardiac implications.
Correct Answer is A
Explanation
A. An INR of 5.0 indicates a significantly increased risk of bleeding, and administering vitamin K is the appropriate antidote for reversing the effects of warfarin. This is a critical intervention to restore coagulation.
B. Increasing the dose of warfarin is inappropriate in this scenario because the INR is already elevated; it would further increase bleeding risk.
C. While heparin can be used for anticoagulation, it is not appropriate to administer it while the INR is dangerously high without reversing the warfarin first.
D. Continuing warfarin is unsafe at this INR level due to the high risk of bleeding; monitoring for symptoms without intervention is not adequate care.
