Feedback:
Atropine should be administered to clients who develop bradycardia. Bradycardia may be seen in digitalis toxicity. Milrinone is a miscellaneous inotropic used in heart failure. Furosemide is a loop diuretic that can be used as part of the drug therapy regimen for heart failure. Cholestyramine is used to lower blood cholesterol levels. Milrinone, furosemide, and cholestyramine are not used in the treatment of bradycardia.
