A nurse is preparing to administer digoxin 0.25 mg PO to a client. The amount available is digoxin 0.125 mg tablets. How many tablets should the nurse administer to the client?
(Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
To determine how many tablets of digoxin 0.125 mg are needed to administer a total dose of 0.25 mg, divide the desired dose by the dose per tablet:
0.25 mg (desired dose) ÷ 0.125 mg (dose per tablet) = 2 tablets
Therefore, the nurse should administer 2 tablets of digoxin 0.125 mg to the client to achieve a total dose of 0.25 mg.

Correct Answer is D
Explanation
A. Easy bruising indicates the medication is effective: While some bruising is possible, excessive bruising doesn't necessarily mean the medication is working effectively. It could indicate excessive anticoagulation, requiring dose adjustments.
B. Inject the medication deep into the thigh muscle: Heparin is injected subcutaneously, targeting the fatty tissue layer just beneath the skin. Injecting into the muscle can be painful and decrease absorption.
C. Expect stools to become black and tarry: Black stools can be a sign of upper gastrointestinal bleeding, a potential but uncommon side effect. The nurse should instruct the client to report any black stools but not expect them as a normal occurrence.
D. Use a soft bristle toothbrush: This is important because heparin increases bleeding risk, and a soft-bristled toothbrush minimizes gum irritation and potential bleeding.
