The nurse reads the following drug label:
Cyanocobalamin
Injection, USP
1,000 mcg per mL
For IM or SUBQ Use Only
1 mL Multi-Dose Vial
Contains a preservative.
Protect from light.
The nurse demonstrates safe practice when the routes of administration are identified as:
IV, SL
IM, SUBQ
IV, IM
IM, PO
The Correct Answer is B
A. IV, SL: Intravenous (IV) and sublingual (SL) routes are not indicated on the label. Administering via these routes could result in improper absorption or adverse effects.
B. IM, SUBQ: The label clearly states “For IM or SUBQ Use Only,” indicating that intramuscular and subcutaneous administration are the safe and approved routes for cyanocobalamin. This ensures correct absorption and patient safety.
C. IV, IM: While intramuscular (IM) is correct, intravenous (IV) is not listed as an approved route. Using IV could cause complications or medication errors.
D. IM, PO: Oral (PO) administration is not appropriate for cyanocobalamin in this formulation. The medication is designed for injection, and taking it orally would prevent effective absorption.
