The nurse is withdrawing medication from a new multiuse vial. After use, which action does the nurse perform? Select all that apply.
Discard the vial since it should not be used again.
Label the vial with the date first used.
Label the vial with the facility's phone number.
Label the vial with the time opened.
Label the vial with the nurse's initials.
Correct Answer : B,D,E
A. Discard the vial since it should not be used again: A multiuse vial is specifically designed to be used multiple times, often for up to 28 days after opening (depending on the medication and facility policy), provided aseptic technique is maintained.
B. Label the vial with the date first used: Labeling the vial with the date it was opened is crucial for ensuring the medication is not used past its expiration date (usually 28 days after opening).
C. Label the vial with the facility's phone number: The facility's phone number is irrelevant to the safe use and tracking of the medication vial.
D. Label the vial with the time opened: While the date is essential, the time opened is also critical for establishing the exact 28-day (or other specified period) expiration time for the opened vial.
E. Label the vial with the nurse's initials: Adding the initials of the nurse who opened it provides accountability and a point of contact for any questions regarding the vial's history.

Correct Answer is A
Explanation
A. 3.5 mL:The directions explicitly state: "For IM use, add 3.5mL sterile water for injection". This is the volume of diluent added to reconstitute the powder.
B. 250 mg/mL:This is the resulting concentration after the diluent has been added, not the volume of the diluent itself.
C. 1mL:This volume is too small and is an incorrect interpretation of the label. 1Ml is the volume that contains 250mg of the drug, but it is not the volume of diluent added.
D. 35 mL:This is 10 times the correct amount and is an incorrect reading of the label. Adding this much would severely dilute the medication.
Correct Answer is A
Explanation
Dimensional analysis:
- Ordered dose: 8 mg IM.
- Available concentration: 5 mg per 1 mL.
- Volume needed = 8 mg × (1 mL / 5 mg) = 1.6 mL.
A. 3 mL:A 3 mL syringe is appropriate for IM injections and can accurately deliver 1.6 mL. It provides clear mL markings and enough capacity for the dose.
B. Insulin U-100:Insulin syringes are calibrated in insulin units, not mL, and are designed for subcutaneous insulin, not IM lorazepam.
C. Insulin U-50:Same issue as U-100; calibrated in units and not appropriate for IM medication administration.
D. 1 mL:A 1 mL syringe cannot hold the required 1.6 mL volume, so it is insufficient for this dose.
