A client receives a prescription for warfarin 2 mg IM daily. The pharmacy delivers a vial labeled, warfarin 5 mg/single-use vial. The instructions read, reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL. How many mL should the nurse administer? (Enter the numerical value only.)
The Correct Answer is ["2 mg"]
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Substituting the values, the nurse gets:
Volume (mL) = 2 mg / 2 mg/mL
Volume (mL) = 1 mL
Therefore, the nurse should administer 1 mL of the reconstituted solution to deliver 2 mg of warfarin to the client.

- Calculate the time of infusion in minutes: 7 hours x 60 minutes = 420 minutes
- Calculate the infusion rate in mL/minute: 630 mL / 420 minutes = 1.5 mL/minute
- Calculate the infusion rate in drops/minute: 1.5 mL/minute x 10 gtt/mL = 15 gtt/minute
- The nurse should regulate the infusion to deliver 15 drops/minute
