A nurse is preparing to administer morphine 8mg IM to a client who is postpartum. Available is morphine injection 10 mg/mL. How many mL should the nurse plan to administer? (Round the answer to the nearest tenth. Use leading zero if it applies.)
The Correct Answer is ["0.8"]
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
8 mg / Volume = 10 mg/mL
Step 3: Solve for the unknown volume:
Volume = 8 mg / 10 mg/mL
Step 4: Calculate the volume:
Volume = 0.8 mL
