A nurse is preparing to administer morphine 0.2 mg/kg IM to a client who weighs 99 lb. Available is morphine injection 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.9
Identify the given information:
Dose of morphine: 0.2 mg/kg
Weight of the client: 99 lb
Concentration of morphine injection: 10 mg/mL
Convert the client's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total dose of morphine in mg:
Total dose = Dose/kg x Weight (kg)
Substitute the values:
Total dose = 0.2 mg/kg x 99 lb x (0.453592 kg/1 lb)
Total dose ≈ 8.99 mg
Calculate the volume of morphine injection to be administered:
Volume = Total dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 8.99 mg / 10 mg/mL
Volume ≈ 0.899 mL
Round the answer to the nearest tenth:
Volume ≈ 0.9 mL
