A nurse is preparing to administer morphine 0.2 mg/kg IM to a client who weighs 99 lb. The Available is morphine injection 10 mg/ml. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use leading zero if it applies. Do not use a trailing zero.)

Convert the client's weight from pounds to kilograms: There are 2.205 pounds in 1 kilogram. 99 lb = 99 lb / 2.205 lb/kg = 44.91 kg (rounded to two decimal places). Determine the total dosage: The client is prescribed 0.2 mg/kg of morphine. The client weighs 44.91 kg. The total dosage is 0.2 mg/kg x 44.91 kg = 8.982 mg. Determine the volume per dose: The morphine injection contains 10 mg per 1 mL. The nurse needs to administer 8.982 mg per dose. To find the volume per dose: 10 mg / 1 mL = 8.982 mg / x mL Cross-multiplying gives us: 10x = 8.982 Dividing both sides by 10, we get: x = 0.8982 mL Round the answer to the nearest tenth: Rounding 0.8982 to the nearest tenth gives us 0.9 mL.
