Question

A nurse receives a prescription to administer 0.05 mg/kg of morphine IM to an infant who weighs 9 kg. How will the nurse document the administration of the medication?

0.2 mg administered IM into the ventrogluteal site

0.45 mg administered IM into the vastus lateralis

0.2 mg administered IM into the dorsogluteal site

0.45 mg administered IM into the deltoid muscle

Answer 1

The correct documentation for administering 0.05 mg/kg of morphine to a 9 kg infant is "0.45 mg administered IM into the vastus lateralis." The dosage is calculated by multiplying the dosage per kilogram by the infant's weight.

Step-by-step explanation:

The student asked how a nurse will document the administration of morphine to an infant weighing 9 kg at a dosage of 0.05 mg/kg given IM (intramuscularly). To find the total dose required, multiply the dosage per kilogram by the weight of the infant:

0.05 mg/kg × 9 kg = 0.45 mg

Therefore, the correct documentation would be "0.45 mg administered IM into the vastus lateralis." It is preferred over the ventrogluteal or deltoid for infants due to muscle development.
