Question 12 :
A nurse is preparing to administer promethazine 25 mg IM to a client. Available is promethazine 50 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: ["0.5ml"]
To calculate the volume (mL) that the nurse should administer, you can use the following formula:
Volume (mL) = Dose (mg)/Concentration (mg/mL)
In this case:
Volume =25 mg/50 mg/mL
Volume=0.5mL
Therefore, the nurse should administer 0.5 mL of promethazine for the 25 mg IM dose, rounded to the nearest tenth.
