The Correct Answer is ["7.5"]
Determine the desired dose.
The nurse needs to administer 75 mg of diphenhydramine.
Calculate the available dose per 2.5 mL.
The available diphenhydramine is 25 mg/2.5 mL.
Calculate the volume to be administered.
Volume = Desired dose (mg) / Concentration (mg/2.5 mL) = 75 mg / (25 mg/2.5 mL) = 75 mg x (2.5 mL/25 mg) = 7.5 mL
