Calculation
A nurse is preparing to administer diphenhydramine 35 mg IM to a client who has schizophrenia. Available is diphenhydramine for injection 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.)
mL
Explanation & Rationale
To determine how many mL to administer, use the formula: mL= Desired Dose/Available Dose per mL mL= 35mg/50 mg/mL = 0.7 mL Thus, the nurse should administer 0.7 mL of diphenhydramine.
