Question 1 of 23 :
A nurse is preparing to administer diphenhydramine 30 mg IM stat to a client who is having an allergic reaction. Available is diphenhydramine 50 mg/1 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: 0.6
Desired dose = 30 mg.
Available concentration = 50 mg/1 mL.
- Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 30 mg / 50 mg/mL
= 0.6 mL.
