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/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.6"]
To calculate the dosage of diphenhydramine, the nurse needs to use the formula D/H x Q
= X, where D is the desired dose, H is the on-hand dose, Q is the quantity of the on-hand dose, and X is the amount to administer. In this case, D is 30 mg, H is 50 mg/mL, and Q is 1 mL. Plugging these values into the formula, we get:
30/50 x 1 = 0.6
