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

Correct Answer is ["25"]
Explanation
To answer this question, you need to use the formula:
gtt/min = (Volume x Drop factor) / Time
Plug in the given values:
gtt/min = (100 mL x 15 gtt/mL) / 60 min
Simplify and solve:
gtt/min = 1500 gtt / 60 min gtt/min = 25 gtt/min
Therefore, the nurse should set the manual IV infusion to deliver 25 gtt/min.
