A nurse is preparing to administer diphenhydramine 35 mg IM. Available is diphenhydramine 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.)
The Correct Answer is ["0.7"]
To calculate the dosage of diphenhydramine injection, the nurse should use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 35 mg, H is 50 mg/mL, and Q is 1 mL.
Plugging these values into the formula, we get:
35 mg / 50 mg/mL x 1 mL = 0.7 mL
Therefore, the nurse should administer 0.7 mL of diphenhydramine injection.

Correct Answer is ["0.7"]
Explanation
To calculate the dosage of morphine for a child, the nurse needs to convert the child's weight from pounds to kilograms and then multiply it by the prescribed dose per kilogram. The nurse also needs to divide the resulting amount by the concentration of the morphine injection to get the volume to be administered. The formula is:
Volume (mL) = (Weight (kg) x Dose (mg/kg)) / Concentration (mg/mL)
In this case, the child weighs 77 lb, which is equivalent to 35 kg (77 / 2.2 = 35). The prescribed dose is 0.2 mg/kg and the concentration of the morphine injection is 10 mg/mL. Therefore, the volume to be administered is:
Volume (mL) = (35 x 0.2) / 10
Volume (mL) = 0.7
The nurse should round the answer to the nearest tenth, which is 0.7 mL.
