Correct Answer is ["0.7"]

Explanation

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 ["2"]

Explanation

To calculate the number of tablets needed to administer promethazine 25 mg PO, the nurse should use the following formula:

(number of tablets) = (desired dose) / (available dose)

Substituting the values given in the question, we get:

(number of tablets) = (25 mg) / (12.5 mg)

Simplifying, we get:

(number of tablets) = 2

Therefore, the nurse should administer 2 tablets of promethazine 12.5 mg to the client.
