Answer and Explanation

The Correct Answer is ["2"]

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.

Correct Answer is ["0.5"]

Explanation

To calculate the dosage of quinapril, the nurse needs to apply the formula: D/H x Q = X, where D is the desired dose, H is the dose on hand, Q is the quantity of the drug, and X is the amount to administer.

In this case, D = 20 mg, H = 40 mg, Q = 1 tablet, and X is unknown.

Plugging in the values, we get: 20/40 x 1 = X.

Simplifying, we get: 0.5 = X.

Therefore, the nurse should administer 0.5 tablets of quinapril.
