Correct Answer is ["0.5"]

Explanation

To answer this question, we need to use 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 on hand, and X is the amount to administer. In this case, D is 15 mg, H is 30 mg, Q is 1 mL, and X is unknown. Plugging these values into the formula, we get:

15/30 x 1 = X

0.5 = X

Therefore, the nurse will administer 0.5 mL of codeine to the patient every four hours.
