Correct Answer is ["2"]
Explanation
To calculate the number of capsules needed to administer 0.5 g of cefaclor PO, the nurse should use the following formula:
Number of capsules = (Desired dose / Available dose) x 1 capsule

Number of capsules = (0.5 g / 0.25 g) x 1 capsule
Number of capsules = 2 capsules
Therefore, the nurse should plan to administer 2 capsules of cefaclor PO to the client.
