A nurse is preparing to administer 0.5 g of cefaclor PO to a client. Available is cefaclor 250 mg capsules. How many capsules should the nurse plan to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Here's the breakdown: Desired dose: 0.5 g (grams) Conversion: 1 gram (g) is equal to 1000 milligrams (mg). Therefore, we need to convert the desired dose from grams to milligrams: Desired dose (mg) = 0.5 g x 1000 mg/g = 500 mg Available dosage: Each capsule contains 250 mg of cefaclor. Calculation of capsules needed: To find the number of capsules needed, we can divide the desired dose (in milligrams) by the amount of medication in each capsule (rounding to the nearest whole number): Number of capsules (rounded) = Desired dose (mg) / Medication per capsule = 500 mg / 250 mg/capsule = 2 capsules (rounded to nearest whole number)
