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.)
The Correct Answer is ["2"]
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
Plugging in the values from the question, we get:
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.

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.
Correct Answer is ["3"]
Explanation
To calculate the number of tablets that the nurse should administer per dose, the nurse needs to convert the prescribed dose of calcium carbonate from grams to milligrams and then divide it by the strength of the available tablets. The formula is:
Prescribed dose (mg) / Tablet strength (mg) = Number of tablets
The prescribed dose of calcium carbonate is 3.9 g PO daily in equally divided doses every 12 hr.
To convert grams to milligrams, multiply by 1000.
Therefore, 3.9 g = 3900 mg.
Since the doses are equally divided every 12 hr, the nurse needs to divide the daily dose by 2 to get the dose per 12 hr. Therefore, 3900 mg / 2 = 1950 mg.
The available tablets have a strength of 650 mg each.
To find the number of tablets per dose, divide the dose per 12 hr by the tablet strength.
Therefore, 1950 mg / 650 mg = 3 tablets.
