A nurse is preparing to administer rifampin 20 mg/kg/day PO in two divided doses to a client who weighs 132 lb and has tuberculosis. The amount available is rifampin 150 mg capsules. How many capsules should the nurse administer per dose?
(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 ["4"]
To determine how many capsules of rifampin the nurse should administer per dose, we can follow these steps:
Convert the client's weight from pounds to kilograms:
132 lb ÷ 2.2 = 59.9 kg (rounded to one decimal place)
Calculate the total daily dose of rifampin:
20 mg/kg/day × 59.9 kg = 1198 mg/day
Divide the total daily dose into two equal doses for administration:
1198 mg/day ÷ 2 = 599 mg per dose
Calculate the number of capsules needed per dose:
150 mg per capsule
599 mg per dose ÷ 150 mg per capsule = 3.9933...
Rounding to the nearest whole number, the nurse should administer 4 capsules per dose.
Therefore, the nurse should administer 4 capsules of rifampin per dose.

Explanation
To calculate the amount of voriconazole to be administered, we can follow these steps:
Convert the client's weight from pounds to kilograms.
Calculate the total amount of voriconazole needed based on the client's weight.
Determine the volume of the medication to be administered based on the concentration of the available solution.
Let's proceed with the calculations:
Converting the client's weight from pounds to kilograms:
Client's weight = 127 lb
1 lb ≈ 0.453592 kg
Client's weight ≈ 127 lb 0.453592 kg/lb ≈ 57.61 kg
Calculating the total amount of voriconazole needed:
Voriconazole dose = 6 mg/kg 57.61 kg ≈ 345.66 mg
Determining the volume of the medication to be administered:
Available voriconazole concentration = 5 mg/mL
Volume to be administered = 345.66 mg / 5 mg/mL ≈ 69.132 mL
Rounding to the nearest whole number, the nurse should administer 69 mL of voriconazole.

Explanation
To calculate the dose of methylprednisolone sodium succinate that the nurse should administer, we can follow these steps:
Convert the client's weight from pounds to kilograms:
169 lb ÷ 2.2 = 76.82 kg (rounded to two decimal places)
Calculate the dose of methylprednisolone sodium succinate:
30 mg/kg × 76.82 kg = 2,304.6 mg
Determine the volume of methylprednisolone sodium succinate needed using the available concentration:
2,304.6 mg ÷ 125 mg/mL = 18.437 mL
Rounding to the nearest whole number, the nurse should administer 18 mL of methylprednisolone sodium succinate via intermittent IV bolus.
