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 dose of darbepoetin that the nurse should administer, we can follow these steps:
Convert the client's weight from pounds to kilograms:
198 lb ÷ 2.2 = 89.82 kg (rounded to two decimal places)
Calculate the dose of darbepoetin:
0.45 mcg/kg × 89.82 kg = 40.41 mcg
Determine the volume of darbepoetin needed using the available concentration:
40.41 mcg ÷ 300 mcg/mL = 0.1347 mL
Rounding to the nearest tenth, the nurse should administer 0.1 mL of darbepoetin subcutaneously once weekly.
Correct Answer is ["25"]
Explanation
To calculate the IV flow rate in drops per minute (gtt/min) for the administration of clindamycin, we can follow these steps:
First, we need to determine the total number of minutes for the infusion, which is given as 1 hour:
1 hour × 60 minutes/hour = 60 minutes
Next, we calculate the total number of drops needed for the infusion:
The total volume to be infused is 100 mL.
The drop factor is 15 gtt/mL.
100 mL × 15 gtt/mL = 1500 gtt
Calculate the IV flow rate in drops per minute:
1500 gtt ÷ 60 min = 25 gtt/min
Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 25 gtt/min.
