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.

Correct Answer is ["83"]
Explanation
To calculate the IV flow rate in drops per minute, we can use the following formula:
IV flow rate (gtt/min) = (Volume to be infused in mL drop factor) / Time in minutes
Given:
Volume to be infused = 250 mL
Drop factor = 10 gtt/mL
Time = 30 minutes
Using the formula:
IV flow rate = (250 mL 10 gtt/mL) / 30 min
IV flow rate ≈ (2500 gtt) / 30 min
IV flow rate ≈ 83.33 gtt/min
Rounding to the nearest whole number, the nurse should set the manual IV flow rate to deliver 83 gtt/min.
Correct Answer is ["0.75"]
Explanation
To calculate the amount of heparin to administer, we can use the following formula:
Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))
Plugging in the given values:
Amount to administer (mL) = (7,500 units / 10,000 units/mL)
Now, let's solve for the amount to administer:
Amount to administer (mL) = (7,500 / 10,000) = 0.75 mL
So, the nurse should administer 0.75 mL of heparin subcutaneously.
