A nurse is preparing to administer foscarnet 60 mg/kg via intermittent IV bolus to a client who weighs 126 lb. Available is foscarnet 6,000 mg in 500 mL of 0.9% sodium chloride solution. How many ml should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["286"]

To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:

mL = (mg/kg x kg) / (mg/mL)

The client's weight in kilograms is:

126 lb / 2.2 lb/kg = 57.27 kg

The concentration of foscarnet in mg/mL is:

6,000 mg / 500 mL = 12 mg/mL

Plugging these values into the formula, we get:

mL = (60 mg/kg x 57.27 kg) / (12 mg/mL)

mL = (3,436.2 mg) / (12 mg/mL)

mL = 286.35 mL

Therefore, the nurse should administer 286 mL of foscarnet.

Correct Answer is ["60"]

Explanation

To calculate the infusion rate of lidocaine, we need to convert the dose from mg/min to mg/hr and then to mL/hr.

The prescribed dose is 4 mg/min, so the hourly dose is 4 x 60 = 240 mg/hr.

The concentration of the drug is 1 g in 250 mL, which is equivalent to 1000 mg in 250 mL or 4 mg in 1 mL.

Therefore, the volume per hour is 240 / 4 = 60 mL/hr.

Rounded to the nearest whole number, the nurse should set the IV pump to deliver 60 mL/hr.

Correct Answer is ["200"]

Explanation

To answer this question, we need to calculate the infusion rate of the IV pump. The formula for infusion rate is:

Infusion rate (mL/hr) = Volume (mL) / Time (hr)

We are given the volume of the solution, which is 50 mL, and the time of administration, which is 15 minutes or 0.25 hours. Plugging these values into the formula, we get:

Infusion rate (mL/hr) = 50 mL / 0.25 hr

Infusion rate (mL/hr) = 200 mL/hr

Therefore, the nurse should set the IV pump to deliver 200 mL/hr. This is the answer to the question.
