A nurse is preparing to administer methylprednisolone sodium succinate 30 mg/kg via intermittent IV bolus to a client who weighs 169 lb. Available is methylprednisolone sodium succinate 125 mg/mL. 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 ["18"]

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.

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 ["800"]

Explanation

This choice is correct because it is the result of dividing the volume of the bolus (200 mL) by the time of the infusion (15 minutes) and multiplying by 60 minutes per hour. The formula for calculating the rate of the pump is:

Rate = (Volume/Time) x 60

Therefore, the rate of the pump is:

Rate = (200 mL/ 15 min) x 60 = 800 mL/hr
