A nurse is preparing to administer methylprednisolone 30 mg/kg via IV bolus to a client who weighs 184 lb. Available is methylprednisolone 125 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["20.1"]
To calculate the dosage of methylprednisolone, first convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds.
The client weighs 184 pounds, which is approximately 83.64 kilograms (184 lb / 2.2).
Next, multiply the client's weight in kilograms by the dosage prescribed, which is 30 mg/kg.
This results in a total dosage of 2509.2 mg (83.64 kg * 30 mg/kg).
Finally, divide the total dosage by the concentration of the available medication to find out how many milliliters to administer.
The available medication is 125 mg/mL,
so you would administer 20.07 mL (2509.2 mg / 125 mg/mL).
Rounded to the nearest tenth, the nurse should administer 20.1 mL.

Correct Answer is ["100"]
Explanation
To calculate the IV pump rate in mL/hr, you need to divide the volume of the solution in mL by the infusion time in hr. In this case, the formula is 100 mL / 1 hr = 100 mL/hr.
Therefore, the nurse should set the IV pump to deliver 100 mL/hr of metronidazole.
Correct Answer is ["375"]
Explanation
To answer this question, you need to use the formula: rate (mL/hr) = volume (mL) / time (hr). Plug in the given values and you get: rate = 750 / 2.
Simplify and you get: rate = 375.
Therefore, the nurse should set the IV pump to deliver 375 mL/hr.
