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 ["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.
Correct Answer is ["15"]
Explanation
To answer this question, we need to calculate the dose of esmolol in mcg/kg/min, then convert it to mg/hr, and then use the formula:
mL/hr = (dose in mg/hr) x (volume in mL) / (concentration in mg)
First, we convert the client's weight from pounds to kilograms:
110 lb x 1 kg / 2.2 lb = 50 kg
Next, we multiply the client's weight by the prescribed dose to get the dose in mcg/min: 50 kg x 50 mcg/kg/min = 2500 mcg/min
Then, we divide the dose in mcg/min by 1000 to get the dose in mg/min: 2500 mcg/min / 1000 = 2.5 mg/min
Finally, we multiply the dose in mg/min by 60 to get the dose in mg/hr: 2.5 mg/min x 60 = 150 mg/hr
Now, we can use the formula to find the infusion rate in mL/hr:
mL/hr = (150 mg/hr) x (250 mL) / (2500 mg)
mL/hr = 15
Therefore, the nurse should set the IV pump to deliver 15 mL/hr.
