A nurse is preparing to administer metronidazole 500 mg by intermittent bolus over 60 min. Available is metronidazole 500 mg in 100 ml 0.9% sodium chloride. The nurse should set the IV pump to deliver how many mL/hr?
(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 ["100"]
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 ["20.1"]
Explanation
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 ["1"]
Explanation
To answer this question, you need to convert the dosage of fentanyl from micrograms (mcg) to milligrams (mg). One milligram is equal to 1000 micrograms, so 50 mcg is equal to 0.05 mg. Then, you need to use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 0.05 mg, H is 0.05 mg/mL, and Q is the volume in milliliters. Plugging these values into the formula, you get:
0.05 mg / 0.05 mg/mL x Q
Q = 1 mL
Therefore, the nurse should administer 1 mL of fentanyl per dose.
