A nurse is preparing to administer 0.9% sodium chloride 750 mL IV to infuse over 2 hr. 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 ["375"]
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.

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 ["0.3"]
Explanation
To calculate the dose of cefazolin for a neonate, first multiply the weight by the dosage per day: 5 kg x 40 mg/kg/day = 200 mg/day. Then divide by the number of doses per day: 200 mg/day / 2 doses/day = 100 mg/dose. Next, use the formula D/H x Q to find the volume to administer, where D is the dose, H is the strength of the solution, and Q is the quantity of the solution. Plug in the values: 100 mg / 330 mg/mL x 1 mL = 0.3 mL. Round to the nearest tenth: 0.3 mL. Therefore, the nurse should administer 0.3 mL of cefazolin per dose.
