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.)

Answer and Explanation

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 ["1.5"]

Explanation

To calculate the amount of phenobarbital injection needed for each dose after the initial dose, we need to divide the prescribed dose (200 mg) by the concentration of the injection (130 mg/mL). This gives us:

200 mg / 130 mg/mL = 1.538 mL

To round this to the nearest tenth, we look at the hundredths place and see that it is 3, which is less than 5, so we round down and drop the rest of the digits. This gives us:

1.5 mL

Therefore, the nurse should administer 1.5 mL of phenobarbital injection per dose after the initial dose.

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.
