A nurse is preparing to administer morphine 0.2 mg/kg IM to a client who weighs 99 lb. Available is morphine injection 10 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 ["0.9"]
First, you need to convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram, so 99 lb / 2.2 = 45 kg. The dose of morphine is 0.2 mg/kg, so for a client who weighs 45 kg, the dose would be 0.2 mg/kg * 45 kg = 9 mg. To calculate the number of mL the nurse should administer, you need to divide the dose of morphine (9 mg) by the concentration of the morphine injection (10 mg/mL). This gives you 9 mg / (10 mg/mL) = 0.9 mL. When rounded to the nearest tenth, this remains
0.9 mL. So, the nurse should administer 0.9 mL of morphine injection.

Correct Answer is ["100"]
Explanation
First, we need to determine how many milligrams of vancomycin are in each milliliter of the reconstituted solution:
1 g = 1,000 mg
If we reconstitute 1 g of vancomycin powder for injection in enough diluent to make a final volume of 200 mL, the concentration will be:
1,000 mg ÷ 200 mL = 5 mg/mL
Now, we can calculate how many milliliters of the reconstituted solution the nurse should administer to deliver 500 mg of vancomycin:
500 mg ÷ 5 mg/mL = 100 mL
Therefore, the nurse should administer 100 mL of the reconstituted vancomycin solution via intermitent IV
bolus.
