A nurse is preparing to administer vancomycin 500 mg via intermitent IV bolus to a client. Available is vancomycin powder for injection 1 g vial. The nurse reconstitutes the powder for a final concentration of vancomycin 5 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 ["100"]
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.

Correct Answer is ["3.5"]
Explanation
First, we need to convert the child's weight from pounds to kilograms.
Since there are approximately 2.20462 pounds in 1 kilogram, 52 pounds is equivalent to 52/2.20462 =
23.587 kilograms.
The prescribed dose of digoxin is 7.5 mcg/kg/day, so for a child who weighs 23.587 kg, the total daily dose is 7.5 * 23.587 = 176.9 mcg/day.
Since the medication is available as a 50 mcg/mL elixir, the nurse should administer 176.9/50 = 3.538 mL/day.
Since the medication is to be administered once daily, the nurse should administer 3.538 mL per dose. Answer: 3.5
Correct Answer is ["1.8"]
Explanation
Step 1: Convert pounds to kilograms.
154 lb * (1 kg / 2.20462 lb) = 70 kg
Step 2: Calculate the total dose of gentamicin.
1 mg/kg * 70 kg = 70 mg
Step 3: Calculate the volume of gentamicin solution to administer.
70 mg / 40 mg/mL = 1.75 mL
Therefore, the nurse should administer 1.8 mL of gentamicin solution.
