A nurse is preparing to administer nafcillin 2 g IV bolus. The nurse reconstitutes a vial of nafcillin to yield a final concentration of 250 mg/ml. How many m should the nurse administer? (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 ["8"]
Understanding the problem
We need to administer 2g of nafcillin.
The reconstituted solution has a concentration of 250 mg/mL.
We need to determine the volume to administer.
Step-by-step calculation
Convert grams to milligrams:
2 g = 2000 mg
Use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 2000 mg / 250 mg/mL
Calculate the volume:
Volume (mL) = 8 mL
Therefore, the nurse should administer 8 mL of the reconstituted nafcillin solution.

Correct Answer is ["24"]
Explanation
Calculations:
The heparin solution contains 25,000 units in 500 mL.
To deliver 1,200 units/hour, we need to find out how many mL will deliver this amount.
Set up a proportion:
25,000 units / 500 mL = 1,200 units / x mL
Cross-multiply:
25,000x = 1,200 x 500
Solve for x:
x = (1,200 x 500) / 25,000 = 24 mL/hr
The nurse should set the IV pump to deliver 24 mL/hr.
Correct Answer is ["60"]
Explanation
Understanding the problem
We need to administer 4 tablespoons of ibuprofen.
We need to convert tablespoons to milliliters.
Step-by-step calculation
1 tablespoon (tbsp) is equal to 15 milliliters (mL).
Therefore, 4 tbsp x 15 mL/tbsp = 60 mL
The nurse should administer 60 mL of ibuprofen.
