Correct Answer is ["3"]

Explanation

Step 1 is to determine the total amount of medication needed, which is 750 mg. Step 2 is to convert the medication needed into mL using the medication’s concentration. So, 750 mg ÷ (250 mg/5 mL) = 15 mL.

So, the correct answer is 15 mL.

Correct Answer is ["10"]

Explanation

Step 1: Determine the Medication Concentration

  • The total amount of medication in the solution is 250 mg.
  • The total volume of the solution is 5 mL.
  • To find the concentration per mL:
    250 mg ÷ 5 mL = 50 mg/mL

Step 2: Determine the Required Volume

  • The prescribed dose is 500 mg.
  • To find the volume needed:
    500 mg ÷ 50 mg/mL = 10 mL

Thus, the nurse should administer 10 mL of the solution to deliver the required 500 mg dose.
