Correct Answer is ["94"]

Explanation

Step 1 is to calculate the rate of infusion. The formula is total volume ÷ total time. So, (750 mL ÷ 8 hr) = 93.75 mL/hr. Rounding to the nearest whole number gives 94 mL/hr.

So, the correct answer is 94 mL/hr.

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.
