A nurse is preparing to administer phenytoin 75 mg PO. Available is phenytoin suspension 25 mg/5 mL. How many mL 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.)
Answer and Explanation

The Correct Answer is ["15"]

Step 1: Determine how many milligrams are in each milliliter of the suspension.

  • Total milligrams ÷ Total milliliters
  • 25 mg ÷ 5 mL = 5 mg/mL

Step 2: Determine how many milliliters are needed to administer 75 mg.

  • Desired milligrams ÷ Milligrams per milliliter
  • 75 mg ÷ 5 mg/mL = 15 mL

Correct Answer is D

Explanation

Choice A rationale:

Blood backing up in the IV tubing indicates a problem with the IV line, not necessarily infiltration.

Choice B rationale:

A long red streak up the arm could indicate phlebitis, not infiltration.

Choice C rationale:

Loose tape could cause the IV needle to dislodge, but it doesn’t directly indicate infiltration.

Choice D rationale:

Swelling around the IV site is a common sign of infiltration.

So, the correct answer is D. “My baby’s fingers are looking swollen.”.
