Pharmacological and Parenteral TherapiesQuestion 342 of 2368

A nurse draws medication from an ampule using a blunt fill filter needle. What should the nurse do before injecting the client?

  1. Replace the filter needle with a needle suited to the injection
  2. Inject with the filter needle to save time
  3. Tap the filter needle on the ampule to clear glass
  4. Keep the filter needle and change only the plunger
Show answer

Correct answer: Replace the filter needle with a needle suited to the injection

A filter needle only keeps glass out of the syringe. It is never used to inject, so it is swapped for the right size and gauge.
