The nurse is preparing a medication that comes in an ampule.Which action by the nurse is appropriate?

A) Tapping the ampule so fluid moves from the bottom of the ampule to the neck
B) Avoiding inversion of the ampule after opening to prevent spillage of the medication
C) Using a filter needle long enough to reach the bottom of the ampule
D) Guiding the needle against the rim of the ampule to access the medication

Filter needles filter out any fragments of glass,and reaching the bottom of the ampule allows the medication to be completely withdrawn.The top of the ampule is tapped to move the fluid from the neck into the bottom of the ampule,where it is withdrawn.The ampule is held upside down or is set on a flat surface for withdrawal of the medication.The medication will not spill from the ampule after opening unless the needle tip or shaft touches the rim.The rim is considered contaminated and should not be touched by the needle.
