Questions: 4. Which action minimizes the risk of introducing glass particles into the syringe when drawing medication from an ampule? A. Using minimal force to snap the neck of the ampule B. Using gauze to cover the top of the ampule when snapping it C. Using a filter needle or straw to draw the medication from the ampule D. Allowing the medication to settle after the ampule has been snapped open Which action might the nurse take when drawing up medication from an ampule? A. Hold the ampule upside down while inserting the filter needle. B. Inject air into the ampule before withdrawing the medication. C. Hold the ampule horizontally while inserting the filter needle. D. Expel air bubbles from the syringe while the filter needle is still inside the ampule.

The answer to the first question is C: Using a filter needle or straw to draw the medication from the ampule.

Explanation for each option: A. Using minimal force to snap the neck of the ampule - This action helps prevent shattering the ampule but does not specifically address the risk of glass particles entering the syringe. B. Using gauze to cover the top of the ampule when snapping it - This action helps protect the user from injury but does not prevent glass particles from entering the syringe. C. Using a filter needle or straw to draw the medication from the ampule - This is the correct action as filter needles are specifically designed to filter out glass particles, minimizing the risk of contamination. D. Allowing the medication to settle after the ampule has been snapped open - This does not prevent glass particles from entering the syringe.

The answer to the second question is C: Hold the ampule horizontally while inserting the filter needle.

Explanation for each option: A. Hold the ampule upside down while inserting the filter needle - This is not a common practice as it can lead to spillage and is not necessary for drawing up medication. B. Inject air into the ampule before withdrawing the medication - This is not applicable for ampules, as they are not sealed like vials and do not require air to be injected. C. Hold the ampule horizontally while inserting the filter needle - This is the correct action as it allows for better control and minimizes the risk of spillage while drawing up the medication. D. Expel air bubbles from the syringe while the filter needle is still inside the ampule - This is not recommended as it can lead to loss of medication and is not necessary for drawing up medication from an ampule.

In summary, using a filter needle or straw is the best way to minimize the risk of glass contamination, and holding the ampule horizontally is a practical method for drawing up medication.
