Texas Medical Assistant Certification Practice Test

What is a correct practice when administering medication via an ampule?

1. Use a needle that is longer than the ampule height.

2. Avoid shaking the ampule before withdrawal.

3. Ensure the liquid is clear before use.

4. Only use non-latex syringes to pull medication.

The correct answer is: Avoid shaking the ampule before withdrawal.

When administering medication via an ampule, it is essential to avoid shaking the ampule before withdrawal. Shaking can create bubbles or foam in the liquid, which may lead to inaccurate dosing or can introduce air into the syringe. This is particularly important when the medication is sensitive to agitation, as some substances can degrade or change properties when shaken. Therefore, gently swirling the ampule is often a better practice, as it allows for a more homogenous solution without the risk of creating bubbles. While other considerations such as ensuring the liquid is clear and using appropriate syringes are important aspects of medication administration, the practice of not shaking the ampule specifically addresses the integrity of the medication preparation and delivery, aligning with safe and effective medication administration protocols.
