Final answer:
The correct answer is option c) filter needle. Filter needles are essential for preventing glass shard contamination when drawing liquid from an ampule.
Step-by-step explanation:
A filter needle is used when removing liquid from an ampule to avoid any microscopic glass shards. When drawing medication or liquids from an ampule, which often requires breaking the glass top, the use of a filter needle helps to ensure that no small pieces of glass contaminate the liquid being drawn into the syringe.
Traditional pipettes, burets, and graduated cylinders are crucial in the accurate measurement and transfer of liquids in a laboratory setting. The same attention to precision and safety is required when handling medications in a healthcare environment. Especially in clinical settings, maintaining aseptic techniques is vital to prevent contamination. These techniques include holding tubes or bottles at an angle during transfers and potentially passing them through a flame to minimize airborne contaminants. Another measure for maintaining the purity of a solution is the use of membrane filters or HEPA filters, which have their own specific clinical and laboratory applications.
Understanding and applying these methods, including the use of a filter needle, are critical to ensure the safety and efficacy of the medications administered to patients.
