Final answer:
Antibiotics used in surgery often come in powdered form and must be reconstituted with a sterile fluid to prepare them for patient use.
Step-by-step explanation:
Many antibiotics used in surgery come in powdered form and must be reconstituted. Antibiotics are powerful medicines that fight bacterial infections and are crucial in preventing infections during and after surgery. The powdered form of antibiotics is generally designed to increase the stability, decrease toxicity, and offer a longer shelf-life. These powdered antibiotics need to be reconstituted, or mixed with a specific liquid, usually sterile water or a saline solution, according to strict protocols to ensure the correct dosage and potency is achieved for use in patients.
