Final answer:
Skin storage media should be changed every 24 hours if skin is stored for more than 96 hours to maintain viability and prevent microbial growth.
Step-by-step explanation:
If skin is to be stored >96 hrs prior to processing, the skin storage media must be changed every 72 hours (option C). Skin storage media refers to the solution or substance in which the skin is stored to maintain its integrity. Changing the storage media regularly helps to prevent bacterial growth and maintain the quality of the stored skin.
If skin is stored for more than 96 hours prior to processing, the protocol for changing the skin storage media can vary based on specific laboratory protocols and the type of media used. However, a commonly accepted practice is to change the storage media every 24 hours. This frequency ensures that the nutrients and conditions remain optimal to preserve the skin's viability and prevent microbial growth. The regular change of media minimizes the risk of degradation and contamination, which can compromise the skin's usability for transplantation, research, or other purposes.
The correct answer to the question is: a. Every 24 hours.
