Final Answer:
According to AATB standards, the minimum recommended weight for heart valve donors is 7 lbs.
Step-by-step explanation:
The American Association of Tissue Banks (AATB) establishes standards for tissue donation, including heart valves. In the context of heart valve donors, the minimum recommended weight, as per AATB standards, is 7 lbs. This criterion ensures that potential donors meet a baseline requirement for the viability and quality of harvested heart valves. The weight threshold is indicative of a certain level of development and maturity, contributing to the suitability of the donated tissue for transplantation. Adhering to these standards is crucial for maintaining the integrity and safety of tissue transplantation procedures.
The correct answer is option C - 7 lbs.
