Questions: Which of the following statements about postoperative care records is false? Postoperative care records should be maintained at least a year after the death of an animal that is regulated by the USDA. Written postoperative care records are not necessary, as long as proper care is provided and treatments are administered. For rodents, individual postoperative care records are not usually maintained. Daily observations are usually recorded during the postoperative period.

The answer is the second one: Written postoperative care records are not necessary, as long as proper care is provided and treatments are administered.

Explanation for each option:

1. Postoperative care records should be maintained at least a year after the death of an animal that is regulated by the USDA.
   This statement is true. The USDA requires that records related to the care and use of regulated animals be maintained for a specific period, often at least a year after the animal's death.

2. Written postoperative care records are not necessary, as long as proper care is provided and treatments are administered.
   This statement is false. Written records are essential for ensuring that proper care is documented and can be reviewed for compliance and quality assurance purposes. They provide a verifiable account of the care provided.

3. For rodents, individual postoperative care records are not usually maintained.
   This statement is true. In many research settings, individual records for rodents may not be maintained due to the large number of animals and the nature of the studies. Instead, group records or summary logs may be used.

4. Daily observations are usually recorded during the postoperative period.
   This statement is true. Daily observations are typically recorded to monitor the animal's recovery and to ensure any complications are promptly addressed.

In summary, the false statement is the second one, as written records are indeed necessary for proper documentation and compliance.
