For which of the following scenarios are two signatures required in the count book?

Two signatures are required in the count book during the process of adding a new medication refill. This practice is essential for ensuring accuracy and accountability in medication management. By requiring two signatures, the facility promotes thorough oversight and reduces the risk of errors or discrepancies in medication records. This procedural safeguard helps confirm that both parties involved acknowledge the addition of the refill, thus enhancing the integrity of the medication administration process.

In contrast, adding a new staff member, completing weekly inventory, or transferring medication to a different facility typically have different procedural requirements that may not necessitate the same level of dual verification. While these actions are also important, they aren't directly associated with the control and accuracy of medication refills, which involves transaction-specific accountability.
