Questions: If the controls fail, repeat the test. If they fail again: A. Call POCT office B. Enter comments C. Both A and B

The answer is C: Both A and B.

Explanation:

• Option A: Call POCT office - This is a correct action because if the controls fail repeatedly, it is important to notify the Point of Care Testing (POCT) office to address any potential issues with the testing equipment or procedures.
• Option B: Enter comments - This is also a correct action because documenting the failure and any steps taken is important for record-keeping and troubleshooting.
• Option C: Both A and B - This option is correct because both actions are necessary when the controls fail repeatedly. Calling the POCT office ensures that the issue is addressed, and entering comments provides a record of the incident.
