Which step involves preparation for swab testing?

• A. Review PSV-35 with the client
• B. Confirm if client used any prescribed or over the counter medication or alcohol
• C. Sign out of UA/Swab container and label with client's name and SID
• D. Preparation - For swab, instruct client, to have no food or drink within 10 minutes of testing

Answer: (D)

The step being tested focuses on getting the test ready by ensuring the client is in the right condition for accurate sampling. Instructing the client to have no food or drink within 10 minutes of testing directly prepares the mouth for the swab, reducing contamination or residues that could skew the results. This pre-test instruction helps ensure the sample collected is representative and reliable.

The other actions fit different parts of the process: reviewing a form with the client is about information or consent, checking substances relates to interpreting results or the broader testing context, and labeling or signing out the container is a post-collection documentation step. They’re important, but they aren’t the specific preparation step for the swab itself.
