Final answer:
To administer a TB test in a community center, the nurse should use a 25-gauge needle for intradermal injection, instruct clients to return for reading the test in 48 hours, and perform the test on clients with active respiratory symptoms or potential exposure to TB.
Step-by-step explanation:
The nurse should take the following action when preparing to administer a TB test to multiple clients:
- Use a 25-gauge needle for intradermal injection: The Mantoux skin test for tuberculosis involves injecting tuberculin protein derivative into the skin, and using a 25-gauge needle allows for precise intradermal injection.
- Instruct clients to return for reading the test in 48 hours: The tuberculin test should be read in 48-72 hours after injection. A positive result is indicated by redness, swelling, or hardness, and the size of the reacting area is measured to determine the final result.
- Perform the test on clients with active respiratory symptoms only: The test is used to screen for potential TB exposure, so it should be performed on clients who exhibit active respiratory symptoms or have been exposed to TB.
