The nurse will select the intradermal route to administer a Tuberculin test. The test involves injecting tuberculin protein into the skin, and a positive result is indicated by a raised red area called an induration.
Step-by-step explanation:
The nurse will select the intradermal route to administer a Tuberculin test.
According to the information provided, the Tuberculin test involves injecting tuberculin protein into the skin. A positive test is indicated by a raised red area that is hard to the touch, called an induration. The induration is a result of the cellular infiltrate, an accumulation of activated macrophages.
The test is typically read 48-72 hours after the injection, and the size of the responding region is measured to determine the final result.
