A diabetic client is being screened for tuberculosis. The nurse administers the tuberculin skin test. Instructions related to the skin test should include:

1. The client must return within 24 to 36 hours to have the test assessed.
2. A positive reaction to the skin test is based upon redness around the injection site.
3. An induration area of 15 mm or greater is significant in this client.
4. An induration area of 10 mm or more is considered positive in this client.

ESSAYBID ANSWER

Answer: 4
Explanation: 4. For persons with a high risk of disease such as those with diabetes, 10 mm ore more induration is considered positive. The skin test is read within 48 to 72 hours of administration. A positive or significant reaction is based on the degree of induration, not the redness around the site. In a person with normal immune function an area of induration of 15 mm or greater is considered significant.
