An occupational health nurse is interpreting the results of a tuberculin skin test for a group of clients who received the test 48 hr ago. Which of the following clients should the nurse identify as having a positive test result?
A client whose injection site is scabbed
A client whose injection site is firm and measures 3 mm (0.1 in)
A client whose injection site has an elevated area measuring 15 mm (0.6 in)
A client whose injection site is ecchymotic
The Correct Answer is C
Choice A Reason:
A client whose injection site is scabbed is incorrect. Scabbing at the injection site does not provide information about the presence or absence of induration. It doesn't contribute to interpreting the test result directly.
Choice B Reason:
A client whose injection site is firm and measures 3 mm (0.1 in) is incorrect. A measurement of 3 mm of induration is generally considered a negative result for most individuals, including those without any risk factors for tuberculosis (TB).
Choice C Reason:
A client whose injection site has an elevated area measuring 15 mm (0.6 is correct. An area of induration measuring 15 mm or more is considered positive in individuals with no known risk factors for TB.
Choice D Reason:
A client whose injection site is ecchymotic is incorrect. Ecchymosis (bruising) at the injection site is not relevant to the interpretation of the tuberculin skin test. It does not contribute to determining a positive or negative result.

Correct Answer is A
Explanation
Choice A Reason:
Checking the client for ecchymosis is appropriate. Thrombocytopenia increases the risk of bleeding and bruising, so monitoring for ecchymosis (bruising) is essential to detect any signs of bleeding. Ecchymosis can occur more easily in individuals with low platelet counts.
Choice B Reason:
Initiating protective isolation for the client is typically unnecessary solely due to thrombocytopenia. Protective isolation is generally for clients with conditions that compromise their immune system or make them more susceptible to infections.
Choice C Reason:
Administering ibuprofen for a mild headache might not be advisable in someone with thrombocytopenia because ibuprofen can affect platelet function and potentially increase the risk of bleeding.
Choice D Reason:
Instructing the client to shave with a disposable razor isn't recommended because using a sharp blade can increase the risk of cuts and bleeding in someone with a low platelet count. Using an electric razor or avoiding shaving might be safer options to prevent injury and bleeding.
Correct Answer is D
Explanation
Choice A Reason:
"I can have clear liquids up to 3 hours before the procedure." This is incorrect. Clients are usually instructed to be NPO (nothing by mouth) for a certain period before the procedure, typically 6-8 hours, to reduce the risk of aspiration.
Choice B Reason:
"I can eat as soon as the procedure is completed." This is incorrect. Clients should not eat or drink until the gag reflex returns, which can take a few hours after the procedure.
Choice C Reason:
"I will receive an injection of radioactive material prior to having the procedure.” This is incorrect. An injection of radioactive material is not part of a bronchoscopy. This might be confused with a different diagnostic procedure, such as a PET scan.
Choice D Reason:
"I might have blood-tinged sputum after the procedure." This statement indicates an understanding of the teaching. It is common for clients to have a small amount of blood-tinged sputum following a bronchoscopy due to the irritation caused by the procedure.
