TB Test Implementation and Benefits of Accreditation 3

Question 1

A public health department wants to implement an accredited two-step TST program for new healthcare workers. The primary purpose of the two-step process in this context is to:

Accepted Answer

Distinguish between a true TST conversion and a boosted reaction due to waning immunity

Answer

Two-step testing identifies individuals whose immune response to prior TB infection has waned; a boosted reaction on the second step is not a new conversion and should not trigger a full investigation.

Question 2

Under accreditation standards, which of the following scenarios would require a healthcare facility to immediately revise its TB testing program policy?

Accepted Answer

CDC publishes updated guidelines that change the recommended reading timeframe for TSTs

Answer

Accreditation requires facilities to keep their policies current with authoritative national guidelines; a CDC update to testing protocols mandates a policy review and revision.

Question 3

When implementing an accredited TB surveillance program, how should a facility handle an employee who refuses mandatory TB testing?

Accepted Answer

Follow the facility's documented policy, which must comply with applicable labor laws and accreditation standards

Answer

Accreditation requires facilities to have clear, written policies addressing test refusal that balance patient safety, employee rights, and relevant legal requirements.

Question 4

One measurable outcome that accreditation surveyors commonly use to evaluate the effectiveness of a TB testing program is:

Accepted Answer

The rate of TST conversions among current healthcare workers over the accreditation period

Answer

Monitoring TST conversion rates among current staff over time is a key quality metric that reveals whether TB exposure events are occurring within the facility and whether the program is effective.

Question 5

An accreditation standard requires that TST results be read between 48 and 72 hours after administration. A nurse reads a result at 96 hours and documents the induration as 8 mm. The correct action is to:

Accepted Answer

Document that the reading was performed outside the required window and repeat the TST

Answer

A TST read outside the 48–72 hour window is considered invalid under accreditation and CDC standards; the test must be repeated to ensure reliable results.
