Question 1

A healthcare worker is found to have a positive IGRA test during annual TB screening. Her previous baseline IGRA was negative. The NEXT step in management is:

Accepted Answer

Obtain a chest radiograph to rule out active tuberculosis disease

Answer

A new positive IGRA (conversion) requires a chest X-ray to exclude active TB disease before treating for latent TB infection.

Question 2

Which factor MOST increases the risk of HIV transmission following a percutaneous needlestick injury from an HIV-positive source patient?

Accepted Answer

Deep injury with a hollow-bore needle containing visible blood from a patient with high viral load

Answer

Deep injuries with hollow-bore needles contaminated with blood from high-viral-load patients carry the greatest transmission risk after percutaneous exposure.

Question 3

Healthcare workers with which condition should generally be excluded from caring for severely immunocompromised patients?

Accepted Answer

Active herpes zoster (shingles) with uncovered, weeping lesions

Answer

Active herpes zoster with open lesions poses a transmission risk to immunocompromised patients through direct contact.

Question 4

The MOST effective administrative control for reducing sharps injuries in a healthcare setting is:

Accepted Answer

Implementing a sharps safety device selection and evaluation program

Answer

Engineering controls such as safety-engineered sharps devices are more effective than behavioral interventions because they remove or reduce the hazard at the source.

Question 5

Under which circumstance may a healthcare worker with active pulmonary tuberculosis return to work?

Accepted Answer

After three consecutive negative sputum smears and clinical improvement on effective therapy

Answer

Return-to-work requires clinical improvement, effective therapy, and three consecutive AFB-negative sputum smears to ensure non-infectiousness.
