الإجابة: A. Quantitative anti-HBs antibody test
For a healthcare worker exposed to HBV who was previously vaccinated, the first step is to check the anti-HBs titre. If it is 10 mIU/mL or more they are protected; if it is lower they need a booster ± HBIG, depending on the source. So HBIG plus vaccine is not given before the response is known.

ليش صح
For a healthcare worker who was vaccinated, the first step is to test anti-HBs. A titre of 10 mIU/mL or more means protected with no further action; a lower titre needs a booster.

ليش غلط
A booster with or without HBIG is only for an anti-HBs below 10 mIU/mL, and HBIG depends on the source's status. It cannot be chosen before the titre is known.
