The risk of contracting Hepatitis B through a needlestick injury from a chronic carrier is increased when the patient's serology report indicates the presence of:

HBsAg
HBcAg
HBeAg
Anti-HBs

The correct answer is: HBeAg

The serology report measures the presence of certain antibodies and antigens in the blood. In the case of Hepatitis B, the presence of HBeAg indicates an active infection with a high level of hepatitis B virus in the blood. This significantly increases the risk of contracting the virus through a needlestick injury. In contrast, options A, B, and D do not necessarily indicate an active infection and therefore would not increase the risk of contracting Hepatitis B.
