1323 year old intravenous drug user, HIV-positive, on HART (antiretroviral) treatment as hospitalised in infectious department with jaundice.

What is the risk to the nurse and what should be done?- AThe patient has acute hepatitis A, without much risk, controlled HIF infection, no risk of transmission
- BThe patient has acute hepatitis A. without much risk. controlled HIF infection but the nurse held a 28-day course with HART, insignificant risk of hepatitis C
- CThe patient has acute hepatitis A, without much risk, controlled HIF infection but the nurse held a 28-day course with HART, nevertheless monitoring tor HCV and HIF in the next six months

24To prove the VHA is looking for
- Aviral antigens in fecal samples
- Banti HAV IgM in serum
- CHBsAg in serum
25Serotogical markers of acute viral hepatitis B (VHB) are
- AHBsAg + anti HbC IgM
- BHBsAg + anti HbC IgG
- CHBcAg + anti HBc
26Clinical and laboratory indicators of threatening coma are
- Areduced haemostatic factors, low fibrinogen
- Bleucopenia and high fibrinogen
- Clymphocytosis and accelerated ESR
27Frequently out of the VHA is a

- Cacute liver failure
28The incubation period of the VHB is
- A10-30 days
- B40-180 days
- C3-90 days
