Deck 17: Hepatitis

Question 1

Is it a concern that Lily worked with and served raw fish? She did not serve the fish from Southeast Asia that she was given; she ate all of that herself.
a.It is a concern for all her customers because this always spreads from person to person even if they did not eat any raw food.

d.none of the above

Question 5

A car accident occurred right outside the hospital. Your friend Eddie who works in administration ran to the accident victim. He pressed a bandana over the cut on the victim's arm that was spurting blood until the emergency crew came. The victim was positive for hepatitis Be antigen. Is Eddie, who has not been vaccinated, at risk?
a.Yes, HBeAg indicates that the patient is infectious.
b.No, hepatitis E is spread only through fecal oral contact.
c.No, HBeAg is present during recovery, so the patient has hepatitis but is not very infectious.
d.Yes, but he can take penicillin to prevent the infection
