Which of the following clients is at risk for hepatitis A?

Hepatitis A is a viral infection that primarily spreads through the fecal-oral route, often associated with poor sanitation and contaminated food or water. Individuals traveling to or volunteering in developing countries are particularly at risk due to the potential exposure to contaminated water supplies and food handling practices that do not adhere to hygiene standards.

Volunteering in a developing country increases the likelihood of encountering situations where proper sanitation measures may not be followed, leading to a higher risk of Hepatitis A infection. Thus, this can put the client in a situation where they are more susceptible to contracting the virus.

Other options involve factors that do affect overall liver health or immunity but do not directly relate to the mode of transmission for Hepatitis A. Alcohol abuse is more associated with chronic liver conditions, while immunocompromised status increases the risk for a variety of infections, not specifically Hepatitis A. Family history of liver disease may indicate a predisposition to chronic liver conditions but does not increase the likelihood of exposure to the virus itself like travel to developing countries can.
