A nurse is assisting with teaching a class about the roles and responsibilities of a case manager. Which of the following responsibilities should the nurse include?

Choice A reason: The reservoir is the environment or habitat where the infectious agent lives and multiplies. The client's mouth is not a reservoir, but rather a part of the susceptible host. The reservoir for hepatitis A is usually the feces of an infected person.

Choice B reason: The susceptible host is the person who is at risk of getting the infection. The client's mouth is not a susceptible host, but rather a part of the susceptible host. The susceptibility to hepatitis A depends on factors such as age, immunity, hygiene, and exposure.

Choice C reason: The portal of entry is the opening or route through which the infectious agent enters the susceptible host. The client's mouth is a portal of entry, as it is where the contaminated food entered the client's body and caused the infection. Hepatitis A is transmitted through the fecaloral route, meaning that the virus is ingested from contact with objects, food, or water contaminated by the feces of an infected person.

Choice D reason: The infectious agent is the microorganism that causes the infection. The client's mouth is not an infectious agent, but rather a portal of entry for the infectious agent. The infectious agent for hepatitis A is a virus that affects the liver and causes inflammation, jaundice, and fever.

Choice A reason: Sunbathing is a modifiable risk factor for developing a disease. Sunbathing exposes the skin to ultraviolet (UV) radiation, which can damage the DNA and cause skin cancer. Sunbathing can also cause premature aging, sunburn, and eye damage. The nurse should advise the client to limit sun exposure, use sunscreen, wear protective clothing, and avoid tanning beds.
Choice B reason: Family history is not a modifiable risk factor for developing a disease. Family history refers to the inherited traits and diseases that occur in the family. Family history can increase the risk of developing certain diseases, such as diabetes, heart disease, and cancer. The nurse should assess the client's family history and provide genetic counseling if needed.
Choice C reason: Genetics is not a modifiable risk factor for developing a disease. Genetics refers to the genes that determine the characteristics and functions of the body. Genetics can influence the susceptibility and resistance to certain diseases, such as cystic fibrosis, sickle cell anemia, and hemophilia. The nurse should educate the client about the role of genetics in health and disease, and refer the client to a genetic specialist if needed.
Choice D reason: Age is not a modifiable risk factor for developing a disease. Age refers to the number of years that a person has lived. Age can affect the body's ability to fight infections, heal wounds, and prevent chronic diseases. The nurse should monitor the client's age-related changes and provide age-appropriate care and interventions.
