ATI LPN Fundamentals Exam 1 ( 59 Questions)
A nurse is caring for a client who acquired hepatitis A from consuming contaminated food. The client’s mouth is an example of which of the following links in the chain of infection?
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.
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.
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.
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: 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.
