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?
Portal of entry
Infectious agent
Susceptible host
Reservoir
The Correct Answer is A
The chain of infection describes how an infection spreads based on six links of transmission: Infectious Agent, Reservoirs, Portal of Exit, Modes of Transmission, Portal of Entry, and Susceptible Host1. In this case, the client’s mouth is an example of a portal of entry, which is the route by which an infectious agent enters a new host1.

Correct Answer is A
Explanation
Answer: A. Wear a surgical mask when within 0.6 m (2 ft) of the client.
Rationale:
A) Wear a surgical mask when within 0.6 m (2 ft) of the client:
Droplet precautions are designed to prevent the spread of pathogens that are transmitted via large droplets, which can travel short distances. Wearing a surgical mask within 0.6 meters (2 feet) of the client is appropriate to protect against droplet transmission and is a key component of droplet precaution protocols.
B) Move the client to a positive airflow room:
Positive airflow rooms are used for clients who are immunocompromised and require protection from airborne pathogens, such as those in isolation for airborne precautions. Droplet precautions do not require positive airflow rooms, which are unnecessary for managing droplet-transmitted infections.
C) Place a surgical mask on the client when they leave their room:
While placing a surgical mask on the client is a good practice to prevent the spread of infection to others when they leave the room, it is not the primary action related to droplet precautions in the context of infection control. The primary measure is for healthcare workers to use appropriate personal protective equipment, such as masks, when interacting with the client.
D) Remove fresh flowers from the client’s room:
Removing fresh flowers is typically a measure for protecting immunocompromised patients from potential infections related to plant matter. This action is more relevant to patients on protective (reverse) isolation rather than droplet precautions.
