A nurse in a community health clinic is explaining to staff members that a mutation of influenza has increased the communicability of the virus.
Which of the following information should the nurse include to describe the effect of communicability of a virus?
The new mutation can survive in the environment and retain infectivity.
The new mutation causes more severe disease.
The new mutation spreads easier from one individual to another.
The new mutation requires a larger amount of the virus to cause disease.
The Correct Answer is C
Choice A rationale
While it’s true that some mutations can allow a virus to survive longer in the environment, this doesn’t necessarily increase the virus’s communicability, or its ability to spread from person to person.
Choice B rationale
A mutation that causes more severe disease can make an illness more dangerous, but it doesn’t necessarily make the virus more communicable. In fact, viruses that cause severe disease can sometimes be less communicable, because severely ill individuals are less likely to be moving around and spreading the virus.
Choice C rationale
The new mutation spreads easier from one individual to another. This is the definition of increased communicability. When a virus mutates in a way that allows it to spread more easily between individuals, this can lead to more cases of the disease, especially if the population is not immune to the new strain.
Choice D rationale
A mutation that requires a larger amount of the virus to cause disease would actually decrease the virus’s communicability. If more viral particles are needed to cause an infection, the virus would be less likely to spread from person to person.

Correct Answer is C
Explanation
Choice A rationale
While understanding the connection between thoughts, feelings, and behavior is a key component of many therapeutic approaches, it is not the primary focus of prolonged exposure therapy.
Choice B rationale
Encouraging patients to talk as a way of developing self-awareness is a common technique in various forms of therapy, but it does not specifically describe how prolonged exposure therapy works.
Choice C rationale
Prolonged exposure therapy involves helping patients safely and gradually face memories or situations related to their trauma that evoke fear. The goal is to reduce the avoidance of trauma-related memories and cues, which can decrease PTSD symptoms and improve quality of life.
Choice D rationale
While changing old behaviors and taking charge of one’s life can be a part of the therapeutic process, it does not specifically describe how prolonged exposure therapy works. I’m sorry, but I was unable to find specific information on the questions you provided from the websites you mentioned. However, I can provide general rationales for each choice based on my knowledge.
