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 A
Explanation
Choice A rationale
Chronic trauma refers to repeated exposure to traumatic events over a long period. Abuse and neglect since early childhood, as in the case of the adolescent in the question, is a clear example of chronic trauma.
Choice B rationale
Vicarious trauma occurs when an individual becomes traumatized not by directly experiencing a traumatic event, but by exposure to graphic or traumatic material as part of their work. This is not the case for the adolescent in the question.
Choice C rationale
Acute trauma results from a single, unexpected, and stressful event. This does not apply to the adolescent in the question, who has been subjected to abuse and neglect since early childhood.
Choice D rationale
Historical trauma refers to the cumulative emotional and psychological wounding of an individual or generation caused by a traumatic experience or event. This does not apply to the adolescent in the question.
Correct Answer is D
Explanation
Choice A rationale
While a family history of anxiety disorders can increase the risk of developing such disorders, positive childhood experiences can serve as protective factors, reducing the likelihood of developing an anxiety disorder.
Choice B rationale
Although a family history of cancer can cause stress and anxiety, especially if the client is recently unemployed and potentially struggling with financial instability, this does not necessarily mean they are most likely to develop an anxiety disorder. Unemployment can indeed be a source of stress, but it is not a direct cause of anxiety disorders.
Choice C rationale
Not graduating from high school or not completing the GED test can lead to lower socioeconomic status and fewer job opportunities, which can be stressful. However, these factors alone do not make someone most likely to develop an anxiety disorder.
Choice D rationale
A client who had multiple adverse childhood experiences and whose parents both have a history of anxiety disorders is most likely to develop an anxiety disorder. Adverse childhood experiences, such as abuse and neglect, are significant risk factors for the development of anxiety disorders later in life. Furthermore, having parents with a history of anxiety disorders suggests a possible genetic predisposition.
