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.

Explanation
Choice A rationale
Paroxetine is a type of selective serotonin reuptake inhibitor (SSRI) that is commonly prescribed for the treatment of PTSD6. It works by increasing the levels of serotonin, a neurotransmitter that helps regulate mood, in the brain.

Correct Answer is B
Explanation
Choice A rationale
Community, Secondary prevention involves interventions that occur after the onset of disease or injury. This does not align with the ordinance, which is aimed at preventing the initiation of tobacco use.
Choice B rationale
Community, Primary prevention involves interventions that prevent the onset of disease or injury. This aligns with the ordinance, which is aimed at preventing the initiation of tobacco use among individuals under 18 years of age.
Choice C rationale
Individual, Secondary prevention would involve interventions targeted at individuals who have already started using tobacco, not at preventing the initiation of tobacco use.
Choice D rationale
Individual, Primary prevention would involve interventions targeted at individuals, not at the community level. The ordinance is a community-level intervention.
