A nurse is caring for a school-age child who witnessed a violent crime.
Each time the child recalls the event, the details differ from previous recollections. Which of the following trauma-related symptoms is the child experiencing?

Choice A rationale
Having a mother who had you when she was in high school does not necessarily indicate a protective factor. It could mean that the mother was not fully prepared for the responsibilities of parenthood, which could have led to a less stable upbringing.
Choice B rationale
Having parents in the military and moving a lot since birth can be a source of stress and instability for a child. Constantly changing environments and having to adapt to new schools and make new friends can be challenging and anxiety-inducing.
Choice C rationale
Having a supportive and understanding teacher can be a significant protective factor for an adolescent with an anxiety disorder. A teacher who listens well can provide a safe and supportive environment for the student to express their feelings and concerns, which can help alleviate anxiety.
Choice D rationale

Having a sibling with health problems can be a source of stress and anxiety for a child. The parents’ attention might be primarily focused on the sibling’s health issues, which could lead to feelings of neglect or added pressure to be the “healthy” or “problem-free” child.

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.
