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
The client must be calm and cooperative. This is the most important criterion for removing physical restraints. Restraints are used to prevent patients from causing harm to themselves or others. Once the patient is calm and cooperative, it indicates that the risk of harm has decreased. The goal is always to use the least restrictive measures and to remove restraints as soon as possible.
Choice B rationale
The provider who prescribed the restraints must be present to assess the client before the restraints can be removed. This is not necessarily true. While a provider’s order is required to initiate restraints, the decision to remove them can often be made by the nurse based on their assessment of the patient.
Choice C rationale
The client must verbalize remorse for their behavior. This is not a requirement for removing restraints. The primary concern is the safety of the patient and others, not whether the patient expresses remorse.
Choice D rationale
The client only verbalizes anger toward the staff. If the client is still expressing anger, it may not be safe to remove the restraints. However, verbalizing anger alone is not a sufficient reason to keep a patient in restraints.
Correct Answer is A
Explanation
Choice A rationale
Anxiety is considered transdiagnostic because it can manifest alongside other medical and psychiatric conditions. This means that a person with generalized anxiety disorder (GAD) may also have other conditions such as depression, heart disease, or gastrointestinal problems. The presence of anxiety can also exacerbate the symptoms of these other conditions.
Choice B rationale
Anxiety does not only manifest in the presence of recognized nonmodifiable risk factors. There are many factors that can contribute to the development of anxiety, including genetic predisposition, environmental factors, and personal experiences.
Choice C rationale
While there are recognized modifiable risk factors for anxiety, such as stress and lifestyle factors, anxiety does not only manifest in the presence of these factors. Anxiety is a complex condition that can be influenced by a variety of factors.
Choice D rationale
This statement is incorrect. As mentioned in Choice A, anxiety can and often does manifest alongside other medical and psychiatric conditions.
