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 B
Explanation
Choice A rationale
Using EPA registered insect repellants is a form of primary prevention, as it aims to prevent tick bites, which are the primary mode of transmission for Lyme disease.
Choice B rationale
Checking your clothing and body for ticks after being outdoors is a form of secondary prevention. If a tick is found and removed before it has had a chance to transmit the bacteria that cause Lyme disease, this can prevent the disease from occurring.
Choice C rationale
Wearing long-sleeved shirts and pants while outdoors is another form of primary prevention, as it can help prevent tick bites.
Choice D rationale
Notifying your health care provider if you notice a rash (especially a bull’s-eye rash, which is a common early symptom of Lyme disease) is a form of tertiary prevention, as it involves managing the symptoms of an existing disease.
Correct Answer is D
Explanation
Choice A rationale
Minimizing contact with a patient who is angry can create a barrier in the nurse-patient relationship. It’s important for nurses to address the patient’s anger and work through it rather than avoid it.
Choice B rationale
While it’s crucial to explain the importance of treatments, language barriers can make this difficult. The nurse should use a translator or other resources to ensure the patient fully understands.
Choice C rationale
Using clinical terminology can confuse patients who are not familiar with medical jargon. It’s better to use simple, understandable language.
Choice D rationale
Fulfilling promises builds trust and rapport. By allowing a patient to visit with family members, the nurse shows they are reliable and trustworthy.
