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.

Answer and Explanation

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 C

Explanation

Choice A rationale
Clean drinking water is indeed crucial for preventing many diseases, especially those transmitted through the fecal-oral route or waterborne diseases such as cholera, typhoid, and hepatitis A1. However, it is not specifically targeted at diseases that are transmitted directly from person to person. Directly transmitted diseases are often spread through direct contact, such as person-to-person contact or droplet spread. Therefore, while clean drinking water is an essential aspect of public health, it is not the most effective method for preventing diseases that are transmitted directly.
Choice B rationale
Pest control is an important measure for preventing diseases transmitted by vectors, such as mosquitoes, ticks, and fleas. Diseases like malaria, dengue, Lyme disease, and plague are examples of vector-borne diseases. However, these diseases are not considered directly transmitted diseases. Direct transmission occurs when an infectious agent is transferred from a reservoir to a susceptible host by direct contact or droplet spread. Therefore, pest control, while important, is not the primary prevention method for diseases that are transmitted directly.
Choice C rationale

Isolation is one of the most effective methods for preventing the spread of directly transmitted diseases. When a person is isolated, they are separated from others to prevent the spread of communicable diseases. Isolation is used in healthcare settings to prevent the spread of infectious diseases that can be transmitted directly from person to person, such as tuberculosis, influenza, and COVID-191. Therefore, isolation is a key prevention method for diseases that are transmitted directly.
Choice D rationale
Proper sanitation, like clean drinking water, is crucial for preventing many diseases, particularly those transmitted through the fecal-oral route. Proper sanitation involves safely managing human waste and maintaining hygienic conditions through services such as garbage collection and wastewater disposal. While it is an essential aspect of public health, proper sanitation is not the most effective method for preventing diseases that are transmitted directly from person to person.

A. Secondary trauma B. Acute trauma C. Complex trauma D. Chronic trauma

Correct Answer is A

Explanation

Choice A rationale

Secondary trauma, also known as vicarious trauma or compassion fatigue, is a type of trauma that can occur in individuals who help or want to help others (like healthcare workers) experiencing a traumatic event. This can include feelings of fear, hopelessness, and difficulties in functioning, similar to those experienced by the person who underwent the actual trauma.
Choice B rationale
Acute trauma is typically associated with a single, severe traumatic event, not the ongoing stress of working in a high-stress environment like a Covid-19 unit.
Choice C rationale
Complex trauma refers to a type of trauma that occurs repeatedly and cumulatively, usually over a period of time and within specific relationships and contexts. It is not typically used to describe the experiences of healthcare workers in a pandemic.
Choice D rationale
Chronic trauma refers to the experience of multiple traumatic events. It is often used to describe situations such as ongoing child abuse, domestic violence, or war. It is not the most accurate term to describe the experiences of healthcare workers in a pandemic.
