Aclient is diagnosed with influenza and asks the nurse how the virus is transmitted. Which explanation by the nurse is accurate?

"Influenza is mainly transmitted through the bite of infected mosquitoes.”

"Influenza spreads through direct contact with infected animals.”

"Influenza is primarily transmitted through contaminated food and water.”

"Influenza is transmitted through respiratory droplets generated by coughing or sneezing.”

Answer and Explanation

The Correct Answer is D

Choice A rationale:

Influenza is not transmitted through the bite of infected mosquitoes. Influenza is a respiratory virus and spreads through respiratory droplets generated by infected individuals.

Choice B rationale:

Influenza is not primarily transmitted through direct contact with infected animals. Although some influenza strains can affect animals, the main mode of transmission to humans is from person to person through respiratory droplets.

Choice C rationale:

Influenza is not transmitted primarily through contaminated food and water. The virus is mainly spread through respiratory droplets produced when an infected person coughs, sneezes, or talks.

Choice D rationale:
This explanation is accurate. Influenza is transmitted through respiratory droplets generated by coughing or sneezing of an infected person. These droplets can be inhaled by individuals in close proximity, leading to infection. Proper hand hygiene and respiratory etiquette are essential to prevent the spread of influenza.

Correct Answer is D

Explanation

Rapid antigen test.

Choice A rationale:

Viral culture is a laboratory test used to grow and identify viruses, including influenza. While it is sensitive and specific, it is not suitable for rapid diagnosis as it may take several days to produce results.

Choice B rationale:

Polymerase chain reaction (PCR) is a highly sensitive and specific test that can detect the genetic material of the influenza virus. It is suitable for confirmation of the diagnosis, but it may take a few hours to produce results, so it is not as rapid as the correct answer.

Choice C rationale:

Serology involves testing for antibodies produced by the body in response to the influenza virus. While it can confirm past infection, it is not suitable for rapid diagnosis of acute influenza because it may take days to weeks for antibodies to develop.

Choice D rationale:

The rapid antigen test is a quick diagnostic test that detects specific proteins (antigens) on the surface of the influenza virus. It can provide results within 15-30 minutes, making it useful for rapid screening. However, it is less sensitive than PCR and may produce false-negative results in some cases. Despite this limitation, it is valuable in certain settings where immediate diagnosis is crucial for patient management and infection control.

A. "The incubation period of influenza ranges from 2 to 5 days.” B. "The incubation period of influenza is about 1 week.” C. "The incubation period of influenza can last up to 2 weeks.” D. "The incubation period of influenza is usually less than 24 hours.”

Correct Answer is A

Explanation

Choice A rationale:

"The incubation period of influenza ranges from 2 to 5 days." This is the correct response. The incubation period of influenza, which refers to the time between exposure to the virus and the onset of symptoms, typically ranges from 2 to 5 days.

Choice B rationale:

"The incubation period of influenza is about 1 week." This is incorrect. The incubation period of influenza is shorter than one week.

Choice C rationale:

"The incubation period of influenza can last up to 2 weeks." This is incorrect. While some other viral illnesses may have longer incubation periods, influenza usually has a shorter incubation period.

Choice D rationale:

"The incubation period of influenza is usually less than 24 hours." This is incorrect. The incubation period of influenza is longer than just a few hours; it typically takes a couple of days before symptoms appear.
