A nurse is educating parents about measles prevention. Which of the following statements accurately reflects how measles is transmitted?
Measles is transmitted through contaminated water sources.
Measles is transmitted through contact with infected animals.
Measles is transmitted through respiratory droplets and person-to-person contact.
Measles is transmitted through exposure to contaminated food.
The Correct Answer is C
Measles is transmitted through respiratory droplets and person-to-person contact.
Choice A rationale:
Measles is not transmitted through contaminated water sources. It is a highly contagious viral infection that primarily spreads through respiratory droplets when an infected person coughs or sneezes.
Choice B rationale:
Measles is not transmitted through contact with infected animals. It is a human-specific virus and does not infect animals.
Choice C rationale:
This is the correct choice. Measles is primarily transmitted through respiratory droplets when an infected person coughs or sneezes. It can also spread through direct contact with respiratory secretions or airborne particles.
Choice D rationale:
Measles is not transmitted through exposure to contaminated food. The virus is not foodborne, and the main mode of transmission is person-to-person through respiratory droplets.

Correct Answer is C
Explanation
Choice A rationale:
Providing oral care with mouthwash containing alcohol is not appropriate for a client with suspected measles and Koplik spots in the mouth. Alcohol-based mouthwashes can be irritating to the mucous membranes and may exacerbate the symptoms.
Choice B rationale:
Offering spicy and acidic foods to encourage appetite is not appropriate for a client with measles and Koplik spots. Spicy and acidic foods may cause discomfort and irritation to the oral mucosa, making the condition worse.
Choice C rationale:
Rinsing the mouth with warm saline solution is the correct nursing intervention for a client with measles and Koplik spots. Saline solution helps soothe the irritated mucous membranes and can aid in reducing discomfort.
Choice D rationale:
Applying topical corticosteroid ointment to the spots is not appropriate for a client with measles and Koplik spots. Corticosteroids can suppress the immune response, which may interfere with the body's ability to fight off the measles virus.
Correct Answer is C
Explanation
Choice A rationale:
Nucleoprotein (N) and phosphoprotein (P) are not responsible for viral entry and fusion in measles infection. These proteins are involved in viral replication and assembly, not the initial entry into host cells.
Choice B rationale:
Matrix protein (M) and large protein (L) are not responsible for viral entry and fusion in measles infection. The matrix protein plays a role in the assembly and structure of the virus, while the large protein is involved in viral replication and transcription.
Choice C rationale:
Fusion protein (F) and hemagglutinin protein (H) are the primary proteins responsible for viral entry and fusion in measles infection. The hemagglutinin protein allows the virus to bind to specific receptors on host cells, while the fusion protein facilitates the fusion of the viral envelope with the host cell membrane, allowing the virus to enter the cell.
Choice D rationale:
Nucleoprotein (N) and matrix protein (M) are not directly involved in viral entry and fusion. Nucleoprotein plays a role in protecting the viral RNA, and the matrix protein is involved in viral assembly and budding.
