A nurse is caring for a 1-year-old child who has been hospitalized. Which of the following items in the child's room is a common source of health care-associated infection?

A. Aspirin should never be given to children with varicella due to the risk of Reye's syndrome, a serious and potentially fatal condition.
B. A warm blanket can increase the child's body temperature and discomfort. Cool compresses or baths are often recommended to relieve itching.

C. Varicella is a highly contagious airborne disease. Isolation precautions, including airborne precautions, are essential to prevent the spread of the virus.
D. Koplik spots are associated with measles, not varicella.

A. Pediculosis capitis, also known as head lice, is transmitted through direct head-to-head contact or by sharing personal items such as hats or combs. It is not transmitted via respiratory droplets, so droplet precautions are not required. Standard precautions for lice, such as treating the infestation and avoiding close contact, are appropriate.
B. Viral conjunctivitis, also known as pink eye, is primarily spread through direct contact with the eye secretions or contaminated objects. While viral conjunctivitis can be spread via contact, it does not require droplet precautions. Instead, proper hand hygiene and contact precautions are important to prevent the spread of the infection.
C. Hepatitis A is transmitted primarily through the fecal-oral route and not through respiratory droplets. Therefore, droplet precautions are not necessary. Standard precautions, including proper hand hygiene and safe food handling, are important for preventing the spread of hepatitis A.
D. Seasonal influenza (flu) is transmitted via respiratory droplets when an infected person coughs or sneezes. Droplet precautions are recommended for individuals with influenza to prevent the spread of the virus. This includes wearing masks, practicing good hand hygiene, and maintaining distance from others.
