Which of the following infections would the nurse recognize as being a health care-associated infection?

A. A person with diabetes who requires hospitalization for cellulitis: This condition likely originated outside of the hospital, making it a community-acquired infection. Health care-associated infections are defined as those that occur after exposure within a health care setting, typically 48 hours or more after admission. B. Chronic urinary tract infection for a homebound patient: Although chronic, this infection is not acquired in a health care facility such as a hospital or clinic. HAIs are specific to infections that develop during hospitalization or while receiving care in a medical environment. C. A sexually transmitted infection in a healthy young adult: STIs are spread through intimate contact and are considered community-acquired infections. They are not contracted in health care settings and do not meet the criteria for being classified as health care-associated infections. D. Pneumonia in a hospitalized patient: If pneumonia develops 48 hours or more after admission, it is considered a health care-associated infection. It typically results from exposure to pathogens in the hospital environment, often related to procedures, equipment, or contact with staff.
