Mary T. was admitted to a nursing home on May 1st. On July 4th, she was diagnosed with a skin infection. This infection is considered a ________________ infection.
Correct Answer: A
Rationale: The correct answer is 'nosocomial.' A nosocomial infection is defined as one that is not present upon admission to a healthcare facility but instead occurs during the patient's stay. In this case, since Mary was diagnosed with a skin infection after being admitted to the nursing home, it is considered a nosocomial infection. Nosocomial infections are a significant concern in healthcare settings, and infection control measures are in place to prevent their spread. Choices B, C, and D are incorrect. 'Systemic' refers to a condition affecting the entire body, not specific to a healthcare setting. 'Resident flora' and 'resident aura' are not commonly used terms in healthcare and do not relate to infections acquired in healthcare facilities.
