a healthcare - associated infection (traditionally known as a nosocomial infection) is
only a result of surgery
always caused by medical personnel
always caused by pathogenic bacteria
acquired during the course of hospitalization
always present, but is inapparent at the time of hospitilization

Explanation:

• For the first question:
• Vaccination helps build immunity in individuals, reducing the number of susceptible people in a population.
• Quarantine isolates infected individuals to prevent the spread to others.
• Handwashing removes pathogens from hands, reducing the chance of transmission.
• Since all these methods are valid for controlling infectious - disease spread, "All of the choices are correct" is the right answer.
• For the second question:
• A healthcare - associated infection (nosocomial infection) is defined as an infection that is acquired during the course of hospitalization.
• It is not only a result of surgery (can occur due to other medical procedures or hospital - environment exposure).
• It is not always caused by medical personnel (can be due to hospital equipment, other patients' flora etc.).
• It is not always caused by pathogenic bacteria (can be viruses, fungi etc.).
• And it is not always present at the time of hospitalization (if it were, it would not be a healthcare - associated infection).

Answer:

• First question: B. All of the choices are correct
• Second question: D. acquired during the course of hospitalization
