What is the most common source of nosocomial infections?

  1. Surgical instruments

  2. Healthcare environment

  3. Patient's home

  4. Public transportation

The correct answer is: Healthcare environment

Nosocomial infections are acquired while being admitted to a hospital or medical facility. These types of infections can be caused by a variety of factors, such as surgery, exposure to antibiotics, or weakened immune systems. Even though surgical instruments, such as contaminated needles or surgical tools, can be sources of infection, the most common source is actually the healthcare environment itself. This includes contaminated surfaces, medical equipment, and even health care workers' hands. Therefore, the other options, patient's home and public transportation, are not as likely to be common sources of nosocomial infections as the healthcare environment.
