What is used to prevent exposure in operation theatre?
**Core Concept**
The question is testing the knowledge of infection control measures in the operating theater, specifically the use of personal protective equipment (PPE) to prevent exposure to bodily fluids and airborne pathogens.
**Why the Correct Answer is Right**
The correct answer is a type of PPE that covers the face and eyes to prevent respiratory droplets from entering the respiratory tract. This is crucial in preventing the transmission of airborne pathogens, such as tuberculosis, influenza, and COVID-19. The use of masks is mandated in the operating theater to protect both the surgical team and the patient from cross-contamination.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because gloves are used to prevent skin-to-skin contact with bodily fluids, not to prevent respiratory exposure.
**Option B:** This option is incorrect because gowns are used to prevent skin-to-skin contact with bodily fluids, not to prevent respiratory exposure.
**Option C:** This option is incorrect because eye protection, such as goggles or face shields, is used to prevent eye splashes from bodily fluids, not to prevent respiratory exposure.
**Clinical Pearl / High-Yield Fact**
In the operating theater, the use of a mask is mandated to prevent respiratory exposure to airborne pathogens. The Centers for Disease Control and Prevention (CDC) recommends the use of a face mask that covers the nose and mouth to prevent the transmission of airborne pathogens.
**Correct Answer: D. Surgical Mask**
