Question

The Operation theatre is planned on the concept of zones, predicted on the types of activities, patterns of circulation and degree of sterility to be maintained. They are:
A. Disposal zone
B. Protective zone
C. Autonomous zone
D. Sterile zone
Choose the correct answer from the options given below:

• A. A, B and D only
• B. A and B only
• C. A, B and C
• D. B, C and D only

Hint:

Think of the OT zones as a series of airlocks with increasing levels of cleanliness: you start in the \textbf{Protective} zone, move to the \textbf{Clean} zone, then the ultra-clean \textbf{Sterile} zone, and exit with used materials through the \textbf{Disposal} zone.

Answer 1

The Correct Option is A

Step 1: Recall the standard zoning concept for an Operation Theatre complex. Step 1: An OT complex is designed with zones of increasing cleanliness to minimize the risk of infection. The typical model includes four zones.
Step 2: Identify the standard zones.
Step 2: The four standard zones are:

Protective Zone (or Outer Zone): The entrance area where staff and patients enter. Street clothes are permitted here.
Clean Zone (or Semi-Restricted Zone): Area for pre-operative preparations, storage of clean supplies, and staff changing rooms. Requires scrubs and caps.
Sterile Zone (or Restricted Zone): The actual operating room where surgery is performed. Requires full sterile attire.
Disposal Zone (or Dirty Corridor): The exit corridor for used instruments, linen, and waste.
Step 3: Evaluate the options provided.
Step 3: The list includes (A) Disposal zone, (B) Protective zone, and (D) Sterile zone, which are all standard parts of the OT zoning concept. (C) Autonomous zone is not a standard term in this context. Therefore, A, B, and D are the correct components.
