**Question:** Optimal operation theatre temperature should be

A. 20°C
B. 30°C
C. 22°C
D. 24°C

**Correct Answer:** D. 24°C

**Core Concept:**
The optimal operating theatre temperature plays a crucial role in maintaining patient comfort, preventing infection, and ensuring precise surgical outcomes. Maintaining the right temperature helps in maintaining the efficiency of surgical instruments, preventing blood coagulation issues, and reducing the risk of complications such as hypothermia or hyperthermia.

**Why the Correct Answer is Right:**
Temperature is a critical aspect in operating theatres as it directly impacts patient comfort, surgical precision, and infection control. The correct answer, 24°C, falls within the optimal range for maintaining these aspects.

**Why Each Wrong Option is Incorrect:**
A. 20°C is too cold, potentially causing patient discomfort, affecting coagulation, and increasing the risk of blood loss during surgery.
B. 30°C is too warm, which may lead to patient discomfort, increased sweating, and risk of fever and infection.
C. 22°C falls outside the optimal range, causing patient discomfort and potentially affecting surgical precision and instrument efficiency.

**Why Option D is Right:**
24°C strikes a balance between patient comfort, instrument efficiency, and infection control. This temperature aids in maintaining patient comfort, preventing sweating and shivering, ensuring precise surgical performance, and reducing the risk of infections.

**Clinical Pearl:**
24°C is a crucial aspect of aseptic technique and patient safety during surgery. By maintaining an appropriate operating theatre temperature, healthcare professionals can ensure better surgical outcomes, reduced patient discomfort, and minimized infection risks.
