- A.
20 to 20 KHZ
- B.
1-2 MHZ
- C.
1-5MHz
- D.
5 - 10 MHz
Correct Answer
C. 1-5MHzExplanation
The frequency of AC usually used in E S U (Electrosurgical Unit) is in the range of 1-5MHz. This frequency range is commonly used in electrosurgery because it allows for precise cutting and coagulation of tissues. Higher frequencies provide better precision and control during surgical procedures, while lower frequencies may cause tissue damage or interfere with other medical equipment.

Example for Protective Zone is
- A.
Operation Theatre
- B.
OT Staff Room
- C.
ICU
- D.
Post Operative Ward
Correct Answer
B. OT Staff RoomExplanation
The correct answer is OT Staff Room. The OT staff room is considered a protective zone because it is a designated area where the operating theatre staff can relax, eat, and take breaks away from the sterile environment of the operating theatre. This helps to minimize the risk of contamination and infection in the operating theatre, ensuring a safe and hygienic environment for surgical procedures.Rate this question:

Example for Clean Zone is ......?
- A.
Induction Area
- B.
Operation Theatre
- C.
ICU
- D.
Post Operative Ward
Correct Answer
A. Induction AreaExplanation
The correct answer is Induction Area. The term "Clean Zone" refers to an area that is free from contaminants and is maintained to prevent the spread of infection. In a hospital setting, the Induction Area is typically the first area where patients are brought in for pre-operative procedures and preparation before entering the Operation Theatre. This area is kept clean to minimize the risk of introducing any contaminants into the sterile environment of the operating room. Therefore, the Induction Area is the most appropriate choice for a Clean Zone.Rate this question:

Example for Sterile Zone is...............?
- A.
Post Operative Ward
- B.
Scrub Area
- C.
ICU
- D.
Reception
Correct Answer
B. Scrub AreaExplanation
The correct answer is Scrub Area. In a healthcare setting, a sterile zone is an area that is free from any microorganisms to prevent infections. The scrub area is specifically designed for healthcare professionals to scrub and sanitize their hands and arms thoroughly before entering an operating room or any other sterile area. This helps to minimize the risk of introducing harmful bacteria or other contaminants into a sterile environment. The post-operative ward, ICU, and reception areas are not typically considered sterile zones as they may have a higher likelihood of containing microorganisms.Rate this question:

- B.
Anesthesia Machine
- C.
MRI
- D.
Dialysis Machine
Correct Answer
B. Anesthesia MachineExplanation
The correct answer is Anesthesia Machine. Anesthesia machines are specialized equipment used during surgical procedures to administer anesthesia to patients. These machines deliver a controlled mixture of gases and vapors to induce and maintain anesthesia, ensuring the patient remains unconscious and pain-free during the operation. Anesthesia machines are equipped with various components such as ventilators, monitors, and vaporizers to accurately deliver and monitor the anesthesia dosage. They play a crucial role in ensuring patient safety and comfort during surgery.Rate this question:

Generally used OT Lamp Type?
- A.
Fluorescent Lights
- B.
Halogen Lamp
- C.
Tungsten Lamp
- D.
LED Lamp
Correct Answer
D. LED LampExplanation
LED lamps are generally used as OT (Operating Theatre) lamps. LED lamps have become increasingly popular in medical settings due to their numerous advantages. They provide bright and focused illumination, allowing surgeons to clearly see the surgical area. LED lamps also have a longer lifespan, consume less energy, and generate less heat compared to other types of lamps. Additionally, LED lamps can be easily adjusted for color temperature, ensuring accurate visualization of tissues and reducing eye strain for medical professionals.Rate this question:

Commonly used Anesthetic agent?
- A.
Nitric Oxide
- B.
Nitrogen
- C.
Nitrous Oxide
- D.
Oxygen
Correct Answer
C. Nitrous OxideExplanation
Nitrous oxide is commonly used as an anesthetic agent in medical and dental procedures. It is a colorless and odorless gas that has analgesic and anxiolytic properties, making it effective in reducing pain and anxiety during surgeries or dental treatments. Nitrous oxide is also known as laughing gas, as it can induce a euphoric and relaxed state in patients. It is considered safe and well-tolerated, and its effects can be easily reversed, making it a popular choice for anesthesia.Rate this question:

Select the component which is the part of an Anesthesia Machine?
- A.
Stethoscope
- B.
Scavenging System
- C.
Pulse Generator
- D.
Thermostat
Correct Answer
B. Scavenging SystemExplanation
The scavenging system is a crucial component of an anesthesia machine. It is responsible for removing waste gases and vapors from the breathing circuit and preventing their release into the operating room. This system helps maintain a safe and controlled environment for both the patient and the healthcare providers. It typically includes a vacuum pump, tubing, and a waste gas collection system. By selecting the scavenging system as the correct answer, it shows an understanding of the importance of waste gas management in anesthesia delivery.Rate this question:

Intracellular instantaneous cell death occurs at what temperature?
- A.
At 70 degrees
- B.
At 60 degrees
- C.
At 90 degrees
- D.
At 120 degrees
Correct Answer
B. At 60 degreesExplanation
Intracellular instantaneous cell death occurs at 60 degrees. At this temperature, the cells are exposed to extreme heat, which leads to the denaturation and destruction of cellular proteins and other essential components. The high temperature disrupts the normal functioning of the cells, causing them to die rapidly.Rate this question:
