Free COST Aseptic Techniques & Infection Control Questions and Answers

Question 1

What is the primary purpose of aseptic technique in ophthalmic surgery?

Accepted Answer

To prevent microbial contamination and infection.

Answer

Aseptic technique is a critical set of practices and procedures used in ophthalmic surgery to maintain a sterile environment and prevent the introduction of microorganisms into the surgical site. Its primary purpose is to minimize the risk of surgical site infections, which can have severe consequences for the patient's vision and overall health. By meticulously following aseptic principles, surgical teams ensure patient safety and optimize surgical outcomes.

Question 2

Which of the following is a key component of surgical hand scrubbing?

Accepted Answer

Scrubbing hands and forearms for a sufficient time.

Answer

A key component of surgical hand scrubbing is the thorough and timed washing of hands and forearms using an antimicrobial soap or solution. This process, typically lasting several minutes, is designed to significantly reduce the number of transient and resident microorganisms on the skin. Proper scrubbing technique ensures maximum cleanliness before donning sterile gloves, thereby minimizing the risk of infection during surgery.

Question 3

Which sterilization method is most commonly used for ophthalmic surgical instruments?

Accepted Answer

Autoclaving with steam under pressure.

Answer

Autoclaving, which uses steam under high pressure and temperature, is the most common and effective method for sterilizing heat-stable ophthalmic surgical instruments. This process ensures the complete destruction of all microorganisms, including bacteria, viruses, fungi, and spores. Its reliability and efficiency make it the preferred choice for preparing instruments for sterile surgical procedures.

Question 4

What is the main reason for using sterile drapes during ophthalmic surgery?

Accepted Answer

To maintain a sterile surgical environment.

Answer

Sterile drapes are essential in ophthalmic surgery to establish and maintain a sterile field around the patient and the surgical site. They act as a barrier, preventing microorganisms from non-sterile areas (like the patient's skin or operating room furniture) from contaminating the surgical incision and instruments. This significantly reduces the risk of post-operative infections, which is paramount for patient safety.

Question 5

Which precaution is critical when handling ophthalmic surgical instruments?

Accepted Answer

Ensuring they remain in a sterile field at all times.

Answer

A critical precaution when handling ophthalmic surgical instruments is to ensure they remain within the sterile field from the moment they are sterilized until they are used. Any contact with non-sterile surfaces or personnel can contaminate the instrument, rendering it unsafe for use and increasing the risk of infection. Maintaining sterility is fundamental to preventing surgical site infections and ensuring patient safety.
