Free FLS Instrumentation and Physiologic Principles Questions and Answers

Question 1

During monopolar cautery, which method involves quickly turning cell water to steam, causing the cell to explode?

Accepted Answer

Cutting

Answer

Explanation:
During monopolar cautery, the cutting mode uses high-frequency electrical current to rapidly vaporize tissue, turning cell water into steam and causing the cell to explode. This process allows for precise tissue cutting during surgery.

Question 2

What does ASA class 3 indicate?

Accepted Answer

Severe systemic disease that limits the patient's activity and may or may not be related to the reason for surgery

Answer

Explanation:
ASA class 3 denotes a patient with severe systemic disease that limits their activity, and this condition may or may not be related to the reason for surgery. It indicates significant health concerns that may impact the patient's perioperative care and overall outcome.

Question 3

The use of all-plastic or all-metal trocars can avoid which problem?

Accepted Answer

Capacitative coupling

Answer

Explanation:
All-plastic or all-metal trocars eliminate the risk of capacitative coupling, which can occur when a metal trocar comes into contact with an insulated electrosurgical instrument, leading to unintended energy transfer and tissue injury. Using trocars made of non-conductive materials prevents this problem.

Question 4

What should you do with the harmonic scalpel to avoid inadvertent injury?

Accepted Answer

All of the above

Answer

Explanation:
To avoid inadvertent injury with the harmonic scalpel, it's important to be aware of the blade, grab and elevate your target, and keep the active blade upwards and in view to prevent unintended tissue damage. These precautions help ensure safe and effective use of the harmonic scalpel during laparoscopic surgery.

Question 5

Which statement is NOT true about general anesthesia in laparoscopic surgery?

Accepted Answer

Fewer hemodynamic changes compared to local anesthesia

Answer

Explanation:
General anesthesia typically induces significant hemodynamic changes, including alterations in blood pressure and heart rate, whereas local anesthesia generally produces fewer systemic effects.
