2025 | Guaranteed Pass
Smaller tissue area, greater current density and faster heating - Answer✔e.g. Bovie tip
Cut mode - Answer✔- Low voltage
- High frequency
- Continuous waveform
- Heats tissue quickly; cell water converts to steam and causes cell to explode
Coagulation mode - Answer✔- High voltage
- Low frequency
- Intermittent waveform
- Rapid tissue heating, shallow depth of necrosis
- Non-contact: relies on sparking to tissue
Capacitive coupling - Answer✔Transfer current from active electrode through insulation to
passive electrode- electrode to plastic part another LSC instrument
- if constant contact w/ tissue will not store energy and no injury
Direct coupling - Answer✔monopolar instrument in direct contact w/ metal portion of another
instrument

Besides capacitative coupling and direct coupling, other hazards of electrocautery - Answer✔-
Current diversion
- Narrow return circuit
Bipolar - Answer✔- forceps w/ two twins (one active other return)
- no pt return electrode required)
- no capacitative coupling
- works in "wet" operative field
- less thermal spread compared to monopolar
bipolar seals vessels up to _____ mm in diameter - Answer✔7 mm
ultrasonic coagulation shears seals vessels up to ____ mm in diameter - Answer✔5 mm
ultrasonic coagulation shears - Answer✔- combo compression and friction
- ONE active blade
- monopolar capacity w/ the one blade
- no capacitative coupling
- high power (MAX): cut
- low power (MIN): coag
warfarin is to be discontinued ____ days prior to surgery - Answer✔3 days
mild to moderate systemic disease - Answer✔ASA 2
severe systemic disease that limits patient activity, may or may not be related to reason for
surgery - Answer✔ASA 3
