Actual Qs and Ans - Expert-Verified Explanation -Guaranteed passing score -21 Questions and Answers
-Format: Multiple-choice / Flashcard
Question 1: when does dissection occur? temp above 600 degrees
Answer:
postoperative nausea/vomiting risk factors
Question 2: what is monopolar used for?
Answer:
small vessels slow rate of bleeding need a dry operative field
Question 3: absolute contraindications to laparoscopy
Answer:
- unable to tolerate laparotomy
- hypovolemic shock
- lack of surgeon training
- no support @ hospital
Question 4: lower energy, producing less lateral tissue damage and necrosis
- DONT need a grounding pad
Answer:
risks of bipolar energy
Question 5: no
Answer:
how to enter in patient with bowel obsturction Question 6: rapid surface heating with shallow depth of necrosis, intermittent wave form with higher voltage
Answer:
risks of monopolar Question 7: female, young, previous issues, morning sickness, nonsmoker, procedural length, lower ASA classification, preoperative anxiety, prevention involves using anti emetics, limiting opioids if possible
Answer:
what is the most commonly used light source?
Question 8: nitric oxide
Answer:
less acid base issues, can be tolerated in cardiopulmonary patients, slightly less postoperative pain
Question 9: visceral artery aneurysm
Answer:
risk of injury w/ trocar insertion previous abdominal surgery scars can be an issue, may have intraperitoneal adhesions
Question 10: 300 W xenon lamp
Answer:
what if there is initial low pressure and high flow rate at entry?
Question 11: active blade can injure something due to high frequency (50 MHz)
Answer:
do you discontinue aspirin the day of surgery?
Question 12: CO2
Answer:
readily absorbed, easily eliminated increase end tidal CO2, increase arterial CO2 concentration, decrease serum pH, greatest change is seen in the first 20 minutes
Question 13: what is bipolar rused for?
Answer:
larger vessels need a wet operative field less lateral thermal spread
- not good for capillary vessels
Question 14: which has less light - 5 mm 30 degree lens or 10 mm 0 degree?
Answer:
- mm 30 degree
Question 15: relative contraindications to laparoscopy
Answer:
- can't tolerate general anesthesia
- long standing peritonitis
- large abdominal/pelvic mass
- massive hernia
- severe cardiopulmonary disease
Question 16: risk of cutting patient vessels before adequate sealing, device doesn't work if metal between the jars
Answer:
risks of ultrasonic dissection (harmonic) Question 17: capacitative coupling - transfer of energy between two conductors separated by insulator, transfer to passive electrode. can release with tissue injury but no issue if ground plate working as capacitor - can't store the charge
Answer:
benefits of bipolar energy
Question 18: most common sources of unrecognized bleeding
Answer:
trocar injury of abdominal vessels,
Question 19: gas embolus
Answer:
rare but can occur seen less than 1 percent of the time diagnose with severe hypotension, JVD, tachycardia, mill wheel murmur
- need to rule out other sources of hypotension
Question 20: leak in insufflator circuit, make sure everything is plugged in correctly
Answer:
what does coagulation mode do?Question 21: current can be diverted through unintentional pathways, leading to inadvertent tissue injury
- don't use hybrid ports that mix metal with plastic
Answer:
why do you need a grounding pad for monopolar?
