FLS EXAM QUESTIONS
Actual Qs and Ans - Expert-Verified Explanation -Guaranteed passing score -100 Questions and Answers
-Format: Multiple-choice / Flashcard
Question 1: ASA 3
Answer:
severe systemic disease that limits patient activity, may or may not be related to reason for surgery
Question 2: Days until full diet tolerated
Answer:
1-2d for fundoplication 3-6d for colon resection
Question 3: 4-4.5 mm staples
Answer:
- green
- for distal stomach, thickened portions of GI tract
Question 4: Why do you need a grounding pad for monopolar?
Answer:
Capacitative coupling - transfer of energy between two conductors separated by an insulator, transfer to passive electrode. Can release with tissue injury, but no issue if ground plate is working as capacitor can't store the charge
Question 5: Gas embolism diagnosis
Answer:
Severe hypotension, JVD, tachycardia, Mill wheel murmur (characteristic)
[R/o other source of hypotension: bleeding, pneumothorax, 1ry cardiac failure)
Question 6: What is the incidence of VTE following laparoscopic colocystectomy?
Answer:
0.5%
Question 7: FNA uses ______G needle
Answer:
20-22 G
Question 8: Length of trocar needed for obese pt
Answer:
>100 mm
Question 9: How to enter in patient with bowel obstruction?
Answer:
Direct visualization
Question 10: Renal effects of pneumoperitoneum
Answer:
Intraoperative oliguria (increased intraabdominal pressure --> decreases renal blood flow --> decrease filtration and urine output --> 2ry release of renin and ADH --> sodium and free water reabsorption --> oliguria) Postoperative oliguria usually resolves within a couple hours
Question 11: Chemical effects of CO2
Answer:
- Increase arterial and end tidal CO2
- Decrease serum pH w/ greatest change in first 20 min (SS after 1h)
Question 12: Monopolar voltage/frequency
Answer:
Low voltage/High frequency
Question 13: bipolar seals vessels up to _____ mm in diameter
Answer:
- mm
Question 14: 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
Question 15: which of these is NOT an absolute contraindication to laparoscopic surgery?
Answer:
bowel obstruction (contraindications include uncorrectable hypovolemic shock, lack of proper surgical training, and inability to tolerate laparotomy)
Question 16: When should a check for venous bleeding be performed?
Answer:
during final abdominal inspection, while releasing abdominal pressure, and during trocar removal
Question 17: ASA class 3
Answer:
severe systemic disease that limits the patient's activity and may or may not be related to the reason for surgery
Question 18: 2-2.5 mm staples used for
Answer:
- white/grey in color
- vascular, thinner tissue
Question 19: ultrasonic coagulation shears seals vessels up to ____ mm in diameter
Answer:
- mm
Question 20: Direct coupling
Answer:
monopolar instrument in direct contact w/ metal portion of another instrument Question 21: the use of all plastic or all metal trocars can avoid which problem during electrosurgery?
Answer:
capacitative coupling is a result of using a metal tracer with a plastic screw anchor, which prevents the tracer from draining its charge (instrument can store the charge and then transmit to tissue next time it touches something)
Question 22: Pulmonary physiology with pneumoperitoneum
Answer:
Increase minute ventilation to eliminate absorbed CO2 Reduced functional residual capacity (FRC) Increase peak airway pressure Reduced pulmonary compliance Reduced diaphragmatic excursion Question 23: click on the point that is in danger of thermal burn if a monopolar electrode is applied to the end of the appendiceal stump?
Answer:
the diameter at the ligature is half that at the stump, so the current density will be 16X greater
Question 24: Discontinue aspirin day of surgery?
Answer:
No
Question 25: Cardiovascular changes with pneumoperitoneum
Answer:
Increased preload and afterload Decreased cardiac output --> hypotension, cardiac arrhythmia, decreased urine output, increased end tidal CO2 (signs and symptoms of reduced tissue perfusion)
