FANZCA FANZCA Perioperative Care and Management 1 — Questions and Answers
Question 1: According to FANZCA perioperative guidelines, what is the recommended fasting time for clear fluids prior to elective surgery in healthy adults?
- 6 hours
- 4 hours
- 2 hours (Correct answer)
- 8 hours
Correct answer: 2 hours
Current evidence-based guidelines recommend a minimum of 2 hours fasting for clear fluids before elective procedures to reduce aspiration risk while minimizing patient discomfort.
Question 2: What is the primary goal of Enhanced Recovery After Surgery (ERAS) protocols in the perioperative period?
- Reducing the duration of anesthesia
- Minimizing physiological stress responses to improve recovery and reduce complications (Correct answer)
- Eliminating the need for postoperative analgesia
- Mandating same-day discharge for all surgical patients
Correct answer: Minimizing physiological stress responses to improve recovery and reduce complications
ERAS protocols use evidence-based multimodal strategies to attenuate the surgical stress response, aiming to reduce complications, shorten hospital stay, and speed functional recovery.
Question 3: Which ASA physical status classification applies to a patient with severe systemic disease that is a constant threat to life?
- ASA III
- ASA IV (Correct answer)
- ASA V
- ASA II
Correct answer: ASA IV
ASA IV denotes a patient with severe systemic disease that is a constant threat to life, such as recent MI, ongoing cardiac ischemia, severe valvular dysfunction, or septic shock.
Question 4: What is the principal anesthetic concern with a patient presenting for surgery with an undiagnosed difficult airway?
- Delayed emergence from anesthesia
- Risk of 'cannot intubate, cannot oxygenate' (CICO) situation requiring surgical airway (Correct answer)
- Increased risk of awareness under anesthesia
- Higher requirement for muscle relaxants
Correct answer: Risk of 'cannot intubate, cannot oxygenate' (CICO) situation requiring surgical airway
The most critical airway concern is progressing to a CICO scenario where neither bag-mask ventilation nor tracheal intubation can maintain oxygenation, potentially requiring emergency surgical airway.
Question 5: In the context of perioperative fluid management, what does goal-directed fluid therapy (GDFT) primarily use to guide intravenous fluid administration?
- Central venous pressure alone
- Dynamic hemodynamic parameters such as stroke volume variation and pulse pressure variation (Correct answer)
- Urine output as the sole indicator
- Static filling pressures measured by pulmonary artery catheter
Correct answer: Dynamic hemodynamic parameters such as stroke volume variation and pulse pressure variation
GDFT uses dynamic parameters like stroke volume variation and pulse pressure variation obtained from arterial waveform analysis to optimize fluid responsiveness and cardiac output.
Question 6: Which perioperative event is described as a sudden drop in end-tidal CO2 combined with hypotension and hypoxia, classic for venous air embolism?
- Pulmonary embolism from DVT
- Entrainment of air into an open venous system during surgery (Correct answer)
- Bronchospasm from latex allergy
- Tension pneumothorax from positive-pressure ventilation
Correct answer: Entrainment of air into an open venous system during surgery
Venous air embolism occurs when air enters an open vein and obstructs the right heart and pulmonary vasculature, classically presenting with a sudden fall in ETCO2, 'mill-wheel' murmur, hypotension, and hypoxia.
