FANZCA FANZCA Perioperative Care and Management 2

Question 1

What is the Mallampati classification system used for in anesthetic preoperative assessment?

Accepted Answer

Predicting the ease of tracheal intubation based on oropharyngeal visibility

Answer

Assessing the degree of hepatic dysfunction before surgery

Answer

Classifying the severity of cardiac disease for risk stratification

Answer

Grading the extent of surgical field for regional anesthesia planning

Question 2

In perioperative anesthetic management, which strategy is recommended for patients at high risk of postoperative nausea and vomiting (PONV)?

Accepted Answer

Multimodal prophylaxis including TIVA with propofol, ondansetron, and dexamethasone

Answer

Inhalational anesthesia with high-dose opioids

Answer

Restriction of IV fluids to reduce gastric distension

Answer

Routine nasogastric tube placement postoperatively

Question 3

What does a bispectral index (BIS) value of 40–60 indicate during general anesthesia?

Accepted Answer

An adequate level of hypnosis with low risk of awareness

Answer

The patient is awake and alert

Answer

The patient is in burst suppression with potential for oversedation

Answer

The patient requires more neuromuscular blockade

Question 4

Which parameter most reliably indicates return of adequate neuromuscular function before tracheal extubation using quantitative monitoring?

Accepted Answer

Train-of-four ratio (TOF ratio) ≥ 0.9

Answer

Ability to sustain a 5-second head lift

Answer

Return of spontaneous breathing

Answer

Visual confirmation of four twitches on train-of-four stimulation

Question 5

In perioperative cardiac risk assessment, what does the Revised Cardiac Risk Index (RCRI) estimate?

Accepted Answer

Risk of major adverse cardiac events (MACE) after noncardiac surgery

Answer

Intraoperative blood loss requiring transfusion

Answer

Likelihood of postoperative respiratory failure requiring reintubation

Answer

Preoperative cardiac medication adjustment requirements

Question 6

What is the significance of measuring lactate levels perioperatively in critically ill or high-risk surgical patients?

Accepted Answer

Elevated lactate indicates tissue hypoperfusion and anaerobic metabolism, guiding resuscitation targets

Answer

It directly measures oxygen delivery to individual organs

Answer

Lactate is a measure of hepatic synthetic function during surgery

Answer

It is used exclusively to titrate vasopressor infusions
