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

The Mallampati score (classes I–IV) assesses visibility of oropharyngeal structures with maximal mouth opening, correlating with difficulty of laryngoscopy and intubation.

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

Multimodal PONV prophylaxis combining TIVA (propofol-based), antiemetics from different classes (5-HT3 antagonists, corticosteroids), and minimizing opioids is recommended for high-risk patients.

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

A BIS value of 40–60 reflects adequate anesthetic depth for surgical stimulation with a low probability of intraoperative awareness, according to manufacturer and clinical guidelines.

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

A quantitative TOF ratio of ≥ 0.9 measured by acceleromyography is the gold standard for confirming adequate neuromuscular recovery before extubation, as clinical tests are unreliable for detecting residual block.

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

The RCRI uses six independent predictors (ischemic heart disease, heart failure, cerebrovascular disease, diabetes on insulin, creatinine >2 mg/dL, high-risk surgery) to estimate perioperative MACE risk.
