Question 1

Which laryngoscope blade design provides a straight path to lift the epiglottis directly?

Accepted Answer

Miller blade

Answer

The Miller blade is a straight blade designed to directly lift the epiglottis to expose the glottis.

Question 2

What is the primary function of the adjustable pressure-limiting (APL) valve in an anesthesia breathing circuit?

Accepted Answer

Vent excess gas to the scavenging system

Answer

The APL valve opens to release excess gas from the circuit into the waste gas scavenging system, controlling circuit pressure.

Question 3

A cuffed endotracheal tube cuff pressure should be maintained below which value to prevent tracheal mucosal ischemia?

Accepted Answer

30 cmH2O

Answer

Cuff pressures above 30 cmH2O exceed tracheal mucosal capillary perfusion pressure and risk ischemic injury.

Question 4

Which size supraglottic airway device (LMA Classic) is recommended for an adult patient weighing 70 kg?

Accepted Answer

Size 4

Answer

LMA Classic size 4 is recommended for adults weighing 50–70 kg, making it appropriate for a 70 kg patient.

Question 5

The Mallampati classification is used to predict difficulty with which aspect of airway management?

Accepted Answer

Laryngoscopy and intubation

Answer

Mallampati scoring assesses oropharyngeal visibility to predict the likelihood of difficult direct laryngoscopy and intubation.
