Question 1

Which monitoring modality provides a continuous waveform that is considered the GOLD STANDARD for confirming endotracheal tube placement in the airway?

Accepted Answer

End-tidal CO2 capnography

Answer

Continuous capnography showing a persistent CO2 waveform is the gold standard for confirming correct endotracheal intubation, as it detects esophageal intubation immediately.

Question 2

A train-of-four (TOF) ratio of 0.9 or greater indicates:

Accepted Answer

Adequate recovery of neuromuscular function for extubation

Answer

A TOF ratio ≥0.9 indicates adequate recovery of neuromuscular function and is a criterion for safe extubation without risk of residual paralysis.

Question 3

The bispectral index (BIS) monitor measures what parameter to guide anesthetic depth?

Accepted Answer

Processed EEG activity correlating with level of consciousness

Answer

BIS analyzes the processed EEG to produce a dimensionless number (0–100) correlating with depth of anesthesia; values of 40–60 indicate general anesthesia.

Question 4

ST-segment analysis on an intraoperative ECG monitor is most useful for detecting:

Accepted Answer

Myocardial ischemia

Answer

ST-segment elevation or depression on continuous ECG monitoring is the primary intraoperative indicator of myocardial ischemia or injury.

Question 5

Which noninvasive blood pressure (NIBP) cuff size error would cause a falsely HIGH reading?

Accepted Answer

Cuff too narrow for the arm

Answer

A cuff that is too narrow relative to arm circumference overestimates blood pressure because higher pressure is needed to occlude arterial flow.
