CAA Perioperative Care & Patient Monitoring

Question 1

According to ASA basic monitoring standards, which of the following must be continuously monitored via capnography during general anesthesia with an endotracheal tube?

Accepted Answer

End-tidal CO2 (ETCO2)

Answer

Urine output

Answer

Central venous pressure

Answer

Serum electrolytes

Question 2

What is the normal range for end-tidal CO2 (ETCO2) during controlled mechanical ventilation in a healthy patient?

Accepted Answer

35–45 mmHg

Answer

10–20 mmHg

Answer

20–30 mmHg

Answer

50–60 mmHg

Question 3

A sudden decrease in ETCO2 to near zero during mechanical ventilation most likely indicates:

Breathing circuit disconnection or cardiac arrest

Answer

Hypoventilation

Answer

Metabolic alkalosis

Answer

Increased CO2 production from fever

Accepted Answer

Preoperative phase

Answer

Intraoperative phase

Answer

Postoperative phase

Answer

Recovery room phase

0.5 mL/kg/hr

Answer

0.1 mL/kg/hr

Answer

2.0 mL/kg/hr

Answer

5.0 mL/kg/hr
