CET CET Emergency Response & Patient Safety 2

Question 1

The pre-procedure 'time-out' in endoscopy is performed to:

Accepted Answer

Verify patient identity, correct procedure, and relevant clinical information

Answer

The pre-procedure time-out is a Joint Commission-mandated safety protocol to confirm correct patient, correct procedure, and relevant allergies or contraindications before starting.

Question 2

Which patient position is standard for upper endoscopy (EGD)?

Accepted Answer

Left lateral decubitus

Answer

Left lateral decubitus (left side down) is the standard position for EGD because it reduces aspiration risk and facilitates passage of the scope through the esophagus.

Question 3

What does capnography monitoring assess during endoscopy sedation?

Accepted Answer

End-tidal CO2 to evaluate ventilation adequacy

Answer

Capnography measures end-tidal CO2 (ETCO2), providing real-time assessment of ventilation and detecting respiratory depression before oxygen desaturation occurs.

Question 4

If a sedated endoscopy patient's SpO2 drops to 88%, the FIRST intervention is:

Accepted Answer

Apply supplemental oxygen and provide jaw-thrust stimulation

Answer

Supplemental oxygen and stimulation (jaw-thrust, sternal rub) are the first-line responses to mild desaturation and often reverse the problem without requiring reversal agents.

Question 5

Which action is UNSAFE during post-endoscopy recovery and should be avoided?

Accepted Answer

Allowing the patient to walk immediately after receiving sedation

Answer

Allowing immediate ambulation before adequate recovery from sedation increases the risk of falls and injury; patients must meet discharge criteria first.
