Question 1

Which oxygen delivery device provides the HIGHEST reliable inspired oxygen concentration for a spontaneously breathing patient experiencing desaturation during conscious sedation?

Accepted Answer

Non-rebreather mask at 15 L/min

Answer

A non-rebreather mask with a reservoir bag at 15 L/min delivers 90–95% FiO2, the highest concentration achievable without positive pressure in a spontaneously breathing patient.

Question 2

What is the correct technique for verifying IV patency before administering sedation medications?

Accepted Answer

Aspirate for blood return and flush with normal saline, observing for swelling or resistance

Answer

Aspirating for blood return and flushing while observing for infiltration confirms IV patency and prevents extravasation of sedation drugs.

Question 3

During conscious sedation, the pulse oximeter probe on the patient's finger shows a low signal quality alert. What should the nurse do FIRST?

Accepted Answer

Reposition or replace the probe to restore reliable signal before continuing

Answer

A low-quality SpO2 signal is unreliable; repositioning or replacing the probe ensures continuous valid oxygenation monitoring required during sedation.

Question 4

Which piece of emergency equipment must be physically present and operational in the room during every conscious sedation procedure?

Accepted Answer

Intubation tray with laryngoscope and endotracheal tubes

Answer

An intubation tray with a functional laryngoscope and appropriately sized ETT must be immediately available in case the patient requires airway rescue during sedation.

Question 5

What is the primary advantage of using a nasal cannula with capnography sampling port during conscious sedation?

Accepted Answer

It simultaneously provides supplemental oxygen AND monitors exhaled CO2

Answer

Combination nasal cannulae with ETCO2 sampling allow continuous capnography without interrupting supplemental oxygen delivery.
