DAANCE Levels of Sedation 2

Question 1

According to the ASA continuum, which level of sedation is characterized by loss of consciousness with inability to be aroused even by painful stimulation?

Accepted Answer

General anesthesia

Answer

General anesthesia is defined by unarousability, loss of protective airway reflexes, and requirement for airway support.

Question 2

A patient under moderate sedation (conscious sedation) should be able to:

Accepted Answer

Maintain spontaneous ventilation and respond purposefully to verbal commands

Answer

The defining features of moderate sedation are purposeful response to verbal or light tactile stimulation and maintenance of spontaneous ventilation.

Question 3

Which factor most commonly causes unintended deepening of sedation beyond the intended level?

Accepted Answer

Synergistic drug interactions when combining opioids and benzodiazepines

Answer

Combining opioids and benzodiazepines produces synergistic CNS and respiratory depression, significantly increasing the risk of deeper-than-intended sedation.

Question 4

The purpose of pre-sedation fasting (NPO) guidelines before IV sedation is to:

Accepted Answer

Reduce gastric volume and acidity, lowering aspiration risk during sedation

Answer

NPO guidelines reduce the risk of pulmonary aspiration by lowering gastric volume. The ASA recommends fasting from solids for 6 hours and clear liquids for 2 hours before sedation.

Question 5

During moderate IV sedation, which monitoring parameter is MANDATORY throughout the procedure?

Accepted Answer

Continuous pulse oximetry and blood pressure at regular intervals

Answer

Continuous pulse oximetry and regular blood pressure monitoring are the minimum mandatory requirements for moderate sedation.
