Question 2

When performing a pre-anesthetic physical exam, which ASA classification applies to a patient with a severe systemic disease that is a constant threat to life?

Accepted Answer

ASA IV

Answer

ASA IV describes a patient with severe systemic disease that is a constant life threat, representing very high anesthetic risk.

Question 3

Which of the following inhalant anesthetics has the LOWEST blood:gas partition coefficient, resulting in the fastest induction and recovery?

Accepted Answer

Desflurane

Answer

Desflurane has the lowest blood:gas partition coefficient (0.42), meaning it equilibrates rapidly and produces the fastest induction and recovery.

Question 4

A technician notices that the CO2 absorbent granules in a circle system have turned permanently blue-purple throughout. What does this indicate?

Accepted Answer

The absorbent is exhausted and must be replaced

Answer

Most CO2 absorbents contain a pH indicator that permanently changes color (e.g., blue-purple for Baralyme, violet for Sodasorb) when exhausted and unable to absorb CO2.

Question 5

Which opioid is considered a full mu-receptor agonist and is commonly used intraoperatively as a constant rate infusion (CRI) for analgesia?

Answer

Fentanyl is a potent full mu-agonist with rapid onset and short duration, making it ideal for intraoperative CRI analgesia.
