Question 2

The perioperative nurse notes a patient's SpO2 is 94% on room air pre-operatively. What is the most appropriate initial action?

Question 3

What does the term 'balanced anesthesia' refer to?

Balanced anesthesia uses a combination of drugs—each targeting a specific component—to minimize side effects while achieving all desired anesthetic effects.

Question 4
