Chapter 9: Surgical Pharmacology and Anesthesia

Which sensory input is the last one to be suppressed by the anesthetic agent(s) during the induction phase of general anesthesia?

• Sight
• Touch
• Hearing
• Smell

During the induction phase, the Certified Surgical Technologist (CST) should halt preparatory activities to avoid making noise because:

• the anesthesia provider requires silence to concentrate on intubation.
• the surgical prep solution contains volatile agents that need time to dissipate.
• the patient's hearing is the last sense to be suppressed and may become more acute.
• the patient is already in Stage III (Surgical Anesthesia) and should be undisturbed.

The surgical intervention takes place entirely during which phase of general anesthesia?

• Induction Phase
• Preinduction Period
• Maintenance Phase
• Emergence Phase

During the Maintenance Phase of general anesthesia, the anesthesia provider must be prepared to adjust anesthetic levels in response to rapid changes caused by:

• the return of the gag reflex.
• patient rigidity and tremors.
• surgical manipulation.
• aspiration of gastric contents.

The goal of the emergence phase is to have the patient as awake as possible, with a primary focus on monitoring the independent respiratory rate and the restoration of what reflex?

• The swallowing reflex
• The blink reflex
• The gag reflex
• The coughing reflex

The period when the surgical intervention is concluding and the patient is beginning to awaken, often experiencing risks like laryngospasm and muscle tremors, is known as the:

• Induction Phase
• Maintenance Phase
• Emergence Phase
• Recovery Phase

The recovery phase of general anesthesia usually begins in which location?

• The Postanesthesia Care Unit (PACU)
• The Preoperative Holding Area
• The OR suite
• The Intensive Care Unit (ICU)

Which statement accurately describes the conclusion of the recovery phase of general anesthesia?

• It is completed when the patient reaches Stage III (Surgical Anesthesia).
• It ends when the patient is discharged and completes the initial healing stages.
• It continues indefinitely until all anesthetic agents are biotransformed by the liver.
• It is complete once the patient is extubated in the OR suite.

Which noninvasive monitoring device is placed on the patient's forehead to continuously monitor brain waves and compute a number reflecting the level of anesthesia or consciousness?

• Pulse Oximeter
• Central Venous Pressure Catheter
• Bispectral Index (BIS) Monitor
• Pulmonary Artery Catheter

This device assesses the level of neuromuscular blockade by electrically stimulating a peripheral nerve, such as the ulnar nerve, to cause muscle contractions.

• Spirometry Monitor
• Peripheral Nerve Stimulator
• Oxygen Analyzer
• Electrocardiogram (ECG)
