SGNA Sedation and Analgesia 1 — Questions and Answers
Question 1: According to SGNA standards, which level of sedation involves a drug-induced state where patients respond purposefully to verbal or tactile stimulation?
- Moderate sedation/analgesia (Correct answer)
- Minimal sedation
- Deep sedation
- General anesthesia
Correct answer: Moderate sedation/analgesia
Moderate sedation (conscious sedation) is defined by purposeful response to verbal or tactile stimulation with maintained airway reflexes, the most common level used in GI endoscopy.
Question 2: What is the reversal agent for benzodiazepine overdose during procedural sedation?
- Flumazenil (Correct answer)
- Naloxone
- Neostigmine
- Atropine
Correct answer: Flumazenil
Flumazenil competitively antagonizes GABA-A benzodiazepine receptors and reverses benzodiazepine-induced sedation and respiratory depression.
Question 3: Which ASA physical status classification describes a patient with severe systemic disease that is a constant threat to life?
- ASA IV (Correct answer)
- ASA III
- ASA II
- ASA V
Correct answer: ASA IV
ASA IV indicates severe systemic disease that is a constant threat to life, requiring heightened monitoring and risk assessment before sedation.
Question 4: During moderate sedation, which parameter should be monitored continuously according to SGNA guidelines?
- Oxygen saturation (SpO2) (Correct answer)
- Blood pressure only
- End-tidal CO2 only
- Pupillary response
Correct answer: Oxygen saturation (SpO2)
Continuous pulse oximetry monitoring of oxygen saturation is mandatory during moderate sedation to detect early hypoxemia before clinical signs appear.
Question 5: What is the recommended fasting time for clear liquids before elective endoscopy with sedation in adult patients?
- 2 hours (Correct answer)
- 4 hours
- 6 hours
- 8 hours
Correct answer: 2 hours
Current ASA and SGNA guidelines recommend a minimum 2-hour fast from clear liquids before elective procedures with sedation in healthy adults.
Question 6: Naloxone is the reversal agent for which class of medications used in procedural sedation?
- Opioids (Correct answer)
- Benzodiazepines
- Propofol
- Anticholinergics
Correct answer: Opioids
Naloxone is a competitive opioid receptor antagonist that reverses opioid-induced respiratory depression, sedation, and analgesia.
