DAANCE Post-Anesthesia Care and Recovery Management 4 — Questions and Answers
Question 1: A patient in the recovery phase following IV sedation reports feeling dizzy and nauseated when attempting to sit upright. Which intervention should be performed first?
- Administer ondansetron IV
- Return the patient to a supine position and reassess (Correct answer)
- Offer oral fluids and crackers
- Discharge the patient with antiemetic prescription
Correct answer: Return the patient to a supine position and reassess
Returning the patient to supine relieves orthostatic hypotension and reduces nausea before further interventions are considered.
Question 2: Which Aldrete score total indicates a patient is ready for discharge from the immediate post-anesthesia recovery area?
- 6 or above
- 7 or above
- 8 or above (Correct answer)
- 10 only
Correct answer: 8 or above
A modified Aldrete score of 8 or above (out of 10) is the standard threshold for discharge readiness from the post-anesthesia recovery area.
Question 3: A patient recovering from deep sedation has an SpO2 of 91% on room air. The MOST appropriate immediate action is to:
- Document and monitor for 5 minutes
- Apply supplemental oxygen via nasal cannula (Correct answer)
- Prepare for endotracheal intubation
- Administer flumazenil
Correct answer: Apply supplemental oxygen via nasal cannula
Supplemental oxygen via nasal cannula is the first-line response to mild post-sedation hypoxemia before escalating to advanced airway management.
Question 4: Which of the following is the PRIMARY reason a responsible adult escort is required for a patient who received moderate sedation?
- To witness the discharge instructions
- Because residual sedative effects impair judgment and motor function (Correct answer)
- To ensure payment is completed
- To administer oral medications at home
Correct answer: Because residual sedative effects impair judgment and motor function
Residual benzodiazepine and opioid effects can impair cognition and coordination, making independent transportation unsafe.
Question 5: A post-sedation patient's blood pressure is 158/96 mmHg, up from a pre-operative baseline of 122/78 mmHg. This elevation is MOST likely caused by:
- Overhydration from IV fluids
- Emergence agitation and pain (Correct answer)
- Hypoglycemia
- Residual vasopressor effect
Correct answer: Emergence agitation and pain
Emergence agitation and uncontrolled pain are the most common causes of transient post-sedation hypertension in the dental office setting.
Question 6: When assessing a patient's level of consciousness during post-anesthesia recovery, the dental team should evaluate all of the following EXCEPT:
- Orientation to person, place, and time
- Ability to follow simple commands
- Capillary refill time (Correct answer)
- Purposeful response to verbal stimulation
Correct answer: Capillary refill time
Capillary refill time is a perfusion/circulatory assessment, not a component of neurological consciousness evaluation.
Question 7: A patient who received midazolam and fentanyl for sedation develops respiratory depression in recovery. After providing supplemental oxygen and repositioning the airway, which reversal agent should be considered FIRST?
- Flumazenil, because midazolam is the primary sedative
- Naloxone, because fentanyl-induced respiratory depression is more common (Correct answer)
- Sugammadex, to reverse neuromuscular blockade
- Epinephrine, for anaphylaxis management
Correct answer: Naloxone, because fentanyl-induced respiratory depression is more common
Opioid-induced respiratory depression typically presents more acutely than benzodiazepine-induced depression, making naloxone the preferred first reversal agent.
