CSC Patient Assessment & Monitoring 3 — Questions and Answers
Question 1: Which of the following best describes a modified Ramsey Sedation Scale score of 4?
- Patient is anxious and agitated
- Patient is cooperative, oriented, and calm
- Patient is asleep with brisk response to stimulation
- Patient is asleep with sluggish response to stimulation (Correct answer)
Correct answer: Patient is asleep with sluggish response to stimulation
A Ramsey score of 4 means the patient is asleep and responds sluggishly to a light glabellar tap or loud auditory stimulus.
Question 2: A 72-year-old patient undergoing colonoscopy with conscious sedation has a resting heart rate of 48 bpm and is asymptomatic. Which medication history finding would BEST explain this?
- Daily aspirin use
- Chronic beta-blocker therapy (Correct answer)
- Long-term proton pump inhibitor use
- Statin medication use
Correct answer: Chronic beta-blocker therapy
Beta-blockers reduce heart rate and can cause bradycardia, which must be considered when assessing baseline vital signs and planning sedation.
Question 3: What is the minimum recommended NPO time for clear liquids before elective procedures requiring moderate sedation per ASA guidelines?
- 1 hour
- 2 hours (Correct answer)
- 4 hours
- 6 hours
Correct answer: 2 hours
ASA guidelines recommend a minimum 2-hour NPO period for clear liquids before procedures requiring moderate sedation.
Question 4: A patient's bispectral index (BIS) monitor reads 72 during a procedure. This value indicates:
- General anesthesia
- Deep sedation
- Moderate/conscious sedation (Correct answer)
- Minimal sedation or anxiolysis
Correct answer: Moderate/conscious sedation
BIS values of 60–80 correspond to moderate to deep sedation; the target for conscious sedation is typically 70–85.
Question 5: Which patient position is preferred to maintain a patent airway and reduce aspiration risk during conscious sedation?
- Supine with head flat
- Left lateral decubitus (recovery position) (Correct answer)
- Prone
- Steep Trendelenburg
Correct answer: Left lateral decubitus (recovery position)
The left lateral decubitus position uses gravity to keep the airway open and allows secretions or vomitus to drain away from the airway.
Question 6: During patient assessment, a history of obstructive sleep apnea (OSA) is significant for conscious sedation because OSA patients:
- Require higher sedation doses due to tolerance
- Are at increased risk for airway obstruction and desaturation (Correct answer)
- Metabolize opioids faster than the general population
- Have lower baseline heart rates requiring dose adjustment
Correct answer: Are at increased risk for airway obstruction and desaturation
OSA patients have anatomical and physiological vulnerabilities that predispose them to airway collapse and oxygen desaturation under sedation.
Question 7: What is the purpose of assessing a patient's Aldrete score in the post-sedation period?
- Determine the depth of sedation achieved
- Evaluate readiness for discharge from the recovery area (Correct answer)
- Calculate appropriate reversal agent dosing
- Screen for allergic reactions to sedation medications
Correct answer: Evaluate readiness for discharge from the recovery area
The Aldrete score (activity, respiration, circulation, consciousness, oxygen saturation) is used to objectively determine when a patient is safe for discharge from recovery.
