CSC CSC Procedural Sedation Techniques & Equipment 2 — Questions and Answers
Question 1: Which monitoring device provides continuous, non-invasive assessment of respiratory function by measuring exhaled carbon dioxide?
- Pulse oximetry
- Capnography (Correct answer)
- Impedance pneumography
- Peak flow meter
Correct answer: Capnography
Capnography measures end-tidal CO2 and provides an early warning of respiratory depression before oxygen saturation falls on pulse oximetry.
Question 2: What is the recommended supplemental oxygen delivery method for most patients receiving moderate sedation?
- Non-rebreather mask at 15 L/min
- Nasal cannula at 2–4 L/min (Correct answer)
- Simple face mask at 10 L/min
- Venturi mask at 28%
Correct answer: Nasal cannula at 2–4 L/min
A nasal cannula at 2–4 L/min is the standard supplemental oxygen method during moderate sedation as it is comfortable and does not interfere with capnography sampling.
Question 3: During a moderate sedation procedure, how frequently should the patient's vital signs be documented at a minimum?
- Every 15 minutes
- Every 5 minutes (Correct answer)
- Every 30 minutes
- Only at the start and end
Correct answer: Every 5 minutes
Vital signs including SpO2, respiratory rate, blood pressure, heart rate, and level of consciousness should be documented at least every 5 minutes during moderate sedation.
Question 4: What does a Ramsay Sedation Scale score of 4 indicate?
- Patient is anxious and agitated
- Patient is asleep with brisk response to light stimulation (Correct answer)
- Patient is asleep with sluggish response
- Patient is fully awake and cooperative
Correct answer: Patient is asleep with brisk response to light stimulation
A Ramsay score of 4 indicates a patient who is asleep but responds briskly to a light glabellar tap or loud auditory stimulus.
Question 5: Which of the following is the correct position for a patient experiencing nausea or vomiting during sedation?
- Supine with legs elevated
- Semi-Fowler's position
- Lateral recovery (rescue) position (Correct answer)
- Trendelenburg position
Correct answer: Lateral recovery (rescue) position
The lateral recovery position protects the airway by allowing secretions and vomitus to drain away from the trachea, reducing aspiration risk.
Question 6: Which intravenous access site is preferred for administering sedation medications to allow rapid absorption and avoid extravasation risk?
- Peripheral IV in the hand
- Central venous catheter
- Peripheral IV in the antecubital fossa (Correct answer)
- Intraosseous access
Correct answer: Peripheral IV in the antecubital fossa
A peripheral IV in the antecubital fossa is preferred because it is large-bore, less prone to infiltration, and provides rapid medication delivery.
