CSC CSC Sedation Equipment & Technology 1 — Questions and Answers
Question 1: What is the purpose of a bite block during procedures performed under conscious sedation?
- To maintain airway patency by lifting the jaw
- To prevent the patient from biting equipment or injuring oral structures (Correct answer)
- To deliver supplemental oxygen
- To measure end-tidal CO2
Correct answer: To prevent the patient from biting equipment or injuring oral structures
A bite block protects endoscopes, airways, and the patient's teeth and soft tissues from bite injury during sedation procedures.
Question 2: Which device provides CONTINUOUS, non-invasive monitoring of ventilation during conscious sedation and is more sensitive than pulse oximetry for detecting apnea?
- Precordial stethoscope
- Capnography (ETCO2) monitor (Correct answer)
- Transcutaneous oxygen monitor
- Impedance pneumography
Correct answer: Capnography (ETCO2) monitor
Capnography measures exhaled CO2 breath by breath, detecting apnea immediately, whereas pulse oximetry lags by 30–60 seconds due to oxygen reserves.
Question 3: A three-lead ECG monitor during conscious sedation is MOST useful for detecting which complication?
- Respiratory depression
- Hypoglycemia
- Dysrhythmias caused by sedative medications or hypoxia (Correct answer)
- Anaphylaxis
Correct answer: Dysrhythmias caused by sedative medications or hypoxia
Continuous ECG monitoring allows real-time detection of arrhythmias that may be triggered by sedative agents, hypoxia, or vagal stimulation during the procedure.
Question 4: What minimum suction capability is required at the bedside during conscious sedation?
- Portable bulb syringe only
- Functional wall or portable suction with a large-bore (Yankauer) tip (Correct answer)
- A 60 mL oral syringe
- No suction is required for moderate sedation
Correct answer: Functional wall or portable suction with a large-bore (Yankauer) tip
Functional suction with a large-bore tip must be immediately available to clear secretions or vomitus and prevent aspiration during sedation.
Question 5: What does a NIBP cuff error reading during conscious sedation require the nurse to do?
- Continue the procedure and reassess in 15 minutes
- Troubleshoot and restore NIBP monitoring before continuing sedation (Correct answer)
- Switch to SpO2 as a blood pressure surrogate
- Document the error and proceed
Correct answer: Troubleshoot and restore NIBP monitoring before continuing sedation
Blood pressure monitoring is mandatory during conscious sedation; a non-functional NIBP requires immediate troubleshooting because hemodynamic instability must be detected.
Question 6: Which IV access requirement is standard prior to initiating conscious sedation?
- A central venous catheter must be placed
- A patent peripheral IV must be in place before sedation begins (Correct answer)
- IV access is optional if the patient is low-risk
- A peripherally inserted central catheter (PICC) is preferred
Correct answer: A patent peripheral IV must be in place before sedation begins
A functioning peripheral IV line must be established before sedation to allow emergency drug administration if complications arise.
