CAA Anesthesia Principles and Techniques — Questions and Answers
Question 1: Which type of anesthesia is used for major surgeries requiring complete unconsciousness?
- Regional anesthesia
- General anesthesia (Correct answer)
- Local anesthesia
- Sedation
Correct answer: General anesthesia
General anesthesia induces a reversible loss of consciousness, allowing for major surgical procedures without pain or awareness.
Question 2: What is the primary function of an endotracheal tube during anesthesia?
- To administer IV medications
- To maintain an open airway and provide ventilation (Correct answer)
- To measure oxygen saturation
- To monitor blood pressure
Correct answer: To maintain an open airway and provide ventilation
An endotracheal tube maintains an open airway and facilitates mechanical ventilation in patients under general anesthesia.
Question 3: Which monitoring device is essential during general anesthesia to assess oxygenation?
- Electrocardiogram (ECG)
- Pulse oximeter (Correct answer)
- Capnograph
- Sphygmomanometer
Correct answer: Pulse oximeter
Pulse oximetry provides continuous monitoring of blood oxygen saturation to ensure adequate oxygenation during anesthesia.
Question 4: Which medication is commonly used for induction of anesthesia?
- Lidocaine
- Propofol (Correct answer)
- Epinephrine
- Furosemide
Correct answer: Propofol
Propofol is a short-acting intravenous anesthetic commonly used for induction due to its rapid onset and smooth recovery profile.
Question 5: What is the purpose of neuromuscular blocking agents during anesthesia?
- To relieve pain
- To provide muscle relaxation for surgery and intubation (Correct answer)
- To increase blood pressure
- To prevent nausea
Correct answer: To provide muscle relaxation for surgery and intubation
Neuromuscular blocking agents relax skeletal muscles, facilitating endotracheal intubation and improving surgical conditions.
Question 6: Why is capnography used during anesthesia?
- To monitor blood sugar levels
- To assess ventilation and detect airway issues (Correct answer)
- To measure blood pressure
- To track heart rhythm
Correct answer: To assess ventilation and detect airway issues
Capnography measures end-tidal CO2 levels, ensuring proper ventilation and detecting airway complications early.
