✍️ Sample EDAIC Questions & Answers
1. When positioning a double-lumen tube (DLT) for left-sided surgery, which side should the bronchial lumen be inserted into?
A left-sided DLT is preferred for most thoracic cases because the right upper lobe bronchus is easily blocked; for left pneumonectomy a right-sided DLT or bronchial blocker is used instead.
2. James Reason's 'Swiss cheese model' of accident causation is widely applied in patient safety. What does it describe?
In Reason's model, healthcare systems have multiple defensive barriers (like slices of cheese), each with latent holes (system weaknesses, not just individual errors). A critical incident occurs when holes in successive layers momentarily align, allowing a hazard to pass through all defences and cause harm. This model shifted safety thinking from 'blame the individual' to 'fix the system'.
3. Which coagulation abnormality is MOST commonly seen in advanced liver disease?
The liver synthesizes clotting factors II, VII, IX, and X (vitamin K-dependent); advanced liver disease impairs their production, prolonging PT/INR.
4. Which agent is used in a soda lime CO2 absorber and can degrade sevoflurane to produce the nephrotoxic compound Compound A?
Sodium hydroxide (NaOH) in soda lime reacts with sevoflurane to produce Compound A (fluoromethyl-2,2-difluoro-1-trifluoromethylvinyl ether).
5. A damped arterial line waveform (overdamped system) will produce which measurement error?
Overdamping attenuates the waveform peaks, causing underestimation of systolic and overestimation of diastolic pressure, while mean arterial pressure remains relatively accurate.
6. Which drug should be immediately available when performing test dose confirmation of epidural catheter placement?
Epidural test dose contains epinephrine 15 mcg; intravascular injection causes a transient heart rate increase >20 bpm, confirming misplacement.

What Practice Test Geeks adds beyond an AI chat for EDAIC
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length EDAIC mock exam — 120 questions in 180 minutes with a 60% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed EDAIC question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable EDAIC cheat sheet you can print or save as a PDF.
- EDAIC flashcards built from the same question bank.
- Free EDAIC practice tests with the correct answer shown after each question.
