6 worked Anesthesia Technologist practice questions
Original exam-style questions from the bank, spread across the blueprint domains. They are not real or recalled exam questions. Try each one, then open the answer for the rationale and reference. None of them appear in the free mock exam, so reading them will not spoil it.
Question 1 · Airway management equipment and assistance
Using the usual formula, what cuffed tracheal tube size is suitable for a 4-year-old child?
- A5.0 mm
- B4.5 mm
- C5.5 mm
- D3.5 mm
Show answer and explanation
Correct answer: B. 4.5 mm
For cuffed tubes, internal diameter = age/4 + 3.5 = 1 + 3.5 = 4.5 mm. The uncuffed formula (age/4 + 4) gives 5.0 mm.
Reference: APLS: The Practical Approach, 6th ed.
Question 2 · Anaesthesia machine, breathing systems and gas supply
What is the purpose of the pin index safety system on small medical gas cylinders?
- AIt shows how much gas is left in the cylinder
- BIt prevents a cylinder being fitted to the wrong gas yoke
- CIt reduces the cylinder pressure to a safe level
- DIt detects leaks at the cylinder valve
Show answer and explanation
Correct answer: B. It prevents a cylinder being fitted to the wrong gas yoke
Each gas has a unique pin position on the yoke that matches holes on the cylinder valve, so a wrong cylinder cannot be fitted. Pressure regulators reduce pressure and gauges show contents.
Reference: Ward's Anaesthetic Equipment, 6th ed.
Question 3 · Anaesthesia machine, breathing systems and gas supply
Why do modern vaporisers use keyed, agent-specific filling systems?
- ATo speed up refilling between cases
- BTo allow mixing of two agents together
- CTo prevent filling with the wrong volatile agent
- DTo cool the liquid agent during filling
Show answer and explanation
Correct answer: C. To prevent filling with the wrong volatile agent
Vaporisers are calibrated for one agent, and filling with the wrong agent can deliver a dangerous over- or under-dose. Keyed fillers prevent this error.
Reference: Ward's Anaesthetic Equipment, 6th ed.
Question 4 · Emergencies and crisis support
An 80 kg patient has malignant hyperthermia. Dantrolene is supplied as 20 mg vials. How many vials are needed for the initial 2.5 mg/kg dose?
- A4 vials
- B10 vials
- C20 vials
- D8 vials
Show answer and explanation
Correct answer: B. 10 vials
2.5 x 80 = 200 mg, and 200 / 20 = 10 vials. Each 20 mg vial needs reconstitution with sterile water, so several team members are usually needed.
Reference: Association of Anaesthetists Malignant Hyperthermia Guideline 2020
Question 5 · Infection control, cleaning and sterilisation
How should a breathing system filter be used to protect the circle system between patients?
- AThe same filter is reused for the whole day
- BA new filter is placed at the patient end for each patient
- CThe filter is placed only at the gas outlet
- DA filter is not needed if the circuit is changed
Show answer and explanation
Correct answer: B. A new filter is placed at the patient end for each patient
A new heat and moisture exchanging filter at the patient end for each patient protects the breathing system from contamination, allowing the circuit to be changed according to local policy and manufacturer advice. Filters are single-patient items.
Reference: AAGBI Guidelines: Infection Prevention and Control 2020
Question 6 · Infection control, cleaning and sterilisation
What does a daily Bowie-Dick test on a pre-vacuum steam steriliser check?
- ABiological kill of spores
- BChemical residue on instruments
- CThe steriliser's water hardness
- DAir removal and steam penetration
Show answer and explanation
Correct answer: D. Air removal and steam penetration
The Bowie-Dick test checks that air is removed and steam penetrates the load, which is essential for porous-load sterilisation. Biological indicators test spore kill, and water quality is monitored separately.
