Question 1

How long would it take to transport a patient on a M tank at 600 psi and 8 L/min of flow?

Accepted Answer

19.5 min

Answer

Using the M-tank formula — (tank pressure x tank factor) / flow rate — with the M-cylinder factor of about 1.56 L/psi: (600 x 1.56) / 8 ≈ 936 / 8, giving approximately 19.5 minutes of usable transport time. The other values result from using the wrong tank factor or arithmetic, so 19.5 min is correct.

Question 2

Nitrogen narcosis: what is it?

Accepted Answer

Caused by breathing in compressed nitrogen which is toxic to the CNS and causes confusion, slow motor, response, and  euphoria

Answer

Nitrogen narcosis is caused by breathing compressed nitrogen at depth, where the raised partial pressure has a toxic, anaesthetic effect on the central nervous system, producing confusion, slowed motor response, and euphoria. The other options describe drug uses, bone remodelling, and a beta-2 bronchodilator — none of which relate to the effect of compressed nitrogen on the CNS.

Question 3

Which five questions need to be addressed during a death investigation?

Accepted Answer

a)who was the deceased
b) by what means did the death occur
c) where did the death occur
d) when did the death occur
e) how did the death occur

Answer

A death investigation must establish the five core facts: who the deceased was, by what means, where, when, and how the death occurred. These mirror the basic 'who, what, when, where, how' framework used to fully reconstruct the circumstances. The other options describe neurotransmitters, cholinergic receptors, and steroid hormone action, which are unrelated to death investigation.

Question 4

What is decompression sickness type 1?

Accepted Answer

Caused by nitrogen bubbles collecting in the tissues and Causing puritis, Molting skin, and Skeletal muscle or Joint pain

Answer

Type 1 decompression sickness is the milder form, caused by nitrogen bubbles collecting in the skin, lymphatics, and musculoskeletal tissues, producing pruritus (itching), skin mottling/marbling, and joint or muscle pain ('the bends'). It spares vital organs, unlike Type 2 which affects the CNS, lungs, or heart. The wrong options describe Cushing's syndrome, pertussis, and measles.

Question 5

Which three stages make up trauma care?

Accepted Answer

1. Per incident
2. Incident
3. Post Incident

Answer

Trauma care is organized around the timing of the event: pre-incident (preparation and prevention), incident (the actual response and care delivered), and post-incident (recovery, transport, and follow-up). This logical before/during/after progression structures the entire care continuum. The other options describe cellular processes, brainstem functions, and migraine symptoms.
