- 391 SBA questions covering all 69 units of the PHEM curriculum
- 26 timed stations: 18 of 8 minutes and 8 of 16, as in Part B
- Every answer sourced: chapter and page for books, and links that open guidelines at the right page or section
Every answer shows where it comes from
When you answer a question, the explanation tells you why, and "Where this comes from" tells you where to read more:
- Books: the textbook and page, e.g. Oxford Handbook of Pre-Hospital Care, pp. 159–160.
- Guidelines: the Resuscitation Council UK section or NICE recommendation.
- Consensus statements: the FPHC statement, opened at the right page of the PDF.
- Law: the Act and section on legislation.gov.uk.
If you get a question wrong, add its sources to your reading list and tick them off as you go.
A fire service watch manager asks a HEMS doctor how common spinal cord injury actually is among people trapped in cars, since the crew's training has emphasised movement minimisation above everything else. According to the data underpinning the FPHC EXIT consensus statement on extrication, approximately what proportion of trapped patients have a spinal cord injury?
Correct — the answer is A
0.7%
The EXIT project data that underpin the Faculty of Pre-Hospital Care's extrication consensus show that approximately 0.7% of patients trapped following a motor vehicle collision have a spinal cord injury. That low figure underpins the consensus's central shift: all patients with injury should be considered time dependent, and the extrication plan should be built around minimising entrapment time rather than absolute movement minimisation. The same work found that trapped patients are more severely injured than those not trapped (median injury severity score 18 against 13) and have higher mortality; that female patients are more likely to be trapped than males; and that older patients have an excess mortality associated with entrapment. The biomechanical study found the smallest cervical movement with self-extrication (2.6 mm) and the largest with rapid extrication (6.21 mm).

How it works
- Practise. Choose Part A-style SBA papers of 10, 20 or 60 questions (one minute a question), in Learn mode or Exam mode. Or run a branching station against an 8- or 16-minute clock.
- Review with sources. See why the best answer is best, why the others are not, and exactly where to read.
- Build your reading list. Save the passages behind the questions you got wrong. Your dashboard tracks your weakest domains and suggests what to do next.
Current, UK-focused content
Questions are written to current UK practice, as the exam requires. That means:
- Resuscitation Council UK Guidelines 2025
- Ten Second Triage, which replaced the triage sieve in 2023
- NICE NG253 for sepsis
- the current FPHC consensus statements
Where an older textbook and a newer guideline disagree, the explanation says so.
