((If trainees do not assess lower limb neurological function before attempting to move the patient — prompt: 'Before repositioning him, what neurovascular checks should you perform?'))

((If trainees do not ask about bowel and bladder symptoms — prompt: 'In a back injury patient, are there specific symptoms that would suggest urgent spinal cord involvement?'))

((If trainees attempt to stand the patient upright immediately — patient cries out and is unable to stand. Prompt: 'The patient is in severe pain — how can you best manage his comfort while completing your assessment?'))

((If trainees are concerned about the BP reading — prompt: 'His BP is elevated — what are the likely contributing factors here? Does this change your immediate management?'))

Acute lumbar paraspinal muscle strain from heavy lifting. No neurological deficit identified. No red flag features for serious spinal pathology — no leg radiation or weakness, no bowel/bladder dysfunction, no fever, no unexplained weight loss, mechanism clearly mechanical. Mildly elevated BP is consistent with pain response and known hypertension, not a primary vascular emergency. This is a painful but not life-threatening musculoskeletal injury within EHS supportive management scope.

• Ensure scene safety — assess equipment staging area for hazards.
• Don appropriate PPE.
• Perform Primary Survey — confirm no life-threatening injuries.
• Obtain history — confirm mechanism (heavy lifting, sudden onset), pain character (localised lower back, no leg radiation), prior back history, red flag screen (no neurological symptoms, no bowel/bladder change, no constitutional symptoms).
• Assess lower limb neurological function — confirm sensation (light touch bilateral feet and legs), voluntary movement (ask patient to wiggle toes and move ankles), and ask about any numbness or tingling; confirm nil deficit.
• Ask specifically about bowel and bladder function — nil dysfunction in this scenario (important red flag screen for cauda equina).
• Palpate the lumbar spine — assess for midline bony tenderness (nil in this scenario); note bilateral paraspinal muscle spasm and guarding.
• Confirm absence of red flags for serious spinal pathology — nil bilateral leg weakness or paraesthesia, nil bowel/bladder dysfunction, nil fever, nil unexplained weight loss, mechanism clearly mechanical.
• Document pain score — 8/10.
• Position patient in position of comfort — lateral position on the ground is typically most tolerable for acute back strain; do not force upright positioning.
• Consider Methoxyflurane (Penthrox) for pain management — appropriate if patient is cooperative, pain is limiting assessment, and patient can self-administer.
• Monitor vital signs — note mildly elevated BP consistent with pain and known hypertension; repeat after analgesia.
• Once pain is more manageable — assist patient to a supported sitting or lying position at the FAP; arrange wheelchair transport if needed.
• Reassure patient — neurological function is intact, no red flags are present, this is consistent with an acute muscle strain.
• Advise patient — he should see a GP or physiotherapist for ongoing management; he should avoid heavy lifting while symptomatic.
• Contact CSP if neurological deficit develops, red flags emerge, or pain is unmanageable.
• Scenario ends when patient is in a position of comfort, analgesia has been provided, and neurovascular status is confirmed intact.
• Attention to hand hygiene will be given throughout the scenario.
