Sample questions
01What is the correct compression-to-breath ratio for adult CPR?
- A30 compressions to 1 breath
- B30 compressions to 2 breaths
- C20 compressions to 2 breaths
- D15 compressions to 2 breaths
Why: The Resuscitation Council UK recommends 30 chest compressions followed by 2 rescue breaths for adult CPR. This ratio applies whether there is one rescuer or two. It maximises coronary perfusion while still providing ventilation.
02How do you recognise cardiac arrest in a casualty?
- AThey have a weak pulse and are confused
- BThey are breathing rapidly and clutching their chest
- CThey are pale and sweating
- DThey are unresponsive and not breathing normally
Why: Cardiac arrest is recognised when a person is unresponsive and not breathing normally. You should not spend time trying to find a pulse as this is unreliable. If in doubt, start CPR immediately.
03What is the recommended depth of chest compressions for an adult?
- A3–4 cm
- B5–6 cm
- C2–3 cm
- D7–8 cm
Why: Chest compressions for an adult should depress the sternum by 5–6 cm. Compressions that are too shallow are ineffective at generating blood flow. Allow the chest to fully recoil between each compression.
Common questions
Is the First Aid at Work mock exam free?
Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.
Can I retake the mock exam?
Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.
Does this count towards the real qualification?
No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
