A study tool, not a substitute for a hands-on class

First Aid
Study Center

A reference guide to what to do in the first minutes of an emergency, plus 3 quizzes — 150 questions in all — on resuscitation, bleeding and trauma, and the sudden illnesses that arrive without a visible injury. Every quiz breaks your score down by theme, so a poor result tells you exactly what to re-read. Nothing here replaces a real class with an instructor and a manikin, and in an emergency the instruction that overrides everything else is: call 911.

The Reference Guide

The first sixty seconds of any emergency, CPR and the defibrillator, choking, severe bleeding, burns, spinal injury, stroke, heart attack, anaphylaxis, overdose, seizures, heat and cold, poisoning and diabetic crises. Every figure is checked against a named source, and where the authorities disagree the guide shows the disagreement rather than picking a winner. Every quiz below comes from a section of it.

The Quizzes

In the order the guide covers them. Each one stands on its own — start wherever the subject interests you.

50 Questions

CPR and the AED

Recognising cardiac arrest and doing something about it: agonal gasping, the compression rate and depth from the 2025 guidelines, hands-only CPR, the different numbers for children and infants, using a defibrillator, and the choking sequence the AHA rewrote in October 2025.

Bleeding and Trauma

The injuries where a bystander most reliably changes the outcome: direct pressure, wound packing and tourniquets, cooling burns, leaving a suspected spinal injury where it lies, fractures and sprains, and what actually belongs in a first aid kit.

Medical Emergencies

The emergencies that arrive without a visible injury: stroke and heart attack, anaphylaxis and the auto-injector, opioid overdose and naloxone, seizures, heat and cold, poisoning, and diabetic crises.

How these were built

Each quiz expands one part of the reference guide into 50 questions grouped into six themes. Options are reshuffled every time you start, and every set was checked against all the others so no question is asked twice. One deliberate constraint runs through all of them: the four options are kept close in length, so the longest answer is never a giveaway. Across all 150 questions the correct answer is the longest option 24 per cent of the time — which is what chance would give you.

Where the guidance comes from

First aid guidance is revised on a cycle, and these questions were checked in August 2026. The American Heart Association published new resuscitation guidelines on 22 October 2025 which changed the choking sequence and eliminated the two-finger technique for infants; the AHA and Red Cross revised the first aid guidelines in November 2024. Where bodies genuinely disagree — how long to cool a burn, whether to take aspirin for chest pain, how long the stroke treatment window runs — the questions test the disagreement rather than inventing a consensus. Confirm current practice with a certifying organization before relying on any of it.
