Learning Objectives
By the end of this lesson, you will be able to:
- Explain why training and planning matter more than any individual piece of gear
- Assemble a core wilderness first aid kit and justify each item by the skill it supports
- Select appropriate over-the-counter medications and state the scope rules for helping with them
- Scale a kit by time-to-help, trip length, group size, and activity
- Prepare a group before a trip: medical information, communication plan, and kit maintenance
Every skill in this course has a physical counterpart: bleeding control needs gauze and a tourniquet, splinting needs something rigid and something soft, and calling for rescue needs a device that works where you're going. This lesson closes the loop — it turns the course into a packing list.
This lesson pairs with the course's interactive kit checklist, which you can tick off as you build your own kit and print for restocking.
Key Points
Kit Principles
Skills Over Stuff
Ask one question about every item before it earns a place in your pack: "Have I practiced using this?" A tourniquet you have never applied, a splint you have never molded, or a wound-closure strip you have never placed is dead weight — or worse, a source of false confidence. Buy less, practice more.
Scale by Time-to-Help
The right kit size is driven less by how many days you'll be out than by how long help would take to reach you. An afternoon in a remote canyon may justify more kit than a week of car camping near a town.
| Trip | Adjust the baseline |
|---|---|
| Short day hike, front-country | Trim to gloves, bleeding control, blister care, basic meds, whistle, phone |
| Full day, remote | The full core kit; add a satellite messenger if you'll be out of coverage |
| Multi-day backcountry | Double consumables (gauze, gloves, meds); add a low-reading thermometer and repair items |
| Group or trip leader | Scale consumables by head count; collect medical information from every member before leaving; carry group shelter |
Protect the Kit Itself
- Waterproof everything. Wet gauze is no gauze. Use dry bags or zip-top bags — the bags themselves double as irrigation reservoirs and improvised ice packs.
- Organize for the emergency, not the shelf. Bleeding-control items belong on top where you can grab them with shaking hands. Group items by problem, not by size.
- Know your kit blind. You may be opening it in the dark, in the rain, with cold fingers. Repack it the same way every time.
- Restock after every trip. The gauze you used last time is the gauze you won't have next time. Check medication expiration dates seasonally.
Key Points
The Core Kit
A solid day-trip baseline for two people, organized by the problem each group solves. Each maps to the lesson that teaches its use — if a line surprises you, that's the lesson to review.
Protect Yourself — Lesson 1
- Nitrile gloves, 3–4 pairs — not latex (allergy risk); they tear, so carry spares
- CPR barrier mask — pocket mask or keychain shield
- Hand sanitizer — before and after patient contact
Stop Bleeding — Lesson 4
- Gauze pads (4×4"), 6+ — direct pressure is the workhorse
- Roller gauze, 2 rolls — holds pressure dressings in place
- Commercial tourniquet (CAT-style) — for limb bleeding that pressure can't control; practice before you need it
- Hemostatic gauze (optional) — for junctional wounds a tourniquet can't reach; pack and hold pressure
Wound Care — Lesson 4
- Irrigation syringe (10–20 mL) — pressure irrigation with clean water is the single best infection preventer
- Adhesive bandages, wound closure strips, non-adherent pads
- Antibiotic ointment or petroleum jelly — single-use packets stay clean
- Medical tape — cloth tape holds when skin is wet
- Blister kit — moleskin or kinesiology-style tape; the most-used item in any hiking kit
Bones & Joints — Lesson 6
- Moldable splint (SAM-style) — one splint, dozens of configurations
- Elastic wrap (3–4") — sprains, securing splints, pressure dressings
- Triangular bandages, 2 — slings, swathes, and ties
Tools & Documentation
- Trauma shears — cut clothing off, not around (Lesson 2: expose to assess)
- Fine-point tweezers — splinters and tick removal (Lesson 12)
- SOAP note forms and a pencil — print the course field reference card; pencil writes wet and cold (Lesson 1)
- Headlamp, emergency blanket or bivy, duct tape — light, shock care and hypothermia wrap (Lesson 9), and repairs
Call for Help — Lesson 13
- Whistle — three blasts signals distress; carries farther than your voice, forever
- Phone with backup battery — airplane mode preserves it
- Satellite messenger or PLB — for genuine remoteness, the highest-value item in the kit
- Paper map — you can't give rescuers a location you don't know
Key Points
Medications & Scope
Over-the-Counter Basics
| Medication | What it's for | Course link |
|---|---|---|
| Ibuprofen | Pain, swelling, inflammation | Lesson 6 |
| Acetaminophen | Pain and fever when NSAIDs aren't a fit | — |
| Aspirin | Suspected heart attack | Lesson 11 |
| Diphenhydramine | Allergic reactions — after epinephrine in anaphylaxis, never instead of it | Lesson 10 |
| Antacid, anti-diarrheal | GI problems end more trips than trauma does | — |
| Oral rehydration salts | Heat illness and GI fluid losses | Lesson 8 |
Scope Rules for a Wilderness First Aider
- You may offer over-the-counter medications at package doses to an alert adult who consents — show them the label.
- You may assist a patient with their own prescribed medications: their epinephrine auto-injector (Lesson 10), their inhaler, their nitroglycerin.
- You do not carry or administer prescription medications that aren't yours or the patient's.
- Never give anything by mouth to a patient who is not fully alert or cannot swallow safely (Lesson 5).
Pre-Trip Preparation
- Group medical information: before the trip, collect each member's allergies, medications, and relevant history — SAMPLE, gathered in advance (Lesson 2). Know who carries an epinephrine auto-injector or inhaler, and where.
- Communication plan: know your coverage, program local emergency contacts, and leave a trip plan with someone at home: route, party size, return time, and when to call for help if you're overdue (Lesson 13).
- Kit check: restock consumables, replace expired medications, and confirm every group member knows where the kit rides in the pack.
Key Points
Scenarios
Setting: A friend hands you a large, brand-new commercial first aid kit at the trailhead for a remote day hike: "We're covered — this thing has everything." Flipping through it, you find one pair of vinyl gloves, thirty adhesive bandages, a foil blanket, ointment packets, a triangular bandage — but no irrigation syringe, no tourniquet, one small roll of gauze, and no medications beyond aspirin.
Questions to consider:
- What can this kit actually treat well, and what can't it?
- Which gaps matter most for a remote day hike?
- What would you add from your own supplies before leaving the trailhead?
Analysis: This kit handles small cuts and blisters — the most common problems — but not the most dangerous ones. It cannot stop serious bleeding (one gauze roll, no tourniquet), cannot properly clean a backcountry wound (no irrigation), and offers little for allergic reactions or pain.
Priority additions: more gauze and a tourniquet, an irrigation syringe (or a spare zip-top bag with a pinhole as a field improvisation), nitrile gloves in several pairs, and OTC medications including diphenhydramine and ibuprofen. Check who in the group carries prescription epinephrine or an inhaler and where it is.
Key point: Judge a kit by the worst problem it must handle at that distance from help — not by how many pockets it has.
Setting: You're leading five friends on a three-day rafting trip on a remote river — no road access between the put-in and take-out, no cell coverage in the canyon. You're assembling the group kit the week before.
Questions to consider:
- How does this trip change the kit compared to your solo day-hike baseline?
- What preparation matters beyond the physical kit?
- What activity-specific risks should shape your choices?
Analysis: Six people, three days, no exit, no coverage — every scaling factor points up. Consumables scale by head count; time-to-help means a satellite messenger is close to mandatory (Lesson 13); the river environment adds drowning and cold-water immersion risk (Lesson 14) and guarantees everything gets wet.
Kit changes: double-bagged dry storage; a full hypothermia setup (insulation layer, blanket or bivy, sugar-rich food — Lesson 9); doubled gauze, gloves, and medications; a low-reading thermometer; blister and sun care for six.
Preparation: collect SAMPLE-style medical information from all five friends before the trip; confirm who carries prescription epinephrine or inhalers and brief the group on where they ride; file a trip plan with a contact at home including the overdue-call time; agree on a communication schedule if the messenger supports check-ins.
Key point: On a group trip, the leader's most important first aid work happens before anyone gets in the boat.
