WFR - Wilderness First Responder Soft Tissue Injury Management Questions and Answers — Questions and Answers
Question 1: A hiker in your group sustains a deep, 10 cm laceration on their forearm from a fall on sharp rocks. The wound is bleeding steadily but not spurting. After applying direct pressure and elevating the limb, what is the most appropriate next step for wound cleaning in a wilderness environment?
- Pour hydrogen peroxide into the wound to disinfect it thoroughly.
- Scrub the inside of the wound vigorously with soap and a clean cloth.
- Leave the wound as is and apply a tight bandage to prioritize transport.
- Irrigate the wound with at least 0.5-1 liter of clean, potable water under pressure. (Correct answer)
Correct answer: Irrigate the wound with at least 0.5-1 liter of clean, potable water under pressure.
The standard of care in wilderness medicine for cleaning a contaminated wound is to irrigate it with a large volume of clean (potable) water under pressure. This mechanically removes dirt and bacteria. A syringe is ideal for creating pressure. Using antiseptics like hydrogen peroxide or iodine directly in the wound can damage healthy tissue and impair healing. While cleaning the skin around the wound is recommended, scrubbing inside can cause further tissue damage. Ignoring cleaning increases the risk of a serious infection, which is a major concern in a remote setting.
Question 2: Which of the following is the most appropriate treatment for a large, intact, and tense friction blister on a hiker's heel that is causing significant pain and preventing them from walking effectively?
- Drain the blister by puncturing it at its base with a sterilized needle, then apply a dressing. (Correct answer)
- Leave the blister intact and apply a thick donut-shaped moleskin pad around it to reduce pressure.
- Remove the entire roof of the blister to allow the underlying skin to dry and harden.
- Apply a hot compress to the blister to encourage it to burst and drain on its own.
Correct answer: Drain the blister by puncturing it at its base with a sterilized needle, then apply a dressing.
For a large, painful, and tense blister that is likely to rupture anyway, the recommended WFR protocol is to carefully drain it. This should be done by sterilizing a needle and piercing the blister at its base to allow for drainage by gravity. The roof of the blister should be left intact to act as a natural, protective dressing. While a donut pad can help with a small, non-tense blister, it is less effective for a large, painful one. Removing the roof exposes raw skin, increasing pain and infection risk. Hot compresses are not recommended and could cause a burn.
Question 3: A member of your party spills boiling water on their hand while cooking. The skin is red, painful, and has formed several small blisters. After stopping the burning process, what is the immediate and most critical treatment?
- Apply a thick layer of antibiotic ointment immediately.
- Wrap the hand tightly in a compression bandage to prevent swelling.
- Cool the burn with cool (not ice-cold) water for at least 20 minutes. (Correct answer)
- Pop the blisters to release the fluid and reduce pressure.
Correct answer: Cool the burn with cool (not ice-cold) water for at least 20 minutes.
The immediate and most important first aid for a thermal burn is to stop the burning process by cooling the area. This should be done with cool running water or compresses for a minimum of 20 minutes if possible. This action limits the depth of the burn and provides significant pain relief. Applying ointments immediately can trap heat. Tight bandages are inappropriate, and blisters should generally be left intact as they provide a sterile barrier.
Question 4: When managing a musculoskeletal injury like a sprained ankle in a remote wilderness setting, the acronym RICE (Rest, Ice, Compression, Elevation) is often recommended. What is the primary purpose of the 'Ice' component in the initial hours after the injury?
- To accelerate the healing process by increasing blood flow.
- To prevent infection in any associated abrasions.
- To reduce pain and control swelling. (Correct answer)
- To diagnose the severity of the ligament damage.
Correct answer: To reduce pain and control swelling.
In the context of the RICE protocol for acute soft tissue injuries, applying ice (or a cold pack) serves to constrict blood vessels, which helps to control swelling and inflammation. It also has an analgesic effect, numbing the area and reducing pain. While other protocols like MEAT and POLICE exist, the function of cold therapy in the immediate aftermath of an injury is primarily for pain and swelling management.
Question 5: Two days after sustaining a cut on the leg, a patient complains of increasing pain. You observe that the skin around the wound is red, swollen, and warm to the touch. What do these signs most strongly indicate?
- A normal healing process.
- A developing wound infection. (Correct answer)
- An allergic reaction to the bandage.
- The formation of a deep hematoma.
Correct answer: A developing wound infection.
The classic signs of a localized soft tissue infection are redness (erythema), swelling (edema), increased warmth, and pain. The presence of pus or foul-smelling drainage would further confirm this. While some minor redness is part of normal healing, the combination of these signs, particularly worsening pain and warmth, strongly suggests an infection that requires cleaning, drainage, and monitoring for evacuation.
Question 6: You are treating a patient with a moderate abrasion on their knee. After controlling minor bleeding and thoroughly cleaning the wound, which type of dressing is most appropriate to promote healing and prevent infection in a multi-day wilderness trip?
- A dry gauze dressing, left open to the air to form a scab.
- A dressing soaked in an iodine solution to continuously disinfect the wound.
- A moist, non-adherent dressing covered by a protective bandage. (Correct answer)
- Packing the wound with moss or other natural materials.
Correct answer: A moist, non-adherent dressing covered by a protective bandage.
Wounds heal best in a moist, clean environment. A non-adherent or occlusive dressing, possibly with antibiotic ointment or petroleum jelly, keeps the wound moist, which promotes tissue growth and reduces scarring. Leaving a wound open to form a dry scab can slow healing and increase the risk of cracking and infection. Continuous use of iodine can damage tissue, and using unsterilized natural materials introduces a high risk of infection.
