WFR: Trauma (4) questions with
complete solutions rated A+ passed
What type of events are most likely to cause multi-system trauma? - correct answer ✔✔High velocity,
rapid deceleration events
What type of events are most likely to cause local injury? - correct answer ✔✔Low-velocity, high mass
events
T/F: Problems associated with trauma tend to be isolated in the backcountry. - correct answer ✔✔False:
tendency is for cumulative
What are some high-energy mechanisms that are likely to result in significant multi-system trauma? -
correct answer ✔✔High-velocity rapid deceleration events like...
Fast skier hits tree.
Climber falls from 15m and hits ground.
What mechanisms are more likely to cause only localized trauma? - correct answer ✔✔Low-velocity,
high mass events
Slow skiier hits tree
Climber falls from 4m and hits ground
What is cavitation? - correct answer ✔✔High velocity trauma that causes a shift in internal organs.
What is contra-coup injury? - correct answer ✔✔Brain doesn't slow during rapid deceleration causing it
to tear from the arteries and veins.
,How does trauma happen? (science) - correct answer ✔✔Body absorbs to much kinetic energy too
quickly.
What is the risk associated with fluid replacement if bleeding not resolved? - correct answer ✔✔If
bleeding not controlled and patient is an A on AVPU: no fluids.
Dilutes blood and may prevent clotting.
What is the most important BLS to perform for a trauma patient? - correct answer ✔✔Maintain normal
core body temp and (if internal bleeding suspected) get them to the hospital
What is the most effective form of pain relief? - correct answer ✔✔To correct the cause
If you treat pain as a symptom, what must you stay aware of? - correct answer ✔✔The original problem
may still remain and must be addressed.
No pain does not equate to no problem when medicating.
What are the two basic forms of pain medications? - correct answer ✔✔Analgesics: reduces pain
impulses (brain)
Anesthetics: numbs origin of pain
What are the three classes of analgesics? - correct answer ✔✔1. NSAIDs (ibuprofen, naproxen)
2. Non-opioid analgesics (acetaminophen)
3. Opioids: (morphine, hydrocodone)
What are some effects of NSAIDs? - correct answer ✔✔+ : doesn't effect brain function, widely available,
treat pain, inflammation and fever
- : stomach irritation, increased bleeding
, What are some effects of non-opioid analgesics? (acetaminophen) - correct answer ✔✔+ : pain relief,
fever reduction, no upset stomach
- : doesn't treat inflammation
What are some effects of opioids? - correct answer ✔✔+ : strong pain relief for moderate to severe
- : depress brain function, depressed respiratory function, gut motility (constipation), suppressed
shivering, when used in adjunct with benzodiazepines can be fatal
What type of anesthetics can wilderness practitioners use? - correct answer ✔✔Topical
What is the goal of pain management in the wilderness? - correct answer ✔✔Awake patient with
tolerable pain.
Explain the risk of self inflicted injury when managing pain: - correct answer ✔✔Medicated patients may
not be able to use their pain response to keep their body safe since they cannot feel the pain feedback.
What is the structure of the musculoskeletal system? - correct answer ✔✔Bone
Cartilage
Tendon
Ligament
Muscle
Synovial fluid
Define fascia: - correct answer ✔✔connective tissue encasing muscles
Name 3 MOI of musculoskeletal injuries: - correct answer ✔✔direct force
indirect force
overuse
