Case Analysis & Practical Application Flashcards

A 14-year-old snowboarder presents with wrist pain after a FOOSH (fall on outstretched hand) injury. X-ray is not available. Which physical finding would most concern you for a scaphoid fracture versus a distal radius fracture?

Answer: Tenderness in the anatomical snuffbox with pain on axial loading of the thumb

Anatomical snuffbox tenderness with axial thumb loading pain is the classic field indicator of scaphoid fracture, which has high risk of avascular necrosis if missed.

During a wilderness search and rescue, you find a hiker who has been missing for 3 days in summer heat. He is responsive to pain only, has dry mucous membranes, sunken eyes, tenting skin, HR 130, and BP 80/50. What is your immediate field priority?

Answer: Intravenous fluid resuscitation if available, and rapid evacuation

Severe dehydration with hemodynamic compromise requires IV fluid resuscitation; if IV access is unavailable, intraosseous access should be considered and rapid evacuation is essential.

A kayaker is pulled from a river after a swim in Class IV rapids. She is responsive and breathing but has obvious bruising across her chest from her PFD straps. What injury pattern should you suspect?

Answer: Traumatic aortic injury or myocardial contusion from deceleration force

Seat belt/PFD strap bruising patterns indicate significant deceleration forces capable of causing traumatic aortic injury, myocardial contusion, or other thoracic organ injuries.

A backcountry skier develops confusion, ataxia, and severe headache after rapid ascent to 12,000 feet. You suspect HACE. What is the most critical initial intervention?

Answer: Immediate descent of at least 1,000–2,000 feet

HACE is immediately life-threatening; descent is the definitive treatment and must begin immediately — adjuncts like dexamethasone and Gamow bag support but do not replace descent.

A patient with insulin-dependent diabetes becomes unresponsive during a 3-day backpacking trip. You cannot establish IV access. Which field intervention is most appropriate for presumed hypoglycemia?

Answer: Place glucose gel or honey inside the cheek and monitor airway carefully

In an unresponsive hypoglycemic patient without IV access, glucose gel or honey placed between the cheek and gum can be absorbed transdermally while monitoring the airway.

While treating a patient with a suspected cervical spine injury, a team member suggests a rapid extrication due to an approaching wildfire. What principle guides this decision?

Answer: A scene hazard that threatens life justifies modified or rapid extrication even at risk to the spine

Scene safety is the first priority; an immediate life threat (fire, avalanche, etc.) justifies rapid extrication using best available manual stabilization even if full spinal precautions cannot be maintained.

A nordic skier presents with labored breathing, pink frothy sputum, and crackles in both lung bases after strenuous exercise at high altitude. What condition is most likely?

Answer: High Altitude Pulmonary Edema (HAPE)

Pink frothy sputum, bibasilar crackles, and respiratory distress at altitude after exertion is classic High Altitude Pulmonary Edema (HAPE), requiring immediate descent and supplemental oxygen.
