BCEN Trauma and Injury Management 3 — Questions and Answers
Question 1: A patient with a stab wound to zone II of the neck is hemodynamically stable. The appropriate initial management is:
- Immediate surgical exploration
- Computed tomography angiography (CTA) of the neck (Correct answer)
- Blind digital exploration of the wound
- Observation only for 24 hours
Correct answer: Computed tomography angiography (CTA) of the neck
Hemodynamically stable patients with zone II neck injuries undergo CTA to evaluate vascular and aerodigestive structures before surgical decisions.
Question 2: Which intervention is CONTRAINDICATED in a patient with a suspected basilar skull fracture?
- Nasogastric tube insertion (Correct answer)
- Orotracheal intubation
- IV fluid resuscitation
- CT scan of the head
Correct answer: Nasogastric tube insertion
Nasogastric tube insertion is contraindicated in basilar skull fracture due to risk of intracranial placement through the cribriform plate.
Question 3: A burn patient has circumferential full-thickness burns to both lower extremities with absent distal pulses. The priority intervention is:
- Increase IV fluid rate immediately
- Perform escharotomy (Correct answer)
- Apply compression dressings
- Administer vasopressors
Correct answer: Perform escharotomy
Circumferential full-thickness burns cause compartment syndrome requiring escharotomy to restore distal perfusion.
Question 4: According to the Parkland formula, how much fluid should be given in the first 8 hours for a 70 kg patient with 40% TBSA burns?
- 2,800 mL
- 5,600 mL (Correct answer)
- 11,200 mL
- 8,400 mL
Correct answer: 5,600 mL
Parkland formula: 4 mL × kg × %TBSA = 4 × 70 × 40 = 11,200 mL total; half (5,600 mL) given in first 8 hours.
Question 5: A pedestrian struck by a vehicle presents with ecchymosis in a 'tire track' pattern across the abdomen and pelvis. The nurse anticipates injury to which organ most commonly?
- Liver
- Spleen
- Small bowel and mesentery (Correct answer)
- Bladder
Correct answer: Small bowel and mesentery
Crush injury from tire tracks most commonly injures the small bowel and mesentery due to compression against the spine.
Question 6: A patient presents with a gunshot wound to the abdomen, evisceration of bowel, and hemodynamic instability. The appropriate wound management prior to surgery is:
- Attempt to reduce the bowel back into the abdomen
- Cover with a moist saline dressing or bowel bag (Correct answer)
- Apply a dry sterile dressing with pressure
- Leave the wound open to air until OR is ready
Correct answer: Cover with a moist saline dressing or bowel bag
Eviscerated bowel should be covered with a moist saline dressing or bowel bag to prevent desiccation; never attempt to replace it.
Question 7: Which mechanism best explains why elderly trauma patients have higher mortality than younger patients with similar injury severity scores?
- Elderly patients refuse treatment more often
- Reduced physiologic reserve and higher rates of anticoagulant use (Correct answer)
- Emergency nurses triage elderly patients as lower priority
- Elderly patients have more pain sensitivity causing vasovagal responses
Correct answer: Reduced physiologic reserve and higher rates of anticoagulant use
Reduced physiologic reserve, comorbidities, and common anticoagulant use impair the elderly patient's ability to compensate for traumatic injury.
A patient with a stab wound to zone II of the neck is hemodynamically stable.
The appropriate initial management is:
