for trauma nursing certification. Questions emphasize practical assessment, interventions, and
rationales. Each includes multiple-choice options where applicable, the correct answer, and
a concise rationale. Content is streamlined for clarity and direct application in trauma care,
ensuring a comprehensive 60+ page document for download as a PDF.
2 Questions 1-100
Question 1: You are caring for a patient thrown from a bike without a helmet. During head-
to-toe assessment, clear drainage from the right ear is noted. What is the most appropriate next
step?
A. Clean the ear with a cotton-tipped applicator.
B. Pack the ear with gauze.
C. Notify the physician.
D. Apply a pressure dressing.
Correct Answer: C. Notify the physician.
Rationale: Clear drainage from the ear may indicate cerebrospinal fluid leak from a basilar
skull fracture. Immediate physician notification is essential to prevent infection and guide
further imaging or intervention, avoiding manipulation that could worsen the injury.
Question 2: A patient arrives at a rural ED after a high-speed MVC with significant abdominal
and pelvic injuries noted in the primary survey. What is the priority intervention?
A. Perform a FAST exam.
B. Administer pain medication.
C. Initiate transfer to a trauma center.
D. Insert a Foley catheter.
Correct Answer: C. Initiate transfer to a trauma center.
Rationale: Rural facilities may lack resources for complex trauma. Early transfer ensures
1
,access to surgical capabilities, stabilizing the patient en route while addressing life threats.
Question 3: An adult falls from a second-story roof, arrives confused with unlabored respira-
tions, strong radial pulses, and an open wound near a left lower extremity deformity. What is
the priority intervention?
A. Splint the extremity.
B. Administer IV fluids.
C. Initiate cervical spine stabilization.
D. Obtain vital signs.
Correct Answer: C. Initiate cervical spine stabilization.
Rationale: Confusion suggests possible head or spine injury from the fall height. Stabilizing
the cervical spine prevents further damage during assessment and transport.
Question 4: An intubated adult with severe head trauma is manually ventilated at 18 breaths/min,
received 500 mL fluid bolus, PaCO2 30 mm Hg, SpO2 92%, BP 142/70 mm Hg. What man-
ages cerebral blood flow best?
A. Increase ventilation rate.
B. Administer mannitol.
C. Decrease ventilation rate.
D. Elevate head of bed.
Correct Answer: C. Decrease ventilation rate.
Rationale: Low PaCO2 causes cerebral vasoconstriction, reducing blood flow. Slowing venti-
lation to target PaCO2 35-45 mm Hg improves perfusion without risking hypercapnia.
Question 5: An adult post-rollover MVC with prolonged extrication has swelling/bruising on
right proximal thigh, weak pedal pulse, pale/cool/moist skin. What initial intervention?
A. Elevate the leg.
B. Apply pelvic binder.
C. Start IV fluids.
D. Obtain X-ray.
Correct Answer: B. Apply pelvic binder.
Rationale: Proximal thigh injury with hemodynamic instability suggests pelvic fracture. Binder
stabilizes the pelvis, reducing volume loss from bleeding.

, Question 6: Adult with superficial burns to extremities post-house fire reports headache, nau-
sea, drowsy/confused. Likely cause?
A. Hypovolemia.
B. Inhalation injury.
C. Carbon monoxide poisoning.
D. Pain response.
Correct Answer: C. Carbon monoxide poisoning.
Rationale: CO binds hemoglobin, causing hypoxia mimicking these symptoms. Burns in fire
suggest exposure; immediate 100% oxygen is key.
Question 7: Using ACS guidelines for spine injury screening, what finding prompts cervical
spine imaging?
A. Alert and oriented.
B. No neck pain.
C. Responds to verbal stimulation (AVPU).
D. Normal motor function.
Correct Answer: C. Responds to verbal stimulation (AVPU).
Rationale: Altered mental status (verbal response only) increases risk of missed injury. Imag-
ing is indicated if criteria not fully met.
Question 8: 5-month pregnant patient trips, falls on abdomen; bruising to abdomen, arms,
neck; no prenatal care. Likely related to?
A. Accidental fall.
B. Intentional violence.
C. Medication side effects.
D. Nutritional deficiency.
Correct Answer: B. Intentional violence.
Rationale: Multiple bruises in various stages suggest abuse. Lack of prenatal care raises red
flags; screen sensitively and report.
Question 9: Unconscious multi-system trauma patient has snoring respirations in primary sur-
vey. Next priority?
