Question 1
Why is a measure of serum lactate obtained in the initial assessment
of the trauma patient?
A) To measure oxygenation and ventilation
B) To quantify the base deficit for the adequacy of cellular perfusion
C) To gauge end-organ perfusion and tissue hypoxia
D) To determine the underlying cause of shock
Answer: C
Rationale: Serum lactate is a marker of anaerobic metabolism that occurs
when tissues are hypoperfused. Elevated lactate indicates inadequate tissue
oxygenation and end-organ perfusion, making it a valuable indicator of
shock severity. While lactate correlates with base deficit, its primary utility is
as a marker of tissue hypoxia and hypoperfusion, not as a direct measure of
oxygenation/ventilation or as a diagnostic tool for shock etiology.
Question 2
A trauma patient is restless and repeatedly asking "where am I?" Vital
signs upon arrival were BP 100/60 mm Hg, HR 96 beats/min, and RR
,24 breaths/min. Her skin is cool and dry. Current vital signs are BP
104/84 mm Hg, HR 108, RR 28 breaths/min. The patient is
demonstrating signs and symptoms of which stage of shock?
A) Compensated
B) Progressive
C) Irreversible
D) Decompensated
Answer: A
Rationale: The patient is in compensated shock, characterized by the
body's compensatory mechanisms attempting to maintain perfusion to
vital organs. Signs include:
• Restlessness and anxiety (cerebral hypoxia)
• Narrowing pulse pressure (from 40 to 20 mmHg)
• Tachycardia
• Tachypnea
• Cool, dry skin (peripheral vasoconstriction)
The narrowed pulse pressure is a key indicator of compensated shock.
Progressive shock would show worsening hypotension and organ
dysfunction, while irreversible shock would demonstrate unresponsiveness
to treatment.
Question 3
An elderly patient with a history of anticoagulant use presents after a
fall at home that day. She denies any loss of consciousness. She has a
, hematoma to her forehead and complains of headache, dizziness, and
nausea. Which is the most likely cause of her symptoms?
A) Epidural hematoma
B) Diffuse axonal injury
C) Post-concussive syndrome
D) Subdural hematoma
Answer: D
Rationale: Subdural hematoma is most likely in this scenario for several
reasons:
• Elderly patients have cerebral atrophy, which stretches bridging veins
• Anticoagulant use increases bleeding risk
• Falls are a common mechanism
• Insidious onset with delayed symptoms (hours to days)
• Headache, dizziness, and nausea are classic symptoms
Epidural hematomas typically present with a lucid interval followed by
rapid deterioration and are associated with arterial bleeding (often middle
meningeal artery). Diffuse axonal injury results from rotational forces and
causes more significant neurological deficits.
Question 4
EMS brings a patient who fell riding his bicycle. Using the American
College of Surgeons screening guidelines, which assessment finding
would prompt the nurse to prepare the patient for radiologic spine
clearance?
