TCAR (Trauma Care After Resuscitation) Final Exam
Practice Questions
1. A patient is admitted to the ICU following a motor
vehicle collision with multiple rib fractures and a
pulmonary contusion. Six hours after admission, the
patient’s oxygen saturation drops despite
supplemental oxygen. What is the most likely cause of
this deterioration? A. Pneumothorax expansion B.
Progression of pulmonary contusion and development of ARDS
C. Pulmonary embolism D. Aspiration pneumonia Correct
Answer: B Rationale: Pulmonary contusions often worsen
over the first 24–48 hours due to edema and inflammation,
leading to V/Q mismatch and potential Acute Respiratory
Distress Syndrome (ARDS). This is a classic "second hit"
phenomenon in trauma care.
2. Which of the following is the primary goal of the
"Secondary Survey" in the context of Trauma Care
After Resuscitation? A. To stabilize the airway and breathing
B. To identify all injuries through a head-to-toe examination
and history taking once the patient is hemodynamically stable
C. To initiate definitive surgical repair of all injuries D. To
transfer the patient to the ward immediately Correct
,Answer: B Rationale: The secondary survey occurs after
primary survey and resuscitation. Its goal is a thorough head-
to-toe assessment, including AMPLE history, to identify
missed or less obvious injuries that were not life-threatening
initially but require management.
3. A trauma patient with a severe traumatic brain
injury (TBI) has an Intracranial Pressure (ICP) of 25
mmHg. Which intervention is prioritized to lower ICP
while maintaining Cerebral Perfusion Pressure (CPP)?
A. Hyperventilation to a PaCO2 of 25 mmHg B. Elevating the
head of the bed to 30 degrees and ensuring neck midline
alignment C. Administering large volumes of hypotonic fluids
D. Placing the patient in the Trendelenburg position Correct
Answer: B Rationale: Elevating the head of the bed
promotes venous drainage from the brain, lowering ICP. Neck
midline alignment prevents jugular vein compression.
Hyperventilation is reserved for acute herniation signs due to
the risk of cerebral ischemia.
4. In the management of a patient with hemorrhagic
shock who has been resuscitated, what is the primary
concern regarding "Abdominal Compartment
Syndrome" (ACS)? A. Decreased urine output and increased
bladder pressure > 20 mmHg B. Increased bowel sounds C.
Hypertension and bradycardia D. Decreased peak inspiratory
pressures on the ventilator Correct Answer: A Rationale:
ACS is defined by sustained intra-abdominal hypertension
(IAH) with new organ dysfunction. Bladder pressure > 20
mmHg is a key diagnostic criterion. It compromises renal
perfusion (decreased urine output) and respiratory mechanics
(increased peak pressures).
5. Which laboratory value is most indicative of
ongoing tissue hypoperfusion and shock severity in a
trauma patient, even after blood pressure has
,normalized? A. Hemoglobin B. Lactate C. White Blood Cell
Count D. Platelet Count Correct Answer: B Rationale:
Lactate is a marker of anaerobic metabolism. Persistent
elevation indicates ongoing tissue hypoxia and inadequate
perfusion, even if vital signs appear stable ("occult shock").
6. A patient with a pelvic fracture is at high risk for
which specific complication during the resuscitation
and early ICU phase? A. Fat Embolism Syndrome B.
Retroperitoneal hemorrhage C. Compartment syndrome of the
arm D. Tension pneumothorax Correct Answer: B
Rationale: Pelvic fractures can cause massive, life-
threatening retroperitoneal bleeding. This space can hold
several liters of blood, making it a critical source of hidden
hemorrhage.
7. What is the recommended target for Systolic Blood
Pressure (SBP) in a trauma patient with an
uncontrolled hemorrhage prior to definitive surgical
control (Permissive Hypotension)? A. SBP > 120 mmHg
B. SBP 80–90 mmHg (or MAP 50–60 mmHg) C. SBP < 60
mmHg D. SBP > 140 mmHg Correct Answer: B Rationale:
Permissive hypotension aims to maintain enough perfusion to
vital organs without dislodging clots or exacerbating bleeding.
A SBP of 80–90 mmHg is generally targeted until hemorrhage
control is achieved.
8. Which of the following is a key component of
preventing Ventilator-Associated Pneumonia (VAP) in
trauma patients? A. Keeping the patient supine at all times
B. Daily sedation vacations and oral care with chlorhexidine C.
Routine changing of ventilator circuits every 24 hours D. Using
high tidal volumes (10–12 mL/kg) Correct Answer: B
Rationale: Daily sedation interruptions allow for assessment
of readiness to extubate, reducing ventilation time.
, Chlorhexidine oral care reduces bacterial load. High tidal
volumes increase lung injury risk.
9. A trauma patient develops oliguria (urine output <
0.5 mL/kg/hr) despite adequate fluid resuscitation.
What is the most likely cause? A. Primary renal failure B.
Pre-renal azotemia due to persistent hypovolemia or abdominal
compartment syndrome C. Post-renal obstruction from a
bladder stone D. Psychogenic polydipsia Correct Answer: B
Rationale: In the early post-resuscitation phase, oliguria is
most commonly pre-renal, caused by inadequate effective
circulating volume or increased intra-abdominal pressure
compromising renal blood flow.
10. Which imaging modality is considered the gold
standard for identifying blunt cerebrovascular injury
(BCVI) in high-risk trauma patients? A. Carotid Doppler
Ultrasound B. CT Angiography (CTA) of the neck C. MRI of the
brain D. Plain X-ray of the cervical spine Correct Answer: B
Rationale: CTA of the neck is highly sensitive and specific for
detecting dissections, pseudoaneurysms, and occlusions
associated with BCVI, especially in patients with cervical spine
fractures or Le Fort II/III facial fractures.
11. What is the primary pathophysiology behind
"Trauma-Induced Coagulopathy" (TIC)? A. Excessive
production of clotting factors B. Consumption of clotting
factors, platelets, and fibrinogen, combined with acidosis and
hypothermia C. Hyperactive platelet aggregation D. Increased
vitamin K absorption Correct Answer: B Rationale: TIC is
driven by the "lethal triad" of hypothermia, acidosis, and
coagulopathy. It involves the consumption of clotting factors
and platelets, as well as fibrinolysis, making standard lab tests
like PT/PTT potentially misleading.
12. When managing a patient with a spinal cord injury
at the T6 level or above, what is the primary concern
