1. A 45-year-old male presents to the emergency department following
a motor vehicle collision. He is tachycardic and hypotensive. Which of
the following is the priority intervention during the primary survey?
A) Obtain a detailed medical history.
B) Perform a head-to-toe assessment.
C) Identify and treat life-threatening conditions.
D) Order a complete blood count.
Answer: C) Identify and treat life-threatening conditions.
Explanation: The primary survey in trauma care is designed to identify
and immediately address life-threatening conditions following the
ABCDE (Airway, Breathing, Circulation, Disability, Exposure) framework.
Obtaining a detailed history, performing a full head-to-toe assessment,
and ordering labs are secondary or tertiary actions that should not
delay the identification and management of immediate threats to life.
2. A patient arrives with a penetrating injury to the chest. Which finding
is most indicative of a tension pneumothorax?
,2|Page
A) Decreased breath sounds on the affected side.
B) Hypotension and jugular venous distension.
C) Subcutaneous emphysema.
D) Tracheal deviation to the contralateral side.
Answer: D) Tracheal deviation to the contralateral side.
Explanation: Tracheal deviation away from the affected side is a late
but classic sign of tension pneumothorax, indicating significant
mediastinal shift. While decreased breath sounds, hypotension with
jugular venous distension (obstructive shock), and subcutaneous
emphysema may also be present, tracheal deviation is the most specific
and dramatic indicator of this life-threatening condition requiring
immediate needle decompression.
3. In the initial assessment of a trauma patient, which of the following is
considered the most reliable indicator of adequate tissue perfusion?
A) Heart rate.
B) Blood pressure.
C) Urine output.
D) Mental status.
Answer: D) Mental status.
Explanation: Mental status is a highly sensitive indicator of cerebral
perfusion and overall tissue oxygenation. A deteriorating level of
consciousness often signifies inadequate cerebral blood flow, which is

an early sign of hypoperfusion. While heart rate, blood pressure, and
urine output provide valuable information, they can be influenced by
various factors and may not reflect perfusion status as rapidly or
accurately as changes in mental status.
4. A patient is involved in a blast injury. The nurse suspects an
abdominal injury. Which of the following mechanisms is responsible for
primary blast injuries?
A) Impact with debris.
B) The blast wave itself.
C) The patient being thrown against a wall.
D) Inhaled toxic fumes.
Answer: B) The blast wave itself.
Explanation: Primary blast injuries are caused by the direct effect of the
blast wave (overpressurization) on the body, particularly affecting air-
filled organs like the lungs, ears, and gastrointestinal tract. Impact with
debris results in secondary injuries, being thrown against a wall causes
tertiary injuries, and inhaled toxic fumes are a component of quaternary
injuries.
5. A 30-year-old female arrives with a closed head injury and is actively
seizing. Which initial medication should be administered to manage the
seizure?
A) Lorazepam.
, 4|Page
B) Phenytoin.
C) Levetiracetam.
D) Valproic acid.
Answer: A) Lorazepam.
Explanation: Benzodiazepines, such as lorazepam, are the first-line
treatment for acute seizures in the emergency setting due to their rapid
onset and efficacy. Phenytoin, levetiracetam, and valproic acid are
second-line or maintenance agents that are not suitable for immediate
cessation of active seizure activity, as they take longer to achieve
therapeutic levels.
6. During the secondary survey, a patient is found to have a pelvic
fracture. Which of the following actions is crucial for managing this
injury?
A) Log roll the patient to assess the back.
B) Apply a pelvic binder.
C) Encourage early ambulation.
D) Perform a rectal examination.
Answer: B) Apply a pelvic binder.
Explanation: Pelvic fractures can lead to significant hemorrhage.
Applying a pelvic binder is a critical intervention to reduce pelvic
volume, stabilize the fracture, and help tamponade bleeding. Log rolling
can destabilize an unstable pelvic fracture and should be minimized.
