Section 1: Traumatic Hypovolaemia
Question 1
Which of the following best defines traumatic hypovolaemia in the context of prehospital
emergency care?
A. A condition resulting exclusively from external haemorrhage requiring immediate fluid
resuscitation
B. A complex condition often associated with polytrauma, requiring management focused on
locating and stopping the bleed, resuscitating the patient, and transferring care
C. A state of reduced circulating volume caused by dehydration and electrolyte imbalance
D. A transient hypotensive episode that resolves spontaneously with supine positioning
Answer: B
Explanation: Traumatic hypovolaemia is a complex condition frequently associated with
polytrauma. Its management requires a systematic approach focused on three key priorities:
locating and controlling the source of haemorrhage, resuscitating the patient to restore adequate
perfusion, and facilitating timely transfer to definitive care. This definition encompasses the
multifaceted nature of the condition and the comprehensive approach required for optimal patient
outcomes.
Question 2
The lethal triad associated with traumatic hypovolaemia consists of which three components?
A. Hypotension, bradycardia, and hyperglycaemia
B. Coagulopathy, acidosis, and hypothermia
C. Tachycardia, tachypnoea, and altered consciousness
,D. Anaemia, thrombocytopenia, and leukocytosis
Answer: B
Explanation: The lethal triad refers to the three interrelated pathophysiological disturbances that
compound morbidity and mortality in traumatic hypovolaemia: coagulopathy (impaired clotting),
acidosis (metabolic derangement from hypoperfusion), and hypothermia (loss of body heat).
These components create a vicious cycle where each exacerbates the others, significantly
increasing mortality risk if not addressed promptly.
Question 3
What is the recommended target systolic blood pressure for permissive hypotension in adults
without suspected traumatic brain injury?
A. 60 mmHg
B. Approximately 80 mmHg
C. 100 mmHg
D. 120 mmHg
Answer: B
Explanation: In adult patients without suspected traumatic brain injury, permissive hypotension
targets a systolic blood pressure of approximately 80 mmHg. This strategy balances the need for
adequate organ perfusion against the risk of exacerbating haemorrhage through aggressive fluid
resuscitation. By maintaining a lower blood pressure target, clot stability is preserved while still
providing sufficient perfusion to vital organs.
Question 4
In which of the following clinical scenarios is permissive hypotension absolutely
contraindicated?
A. Isolated extremity trauma in a normotensive patient
, B. Penetrating chest trauma with tachycardia
C. Pregnancy, suspected TBI, and paediatrics
D. Blunt abdominal trauma with suspected solid organ injury
Answer: C
Explanation: Permissive hypotension is contraindicated in pregnancy (due to the need for
adequate uteroplacental perfusion), suspected traumatic brain injury (to prevent secondary
ischaemic injury), and paediatric patients (who have limited physiological reserve). In these
populations, higher blood pressure targets are necessary to protect vulnerable organ systems and
ensure optimal outcomes.
Question 5
Which of the following conditions should be considered as an alternative cause of hypotension in
a trauma patient?
A. Hypovolaemic shock only
B. Obstructive shock, cardiac tamponade, cardiogenic shock, tension pneumothorax, and
spinal/neurogenic shock
C. Distributive shock from sepsis
D. Anaphylactic shock
Answer: B
Explanation: While hypovolaemia is the most common cause of hypotension in trauma,
clinicians must consider other aetiologies including obstructive shock (e.g., tension
pneumothorax, cardiac tamponade), cardiogenic shock (from myocardial contusion or
infarction), and spinal/neurogenic shock (from spinal cord injury). A comprehensive differential
diagnosis is essential to guide appropriate management and avoid potentially harmful
interventions.
