A 6-year-old child is brought to the trauma bay after a motor vehicle
collision. The child is pale, anxious, tachycardic, and has cool
extremities. Blood pressure is currently normal. Which finding most
strongly suggests compensated shock?
A. Bradycardia with warm extremities
B. Tachycardia with delayed capillary refill
C. Hypertension with bounding pulses
D. Isolated fever with normal perfusion
Answer: B. Tachycardia with delayed capillary refill
Rationale: In children, tachycardia and peripheral vasoconstriction
commonly develop before hypotension. A child may maintain blood
pressure through compensatory mechanisms despite significant blood
loss. Delayed capillary refill, cool skin, and weak peripheral pulses are
important early indicators of compensated shock.
Which mechanism allows a child to maintain systolic blood pressure
during the early stages of hemorrhagic shock?
A. Increased vagal tone
B. Peripheral vasodilation
,C. Increased systemic vascular resistance
D. Reduced myocardial contractility
Answer: C. Increased systemic vascular resistance
Rationale: Pediatric patients can compensate for reduced circulating
volume through tachycardia, increased vascular tone, and
redistribution of blood toward vital organs. Consequently, hypotension
is often a late and ominous sign of pediatric shock.
A 4-year-old trauma patient has tachycardia, cool extremities, delayed
capillary refill, and weak peripheral pulses. Which intervention should
occur early?
A. Wait for hypotension before treating
B. Begin appropriate vascular access and resuscitation
C. Administer a diuretic
D. Restrict oxygen administration
Answer: B. Begin appropriate vascular access and resuscitation
Rationale: Pediatric shock should be recognized and treated based on
perfusion abnormalities rather than waiting for hypotension. Early
vascular access and appropriate resuscitation are essential because
children may deteriorate rapidly after compensatory mechanisms fail.
What is the most appropriate initial fluid strategy for a child with
traumatic hypovolemic shock when blood products are not immediately
available?
A. Small-volume hypotonic fluid only
B. Isotonic crystalloid in an appropriate bolus with reassessment
C. Oral water administration
D. Dextrose-containing maintenance fluid as the primary resuscitation
fluid
,Answer: B. Isotonic crystalloid in an appropriate bolus with
reassessment
Rationale: Isotonic crystalloid can be used initially when blood
products are unavailable, with the child's response reassessed
frequently. In significant traumatic hemorrhage, however, blood
products are preferred when available, and excessive crystalloid
administration should be avoided.
Which finding is most concerning for progression from compensated to
decompensated shock in a child?
A. Mild anxiety
B. Normal mental status
C. Development of hypotension
D. Slight tachycardia
Answer: C. Development of hypotension
Rationale: Pediatric patients can preserve blood pressure despite
substantial circulatory compromise. Once hypotension develops,
compensatory mechanisms are failing and shock is generally
advanced. This requires immediate aggressive evaluation and
treatment.
Which vital-sign abnormality is particularly useful for recognizing early
pediatric shock?
A. Tachycardia
B. Isolated hypertension
C. Bradycardia in every child
D. Mild hypothermia alone
Answer: A. Tachycardia
, Rationale: Tachycardia is one of the earliest physiologic responses to
reduced circulating volume in children. It must be interpreted in
context because pain, fear, hypoxia, medications, and other factors can
also increase heart rate.
A 2-year-old with blunt abdominal trauma has increasing tachycardia
and delayed capillary refill. Blood pressure remains normal. What is the
best interpretation?
A. Shock is excluded because blood pressure is normal
B. The child may have compensated hemorrhagic shock
C. The child has neurogenic shock by definition
D. No reassessment is necessary
Answer: B. The child may have compensated hemorrhagic shock
Rationale: Normal blood pressure does not exclude serious pediatric
hemorrhage. Children can maintain systolic pressure through
vasoconstriction and increased heart rate until circulating volume loss
becomes severe.
Which clinical feature most directly reflects inadequate tissue perfusion?
A. Normal temperature
B. Delayed capillary refill
C. Mild rhinorrhea
D. Normal pupil size
Answer: B. Delayed capillary refill
Rationale: Delayed capillary refill can indicate peripheral
hypoperfusion, especially when accompanied by cool skin, weak
pulses, altered mental status, and reduced urine output. It should not
be interpreted in isolation.
