TCRN Exam Review Question And
Answers 2025
Circumfrential burns - correct answers ✅✅Full-thickness burns
result in the formation of an eschar that is tough and unyielding.
Can cause a burn compartment syndrome, and often requires
escharotomy
Shock - correct answers ✅✅Systemic reaction to insult that
causes decreased oxygen delivery to the cells
4 Classifications of Shock - correct answers ✅✅1. Hypovolemic
2. Distributive
3. Cardiogenic
4. Obstruction
Hypovolemic Shock - correct answers ✅✅Low blood volume
results in altered perfusion (Ex: Hemorrhage, third spacing)
Distributive Shock - correct answers ✅✅Severe vasodilation with
normal blood volume results in altered perfusion (Ex: Sepsis,
anaphylaxis, neurogenic)
Cardiogenic Shock - correct answers ✅✅Altered cardiac function
results in reduced perfusion (Ex: Blunt chest injury, CHF)
,TCRN Exam Review Question And
Answers 2025
Obstructive Shock - correct answers ✅✅Blockage in the system
causes altered perfusion (Ex: PE, high PEEP, tension
pneumothorax)
Alpha Receptors - correct answers ✅✅Activated by sympathetic
nervous system, causing:
Vasoconstriction
Glycogenolysis
Diaphoresis
Glycogenolysis - correct answers ✅✅Breakdown of glucose
stores in the liver to provide increased circulating glucose,
stimulated by Alpha receptors
Beta 1 Receptors - correct answers ✅✅*Think: 1 heart
Cause increased heart rate and contractility
Beta 2 receptors - correct answers ✅✅*Think: 2 lungs
Cause bronchodilation and increased respiratory rate
RAAS System - correct answers ✅✅Increases resorption of
sodium and water in the kidneys to increase vascular volume,
decreasing urine output

Blood cultures before antibiotics
Broad spectrum antibiotics
30 ml/kg fluid bolus for hypotension
6 hr. Sepsis Bundle - correct answers ✅✅Repeat lactic
Start pressors if fluid bolus ineffective
Gain central access for pressors
Symptoms of Early Shock - correct answers ✅✅Normotensive
with NARROWING pulse pressure
Tachycardia
Weak and thready pulse
Tachypnea with DEEP respirations
Normal lactic
Cool and clammy
Anxiety, impending doom
Decreased urine output
Symptoms of Late Shock - correct answers ✅✅Hypotension
Tachycardia
Tachypnea with shallow respirations
Elevated lactic
Cool, clammy, and mottled skin
