EPALS Updated 20 Actual Exam Question
and Answer | A+ Verified Updated |
Frequently Tested
• Hypovolemic schock -✓✓decreased circulating blood volume
(dehydration/trauma)
• distributive shock -✓✓inadequate disruption of blood, so that the blood flow is
insufficient for the oxygenation of the tissues. (anaphylaxis/sepsis/neurogenic)
• cardiogenic shock -✓✓circulatory failure due to poor heart function
(cardiomyopathy/myocarditis/cardiac surgery)
• obstructive shock -✓✓circulatory failure due to obstruction of blood flow to/from
the heart (tension pneumothorax/cardiac tamponade)
• Dissociative Shock -✓✓insufficient oxygen carrying capacity of the blood
(anaemia/carbon monoxide poisoning)
• Weight Estimation -✓✓weight (kg) = (age in years +4) x2
• cardiac output -✓✓Cardiac output = heart rate x stroke volume (blood volume
ejected each contraction)
• blood pressure -✓✓blood pressure = cardiac output X systemic vascular
resistance
• compensation mechanism in shock -✓✓Tachycardia, vasoconstriction, increased
myocardial contractibility
• Sizing of oropharyngeal airway -✓✓laid against the side of the face, has a length
equal to the distance between the level of the patients incisors (or where they will
be) to the angle of the jaw
• sizing nasopharyngeal airway -✓✓depth - from the nostril to the angle of the
mandible.
