Which finding on physical exam is MOST consistent with early (Class I) hemorrhagic shock?
Answer: Anxiety, normal BP, pulse less than 100 bpm
Class I hemorrhagic shock (less than 15% blood loss) presents with minimal changes: slight anxiety, normal BP, and HR under 100 bpm.
A post-cardiac arrest patient is being transported. Which target MAP should be maintained to optimize cerebral perfusion per post-ROSC care guidelines?
Answer: ≥65 mmHg
Post-ROSC guidelines recommend maintaining MAP ≥65 mmHg to optimize systemic and cerebral perfusion pressure during transport.
A patient in cardiogenic shock has cool extremities, pulmonary edema, and a BP of 78/50 mmHg. Which combination of interventions is most appropriate?
Answer: Vasopressor support, judicious fluid bolus if hypovolemic component, and consider inotrope
Cardiogenic shock management centers on vasopressors (norepinephrine or dopamine) to restore perfusion pressure, with inotropes (dobutamine) to improve cardiac output, while avoiding excessive fluid.
Which lab value is the most sensitive indicator of inadequate tissue perfusion and guides resuscitation efficacy in shock?
Answer: Serum lactate
Serum lactate is the most sensitive and widely used marker of tissue hypoperfusion; elevated levels indicate anaerobic metabolism from inadequate oxygen delivery.
An anaphylactic patient remains hypotensive after 2 doses of IM epinephrine and 2L IV fluid. What is the next pharmacological intervention?
Answer: Epinephrine IV infusion at 0.1-0.5 mcg/kg/min
Refractory anaphylactic shock unresponsive to IM epinephrine requires IV epinephrine infusion for continuous vasopressor and bronchodilatory support.
When performing resuscitative thoracotomy in the field for traumatic arrest, which patient has the best chance of neurologically intact survival?
Answer: Penetrating thoracic trauma with witnessed loss of vital signs within 15 minutes
EDT has the highest survival for penetrating thoracic wounds with witnessed cardiac arrest or vital signs lost within 15 minutes of arrival.
