- Q1What is the definition of shock?Lactic acid production due to anaerobic metabolismSystolic blood pressure < 65 mm HgMetabolic supply to tissues does not meet demandWhen you are scared of something30s
- Q2What are the two pathways that pyruvate can pyruvate take?Lactate production or gluconeogenesisKrebs cycle or Lactate productionKrebs cycle or gluconeogenesisLactate production or glycolysis30s
- Q3Why does shock have increased lactic acid production (besides anaerobic metabolism)?Epinephrine activation of alpha 2 receptorsDecreased clearance no increased productionAll of it is from anaerobic metabolism from tissue ischemiaEpinephrine activation of beta 2 receptors30s
- Q4How is lactate clearedIt is changed back into pyruvate to go into the Krebs cycleIt is metabolized by the brainCleared by kidneys and liverHoffman degradation30s
- Q5Cold shock is defined by…?Increased systemic vascular resistanceDecreased effective intravascular volumeVasoconstriction (both venous and arterial)Decreased or inadequate stroke volume30s
- Q6Warm shock is defined by… ?Increased preloadDecreased systemic vascular resistanceNarrow pulse pressureDecreased afterload30s
- Q7What are the components of stroke volume?Preload, afterload, and heart ratePreload, contractility, and systemic vascular resistanceAfterload and contractilityPreload, afterload and contractility30s
- Q8Which one does not cause a decrease in preload?HemorrhageVasodilationMyocarditisGI bleed30s
- Q9Which one does not cause a decrease in contractility?MyocarditisAortic StenosisCongenital heart diseaseCardiac ischemia30s
- Q10Which one does not cause increased afterload?Aortic StenosisLeft Ventricular outflow obstructionIncreased vasodilationHypertensive emergency30s
- Q11What correlates with systolic blood pressure?Peripheral Vascular ResistanceEnd diastolic volumeCardiac OutputStroke volume30s
- Q12What correlates with diastolic blood pressure?End diastolic volumePeripheral Vascular ResistanceCardiac OutputStroke volume30s
- Q13What is the first compensation for a decrease in stroke volume to maintain cardiac output?Increase peripheral vascular resistanceEpinephrineIncrease heart rateDecreased urine output30s
- Q1414. What is the next step if an increase in heart rate is inadequate to maintain cardiac output?Increase systemic vascular resistanceMore increased heart rateDecreased urine outputIncreased contractility30s
- Q15What is cold shock?Increase in afterloadDecrease in cardiac outputIncreased in systemic vascular resistance leading to bradycardiaDecrease in stroke volume leading to increased systemic vascular resistance30s
