NSG 460 Shock and GI Video (Complete And Verified Study material) (8pages) LEARNEXAMS

1. What three components are needed for ADEQUATE cellular perfusion?: Answer 1) CIRCULATION 2) CO 3) Vasomotor tone 2. Shock can be defined as inadequate delivery of _____________ to ____________ Answer Oxygen;To the cells (inadequate tissue perfusion) 3. What are normal ranges for MAP?: Answer MAP should be 70 - 100 A MAP 60+ is essential for adequate perfusion. 4. Why is anaerobic metabolism considered inefficient?: Answer - Only a fraction of regular energy is being produced in anaerobic metabolism (~ 1/18) - Anaerobic metabolism = lactic acid production = lactic acidosis = metabolic acidosis 5. How can shock be an issue with FLUIDS?: Answer Hypovolemic shock! - The most common cause of shock - R/t inadequate circulating blood volume,fluid shiftsto interstitialspace (burn shock) - Causes: GI bleeds, dehydration, etc. 6. What are some of the interstitial spaces that fluid can shift to?:
