NR 507 Week 2 Quiz Study Guide

Chamberlain College NR-507-Advanced Pathophysiology Study Guide Quiz 2-Week 2 1. Question Fluid & Electrolytes Differentiate between normal the balance movement of water & solutes between ICF & ECF = isovolemia . regulation of water balance- hypothalamic , pituitary, adrenal cortical , renal , cardiac, gastrointestinal regulation, insensible water loss. Abnormal cellular- changes in solute levels of ICF & ECF, Hypovolemia- ECF has lower osmolality than ICF which draws water INTO the cell causing cellular swelling & plasma volume decrease. Immune structure Function – body fluids functional compartments ICF (%40 of body weight) & ECF (%20 body weight) moving by osmosis. Intrvascular (IV) – blood plasma (<5 %), interstitial fluid (IF) fluid between the cells & outside blood vessels ( <15 % , other fluids lymph, synovial, CSF, intestinal, sweat, urine, intraocular, & body cavity fluids= 3 spaces ALL fluids in the body are called TBW, body temp regulation, lubrication (synovium, pleura & pericardium Fluids – normal, contracted & exp&ed Electrolytes- isotonic, hypertonic & hypotonic Values of electrolytes Sodium- 135-145 Potassium 3.5 -5 Chloride 106-106 Calcium 9-11 Bun 10-20 creatine 0.7- 1.2 Co2 (bicarb) 22-26 Magnesium 1.5-2.5 2. Question Fluid & Electrolytes Dehydration The excretion of ketone bodies results in loss of water & electrolytes Explore age-specific- Loss of fluids from diarrhea can represent a significant proportion of body weight in infants. Renal mechanisms that regulate fluid & electrolyte conservation may not be mature enough to counter the losses, so dehydration can develop rapidly.
