NU545 CHAPTER 3 EXAM QUESTIONS AND ANSWERS

WITH COMPLETE SOLUTIONS VERIFIED GRADED A++

they store less fat, higher metabolism rates, greater evaporative loss due to a larger body surface area

proportion to total body size


why are infants susceptible to significant tbw loss?


75%-80%


infants total body water percentage?


bc fat is hydrophobic and very little water is contained in adipose cells


why are obese people at greater risk for dehydration?


individuals with more body fat


what individuals have less total body water?


increased fat, decreased muscle, and reduced ability to regulate sodium and water


what causes total body water to decline with age?


starvation or malnutrition


what causes lowered plasma albumin?


lowered levels of plasma albumin cause fluid to move into the interstitials space


how does low plasma albumin cause edema?

, edema


the excessive accumulation of fluid within the interstitial spaces


albumin is, bc it has the highest concentration


what plasma protein is primarily responsible for plasma oncotic pressure?


increased capillary hydrostatic pressure, decreased plasma oncotic pressure, increased capillary

membrane permeability, lymphatic obstruction


what are the 4 mechanisms of edema?


increased capillary hydrostatic pressure


can result from venous obstruction or sodium/water retention, which increased the pressure behind the

obstruction pushing fluid from the capillaries into the interstitial spaces


decreased plasma oncotic pressure


results from loss or diminished production of plasma albumin, causing decreased oncotic attraction of

fluid within the capillary, with the fluid then moving in the interstitial spaces


increased capillary membrane permeability


associated with inflammation and the immune response, which are due to traumas, such as burn or

crush injuries, neoplastic disease, allergic reactions, infections


lymphatic obstruction


occurs when lymphatic channels are blocked because of infection of tumor, causing proteins and fluids

not to be reabsorbed and accumulate in interstitial space aka lymphedema
