Nurb 3050 final Questions and Correct
Answers | Latest Update
Edema

 an excess of fluid in the interstitial compartment, which causes a swelling

or enlargement of tissues



Prolonged edema interferes with

 venous return, arterial circulation, and cell function



Causes of edema

 1. increased capillary hydrostatic pressure

 2. decreased plasma osmotic pressure in the capillaries

 3. lymphatic obstruction

 4. increased capillary pearmeability



Increased Capillary Hydrostatic Pressure

 -equivalent to higher blood pressure

-forces excessive fluid out of capillary into tissue



Hypervolemia

 increased blood volume cause by kidney failure, pregnancy, and CHF



Decreased Plasma Osmotic Pressure in the Capillaries

 -loss of plasma proteins

Lymphatic obstruction

 - tumor or infection damages a lymph node or lymph node is removed

-cannot circulate lymph fluid



Increased Capillary Permeability

 - results from an inflammatory response, bacterial toxins, burn or wound

infections



Effects of Edema

 -localized swelling

- redness or pale

-pain

-pitting edema

-weight gain

-headache

-functional impairment

-impaired arterial circulation

- susceptible to tissue breakdown

-high BP



Dehyrdration

 insufficient body fluid resulting from either inadequate intake or excessive

loss of fluids, or a combination of both

-measured by change in weight

hypovolemia

 loss of fluids in the vascular compartment (bloodstream)



Causes of dehydration

 -vomiting and diarrhea

-excessive sweating

-GI suction

-DKA

-insufficient water intake

-use of concentrated formula for infants



diabetic ketoacidosis

 insufficient insulin, leading to high blood glucose levels and mobilization

of lipids



effects of dehydration

 dry mucous membrane

decreased skin turgor

Low BP, weak pulse

fatigue

increased hematocrit

decreasing mental function

confusion & loss of conciousness



turgor

 elasticity



hematocrit

 percentage of red blood cells in volume of blood



body compensated for dehydration by

 increasing thirst

increasing heart rate

constricting cutaneous blood vessels

producing less urine



Third spacing

 fluids shifting out of the body into a body cavity or tissue where it is no

longer available as circulating fluid

- shift causes a fluid deficit in vascular compartment (hypovolemia) and fluid excess in the

interstitial space



Hyponatremia

 -deficit of sodium

- caused by early chronic renal failure, sweating, vomiting and diarrhea, diuretics (fluid pills),

hormonal imbalances, excessive water intake



effects of hyponatremia

 anorexia, nausea, cramps, fatigue, lethargy, muscle weakness, headache,

confusion, seizure, decreased BP, impaired nerve conduction, hypovolemia
