Nurb 3050 Final Exam Questions With 100%
Verified Answers
Edema - answer✔an excess of fluid in the interstitial compartment, which causes a swelling or
enlargement of tissues
Prolonged edema interferes with - answer✔venous return, arterial circulation, and cell function
Causes of edema - answer✔1. increased capillary hydrostatic pressure
2. decreased plasma osmotic pressure in the capillaries
3. lymphatic obstruction
4. increased capillary pearmeability
Increased Capillary Hydrostatic Pressure - answer✔-equivalent to higher blood pressure
-forces excessive fluid out of capillary into tissue
Hypervolemia - answer✔increased blood volume cause by kidney failure, pregnancy, and CHF
Decreased Plasma Osmotic Pressure in the Capillaries - answer✔-loss of plasma proteins
Lymphatic obstruction - answer✔- tumor or infection damages a lymph node or lymph node is
removed
, ©BRAINBARTER 2024/2025
-cannot circulate lymph fluid
Increased Capillary Permeability - answer✔- results from an inflammatory response, bacterial
toxins, burn or wound infections
Effects of Edema - answer✔-localized swelling
- redness or pale
-pain
-pitting edema
-weight gain
-headache
-functional impairment
-impaired arterial circulation
- susceptible to tissue breakdown
-high BP
Dehyrdration - answer✔insufficient body fluid resulting from either inadequate intake or
excessive loss of fluids, or a combination of both
-measured by change in weight
hypovolemia - answer✔loss of fluids in the vascular compartment (bloodstream)
Causes of dehydration - answer✔-vomiting and diarrhea
, ©BRAINBARTER 2024/2025
-excessive sweating
-GI suction
-DKA
-insufficient water intake
-use of concentrated formula for infants
diabetic ketoacidosis - answer✔insufficient insulin, leading to high blood glucose levels and
mobilization of lipids
effects of dehydration - answer✔dry mucous membrane
decreased skin turgor
Low BP, weak pulse
fatigue
increased hematocrit
decreasing mental function
confusion & loss of conciousness
turgor - answer✔elasticity
hematocrit - answer✔percentage of red blood cells in volume of blood
body compensated for dehydration by - answer✔increasing thirst
, ©BRAINBARTER 2024/2025
increasing heart rate
constricting cutaneous blood vessels
producing less urine
Third spacing - answer✔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 - answer✔-deficit of sodium
- caused by early chronic renal failure, sweating, vomiting and diarrhea, diuretics (fluid pills),
hormonal imbalances, excessive water intake
effects of hyponatremia - answer✔anorexia, nausea, cramps, fatigue, lethargy, muscle weakness,
headache, confusion, seizure, decreased BP, impaired nerve conduction, hypovolemia
hypernatremia - answer✔increased amount of sodium
-caused by large amount of sodium intake, insufficient ADH, loss of thirst, watery diarrhea,
prolonged periods of respiration
effects of hypernatremia - answer✔weakness, agitation, firm subcutaneous cells, increased thirst,
dry mouth, decreased urine output
Hypokalemia - answer✔deficient potassium levels
