What happens to the percentage of body water through the lifespan? - CORRECT
ANSWER Newborns; 75-90%
Childhood; 60-65%
Adults; 60%
Older adults; declines with age
Why do older adults experience a decrease in body percentage of water? -
CORRECT ANSWER - increased adipose tissue
- decreased muscle mass
- renal decline
- diminished thirst
What is the definition of osmotic force? - CORRECT ANSWER Amt. of hydrostatic
pressure required to oppose the osmotic movement of water.
What is filtration? - CORRECT ANSWER movement of fluid from the capillary
into the interstitial space
,What is reabsorption? - CORRECT ANSWER movement of fluid from interstitial
space into the capillary
What is capillary hydrostatic pressure? - CORRECT ANSWER (blood pressure)
facilitates the outward movement of water from the capillary to the interstitial
space
What is capillary oncotic pressure? - CORRECT ANSWER Water pulling
attracts water from the interstitial space back into the capillary osmotically
What is interstitial hydrostatic pressure? - CORRECT ANSWER Water pushing.
facilitates the inward movement of water from the interstitial space into the
capillary
What is interstitial oncotic pressure? - CORRECT ANSWER water pulling
attracts water from the capillary into the interstitial space osmotically.
What is Starlings hypothesis? - CORRECT ANSWER Net filtration = forces
favoring filtration - forces opposing filtration
What forces favor filtration? - CORRECT ANSWER 1. Capillary hydrostatic
pressure (blood pressure)
2. interstitial oncotic pressure (water pulling)
, What forces oppose filtration? - CORRECT ANSWER 1. Plasma (capillary) oncotic
pressure (water pulling)
2. Interstitial hydrostatic pressure
What is the major force of filtration and reabosoprtion? - CORRECT ANSWER
capillary pressures
What happens at the arteriole end of the capillary in terms of fluid forces? -
CORRECT ANSWER hydrostatic pressure > interstitial oncotic pressure = water
into the insterstitial space
FILTRATION
What happens at the venous end of a capillary in terms of fluid forces? - CORRECT
ANSWER capillary oncotic pressure > interstitial hydrostatic pressure = fluid back
into ciruclation
REABSORPTION
What is the pathophysiology of edema? - CORRECT ANSWER increased in forces
favoring fluid filtration from the capillaries or lymphatic channels into the tissues
What is the primary ECF cation? - CORRECT ANSWER Sodium
What is the primary ECF anion? - CORRECT ANSWER Chloride
