150+ QUESTIONS WITH CORRRECT VERIFIED
ANSWERS |PRE-EVALUATED A+
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 reabsoption? - 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 circulation
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
Describe the relationship btw. Chloride and sodium and bicarbonate - CORRECT ANSWER-Cl follow
sodium and varies inversely with bicarb.
What hormone regulates sodium? where is it synthesized? - CORRECT ANSWER-Aldosterone.
Synthesized in the adrenal cortex.
When is aldosterone secreted? - CORRECT ANSWER-Decreased renal perfusion, low NA levels, high K
levels.
