Hypomagnesium vs Hypermagnesium ......ANSWER........hypo;
from malabsorption, associated with low Ca/K, neuromuscular
irritability, tetany, increased reflexes
hyper; from renal failure, skeletal muscle depression, muscle
weakness, respiratory depression, bradycardia
What is capillary hydrostatic pressure? ......ANSWER........(blood
pressure) facilitates the outward movement of water from the
capillary to the interstitial space
,age 2 of 56
What happens to the percentage of body water through the
lifespan? ......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? ......ANSWER........- increased adipose
tissue
- decreased muscle mass
- renal decline
- diminished thirst
,age 3 of 56
What is the definition of osmotic force? ......ANSWER........Amt. of
hydrostatic pressure required to oppose the osmotic movement
of water.
What is filtration? ......ANSWER........movement of fluid from the
capillary into the interstitial space
What is reabsorption? ......ANSWER........movement of fluid from
interstitial space into the capillary
What is capillary oncotic pressure? ......ANSWER........Water
pulling
attracts water from the interstitial space back into the capillary
osmotically
What is interstitial hydrostatic pressure? ......ANSWER........Water
pushing.
, age 4 of 56
facilitates the inward movement of water from the interstitial
space into the capillary
What is interstitial oncotic pressure? ......ANSWER........water
pulling
attracts water from the capillary into the interstitial space
osmotically.
What is Starlings hypothesis? ......ANSWER........Net filtration =
forces favoring filtration - forces opposing filtration
What forces favor filtration? ......ANSWER........1. Capillary
hydrostatic pressure (blood pressure)
