Quote from feels like jd
after trolling through a bunch of study guides i guess myabe i'm just dense. in one guide it mentions that dehydration is specifically a lack of fluid specifically intracellular. however in another one and in my text it mentions dehydration in more of a symptomatic context. any help? thanks.
knowing principles of medical terminology would be very helpful here. i would recommend that as you do your reading you keep a medical dictionary at your side and refer to it frequently to explain these differences that seem confusing.
is a condition that occurs when there has been excessive loss of body fluid. the nursing diagnosis for this is deficient fluid volume
de - from, withouthypovolemia
hydra - water
tion - state of being
literally, a state of being without water
refers to decreased fluid volume of the blood
hypo - under, beneath, below, lowsymptom,
vol(umen) - volume
emia - blood
literally, blood volume that is low
from greek symptoma
which means occurrence; anything that has befallen someone; casualty. any perceptible change in the body or its functions that indicates disease or the kind or phases of disease. symptoms may be classified as objective, subjective, cardinal, and sometimes, constitutional. (taber's cyclopedic medical dictionary
sym - with, together with, along, beside
tom (from the greek verb piptein) - to fall
the loss of body fluids occurs first. as it continues the hypovolemia happens. some of the symptoms of dehydration are decreased urine output; increased urine concentration; weakness; sudden weight loss (except in third-spacing); decreased venous filling; increased body temperature; decreased pulse volume/pressure; change in mental state; elevated hematocrit
; decreased skin/tongue turgor; dry skin/mucous membranes; thirst; increased pulse rate; decreased blood pressure. elevated hematocrit is a symptom of the hypovolemia that is going on.
dehydration can also be part of a cascade of events of other medical conditions going on particularly if there are imbalances in the electrolytes or hormones that control fluids. for example, if a patient is developing type i diabetes, one of their presenting symptoms may be dehydration due to the attempt of their kidneys to dump the excess glucose from their body via the renal system.
