module 1 Flashcards
FVE hypervolemia
too much fluid in the vascular space causes: HF RF Too much sodium
hormonal regulation of fluid volume aldosterone
made in the adrenal glands and retains sodium and water which increases fluid volume. mineralsteriods
Too much aldosterone
CONN syndrome -hyperaldosteronism
Cushings
Not enough aldosterone
Addisons disease
hormonal regulation of fluid volume ADH
retains water
anti-diuretic hormone
too much ADH
FVE
SIADH
*ADH- think health problems
too little ADH
FVD
DI
*think shock
vasopressin
desmopression
ADH replacement
causes fluid retention
used for DI, enuresis
FVE s/s
distended neck veins edema VS changes: increase CVP, increase BP polyuria lung sounds wet
FVE tx
diuretic- hydrochlorothiasize, K sparing
decrease NA
bed rest
IV slowly to elderly pt
fluid retention
think heart first
FVD = hypovolemia
causes: loss of fluid from anywhere such as vomiting, diarrhea, bleeding
polyuria
third space- burns, ascites
FVD s/s
weight loss, decrease skin turgor, dry membranes
decreased uo
VS: D BP, I PULSE, I RR, D CVP
Urine specific gravity: increase
FVD tx
prevent further loss
replace fluids: mild deficit= oral; severe deficit= IV
monitor for overload
fall precautions
IV fluids isotonic
goes in and stays
D5W, 0.9 NS, LR, 55 1/4 NS
FOR: fluid loss when they dont have HTN, kidney or heart problems
NOT FOR: HTN, cardiac or kidney problems because it can cause hypernatremia, FVE, HTN
IV hypotonic
goes into the vascular space then moves OUT to rehydrate
D2.5W, 1/2 NS, 0.33 NS
FOR: clients with HTN, cardiac or kidney problems but need fluid replacement. immunocompromised patient
Will dilute in hypernatremia; good for dehydrated pt
Watch for cellular edema, FVD, Decrease BP
ph
Normal: 7.35 – 7.45 < 7.35 = Acidosis > 7.45 = Alkalosis Affects the brain Kidneys & Lungs control pH Lungs with CO2 = fast Kidneys with H+, HCO3 =slow
burns home safety
Hot h2o heaters table clothes ovens attached to walls cooking pots electrical socket
burn patho
tissue damage - plasma seeps (3rd spacing) - FVD/shock - increase pulse - decrease UO - epi and aldosterone compensate
too much ADH
retain water FVE SIADH worried about HF UO = concentrated blood= dilute
not enough ADH
losing water - SHOCK FVD DI UO = diluted blood = concentrated
concentrated makes the numbers go
UP
urine specific gravy, sodium, and hematocrit
problems with ADH think
head injury
basic solution given with blood
ns
IV hypertonic
enters the vessels and expands the vascular space
D10W, 3% NS, 5% NS, D5LR, TPN, ALBUMIN
FOR: hyponatremia, severe edema, burns, or ascites
watch: FVE, BP, PULSE
hypermagnesium
causes: renal failure anatacids s/s: warm, flushing tx: calcium gluconate, dialysis
hypercalcemia
causes: too much PTH thiazides (retain ca) immobilizations s/s: brittle bones, kidney stones tx: MOVE, fluids, add phos to diet,
s/s hyper magnesium and calcemia
D DTR weak muscle tone arrhythmia YES D LOC D pulse D RR
