endocrine Flashcards
how does ADH influence the kidneys
causes it to reabsorb water
how does aldosterone influence the kidneys
increases Na absorption
how does ANP influence the kidneys
Decreases Na absorption and increases H20 excretion
ANP MAKES YOU PEE
what is renin
- hormone produced by kidney
- raises BP by vasoconstriction
serum creatinine
- 5-1.2 mg/dL
- impaired renal function is the only thing that elevates this
- 60% of renal function is lost before this # even elevates
BUN
10-20 mg/dL
- byproduct of protein breakdown
- indicates liver or renal impairment
24 hr creatinine clearance urinalysis
good indicator of renal function
-how well is the protein being cleared in the blood
changes to renal function with CKD
cant filter blood so fluid & electrolytes are retained
- fluid overload
- increased K
- decreased Ca (low activated VitD)
- metabolic acidosis (kidneys cant absorb HCO3 or excrete H)
-overall decline
CKD on acid/base
- metabolic acidosis
- cant excrete H
- cant reabsorb HCO3
- kussmal breathing
CKD on fluids/electrolytes
10-20% increase in ECF
- risk for fluid overload
- hyponatremia early
- hypernatremia & hyperkalemia later
- hypocalcemia
CKD on renal system
nephrons larger/work harder
- work sufficiently until 80% function lost
- kidneys shrivel
- BUN increases
- UO decreases & concentration increases
CKD on cardiac
fluid overload
- HTN (lack of RAAS)
- peripheral edema
- uremia (urine in blood)
- CHF
- atherosclerosis
CKD on respiratory
pulmonary edema
- pleuritis
- metabolic acidosis
- crackles/SOB/low SPO2
CKD on hematological
bleeding/bruising
- platelets in toxic environment
- uremia
- anemia (low RBC)
- low EPO production
- Low RBC survival time
*can give EPO injection if super super low
CKD on GI
anorexia (no appetite)
- taste uremia bc vascular mouth
- build up of ammonia in GI tract
- ulcers bc no prostaglandins
- GI bleeds
- malnutrition
