GU system Flashcards
Bones and kidneys explain
Kidneys form vit d which inhibits PTH and stimulates GI to keep ca+
How so kidneys help blood and when does this happen?
They make erythropoietin it is stimulated from hypoxia or lack of blood flow to kidneys
Kidneys and acid base balance
Secretes acids and reabsorbs bicarb
What is normal GFR and how much leaves?
125ml/min 1ml/min
GFR happens because of what type of pressure?
Hydrostatic blood pressure
Kidney disease will cause what left in kidneys 2
platelets and proteins
RASS system
Renin(Kidneys)-angeotensin 1- Ace(lungs) Angi 2(Vasoconstriction)- Aldosterone (adrenals)
What would cause RASS 3
Decrease profusion, bp or Na+
Where does acid/base balance take place?
Distal tube
S/S of metabolic acidosis 8
HA, Decreased blood pressure, hyperK+, mm twitching, Warm flushed skin, N/V/D, Changes in LOC, kussmaul.
Causes of Metabolic acidosis 4
DKA, severe diarrhea, renal fail, shock
Metabolic Alkalosis S/S 8
Restlessness, lethargy, Dysrhythmias (tachy) Hypoventilation, Confusion, N/V/D, mm-tremors, cramps, tingling, hypoK+
Metabolic Alkalosis causes 4
Severe vomiting, GI suctioning, diuretics, too much bicar.
Nephrotoxic drugs 6
End in cin or in sulfamides, silicyilins, gold heavy metals, lithium sporins, nitrosoureas (NSAIDS)
Anuria
olugaria
<100ml no urine
100-400ml in 24 hours
Urea vs creatinine
Urea end product of protein metabolism Creatinine nitrogen waste from muscle loss
What is BUN what is normal
Decreased urea from kidneys increases blood
6-20mg/dl
Normal creatinine level
0.6-1.3mg/dl
What is urine Creatinine clearance and what does it estimate?
24 hour test GFR
IVP? contraindication for?
Intravenous pyelogram, kidney disease.
KUB?
Kidneys, ureters, bladder, x ray with no contrast
Renal angiography? contrast?
Renal vasculature no contrast
Ct Contrast?
Can go either way
proximal con tube uses and filtrates
ATP glucose, Na+ amino acids, sm H20
Descending and ascending loop of henle
H20 Na+, K+ cl-
Distal con tube absorption what acts on it?
ca+, Na+ some H2o bicarb Aldosterone and ADH
Excretion in DCT
K+and ammonia
Collecting ducts and what acts on it
Acid/Base balance and ADH
