Cards

Term
Functions of the kidney
Definition
1. Elimination of metabolic wastes
2. Blood pressure regulation
3. Erythrocyte production
4. Vitamin D activation
5. Acid-base balance
Term
Kidneys role with vitamin D?
Definition
converts vitamin D from food to an active form for use by the body
Term
How do kidneys help maintain acid base balance
Definition
they secrete H ions into the tubules and reabsorbs bicarb from the tubules
Term
Functions of Vitamin D
Definition
-Obtained in diet or UV radiation
-Has to be activated in liver and 2nd step in kidney proces
-Helps with absorption of Ca and decreased Ca is replaced with fibrous tissue
-Depends on cholesterol in the blood.
Term
What triggers the release of renin
Definition
1. decreased renal perfusion
2. extracellular fluid
3. serum Na concentrations
4. increased urinary concentrations
Term
Post volume residual urine
Definition
normal is <50ml
a strait catheterization or ultrasound is performed after a person has voided to determine amount of urine left in bladder.
Term
Purposes of renal biopsy
Definition
1. diagnose disorders that affect kidney and tubules
2. Assess coagulation status prior to a procedure
Term
Upper Urinary Tract Infection
Definition
-Affects renal parenchyma, pelvis, and ureters
-CM: fever, chills, flank pain
-Pyelonephritis
Term
Lower tract urinary infection
Definition
-lower urinary tract
-no systemic manifestations
-cystitis
Term
Complicated UTI
Definition
obstruction, stones, catheters
have DM or neurologic disorders
Term
UTI can be caused by an alteration in defense mechanisms by:
Definition
1. Complete emptying of the bladder
2. Ureterovesical junction competence
3. Peristaltic activity in ureters
4. ph<6
5. Abundant glycoproteins
Term
Causes of nephrotic syndrome
Definition
-primary glomular disease
