Urinary System Flashcards
Dysuria
Pain when urinating
What should the nurse do if urine dipstick test shows protein in urine?
Ask what meds patient takes, medication can affect testing.
Nephron
Functional unit of the kidney
GFR
Amount of blood filtered per minute by the kidneys ( normal is 125 mL/ min)
Costovertebral angle (cva)
Landmark useful in locating kidneys- formed by rib cage and vertebral column.
Anuria
Urine output < 100 mL per 24 hrs.
Basically no urine
Enuresis
Involuntary nocturnal urination
Oliguria
Scant urine
100-400mL per day
Polyuria
Large amount of urine in a given time
Why is acetazolazide given?
To alkalize urine
Why is mannitol given?
To decrease intracranial pressure
( for cerebral edema)
2 side effects of furosemide Lasix- loop diuretic
Remember works on loop of Henley ( loops lose calcium!)
Ototoxicity ( ringing ears)
Hypokalemia
Will remove calcium, chloride ect.
Hydrochlorothiazide
Works on distal convoluted tubule.
Calcium SPARING
Triamterene
Potassium SPARING. Gets rid of sodium
Spironolactone
Potassium sparing. Could cause hyperkalemia.
S/E gynocomastia
Arythmia.
Causes of kidney damage?
Acute:
dehydration
Hypovolemia
Chronic:
Diabetes
Renal artery stenosis
Acute renal failure- cause of prerenal?
Poor renal perfusion
Hypovolemia
Injury
Dehydration
Heart failure
A renal stone in the pelvis of the kidney will alter the function of the kidneys by interfering with
The collection and drainage of urine from the kidney
Intrarenal
Direct damage
Pyelonephritis
Infections
Nephrotoxic medications
Direct injury
Post renal
Urinary obstruction
BPH
Renal stone
Stricture
( anything that causes stasis)
Renal failure
Retain waste products
Sodium
Potassium
What happens in chronic kidney disease
Malaise Hypertension Proteinuria Hyperkalemia -arrhythmia Mineral and bone disorders Neuropathy Metabolic acidosis Severe uremia- pruritis , CNS depression Edema Oliguria
A patient with kidney disease has oliguria and a creatinine clearance 40 ML per minute. These findings most directly reflect abnormal function of
Glomerular filtration
The nurse identifies a risk for urinary calculi in a patient who relates a past history that includes
Hyperparathyroidism
Diminished ability to concentrate urine, associated with aging of the urinary system, is attributed to
Decreased function of the loop of Henley and tubules
During the physical assessment of the urinary system the nurse
Auscultated over each CVA to detect impaired renal bloodflow
