TOPIC 2 Midterm Flashcards
assessment of patient urine at one point in time
Snapshot
valuable screening tool for urinary tract infections, kidneys diseases, and other conditions
Urinalysis
to know how much urine the body is producing in a day or how much of a particular substance is eliminated in a day
24 urine collection
diagnostic exam uses sound waves to create images of the kidney(s)
Renal ultrasound
refers to a series of X-rays taken of the kidneys, their collecting or drainage system (the ureters), and the bladder
Serum studies intravenous pyelography
syndrome in which glomerular filtration declines abruptly from hours to days and is usually reversible.
Acute renal failure
Main causes of acute renal failure
• Not enough blood flow to the kidneys
▪ Direct damage to the kidneys
▪ Urine backed up in the kidneys
condition involving a decrease in the kidneys’ ability to filter waste and fluid from the blood.
Chronic renal failure
referred to as fluid replacement
Fluid resuscitation
administered to improve cardiac and tissue oxygenation, which in part depends on flow
Fluid resuscitation
Two classes of intravenous solutions
Crystalloids, colloids
solutions of electrolytes in water that cross freely from the vascular space into the interstitium
Crystalloids
contain large molecules that cannot permeate healthy capillary membranes
Colloids
recommended as “first-line” for fluid resuscitation in such common critical illnesses as sepsis, hemorrhagic shock, and cardiac arrest.
Colloids
lining of patient own belly acts as a natural filter
Peritoneal dialysis
Wastes are taken out by means of a cleansing fluid
Dialysate
