a classic sign of kidney dysfunction?
- Costovertebral angle (CVA) pain - hematuria : blood in the urine, - proteinuria : protein in the urine.
what is the kidney dysfunction ?
1) Decreased perfusion of the kidneys activates the renin-angiotensin-aldosterone system, abbreviated RAAS, increasing sodium and water retention and potentially leading to hypertension. 2) As the kidneys produce erythropoietin to increase red blood cells, failing kidneys cause lower than normal red blood cell levels. 3)synthesize vitamin D, which helps absorb calcium. -Hypocalcemia may develop in kidney failure.
a measurement of urine concentration = dehydration
1) Glucose in the urine most commonly results from hyperglycemia, and may indicate diabetes. 2) Diabetic ketoacidosis may cause ketones to appear in the urine. 3)Proteins in the urine can result from intense exercise, after which minimal levels may appear, and from glomerulonephritis, which may lead to more significant levels. 4)Blood in the urine may indicate damage to structures of the renal system. 5)The presence of bilirubin and urobilinogen may indicate liver damage, 6) the presence of nitrite and leukocyte esterase normally indicate infection of the renal system.
Kidney dysfunction may become so compromised that dialysis may be required. Two forms of dialysis may be used :
1) peritoneal dialysis : a patient's peritoneum is filled with fluid to be exchanged 2) hemodialysis : blood is drawn from the body, run through a dialyzer, and then returned to the body. -Both methods seek to carry out the kidney's function of filtering the blood.
Patients at risk for renal dysfunction include ;
1) taking nephrotoxic medications, 2)recent streptococcal infections, 3)patients suffering from diabetes mellitus and/or 4)hypertension, and patients with major surgery.

Albumin levels are normal. Albumin levels are increased. Glomerular filtration rate (GFR) must be reduced. Albumin levels are decreased, due to loss in urine. Albumin levels are unaffected by renal function; thus, this value is not helpful.
Albumin levels are decreased, due to loss in urine.

Choose the classification for each type of renal dysfunction. Erythropoietin levels in kidney failure INCREASED UNCHANGED DECREASED
DECREASED Kidneys produce erythropoietin. When kidney damage or failure occurs, synthesis of erythropoietin is compromised.
Why are BUN and Cr levels higher than normal in George? Disruption of the buffering system Muscle breakdown is increasing serum levels of these factors Decreased GFR Antibody attack of the glomeruli have increased secretion of these substances
Decreased GFR George's BUN and Cr are increasing because normally these substances are filtered by the kidney and partially removed from the blood. When GFR decreases, these factors increase in the blood.
Which of the following may explain George's anemia? Select all that apply. Decreased erythropoietin Not enough protein intake Anemia commonly accompanies heart failure Lack of intrinsic factor Glomerular damage
Decreased erythropoietin Glomerular damage The kidneys produce erythropoietin to maintain red blood cells levels. If the kidneys are damaged, erythropoietin levels may fall. Intrinsic factor is found in the stomach and is not altered by kidney failure. Finally, if the glomeruli are damaged, red blood cells may be filtered into the urine, leading to hematuria.
Which of the following is a cause of prerenal failure? Nephrotoxic medications Streptococcal infection Decreased perfusion Ureter obstruction
Decreased perfusion
In George's condition, why is GFR lower than normal? Decreased perfusion of the kidney Elevated pressure due to hydronephrosis Blockage of the glomerular membrane by antibodies Cyst formation within the kidneys
Decreased perfusion of the kidney George's heart failure likely makes maintaining adequate perfusion of body tissues difficult. As perfusion of the kidneys declines, so does the GFR.
Why is oliguria occurring in George? Nephron cell necrosis Decreased renal perfusion and GFR Increased BUN and Cr are blocking renal filtration Cyst formation due to genetic disease is blocking renal blood flow
Decreased renal perfusion and GFR George is experiencing oliguria for the same reason BUN and Cr levels are elevating: the kidneys are not adequately perfused. Urine is only formed when the blood is filtered. If insufficient blood is available for filtration, urine formation decreases.
A renal patient presents with edema. What may be the primary cause of this edema? Urinary stone causing backup Decreased serum albumin due to renal loss. Increased gluconeogenesis by the kidney Decreased erythropoietin synthesis
Decreased serum albumin due to renal loss.

ELEVATED LEUKOCYTE ESTERASE The presence of leukocyte esterase in urinalysis can indicate urinary tract infection. Elevated ketones may indicate the presence of diabetic ketoacidosis. Cr stands for creatinine, a waste product that should be present in urine.
Why does George experience disorientation as a result of renal failure? Elevated toxin levels in the blood Anemia Hyperkalemia Elevated urine output by the kidney
Elevated toxin levels in the blood Encephalopathy may develop with acute or chronic renal failure when toxins buildup in the blood. These toxins begin to compromise brain function.
A patient with chronic renal failure reports that he is feeling like his skin is "itching." What is an appropriate response by the nurse?

Nitrite Leukocyte esterase Glucose
Choose the classification for each type of renal dysfunction. Shock PRERENAL INTRARENAL POSTRENAL
PRERENAL Shock can result from a number of causes. With this condition, inadequate perfusion of organs and tissues occurs, including the kidneys. As the problem involves delivery of blood to the kidneys, it is a prerenal condition.
What type of edema is George likely to experience with renal failure? Pulmonary edema Periorbital edema Dependent edema Localized edema in feet
Periorbital edema Edema manifests in a number of ways in the body, but a particular form of edema, periorbital edema, may signify renal failure. The swelling around the eyes often develops with increased fluid accumulation.

Positive immunoglobulin results.
George, age 72, recently suffered a heart attack, damaging his left ventricle. He appears to be suffering from left-sided heart failure. Stroke volume, blood pressure, and cardiac output are all reduced. George's renal function may be impaired. Serum blood urea nitrogen (BUN) and creatinine (Cr) levels are increasing and glomerular filtration rate (GFR) is significantly reduced. Oliguria is present, as is edema of the face and extremities. George seems to be becoming more confused and disoriented. Further blood laboratory values reveal hypocalcemia, hyperkalemia, and anemia. Based on the information provided, which type of renal dysfunction is most likely in George's case: prerenal, intrarenal, or postrenal? Prerenal Intrarenal Postrenal None. Based on available data, George's renal function appears normal.
Prerenal The most likely renal failure type is prerenal. Prerenal failure occurs when the kidneys are not adequately perfused. In George's case, his heart failure is likely resulting in reduced blood flow to the kidneys. The increasing levels of BUN and Cr, along with decreasing GFR, shows George's kidneys are not functioning normally
