What is the priority nursing diagnosis with your patient diagnosed with end-stage renal disease?
A. Activity intolerance
B. Fluid volume excess
C. Knowledge deficit
D. Pain
B.
Fluid volume excess because the kidneys aren't removing fluid and wastes. The other diagnoses may apply, but they don't take priority.
Which finding leads you to suspect acute glomerulonephritis in your 32 y.o. patient?
A. Dysuria, frequency, and urgency
B. Back pain, nausea, and vomiting
C. Hypertension, oliguria, and fatigue
D. Fever, chills, and right upper quadrant pain radiating to
C.
Mild to moderate HTN may result from sodium or water retention and inappropriate renin release from the kidneys. Oliguria and fatigue also may be seen. Other signs are proteinuria and azotemia.
Which patient is at greatest risk for developing a urinary tract infection (UTI)?
A. 35 y.o. woman with a fractured wrist
B. 20 y.o. woman with asthma
C. 50 y.o. postmenopausal woman
D. 28 y.o. with angina
C.
Women are more prone to UTI's after menopause due to reduced estrogen levels. Reduced estrogen levels lead to reduced levels of vaginal Lactobacilli bacteria, which protect against infection. Angina, asthma and fractures don't increase the risk of UTI.
The most common early sign of kidney disease is:
A. Sodium retention
B. Elevated BUN level
C. Development of metabolic acidosis
D. Inability to dilute or concentrate urine
B.
Increased BUN is usually an early indicator of decreased renal function.
A patient with diabetes mellitus and renal failure begins hemodialysis. Which diet is best on days between dialysis treatments?
A. Low-protein diet with unlimited amounts of water
B. Low-protein diet with a prescribed amount of water
C. No protein in the
B.
The patient should follow a low-protein diet with a prescribed amount of water. The patient requires some protein to meet metabolic needs. Salt substitutes shouldn't be used without a doctor's order because it may contain potassium, which could make th
Your patient has complaints of severe right-sided flank pain, nausea, vomiting and restlessness. He appears slightly pale and is diaphoretic. Vital signs are BP 140/90 mmHg, Pulse 118 beats/min., respirations 33 breaths/minute, and temperature, 98.0F. Whi
D.
Patients with renal calculi commonly have blood in the urine caused by the stone's passage through the urinary tract. The urine appears dark, tests positive for blood, and is typically scant.
Which of the following causes the majority of UTI's in hospitalized patients?
A. Lack of fluid intake
B. Inadequate perineal care
C. Invasive procedures
D. Immunosuppression
C.
Invasive procedures such as catheterization can introduce bacteria into the urinary tract. A lack of fluid intake could cause concentration of urine, but wouldn't necessarily cause infection.
A patient diagnosed with sepsis from a UTI is being discharged. What do you plan to include in her discharge teaching?
A. Take cool baths
B. Avoid tampon use
C. Avoid sexual activity
D. Drink 8 to 10 eight-oz glasses of water daily
D.
Drinking 2-3L of water daily inhibits bacterial growth in the bladder and helps flush the bacteria from the bladder. The patient should be instructed to void after sexual activity.
Which intervention do you plan to include with a patient who has renal calculi?
A. Maintain bed rest
B. Increase dietary purines
C. Restrict fluids
D. Strain all urine
D.
All urine should be strained through gauze or a urine strainer to catch stones that are passed. The stones are then analyzed for composition. Ambulation may help the movement of the stone down the urinary tract. Encourage fluid to help flush the stones
A patient with diabetes has had many renal calculi over the past 20 years and now has chronic renal failure. Which substance must be reduced in this patient's diet?
A. Carbohydrates
B. Fats
C. Protein
D. Vitamin C
C.
Because of damage to the nephrons, the kidney can't excrete all the metabolic wastes of protein, so this patient's protein intake must be restricted. A higher intake of carbs, fats, and vitamin supplements is needed to ensure the growth and maintenance
You have a paraplegic patient with renal calculi. Which factor contributes to the development of calculi?
A. Increased calcium loss from the bones
B. Decreased kidney function
C. Decreased calcium intake
D. High fluid intake
A.
Bones lose calcium when a patient can no longer bear weight. The calcium lost from bones form calculi, a concentration of mineral salts also known as a stone, in the renal system.
A 22 y.o. patient with diabetic nephropathy says, "I have two kidneys and I'm still young. If I stick to my insulin schedule, I don't have to worry about kidney damage, right?" Which of the following statements is the best response?
A. "You have little to
D.
Kidney damage is still a concern. Microvascular changes occur in both of the patient's kidneys as a complication of the diabetes. Diabetic nephropathy is the leading cause of end-stage renal disease. The kidneys continue to produce urine until the end
What is the most important nursing diagnosis for a patient in end-stage renal disease?
A. Risk for injury
B. Fluid volume excess
C. Altered nutrition: less than body requirements
D. Activity intolerance
B.
Kidneys are unable to rid the body of excess fluids which results in fluid volume excess during ESRD.
Which of the following symptoms do you expect to see in a patient diagnosed with acute pyelonephritis?
A. Jaundice and flank pain
B. Costovertebral angle tenderness and chills
C. Burning sensation on urination
D. Polyuria and nocturia
B.
Costovertebral angle tenderness, flank pain, and chills are symptoms of acute pyelonephritis. Jaundice indicates gallbladder or liver obstruction. A burning sensation on urination is a sign of lower urinary tract infection.
Clinical manifestations of acute glomerulonephritis include which of the following?
A. Chills and flank pain
B. Oliguria and generalized edema
C. Hematuria and proteinuria
D. Dysuria and hypotension
C.
Hematuria and proteinuria indicate acute glomerulonephritis. These finding result from increased permeability of the glomerular membrane due to the antigen-antibody reaction. Generalized edema is seen most often in nephrosis.
Which drug is indicated for pain related to acute renal calculi?
A. Narcotic analgesics
B. Nonsteroidal anti-inflammatory drugs (NSAIDS)
C. Muscle relaxants
D. Salicylates
A.
Narcotic analgesics are usually needed to relieve the severe pain of renal calculi. Muscle relaxants are typically used to treat skeletal muscle spasms. NSAIDS and salicylates are used for their anti-inflammatory and antipyretic properties and to treat
A 30 y.o. female patient is undergoing hemodialysis with an internal arteriovenous fistula in place. What do you do to prevent complications associated with this device?
A. Insert I.V. lines above the fistula.
B. Avoid taking blood pressures in the arm wi
B.
Don't take blood pressure readings in the arm with the fistula because the compression could damage the fistula. IV lines shouldn't be inserted in the arm used for hemodialysis. Palpate pulses below the fistula. Lack of bruit or thrill should be report
An 18 y.o. student is admitted with dark urine, fever, and flank pain and is diagnosed with acute glomerulonephritis. Which would most likely be in this student's health history?
A. Renal calculi
B. Renal trauma
C. Recent sore throat
D. Family history of
C.
The most common form of acute glomerulonephritis is caused by group A beta-hemolytic streptococcal infection elsewhere in the body.
What change indicates recovery in a patient with nephrotic syndrome?
A. Disappearance of protein from the urine
B. Decrease in blood pressure to normal
C. Increase in serum lipid levels
D. Gain in body weight
A.
With nephrotic syndrome, the glomerular basement membrane of the kidney becomes more porous, leading to loss of protein in the urine. As the patient recovers, less protein is found in the urine.
Your 60 y.o. patient with pyelonephritis and possible septicemia has had five UTIs over the past two years. She is fatigued from lack of sleep, has lost weight, and urinates frequently even in the night. Her labs show: sodium, 154 mEq/L; osmolarity 340 mO
B.
Which cause of hypertension is the most common in acute renal failure?
A. Pulmonary edema
B. Hypervolemia
C. Hypovolemia
D. Anemia
B.
Acute renal failure causes hypervolemia as a result of overexpansion of extracellular fluid and plasma volume with the hypersecretion of renin. Therefore, hypervolemia causes hypertension.

- If prerenal failure goes on too long, can become intrarenal failure b/c tubules are dead (tubular necrosis)
Intrarenal
- Kidneys themselves are diseased or dead
Lupus
- Autoimmune disease that attacks small blood vessels (loves to attack kidneys)
- primarily affects females (15-45 y/o)
- Cause of death is usually kidney failure ("lupus nephritis")
