question

Which patient is most prone to the development of pyelonephritis? A patient with:

answer

urinary reflux. Feedback: When a bacterial, fungal, or viral infection is present in the urinary tract, urinary retention and reflux increase the risk of the infection ascending the ureter to the kidneys, resulting in pyelonephritis.

question

Which of the following complications associated with renal failure should cause the nurse to notify the primary care provider of the need for immediate dialysis?

answer

Hyperkalemia Feedback: Hyperkalemia from decreased renal excretion of potassium can cause dysrhythmias and cardiac arrest and is the most pressing factor in the decision to dialyze.

question

A major modifiable risk factor for the development of renal calculi in the general population is:

answer

dehydration. Feedback: A major modifiable risk factor for the development of renal calculi in the general population is dehydration, since most renal calculi form when salts in the urine become concentrated or "supersaturated."

question

Renal calculi can be formed from:

question

A consequence of an upper urinary tract obstruction is:

answer

hydronephrosis. Feedback: Dilation of the urinary tract occurs proximal to the obstruction. In this case the proximal renal pelvis and kidney would enlarge, causing a condition known as hydronephrosis.

question

A patient has acute renal failure. What is another term the nurse can use to describe this condition?

answer

Acute kidney injury Feedback: The term "acute kidney injury" is preferred to the term "acute renal failure" because it captures the spectrum of this syndrome, which ranges from minimal or subtle changes in renal function to complete renal failure requiring renal replacement therapy.

question

answer

Hematuria after a GI viral infection Feedback: The disease manifests with gross or microscopic (30% to 40%) hematuria 24 to 48 hours after an upper respiratory tract or gastrointestinal mucosal viral infection.

question

Which microorganism will the nurse most likely observe on the report of a patient who has developed a urinary tract infection (UTI)?

answer

Escherichia coli

question

A patient with nephrotic syndrome asks the nurse what causes the edema. How should the nurse respond? The edema results from:

answer

loss of plasma proteins in the urine. Feedback: Glomerular membrane damage in nephrotic syndrome results in the loss of plasma proteins in the urine. Loss of albumin causes a decrease in plasma oncotic pressure that favors fluid movement from the capillaries into the tissues, resulting in edema.

question

A patient has nephrotic syndrome. Which laboratory result will the nurse monitor?

answer

Hyperlipidemia Feedback: Many clinical manifestations of nephrotic syndrome are related to loss of serum proteins and associated sodium retention, including edema, hyperlipidemia, lipiduria, vitamin D deficiency, and hypothyroidism.

question

If a patient's right kidney becomes blocked/obstructed, what should the nurse suspect will happen in the patient's left kidney?

answer

Obligatory and compensatory growth Feedback: The contralateral kidney must undergo obligatory and compensatory growth in order to compensate for the loss of function in the obstructed kidney.

question

The nurse is reading the patient's history. Which of the following will help confirm the diagnosis of overactive bladder?

answer

Nocturia Feedback: Overactive bladder is defined by the International Continence Society as a symptom syndrome of urgency, with or without urge incontinence, and usually associated with frequency and nocturia.

question

A patient has chronic pyelonephritis. What does the nurse suspect occurred in the patient's body?

answer

Kidney scarring Feedback: Chronic pyelonephritis is a persistent or recurrent infection of the kidney leading to scarring of one or both kidneys.

question

Which of the following terms will the nurse use to describe bladder dysfunction caused by a neurological disorder?

answer

Neurogenic bladder Feedback: A condition in which neurologic lesions cause bladder dysfunction is called neurogenic bladder.

question

A urologist is describing a procedure that uses ultrasound waves to break large renal calculi into smaller stones that can be passed through the urinary tract. Which procedure is the urologist discussing?

answer

Lithotripsy Feedback: Lithotripsy is a noninvasive way to treat kidney stones with ultrasound waves.

question

For a patient with chronic renal failure, which of the following hormones often needs to be therapeutically replaced?

answer

Erythropoietin Feedback: Since the kidneys are the sites of production of erythropoietin, this hormone often needs to be replaced in individuals with chronic renal failure to prevent anemia.
