Ch. 34 Acute Kidney Injury and Chronic Kidney Disease

A client with a diagnosis of end-stage renal disease received a kidney transplant 2 years ago that was deemed a success. During the most recent follow-up appointment, the nurse should prioritize the client for referral based on which statement?

Impaired platelet function

A client with a history of chronic kidney disease (CKD) is experiencing increasing fatigue, lethargy, and activity intolerance. The care team has established that the client's glomerular filtration rate (GFR) remains at a low, but stable, level. Which laboratory assessments will most likely be prescirbed to help determine the cause of these new symptoms?

Blood work for hemoglobin, red blood cells, and hematocrit

A client sustained acute tubular injury approximately 2 hours ago. Which cause of acute kidney injury (AKI) would the nurse suspect the client is experiencing?

Intrarenal

Vitamin D metabolism is deranged in clients with chronic kidney disease (CKD). The nurse recognizes that which statement regarding vitamin D is correct?

Kidneys convert inactive vitamin D to its active form, calcitriol.

The GFR is considered to be the best measure of renal function. What is used to estimate the GFR?

Serum creatinine

An 86-year-old female client has been admitted to the hospital for the treatment of dehydration and hyponatremia after she curtailed her fluid intake to minimize urinary incontinence. The client's admitting laboratory results are suggestive of prerenal failure. The nurse should be assessing this client for which early sign of prerenal injury?

Sharp decrease in urine output

A client has undergone a kidney transplant and voices concerns about organ rejection to the nurse. The most appropriate response by the nurse would be:

"You will be given medication to decrease the likelihood of your immune system attacking your new kidney."

A client is suspected to have renal disease. The nurse would suggest which diagnostic determinations to confirm this diagnosis? Select all that apply.

- Urinary sediment of red and white cells - Ultrasonography - Measurement of cystatin C - Imaging studies

Accumulation of nitrogenous wastes such as urea in the circulatory system is an early sigh of chronic kidney disease (CKD). The nurse knows that normal levels of urea in blood are approximately:

20 mg/dL (7.14 mmol/L)

A client has prerenal failure. The nurse knows that this type of failure is characterized by which relationship of blood urea nitrogen (BUN) to serum creatinine levels?

A BUN to creatinine level ratio of 20:1
