ch 34 Pathophysiology test 3
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 35-year-old client is diagnosed with acute kidney injury (AKI) and is started on hemodialysis. The client is concerned with the diagnosis and wants to know what to expect in the progression of this disorder. Which statement best addresses the client's concern?
"Acute kidney injury is abrupt in onset and often reversible if recognized early and treated appropriately."
With the increased risk of drug toxicity among chronically ill older adults, which statement by the nurse explains why the older adult's kidney is vulnerable to toxic injury?
"The kidney is rich in blood supply and can concentrate toxins in high levels in the medullary portion of the kidney."
The health care provider is comparing results of a client's recent GFR measurement. Which result would be interpreted as normal?
120 to 130 mL/minute
The nurse is caring for a client who has had acute blood loss from ruptured esophageal varices. What does the nurse recognize is an early sign of prerenal failure?
Baseline urine output of 50 mL/hr that is now 10 mL/hr
The nurse caring for four male clients recognizes which client is at highest risk for developing postrenal kidney failure?
Client with prostatic hyperplasia
A client asks, "Why did my provider order a glomerular filtration rate (GFR) to my usual blood work?" The nurse's best response is based on the fact that GFR can estimate serum levels of which substance?
Creatinine
A new client presents with elevated BUN, systemic edema, a BP of 145/93 mm Hg, recurrent infections, and a GFR of 51 mL/min/1.73 m2. Which treatment should the nurse anticipate?
Dialysis
Skeletal disorders frequently accompany chronic kidney disease (CKD). The nurse recognizes which statements regarding bone turnover in CKD are correct? Select all that apply.
In high bone turnover, there is both increased bone formation and increased resorption. High bone turnover produces porous, coarse-fibered bone. Metabolic acidosis of CKD can affect bone turnover. Both high and low turnover present risk for fracture.
A client is to receive a radiocontrast media as part of a diagnostic scan. Which intervention is intended to reduce the nephrotoxic effects of the radiocontrast media?
Increasing the normal saline intravenous infusion rate prior to the exam
10s Report this Question The client with substance use disorder was found unconscious after overdosing on heroin 2 days prior. Because of prolonged pressure on the muscles the client has developed myoglobinuria, causing which complication?
Obstruction of the renal tubules with myoglobin and damaged tubular cells
A client has experienced severe hemorrhage and is in prerenal failure. The nurse anticipates the client's blood urea nitrogen (BUN) and serum creatinine laboratory results will be in which range?
The BUN-to-creatinine ratio is 20:1.
A client with chronic kidney disease (CKD) will be managed with peritoneal dialysis. Which description of this type of dialysis is most accurate?
Treatment involves the introduction into the peritoneum of a sterile dialyzing solution, which is drained after a specified time.
A geriatric nurse is caring for several clients. Which alterations in health should the nurse attribute to age-related physiologic changes?
a loss of over half the client's normal kidney function.
The primary care provider for a newly admitted hospital client has added the glomerular filtration rate (GFR) to the blood work scheduled for this morning. The client's GFR results return as 50 mL/minute/1.73 m2. The nurse explains to the client that this result represents:
a loss of over half the client's normal kidney function.
