MULTIPLE CHOICE

1. An elderly patient is in a motor vehicle accident and incurs a significant internal hemorrhage. He is at greatest risk for which category of acute kidney injury (AKI)?

ANS:   C

Any condition that decreases blood flow, blood pressure (BP), or kidney perfusion before arterial blood reaches the renal artery that supplies the kidney may be anatomically described as prerenal AKI. When arterial hypoperfusion due to low cardiac output, hemorrhage, vasodilation, thrombosis, or other cause reduces the blood flow to the kidney, glomerular filtration decreases and consequently urine output decreases.

3. Which of the following intravenous solutions has been found to expedite renal recovery?

ANS:   B

Although the choice of fluid and the amount infused are based on the patient’s general condition and the patient’s ability to tolerate intervention, normal saline or “solute loading” in the prevention mode of treating pre-acute tubular necrosis has been found to expedite recovery.

4. The nurse is caring for a patient with acute kidney injury. Upon assessing the patient’s electrocardiogram the nurse notes peaked T-waves and a widening of the QRS interval. The nurse knows these are signs of:

ANS:   D

Specific electrocardiographic changes are associated with hyperkalemia: peaked T-waves, a widening of the QRS interval, and ultimately, ventricular tachycardia or fibrillation.

5. Which of the following nursing interventions is used in caring for the patient with acute kidney injury (AKI)?

ANS:   C

Anemia is an expected side effect of kidney failure that occurs because the kidney no longer produces the hormone erythropoietin. Irritation of the gastrointestinal tract from metabolic waste accumulation is expected, and stress ulcer prophylaxis must be prescribed. Stool, nasogastric drainage, and emesis are routinely tested for occult blood.
