5 Complications and Integrated Practice Online Quiz Questions

True or false: A high BUN or creatinine value alone establishes that a patient with acute kidney injury needs dialysis.

A patient has had several days of vomiting and diarrhea, has low urine output and blood pressure below their usual level, and has a rising creatinine. Their lungs are clear and they have no peripheral edema. Which broad cause of acute kidney injury is most likely?

What urine-output rate, in mL/kg/hour, is commonly used as the threshold for oliguria?

A patient with acute kidney injury and worsening fluid retention is being assessed for pulmonary edema. Select all findings that support concern that fluid is affecting the lungs.

True or false: A normal ECG rules out hyperkalemia in a patient with acute kidney injury.

During hemodialysis, a patient becomes dizzy as their blood pressure falls. What is the name of this complication?

A patient receives hemodialysis through a fistula or graft. Which findings at or related to the vascular access require prompt attention? Select all that apply.

A patient with acute kidney injury has a low bicarbonate level and a low blood pH. Which acid–base disturbance do these findings indicate?

A patient with acute kidney injury develops worsening breathlessness, low oxygen saturation, crackles, and edema despite initial medical management. Which situation most directly supports considering kidney replacement therapy?

After an intervention for acute kidney injury, which monitoring plan best assesses the patient’s response?

A patient with worsening kidney failure develops new confusion and chest pain. Explain why these symptoms are concerning, what the immediate response should be, and how kidney replacement therapy may factor into the plan.

Which listed condition is an example of kidney tissue injury that can cause acute kidney injury?

A patient with acute kidney injury has had several days of vomiting and diarrhea, low blood pressure, and low urine output, but clear lungs and no edema. Which approach to fluid management is most appropriate?

Which electrolyte can rise when kidney excretion is impaired and may cause dangerous conduction abnormalities?

Which laboratory pattern is consistent with metabolic acidosis in a patient with impaired kidney function?

Which serious uremic complication is listed alongside encephalopathy and bleeding tendency?

A patient with acute kidney injury has rising BUN and creatinine but no identified life-threatening fluid, electrolyte, or acid–base problem and no significant uremic complication. Which principle should guide the dialysis decision?

A patient develops acute kidney injury after exposure to a potentially nephrotoxic medication. This exposure is a possible cause of kidney tissue injury.
