Question 1 of 5

The most common cause of acute kidney injury in critically ill patients is

Correct Answer: A

Rationale: The correct answer is A: sepsis. Sepsis is a leading cause of acute kidney injury in critically ill patients due to the systemic inflammatory response leading to kidney damage. Fluid overload (B) can contribute but is not the primary cause. Medications (C) and hemodynamic instability (D) can also lead to acute kidney injury but are not as common as sepsis in critically ill patients.

Question 2 of 5

Which of the following patients is at the greatest risk of developing acute kidney injury? A patient who

Correct Answer: C

Rationale: The correct answer is C because the patient was recently discharged after a prolonged course of aminoglycoside therapy, which is a known risk factor for acute kidney injury due to its nephrotoxic effects. Choice A is incorrect because although aminoglycosides can cause kidney injury, the duration of therapy is shorter in this case. Choice B is incorrect because controlled hypertension is not a significant risk factor for acute kidney injury. Choice D is incorrect because fluid overload from heart failure may lead to other complications but is not directly associated with acute kidney injury.

Question 3 of 5

In determining the glomerular filtration rate (GFR) or creatinine clearance, a 24-hour urine is obtained. If a reliable 24-hour urine collection is not possible,

Correct Answer: D

Rationale: The correct answer is D because if a reliable 24-hour urine collection is not possible, a standardized formula can be used to estimate the GFR. This is typically done using the patient's serum creatinine level, age, sex, and race. It is a validated method when direct measurement is not feasible. A: Incorrect. It is still possible to estimate GFR using formulas when 24-hour urine collection is not possible. B: Incorrect. BUN alone is not sufficient to accurately determine renal function. C: Incorrect. BUN/Creatinine ratio is not a direct measure of GFR and may be influenced by other factors.

Question 4 of 5

The patient is complaining of severe flank pain when he tries to urinate. His urinalysis shows sediment and crystals along with a few bacteria. Using this information along with the clinical picture, the nurse realizes that the patient’s condition is

Correct Answer: C

Rationale: The correct answer is C: intrarenal. The presence of sediment, crystals, and bacteria in the urinalysis indicates an issue within the kidneys themselves. The flank pain suggests renal involvement. Prerenal would involve issues before the kidneys, such as inadequate blood flow. Postrenal would involve issues after the kidneys, such as urinary tract obstruction. Not renal related is incorrect as the symptoms and urinalysis findings clearly point to a renal issue.

Question 5 of 5

The patient is admitted to the unit with the diagnosis of rhabdomyolysis. The patient is started on intravenous (IV) fluids and IV mannitol. What action by the nurse is best?

Correct Answer: B

Rationale: The correct answer is B: Assess the patient's lungs. In rhabdomyolysis, muscle breakdown releases myoglobin which can cause kidney damage. Mannitol is given to prevent kidney damage by promoting diuresis. However, mannitol can also cause fluid overload and pulmonary edema. Therefore, assessing the patient's lungs is crucial to monitor for signs of fluid overload and prevent complications. A: Assessing the patient's hearing is not directly related to the management of rhabdomyolysis and mannitol administration. C: Decreasing IV fluids after administering a diuretic like mannitol can lead to inadequate fluid resuscitation and worsening kidney injury. D: Giving extra doses before radiological contrast agents is not necessary in the context of rhabdomyolysis and mannitol administration.
