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

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.

Question 3 of 5

Which of the following is a high-priority nursing diagnosis for both diabetic ketoacidosis and hyperosmolar hyperglycemic syndrome?

Correct Answer: B

Rationale: The correct answer is B: Fluid volume deficient. Both diabetic ketoacidosis and hyperosmolar hyperglycemic syndrome can lead to severe dehydration and electrolyte imbalances. Addressing fluid volume deficiency is crucial to stabilize the patient's condition. Choice A is not the priority as the main concern is the fluid imbalance, not activity intolerance. Hyperthermia (choice C) may be present but is not the primary concern compared to fluid volume deficit. Impaired nutrition (choice D) is not the immediate priority in these emergency situations. In summary, maintaining fluid balance is essential to manage both conditions effectively.

Question 4 of 5

Continuous venovenous hemodialysis is used to

Correct Answer: D

Rationale: The correct answer is D because continuous venovenous hemodiafiltration (CVVHDF) combines ultrafiltration, convection, and dialysis to maximize fluid and solute removal. Ultrafiltration removes plasma water, convection removes fluids and solutes, and dialysis facilitates solute removal through diffusion. Choice A is incorrect because convection alone does not remove solutes, but CVVHDF combines convection with other methods. Choice B is incorrect because CVVHDF is not specifically used for volume overload, although it does remove fluids. Choice C is incorrect because CVVHDF does not involve adding dialysate to remove solutes; instead, it relies on diffusion for solute removal. In summary, the correct answer D is the best choice as it encompasses all the components needed for comprehensive fluid and solute removal in CVVHDF.

Question 5 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.
