During the diuretic phase of acute kidney injury, the nurse understands that the client is at risk for which of the following electrolyte imbalances?
Hyperkalemia and hypernatremia
Hypokalemia and hypernatremia
Hyperkalemia and hyponatremia
Hypokalemia and hyponatremia
The Correct Answer is D
A. Hyperkalemia and hypernatremia are generally not associated with the diuretic phase of AKI. In the diuretic phase, the primary issue is excessive loss of electrolytes and fluid, rather than their accumulation.
B. Hypokalemia can occur during the diuretic phase because diuretics increase the excretion of potassium along with water. Hypernatremia is not typical of the diuretic phase. Instead, sodium levels might decrease or remain normal due to the loss of fluid and electrolytes.
C. Hyperkalemia is unlikely during the diuretic phase as diuretics often lead to increased potassium loss. Hyponatremia is a more likely outcome during the diuretic phase due to the loss of sodium and fluid through increased urine output.
D. During the diuretic phase of AKI, there is significant loss of electrolytes, including potassium and sodium. Diuretics increase urine output, leading to the loss of potassium and sodium, which can occur as a result of excessive fluid and electrolyte loss.

Correct Answer is A
Explanation
A. This is an inflammation of the peritoneum, the lining of the abdominal cavity. It's a common complication of peritoneal dialysis (PD). Symptoms include nausea, vomiting, diarrhea, abdominal pain, and fever. Fluid discharge from the catheter site and an increased white blood cell count are also indicative of infection, supporting the diagnosis of peritonitis.
B. This is inflammation of the pericardium, the sac surrounding the heart. Symptoms typically include chest pain, shortness of breath, and irregular heartbeat.
C. This is inflammation of the pleura, the membranes surrounding the lungs. Symptoms include chest pain, shortness of breath, and dry cough.
D. This would present with severe abdominal pain, hypotension, and signs of shock. Nausea, vomiting, and diarrhea are not typical symptoms.
Correct Answer is C
Explanation
A. This is a common symptom of uremia, which is the buildup of waste products in the blood due to kidney failure. It is expected in a patient with ESRD who has discontinued dialysis.
B. As the body accumulates waste products, fatigue and lethargy are common symptoms of uremia. This is expected in a patient with ESRD who has discontinued dialysis.
C. Polyuria is excessive urination. With kidney failure, the kidneys are unable to concentrate urine, leading to oliguria or anuria, not polyuria. Therefore, polyuria would not be expected in this patient.
D. This is a white, crystalline deposit on the skin caused by the accumulation of urea and uric acid. It is a sign of severe uremia and would be expected in a patient with ESRD who has discontinued dialysis.
