Which of the following are causes of intrarenal acute kidney injury? (Select all that apply.)

Choice A rationale
A regular diet with no added salt may not be sufficient to address the fluid retention associated with acute glomerulonephritis and peripheral edema.

Choice B rationale
While a low-protein, low-potassium diet may be considered for certain kidney conditions, it does not specifically address the fluid and sodium management needed in acute glomerulonephritis with edema.

Choice C rationale
A low-carbohydrate, low-protein diet is not indicated in this scenario as it does not provide the necessary restrictions on sodium and fluid that are required for a child with edema and oliguria due to acute glomerulonephritis.

Choice D rationale
A low-sodium, fluid-restricted diet is most appropriate for a child with acute glomerulonephritis and peripheral edema. This diet helps manage the edema and prevent further fluid overload, which is crucial in the care of this condition.

Choice A rationale
Storing the medication at room temperature is a practical instruction but does not explain the therapeutic purpose of the medication, which is essential for patient understanding.

Choice B rationale
Epoetin alfa (Procrit) is used to treat anemia associated with chronic kidney disease by supplementing erythropoietin, a hormone the damaged kidneys can no longer produce effectively. This is the most informative statement for the patient's understanding of the medication's purpose.

Choice C rationale
While epoetin alfa can improve anemia and potentially improve quality of life, it does not directly delay the need for dialysis, which is determined by overall kidney function and not solely by the presence of anemia.

Choice D rationale
Epoetin alfa does not have a role in preventing AV fistula clotting. It is specifically used to stimulate red blood cell production and has no direct effect on clotting mechanisms.
