A patient with acute kidney injury and metabolic acidosis has a high potassium level. Besides Kayexalate, which intervention would directly address both the hyperkalemia and the acidosis?
- Restricting dietary potassium intake.
- Providing oral phosphate binders to reduce potassium absorption.
- Initiating sodium bicarbonate infusion. (correct)
- Administering a loop diuretic to increase potassium excretion.
A patient with acute kidney injury (AKI) develops metabolic acidosis. Which clinical manifestation would you expect to observe as the body attempts to compensate for this acid-base imbalance?
A patient with acute kidney injury (AKI) develops metabolic acidosis. Which clinical manifestation would you expect to observe as the body attempts to compensate for this acid-base imbalance?
- Kussmaul's respirations. (correct)
- Decreased heart rate.
- Slow, shallow respirations.
- Increased urine output.
A patient with acute kidney injury is receiving insulin to manage hyperkalemia. What potential risk should the nurse monitor for most closely during this treatment?
A patient with acute kidney injury is receiving insulin to manage hyperkalemia. What potential risk should the nurse monitor for most closely during this treatment?

Study Notes
- Acute kidney injury can lead to metabolic acidosis.
- Hyperkalemia can be treated with Kayexalate, monitor bowel movements to rule out constipation, and check electrolytes.
- Sodium bicarbonate can be administered to treat metabolic acidosis.
- Insulin can be administered, which pushes potassium back into the cell.
- Prerenal acute kidney injury can be caused by heart failure, low cardiac output, and dehydration.
- Intrarenal acute kidney injury can be caused by nephrotoxic drugs and ischemia.
- Postrenal acute kidney injury can be caused by urinary tract infections, benign prostatic hyperplasia, and neurogenic bladder.
- Risk factors include dehydration, vomiting, and hemorrhaging.
