Renal Question #24
A client in the intensive care unit with acute kidney injury is found to have tall peaked T waves on the electrocardiogram (ECG). An order for administration of polystryrene sulfonate (Kayexalate) is ordered. The nurse will continue to monitor for which complication the client is experiencing?
- End stage renal failure.
Kidney damage that affects renal function will have a risk of hyperkalemia. Kidney injury causes retention of fluids and nitrogenous wastes, and as a result, the kidneys cannot regulate electrolytes. Potassium is often affected and ECG reveals peaked T waves with high potassium levels. Kayexalate will help move potassium out. The client will not have hypokalemia, may have hyperphasphatemia, hypermagnesium, and hypocalcemia. The other selections are the opposite findings. Kidney injury does not imply end stage renal failure.
