The nurse is reviewing the health records of assigned clients. The nurse plans care knowing that which client is at risk for a potassium deficit? Answer Potassium-rich gastrointestinal (GI) fluids are lost through GI suction, which places the client at risk for hypokalemia. The client with intestinal obstruction, Addison's disease, and metabolic acidosis is at risk for hyperkalemia. A nurse reviews a client's electrolyte results and notes a potassium level of 5.5 mEq/L. The nurse understands that a potassium value at this level would be noted with which condition? Answer A serum potassium level that exceeds 5.1 mEq/L is indicative of hyperkalemia. Clients who experience the cellular shifting of potassium, as in the early stages of massive cell destruction (i.e., with trauma, burns, sepsis, or metabolic or respiratory acidosis), are at risk for hyperkalemia. The client with Cushing's syndrome or diarrhea and the client who has been overusing laxatives are at risk for hypokalemia. A nurse reviews a client's electrolyte results and notes that the potassium level is 5.4 mEq/L.
