An older patient comes into the clinic complaining of watery diarrhea for several days with abdominal and muscle cramping. The nurse realizes that this patient is demonstrating which imbalance?

Choice A: Client is currently prescribed spironolactone is incorrect because spironolactone is a potassium-sparing diuretic that can cause hyperkalemia, or high potassium level, not hypokalemia, or low potassium level. Spironolactone works by blocking the action of aldosterone, which is a hormone that regulates sodium and potassium balance in the body.

Choice B: Client reports drinking 3.5 to 4 L of water each day is incorrect because drinking excessive water can cause hyponatremia, or low sodium level, not hypokalemia. Hyponatremia occurs when the water intake exceeds the water output, diluting the sodium concentration in the blood.

Choice C: Client has an NG tube to gastric suction is correct because gastric suction can cause hypokalemia by removing gastric fluids that contain potassium. Gastric suction can also cause metabolic alkalosis, which is a condition where the blood pH is high and the HCO3 is high, indicating a loss of metabolic acids or an excess of bicarbonate in the body. Metabolic alkalosis can cause potassium to shift from the extracellular fluid to the intracellular fluid, thus lowering the serum potassium level.

Choice D: Client has a history of alcohol abuse disorder is incorrect because alcohol abuse can cause hypomagnesemia, or low magnesium level, not hypokalemia. Hypomagnesemia occurs when there is inadequate intake or excessive loss of magnesium, which is an essential mineral for many enzymatic reactions in the body.

Hypomagnesemia can impair the secretion and action of parathyroid hormone, which regulates calcium and phosphorus balance in the body.

Choice A Reason: This is correct because phosphorus is a mineral that is essential for bone health, energy metabolism, and acid-base balance. Hypophosphatemia is a low level of phosphorus in the blood, which can cause muscle weakness, bone pain, and confusion. The nurse should request a dietitian consult for selecting foods high in phosphorus, such as dairy products, meat, fish, eggs, nuts, and beans.

Choice B Reason: This is incorrect because poultry, peanuts, and seeds are foods that are high in phosphorus, not low. The nurse should not instruct the patient to avoid these foods, as they can help increase the serum phosphorus level and prevent further complications of hypophosphatemia.

Choice C Reason: This is incorrect because aluminum hydroxide antacids are medications that can lower the serum phosphorus level by binding to phosphorus in the gastrointestinal tract and preventing its absorption. The nurse should not provide aluminum hydroxide antacids as prescribed, as they can worsen the patient's condition and cause aluminum toxicity. The nurse should consult with the provider about alternative medications for treating stomach ulcers that do not affect phosphorus levels.

Choice D Reason: This is incorrect because sodium phosphate is a medication that can raise the serum phosphorus level by providing supplemental phosphorus. The nurse should not instruct the patient to avoid the intake of sodium phosphate, as it can help correct hypophosphatemia and restore normal phosphorus balance. The nurse should administer sodium phosphate as ordered and monitor the patient's serum phosphorus level and renal function.
