After providing discharge teaching, a nurse assesses the client's understanding regarding increased risk for metabolic alkalosis. Which statement indicates that the client needs additional teaching?

A. "I don't drink milk because it gives me gas and diarrhea.": Avoiding excessive milk intake does not contribute to metabolic alkalosis and is safe. Lactose intolerance or gastrointestinal discomfort is unrelated to the development of alkalosis, so this statement does not indicate a misunderstanding. B. "I take sodium bicarbonate after every meal to prevent heartburn.": Regular use of sodium bicarbonate, an alkaline antacid, can increase systemic bicarbonate levels, leading to metabolic alkalosis. This statement indicates a risk factor for alkalosis and demonstrates that the client may not understand the potential complications of chronic antacid use. C. "I have been taking digoxin every day for the last 15 years.": Long-term digoxin use is associated with potassium imbalance, but in itself does not directly cause metabolic alkalosis. The client’s understanding in this statement does not indicate increased risk for alkalosis and does not require correction. D. "In hot weather, I sweat so much that I drink six glasses of water each day.": Excessive sweating leads to loss of sodium, chloride, and potassium, which can contribute to metabolic alkalosis if not properly replaced. Drinking water alone does not exacerbate alkalosis risk significantly, so this statement does not demonstrate misunderstanding of alkalosis risk.
