Which statement best evaluates the effect of consuming several alcoholic drinks on short-term fluid balance?

• A. Alcohol consumption stimulates thirst reflexes and ADH simultaneously, guaranteeing that any increased urine output is immediately compensated by higher fluid intake without net fluid imbalance
• B. Alcohol acts as an ADH analog that enhances renal water reabsorption and therefore prevents dehydration; consequently, moderate alcohol consumption is recommended during prolonged exercise
• C. Alcohol blocks hypothalamic osmoreceptors permanently, causing a lasting inability to regulate sodium and water balance even after a single drinking episode
• D. Alcohol inhibits ADH secretion from the pituitary, increasing urine output and risking dehydration, so drinking alcohol without also consuming water or electrolytes can cause net fluid loss

Answer: (D)
