QUESTION
Which of the following inhibits release of ADH?
OPTIONS
(A) Hyperosmotic ECF
(B) Low Blood volume
(C) Anxiety
(D) Alcohol
ANSWER
(D) Alcohol
EXPLANATION
Alcohol is the correct option because alcohol suppresses ADH release from the posterior pituitary, reducing renal water reabsorption and increasing urine output. Hyperosmotic extracellular fluid and low blood volume normally stimulate ADH secretion, while anxiety can also increase ADH rather than inhibit it.
