Question 2

A patient presents to the emergency department complaining of increased urine output. The patient has been drinking alcohol and is still visibly impaired.

Answer to Question 1

D
The hypothalamus controls release of ADH from the posterior pituitary gland. Antidiuretic hor-mone circulates to the kidneys, where it acts on the collecting ducts, causing them to reabsorb water. The adrenal cortex releases aldosterone in response to increased plasma potassium con-centration or as the end product of the renin-angiotensin-aldosterone system (RAAS).

Answer to Question 2

A
Ethyl alcohol decreases ADH release, which is why people urinate frequently when they drink alcoholic beverages. Antidiuretic hormone acts on the kidneys, causing them to reabsorb water. With ADH stimulation a patient will experience a decrease in urinary output; volume is returned to systemic circulation, diluting the blood and decreasing osmolarity. Insensible water loss is continuous and nonperceptual. Lungs expire water daily through respiration. Angiotensin II causes vasoconstriction of many blood vessels, which helps regulate blood pressure, and it sti-mulates the release of aldosterone, which assists fluid homeostasis.
