The nurse is providing teaching to a student nurse about how antidiuretic hormone (ADH) plays a central role in the reabsorption of water by the kidneys.
 
  The nursing student is correct to place the following components of the homeostatic action of ADH in the correct sequence. Use all the options.
  A) Stored ADH is released into circulation.
  B) ADH is transported along a neural pathway to the posterior pituitary gland.
  C) Aquaporins are inserted into tubular cell membranes.
  D) ADH is synthesized by cells in the supraoptic and paraventricular nuclei of the hypothalamus.
  E) Serum osmolality increases.

Question 2

Place the following stages of the hydrogen ion elimination and bicarbonate conservation in the proximal tubules of the nephrons in the ascending chronological order. Use all the options.
 
  A) CO2 and H2O are produced.
  B) H+ is secreting into the tubular fluid.
  C) Carbonic acid is produced.
  D) H+ combines with filtered HCO3-.

Answer to Question 1

Ans:
D, B, E, A, C

Feedback:

ADH is produced in the hypothalamus, sequestered in the pituitary, and is released in response to increased serum osmolality. Its influence on tubular cells is exerted by way of the insertion of aquaporins in the tubular membrane.

Answer to Question 2

Ans:
B, D, C, A

Feedback:

Renal regulation of pH involves the secretion of hydrogen ions into the tubular fluid, the combining of hydrogen ions with bicarbonate yielding carbonic acid, followed by the decomposition of carbonic acid into carbon dioxide and water.
