Answer to Question 1

D
Feedback:
To replace any lost bicarbonate, the renal tubular cells generate new bicarbonate through a variety of chemical reactions. This newly generated bicarbonate is then reabsorbed by the tubules and returned to the body. This makes options A, B, and C incorrect.

Answer to Question 2

A
Feedback:
In adult men, adverse effects include inhibition of testicular function, gynecomastia, testicular atrophy, priapism, baldness, and change in libido. Increased fertility, increased urination, and hoarseness would not be expected assessment findings.
