6. The hormone responsible for promoting conservation of sodium in the kidney is
a. aldosterone.
b. the antidiuretic hormone.
c. angiotensin.
d. renin.
ANS: A
Aldosterone is produced by the adrenal glands, which trigger the kidneys’ nephrons to
reabsorb sodium. NURSINGTB.COM

7. Mr. J. consumes approximately 1500 mL/day from fluid contained in liquids and foods and
from the metabolism of foods. What percent of his fluid requirement does he meet if he
requires 2400 mL/day?
a. 41%
b. 51%
c. 62%
d. 84%
ANS: C
The intake from liquids, liquids in foods, and metabolism is approximately 1500 mL/day, so
1500 mL ÷ 2400 mL = 62%.
