1. The mineral present in the body in the greatest amount is
a. sodium.
b. calcium.
c. iron.
d. chloride.
ANS: B
Calcium is present in the greatest amount in the body and functions in bone and teeth
formation, blood clotting, muscle and nerve action, and metabolic reactions.
2. The factors most responsible for regulating calcium absorption from food are
a. activity and diet.
b. dietary intake and vitamin D hormone.
c. metabolic rate and cardiovascular function.
d. vitamin D hormone, calcitonin, and parathyroid hormone.
ANS: D
The absorption of dietary calcium depends on the interaction of three hormones—vitamin D,
NURSINGTdirectly
parathyroid hormone, and calcitonin—that B.COcontrol
M absorption along with indirect
metabolic stimuli from the estrogen hormones.
3. Binding agents such as oxalic acid and phytic acid inhibit absorption of
a. potassium.
b. sodium.
c. sulfur.
d. calcium.
ANS: D
Oxalic acid is a compound found in some plants, such as spinach, rhubarb, Swiss chard, beet
greens, and certain other vegetables and nuts, that form insoluble salts with calcium, called
oxalates.
4. The person most at risk for developing osteoporosis is a

d. 14-year-old girl who runs track and drink four glasses of milk daily.
ANS: B
Osteoporosis is not a primary calcium deficiency disease, but it does result from a
combination of factors that create chronic calcium deficiency. These factors include
inadequate intake, poor intestinal absorption connected with hormones controlling calcium
absorption and metabolism, and lack of exercise that stimulates muscle insertion action on
bones and determines the strength, shape, and mass of bone. The 35-year-old woman who is
bedridden is at a higher risk for osteoporosis than the others who are active.
5. An example of a food that is a good source of calcium is
a. kidney beans.
b. whole-grain bread.
c. yogurt.
d. spinach.
ANS: C
Good sources of calcium include milk and milk products, including cheese, yogurt, and ice
cream.

milk products.
