A patient asks how oxygen is transported in the body. The nurse's best response is that most ox-ygen (O2) is transported:

a. dissolved in the plasma.
b. bound to hemoglobin.
c. in the form of carbon dioxide (CO2).
d. as a free-floating molecule.

ANS: B
Most O2 is transported bound to hemoglobin, not as a free-floating molecule; only a small amount is dissolved in plasma. O2 is not transported in the form of CO2. O2 is transported bound to he-moglobin.
