The cells in the blood are normally in an isotonic environment. The different solutes present in and out of blood cells are sufficiently balanced that water movement through osmosis is at equilibrium.
Intravenous (IV) solutions administered to patients ae normally isotonic. Which of the following is most likely if an IV ofdistilled water is administered to a patient?
A. The cells that are exposed to hypotonic solutions will expand as water moves osmotically into the cells from the blood.
B. The cells that are exposed to hypotonic solutions will shrink as a result of salt moving out of the cells into the blood.
C. The cells that are exposed to hypertonic solutions will expand as a result of salt moving into the cells from the blood.
D. The cells that are exposed to hypertonic solutions will shrink as water moves out of the cells and into the blood.
