The nurse is teaching a client about the effects of taking in increased amounts of sodium. The nurse explains that a hypertonic solution results from excessive intake of sodium, which causes the cells of the body to:
1. neither gain nor lose water.
2. absorb water, swell, and, eventually burst.
3. lose water and shrink.
4. leak out of the area they are in.
Answer: 3
1. Cells do not gain or lose water in an isotonic solution, which is the norm in the body.
2. In hypotonic or low-sodium solutions, cells swell and burst.
3. In hypertonic solutions, water is drawn from the cells because of high sodium levels outside the cell, and the cells shrivel.
4. Cells in tissues do not move from their area. However, blood cells can move at times.
