Final answer:
When administering a hypertonic solution, health personnel should watch for signs of dehydration.
Step-by-step explanation:
A hypertonic solution refers to a solution that has a higher concentration of solutes (dissolved substances) compared to another solution with which it is compared. This difference in concentration leads to the movement of water from an area of lower solute concentration (hypotonic) to an area of higher solute concentration (hypertonic) through a process called osmosis.
When administering a hypertonic solution, the health personnel should closely watch for signs of dehydration. Hypertonic solutions have a higher solute concentration than body fluids, causing osmotic pressure to increase and fluid to move from the tissues into the blood. This can lead to a net loss of body water, resulting in dehydration.
