What are common signs of dehydration in clients?

The correct choice identifies dry mouth, decreased urine output, and confusion as common signs of dehydration in clients.

Dry mouth is a typical symptom because when the body lacks adequate fluids, saliva production diminishes, leading to a sensation of dryness. Decreased urine output is another critical indicator, as the kidneys conserve water in response to dehydration, resulting in less frequent urination and darker urine. Confusion can arise due to the impact of dehydration on cognitive function; as fluid levels drop, the brain may not receive enough hydration to operate optimally, leading to disorientation or altered mental status.

In contrast to the other options, which either mix symptoms that don't align with dehydration or include signs that are less commonly associated with this condition, the combination in the correct choice directly reflects how dehydration presents in many individuals, particularly those who are vulnerable, such as the elderly. This understanding is vital for health aides to monitor clients effectively and respond to signs of dehydration promptly.
