Which of the following are signs of dehydration in a patient?

Dehydration occurs when the body loses more fluids than it takes in, leading to an imbalance that can significantly affect bodily functions. The signs identified in the correct choice—dry mouth, decreased urine output, and confusion—are classic indicators of dehydration.

A dry mouth signifies that there is insufficient saliva due to lack of fluids. Decreased urine output is a direct result of the body conserving fluid due to dehydration; the kidneys will produce less urine when the body is in need of hydration. Confusion can arise as a symptom of severe dehydration, affecting the brain's ability to function properly when it does not receive adequate hydration.

Recognizing these signs is crucial for timely intervention, as dehydration can lead to serious health complications if not addressed promptly. Understanding these symptoms helps healthcare workers assess patients and implement appropriate fluid management strategies.
