Question: 1 / 400

What are early signs and symptoms of dehydration?

Coma and seizures

Sunken eyeballs and poor skin turgor

Increased heart rate with hypotension

Thirst and confusion

Thirst and confusion are indeed early signs and symptoms of dehydration. Thirst is the body's natural response to fluid loss, signaling that the individual needs to replenish fluids to maintain homeostasis. As dehydration progresses, cognitive changes can occur, leading to confusion or altered mental status. This happens because a decrease in body fluids can cause electrolyte imbalances and affect brain function, resulting in lethargy or confusion.

While other options listed may represent more advanced stages or severe dehydration, thirst and confusion are among the first indicators that the body is in need of hydration. Recognizing these early signs allows for prompt intervention, which is crucial in preventing further complications associated with dehydration. It is important for healthcare providers to monitor these signs and respond swiftly to address fluid deficits in patients.
