1. Dehydration can impair cognitive function and exacerbate neurological conditions such as migraines and seizures.
2. Chronic dehydration may lead to compromised pulmonary health by thickening mucus secretions and reducing lung function.
3. Adequate hydration is crucial for maintaining skin elasticity and preventing conditions like pressure ulcers in the integumentary system.
4. Muscle cramps and weakness are common symptoms of dehydration due to electrolyte imbalances affecting muscular function.
5. Nurses play a vital role in assessing hydration status through clinical signs like skin turgor, urine output, and mucous membrane moisture.
