What are common signs of dehydration CNAs should recognize?

• A. Increased appetite and energy.
• B. Clear urine and normal skin turgor.
• C. Dry mouth, darker urine, dizziness, confusion, sunken eyes, and reduced skin turgor.
• D. Rapid weight gain.

Answer: (C)

Dehydration shows up in the body when there isn’t enough fluid to keep tissues and organs functioning well. The signs CNAs should look for include a dry mouth, darker urine, dizziness, confusion, sunken eyes, and reduced skin turgor. A dry mouth happens when fluids are low. Darker, more concentrated urine signals the kidneys are conserving water. Dizziness and confusion can occur from lower blood volume and electrolyte imbalance, while sunken eyes and skin that doesn’t bounce back quickly when pinched (reduced skin turgor) point to fluid loss. It’s helpful to know that in older adults, skin turgor may not be as reliable a clue as other signs, so monitoring changes in mental status, mucous membranes, and urine color becomes especially important.

In contrast, signs like increased appetite and energy suggest adequate or good hydration and nutrition. Clear urine with normal skin turgor indicates proper hydration, not dehydration. Rapid weight gain points to fluid retention or edema rather than dehydration.

For a CNA, recognizing these dehydration signs means promptly reporting them to the nurse, documenting intake and output if possible, and assisting with fluids as allowed by the care plan to help prevent further dehydration and potential complications.
