What is a common sign of dehydration in an infant that the nurse should look for?

A common sign of dehydration in an infant that a nurse should look for is dry mucous membranes. Dehydration can lead to a reduction in fluid levels in the body, which can cause the mucous membranes in the mouth and throat to become less moist than usual. This dryness is a distinctive indicator of dehydration and highlights the body's inadequate hydration status.

Other signs that may accompany dehydration can include lethargy, decreased urine output, and changes in behavior or responsiveness. Observing the state of the mucous membranes provides a visual cue that can guide further assessment and intervention. In clinical practice, it is critical for nurses to assess hydration status early, as infants can become dehydrated rapidly, necessitating prompt recognition and treatment. Having moist mucous membranes is a key sign of adequate hydration and overall well-being in infants.
