Verified step by step guidance

Understand the physiological factors that contribute to dehydration risk in infants. Infants have different anatomical and physiological characteristics compared to adults.

Consider the role of kidney function in fluid balance. Efficient kidneys are crucial for maintaining fluid and electrolyte balance, and infants have immature kidneys that are less efficient at concentrating urine.

Evaluate the metabolic rate. While infants have a higher metabolic rate compared to adults, this factor alone does not directly increase dehydration risk.

Analyze the surface area to volume ratio. Infants have a higher surface area to volume ratio, which can lead to greater water loss through the skin, but this is not the primary factor in dehydration risk.

Consider lung volume. High residual lung volume is not typically associated with dehydration risk in infants. Focus on the inefficiency of the kidneys as the primary factor.
