The nurse is caring for several clients with vomiting and diarrhea. One client is a 2-month-old child who has been ill for one day. Another client is a 30-year-old female who weighs 160 pounds
The third client is a 50-year-old male who weighs 170 pounds, and the fourth client is a 70-year-old female who weighs 120 pounds. The adult clients have been ill for about two days each. The nurse identifies which of the following clients as being at the lowest risk for dehydration? 1. The 2-month-old child
2. The 30-year-old female
3. The 50-year-old male
4. The 70-year-old female

Rationale: The 30-year-old woman is at the lowest risk, as fat contains very little water, and women have more body fat than men. The child would be at greatest risk, as the total water make-up of the child is greater than that of adults (80% of body weight). The 50-year-old male is at risk because he is not overweight; his body is lean and contains more water. The older client is slim, and her body weight is less than 50% water, as body fluid declines with age.
