Mrs. B brings her 4-month-old son, Tyler, to the physician's office because he has been experiencing diarrhea for about 24 hours and has taken very little fluid when it has been offered. Mrs. B says she is not sure if she needed to bring Tyler to be examined. The most appropriate response by the nurse would be:
"You did the right thing to bring Tyler in. Babies can become dehydrated quickly."
"Going with very little food for 24 hours is not too long for anyone."
"Most of a baby's body is water, so he is probably very sick."
"Babies have a large water reserve to replace diarrhea."
The Correct Answer is A
A. "You did the right thing to bring Tyler in. Babies can become dehydrated quickly.": Infants are vulnerable to dehydration due to their high water content and immature kidneys.
B. "Going with very little food for 24 hours is not too long for anyone.": This dismisses the concern and doesn't address dehydration risk.
C. "Most of a baby's body is water, so he is probably very sick.": While high water content is true, this statement is vague and potentially alarming.
D. "Babies have a large water reserve to replace diarrhea.": Infants dehydrate quickly because they have low fluid reserves.
