A nurse is caring for an infant who has rotavirus.
Which of the following findings indicates that the infant is moderately dehydrated?
Respiratory rate 28/min.
Capillary refill 1 second.
Weight loss 7%.
Bradycardia.
The Correct Answer is C
A weight loss of 7% indicates that the infant is moderately dehydrated.
Dehydration is classified as mild (3-5% weight loss), moderate (6-10% weight loss), or severe (>10% weight loss)1.
Choice A is wrong because a respiratory rate of 28/min is within the normal range for an infant.
Choice B is wrong because a capillary refill time of 1 second is within the normal range.
Choice D is wrong because bradycardia (a slow heart rate) is not a typical sign of moderate dehydration in infants.
