A nurse is assessing a 3-month-old infant who has diarrhea. Which of the following findings should the nurse expect?
Decreased heart rate
Bulging fontanel
Polyuria
Increased hematocrit
The Correct Answer is D
A. Decreased heart rate: Dehydration typically causes an increased heart rate (tachycardia) rather than a decreased heart rate.
B. Bulging fontanelle: A bulging fontanel can indicate increased intracranial pressure or overhydration. Dehydration, which is more common with diarrhea, would more likely cause a sunken fontanel.
C. Polyuria: Polyuria (increased urine output) is not expected with dehydration. Dehydration often results in oliguria (decreased urine output).
D. Increased haematocrit: Correct. Dehydration can cause hemoconcentration, which leads to an increased haematocrit as the blood becomes more concentrated.
