A nurse is reviewing the medical record of a toddler who has moderate dehydration. Which of the following findings should the nurse expect?

A. Decreased hematocrit: Hematocrit usually increases in dehydration due to the concentration of red blood cells in a smaller volume of plasma. B. Increased respiratory rate: Dehydration can lead to tachypnea (increased respiratory rate) as the body attempts to compensate for the decreased blood volume and maintain oxygen delivery. C. Decreased heart rate: Dehydration typically causes tachycardia (increased heart rate) as the body tries to maintain adequate blood circulation and pressure. D. Increased platelet count: Dehydration does not typically affect platelet count significantly, though it may concentrate blood components, including platelets, making them appear elevated on a lab test.
