A nurse is reviewing the medical record of a toddler who has moderate dehydration. Which of the following findings should the nurse expect?
Decreased hematocrit
Increased respiratory rate
Decreased heart rate
Increased platelet count
The Correct Answer is B
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.

Explanation
A. Modeling clay: Correct. This is appropriate for a 4-year-old, helping with fine motor skills and creativity.

Correct Answer is B
Explanation
A. "This will not be painful, just a little uncomfortable." While this statement might provide some reassurance, it does not actively engage the child or make the task of taking deep breaths more enjoyable.
B. "Let's play a game of blowing cotton balls across your table." This is the best choice as it makes deep breathing fun and engaging for the child, encouraging them to participate without feeling like it’s a chore.
C. "Do you want to take deep breaths for me now?" This approach is too passive and doesn't engage the child actively or make the activity interesting.
D. "You can't go to the playroom until you finish doing your deep breathing." This approach can create negative reinforcement and might make the child associate deep breathing with punishment or coercion, which is not desirable.
