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.

Correct Answer is D
Explanation
A. A school-age child who cries when the nurse is giving him an injection: Crying during an injection is a normal reaction for a child and does not indicate abuse.
B. A toddler who has multiple bruises on the shins of both legs and his parents report that he is clumsy: Bruises on the shins are common in toddlers due to normal play and falls. Without other concerning signs, this does not strongly indicate abuse.
C. A preschooler who has a BMI indicating obesity: While childhood obesity can be a sign of neglect in some cases, it is not a specific or immediate indicator of abuse without other signs.
D. An adolescent who asks to stay in the hospital because he likes the room: This is concerning because it might indicate that the adolescent is not feeling safe or comfortable at home, which could be a sign of abuse or neglect.
