A nurse is reviewing the laboratory report of a newly admitted school-age child who has a fever. The nurse should identify which of the following laboratory results is an indication of an infection and should be reported to the charge nurse immediately.

Choice A rationale:
Edema. Edema, the accumulation of fluid in the tissues, is not the primary indicator of compartment syndrome. While edema can occur due to various reasons, it's not specific to compartment syndrome. Compartment syndrome primarily involves increased pressure within a closed space (muscle compartment), which can compromise blood circulation and nerve function.
Choice B rationale:
Mottling. Mottling refers to a patchy, bluish discoloration of the skin that occurs due to poor blood circulation and is often seen in critically ill patients. While it might indicate circulatory issues, it's not a direct sign of compartment syndrome. Compartment syndrome is more closely associated with symptoms such as severe pain, numbness, and decreased or absent pulses.
Choice C rationale:
Urticaria. Urticaria, also known as hives, is a skin rash characterized by raised, itchy, and red or white welts. It is typically caused by an allergic reaction or other factors such as medications. Urticaria is unrelated to compartment syndrome, which involves the compression of nerves and blood vessels within a closed anatomical compartment, leading to ischemia and potential tissue damage.
Choice D rationale:
Pulselessness. Pulselessness is a critical sign that the nurse should monitor when conducting a circulatory check for compartment syndrome. Compartment syndrome occurs when there is increased pressure within a confined space (muscle compartment), leading to compromised blood flow and oxygen delivery to the tissues. The lack of a palpable pulse in the affected area suggests that blood flow is severely compromised. This is a late sign of compartment syndrome and requires immediate intervention to prevent tissue necrosis and long-term complications.

Choice A rationale:
Perfectionistic behavior is not typically considered a behavioral finding indicative of sexual abuse in a school-age child. Perfectionism may be related to personality traits, family dynamics, or individual tendencies, but it is not a specific behavioral marker for sexual abuse.
Choice B rationale:
Manipulative behavior is not a specific indicator of sexual abuse in a school-age child. Children can display manipulative behavior for various reasons, including seeking attention or attempting to control situations. While behavioral changes can occur in response to trauma, manipulative behavior alone does not necessarily point to sexual abuse.
Choice C rationale:
Withdrawn behavior is a possible indication of sexual abuse in a school-age child. Sexual abuse can cause emotional and psychological distress in children, leading them to withdraw from social interactions. They might become isolated, exhibit changes in their usual behavior, and show decreased interest in activities they previously enjoyed.
Choice D rationale:
Destructive behavior is not a prominent behavioral finding associated specifically with sexual abuse in a school-age child. Destructive behaviors can arise from a range of factors, including emotional difficulties, behavioral disorders, or reactions to stressors. While trauma like sexual abuse can influence behavior, it's not a defining characteristic of sexual abuse in isolation.
