A nurse is reviewing the medical record of a school-age child who was admitted for suspected physical maltreatment. Which of the following findings in the child's medical history should the nurse identify as a potential risk factor for physical maltreatment?

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:
Administer pain medication. Administering pain medication is important for the preschooler's comfort, but it is not the nurse's priority action in this scenario. The priority is to ensure adequate circulation to the extremities, which can be assessed by checking capillary refill.
Choice B rationale:
Check capillary refill. This is the correct answer because the nurse's priority is to assess the child's circulation and tissue perfusion. In 90-90 traction, there is a risk of impaired circulation to the extremities due to the positioning. Checking capillary refill provides information about the adequacy of blood flow to the capillaries and is crucial for early detection of any circulation problems.

Choice C rationale:
Cleanse and dress the pin sites. While caring for the pin sites is important to prevent infection, it is not the priority action at this moment. Ensuring proper circulation and perfusion takes precedence over pin site care.
Choice D rationale:
Reposition the child every 2 hr. Repositioning the child is important to prevent complications associated with immobility, but it is not the nurse's priority action in this situation. The primary concern is to assess and address any circulation issues.
