A nurse at an urgent care clinic is caring for a child who hit her head on the playground at school 30 minutes ago. Which of the following findings is the nurse's priority?

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:
The nurse should report the finding of a 6-month-old infant with a spiral fracture to a lower extremity to local authorities. Spiral fractures in infants, especially those who are not yet independently mobile, raise concerns about possible child abuse or non-accidental trauma. The unique pattern of spiral fractures is often associated with twisting forces, which are unlikely to occur accidentally in infants who cannot perform such movements. Reporting such cases is essential to ensure the safety and well-being of the child.
Choice B rationale:
A 9-month-old infant exposed to bedbugs and cellulitis is not an emergency that requires reporting to local authorities. While cellulitis can be serious, it is not an immediate threat to the child's safety, and the focus should be on providing appropriate medical care.
Choice C rationale:
A 4-year-old preschooler with rivalry among siblings does not indicate a need for reporting to local authorities. Sibling rivalry is a common occurrence in families and does not pose a threat to the child's safety. It is a social and developmental issue that can be addressed within the family.
Choice D rationale:
A 24-month-old toddler experiencing occasional incontinence does not require reporting to local authorities. Occasional incontinence can be a normal part of toddler development as they learn to control their bladder. It does not indicate abuse or immediate danger to the child.
