A nurse is assisting with the care of an adolescent. Complete the following sentence by using the lists of options. The adolescent is at risk for developing dropdownas evidenced bydropdown

Rationale for correct choices: • compartment syndrome: The adolescent exhibits increasing pain despite repeated analgesia, numbness and tingling in the affected extremity, difficulty moving toes, and diminished dorsalis pedis pulse. These findings indicate compromised perfusion and rising pressure within the casted leg, consistent with the early stages of compartment syndrome, which is an orthopedic emergency requiring immediate intervention. • decreased dorsalis pedis pulse: A decreasing dorsalis pedis pulse from 2+ to 1+, along with delayed capillary refill and edema, reflects impaired arterial blood flow distal to the cast. Monitoring pulses is critical for early detection of compartment syndrome and assessing the severity of vascular compromise in the affected limb. Rationale for incorrect choices: • malunion: Malunion refers to improper bone healing over time and would present weeks after fracture reduction or casting. The current acute symptoms of pain, numbness, and pulse changes are not indicative of malunion. • physeal damage: Physeal (growth plate) injury occurs in fractures involving the epiphyseal plate and presents with growth disturbances over months. There is no specific evidence here of growth plate involvement, and the urgent neurovascular signs are more consistent with compartment syndrome. • infection: Although increasing temperature and local edema could suggest infection, the adolescent’s acute neurovascular changes, severe pain unrelieved by morphine, and decreased pulses are more indicative of compartment syndrome rather than infection at this stage. • inability to ambulate: The adolescent is still able to move the other extremities and previously moved the affected toes. While pain limits mobility, inability to ambulate alone is not a primary indicator of compartment syndrome. • edema of toes: Toe edema is present but is a secondary finding and nonspecific; it supports but does not solely define compartment syndrome. Decreased pulse and pain are more critical indicators.
