The nurse is caring for a child with a unilateral long-leg cast applied for the correction of club foot. Which action is most important for the nurse to perform?

Choice A reason: Palpating femoral pulses assesses proximal circulation but may miss distal issues like cast-related compression, which directly affects the foot’s perfusion in club foot correction. Choice B reason: Monitoring capillary refill of the toes directly evaluates distal circulation and detects cast-induced neurovascular compromise, critical for preventing ischemia or nerve damage in the affected limb. Choice C reason: Spontaneous movement indicates comfort but not circulation status; a child may move despite impaired blood flow, making it less reliable than capillary refill assessment. Choice D reason: Comparing leg temperatures detects inflammation or circulation differences but is less specific than capillary refill for immediate neurovascular complications in a casted limb.
