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

Choice A rationale Comparing the temperature of both legs can help identify potential circulatory issues or infections. However, temperature differences are not the most immediate concern when assessing a child with a long-leg cast. Monitoring neurovascular status, including circulation and nerve function, is more critical to ensure there are no complications such as compartment syndrome or impaired blood flow. Choice B rationale Monitoring capillary refill of the toes is crucial for assessing the circulatory status of the affected limb. Capillary refill time indicates how well blood is perfusing to the extremities. A delayed capillary refill time can suggest compromised circulation, which could lead to serious complications like tissue ischemia. This assessment helps ensure that the cast is not too tight and that there is adequate blood flow to the toes. Choice C rationale Examining for spontaneous movement is important for assessing motor function and ensuring that there is no nerve damage. However, it is not as immediate a concern as circulatory assessment. Spontaneous movement can indicate intact motor function, but circulatory compromise would need to be addressed urgently to prevent tissue damage. Choice D rationale Palpating femoral pulses is important for assessing the overall circulation to the lower extremities. However, in the context of a long-leg cast, it is more relevant to directly assess the area distal to the cast (such as the toes) for adequate perfusion. Checking femoral pulses alone does not provide specific information about potential compartment syndrome or tightness of the cast affecting distal circulation.
