Pediatric ATI Practice Exam

What is a potential complication to assess for after casting a broken limb?

1. Skin irritation

2. Neurovascular impairment

3. Increased muscle tone

4. Improved mobility

The correct answer is: Neurovascular impairment

After casting a broken limb, assessing for neurovascular impairment is crucial due to the risk of reduced blood flow or nerve damage caused by swelling or tightness of the cast. Neurovascular impairment manifests through symptoms such as pain, numbness, tingling, or the inability to move the affected limb properly. These symptoms suggest that the cast may be too tight or that there may be swelling that could compromise blood circulation or nerve function. Monitoring neurovascular status involves evaluating the five P's: pain, pallor, pulselessness, paresthesia, and paralysis. This assessment checks for any signs that the limb may not be receiving adequate blood supply or is affected by nerve compression. If detected early, interventions can be taken to relieve the pressure and prevent more severe complications, such as ischemia or permanent nerve damage. While skin irritation may occur, it is not as critical as assessing neurovascular function due to the potential for significant consequences if circulation or nerve function is compromised. Increased muscle tone and improved mobility are not considered accurate concerns following casting; in fact, muscle tone typically decreases due to immobility, and mobility is often impaired due to the presence of the cast.
