Which of the following is a common sign that a cast may be too tight?

A burning sensation over the casted area is indeed a common sign that a cast may be too tight. This sensation can indicate increased pressure on the underlying tissues and nerves, which may be caused by swelling or improper cast application. It is a signal that blood flow and nerve function may be compromised in the area. Without timely intervention, this lack of circulation can lead to more serious complications like skin ulcers or even tissue necrosis.

While numbness in the fingers or toes can also suggest circulatory issues, a burning sensation is more specifically linked to the immediate pressure and discomfort caused by a tight cast. Therefore, being vigilant about symptoms like burning sensations is crucial for maintaining the health of the affected limb and ensuring proper recovery.
