Which statement by a client with a cast on the right forearm indicates the need for further follow-up by the nurse?

The statement indicating the need for further follow-up is the one about feeling tingling in the right arm. Tingling can be a sign of nerve compression or impaired circulation, which may be caused by a cast that is too tight, swelling underneath the cast, or other complications related to the injury. This symptom suggests that the patient may be experiencing a significant problem that could affect the health and functionality of the arm, warranting immediate assessment and potential intervention by the nurse.

Furthermore, the other statements, while they may indicate areas for regular monitoring or follow-up, do not suggest an immediate concern like the tingling does. Pain medication is expected, wanting family members to sign the cast is a normal social interaction, and tightness with the need for elevation could be associated with typical post-cast care, indicating that the cast is applying pressure as it should during the healing process. In contrast, tingling is abnormal and needs prompt evaluation to prevent serious complications.
