Which of the following symptoms might require urgent assessment in a paraplegic patient?

The new onset of severe headache in a paraplegic patient warrants urgent assessment because it could indicate a serious underlying condition that may require immediate medical intervention. In individuals with spinal cord injuries, such as paraplegia, the presence of a severe headache might suggest complications such as increased intracranial pressure, hemorrhage, or other neurological issues that could pose significant risks if not addressed promptly.

Stable vital signs, minor bruising, and previous medical history are not typically indications for urgent assessment in this context. Stable vital signs suggest that the patient is currently physiologically stable, minor bruising usually does not require urgent intervention unless associated with other significant symptoms, and previous medical history, while important for overall patient care, does not indicate an immediate need for evaluation unless it relates directly to an acute change in the patient's condition.
