When caring for a patient after lumbar spinal surgery, the nurse would immediately report which finding to the healthcare provider?

Choice A rationale

Loss of sensation to the perineum, buttocks, inner thighs, and back of the legs may indicate cauda equina syndrome, a surgical emergency. This condition involves compression of the spinal nerve roots and can lead to permanent neurological damage if not promptly addressed. Immediate medical intervention is critical.

Choice B rationale

Nausea and delayed voiding postoperatively are common, potentially due to anesthesia effects or limited mobility. While these findings warrant monitoring, they do not typically indicate an urgent issue unless prolonged or associated with other complications.

Choice C rationale

Mild low back pain is expected after lumbar spinal surgery due to manipulation of spinal structures. Pain management with prescribed analgesics and gradual mobilization is part of the standard postoperative care plan, and it does not usually necessitate immediate reporting.

Choice D rationale

A single episode of emesis can result from anesthesia effects or medication. Unless accompanied by persistent vomiting, signs of aspiration, or electrolyte imbalances, isolated emesis is not typically urgent and should be managed with antiemetics if necessary.
