A nurse is reinforcing teaching to a client who has multiple sclerosis about factors that can worsen their manifestations. Which of the following factors should the nurse include in the teaching?

Complete spinal cord injury causes total disruption of motor pathways, ascending sensory transmission, spinal reflex activity, and voluntary neurologic function below the lesion level. Injury at T6 commonly produces paraplegia, autonomic dysfunction, loss of sensation, bowel and bladder impairment, and absent voluntary movement distally.

Rationale:

A. Full neurologic recovery is not expected with a complete spinal cord injury because total interruption of spinal cord conduction pathways has occurred. Permanent deficits commonly persist below the lesion level despite rehabilitation and supportive care. Complete injury causes irreversible neuronal damage and profound functional impairment affecting mobility and sensation.

B. Partial movement below the injury level is characteristic of incomplete spinal cord injuries where some neural pathways remain intact. Complete injuries involve total absence of voluntary motor and sensory conduction distal to the lesion. Loss of descending motor control and absent neurologic transmission prevent preserved movement below T6.

C. Complete spinal cord injury results in absence of both motor and sensory function below the affected spinal level. Clients lose voluntary movement, tactile sensation, pain perception, and autonomic control distal to the lesion. Total disruption of spinal cord conduction produces profound neurologic deficits and paraplegia below the injury site.

D. Isolated sensory loss without motor impairment does not occur in complete spinal cord injury because both ascending sensory and descending motor pathways are fully interrupted. Clients experience combined paralysis and sensory absence below the lesion. Severe motor dysfunction accompanies extensive sensory impairment in complete spinal cord injuries.

In spinal cord injury prolonged immobilization promotes venous thromboembolism through venous stasis, endothelial injury, and hypercoagulability leading to thrombus formation in deep veins of lower extremities pathophysiology explained in brief

Rationale:
A. Warmth on right leg indicates localized inflammatory response consistent with venous thrombosis in immobilized spinal cord injury patients. It reflects increased blood flow and cytokine-mediated vessel dilation around a clot. This finding strongly suggests deep vein thrombosis requiring prompt evaluation immediately.

B. Inflammation irritation calf suggests deep vein thrombosis inflammatory process in immobilized spinal cord injury client. It occurs due to fibrin clot formation causing endothelial activation and leukocyte infiltration. These localized signs require urgent assessment to prevent pulmonary embolism risk high.

C. Capillary refill less than 3 seconds indicates adequate peripheral perfusion and normal vascular status. It reflects intact microcirculation and sufficient oxygen delivery state maintained. In spinal cord injury this finding is clinically nonpathologic here. No immediate follow-up required clinically here.

D. Pedal pulses of 3+ indicate strong palpable arterial flow in the affected extremity. This finding suggests intact arterial circulation despite possible venous obstruction. In deep vein thrombosis arterial pulses are typically preserved clinically. This finding is not emergent for DVT.

E. Four plus edema of the right leg indicates severe unilateral swelling associated with venous obstruction. It results from impaired venous return and increased hydrostatic pressure. This is a classic sign of deep vein thrombosis present. Requires urgent evaluation now clinically.
