. A patient is diagnosed with Brown-Sequard syndrome after a spinal cord injury. Which of the following symptoms should the nurse expect?
Loss of pain temperature, and light touch sensation on the same side as the injury
Loss of motor function and deep pressure sensation on the opposite side of the injury
Loss of motor function and position sense on the same side as the injury
Loss of motor function with preserved pain and temperature sensation in the lower extremities
The Correct Answer is C
A. Loss of pain, temperature, and light touch sensation on the same side as the injury. In Brown-Sequard syndrome, pain, temperature, and light touch are typically lost on the opposite (contralateral) side of the injury.
B. Loss of motor function and deep pressure sensation on the opposite side of the injury. Motor function and deep pressure sensation loss occur on the same side (ipsilateral) as the injury.
C. Loss of motor function and position sense on the same side as the injury. Brown-Sequard syndrome is a spinal cord hemisection injury leading to loss of motor function and proprioception on the same side as the injury.
D. Loss of motor function with preserved pain and temperature sensation in the lower extremities. Pain and temperature sensations are lost on the opposite side of the injury in Brown-Sequard syndrome, not preserved.

Correct Answer is B
Explanation
A. High fluid intake: High fluid intake can help maintain blood flow and reduce the risk of venous stasis.
B. Immobility during and after surgery: Immobility contributes to venous stasis and is a primary risk factor for DVT, especially after prolonged surgery.
C. Low body temperature: Low body temperature does not directly cause venous stasis or increase the risk of DVT.
D. Increased physical activity: Increased physical activity promotes circulation and reduces the risk of DVT by preventing blood from pooling in the veins.
Correct Answer is A
Explanation
A. Increased pulse, respirations and blood pressure with dysphagia and respiratory distress. A myasthenic crisis is characterized by severe muscle weakness that can lead to respiratory failure, dysphagia, and increased vital signs due to the stress of respiratory distress.
B. Hypotension, diarrhea, and increased salivation. These symptoms are more indicative of a cholinergic crisis, which is due to excess acetylcholine.
C. Bradycardia and hypothermia. Bradycardia and hypothermia are not characteristic signs of a myasthenic crisis.
D. Tachypnea and hyperactive deep tendon reflexes. While tachypnea can occur in respiratory distress, hyperactive reflexes are not typical in myasthenic crisis, as it involves neuromuscular weakness.
