Which disorder is associated with the compression of the bilateral nerve roots of the lumbosacral region?
Anterior spinal artery syndrome
Cauda equina syndrome
Horner's syndrome
Brown-Séquard syndrome
The Correct Answer is B
Choice A rationale: Anterior spinal artery syndrome is caused by ischemia of the anterior two-thirds of the spinal cord, resulting in loss of motor function and pain and temperature sensation below the level of the lesion.
Choice B rationale: This is a condition that occurs when the nerve roots in the lower end of the spinal cord are compressed, causing symptoms such as lower back pain, sciatica, saddle anesthesia, bladder and bowel dysfunction, and sexual dysfunction.
Choice C rationale: Horner's syndrome is caused by damage to the sympathetic nerve fibers in the neck or chest, resulting in drooping eyelid, constricted pupil, and lack of sweating on one side of the face.
Choice D rationale: Brown-Séquard syndrome is caused by hemisection of the spinal cord, resulting in ipsilateral loss of motor function and proprioception and contralateral loss of pain and temperature sensation below the level of the lesion.

Correct Answer is C
Explanation
Choice A rationale: Clients with Graves' disease may have increased sensitivity to light due to ocular manifestations like photophobia, so keeping the room well-lit may can cause eye irritation.
Choice B rationale: Encouraging frequent ambulation and exercise may worsen the symptoms of hyperthyroidism, such as tachycardia, palpitations, and tremors.
Choice C rationale: This is because clients with Graves' disease have an increased
metabolic rate and may experience weight loss, muscle wasting, and fatigue. A high- calorie and high protein diet can help prevent these complications and provide adequate nutrition for the client.
Choice D rationale: Placing extra blankets over the client may increase the body temperature and cause heat intolerance, which is another common symptom of Graves' disease.
