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

Answer and Explanation

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: Conus medullaris syndrome involves injury or compression to the end portion of the spinal cord and can present with various symptoms but not necessarily lack of normal sympathetic outflow leading to shock.

Choice B rationale: Concussion is a mild traumatic brain injury, and the symptoms described align more with spinal cord injury leading to neurogenic shock.

Choice C rationale: Neurogenic shock occurs due to the loss of sympathetic tone and is characterized by bradycardia, low blood pressure, and vasodilation following spinal cord injury at or above the level of the sixth thoracic vertebra.

Choice D rationale: Diffuse axonal injury typically presents with more widespread brain injury-related symptoms and is not associated with the specific spinal cord-related symptoms described.

A. an exam used to detect and help your doctor view the inside of your body without having to make an incision or invasion. This can help them diagnose, monitor, and treat many medical conditions B. an exam used to detect and help your doctor look for a range of disorders and conditions, screen for diseases and adjust treatments, measures and counts your blood cells. C. an exam used to detect and help your doctor view changes or abnormalities in the large intestine and rectum. D. an exam used to detect and help your doctor view for things cannot be seen with the naked eye, including red blood cells, white blood cells (or pus cells), bacteria (germs), or crystals.

Correct Answer is C

Explanation

Choice A rationale: This is a general description of an imaging test, such as an X-ray, ultrasound, or MRI, which can show the structure of the organs but not the mucosal lining.

Choice B rationale: This is a general description of a blood test, which can show signs of infection, inflammation, or anemia, but not the cause of these problems.

Choice C rationale: This exam is called a colonoscopy, which involves inserting a flexible tube with a camera and light into the anus and advancing it through the colon. A colonoscopy can reveal signs of inflammation, ulcers, bleeding, or narrowing of the intestinal wall that are characteristic of Crohn's disease. A biopsy can also be taken during the procedure to confirm the diagnosis.

Choice D rationale: This is a general description of a urine test, which can show signs of kidney problems, urinary tract infections, or dehydration, but not Crohn's disease.
