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 B
Explanation
Choice A rationale: Rotating the neck to one side while observing the eyes moving to the opposite side is a procedure for testing for oculocephalic reflex or doll's eye
phenomenon, which indicates brainstem function.
Choice B rationale: This is the correct answer. Kernig's sign is a clinical sign that indicates meningitis, which is an inflammation of the membranes that cover the brain and spinal cord. To test for Kernig's sign, the nurse should flex the patient's hip to 90 degrees and then attempt to extend the knee. A positive Kernig's sign is when the patient
experiences pain in the lower back or hamstring, resists knee extension, or involuntarily flexes the opposite leg.
Choice C rationale: Stroking the lateral aspect of the sole of the patient's foot and observing for dorsiflexion of the big toe is a procedure for testing for Babinski's sign, which indicates upper motor neuron lesion or damage.
Choice D rationale: Passively flexing the patient's neck forward and observing for hip and knee flexion is a procedure for testing for Brudzinski's sign, which also indicates meningitis.

Correct Answer is D
Explanation
Choice A rationale: Symptoms and findings described align more with an acute, severe condition rather than a chronic one.
Choice B rationale: While cholecystitis can present with similar symptoms, the radiation of pain to the back is more indicative of a different condition.
Choice C rationale: Cholelithiasis (gallstones) might cause abdominal pain but typically doesn’t lead to fever and hypotension.
Choice D rationale: Symptoms including severe abdominal pain, radiation to the back, fever, and hypotension suggest acute pancreatitis, a potentially serious condition requiring urgent medical attention.
