A nurse educator is providing an educational in-service about various neurological disorders. Which statement should be included when teaching about Guillain-Barre Syndrome?

Guillain-Barre Syndrome is a contagious disease spread by respiratory droplets.

Guillain-Barre Syndrome causes demyelination in the central nervous system.

Guillain-Barre Syndrome is a genetic disorder.

Guillain-Barre Syndrome affects the peripheral nervous system.

Answer and Explanation

The Correct Answer is D

A.   Guillain-Barre Syndrome is not a contagious disease. It is an autoimmune disorder that occurs when the immune system mistakenly attacks the peripheral nerves. GBS is not spread through respiratory droplets or any other form of infection transmission.
B.   Guillain-Barre Syndrome causes demyelination in the peripheral nervous system, not the central nervous system. The central nervous system includes the brain and spinal cord, whereas the peripheral nervous system comprises the nerves outside the brain and spinal cord.
C.   Guillain-Barre Syndrome is not a genetic disorder. It is considered an autoimmune condition that can be triggered by an infection or other environmental factors. While there may be genetic predispositions that affect susceptibility to autoimmune conditions, GBS itself is not classified as a genetic disorder.
D.   Guillain-Barre Syndrome primarily affects the peripheral nervous system. It involves an immune- mediated attack on the peripheral nerves, leading to symptoms such as muscle weakness, tingling, and loss of reflexes.

Correct Answer is C

Explanation

A. This statement is not accurate in the context of miotic medications. Miotic drugs do not work by blocking neural impulses to the muscles. Instead, they directly affect the eye's pupil size and fluid dynamics. This response does not correctly describe the action of miotic agents.
B. This response is incorrect because miotic medications actually constrict the pupil, not dilate it. In acute angle-closure glaucoma, dilation of the pupil would worsen the condition by further blocking the drainage angle. Miotics are used to constrict the pupil, which helps open the angle between the iris and the cornea, thereby facilitating fluid drainage.

C. Miotic medications cause the pupil to constrict (miosis), which helps in opening the narrow angle between the iris and the cornea. In acute angle-closure glaucoma, the angle is closed or narrow, preventing proper drainage of aqueous humor. By constricting the pupil, miotic medications can help to relieve this obstruction and allow better drainage of fluid, thereby reducing intraocular pressure.
D. This statement is incorrect regarding the action of miotic medications. Miotic drugs do not pull aqueous humor into the bloodstream. Their primary effect is on the pupil's size and the angle of the eye to improve drainage. Medications that reduce aqueous humor production or increase its outflow, such as carbonic anhydrase inhibitors or prostaglandin analogs, are responsible for these actions

A. Low adrenocorticotropic hormone (ACTH) and low cortisol B. Elevated adrenocorticotropic hormone (ACTH) and elevated cortisol C. Low adrenocorticotropic hormone (ACTH) and elevated cortisol D. Elevated adrenocorticotropic hormone (ACTH) and low cortisol

Correct Answer is C

Explanation

A. This would indicate adrenal insufficiency, not Cushing syndrome.
B. Elevated adrenocorticotropic hormone (ACTH) and elevated cortisol would indicate Cushing syndrome caused by pituitary adenoma, not adrenal gland hyperplasia.
C. Low adrenocorticotropic hormone (ACTH) and elevated cortisol is consistent with Cushing syndrome caused by adrenal gland hyperplasia. In this condition, the adrenal glands produce excess cortisol independently of ACTH stimulation.
D. Elevated adrenocorticotropic hormone (ACTH) and low cortisol would indicate adrenal insufficiency, not Cushing syndrome.
