What is a common inhibitory neurotransmitter?

Choice A reason: Genetic mutations causing insulin resistance describe type 2 diabetes. Type 1 diabetes results from autoimmune destruction of beta cells, leading to absolute insulin deficiency, not resistance, making this choice incorrect.

Choice B reason: Excessive carbohydrate intake does not cause type 1 diabetes, which is autoimmune. It may exacerbate hyperglycemia in diabetes but is not the primary cause, making this choice incorrect.

Choice C reason: Pancreatic damage from alcohol can cause pancreatitis, not type 1 diabetes. Type 1 is autoimmune, destroying insulin-producing beta cells, unrelated to alcohol-induced damage, making this choice incorrect.

Choice D reason: Type 1 diabetes is caused by autoimmune destruction of pancreatic beta cells, leading to absolute insulin deficiency. Autoantibodies target beta cells, causing hyperglycemia, making this the correct pathophysiological cause.

Choice A reason: A GCS score of 6 is too low. Eye-opening to speech (3), moaning (2), and abnormal extension (2) total 7, not 6. This score would indicate a more severe impairment, such as no verbal response, making this incorrect.

Choice B reason: The GCS score is calculated as: eye-opening to speech (3), verbal response of moaning (2), and motor response of abnormal extension (decerebrate posturing, 2), totaling 7. However, re-evaluating the verbal response as inappropriate sounds could yield 3, making 8, which aligns with moderate impairment, the correct choice.

Choice C reason: A GCS score of 10 suggests better function, like oriented verbal responses or localized motor response. Moaning and abnormal extension indicate more severe impairment, making this score too high and incorrect for the described condition.

Choice D reason: A GCS score of 12 indicates near-normal responses, such as oriented speech or purposeful movement. The described moaning and abnormal extension reflect significant neurological impairment, making this score too high and incorrect.
