Which of the following statements matches correctly the term with the correct description.

A. Obtunded: Obtunded patients show decreased alertness and respond slowly to stimuli, often requiring repeated stimulation to maintain attention. This level of consciousness is more severe than confusion and typically involves reduced awareness.

B. Coma: Coma is a state of deep unconsciousness where the patient is unarousable and unresponsive to external stimuli. It is much more severe than confusion or disorientation and is unlikely in a patient who is still able to interact, even if confused.

C. Stupor: Stupor refers to a condition where the patient is mostly unresponsive and only responds to vigorous or painful stimuli. It is more severe than confusion and involves markedly diminished awareness.

D. Delirium: Delirium is characterized by acute onset of confusion, disorientation, impaired attention, and fluctuating levels of consciousness. It best matches the patient's symptoms of confusion, disorientation, and inability to focus.

E. Mild lethargy: Mild lethargy involves drowsiness and reduced energy but does not typically impair orientation or the ability to focus as severely as seen in this patient.

A. Presence of insulin autoantibodies that destroy beta cells in the pancreas: This describes the autoimmune process characteristic of Type 1 diabetes mellitus, where the immune system attacks pancreatic beta cells, leading to insulin deficiency.

B. Need for lifelong insulin injections: Lifelong insulin therapy is typically required in Type 1 diabetes due to absolute insulin deficiency. Many individuals with Type 2 diabetes can manage their condition initially with lifestyle changes and oral medications.

C. Increase of glucagon secretion from beta cells of the pancreas: Glucagon is secreted by alpha cells, not beta cells, in the pancreas. Dysregulation of glucagon contributes to hyperglycemia but is not a defining feature distinguishing Type 2 diabetes.

D. Resistance to insulin by insulin-sensitive tissues: Type 2 diabetes is primarily characterized by insulin resistance, where muscle, fat, and liver cells do not respond properly to insulin, leading to elevated blood glucose levels despite normal or increased insulin production. This resistance is a hallmark feature distinguishing it from Type 1 diabetes.
