Increased appetite, weight gain, and bloating.
Polyuria, polydipsia, and polyphagia.
Pallor, palpitations, and pain.
Panic attacks, paranoia, and paresthesia.
The Correct Answer is B
The "three P's" of diabetes mellitus refer to polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger) due to the body's inability to effectively use glucose for energy.
Incorrect choices:
a. This choice is incorrect. Increased appetite, weight gain, and bloating are not characteristic of diabetes mellitus; rather, diabetes is associated with weight loss despite increased appetite (polyphagia).
c. This choice is incorrect. Pallor, palpitations, and pain are not specific manifestations of diabetes mellitus.
d. This choice is incorrect. Panic attacks, paranoia, and paresthesia are not typical clinical manifestations of diabetes mellitus.

Correct Answer is C
Explanation
Type 1 diabetes mellitus is characterized by an autoimmune destruction of pancreatic beta cells, leading to an absolute insulin deficiency. It is not primarily characterized by insulin resistance (choice a) and is not typically diagnosed in adulthood (choice b). Oral hypoglycemic agents (choice d) are not the mainstay of treatment for type 1 diabetes.
Correct Answer is C
Explanation
In type 2 diabetes, insulin resistance occurs, meaning that the body's cells do not respond effectively to the action of insulin. This leads to decreased glucose uptake by cells and elevated blood sugar levels.
Incorrect choices:
a. This choice is incorrect. Autoimmune destruction of pancreatic beta cells is characteristic of type 1 diabetes, not type 2.
b. This choice is incorrect. Increased sensitivity of cells to insulin would result in improved glucose uptake and reduced hyperglycemia.
d. This choice is incorrect. Excess insulin production by the pancreas is not a typical mechanism in type 2 diabetes.
