Endocrinology Exam Questions and Answers

Correct Answer: A

Rationale: While African race is considered a protective factor against the development of osteoporosis due to higher peak bone mass and lower fracture rates compared to other races, the other factors listed (current cigarette smoking, female sex, and physical inactivity) are all established risk factors for the development of osteoporotic fractures. African-American individuals, in general, have a lower risk of osteoporosis and fractures compared to Caucasians and Asians.

Correct Answer: D

Rationale: Neuropathic pain due to diabetes can present with a variety of symptoms, including burning pain, electric shock quality, and tingling sensation. These symptoms are commonly reported by individuals with diabetic neuropathy, which is the most common form of neuropathic pain associated with diabetes. The combination of these sensations can significantly impact the quality of life for those living with diabetes and neuropathic pain. Therefore, all of the above options are consistent with neuropathic pain due to diabetes.

Correct Answer: D

Rationale: Neurogenic diabetes insipidus is due to a deficiency in vasopressin (antidiuretic hormone, ADH) production in the hypothalamus or a failure of proper vasopressin release from the posterior pituitary. Causes of neurogenic DI typically involve factors affecting vasopressin synthesis, storage, or release. However, mutations in the vasopressin gene itself would be a cause of genetic forms of diabetes insipidus, not neurogenic diabetes insipidus. Common causes of neurogenic diabetes insipidus include traumatic brain injury, brain tumors, pituitary adenomas, meningitis, and Sheehan's syndrome.

Rationale: Hyperuricemia is a medical condition characterized by elevated levels of uric acid in the blood. This can lead to the formation of urate crystals, which are responsible for various health problems. The three main conditions associated with hyperuricemia are cardiovascular disease (A), gouty arthritis (B), and nephrolithiasis (C).
