Endocrinology Exam Questions and Answers Questions

Question 1 of 5

All of the following are featured by dermal hyperpigmentation except:

Correct Answer: A

Rationale: Dermal hyperpigmentation, also known as hyperpigmentation of the skin, is commonly associated with conditions such as Addison's disease, hemochromatosis, and bronchogenic carcinoma. In Addison's disease, there is increased production of melanin due to elevated levels of adrenocorticotropic hormone (ACTH) which stimulates melanocytes. Hemochromatosis can cause hyperpigmentation due to excess iron deposits in the skin. Bronchogenic carcinoma can lead to a condition known as acanthosis nigricans, characterized by dark, velvety discoloration of the skin primarily around the neck and armpits. However, Conn's syndrome, which is a primary aldosteronism resulting from an adrenal adenoma or hyperplasia, is not typically associated with dermal hyperpigmentation.

Question 2 of 5

Which of the following is a complication of diabetes mellitus?

Correct Answer: A

Rationale: Gastroparesis is a complication of diabetes mellitus. It is a condition that affects the normal spontaneous movement of the muscles in the stomach, causing delayed emptying of food from the stomach into the small intestine. This can lead to symptoms such as nausea, vomiting, bloating, and poor appetite. Diabetes can damage the nerves that control the stomach muscles, resulting in gastroparesis. Managing blood sugar levels and following a proper diet can help in controlling the symptoms of gastroparesis in individuals with diabetes. Exophthalmos, hirsutism, and moon facies are not typically associated with complications of diabetes mellitus.

Question 3 of 5

Which one of the following statements is true regarding the prevalence of acromegaly?

Correct Answer: C

Rationale: Acromegaly is a rare hormonal disorder where excess growth hormone is produced, leading to the enlargement of bones and tissues. The prevalence of acromegaly is higher in men compared to women, with a ratio of about two men affected for every woman. This gender difference is believed to be due to the impact of sex hormones on the development and progression of the condition. While acromegaly can affect both men and women, men are more commonly diagnosed with the disorder.

Question 4 of 5

All the following are risk factors for the development of osteoporotic fractures except

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.

Question 5 of 5

Which cranial nerve is not involved in acromegaly?

Correct Answer: A

Rationale: Acromegaly is a disorder caused by the overproduction of growth hormone in adulthood, usually due to a pituitary tumor. The cranial nerves that may be affected in acromegaly are Cranial Nerves III, IV, VI (oculomotor, trochlear, abducens) due to compression of the optic chiasm by the expanding tumor. Cranial Nerve V (trigeminal nerve) may also be affected given its close proximity to the pituitary gland. However, Cranial Nerve VIII (vestibulocochlear nerve) is not typically involved in acromegaly.
