Endocrinology Exam Questions Questions

Question 1 of 5

Primary hyperaldosteronism is not featured by:

Correct Answer: B

Rationale: Primary hyperaldosteronism, also known as Conn's syndrome, is characterized by excessive production of aldosterone by the adrenal glands, leading to increased sodium reabsorption and potassium excretion in the kidneys. The typical features of primary hyperaldosteronism include hypertension (often systolic), hypokalemia, metabolic alkalosis, and oedema due to sodium retention. Paraesthesia, which refers to abnormal sensations such as tingling or numbness, is not a common feature associated with primary hyperaldosteronism.

Question 2 of 5

Anti-diuretic hormone secretion is:

Correct Answer: B

Rationale: Anti-diuretic hormone (ADH), also known as vasopressin, is a hormone released by the pituitary gland in response to changes in blood osmolality, blood volume, and blood pressure. During hemorrhage (significant blood loss), the body experiences a decrease in blood volume and blood pressure. In response to this decrease in blood volume, ADH secretion is increased to help the body retain water and maintain blood pressure levels. Therefore, it is incorrect to say that ADH secretion is reduced during hemorrhage.

Question 3 of 5

All of the following are potential causes of elevated LDL , except:

Correct Answer: A

Rationale: Cirrhosis is not a potential cause of elevated LDL cholesterol levels. The liver plays a significant role in cholesterol metabolism, and liver disease like cirrhosis can actually lead to decreased levels of LDL cholesterol. Elevated LDL cholesterol levels can be caused by conditions such as hypothyroidism, nephrotic syndrome, or the use of certain medications like thiazide diuretics.

Question 4 of 5

Which age group does acromegaly most commonly affect?

Correct Answer: A

Rationale: Acromegaly most commonly affects individuals in the age group of 30-50 years. This condition is typically diagnosed in adults between these ages. Acromegaly is often caused by the overproduction of growth hormone in adults, which leads to excessive bone growth and tissue expansion. While acromegaly can develop at any age, it is more commonly seen in adults within the 30-50 age range.

Question 5 of 5

Which of the following statements best describes Hashimoto's thyroiditis?

Correct Answer: B

Rationale: Hashimoto's thyroiditis is an autoimmune disease where the immune system mistakenly attacks the thyroid gland. The antibodies produced by the immune system target the thyroglobulin in the thyroid gland, leading to its destruction over time. This results in decreased thyroid hormone production, leading to hypothyroidism. Therefore, choice B, "A destructive autoimmune disease caused by auto-reactive antibodies against thyroglobulin," best describes Hashimoto's thyroiditis.
