Endocrinology Exam Questions Questions
Question 1 of 5
Growth hormone:
Correct Answer: D
Rationale: Growth hormone is primarily released during sleep, particularly during the first few hours of deep sleep. This release is pulsatile in nature, with the majority occurring at night. Growth hormone plays a critical role in growth, repair, and development of body tissues during periods of rest and sleep. Additionally, the secretion of growth hormone is also influenced by factors such as stress, exercise, and nutritional status.
Question 2 of 5
Which of the following are signs of acromegaly?
Correct Answer: A
Rationale: Acromegaly is a disorder characterized by excess growth hormone production, usually due to a pituitary adenoma. Signs and symptoms of acromegaly arise gradually over time due to excess growth hormone leading to tissue overgrowth.
Question 3 of 5
Which one of the following is acromegaly caused by?
Correct Answer: C
Rationale: Acromegaly is a disorder that is characterized by the overproduction of growth hormone (GH) by the pituitary gland in adults. This results in the abnormal growth of bones and tissues, leading to enlarged hands, feet, and facial features. The excess GH is usually caused by a pituitary tumor known as a somatotroph adenoma. This tumor causes the pituitary gland to produce excessive amounts of GH, which in turn leads to the symptoms associated with acromegaly. Treatment for acromegaly often involves surgical removal or reduction of the pituitary tumor, as well as medication to normalize GH levels.

Question 5 of 5
Enlargement of the bones of the hands, feet, and face due to overproduction of growth hormone is called :
Correct Answer: A
Rationale: Acromegaly is the condition characterized by the enlargement of the bones of the hands, feet, and face due to the overproduction of growth hormone in adults. This excess growth hormone typically comes from a benign tumor in the pituitary gland, leading to the gradual enlargement of these body parts. Cushing syndrome, on the other hand, is caused by prolonged exposure to high levels of cortisol and is not directly related to bone enlargement. Gigantism is the condition of excessive growth in height due to overproduction of growth hormone occurring in children before the closure of growth plates. Myxedema is a term used to describe severe hypothyroidism and is not directly associated with bone enlargement.
