A goiter is an enlargement or hypertrophy of which gland?
Thyroid.
Posterior pituitary.
Adrenal.
Anterior pituitary.
The Correct Answer is A
Choice A rationale:
A goiter refers to the enlargement or hypertrophy of the thyroid gland. This can occur due to various reasons, such as iodine deficiency, autoimmune disorders like Hashimoto's thyroiditis, or Graves' disease (which is associated with hyperthyroidism). The thyroid gland produces hormones that regulate metabolism and growth, and when it becomes enlarged, it can lead to visible swelling in the neck.
Choice B rationale:
The posterior pituitary gland is responsible for the release of hormones like vasopressin (antidiuretic hormone) and oxytocin. A goiter is not associated with the posterior pituitary gland. Issues with the posterior pituitary can lead to problems with water balance and uterine contractions, but not thyroid enlargement.
Choice C rationale:
The adrenal glands are responsible for producing hormones like cortisol and adrenaline. While adrenal disorders can lead to various hormonal imbalances, a goiter is not related to adrenal gland function. Adrenal issues might cause symptoms like fatigue, weight changes, and blood pressure irregularities.
Choice D rationale:
The anterior pituitary gland produces hormones that regulate the functions of other endocrine glands, including the thyroid gland. However, a goiter is not directly associated with the anterior pituitary. The anterior pituitary's malfunction can result in disorders like growth hormone deficiency or Cushing's disease, but not thyroid enlargement.

Correct Answer is A
Explanation
The correct answer is Choice A: Surgical removal of the affected section of bowel.
Choice A rationale:
Surgical removal of the affected section of bowel is the primary therapeutic management for most children with Hirschsprung's disease. Hirschsprung's disease is a congenital condition where there is a lack of nerve cells in a segment of the colon, leading to obstruction and dilation of the bowel. Surgical resection of the affected segment and reconnection of healthy bowel portions is the standard treatment to alleviate the obstruction and restore normal bowel function.
Choice B rationale:
Daily enemas might be used in some cases to manage symptoms temporarily, but they are not the primary therapeutic management for Hirschsprung's disease. Surgery is the mainstay of treatment.
Choice C rationale:
Permanent colostomy might be considered if the affected portion of bowel is extensive and cannot be safely reconnected after resection, but it's not the primary option for most children with Hirschsprung's disease.
Choice D rationale:
A low-fiber diet is not a therapeutic management for Hirschsprung's disease. Surgical intervention is necessary to address the underlying cause of obstruction, and diet modifications alone wouldn't resolve the condition.
Correct Answer is C
Explanation
The correct answer is choice C. Sparse hair.
Choice A rationale:
Sleepiness is not a typical symptom of hypothyroidism. Hypothyroidism, a condition where the thyroid gland doesn't produce enough thyroid hormone, leads to a slower metabolism which can cause fatigue, but not necessarily sleepiness.
Choice B rationale:
Weight loss is not associated with hypothyroidism. In fact, weight gain is a common symptom due to the reduced metabolic rate caused by insufficient thyroid hormone levels.
Choice C rationale:
Sparse hair is a characteristic symptom of hypothyroidism. The thyroid hormones play a crucial role in the growth and maintenance of hair follicles. In hypothyroidism, hair can become brittle, thin, and sparse.
Choice D rationale:
Diarrhea is not a typical symptom of hypothyroidism. Constipation, on the other hand, is more commonly associated with this condition due to the slowed digestive processes caused by low thyroid hormone levels.
Choice E rationale:
Puffiness around the eyes is not typically associated with hypothyroidism. However, it is a symptom of another thyroid disorder known as Graves' disease, which is characterized by hyperthyroidism (overactive thyroid).
