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","B","D"]
Explanation
The correct answers are choices A, B, and D.
Choice A rationale:
Decreased urinary output can be a sign of heart failure, especially in infants. In heart failure, the heart's ability to pump effectively can lead to decreased blood flow to the kidneys, resulting in decreased urine production.
Choice B rationale:
Sweating (inappropriate) is a symptom of heart failure in infants. Infants with heart failure might sweat excessively, especially while feeding or crying, due to the effort required by the heart to pump blood effectively.
Choice C rationale:
Warm flushed extremities are not typically associated with heart failure in infants. In heart failure, extremities might actually become cool and pale due to poor circulation.
Choice D rationale:
Anorexia, or a lack of appetite, is a common sign in infants with heart failure. The increased effort required for feeding due to compromised cardiac function can lead to poor feeding and decreased appetite.
Choice E rationale:
Weight loss can occur in infants with heart failure due to inadequate caloric intake, difficulty with feeding, and increased metabolic demands associated with heart failure. However, it's not as specific a sign as decreased urinary output, sweating, and anorexia.
