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 C
Explanation
The correct answer is choice C. They may lie to meet expectations set by others that they have been unable to attain.
Choice A rationale:
Lying resulting from the inability to distinguish between fact and fantasy is more characteristic of younger children and might not be as applicable to the 8 to 10-year-old age group.
Choice B rationale:
While cheating during games might be a behavior observed in children, it doesn't specifically address the characteristic of dishonesty outlined in the question for this age group.
Choice C rationale:
Children aged 8 to 10 years may lie to meet expectations set by others that they have been unable to attain. This is a manifestation of social pressure and the desire to avoid disappointing others or facing consequences for not meeting perceived expectations.
Choice D rationale:
Stealing due to a limited sense of property rights might apply more to younger children who are still developing their understanding of ownership and boundaries.
Correct Answer is B
Explanation
The correct answer is choice B. Reduce gastric acid production.
Choice A rationale:
Preventing reflux is not the primary purpose of prescribing a histamine receptor antagonist. Histamine receptor antagonists work by reducing gastric acid production, which in turn can help alleviate symptoms of gastroesophageal reflux disease (GERD). They do not directly prevent the physical reflux of stomach contents into the esophagus.
Choice B rationale:
The primary purpose of prescribing a histamine receptor antagonist for an infant diagnosed with gastroesophageal reflux is to reduce gastric acid production. Histamine stimulates acid secretion in the stomach, and these medications (e.g., ranitidine, famotidine) block histamine receptors on stomach cells, leading to decreased acid secretion. This helps reduce the acidity of stomach contents that could contribute to esophageal irritation in GERD.
Choice C rationale:
Preventing hematemesis (vomiting blood) is not a primary action of histamine receptor antagonists. While reducing gastric acid production might indirectly help prevent complications such as bleeding due to irritation and inflammation of the esophagus, it's not the main purpose of these medications.
Choice D rationale:
Increasing gastric acid production is the opposite of the intended effect of histamine receptor antagonists. These medications are specifically used to decrease gastric acid production and provide relief from conditions where excess acid is causing problems, such as GERD.
