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
Choice A rationale:
Calcium carbonate is often given with meals to individuals with chronic renal disease, especially those on dialysis. One of the primary purposes is to bind dietary phosphorus in the gastrointestinal tract. In chronic renal disease, the kidneys are less effective at filtering out excess phosphorus from the blood, leading to elevated phosphorus levels (hyperphosphatemia). Elevated phosphorus levels can contribute to bone and mineral disorders in these patients. Calcium carbonate forms insoluble calcium phosphate complexes with dietary phosphorus, preventing its absorption and facilitating its elimination from the body through the feces.
Choice B rationale:
While calcium carbonate can interact with fat-soluble vitamins like vitamin D, the primary reason for administering it to individuals with chronic renal disease is to manage phosphorus levels. Calcium carbonate can bind phosphorus and prevent its absorption, which is particularly important for patients with compromised kidney function.
Choice C rationale:
Stimulating appetite is not a primary purpose of administering calcium carbonate to children with chronic renal disease. The main focus is on managing phosphorus levels and preventing complications associated with hyperphosphatemia.
Choice D rationale:
Preventing vomiting is not a primary purpose of giving calcium carbonate to children with chronic renal disease. Calcium carbonate is typically used to manage phosphorus levels and complications related to hyperphosphatemia in this population.
Correct Answer is C
Explanation
The correct answer is choice C.
Choice C rationale:
Placing the avulsed tooth in cold milk is the most suitable medium for transporting it to the dentist. Cold milk helps preserve the viability of the tooth's cells and tissues, which is crucial for successful reimplantation. The temperature and composition of cold milk provide a suitable environment to prevent cell damage.
Choice A rationale:
Placing the tooth in a dry, clean jar is not recommended. A dry environment can cause the tooth's cells to dry out and become nonviable, making reimplantation less successful.
Choice B rationale:
Warm salt water is not the optimal choice for transporting an avulsed tooth. Warm water can cause damage to the tooth's cells, and salt water may not provide the necessary conditions to maintain the tooth's viability.
Choice D rationale:
Placing the tooth in cold water might seem logical, but it is not as effective as cold milk. Cold water lacks the protective properties and nutrients that milk provides, potentially leading to a higher risk of cell damage in the avulsed tooth.
