    What is the swelling or enlargement of the thyroid gland?

    • A.

      Benign

    • B.

      Goiter

    • C.

      Nodule

    • D.

      Cyst

    Correct Answer
    B. Goiter
    Explanation
    Goiter is the swelling or enlargement of the thyroid gland. It is usually caused by a lack of iodine in the diet, which leads to an imbalance in the production of thyroid hormones. This imbalance triggers the thyroid gland to enlarge in an attempt to compensate for the deficiency. Goiter can also be caused by other factors such as certain medications, autoimmune diseases, or genetic factors. It is important to note that goiter can be either benign or malignant, but in this context, the term "goiter" refers to the non-cancerous enlargement of the thyroid gland.

    Rate this question:

  • 11. 

     It is an autoimmune disease affecting the thryoid, particularly in women. It is characterized by, among other things, a hyperthyroid phase early, while the gland is "inflamed" and then a longer hypothyroid state once the gland is "burnt out".

    • A.

      Hashimoto's disease

    • B.

      Levothyroxide

    • C.

      Cancer of or surrounding the thyroid gland

    • D.

      Cornoran's disease

    Correct Answer
    A. Hashimoto's disease
    Explanation
    Hashimoto's disease is an autoimmune disease that primarily affects the thyroid gland, especially in women. It is characterized by two phases - a hyperthyroid phase in the early stages when the gland is inflamed, followed by a longer hypothyroid phase once the gland is burnt out. This means that initially, the thyroid gland produces an excessive amount of thyroid hormones, leading to hyperthyroidism symptoms. However, over time, the gland becomes damaged and unable to produce enough hormones, resulting in hypothyroidism symptoms. Levothyroxine is commonly prescribed to manage the hypothyroid phase of Hashimoto's disease.

    Which of these is not a corticosteroid

    • A.

      Glucocorticoids

    • B.

      glucocorticoids

    • C.

      Mineralcorticoids

    • D.

      Thyrocalcitonin

    Correct Answer
    D. Thyrocalcitonin
    Explanation
    Thyrocalcitonin is not a corticosteroid because it is a hormone produced by the thyroid gland that helps regulate calcium levels in the body. Corticosteroids, on the other hand, are a class of steroid hormones produced by the adrenal cortex that have anti-inflammatory and immunosuppressive effects. Examples of corticosteroids include glucocorticoids and mineralocorticoids.

    What disease of the endocrine system consists of weakness, fatigue, anorexia, weight loss, hyperpigmentation, and decreased blood pressure

    • A.

      Addison's disease

    • B.

      Turner's syndrome

    • C.

      Cushing's syndrome

    • D.

      Hyperthyroidism

    Correct Answer
    A. Addison's disease
    Explanation
    Addison's disease is an endocrine disorder characterized by the insufficient production of adrenal hormones. The symptoms mentioned in the question, such as weakness, fatigue, anorexia, weight loss, hyperpigmentation, and decreased blood pressure, are commonly associated with this condition. Addison's disease occurs when the adrenal glands are damaged or destroyed, leading to a deficiency in cortisol and aldosterone production. This deficiency results in the symptoms mentioned, along with other potential complications. Turner's syndrome, Cushing's syndrome, and hyperthyroidism do not typically present with the specific combination of symptoms mentioned in the question.

    Which of these is not an endocrine gland

    • A.

      Colon

    • B.

      Thyroid

    • C.

      Pancreas

    • D.

      Adrenal

    Correct Answer
    A. Colon
    Explanation
    The colon is not an endocrine gland because it does not produce hormones that are released into the bloodstream. Instead, the colon is part of the digestive system and is responsible for absorbing water and electrolytes from undigested food, forming and storing feces, and eliminating waste from the body. Endocrine glands, such as the thyroid, pancreas, and adrenal glands, produce hormones that regulate various bodily functions and are released directly into the bloodstream.

    • D.

      Mood swings, heavy periods and loss of hair

    Correct Answer
    B. Sweating, racing heart, fast pulse, losing weight and tremor
    Explanation
    The symptoms described in the answer, sweating, racing heart, fast pulse, losing weight, and tremor, are commonly associated with hyperthyroidism. Hyperthyroidism is a condition in which the thyroid gland produces an excessive amount of thyroid hormone, leading to an increased metabolic rate. This can result in symptoms such as excessive sweating, a rapid heart rate, weight loss, and tremors. Therefore, if someone is experiencing these symptoms, it is likely that they are suffering from hyperthyroidism.

    Rate this question:

  • 25. 

    Which hormones are measured when a thyroid blood test has been requested

    • A.

      V3, V6, TOT

    • B.

      Cortisol

    • C.

      TSH, FT4, FT3

    • D.

      FSH

    Correct Answer
    C. TSH, FT4, FT3
    Explanation
    When a thyroid blood test is requested, the hormones that are typically measured are TSH (thyroid-stimulating hormone), FT4 (free thyroxine), and FT3 (free triiodothyronine). TSH is produced by the pituitary gland and stimulates the thyroid gland to produce and release thyroid hormones. FT4 and FT3 are the active forms of thyroid hormones that regulate metabolism and energy levels in the body. Measuring these hormones helps to assess the functioning of the thyroid gland and diagnose any thyroid disorders.

    Rate this question:

  • 26. 

    Is thyrotoxicosis a disease which can be caused by the overstimulation of the thyroid gland  

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Thyrotoxicosis is a condition characterized by excessive levels of thyroid hormones in the body, which can be caused by the overstimulation of the thyroid gland. This overstimulation can occur due to various reasons such as Graves' disease, toxic multinodular goiter, or excessive intake of thyroid hormone medications. The excessive production of thyroid hormones leads to symptoms such as weight loss, increased heart rate, tremors, and anxiety. Therefore, it is correct to say that thyrotoxicosis can be caused by the overstimulation of the thyroid gland.

  • 27. 

    People with DM2 cannot use insulin efficiently because their pancreas can no longer produce insulin

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false. People with DM2 can still produce insulin, but their bodies are unable to use it effectively. This condition is known as insulin resistance. As a result, the pancreas may even produce more insulin to compensate for the resistance, but it is still not enough to maintain normal blood sugar levels.

    Rate this question:

  • 28. 

    What gland in the body is insulin secreted from

    • A.

      Adrenal

      Gallbladder

    • C.

      Pancreas

    • D.

      Thyroid

    Correct Answer
    C. Pancreas
    Explanation
    Insulin is a hormone that regulates blood sugar levels in the body. It is secreted from the pancreas, specifically from the beta cells located in the islets of Langerhans. The pancreas plays a crucial role in the endocrine system by producing insulin and releasing it into the bloodstream in response to high blood sugar levels. Insulin helps cells in the body absorb glucose from the bloodstream, thus lowering blood sugar levels and maintaining normal glucose metabolism.

      Glycogen

    • B.

      Proteins

    • C.

      Glucagon

    • D.

      Insulin

    Correct Answer
    D. Insulin
    Explanation
    Insulin is the correct answer because it is a hormone that is required to decrease blood glucose levels. Insulin is produced by the pancreas and helps regulate the amount of glucose in the blood by allowing it to be taken up by cells for energy or storage. It promotes the conversion of glucose into glycogen, which is stored in the liver and muscles. This process helps to lower blood glucose levels and maintain them within a normal range.
