    Grave's disease (a type of hyperthyroidism) is prominent in...  

    • Females

    • Males

    • Children

    Correct Answer
    A. Females
    Explanation
    Grave's disease, a type of hyperthyroidism, is prominent in females. This is because the condition is believed to be an autoimmune disorder, and women are more prone to autoimmune diseases compared to men. Additionally, hormonal factors may also play a role in the higher prevalence of Grave's disease in females.

    Nervousness, weakness, increased perspiration, weight loss, and tachycardia are signs of...

    • Hypothyroidism

    • Hyperthyroidism

    Correct Answer
    A. Hyperthyroidism
    Explanation
    Nervousness, weakness, increased perspiration, weight loss, and tachycardia are all symptoms commonly associated with hyperthyroidism. In this condition, the thyroid gland produces an excessive amount of thyroid hormones, leading to an overactive metabolism. This can result in weight loss, increased heart rate (tachycardia), and other symptoms such as nervousness and weakness. Hypothyroidism, on the other hand, is characterized by an underactive thyroid gland and typically presents with different symptoms such as fatigue, weight gain, and depression.

    A radioactive iodine uptake test helps determine intrinsic thyroid function.  A thyroid scan can help distinguish etiology (such as cancer).  A TRH stimulation test helps determine thyroid and ________ function. - ProProfs

    A radioactive iodine uptake test helps determine intrinsic thyroid function.  A thyroid scan can help distinguish etiology (such as cancer).  A TRH stimulation test helps determine thyroid and ________ function.

    • Liver

    • Pituitary

    • Intestinal

    • None of the above

    Correct Answer
    A. Pituitary
    Explanation
    A TRH stimulation test helps determine thyroid and pituitary function. The pituitary gland produces and releases thyroid-stimulating hormone (TSH), which stimulates the thyroid gland to produce thyroid hormones. Therefore, by measuring the response of the thyroid gland to TRH (thyrotropin-releasing hormone), the test can assess the function of both the thyroid gland and the pituitary gland.

    Despite the availability of a wide array of thyroid hormone products, it is clear that ___________ is the treatment of choice for almost all patients with hypothyroidism. - ProProfs

    Despite the availability of a wide array of thyroid hormone products, it is clear that ___________ is the treatment of choice for almost all patients with hypothyroidism.

    • Liothyronine (Cytomel)

    • Liotrix (Thryolar)

    • Synthetic levothyroxine (LT4)

    • Desiccared Thyroid (Armour, etc)

    • None of the above

    Correct Answer
    A. Synthetic levothyroxine (LT4)
    Explanation
    Synthetic levothyroxine (LT4) is the treatment of choice for almost all patients with hypothyroidism because it is a synthetic form of the hormone thyroxine (T4) which is produced by the thyroid gland. LT4 is the most commonly prescribed thyroid hormone replacement therapy and has a consistent potency and stability, making it easier to regulate and adjust the dosage for individual patients. It also has a longer half-life compared to other thyroid hormone products, allowing for once-daily dosing and better patient compliance. Therefore, LT4 is considered the most effective and reliable treatment option for hypothyroidism.

    Agranulocytosis often presents as a sore throat. - ProProfs

    Agranulocytosis often presents as a sore throat.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Agranulocytosis is a condition characterized by a severe decrease in the number of granulocytes, a type of white blood cell. These cells play a crucial role in the body's immune response. When the number of granulocytes is significantly reduced, it weakens the immune system's ability to fight off infections. One common symptom of agranulocytosis is a sore throat, as the lack of granulocytes makes the throat more susceptible to infections. Therefore, it is true that agranulocytosis often presents as a sore throat.

    Some causes of hypothyroidism include iatrogenic causes, drugs (such as amiodarone and lithium), and this (also known as autoimmune thyroiditis)....

    • Grave's

    • Hashimoto's

    • Silent thyroiditis

    • Hypothalamic disease

    • Pituitary disease

    Correct Answer
    A. Hashimoto's
    Explanation
    Hashimoto's disease, also known as autoimmune thyroiditis, is a common cause of hypothyroidism. It is an autoimmune disorder where the immune system mistakenly attacks the thyroid gland, leading to inflammation and damage. This results in a decreased production of thyroid hormones, causing hypothyroidism. Other causes mentioned in the question, such as Grave's disease, silent thyroiditis, hypothalamic disease, and pituitary disease, are not associated with hypothyroidism.

    High TSH but low FT4 suggests... Hint:  TSH and FT4 levels going in opposite directions is usually what we expect to see, generally indicating a problem on the level of the thyroid.

    • Primary hyperthyroidism

    • Primary hypothyroidism

    • Pituitary hyperthyroidism

    • Pituitary hypothyroidism

    • Hypothalamus hypothyroidism

    Correct Answer
    A. Primary hypothyroidism
    Explanation
    High TSH but low FT4 suggests primary hypothyroidism. In primary hypothyroidism, the thyroid gland is not producing enough thyroid hormones. This leads to an increase in TSH production from the pituitary gland as it tries to stimulate the thyroid to produce more hormones. However, since the thyroid is not functioning properly, the levels of FT4, which is a measure of active thyroid hormone, remain low. This imbalance between TSH and FT4 levels indicates a problem with the thyroid gland itself, rather than the pituitary or hypothalamus.

    Which antithyroid drug has a longer half-life (5 hours)?   - ProProfs

    Which antithyroid drug has a longer half-life (5 hours)?  

    • PTU

    • Methimazole

    Correct Answer
    A. Methimazole
    Explanation
    Methimazole has a longer half-life of 5 hours compared to PTU. This means that it takes approximately 5 hours for half of the drug to be eliminated from the body. A longer half-life suggests that the drug remains in the body for a longer duration, allowing for less frequent dosing compared to PTU.

    Rate this question:

    High TSH and high FT4 indicates __________ while low TSH and low FT4 indicate ___________.   - ProProfs

    High TSH and high FT4 indicates __________ while low TSH and low FT4 indicate ___________.  

    • Pituitary hyperthyroidism, Pituitary hypothalamic

    • Primary hyperthyroidism, Primary hypothyroidism

    Correct Answer
    A. Pituitary hyperthyroidism, Pituitary hypothalamic
    Explanation
    High TSH and high FT4 levels indicate pituitary hyperthyroidism, which is a condition where the pituitary gland produces excessive amounts of thyroid-stimulating hormone (TSH). This excess TSH stimulates the thyroid gland to produce excessive amounts of thyroxine (FT4), leading to hyperthyroidism. On the other hand, low TSH and low FT4 levels indicate pituitary hypothalamic dysfunction, where the pituitary gland and hypothalamus fail to produce enough TSH and stimulate the thyroid gland adequately, resulting in primary hypothyroidism.

    If a patient has just started a new dose of levothyroxine.  When would you recommend she get her TFTs checked again? - ProProfs

    If a patient has just started a new dose of levothyroxine.  When would you recommend she get her TFTs checked again?

    • 6 hours

    • 6 days

    • 6 weeks

    • 6 months

    • I wouldn't recommend anything because I'd be too busy calling Medco.

    Correct Answer
    A. 6 weeks
    Explanation
    The correct answer is 6 weeks. Levothyroxine is a medication used to treat hypothyroidism. It takes time for the medication to reach its full effect and stabilize the thyroid hormone levels. Therefore, it is recommended to check the thyroid function tests (TFTs) after 6 weeks to assess the effectiveness of the medication and make any necessary adjustments to the dosage. Checking TFTs too soon may not provide an accurate reflection of the medication's effect, while waiting too long may delay necessary adjustments.

    What is a common adverse event that happens after a patient undergoes radioactive therapy?   - ProProfs

    What is a common adverse event that happens after a patient undergoes radioactive therapy?  

    • Nausea and pruritis

    • Hypothyroidism, mild thinning of hair, dysphagia

    • Hyperthyroidism, thickening of hair, weight loss

    • Weight gain, pruritis, cough

    • Cough, nausea, dysphagia

    Correct Answer
    A. Hypothyroidism, mild thinning of hair, dysphagia
    Explanation
    After undergoing radioactive therapy, a common adverse event that can occur is hypothyroidism, which is a condition where the thyroid gland does not produce enough thyroid hormone. This can lead to symptoms such as fatigue, weight gain, and thinning of hair. Dysphagia, which is difficulty swallowing, can also occur as a result of the therapy. These symptoms are commonly associated with the effects of radioactive therapy on the thyroid gland.

    Iodine deficiency can result in ________.

    Correct Answer
    goiters
    a goiter
    goiter
    GOITERS
    Explanation
    Iodine deficiency can result in the formation of goiters. A goiter is an enlarged thyroid gland, which can occur when the body does not have enough iodine to produce sufficient amounts of thyroid hormones. The term "goiters" is the plural form of goiter, indicating that multiple goiters can develop due to iodine deficiency.

    What drug is best for a pregnant patient with hyperthyroidism? - ProProfs

    What drug is best for a pregnant patient with hyperthyroidism?

    • PTU

    • Methimazole

    • No drugs. She should have a thyroidectomy.

    • No drugs during pregnancy. She should wait until after delivering her child to start treatment.

    Correct Answer
    A. PTU
    Explanation
    PTU (propylthiouracil) is the best drug for a pregnant patient with hyperthyroidism. Both PTU and methimazole are antithyroid drugs used to treat hyperthyroidism, but PTU is considered safer during pregnancy. Methimazole may pose a risk of birth defects, particularly in the first trimester, while PTU has a lower risk. However, in certain cases where PTU is not well-tolerated or ineffective, methimazole may be used after careful consideration of the risks and benefits. Surgery, such as thyroidectomy, is generally not recommended during pregnancy unless there are severe complications or uncontrolled hyperthyroidism. Waiting until after delivery to start treatment is also not recommended as untreated hyperthyroidism can have adverse effects on both the mother and the baby.

    The target goal for TSH levels... - ProProfs

    The target goal for TSH levels...

    • 0.5 to 5

    • 0.3 to 3

    Correct Answer
    A. 0.3 to 3
    Explanation
    The target goal for TSH levels is 0.3 to 3. This range is considered normal and indicates that the thyroid gland is functioning properly. TSH (thyroid-stimulating hormone) is produced by the pituitary gland and regulates the production of thyroid hormones. TSH levels outside of this range may indicate an underactive or overactive thyroid gland, which can lead to various health issues. Therefore, maintaining TSH levels within the range of 0.3 to 3 is important for optimal thyroid function.
