- C.
Destruction of thyroid tissue
- D.
Medical supression of thyroid hormone synthesis
Correct Answer(s)
A. Surgical removal of thyroid tissue
C. Destruction of thyroid tissue
D. Medical supression of thyroid hormone synthesisExplanation
Hyperthyroidism can be treated through surgical removal of thyroid tissue, destruction of thyroid tissue, or medical suppression of thyroid hormone synthesis. Surgical removal of thyroid tissue involves removing all or part of the thyroid gland to reduce hormone production. Destruction of thyroid tissue can be achieved through radioactive iodine treatment or by using medications that destroy thyroid cells. Medical suppression of thyroid hormone synthesis involves taking medications that inhibit the production of thyroid hormones. These treatments aim to reduce the excessive production of thyroid hormones and alleviate the symptoms of hyperthyroidism.Rate this question:

Levothyroxine is a Synthroid (synthetic)
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Levothyroxine is indeed a synthetic form of the hormone thyroxine, which is produced naturally by the thyroid gland. It is commonly prescribed to treat hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone. Levothyroxine works by replacing or supplementing the natural hormone in the body, helping to regulate metabolism and energy levels. Synthroid is a brand name for levothyroxine, and they are often used interchangeably. Therefore, the statement "Levothyroxine is a Synthroid (synthetic)" is true.Rate this question:

Levothyroxine is synthetic
- A.
T4
- B.
T3
- C.
TSH
- D.
TRH
Correct Answer
A. T4Explanation
Levothyroxine is a synthetic hormone that is used to replace or supplement the thyroid hormone T4 in the body. T4, also known as thyroxine, is produced by the thyroid gland and is converted into the active form T3. Levothyroxine is commonly prescribed for individuals with an underactive thyroid gland, or hypothyroidism, to help regulate their metabolism and energy levels. It is not T3, TSH, or TRH, which are all different hormones involved in the regulation of thyroid function.Rate this question:

Levothyroxine is/has
- A.
Drug of choice for hypothyroidism
- B.
Drug of choice for hyperthyroidism
- C.
A long half life
- D.
A short half life
- E.
Narrow therapeutic range
Correct Answer(s)
A. Drug of choice for hypothyroidism
C. A long half life
E. Narrow therapeutic rangeExplanation
Levothyroxine is the drug of choice for hypothyroidism because it is a synthetic form of the thyroid hormone thyroxine, which is deficient in individuals with hypothyroidism. It has a long half-life, meaning it stays in the body for a longer duration and provides a sustained release of the hormone. Additionally, levothyroxine has a narrow therapeutic range, meaning that small changes in dosage can significantly affect its effectiveness. Therefore, it is important to closely monitor and adjust the dosage to maintain optimal thyroid hormone levels in patients with hypothyroidism.Rate this question:

It is common to need medication for T3
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement suggests that it is common to need medication for T3. However, this is not true. T3 refers to triiodothyronine, which is a hormone produced by the thyroid gland. In most cases, the body is able to produce enough T3 on its own without the need for medication. Medication for T3 is typically only prescribed in cases of thyroid disorders or certain medical conditions where the body is unable to produce sufficient levels of T3. Therefore, the correct answer is False.Rate this question:

Correct Answer(s)
A. Thyrotoxicosis
B. Tachycardia
C. Angina
D. TremorsExplanation
The given answer correctly identifies the adverse effects (AEs) of Levothyroxine, which is a medication used to treat hypothyroidism. Thyrotoxicosis refers to the condition of having excessive levels of thyroid hormones in the body, which can occur as a result of taking too much Levothyroxine. This can lead to symptoms such as tachycardia (rapid heart rate), angina (chest pain), tremors, and nausea/vomiting. These symptoms are commonly associated with hyperthyroidism, which is the opposite of hypothyroidism and occurs when there is an overproduction of thyroid hormones. Constipation and dizziness are not typically associated with thyrotoxicosis.Rate this question:

- C.
6 hours before/after calcium
- D.
30-60 minutes before breakfast
- E.
2-3 hours before breakfast
- F.
Early in the morning
Correct Answer(s)
A. On an empty stomach
B. 4 hours before/ after calcium
D. 30-60 minutes before breakfast
F. Early in the morningExplanation
The best time to take Levo is on an empty stomach because taking it with food can decrease its absorption. It is also recommended to wait 4 hours before or after taking calcium supplements, as calcium can interfere with the absorption of Levo. Taking it 30-60 minutes before breakfast ensures that there is enough time for the medication to be absorbed before any other food or medications are consumed. Taking it early in the morning is also a good option as it allows for consistent timing and helps to establish a routine.Rate this question:
