Pharmacology II Exam: Thyroid Antagonists Quiz!

Explanation
The correct answer is "inhibits" because inhibiting the production of thyroid hormones means to reduce or prevent their synthesis or release. This action typically takes 2-3 weeks to have a therapeutic effect, indicating that it takes time for the inhibition to take full effect and decrease the levels of thyroid hormones in the body.

Explanation
Prior to thyroid surgery, the treatment of hyperthyroidism involves decreasing the vascularity of the gland. This is important to minimize bleeding during the surgery. By reducing the blood flow to the gland, the risk of excessive bleeding is reduced, making the procedure safer. Additionally, post-operatively, decreasing bleeding is crucial for proper healing and recovery.

Explanation
Glipizide (Glucatrol) is not a medication pertaining to Thyroid Antagonists. Glipizide is actually an oral medication used to treat type 2 diabetes by stimulating the release of insulin from the pancreas. Thyroid Antagonists are medications used to inhibit the production or release of thyroid hormones, and the other options listed (methimazole, radioactive iodine, and propylthiouracil) are all examples of such medications.

Explanation
Fatigue is not an adverse effect because it is a common symptom that can be caused by various factors such as lack of sleep, stress, or physical exertion. It is not typically associated with the use of medications or the occurrence of adverse reactions. Adverse effects, on the other hand, refer to unwanted or harmful reactions that can occur as a result of taking a medication or undergoing a medical treatment. Examples of adverse effects mentioned in the question include sore throat, bone marrow depression, and cough, which are known side effects of certain medications or medical conditions.

Explanation
Caution should be taken when using in patients over the age of 40. This implies that there may be potential risks or complications associated with the use of whatever treatment or medication is being referred to. It is important to closely monitor and consider the specific needs and potential vulnerabilities of patients over this age threshold to ensure their safety and well-being during the course of their treatment.

Explanation
PTU, or propylthiouracil, is a medication commonly used to treat hyperthyroidism. However, it has been associated with certain side effects. In children, PTU can potentially cause brain and neurological damage. This is because the medication can cross the blood-brain barrier and affect the central nervous system. Additionally, PTU has been linked to an increased risk of liver damage in children. In the elderly, PTU can cause congestive heart failure (CHF), a condition where the heart is unable to pump blood effectively. This is an important precaution to consider when prescribing PTU to older individuals.

Explanation
PTU (propylthiouracil) is a medication used to treat hyperthyroidism, while lithium and iodine medications are used to treat various conditions including bipolar disorder and thyroid disorders. When PTU is combined with lithium or iodine medications, it can lead to an addictive effect. This means that the combination of these medications may increase the risk of dependence or addiction, potentially leading to harmful consequences. It is important for healthcare professionals to monitor and manage these interactions to ensure the safe and effective use of these medications.

Explanation
Checking for allergy to iodine is a nursing assessment pertaining to thyroid antagonists because iodine is commonly used in medications used to treat thyroid conditions. It is important to check for any allergies to iodine before administering these medications to ensure patient safety and prevent any adverse reactions.

Explanation
The question asks for something that does not pertain to the client's education. The options "weighing self twice a week," "timing of med," and "how to take iodine solutions" all relate to the client's health and medication education. However, the "time of sleep at night" does not directly relate to the client's education, but rather to their sleep habits.
