A 45-year-old female patient presents with symptoms of weight loss, palpitations, and heat intolerance. Laboratory results reveal elevated T3 and T4 levels and suppressed TSH levels. Considering her clinical presentation and lab results, which of the following treatments is most appropriate for managing her hyperthyroidism?
Methimazole.
Levothyroxine.
Radioactive iodine.
Propranolol.
The Correct Answer is C
Choice A Reason:
Methimazole is an antithyroid medication that inhibits the synthesis of thyroid hormones. It is commonly used to manage hyperthyroidism, especially in patients who are not candidates for radioactive iodine therapy or surgery. Methimazole is effective in reducing thyroid hormone levels and controlling symptoms, but it requires long-term use and regular monitoring of thyroid function tests.
Choice B Reason:
Levothyroxine is a synthetic form of thyroxine (T4) used to treat hypothyroidism, not hyperthyroidism. Administering levothyroxine to a patient with hyperthyroidism would exacerbate the condition by increasing thyroid hormone levels. Therefore, it is not an appropriate treatment for managing hyperthyroidism.
Choice C Reason:
Radioactive iodine is a widely used treatment for hyperthyroidism. It works by destroying overactive thyroid cells, thereby reducing the production of thyroid hormones. This treatment is particularly effective for patients with Graves’ disease, toxic multinodular goiter, or toxic adenoma. Radioactive iodine is a definitive treatment that can lead to a permanent resolution of hyperthyroidism, although it may result in hypothyroidism, which can be managed with levothyroxine.
Choice D Reason:
Propranolol is a beta-blocker that helps manage the symptoms of hyperthyroidism, such as palpitations, tremors, and anxiety. While it is useful for symptomatic relief, it does not address the underlying cause of hyperthyroidism. Propranolol is often used in conjunction with other treatments, such as antithyroid medications or radioactive iodine, to provide immediate symptom control.

Correct Answer is A
Explanation
Choice A Reason:
Testing blood glucose levels every 6 hours during illness is crucial for managing type 1 diabetes. Illness can cause blood glucose levels to fluctuate unpredictably, and frequent monitoring helps in making timely adjustments to insulin doses and dietary intake. This practice helps prevent both hyperglycemia and hypoglycemia, ensuring better overall control of diabetes during periods of illness.
Choice B Reason:
Administering the usual daily dose of insulin is important even during illness. Skipping insulin doses can lead to dangerously high blood glucose levels and increase the risk of diabetic ketoacidosis (DKA). It is essential to continue taking insulin as prescribed and to consult with a healthcare provider if any adjustments are needed based on blood glucose readings.
Choice C Reason:
Limiting juices, soda, and gelatin is not typically recommended during illness for patients with type 1 diabetes. These items can be useful for maintaining hydration and providing quick sources of carbohydrates if the patient is unable to eat solid foods. Instead of limiting these items, it is more important to monitor carbohydrate intake and adjust insulin doses accordingly.
Choice D Reason:
Reporting a blood glucose level greater than 300 is critical for preventing complications. High blood glucose levels can indicate the onset of DKA, a serious condition that requires immediate medical attention. Promptly reporting elevated blood glucose levels allows for timely intervention and management to prevent severe complications.
Correct Answer is B
Explanation
Choice A Reason:
Night blindness, or difficulty seeing in low light, is not a primary symptom of macular degeneration. This condition primarily affects the macula, the central part of the retina responsible for sharp, central vision. Night blindness is more commonly associated with conditions like retinitis pigmentosa or vitamin A deficiency.
Choice B Reason:
Central vision loss is the hallmark of macular degeneration. This condition leads to the deterioration of the macula, causing blurred or lost central vision while peripheral vision remains intact. Patients often report difficulty reading, recognizing faces, and performing tasks that require fine visual detail3.
Choice C Reason:
Peripheral vision loss is not typically associated with macular degeneration. This condition affects the central part of the retina, leaving peripheral vision largely unaffected. Peripheral vision loss is more commonly seen in conditions like glaucoma.
Choice D Reason:
Double vision, or diplopia, is not a characteristic symptom of macular degeneration. This condition affects the clarity of central vision but does not typically cause double vision. Double vision can result from issues with the eye muscles or nerves, such as in cases of strabismus or cranial nerve palsies.
