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:
Cloudiness in the lens of the eyes is the hallmark symptom of cataracts. Cataracts cause the lens to become opaque, leading to blurred vision and difficulty seeing clearly. This cloudiness can make it challenging to perform everyday tasks and is the most indicative sign of cataracts.
Choice B Reason:
Double vision in one eye can occur with cataracts, but it is not the most indicative symptom. While cataracts can cause visual disturbances, the primary symptom is the cloudiness of the lens, which directly impacts vision clarity.
Choice C Reason:
Eye pain and redness are not typical symptoms of cataracts. These symptoms are more commonly associated with other eye conditions such as infections or glaucoma. Cataracts primarily cause visual disturbances without significant pain or redness.
Choice D Reason:
Sudden loss of vision is not characteristic of cataracts. Cataracts develop gradually over time, leading to a slow progression of vision impairment. Sudden vision loss is more likely to be associated with acute conditions such as retinal detachment or vascular occlusions.
Correct Answer is B
Explanation
Choice A Reason:
Advising the patient to increase their screen time to exercise their eye muscles is not appropriate for managing macular degeneration. Increased screen time can cause eye strain and does not benefit the condition. Instead, patients should be encouraged to engage in activities that do not exacerbate eye strain.
Choice B Reason:
Encouraging the patient to quit smoking is a crucial intervention for managing macular degeneration. Smoking is a significant risk factor for the progression of macular degeneration. Quitting smoking can help slow the progression of the disease and improve overall eye health. This intervention addresses a modifiable risk factor and can have a positive impact on the patient’s condition.
Choice C Reason:
Suggesting the patient avoid all physical activities to prevent further eye damage is not necessary for managing macular degeneration. Physical activity is important for overall health and does not directly impact the progression of macular degeneration. Patients should be encouraged to maintain a healthy lifestyle, including regular physical activity.
Choice D Reason:
Informing the patient to reduce their water intake to prevent fluid accumulation in the eyes is not relevant for managing macular degeneration. Adequate hydration is important for overall health, and there is no evidence to suggest that reducing water intake will benefit patients with macular degeneration. This advice could potentially lead to dehydration and other health issues.
