A goiter is characterized by which of the following?
Fever of 103 degrees
An enlarged thyroid
Fibrotic tissue in the arterioles
Deposits of glycosaminoglycans in the skin
The Correct Answer is B
Choice A reason: Fever of 103°F may occur in thyroid storm, not goiter, which is simply thyroid enlargement without systemic hypermetabolism or infection necessarily.
Choice B reason: Goiter is defined by thyroid gland enlargement, often from iodine deficiency or hyperplasia, palpable as a neck mass, the core characteristic here.
Choice C reason: Fibrotic tissue in arterioles relates to vascular diseases, not goiter, which involves thyroid tissue growth, not arterial structural changes.
Choice D reason: Glycosaminoglycan deposits occur in myxedema (hypothyroidism), not goiter, which is enlargement alone, not skin or connective tissue alteration.

Correct Answer is ["A","B","D"]
Explanation
Choice A reason: Butterfly rash, a malar erythema, is a classic SLE sign, triggered by photosensitivity and immune complex deposition in skin, reflecting systemic inflammation.
Choice B reason: Pleural effusions occur in SLE from serositis, where autoantibodies inflame pleura, causing fluid buildup, a common thoracic manifestation of the disease.
Choice C reason: Elevated ammonia levels relate to liver failure, not SLE, which affects kidneys and joints, not ammonia metabolism, making this unrelated.
Choice D reason: Pericarditis in SLE results from immune-mediated inflammation of the pericardium, causing chest pain and effusion, a frequent cardiac feature.
Choice E reason: Esophageal varices stem from portal hypertension in cirrhosis, not SLE, which targets connective tissues, not liver vasculature directly.
Correct Answer is D
Explanation
Choice A reason: Levothyroxine takes weeks to normalize metabolism in hypothyroidism as T4 converts to T3 gradually, so immediate symptom relief isn’t accurate or expected.
Choice B reason: Levothyroxine supplements, not decreases, thyroxine in hypothyroidism. Decreasing overproduction applies to hyperthyroidism treatments like antithyroid drugs, not this condition.
Choice C reason: Hypothyroidism requires lifelong levothyroxine since the thyroid can’t produce hormone. Stopping when symptoms resolve risks recurrence, making this advice incorrect.
Choice D reason: Excess levothyroxine mimics hyperthyroidism, causing tremors, nervousness, and insomnia from overstimulated metabolism, correctly indicating a need for dose adjustment.
