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 C
Explanation
Choice A reason: Fluticasone, an inhaled steroid, treats asthma inflammation safely in heart failure, reducing airway reactivity without cardiac impact, so no clarification is needed.
Choice B reason: Captopril, an ACE inhibitor, reduces preload in heart failure, safe with asthma as it doesn’t affect airways, aligning with standard therapy.
Choice C reason: Carvedilol, a non-selective beta-blocker, treats heart failure but risks bronchospasm in asthma by blocking beta-2 receptors, requiring clarification for safety.
Choice D reason: Isosorbide dinitrate dilates vessels in heart failure, reducing workload, with no asthma contraindication, making it appropriate without needing clarification.
Correct Answer is A
Explanation
Choice A reason: Donepezil treats Alzheimer’s by inhibiting cholinesterase, boosting acetylcholine for cognition. Lupus, an autoimmune disease, doesn’t involve dementia primarily, so this drug lacks relevance to its management.
Choice B reason: Prednisone, a corticosteroid, suppresses inflammation and immune response in lupus, reducing joint pain and organ damage from autoantibody activity, making it a standard treatment.
Choice C reason: Hydroxychloroquine modulates immunity and reduces lupus flares by stabilizing lysosomes and decreasing autoantibody production, directly addressing its autoimmune pathology.
Choice D reason: Methotrexate, an immunosuppressant, inhibits folate metabolism, curbing immune cell proliferation in lupus, effectively managing severe symptoms like arthritis or organ involvement.
