The patient's abnormalities are likely to improve with treatment using a cofactor for which process?
A) Carboxylation of prothrombin
B) Conversion of homocysteine to methionine
C) Farnesylation of ras
D) Hydroxylation of procollagen

A 45-year-old woman who has acute diverticulitis develops severe hypotension, tachypnea, and tachycardia. She subsequently develops cyanosis and hypoxemia unresponsive to oxygen therapy. X-ray films of the chest show a diffuse alveolar infiltrate. Blood culture grows Escherichia coli. A major factor in the pathogenesis of this syndrome is
A) degranulation of mast cells
B) delayed (type IV) hypersensitivity to bacterial products
C) increased surfactant production by type II pneumocytes
D) production of antibodies to alveolar basement membranes
E) release of oxygen free radicals from sequestered neutrophils

A 38-year-old woman has noticed the gradual development of a goiter. Thyroid function studies show serum thyroxine (T4) and triiodothyronine (T3) concentrations to be within the reference range. Serum concentration of thyroid-stimulating hormone is slightly increased. The serum contains a high level of antimicrosomal (antiperoxidase) antibodies, but no thyroid-stimulating hormone receptor antibodies are detected. The most likely diagnosis is
A) autoimmune (Hashimoto's) thyroiditis
B) diffuse toxic goiter (Graves' disease)
C) primary atrophy of the thyroid gland
D) Riedel's struma
E) subacute thyroiditis
