Grace has been feeling unusually energetic and has noticed an increase in her metabolism. After visiting her doctor, she learns that she has a pituitary tumor that is secreting excess TSH. What is the most likely thyroid response to this condition?
Reduced thyroid hormone synthesis
Increased T3 and T4 production
Immediate thyroid gland atrophy
Unchanged iodide organification
