Which is a major side effect of radioactive iodine treatment for hyperthyroidism?
TSH low,T3 & T4 elevated
TSH elevated, T3 & T4 low
TSH,T3 & T4 low
TSH, T4 elevated and T3 low
The Correct Answer is B
Choice A rationale: Elevated T3 and T4 with low TSH levels are indicative of hyperthyroidism, not a side effect of radioactive iodine treatment.
Choice B rationale: One of the expected side effects of RAI treatment for hyperthyroidism is permanent hypothyroidism (or underactive thyroid, when the thyroid does not produce enough hormones). Elevated TSH levels with low T3 and T4 are indicative of hypothyroidism.
Choice C rationale: Low TSH, T3, and T4 levels are not typical outcomes of radioactive iodine treatment; typically, the treatment leads to a decrease in T3 and T4 with increased TSH levels.
Choice D rationale: Elevated TSH and low T3 is major side effect of radioactive iodine treatment for hyperthyroidism. However, it does not cause elevated T4 levels.
