Answer to Question 1
Correct Answer: 1
Rationale 1: TSH is the preferred laboratory value for monitoring the progression of thyroid disease.
Rationale 2: T3 is not the preferred laboratory value for monitoring the progression of thyroid disease.
Rationale 3: I-131 is not the preferred laboratory value for monitoring the progression of thyroid disease.
Rationale 4: T4 is not the preferred laboratory value for monitoring the progression of thyroid disease.
Global Rationale: TSH is the preferred laboratory value for monitoring the progression of thyroid disease. Levels of T3, T4, an iodine are not as indicative of progression of thyroid disease. T3 and T4 are affected by protein level.
Answer to Question 2
Correct Answer: 1,2,3,5
Rationale 1: The anterior pituitary's metabolic rate is not stimulated by thyroid hormones.
Rationale 2: The lung's metabolic rate is not stimulated by thyroid hormones.
Rationale 3: The brain's metabolic rate is not stimulated by thyroid hormones.
Rationale 4: The kidney's metabolic rate is stimulated by thyroid hormones.
Rationale 5: The testes' metabolic rate is not stimulated by thyroid hormones.
Global Rationale: Thyroid hormone stimulates the basal metabolic rate of all tissues except the brain, anterior pituitary, spleen, lymph nodes, testes, and lungs. The kidney's metabolic rate is stimulated by thyroid hormones.
