The nurse is reviewing the results of a client's laboratory studies to find the level of an important chemical that must be available to assist in the synthesis of thyroid hormones, or:

1. cortisol.
2. iodide.
3. calcitonin.
4. iodine.

Question 2

The nurse would anticipate elevated levels of circulating T3 and T4 in the client with:

1. leukopenia.
2. thrombocytopenia.
3. hypoalbuminemia.
4. hemolytic anemia.

Answer to Question 1

Correct Answer: 4
Rationale 1: Cortisol does not aid in the synthesis of thyroid hormones.
Rationale 2: Iodide does not aid in the synthesis of thyroid hormones.
Rationale 3: Calcitonin does not aid in the synthesis of thyroid hormones.
Rationale 4: Iodine is involved in the synthesis of thyroid hormones.
Global Rationale: Iodine is involved in the synthesis of thyroid hormones. Cortisol, iodide, and calcitonin do not aid in the synthesis of thyroid hormones.

Answer to Question 2

Correct Answer: 3
Rationale 1: A client with leukopenia would have normal levels of circulating T3 and T4.
Rationale 2: A client with thrombocytopenia would have normal levels of circulating T3 and T4.
Rationale 3: A client with hypoalbuminemia would have excessive levels of circulating T3 and T4. Any condition that causes decreased amounts of plasma proteins, such as protein malnutrition, can lead to a larger percentage of free thyroid hormone, with subsequent symptoms of hyperthyroidism.
Rationale 4: A client with hemolytic anemia would have normal levels of circulating T3 and T4.
Global Rationale: A client with hypoalbuminemia would have excessive levels of circulating T3 and T4. Any condition that causes decreased amounts of plasma proteins, such as protein malnutrition, can lead to a larger percentage of free thyroid hormone, with subsequent symptoms of hyperthyroidism. This is not the case in patients with leukopenia, thrombocytopenia, or hemolytic anemia.
