A nurse in a clinic is reviewing the laboratory values of a client who has primary hypothyroidism.
Which of the following laboratory values should the nurse anticipate an elevation of?
Free T4
Serum T3
Serum T4
Thyroid stimulating hormone (TSH)
The Correct Answer is D
A. In primary hypothyroidism, the thyroid gland fails to produce sufficient thyroid hormone.
Consequently, free T4 levels are typically decreased.
B. Although serum T3 levels may also decrease in primary hypothyroidism due to impaired thyroid function, TSH is the primary marker used for diagnosis and monitoring.
C. Similarly, serum T4 levels may decrease in primary hypothyroidism due to decreased synthesis by the thyroid gland.
D. In primary hypothyroidism, the anterior pituitary gland releases more TSH to stimulate the thyroid gland to produce thyroid hormones. Therefore, elevated TSH levels are characteristic of primary hypothyroidism.
