Question 1 of 5
A nurse in a clinic is reviewing the laboratory values of a client who has primary hypothyroidism. The nurse should anticipate an elevation of which of the following laboratory values?
Correct Answer: B
Rationale: In primary hypothyroidism, the thyroid gland is underactive and does not produce sufficient thyroid hormones, including Free T4.
Therefore, we would not expect an elevation of Free T4 in primary hypothyroidism; instead, its levels would typically be low or normal. Thyroid stimulating hormone (TSH) levels are elevated in primary hypothyroidism because the pituitary gland releases more TSH in an attempt to stimulate the thyroid gland to produce more thyroid hormones. This is a compensatory response to the low levels of circulating thyroid hormones, particularly thyroxine (T4). Serum T3 levels may be low or normal in primary hypothyroidism. T3 is the active form of thyroid hormone and is usually converted from T4. If T4 levels are low, T3 levels may also be affected; however, T3 levels are not the primary diagnostic marker for hypothyroidism and do not typically show elevation in this condition. Serum T4 levels are typically low in primary hypothyroidism because the thyroid gland is not producing enough of this hormone. An elevation of serum T4 would not be expected unless the patient is receiving treatment for hypothyroidism.
