A nurse in a clinic is reviewing the laboratory values of a patient who has primary hypothyroidism. The nurse should anticipate an elevation in which of the following laboratory values?
Free T4.
Serum T3.
Thyroid stimulating hormone (TSH).
Serum calcium.
The Correct Answer is C
Choice A rationale
Free T4 levels are typically low in primary hypothyroidism, not elevated.
Choice B rationale
Serum T3 levels are also typically low in primary hypothyroidism.
Choice C rationale
In primary hypothyroidism, the thyroid gland is not producing enough thyroid hormone, leading to an elevated TSH level as the pituitary gland tries to stimulate more hormone production.
Choice D rationale
Serum calcium levels are not directly affected by primary hypothyroidism.
