The 40-year-old client is receiving levothyroxine for treatment of hypothyroidism. Which serum laboratory results should lead the nurse to conclude that the client's dose is adequate?

  • A. Thyroid-stimulating hormone and cortisol
  • B. Thyroid-stimulating hormone and free T4
  • C. Triiodothyronine (T3) and free thyroxine (T4)
  • D. White blood cells, glucose, and potassium
Correct Answer: B

Rationale: A: Cortisol levels are used to evaluate adrenal and not thyroid function. B: Restoration of normal laboratory values for TSH and free T4 indicates that the dose of levothyroxine (Synthroid) is therapeutic. C: T3 is used to evaluate the effectiveness of liothyronine and propylthiouracil, used in the treatment of thyroid disorders. D: The WBC count is used to determine if the client has an infection. Evaluation of serum glucose and potassium levels is unrelated to the use of levothyroxine.
