The nurse is caring for a client suspected of having thyroid storm. Which laboratory test is commonly used to assess thyroid function and diagnose thyroid storm?
Complete blood count (CBC)
Serum electrolyte panel
Thyroid-stimulating hormone (TSH) level
Thyroid hormone levels (T3 and T4)
The Correct Answer is D
Measuring thyroid hormone levels, specifically triiodothyronine (T3) and thyroxine (T4), is an essential diagnostic evaluation for thyroid storm. Elevated levels of these hormones indicate excessive thyroid hormone production and are indicative of thyroid storm.
