question 17 of 20
a health care provider suspects that a thyroid nodule may be malignant. the nurse knows to prepare information for the client based on the usual test that will be ordered to establish a diagnosis. what is that test?

• ultrasound of the thyroid gland
• fine - needle biopsy of the thyroid gland
• free t4 analysis
• serum immunoassay for tsh

Explanation:

To diagnose if a thyroid nodule is malignant, a tissue sample is needed. Fine - needle biopsy of the thyroid gland is used to obtain thyroid tissue for pathological examination to determine malignancy. Ultrasound is for imaging, not for definitive diagnosis of malignancy. Free T4 analysis and serum immunoassay for TSH are for assessing thyroid function, not for diagnosing malignancy.

Answer:

B. Fine - needle biopsy of the thyroid gland
