The nurse is reviewing the diagnostic evaluation for a client suspected of having a goiter. Which laboratory test is commonly used to assess thyroid function and determine if the goiter is associated with hyperthyroidism or hypothyroidism?
Complete blood count (CBC)
Blood glucose level
Thyroid-stimulating hormone (TSH) level
Serum creatinine level
The Correct Answer is C
Thyroid-stimulating hormone (TSH) is a hormone produced by the pituitary gland that stimulates the thyroid gland to produce thyroid hormones. An elevated TSH level indicates hypothyroidism, while a low TSH level indicates hyperthyroidism, both of which can be associated with a goiter.
Incorrect choices:
a. Complete blood count (CBC) assesses various components of blood but is not directly related to thyroid function or goiter diagnosis.
b. Blood glucose level is used to diagnose diabetes mellitus and is not directly related to goiter diagnosis.
d. Serum creatinine level is used to assess kidney function and is not directly related to thyroid function or goiter diagnosis.
