Ati lpn med surg endocrine exam ( 44 Questions)
A nurse is reviewing the medical record of a client who has hyperthyroidism (Graves' disease). Which of the following serum laboratory findings should the nurse expect to be below the expected reference range?
Glucose levels are not directly affected by hyperthyroidism and are typically within the normal range unless the client has diabetes or another condition.
Triiodothyronine (T3) levels are elevated in hyperthyroidism due to excessive thyroid hormone production.
Thyroxine (T4) levels are also elevated in hyperthyroidism.
Thyroid stimulating hormone (TSH) is suppressed in hyperthyroidism because the thyroid gland produces excessive hormones, causing a negative feedback loop that reduces TSH levels.
Rationale:
A. Glucose levels are not directly affected by hyperthyroidism and are typically within the normal range unless the client has diabetes or another condition.
B. Triiodothyronine (T3) levels are elevated in hyperthyroidism due to excessive thyroid hormone production.
C. Thyroxine (T4) levels are also elevated in hyperthyroidism.
D. Thyroid stimulating hormone (TSH) is suppressed in hyperthyroidism because the thyroid gland produces excessive hormones, causing a negative feedback loop that reduces TSH levels.
