. A nurse is reinforcing teaching with a client who is scheduled for a blood test to measure her thyroid-stimulating hormone (TSH) level. Which of the following statements should the nurse give?

A.

"This test measures the absorption of iodine and how it relates to the thyroid gland."

B.

"The test determines whether your thyroid gland is overactive, appropriately active, or underactive."

C.

"This test detects antithyroid antibodies in your blood."

D.

"This test measures the amount of thyroid hormone that attaches to a protein in your blood."

Answer and Explanation

The Correct Answer is B

A. "This test measures the absorption of iodine and how it relates to the thyroid gland.": This describes a radioactive iodine uptake (RAIU) test, not TSH testing.

B. "The test determines whether your thyroid gland is overactive, appropriately active, or underactive.": A TSH test evaluates thyroid function by measuring the pituitary gland’s response to circulating thyroid hormone levels.

C. "This test detects antithyroid antibodies in your blood.": This describes a thyroid antibody test, which is used to diagnose autoimmune thyroid conditions like Hashimoto’s thyroiditis or Graves’ disease.

D. "This test measures the amount of thyroid hormone that attaches to a protein in your blood.": This describes a thyroid hormone-binding ratio test, not TSH.

Correct Answer is A

Explanation

A. Increased urine output: Diabetes insipidus (DI) results from insufficient antidiuretic hormone (ADH) or kidney insensitivity to ADH, leading to polyuria and dehydration.

B. Fluid retention: Fluid retention is more indicative of the syndrome of inappropriate antidiuretic hormone (SIADH), not DI.

C. Hypertension: DI typically causes dehydration and low blood pressure, not hypertension.

D. Elevated blood glucose: Elevated glucose is a feature of diabetes mellitus, not DI, which is unrelated to glucose metabolism.

Correct Answer is C

Explanation

A. 0730: At this time, the client is eating breakfast, which aligns with the onset of NPH insulin but does not address its peak effect.

B. 1230: This coincides with lunch, which matches the duration of NPH insulin but not the time when hypoglycemia is most likely to occur.

C. 1500: NPH insulin peaks about 4–12 hours after administration. Providing a snack at 1500 helps prevent hypoglycemia during the peak insulin activity.

D. 0900: This time is too early to account for the peak effect of NPH insulin, which usually occurs later in the day.
