. 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?

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

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

"This test detects antithyroid antibodies in your blood."

"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 B

Explanation

A. Has no peak: NPH insulin has a distinct peak time, unlike long-acting insulins such as glargine or detemir, which have no peak.

B. 4 to 14 hr: NPH insulin is an intermediate-acting insulin with an onset of 1-2 hours, a peak between 4-14 hours, and a duration of 16-24 hours.

C. 1 to 5 hr: This timeframe describes the peak of short-acting insulins such as regular insulin.

D. 30 min to 3 hr: This timeframe describes the peak of rapid-acting insulins such as lispro, aspart, or glulisine.

A. "I will discard the current vial of insulin after six doses have been withdrawn." B. "I will return any unused vials of insulin to the pharmacy once they have been on the unit for 1 month." C. "I can keep the current vial of insulin in use stored at room temperature." D. "I will store unopened vials of insulin in the freezer."

Correct Answer is C

Explanation

A. "I will discard the current vial of insulin after six doses have been withdrawn.": Insulin vials can be used for up to 28 days when stored at room temperature, not discarded based on the number of doses withdrawn.

B. "I will return any unused vials of insulin to the pharmacy once they have been on the unit for 1 month.": Unused insulin vials should be stored properly (refrigerated for unopened vials) and do not need to be returned unless there is an error or expired stock.

C. "I can keep the current vial of insulin in use stored at room temperature.": Once opened, insulin vials can be stored at room temperature (below 86°F or 30°C) for up to 28 days to prevent degradation.

D. "I will store unopened vials of insulin in the freezer.": Freezing insulin damages its effectiveness; unopened insulin should be refrigerated but never frozen.
