. 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."
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. Ketoacidosis: DKA presents with symptoms like polyuria, polydipsia, dehydration, and fruity breath, not lightheadedness and sweating.
B. Hypoglycemia. Symptoms like sweating, tachycardia, lightheadedness, and shakiness indicate hypoglycemia, a common complication in type 1 diabetes.
C. Nephropathy: Nephropathy is a chronic complication of diabetes and does not present with these acute symptoms.
D. Hyperglycemia: Hyperglycemia causes symptoms like thirst, frequent urination, and fatigue but does not typically cause sweating or shakiness.
Correct Answer is B
Explanation
A. Check the client for hypoglycemia 4 hr after the insulin lispro injection: Insulin lispro is rapid-acting, with a peak effect 1-2 hours after administration. Monitoring for hypoglycemia should focus on this timeframe, not 4 hours later.
B. Inject insulin lispro 15 min before a meal: Insulin lispro has an onset of action of about 15 minutes, making it ideal to administer shortly before meals to match glucose absorption and prevent postprandial hyperglycemia.
C. Administer insulin lispro in the same syringe as a short-acting insulin: Mixing insulin lispro with other insulins is not recommended; each type has specific mixing guidelines, and lispro is typically given alone.
D. Monitor the client for polyuria after the insulin lispro injection: Polyuria is a symptom of hyperglycemia, not an expected finding after insulin administration. Insulin lispro should reduce hyperglycemia and associated symptoms.
