A nurse is in a provider's office is reviewing the health record of a client who is being evaluated for Grave's disease. Which of the following is an expected laboratory finding for this client?
Decreased free thyroxine index
Decreased thyroid stimulating hormone
Decreased triiodothyronine
Decreased thyrotropin receptor antibodies
The Correct Answer is B
A. Decreased free thyroxine index: In Graves' disease, there is an overproduction of thyroid hormones, including thyroxine (T4), leading to an increase in the free thyroxine index, not a decrease. Elevated T4 levels are typical in hyperthyroidism associated with Graves' disease.
B. Decreased thyroid stimulating hormone (TSH): In Graves' disease, the body produces excess thyroid hormones, which suppresses the pituitary gland’s production of TSH. As a result, TSH levels are typically low in Graves' disease.
C. Decreased triiodothyronine (T3): Graves' disease usually results in increased levels of T3 and T4 due to the overactive thyroid. A decrease in T3 would be inconsistent with the hyperthyroid state seen in this disorder.
D. Decreased thyrotropin receptor antibodies: In Graves' disease, there is an increase in thyrotropin receptor antibodies, which stimulate the thyroid to produce excess thyroid hormones. These antibodies are often elevated, not decreased.

Correct Answer is A
Explanation
A. Glycosylated hemoglobin (HbA1C): The HbA1C test provides an average measure of blood glucose levels over the past 8 to 12 weeks. It reflects the percentage of hemoglobin that has glucose attached to it, giving an indication of long-term blood sugar control.
B. Oral glucose tolerance test: This test measures the body’s response to glucose by checking blood sugar levels after drinking a sugary solution. It does not provide an average of blood glucose over weeks, but rather, it assesses blood glucose levels at specific time points after glucose ingestion.
C. Postprandial glucose test: This test measures blood glucose levels after eating a meal, typically 1 to 2 hours later. It provides information about immediate glucose levels, not long-term glucose control over weeks.
D. Fasting blood sugar (FSBS): This test measures blood glucose levels after fasting for at least 8 hours. It gives a snapshot of current glucose levels but does not provide a measure of glucose control over weeks.
Correct Answer is A
Explanation
A. Clients with type 1 or type 2 diabetes mellitus experiencing illness, stress, or surgery: Sliding scale insulin is often used during illness, stress, or surgery to adjust insulin doses based on blood glucose levels in both type 1 and type 2 diabetes.
B. Clients participating in a rigorous sport or activity: Sliding scale insulin is not typically used during exercise. Insulin adjustments for exercise are generally based on the individual’s patterns and current glucose levels.
C. Clients with type 1 diabetes mellitus experiencing illness, stress, or surgery: While Type 1 diabetics require sliding scale insulin in these situations, this option excludes Type 2 diabetics who also frequently need sliding scale insulin during periods of acute illness or stress.
D. Clients newly diagnosed with type 2 diabetes mellitus: Newly diagnosed type 2 diabetes clients typically begin with oral medications or long-acting insulin, not sliding scale insulin, which is used during acute conditions.
