A nurse is talking with a client whose thyroid stimulating hormone (TSH) level will be measured. Which of the following statements by the nurse explains the purpose of this test?
The test measures the hormone that attaches to a protein in your blood.
The test measures the hormone that feeds the thyroid gland.
The test measures the hormone that indicates the metabolic rate.
The test measures the hormone that controls energy levels.
The Correct Answer is C
Choice A reason: The statement is incorrect because TSH does not attach to a protein in the blood; it stimulates the thyroid gland to produce thyroid hormones.
Choice B reason: This choice is partially correct. TSH does stimulate the thyroid gland, but the main purpose of the test is not to measure the 'feeding' of the gland but to assess its function and how well it's producing thyroid hormones.
Choice C reason: This is the correct statement. TSH levels are measured to determine the thyroid gland's activity, which directly influences the metabolic rate. The normal range for TSH levels in adults is typically 0.4 to 4.0 milliunits per liter (mU/L). However, these values can vary slightly based on the laboratory and the age of the individual.
Choice D reason: While TSH does influence energy levels by regulating thyroid hormone production, this choice does not directly explain the purpose of measuring TSH levels.

Correct Answer is D
Explanation
Choice A reason: The prone position is not suitable for abdominal paracentesis as it does not allow access to the abdominal cavity.
Choice B reason: The lateral position is also not suitable as it can cause the fluid to shift, making it difficult to remove.
Choice C reason: While the supine position is commonly used for many medical procedures, it is not the best choice for abdominal paracentesis due to the distribution of fluid.
Choice D reason: The upright position is preferred because it allows the fluid to pool at the lowest point of the abdominal cavity, facilitating its removal.
Correct Answer is ["A","B","D"]
Explanation
Choice A reason: Enlarged distal extremities are a classic sign of acromegaly due to the overproduction of growth hormone, which affects the growth plates in the bones.
Choice B reason: Coarse facial features, including a protruding jaw and brow, enlarged nose, and thickened lips, are common in acromegaly due to the excessive growth of facial bones and soft tissues.
Choice C reason: Loss of color discrimination is not typically associated with acromegaly. This symptom may be related to other conditions affecting the optic nerve or the brain.
Choice D reason: Hepatomegaly, or an enlarged liver, can occur in acromegaly as a result of increased growth factor effects on the liver.
Choice E reason: Moon face is associated with conditions that lead to corticosteroid excess, such as Cushing's syndrome, but can also appear in acromegaly due to soft tissue swelling.
