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 C
Explanation
Choice A reason: Keeping the client NPO (nothing by mouth) is not directly related to preventing a thyroid crisis. While it may be necessary in some situations, such as preoperative care, it does not address the hyperthyroid state.
Choice B reason: Observing the client for signs of hypocalcemia is important, especially after thyroid surgery, as hypocalcemia can occur due to accidental removal or damage to the parathyroid glands. However, it is not a preventive measure for a thyroid crisis.
Choice C reason: Providing a quiet, low stimulus environment can help reduce stress and agitation, which are potential triggers for a thyroid crisis. Stress can exacerbate hyperthyroid symptoms and precipitate a crisis.
Choice D reason: Aspirin is contraindicated in clients with hyperthyroidism as it can increase thyroid hormone levels by displacing them from their binding proteins. This can potentially worsen the condition and lead to a crisis.
Correct Answer is D
Explanation
Choice A reason: This choice is incorrect. A stroke involving the right cerebral hemisphere typically affects the left side of the body and can cause problems with spatial and perceptual abilities, not necessarily with language or discrimination of words and letters, which are more commonly associated with left hemisphere strokes⁸.
Choice B reason: Motor retardation is not specific to right hemisphere strokes. While right hemisphere strokes can cause weakness on the left side of the body, the term 'motor retardation' is not commonly used to describe this symptom⁸.
Choice C reason: This choice is incorrect because deficits in the right visual field would suggest a problem with the left cerebral hemisphere, not the right. A right hemisphere stroke typically causes problems with the left visual field⁸.
Choice D reason: This is the correct choice. Individuals with right hemisphere strokes may exhibit poor impulse control, as the right hemisphere is involved in judgment and behavior regulation⁸.
