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: Fatigue is a common symptom of ITP but is not the primary concern for monitoring, as it does not directly indicate the severity of the condition.
Choice B reason: While monitoring for side effects of immunosuppressants is important, it is not the priority concern. The primary issue in ITP is the low platelet count, which poses a risk of bleeding.
Choice C reason: Thrombocytopenia, or low platelet count, is the hallmark of ITP and the main concern for monitoring, as it increases the risk of bleeding and bruising.
Choice D reason: Infection is a risk due to the potential use of immunosuppressants in treatment; however, the immediate concern in ITP management is the platelet count and associated bleeding risk.
Correct Answer is C
Explanation
Choice A reason: Renal function is not typically reestablished during the oliguric phase of acute kidney injury; this phase is characterized by a significant reduction in urine output due to renal tubule damage.
Choice B reason: BUN and creatinine levels usually increase during the oliguric phase because the kidneys' ability to filter and excrete these waste products is compromised.
Choice C reason: The oliguric phase is defined by a urine output of less than 400 mL per 24 hours, which is a result of decreased kidney function and damage to the renal tubules.
Choice D reason: The GFR does not recover during the oliguric phase; instead, it is typically low due to reduced kidney function. Recovery of GFR occurs later in the recovery phase of acute kidney injury.
