A nurse is assessing a client who has Graves’ disease. The nurse should expect which of the following laboratory results?
Decreased thyroxine (T4) level.
Decreased triiodothyronine (T3) level.
Decreased thyroid-stimulating immunoglobulins (TSI) percentage.
Decreased thyroid-stimulating hormone (TSH) level.
The Correct Answer is D
Choice A Reason:
A decreased thyroxine (T4) level is not expected in a client with Graves’ disease. Graves’ disease is an autoimmune disorder that leads to hyperthyroidism, where the thyroid gland produces excessive amounts of thyroid hormones, including T4. Therefore, the T4 level is typically elevated, not decreased.
Choice B Reason:
Similarly, a decreased triiodothyronine (T3) level is not expected in Graves’ disease. Like T4, T3 levels are usually elevated due to the overactive thyroid gland. T3 is the active form of thyroid hormone and is often increased in hyperthyroid conditions.
Choice C Reason:
Decreased thyroid-stimulating immunoglobulins (TSI) percentage is incorrect. In Graves’ disease, TSI levels are elevated because these antibodies stimulate the thyroid gland to produce more thyroid hormones. TSI mimics the action of TSH, leading to increased production of T3 and T4.
Choice D Reason:
Decreased thyroid-stimulating hormone (TSH) level is the correct answer. In Graves’ disease, the excessive thyroid hormones (T3 and T4) exert negative feedback on the pituitary gland, leading to suppressed TSH production. Therefore, TSH levels are typically low in patients with Graves’ disease.

Correct Answer is ["B","C","D"]
Explanation
Choice A Reason:
Administering 0.45% NS (normal saline) at 50 mL/hr is not appropriate for a client with SIADH. This hypotonic solution can exacerbate the condition by increasing the water retention and further diluting the serum sodium levels, worsening hyponatremia. Instead, fluid restriction and hypertonic saline (such as 3% saline) are typically used to manage SIADH.
Choice B Reason:
Obtaining daily weight is crucial in managing SIADH. Daily weights help monitor fluid retention and detect any sudden changes in body weight, which can indicate worsening fluid overload or effective treatment. Accurate weight measurements are essential for assessing the client’s fluid balance and guiding treatment decisions.
Choice C Reason:
Maintaining seizure precautions is necessary for clients with SIADH because severe hyponatremia can lead to neurological symptoms, including seizures. Implementing seizure precautions helps ensure the client’s safety and allows for prompt intervention if a seizure occurs.
Choice D Reason:
Administering 3% saline as ordered is appropriate for treating severe hyponatremia in SIADH. Hypertonic saline helps increase serum sodium levels and reduce the risk of neurological complications. It must be administered carefully and under close monitoring to avoid rapid correction of sodium levels, which can lead to osmotic demyelination syndrome.
Choice E Reason:
Encouraging fluid intake is not appropriate for clients with SIADH. Fluid restriction is a key component of managing SIADH to prevent further dilution of serum sodium levels. Encouraging fluid intake would counteract this goal and worsen the client’s condition.
Correct Answer is B
Explanation
Choice A: You May Bring Some Music to Listen to for Distraction
Bringing music for distraction is generally not a standard instruction given before an EEG. While listening to music might help some patients relax, it is not a critical part of the preparation for the test. The primary focus of EEG preparation is to ensure accurate readings of brain activity, which can be influenced by various factors such as medication and sleep.
Choice B: Do Not Take Any Sedatives 12 to 24 Hours Before the Test
Avoiding sedatives before an EEG is crucial because these medications can alter brain activity and affect the test results. Sedatives can suppress the electrical activity in the brain, leading to inaccurate readings. Therefore, it is essential for patients to avoid taking any sedatives 12 to 24 hours before the test to ensure the EEG captures the brain’s natural activity.
Choice C: You Will Need to Have Someone to Drive You Home
This instruction is typically given if the patient is expected to be sedated or if the test involves procedures that might impair their ability to drive. However, for a standard EEG, patients are usually not sedated, and there is no need for someone to drive them home. This instruction is more relevant for other types of medical procedures that involve sedation.
Choice D: Please Do Not Have Anything to Eat or Drink After Midnight
Fasting is not a standard requirement for an EEG. Patients are generally allowed to eat and drink before the test. However, they are often advised to avoid caffeine as it can affect brain activity. The instruction to avoid food and drink after midnight is more commonly associated with procedures that require anesthesia or sedation, not an EEG.
