A 40-year-old female client has a family history of thyroid problems and is being seen by the primary health care provider for unintentional weight loss, irritability, and chest discomfort. Her probable diagnosis is hyperthyroidism, which the primary health care provider plans to confirm by laboratory testing. What additional physical assessment findings would the nurse expect to be present in this client? Select all that apply.

Choice A reason: Checking the blood pressure and pulse is important as part of the routine monitoring of vital signs to assess the patient's hemodynamic status. However, it is not the first action to take following a thyroidectomy. Ensuring that the patient's airway is clear and that there is no respiratory distress is paramount, as any compromise in the airway can lead to life-threatening situations. Blood pressure and pulse can be checked after confirming the patient is breathing properly.
Choice B reason: Observing the dressing for bleeding is also important because post-operative bleeding can be a serious concern. However, this action should follow the assessment of the patient's airway. If the patient is experiencing respiratory distress, addressing the airway takes precedence. Once it is confirmed that the airway is clear, then the nurse can check for bleeding and ensure the dressing is intact.
Choice C reason: Supporting the patient's head with pillows is beneficial for comfort and proper positioning, especially to avoid strain on the surgical site. However, positioning should not be the first priority. Ensuring that the patient's airway is clear and that there is no respiratory compromise is the most urgent concern. Proper positioning can be done after confirming that the patient is breathing adequately.
Choice D reason: Assessing the patient's respiratory effort is the first and most critical action. Following a thyroidectomy, there is a risk of respiratory complications due to potential swelling, bleeding, or damage to the trachea and surrounding structures. Immediate assessment of respiratory effort ensures that the airway is patent and the patient is not in respiratory distress. This step is crucial to prevent hypoxia and other serious complications.

Choice A reason: Increased serum chloride is not a typical finding associated with syndrome of inappropriate antidiuretic hormone (SIADH). In SIADH, the body's regulation of water is impaired, leading to water retention and dilutional hyponatremia. Serum chloride levels might not be significantly affected and are not the primary laboratory indicator for this condition.
Choice B reason: Elevated hematocrit is not directly related to SIADH. Hematocrit levels reflect the proportion of red blood cells in the blood. In SIADH, the main issue is water retention leading to dilutional hyponatremia, rather than changes in red blood cell concentration. Therefore, hematocrit levels are not a key laboratory finding in this disorder.
Choice C reason: Decreased serum sodium, or hyponatremia, is a hallmark finding in SIADH. The excessive release of antidiuretic hormone (ADH) leads to water retention, diluting the sodium in the blood and resulting in low serum sodium levels. This hyponatremia can cause symptoms such as disorientation, headache, and muscle cramps, as seen in the patient. Monitoring and correcting serum sodium levels is crucial in the management of SIADH.
Choice D reason: Low urine specific gravity is not expected in SIADH. In fact, patients with SIADH typically have a high urine specific gravity due to the excessive release of ADH, which causes the kidneys to reabsorb water and concentrate the urine. This concentrated urine reflects the body's attempt to reduce water excretion in response to elevated ADH levels. Therefore, low urine specific gravity would not be an initial laboratory finding in this condition.
