A patient who is disoriented and reports a headache and muscle cramps is hospitalized with syndrome of inappropriate antidiuretic hormone (SIADH). Which initial laboratory result would the nurse expect?

Choice A reason: Observing for signs of hypotension is not typically a primary concern for patients with Cushing syndrome. These patients are more likely to experience hypertension due to increased cortisol levels, which cause sodium and water retention, rather than hypotension. Therefore, while monitoring blood pressure is important, focusing specifically on hypotension is not relevant to the typical presentation of Cushing syndrome.
Choice B reason: Monitoring blood glucose levels is a crucial intervention for patients with Cushing syndrome. Increased cortisol levels lead to hyperglycemia and glucose intolerance. Patients may develop diabetes mellitus as a result of chronic hypercortisolism. Regular monitoring of blood glucose levels helps in managing and controlling hyperglycemia and adjusting medication as necessary to maintain stable glucose levels.
Choice C reason: Protecting the patient from exposure to infection is essential in caring for patients with Cushing syndrome. Elevated cortisol levels suppress the immune system, making patients more susceptible to infections. Implementing infection control measures, such as hand hygiene, using personal protective equipment, and monitoring for signs of infection, are vital to prevent complications and ensure patient safety.
Choice D reason: Restricting protein intake is not a recommended intervention for patients with Cushing syndrome. In fact, these patients often require a diet high in protein to counteract the muscle wasting and weakness caused by excessive cortisol levels. Adequate protein intake helps in maintaining muscle mass and overall health, making restriction counterproductive.

Choice A reason: Monitoring potassium levels is essential for various medical conditions, but it is not specifically used to evaluate the effects of therapy for acute pancreatitis. Potassium levels may be monitored to assess overall electrolyte balance and kidney function, but they do not provide direct information about pancreatic inflammation or damage.
Choice B reason: Monitoring lipase levels is crucial in evaluating the effects of therapy for a patient with acute pancreatitis. Lipase is an enzyme produced by the pancreas, and its levels rise significantly during an acute episode of pancreatitis. Elevated lipase levels are a sensitive and specific indicator of pancreatic inflammation and damage. By regularly measuring lipase levels, healthcare providers can assess the severity of the condition, monitor the patient's response to treatment, and make necessary adjustments to the therapeutic regimen.
Choice C reason: Calcium levels are not typically used to evaluate the effects of therapy for acute pancreatitis. Although hypercalcemia (high calcium levels) can be a risk factor for developing pancreatitis, monitoring calcium levels is not a standard method for assessing the effectiveness of treatment for the condition.
Choice D reason: Bilirubin levels are not directly related to the evaluation of therapy for acute pancreatitis. Bilirubin is a breakdown product of hemoglobin and is primarily used to assess liver function and diagnose conditions such as jaundice or liver disease. While liver function tests may be performed in patients with pancreatitis to rule out concurrent liver issues, bilirubin levels alone do not provide information about the effectiveness of therapy for pancreatitis.
