A patient is admitted for treatment of Cushing's syndrome. The nurse correlates this disease process to which alteration in endocrine function?
Decreased cortisol level.
Elevated glucocorticoid level.
Decreased aldosterone secretion.
Elevated insulin secretion.
The Correct Answer is B
Cushing's syndrome is a disorder characterized by excessive production or prolonged exposure to high levels of glucocorticoids, particularly cortisol. This can occur due to various reasons, such as the use of corticosteroid medications or overproduction of cortisol by the adrenal glands. Elevated glucocorticoid levels result in a variety of clinical manifestations associated with Cushing's syndrome, including weight gain, central obesity, muscle wasting, thinning of the skin, easy bruising, and impaired glucose metabolism.
It's important to note that Cushing's syndrome can have different underlying causes, such as adrenal tumors, pituitary tumors, or ectopic ACTH production. Regardless of the cause, the common feature in Cushing's syndrome is the excessive glucocorticoid levels, which contribute to the signs and symptoms of the condition.

Correct Answer is C
Explanation
Nitroprusside is a potent vasodilator medication used to rapidly reduce blood pressure in hypertensive emergencies. Its primary action is to dilate blood vessels, leading to a decrease in systemic vascular resistance and subsequent reduction in blood pressure.
Monitoring the client's blood pressure is crucial during the administration of nitroprusside to ensure that the medication is achieving the desired effect and that blood pressure is being appropriately controlled. The nurse will assess blood pressure frequently to adjust the infusion rate and titrate the medication to achieve the desired therapeutic effect while avoiding hypotension or other adverse effects.
Correct Answer is A
Explanation
The lower esophageal sphincter (LES) is a muscular ring located between the esophagus and stomach. Its function is to prevent the backflow of stomach acid and contents into the esophagus. In GERD, the LES becomes weak or relaxed, allowing stomach acid to flow back up into the esophagus, leading to symptoms such as heartburn, regurgitation, and chest pain.
