The nurse manager is creating the budget for the next fiscal year. Because the client census has been higher in the past year, more supplies were used. This cost was reflected as:
1. Fixed costs. 2. Variable costs. 3. Direct costs. 4. Indirect costs.

The patient, recently diagnosed with HIV, is waiting for results of his lab work to determine his T cell count and says to the nurse, "What exactly is a T cell?" What is the nurse's best response?
A) "T cells are monocytes, which are a type of white blood cell that helps to fight off infections and other foreign bodies that enter the body." B) "T cells are neutrophils, which are a type of white blood cell that helps to fight off infections and other foreign bodies that enter the body." C) "T cells are lymphocytes, which are a type of white blood cell that helps to fight off infections and other foreign bodies that enter the body." D) "T cells are basophils, which are a type of white blood cell that helps to fight off infections and other foreign bodies that enter the body."
Leda is a 38-year-old woman who began to experience weight gain, mood swings, and weakness. When her periods became irregular, she went to her physician
Leda's physician heard the symptoms Leda was concerned about and then ordered a 24-hour free cortisol urine test and an overnight dexamethasone suppression test and measured her serum ACTH levels. The results indicated that Leda had Cushing disease, a condition caused by the hypersecretion of ACTH by the anterior pituitary and resulting in elevated cortisol levels. To confirm the diagnosis, Leda's physician ordered a cranial MRI to identify the presence of a pituitary tumor. The dexamethasone test involves the administration of a synthetic glucocorticoid (i.e., cortisol). Knowing what you do about negative feedback mechanisms, how might this test be used to assess pituitary function? Describe how the steroid hormones, like cortisol, are metabolized in the body. What are the advantages of using a 24-hour urine test to measure this hormone? Protein-based and steroid-based hormones trigger cellular responses in different ways. What are the differences between the mechanism of action of ACTH and cortisol on target cells?
