A nurse is assessing a client who is admitted for elective surgery and has a history of Addison's disease. Which of the following findings should the nurse expect? A. Hyperpigmentation B. Intention tremors C. Hirsutism D. Purple Striations

A (Addison's disease is an endocrine disorder that occurs when the adrenal glands do not produce enough of the hormone cortisol, and in some cases, the hormone aldosterone. The disease is characterized by weight loss, muscle weakness, fatigue, low blood pressure, and hyperpigmentation (darkening) of the skin in both exposed and non-exposed parts of the body.)

A client is admitted to the hospital with Cushing Syndrome. On the physical assessment of the client, what should the nurse expect to find? A. Hypertension, peripheral edema, and petechiae B. Weight loss, buffalo hump and, moon face with acne C. Abdominal and buttocks striae, truncal obesity, and hypotension D. Anorexia, signs of dehydration, and hyperpigmentation of the skin

A (The effects of Adenocorticotropic hormone (ACTH) excess, especially the glucorticoids-- leads to weight gain from accumulation and redistribution of adipose tissue.)

A nurse is caring for a child who has Addison's disease. Which of the following actions should the nurse take? A. Teach the parents about cortisol replacement therapy. B. Place the child on a low-sodium diet C. Monitor the child for fluid-volume excess D. Discuss the manifestations of hypoglycemia with the parents.

A (The nurse should plan to teach the child's parents about cortisol replacement therapy. Administration of glucocorticoids and mineralocorticoids is necessary because inadequate supplies or a sudden cessation of the medications can cause acute adrenal crisis.)

A nurse is caring for a client who has Cushing's disease. The nurse should identify that clients who are at risk for which of the following? A. Infection B. Gastric ulcer C. Renal calculi D. Bone fractures

A, B, D (Suppression of the immune system places the client at risk for infection. Clients are at higher risk for bone fractures due to decrease calcium absorption which leads to osteoporosis. These clients are a risk for gastric ulcers due to the overproduction of cortisol inhibits the production of the protective lining in the stomach. Clients with Cushing's do not have a risk for the development of renal calculi.)

A nurse is assessing a client who has Cushing's syndrome. Which of the following interventions should the nurse expect to perform? (Select all that apply.) A. Assess blood glucose level B. Assess for neck vein distension C. Monitor for an irregular heart rate D. Monitor for postural hypotension E. Weight the client daily

A, B, E

A nurse is assessing a client who has Cushing's syndrome. Which of the following findings should the nurse expect? (Select all that apply): A. Alopecia B. Tremors C. Moon face D. Purple striations E. Buffalo hump

A, C, D, E (MY ANSWER Alopecia is correct. Clients who have Cushing's syndrome can develop hirsutism, which is excessive body hair. Women can also develop alopecia, in the form of male pattern baldness.Tremors is incorrect. Tremors are not a common manifestation of Cushing's syndrome.Moon face is correct. Moon face, which is manifested by a round, red, full face, is a common manifestation of Cushing's syndrome.Purple striations is correct. Purple striations on the skin of the abdomen, thighs, and breasts are common manifestations of Cushing's syndrome.Buffalo hump is correct. Buffalo hump, which is a collection of fat between the shoulder blades, is a common manifestation of Cushing's syndrome.)

Most common cause of endogenous Cushing syndrome.

ACTH-secreting pituitary adenoma

Increases reabsorption of water by the tubules of the kidney

ADH

Secretes GH, prolactin, and other tropic hormones

Anterior pituitary

A nurse is assessing four clients on a medical unit. The nurse should identify which of the following clients as exhibiting positive manifestations of hypercortisolism? A. A client who has a butterfly rash on his face B. Moon face C. A client who has a positive Chvostek's sign D. A client who has muscle hypertrophy

B (A client who has a moon face and fat pads on his neck, back and shoulders is exhibiting manifestations of hypercortisolism or Cushing's syndrome.)

A staff nurse is teaching a client who has Addison's disease about the disease process. The client asks the nurse what causes Addison's disease. Which of the following responses should the nurse make? A. "It is caused by the lack of production of insulin by the pancreas." B. "It is caused by the lack of production of aldosterone by the adrenal gland." C. "It is caused by the overproduction of growth hormone by the pituitary gland." D. "It is caused by the overproduction of PTH by the parathyroid gland."

B (Addison's disease is caused by a lack of production of the adrenocorticotropic hormones (cortisol and aldosterone) by the adrenal gland.)

A nurse is teaching a client who has been taking prednisone to treat asthma and has a new prescription to discontinue the medication. The nurse should explain to the client to reduce the dose gradually to prevent which of the following adverse effects? A. Hyperglycemia B. Adrenocortical insufficiency C. Severe dehydration D. Rebound pulmonary congestion

B (Prednisone, a corticosteroid, is similar to cortisol, the glucocorticoid hormone produced by the adrenal glands. It relieves inflammation and is used to treat certain forms of arthritis, severe allergies, autoimmune disorders, and asthma. Administration of glucocorticoids can suppress production of glucocorticoids, and an abrupt withdrawal of the drug can lead to a syndrome of adrenal insufficiency.)

Which outcome is a priority for the client with Addison's disease? A. Adherence to a 2-gm sodium diet B. Maintenance of medication compliance C. Prevention of hypertensive episodes.

B (The maintenance of medical compliance is critical. Clients should never stop taking the prescribed medication without taking to their healthcare provider.)

A nurse is providing dietary teaching for a client who has Cushing's disease. Which of the following recommendations should the nurse include in the teaching? A. Limit intake of potassium-rich foods B. Restrict sodium intake C. Increase carbohydrate intake D. Decrease protein intake

B (The nurse should recommend the client to restrict sodium intake to control fluid volume. This restriction can range from "no-added-salt" to table foods to a restriction of 2 g/day.)

A nurse is assessing a client who has Addison's disease and is at risk for Addisonian crisis. Which of the following actions should the nurse take? A. Provide a low-carbohydrate diet B. Weigh the client daily C. Administer oral corticosteroids D. Restrict fluid intake

B (Weigh the client daily. Addison's disease is an endocrine disorder that causes weight loss, muscle weakness, fatigue, low blood pressure, and hyperpigmentation (darkening) of the skin. Obtaining the client's daily weight will alert the nurse that dehydration is developing, which could indicate an impending crisis.)

The client with Cushing's disease needs to modify dietary intake to control symptoms. In addition to increasing protein. Which strategy would be most appropriate? A. Increase calories B. Restrict sodium C. Restrict potassium D. Reduce fat to 10%

B (restricting sodium thereby reduces fluid retention)
