Adrenal Disorders (NCLEX)

The nurse is caring for a client in acute addisonian crisis. Which laboratory data would the nurse expect to find? 1. Hyperkalemia 2. Reduced blood urea nitrogen (BUN) 3. Hypernatremia 4. Hyperglycemia

1 In adrenal insufficiency, the client has hyperkalemia due to reduced aldosterone secretion. BUN increases as the glomerular filtration rate is reduced. Hyponatremia is caused by reduced aldosterone secretion. Reduced cortisol secretion leads to impaired glyconeogenesis and a reduction of glycogen in the liver and muscle, causing hypoglycemia.

Following a unilateral adrenalectomy, the nurse would assess for hyperkalemia as indicated by: 1. muscle weakness. 2. tremors. 3. diaphoresis. 4. constipation.

1 Muscle weakness, bradycardia, nausea, diarrhea, and paresthesia of the hands, feet, tongue, and face are findings associated with hyperkalemia, which is transient and occurs from transient hypoaldosteronism when the adenoma is removed. Tremors, diaphoresis, and constipation aren't seen in hyperkalemia.

Discharge teaching for a patient receiving glucocorticoids would include the use of which medication for pain management? A. Aspirin (Acetylsalicylic acid) B. Acetaminophen (Tylenol) C. Ibuprofen D. Naprosyn (Naproxen)

B

A patient has Cushing's syndrome. The nurse expects which drug to be used to inhibit the function of the adrenal cortex in the treatment of this syndrome? A. Fludrocortisone (Florinef) B. Dexamethasone (generic) C. Aminoglutethimide (Cytadren) D. Hydrocortisone (Solu-Cortef)

C

A patient is taking prednisolone and fludrocortisone (Florinef). When teaching this patient about dietary intake, the nurse will instruct the patient to consume a diet a. high in carbohydrates. b. high in fat. c. high in protein. d. low in potassium

C Patients receiving fludrocortisone are at risk for negative nitrogen balance and should consume a high-protein diet.

The nurse should monitor for increases in which laboratory value in a patient being treated with dexamethasone? a. Sodium b. Calcium c. Potassium d. Blood glucose

D Hyperglycemia, or increased blood glucose level, is an adverse effect of corticosteroid therapy. Sodium, calcium, and potassium levels are not affected directly by dexamethasone.

what is the primary treatment for this pheochromocytoma? a. adrenalectomy b. chemotherapy c. insulin therapy d. radiation

a. adrenalectomy

A nurse is caring for a client following an adrenalectomy and is monitoring for signs of adrenal insufficiency. Which of the following, if noted in the client, indicates signs and symptoms related to adrenal insufficiency? Select all that apply. 1. Double vision 2. Hypotension 3. Mental status changes 4. Weakness 5. Fever

2345 The nurse should be alert to signs and symptoms of adrenal insufficiency in a client following adrenalectomy. These signs and symptoms include weakness, hypotension, fever, and mental status changes. Double vision is generally not associated with this condition.

The client is scheduled for a bilateral adrenalectomy for Cushing's disease. Which information regarding the prescribed prednisone should the nurse teach? Select all that apply. 1. When discontinuing this medication, it must be tapered. 2. Take the medication regularly; do not skip doses. 3. Stop taking the medication if you develop a round face. 4. Notify the HCP if you start feeling thirsty all the time. 5. Wear a MedicAlert bracelet in case of an emergency.

245

The nurse is discussing the endocrine system with the client. Which endocrine gland secretes epinephrine and norepinephrine? 1. The pancreas. 2. The adrenal cortex. 3. The adrenal medulla. 4. The anterior pituitary gland

3

The client is three (3) days postoperative unilateral adrenalectomy. Which discharge instructions should the nurse teach? 1. Discuss the need for lifelong steroid replacement. 2. Instruct the client on administration of vasopressin. 3. Teach the client to care for the suprapubic Foley catheter. 4. Tell the client to notify the HCP if the incision is inflamed.

4

2. What cells are responsible for secreting catecholamines? A. Chromaffin B. Langerhans C. Enkephalin D. Parietal

A. Chromaffin

A nurse is reviewing discharge teaching with a client who has Cushing's syndrome. Which statement by the client indicates that the instructions related to dietary management were understood? 1. "I can eat foods that contain potassium." 2. "I will need to limit the amount of protein in my diet." 3. "I am fortunate that I can eat all the salty foods I enjoy." 4. "I am fortunate that I do not need to follow any special diet."

1 A diet that is low in calories, carbohydrates, and sodium but ample in protein and potassium content is encouraged for a client with Cushing's syndrome. Such a diet promotes weight loss, the reduction of edema and hypertension, the control of hypokalemia, and the rebuilding of wasted tissue.

A client is diagnosed with Cushing's syndrome. When reviewing the recent laboratory results, the nurse should expect an excess of which substance? 1. Calcium 2. Cortisol 3. Epinephrine 4. Norepinephrine

2 Cushing's syndrome is characterized by an excess of cortisol, a glucocorticoid. Glucocorticoids are produced by the adrenal cortex. Calcium would be decreased in this disorder. Epinephrine and norepinephrine are produced by the adrenal medulla.

A nurse is providing discharge instructions to a client who had a unilateral adrenalectomy. Which of the following will be a component of the instructions? 1. The reason for maintaining a diabetic diet 2. Instructions about early signs of a wound infection 3. Teaching regarding proper application of an ostomy pouch 4. The need for lifelong replacement of all adrenal hormones

2 A client who is undergoing a unilateral adrenalectomy will be placed on corticosteroids temporarily to avoid a cortisol deficiency. These medications will be gradually weaned in the postoperative period until they are discontinued. Because of the anti-inflammatory properties of corticosteroids, clients who undergo an adrenalectomy are at increased risk for developing wound infections. Because of this increased risk for infection, it is important for the client to know measures to prevent infection, early signs of infection, and what to do if an infection is present. Options 1, 3, and 4 are incorrect instructions.

a client admitted with pheochromocytoma returns from the operating room after adrenalectomy. which assessment is most concerning? a. glucose of 70 mg/dL b. potassium of 3.4mEq/L c. blood pressure of 169/98 mm Hg d. sodium of 146 mEq/L

c. blood pressure of 169/98 pheochromocytoma is a tumor in the adrenal medulla that produces catecholamines (epinephrine and norepinephrine). an excess of these catecholamines can cause severe HTN. surgery (adrenalectomy) alleviates the elevated blood pressure most of the time. electrolyte imbalances and blood sugar are not typically affected

A client with Addison's disease asks the nurse how a newly prescribed medication, fludrocortisone acetate (Florinef), will improve the condition. When formulating a response, the nurse should incorporate that a key action of this medication is to: 1. Help restore electrolyte balance. 2. Make the body produce more cortisol. 3. Replace insufficient circulating estrogens. 4. Alter the body's immune system functioning.

1 Fludrocortisone acetate is a long-acting oral medication with mineralocorticoid and moderate glucocorticoid activity. It is prescribed for the long-term management of Addison's disease. Mineralocorticoids cause renal reabsorption of sodium and chloride ions and the excretion of potassium and hydrogen ions. These actions help restore electrolyte balance in the body. The other options are incorrect.

The nurse is caring for a client with Addison's disease. The client asks the nurse about the risks associated with this disease, specifically about addisonian crisis. Regarding prevention of this complication, how should the nurse inform the client? 1. "You can take either hydrocortisone or fludrocortisone for replacement." 2. "You need to take your fludrocortisone 3 times a day to prevent a crisis." 3. "You need to increase salt in your diet, particularly during stressful situations." 4. "You need to decrease your dosages of glucocorticoids and mineralocorticoids during stressful situations."

4 Addison's disease is a result of adrenocortical insufficiency, and management is focused on treating the underlying cause. Hormone therapy is used for replacement. Hydrocortisone has both glucocorticoid and mineralocorticoid properties and needs to be taken 3 times daily, with two thirds of the daily dose taken on awakening. Fludrocortisone is taken once daily in the morning. Salt additives are necessary, particularly during times of stress, to compensate for excess heat or humidity as a result of the condition. There needs to be an increased dose of cortisol given for stressful situations such as surgery or hospitalization.

The nurse is caring for a client with a diagnosis of Addison's disease and is monitoring the client for signs of addisonian crisis. The nurse should assess the client for which manifestation that would be associated with this crisis? 1. Agitation 2. Diaphoresis 3. Restlessness 4. Severe abdominal pain

4 Addisonian crisis is a serious life-threatening response to acute adrenal insufficiency that most commonly is precipitated by a major stressor. The client in addisonian crisis may demonstrate any of the signs and symptoms of Addison's disease, but the primary problems are sudden profound weakness; severe abdominal, back, and leg pain; hyperpyrexia followed by hypothermia; peripheral vascular collapse; coma; and renal failure. The remaining options do not identify clinical manifestations associated with addisonian crisis.

A nurse teaches a client with Cushing's disease. Which dietary requirements should the nurse include in this client's teaching? (SATA) a. Low calcium b. Low carbohydrate c. Low protein d. Low calories e. Low sodium

BDE The client with Cushing's disease has weight gain, muscle loss, hyperglycemia, and sodium retention. Dietary modifications need to include reduction of carbohydrates and total calories to prevent or reduce the degree of hyperglycemia. Sodium retention causes water retention and hypertension. Clients are encouraged to restrict their sodium intake moderately. Clients often have bone density loss and need more calcium. Increased protein intake will help decrease muscle loss.

The client is admitted to rule out Cushing's syndrome. Which laboratory tests wouldthe nurse anticipate being ordered? 1. Plasma drug levels of quinidine, digoxin, and hydralazine. 2. Plasma levels of ACTH and cortisol. 3. 24-hour urine for metanephrine and catecholamine. 4. Spot urine for creatinine and white blood cells.

2 The adrenal gland secretes cortisol and the pituitary gland secretes adrenocorticotropic hormone (ACTH), a hormone used by the body to stimulate the production of cortisol.

The nurse is planning the care of a client diagnosed with Addison's disease. Which intervention should be included? 1. Administer steroid medications. 2. Place the client on fluid restriction. 3. Provide frequent stimulation. 4. Consult physical therapy for gait training.

The nurse is performing discharge teaching for a client diagnosed with Cushing'sdisease. Which statement made by the client demonstrates an understanding of theinstructions? 1. "I will be sure to notify my health-care provider if I start to run a fever." 2. "Before I stop taking the prednisone, I will be taught how to taper it off." 3. "If I get weak and shaky, I need to eat some hard candy or drink some juice." 4. "It is fine if I continue to participate in weekend games of tackle football."

1 Cushing's syndrome/disease predisposes the client to develop infections as a result of the immunosuppressive nature of the disease.

A client with a history of hypertension is diagnosed with primary hyperaldosteronism. This diagnosis indicates that the client's hypertension is caused by excessive hormone secretion from which gland? 1. Adrenal cortex 2. Pancreas 3. Adrenal medulla 4. Parathyroid

1 Excessive secretion of aldosterone in the adrenal cortex is responsible for the client's hypertension. This hormone acts on the renal tubule, where it promotes reabsorption of sodium and excretion of potassium and hydrogen ions. The pancreas mainly secretes hormones involved in fuel metabolism. The adrenal medulla secretes the catecholamines — epinephrine and norepinephrine. The parathyroids secrete parathyroid hormone.

The client diagnosed with Addison's disease is admitted to the emergency departmentafter a day at the lake. The client is lethargic, forgetful, and weak. Which interventionshould be the emergency department nurse's first action? 1. Start an IV with an 18-gauge needle and infuse NS rapidly. 2. Have the client wait in the waiting room until a bed is available. 3. Perform a complete head-to-toe assessment. 4. Collect urinalysis and blood samples for a CBC and calcium level.

1 This client has been exposed to wind and sun at the lake during the hours prior to being admitted to the emergency department. This predisposes the client to dehydration and an Addisonian crisis. Rapid IV fluid replacement is necessary.

Over secretion of the adrenocortical hormones leads to: A. Cushing's syndrome B. Addison's disease

A

The nurse is administering aminoglutethimide to a patient and will monitor for which adverse effects? (Select all that apply) A. Constipation B. Dizziness C. Anorexia D. Hypotension E. Lethargy

BCE

which is the most common symptom related to pheochromocytoma? a. pyuresis b. nausea and vomiting c. anxiety d. hypertension

d. hypertension

The nurse is performing discharge teaching for a client diagnosed with Cushing's disease. Which statement by the client demonstrates an understanding of the instructions? 1. "I will be sure to notify my health-care provider if I start to run a fever." 2. "Before I stop taking the prednisone, I will be taught how to taper it off." 3. "If I get weak and shaky, I need to eat some hard candy or drink some juice." 4. "It is fine if I continue to participate in weekend games of tackle football."

Which nursing diagnosis is most appropriate for a client with Addison's disease? 1. Risk for infection 2. Excessive fluid volume 3. Urinary retention 4. Hypothermia

1 Addison's disease decreases the production of all adrenal hormones, compromising the body's normal stress response and increasing the risk of infection. Other appropriate nursing diagnoses for a client with Addison's disease include Deficient fluid volume and Hyperthermia. Urinary retention isn't appropriate because Addison's disease causes polyuria.

The nurse is planning the care of a client diagnosed with Addison's disease. Whichinterventions should be included? 1. Administer steroid medications. 2. Place the client on fluid restriction. 3. Provide frequent stimulation. 4. Consult physical therapy for gait training.

1 Clients diagnosed with Addison's disease have adrenal gland hypofunction. The hormones normally produced by the gland must be replaced. Steroids and androgens are produced by the adrenal gland

Before discharge, what should a client with Addison's disease be instructed to do when exposed to periods of stress? 1. Administer hydrocortisone I.M. 2. Drink 8 oz of fluids. 3. Perform capillary blood glucose monitoring four times daily. 4. Continue to take his usual dose of hydrocortisone.

1 Clients with Addison's disease and their family members should know how to administer I.M. hydrocortisone during periods of stress. It's important to keep well hydrated during stress, but the critical component in this situation is to know how and when to use I.M. hydrocortisone. Capillary blood glucose monitoring isn't indicated in this situation because the client doesn't have diabetes mellitus. Hydrocortisone replacement doesn't cause insulin resistance.

When assessing a client with pheochromocytoma, a tumor of the adrenal medulla that secretes excessive catecholamine, the nurse is most likely to detect: 1. a blood pressure of 130/70 mm Hg. 2. a blood glucose level of 130 mg/dl. 3. bradycardia. 4. a blood pressure of 176/88 mm Hg.

4 Pheochromocytoma, a tumor of the adrenal medulla that secretes excessive catecholamine, causes hypertension, tachycardia, hyperglycemia, hypermetabolism, and weight loss. It isn't associated with the other options.

A nurse notes in the medical record that a client with Cushing's syndrome is experiencing fluid overload. Which interventions should be included in the plan of care? Select all that apply. 1. Monitoring daily weight 2. Monitoring intake and output 3. Maintaining a low-potassium diet 4. Monitoring extremities for edema 5. Maintaining a low-sodium diet

1245 The client with Cushing's syndrome experiencing fluid overload should be maintained on a high-potassium and low-sodium diet. Decreased sodium intake decreases renal retention of sodium and water. Monitoring weight, intake, output, and extremities for edema are all appropriate interventions for such a nursing diagnosis.

The nurse is assessing a client in an outpatient clinic. Which assessment data are a risk factor for developing pheochromocytoma? 1. A history of skin cancer. 2. A history of high blood pressure. 3. A family history of adrenal tumors. 4. A family history of migraine headaches.

3

The nurse writes a problem of "altered body image" for a 34-year-old client diagnosed with Cushing's disease. Which intervention should be implemented? 1. Monitor blood glucose levels prior to meals and at bedtime. 2. Perform a head-to-toe assessment on the client every shift. 3. Use therapeutic communication to allow the client to discuss feelings. 4. Assess bowel sounds and temperature every four (4) hours.

3

The client diagnosed with Cushing's disease has undergone a unilateral adrenalectomy. Which discharge instructions should the nurse teach? 1. Instruct the client to take the glucocorticosteroid and mineralcorticosteroid medications as prescribed. 2. Teach the client regarding sexual functioning and androgen replacement therapy. 3. Explain the signs and symptoms of infection and when to call the health-care provider. 4. Demonstrate turn, cough, and deep-breathing exercises that the client should perform every (2) hours.

3 This is information given to all surgical clients on discharge.

The nurse is admitting a client to rule out aldosteronism. Which assessment data support the client's diagnosis? 1. Temperature. 2. Pulse. 3. Respirations. 4. Blood pressure.

4

The nurse is developing a plan of care for the client diagnosed with acquired immunodeficiency syndrome (AIDS) who has developed an infection in the adrenal gland.Which problem would have the highest priority? 1. Altered body image. 2. Activity intolerance. 3. Impaired coping. 4. Fluid volume deficit.

4 Fluid volume deficit (dehydration) can leadto circulatory impairment and hyperkalemia.

The nursing care for the client in addisonian crisis should include which intervention? 1. Encouraging independence with activities of daily living (ADLs) 2. Allowing ambulation as tolerated 3. Offering extra blankets and raising the heat in the room to keep the client warm 4. Placing the client in a private room

4 The client in addisonian crisis has a reduced ability to cope with stress due to an inability to produce corticosteroids. Compared to a multibed room, a private room is easier to keep quiet, dimly lit, and temperature controlled. Also, visitors can be limited to reduce noise, promote rest, and decrease the risk of infection. The client should be kept on bed rest, receiving total assistance with ADLs to avoid stress as much as possible. Because extremes of temperature should be avoided, measures to raise the body temperature, such as extra blankets and turning up the heat, should be avoided.

A client has been diagnosed with Cushing's syndrome. The nurse should assess the client for which expected manifestations of this disorder? 1. Dizziness 2. Weight loss 3. Hypoglycemia 4. Truncal obesity

4 The client with Cushing's syndrome may exhibit a number of different manifestations. These may include moon face, truncal obesity, and a "buffalo hump" fat pad. Other signs include hyperglycemia, hypernatremia, hypocalcemia, peripheral edema, hypertension, increased appetite, and weight gain. Dizziness is not part of the clinical picture for this disorder.

Which nursing measure would be effective in preventing complications in a client with Addison's disease? 1. Restricting fluid intake 2. Offering foods high in potassium 3. Checking family support systems 4. Monitoring the blood glucose

4 The decrease in cortisol secretion that characterizes Addison's disease can result in hypoglycemia. Therefore monitoring the blood glucose would detect the presence of hypoglycemia so that it can be treated early to prevent complications. Fluid intake should be encouraged to compensate for dehydration. Potassium intake should be restricted because of hyperkalemia. Option 3 is not a priority for this client.

The nurse is caring for a client with a diagnosis of Cushing's syndrome. Which expected signs and symptoms should the nurse monitor for? Select all that apply. 1. Anorexia 2. Dizziness 3. Weight loss 4. Moon face 5. Hypertension6. Truncal obesity

456 A client with Cushing's syndrome may exhibit a number of different manifestations. These could include moon face, truncal obesity, and a buffalo hump fat pad. Other signs include hypokalemia, peripheral edema, hypertension, increased appetite, and weight gain. Dizziness is not part of the clinical picture for this disorder.

The nurse should question a prescription for aminoglutethimide (Cytadren) in a patient with which condition? A. Addison's disease B. Adrenal malignancy C. Cushing's syndrome D. Metastatic breast cancer

A

When assessing for potential adverse effects of fludrocortisone (Florinef), the nurse monitors for signs and symptoms of which condition? A. Hypokalemia B. Hypovolemia C. Hyponatremia . Hypercalcemia

A

A patient who has been taking corticosteroids has developed a "moon face" and facial redness, and has many bruises on her arms. Which of these is the most appropriate nursing diagnosis? A. Risk for infection B. Imbalanced nutrition: Less than body requirements C. Deficient fluid volume D. Disturbed body image

D

Based on the nurse's knowledge of glucocorticoids, what instructions should be given for this drug? A. Take the medication every evening. B. Inform the patient that the drug can be taken with coffee. C. Advise that the drug does not have to be tapered before stopped. D. Advise to take drug with milk, other dairy products, or food.

D

When monitoring a patient who is taking corticosteroids, the nurse observes for which adverse effects? (Select all that apply) A. Fragile skin B. Hyperglycemia C. Nervousness D. Hypotension E. Weight loss F. Drowsiness

ABC

A nurse assesses clients with potential endocrine disorders. Which clients are at high risk for adrenal insufficiency? (SATA) a. A 22-year-old female with metastatic cancer b. A 43-year-old male with tuberculosis c. A 51-year-old female with asthma d. A 65-year-old male with gram-negative sepsis e. A 70-year-old female with hypertension

ABD Metastatic cancer, tuberculosis, and gram-negative sepsis are primary causes of adrenal insufficiency. Active tuberculosis is a contributing factor for syndrome of inappropriate antidiuretic hormone. Hypertension is a key manifestation of Cushing's disease. These are not risk factors for adrenal insufficiency.

The client is taking fludrocortisone (Florinef) for adrenal hypofunction. The nurse instructs the client to report which symptom while taking this drug? a) Anxiety b) Headache c) Nausea d) Weight loss

B A side effect of fludrocortisone is hypertension. New onset of headache should be reported, and the client's blood pressure should be monitored. Anxiety is not a side effect of fludrocortisone and is not associated with adrenal hypofunction. Nausea is associated with adrenal hypofunction; it is not a side effect of fludrocortisone. Sodium-related fluid retention and weight gain, not loss, are possible with fludrocortisone therapy.

Which conditions is aminoglutethimide (Cytadren) used to treat? (Select all that apply.) A. Thyroid cancer B. Adrenal cancer C. Testicular cancer D. Cushing's syndrome E. Metastatic breast cancer

BCE

Because corticosteroids may cause sodium retention, the nurse will closely monitor patients with which condition when administering corticosteroids? A. Diabetes mellitus B. Seizure disorders C. Heart failure D. Hyperthyroidism

C

a client is admitted to the intensive care unit with suspected pheochromocytoma. the client's vital signs are temperature of 99.6*F (37.5 C), blood pressure (BP) of 200/110 mm Hg, heart rate of 110/min, and respirations of 20/min. the client is sweating profusely and reports a severe headache. which prescription should the nurse implement first? a. draw labs to assess electrolyte panel b. give acetaminophen 650 mg by mouth as needed for headache c. place a fan in the client's room d. start nitroprusside infusion at 0.5mcg/kg/min

d. start nitroprusside infusion at 0.5mcg/kg/min hypertensive crisis puts the client at risk for stroke and so has the highest priority for treatment. nitroprusside (nitropress, nipride) is a vasodilator given via infusion and can be titrated to keep the BP within a desired parameter.

when caring for a client diagnosed with pheochromocytoma, what information should the nurse know when assisting with planning care? a. profound hypotension may occur b. excessive catecholamines are released c. the condition is not curable and is treated symptomatically d. hypoglycemia is the primary presenting symptom

b. excessive catecholamines are released pheochromocytoma is a catecholamine -producing tumor of the adrenal gland and causes secretion of excessive amounts of epinephrine and norepinephrine. HTN is the principal manifestation, and the client has episodes of a high blood pressure accompanied by pounding headaches. the excessive release of catecholamine also results in excessive conversion of glycogen into glucose in the liver. consequently, hyperglycemia and glycosuria occur during attacks. pheochromocytoma is curable. the primary treatment is surgical removal of one or both of the adrenal glands, depending on whether the tumor is unilateral or bilateral

For a client in addisonian crisis, it would be very risky for a nurse to administer: 1. potassium chloride. 2. normal saline solution. 3. hydrocortisone. 4. fludrocortisone.

1 Addisonian crisis results in hyperkalemia; therefore, administering potassium chloride is contraindicated. Because the client will be hyponatremic, normal saline solution is indicated. Hydrocortisone and fludrocortisone are both useful in replacing deficient adrenal cortex hormones.

When teaching a client with Cushing's syndrome about dietary changes, the nurse should instruct the client to increase intake of: 1. fresh fruits. 2. dairy products. 3. processed meats. 4. cereals and grains.

1 Cushing's syndrome causes sodium retention, which increases urinary potassium loss. Therefore, the nurse should advise the client to increase intake of potassium-rich foods, such as fresh fruit. The client should restrict consumption of dairy products, processed meats, cereals, and grains because they contain significant amounts of sodium.

The adrenal cortex is responsible for producing which substances? 1. Glucocorticoids and androgens 2. Catecholamines and epinephrine 3. Mineralocorticoids and catecholamines 4. Norepinephrine and epinephrine

1 The adrenal glands have two divisions, the cortex and medulla. The cortex produces three types of hormones: glucocorticoids, mineralocorticoids, and androgens. The medulla produces catecholamines — epinephrine and norepinephrine.

The client diagnosed with Addison's disease is being discharged. Which statement indicates the client needs more discharge teaching? 1. "I will be sure to keep my dose of steroid constant and not vary." 2. "I may have to take two forms of steroids to remain healthy." 3. "I will get weak and dizzy if I don't take my medication." 4. "I need to notify any new HCP of the medications I take."

1 The dose of corticosteroids may have to be increased during the stress of an infection or surgery. It is imperative that under these circumstances the client receives enough medication to replicate the body's own responses to stress.

Following a transsphenoidal hypophysectomy, the nurse should assess the client carefully for which condition? 1. Hypocortisolism 2. Hypoglycemia 3. Hyperglycemia 4. Hypercalcemia

1 The nurse should assess for hypocortisolism. Abrupt withdrawal of endogenous cortisol may lead to severe adrenal insufficiency. Steroids should be given during surgery to prevent hypocortisolism from occurring. Signs of hypocortisolism include vomiting, increased weakness, dehydration and hypotension. After the corticotropin-secreting tumor is removed, the client shouldn't be at risk for hyperglycemia. Calcium imbalance shouldn't occur in this situation.

The client diagnosed with Cushing's disease is prescribed alendronate to prevent osteoporosis. Which information should the clinic nurse teach? Select all that apply. 1. Take the medication and sit upright for 30 minutes. 2. Take the medication just before going to bed. 3. Take the medication with an antacid to alleviate gastric disturbances. 4. Take the medication at least 30 minutes before breakfast. 5. Take the medication with a full glass of water.

145

The client diagnosed with Cushing's disease is prescribed pantoprazole. Which statement is the scientific rationale for prescribing this medication? 1. Pantoprazole increases the client's ability to digest food. 2. Pantoprazole decreases the excess amounts of gastric acid. 3. Pantoprazole absorbs gastric acid and eliminates it in the bowel. 4. Pantoprazole coats the stomach and prevents ulcer formation.

2

Which nursing instruction should the nurse discuss with the client who is receiving glucocorticoids for Addison's disease? 1. Discuss the importance of tapering medications when discontinuing medication. 2. Explain the dose may need to be increased during times of stress or infection. 3. Instruct the client to take medication on an empty stomach with a glass of water. 4. Encourage the client to wear clean white socks when wearing tennis shoes.

2

he client has developed iatrogenic Cushing's disease. Which statement is the scientific rationale for the development of this diagnosis? 1. The client has an autoimmune problem causing the destruction of the adrenal cortex. 2. The client has been taking steroid medications for an extended period for another disease process. 3. The client has a pituitary gland tumor causing the adrenal glands to produce too much cortisol. 4. The client has developed an adrenal gland problem for which the health-care provider does not have an explanation.

2

The nurse is assessing a client with Cushing's syndrome. Which observation should the nurse report to the physician immediately? 1. Pitting edema of the legs 2. An irregular apical pulse 3. Dry mucous membranes 4. Frequent urination

2 Because Cushing's syndrome causes aldosterone overproduction, which increases urinary potassium loss, the disorder may lead to hypokalemia. Therefore, the nurse should immediately report signs and symptoms of hypokalemia, such as an irregular apical pulse, to the physician. Edema is an expected finding because aldosterone overproduction causes sodium and fluid retention. Dry mucous membranes and frequent urination signal dehydration, which isn't associated with Cushing's syndrome.

A client is transferred to a rehabilitation center after being treated in the hospital for a stroke. Because the client has a history of Cushing's syndrome (hypercortisolism) and chronic obstructive pulmonary disease (COPD), the nurse formulates a nursing diagnosis of: 1. Risk for imbalanced fluid volume related to excessive sodium loss. 2. Risk for impaired skin integrity related to tissue catabolism secondary to cortisol hypersecretion. 3. Ineffective health maintenance related to frequent hypoglycemic episodes secondary to Cushing's syndrome. 4. Decreased cardiac output related to hypotension secondary to Cushing's syndrome.

2 Cushing's syndrome causes tissue catabolism, resulting in thinning skin and connective tissue loss; along with immobility related to stroke, these factors increase this client's risk for impaired skin integrity. The exaggerated glucocorticoid activity in Cushing's syndrome causes sodium and water retention which, in turn, leads to edema and hypertension. Therefore, Risk for imbalanced fluid volume and Decreased cardiac output are inappropriate nursing diagnoses. Increased glucocorticoid activity also causes persistent hyperglycemia, eliminating Ineffective health maintenance related to frequent hypoglycemic episodes as an appropriate nursing diagnosis.

A client with a history of Addison's disease and flulike symptoms accompanied by nausea and vomiting over the past week is brought to the facility. When he awoke this morning, his wife noticed that he acted confused and was extremely weak. The client's blood pressure is 90/58 mm Hg, his pulse is 116 beats/minute, and his temperature is 101° F (38.3° C). A diagnosis of acute adrenal insufficiency is made. What would the nurse expect to administer by I.V. infusion? 1. Insulin 2. Hydrocortisone 3. Potassium 4. Hypotonic saline

2 Emergency treatment for acute adrenal insufficiency (Addisonian crisis) is I.V. infusion of hydrocortisone and saline solution. The client is usually given a dose containing hydrocortisone 100 mg I.V. in normal saline every 6 hours until the client's blood pressure returns to normal. Insulin isn't indicated in this situation because adrenal insufficiency is usually associated with hypoglycemia. Potassium isn't indicated because these clients are usually hyperkalemic. The client needs normal — not hypotonic — saline solution.

The client diagnosed with Addison's disease asks the nurse, "Why do I have to take fludrocortisone?" Which statement is the nurse's best response? 1. "It will keep you from getting high blood sugars." 2. "Fludrocortisone helps the body retain sodium." 3. "Fludrocortisone prevents muscle cramping." 4. "It stimulates the pituitary gland to secrete adrenocorticotropic hormone."

2 Fludrocortisone (Florinef) is a mineral corticosteroid. Mineral corticosteroids help the body to maintain the correct serum sodium levels. Florinef is the preferred medication for Addison's disease, primary hypoaldosteronism, and congenital adrenal hyperplasia when sodium wasting occurs.

A client with Cushing's disease is being admitted to the hospital after a stab wound to the abdomen. The nurse plans care and places highest priority on which potential problem? 1. Nervousness 2. Infection 3. Concern about appearance 4. Inability to care for self

2 The client with a stab wound has a break in the body's first line of defense against infection. The client with Cushing's disease is at great risk for infection because of excess cortisol secretion and subsequent impaired antibody function and decreased proliferation of lymphocytes. The client may also have a potential for the problems listed in the other options but these are not the highest priority at this time.

The client is admitted to rule out Cushing's syndrome. Which laboratory tests should the nurse anticipate being ordered? 1. Plasma drug levels of quinidine, digoxin, and hydralazine. 2. Plasma levels of ACTH and cortisol. 3. A 24-hour urine for metanephrine and catecholamine. 4. Spot urine for creatinine and white blood cells (WBCs).

2 adrenal gland secretes cortisol & pituitary gland scrte adrenocorticotropic hormone (ACTH), used by the body to stimulate the production of cortisol.

The client diagnosed with Cushing's disease has undergone a unilateral adrenalectomy. Which discharge instructions should the nurse discuss with the client? 1. Instruct the client to take the glucocorticoid and mineralocorticoid medications as prescribed. 2. Teach the client regarding sexual functioning and androgen replacement therapy. 3. Explain the signs and symptoms of infection and when to call the health-care provider. 4. Demonstrate turn, cough, and deep-breathing exercises the client should perform every two (2) hours.

3

Which of the following laboratory test results would suggest to the nurse that a client has a corticotropin-secreting pituitary adenoma? 1. High corticotropin and low cortisol levels 2. Low corticotropin and high cortisol levels 3. High corticotropin and high cortisol levels 4. Low corticotropin and low cortisol levels

3 A corticotropin-secreting pituitary tumor would cause high corticotropin and high cortisol levels. A high corticotropin level with a low cortisol level and a low corticotropin level with a low cortisol level would be associated with hypocortisolism. Low corticotropin and high cortisol levels would be seen if there was a primary defect in the adrenal glands.

The nurse is assessing a client with possible Cushing's syndrome. In a client with Cushing's syndrome, the nurse would expect to find: 1. hypotension. 2. thick, coarse skin. 3. deposits of adipose tissue in the trunk and dorsocervical area. 4. weight gain in arms and legs.

3 Because of changes in fat distribution, adipose tissue accumulates in the trunk, face (moonface), and dorsocervical areas (buffalo hump). Hypertension is caused by fluid retention. Skin becomes thin and bruises easily because of a loss of collagen. Muscle wasting causes muscle atrophy and thin extremities.

During the first 24 hours after a client is diagnosed with Addisonian crisis, which intervention should the nurse perform frequently? 1. Weigh the client. 2. Test urine for ketones. 3. Assess vital signs. 4. Administer oral hydrocortisone.

3 Because the client in Addisonian crisis is unstable, vital signs and fluid and electrolyte balance should be assessed every 30 minutes until he's stable. Daily weights are sufficient when assessing the client's condition. The client shouldn't have ketones in his urine, so there is no need to assess the urine for their presence. Oral hydrocortisone isn't administered during the first 24 hours in severe adrenal insufficiency.

A client with Cushing's syndrome verbalizes concern to the nurse regarding the appearance of the buffalo hump that has developed. Which response by the nurse is appropriate? 1. "Don't be concerned, this problem can be covered with clothing." 2. "This is permanent, but looks are deceiving and not that important." 3. "Usually, these physical changes slowly improve following treatment." 4. "Try not to worry about it. There are other things to be concerned about."

3 The client with Cushing's syndrome should be reassured that most physical changes resolve with treatment. Options 1, 2, and 4 are not therapeutic responses.

A client has been diagnosed with pheochromocytoma. Which clinical manifestation is most indicative of this condition? 1. Water loss 2. Bradycardia 3. Hypertension 4. Decreased cardiac output

3 The client with pheochromocytoma has a benign or malignant tumor in the adrenal medulla. Because the medulla secretes epinephrine and norepinephrine, the client will exhibit signs related to excesses of these catecholamines, including tachycardia, increased cardiac output, and increased blood pressure. Vasoconstriction of the renal arteries triggers the renin-angiotensin system, resulting in water reabsorption and retention.

The emergency department nurse is caring for a client in an Addisonian crisis. Which intervention should the nurse implement first? 1. Draw serum electrolyte levels. 2. Administer methylprednisolone IV. 3. Start an 18-gauge catheter with normal saline. 4. Ask the client what medications he or she is taking

3 The nurse must treat an Addisonian crisis as all other shock situations. An IV and fluid replacement are imperative to prevent or treat shock. This is the first action

A client with suspected Cushing's syndrome is scheduled for adrenal venography. A nurse has provided instructions to the client regarding the test. Which statement by the client indicates a need for further instruction? 1. "I need to sign an informed consent." 2. "The insertion site will be locally anesthetized." 3. "I will be placed in a high-sitting position for the test." 4. "I may feel a burning sensation after the dye is injected."

3 The test aids in determining whether signs and symptoms are caused by abnormalities in the adrenal gland. The nurse assesses the client for allergies to iodine before the test. The client is informed that the supine position is necessary to access the femoral vein. An informed consent form is required, the insertion site will be locally anesthetized, and the client will experience a transient burning sensation after the dye is injected.

The charge nurse of an intensive care unit is making assignments for the night shift.Which client should be assigned to the most experienced intensive care nurse? 1. The client diagnosed with respiratory failure who is on a ventilator and requiresfrequent sedation. 2. The client diagnosed with lung cancer and iatrogenic Cushing's disease with ABGsof pH 7.35, PaO2 88, PaCO2 44, and HCO3 22. 3. The client diagnosed with Addison's disease who is lethargic and has a BP of 80/45,P 124, and R 28. 4. The client diagnosed with hyperthyroidism who has undergone a thyroidectomytwo (2) days ago and has a negative Trousseau's sign.

3 This client has a low blood pressure and tachycardia. This client could be about to go into an Addisonian crisis, a potentially life-threatening condition. The most experienced nurse should care for this client.

A client with Addison's disease is scheduled for discharge after being hospitalized for an adrenal crisis. Which statements by the client would indicate that client teaching has been effective? (SATA) 1. "I have to take my steroids for 10 days." 2. "I need to weigh myself daily to be sure I don't eat too many calories." 3. "I need to call my doctor to discuss my steroid needs before I have dental work." 4. "I will call the doctor if I suddenly feel profoundly weak or dizzy." 5. "If I feel like I have the flu, I'll carry on as usual because this is an expected response." 6. "I need to obtain and wear a Medic Alert bracelet."

346 Dental work can be a cause of physical stress; therefore, the client's physician needs to be informed about the dental work and an adjusted dosage of steroids may be necessary. Fatigue, weakness, and dizziness are symptoms of inadequate dosing of steroid therapy; the physician should be notified if these symptoms occur. A Medic Alert bracelet allows health care providers to access the client's history of Addison's disease if the client is unable to communicate this information. A client with Addison's disease doesn't produce enough steroids, so routine administration of steroids is a lifetime treatment. Daily weights should be monitored to monitor changes in fluid balance, not calorie intake. Influenza is an added physical stressor and the client may require an increased dosage of steroids. The client shouldn't "carry on as usual."

Which clinical manifestation should the nurse expect to note when assessing a client with Addison's disease? 1. Edema 2. Obesity 3. Hirsutism 4. Hypotension

4 Common manifestations of Addison's disease include postural hypotension from fluid loss, syncope, muscle weakness, anorexia, nausea, vomiting, abdominal cramps, weight loss, depression, and irritability. The manifestations in options 1, 2, and 3 are not associated with Addison's disease.

A nursing student notes in the medical record that a client with Cushing's syndrome is experiencing body image disturbances. The need for additional education regarding this problem is identified when the nursing student suggests which nursing intervention? 1. Encouraging the client's expression of feelings 2. Evaluating the client's understanding of the disease process 3. Encouraging family members to share their feelings about the disease process 4. Evaluating the client's understanding that the body changes need to be dealt with

4 Evaluating the client's understanding that the body changes that occur in this disorder need to be dealt with is an inappropriate nursing intervention. This option does not address the client's feelings. Options 1, 2, and 3 are appropriate because they address the client and family feelings regarding the disorder.

A nurse is caring for a postoperative adrenalectomy client. Which of the following does the nurse specifically monitor for in this client? 1. Peripheral edema 2. Bilateral exophthalmos 3. Signs and symptoms of hypocalcemia 4. Signs and symptoms of hypovolemia

4 Following adrenalectomy, the client is at risk for hypovolemia. Aldosterone, secreted by the adrenal cortex, plays a major role in fluid volume balance by retaining sodium and water. A deficiency of adrenocortical hormones does not cause the clinical manifestations noted in options 1, 2, and 3.

A client with Addison's disease comes to the clinic for a follow-up visit. When assessing this client, the nurse should stay alert for signs and symptoms of: 1. calcium and phosphorus abnormalities. 2. chloride and magnesium abnormalities. 3. sodium and chloride abnormalities. 4. sodium and potassium abnormalities.

4 In Addison's disease, a form of adrenocortical hypofunction, aldosterone secretion is reduced. Aldosterone promotes sodium conservation and potassium excretion. Therefore, aldosterone deficiency increases sodium excretion, predisposing the client to hyponatremia, and inhibits potassium excretion, predisposing the client to hyperkalemia. Because aldosterone doesn't regulate calcium, phosphorus, chloride, or magnesium, an aldosterone deficiency doesn't affect levels of these electrolytes directly.

A 50-year-old man has been taking prednisone (Deltasone) as part of treatment for bronchitis. He notices that the dosage of the medication decreases. During a follow-up office visit, he asks the nurse why he must continue the medication and why he cannot just stop taking it now that the feels better. What is the rationale behind tapering the doses? A. Sudden discontinuation of the medication may result in adrenal insufficiency. B. The patient would experience withdrawal symptoms if the drug were discontinued abruptly. C. Cushing's syndrome may develop as a reaction to a sudden drop in serum cortisone levels. D. When the symptoms have started to disappear, lower dosages are needed.

A

A nurse cares for a client with a deficiency of aldosterone. Which assessment finding should the nurse correlate with this deficiency? a. Increased urine output b. Vasoconstriction c. Blood glucose of 98 mg/dL d. Serum sodium of 144 mEq/L

A Aldosterone, the major mineralocorticoid, maintains extracellular fluid volume. It promotes sodium and water reabsorption and potassium excretion in the kidney tubules. A client with an aldosterone deficiency will have increased urine output. Vasoconstriction is not related. These sodium and glucose levels are normal; in aldosterone deficiency, the client would have hyponatremia and hyperkalemia. Aldosterone, the major mineralocorticoid, maintains extracellular fluid volume. It promotes sodium and water reabsorption and potassium excretion in the kidney tubules. A client with an aldosterone deficiency will have increased urine output. Vasoconstriction is not related. These sodium and glucose levels are normal; in aldosterone deficiency, the client would have hyponatremia and hyperkalemia.

A client with iatrogenic Cushing's syndrome is a resident in a long-term care facility. Which nursing action included in the client's care would be best to delegate to unlicensed assistive personnel (UAP)? a) Assist with personal hygiene and skin care. b) Develop a plan of care to minimize risk for infection. c) Instruct the client on the reasons to avoid overeating. d) Monitor for signs and symptoms of fluid retention.

A Assisting a client with bathing and skin care is included in UAP scope of practice. It is not within their scope of practice to develop a plan of care, although they will play a very important role in following the plan of care. Client teaching requires a broad education and should not be delegated to UAP. Monitoring for signs and symptoms of fluid retention is part of client assessment, which requires a higher level of education and clinical judgment.

The nurse provides teaching for a patient receiving corticotropin. The nurse will instruct the patient to contact the provider if which condition occurs? a. Bruising b. Constipation c. Myalgia d. Nausea

A Ecchymosis is an adverse reaction to corticotropin and should be reported. Constipation and nausea are known side effects but are not serious. Myalgia is not common.

A client with pheochromocytoma is admitted for surgery. What does the nurse do for the admitting assessment? a) Avoids palpating the abdomen b) Monitors for pulmonary edema with a chest x-ray c) Obtains a 24-hour urine specimen on admission d) Places the client in a room with a roommate for distraction

A The abdomen must not be palpated in a client with pheochromocytoma because this action could cause a sudden release of catecholamines and severe hypertension. The tumor on the adrenal gland causes sympathetic hyperactivity, increasing blood pressure and heart rate, not pulmonary edema. A 24-hour urine collection will already have been completed to determine the diagnosis of pheochromocytoma. A client diagnosed with a pheochromocytoma may feel anxious as part of the disease process; providing a roommate for distraction will not reduce the client's anxiety.

A nurse is caring for a client who has pheochromocytoma. Which of the following actions should the nurse take? a. Elevated the head of the client's bed. b. Palpate the client's abdomen. c. Monitor the client for hypotension. d. Check the client's urine specific gravity.

A The nurse should elevate the head of the client's bed to reduce BP and abdominal pressure. Palpating the abdomen can cause release of catecholamines and increase BP. Hypertension is associated with pheochromocytoma, not hypotension. Urine specific gravity is monitored for client's who have DI or SIADH.

A client presents to the emergency department with a history of adrenal insufficiency. The following laboratory values are obtained: Na+ 130 mEq/L, K+ 5.6 mEq/L, and glucose 72 mg/dL. Which is the first request that the nurse anticipates? a) Administer insulin and dextrose in normal saline to shift potassium into cells. b) Give spironolactone (Aldactone) 100 mg orally. c) Initiate histamine2 (H2) blocker therapy with ranitidine for ulcer prophylaxis. d) Obtain arterial blood gases to assess for peaked T waves.

A This client is hyperkalemic. The nurse should anticipate a request to administer 20 to 50 units of insulin with 20 to 50 mg of dextrose in normal saline as an IV infusion to shift potassium into the cells. Spironolactone is a potassium-sparing diuretic that helps the body keep potassium, which the client does not need. Although H2 blocker therapy would be appropriate for this client, it is not the first priority. Arterial blood gases are not used to assess for peaked T waves associated with hyperkalemia; an electrocardiogram needs to be obtained instead.

5. Which statement is incorrect about pheochromocytoma? A. This condition can be trigger by eating foods high in Tyramine such as hamburger meat and spinach. B. Monoamine oxidase inhibitors can trigger signs and symptoms of pheochromocytoma. C. An adrenalectomy is the only surgical treatment for pheochromocytoma. D. Patients with pheochromocytoma are at risk for hypertensive crisis.

A. This condition can be trigger by eating foods high in Tyramine such as hamburger meat and spinach. This statement is incorrect because hamburger meat and spinach are not high in Tyramine....foods that are aged, pickled, and fermented (cheeses, red wine, smoke/dried meat, bananas, sauerkraut, chocolate) can trigger signs and symptoms of pheochromocytoma.

The nurse would recognize which of the following as a potential side effect of the glucocorticoid therapy in young children? A. Arthritis B. Growth suppression C. Constipation D. Iron-deficiency anemia

B

Under secretion of the adrenocortical hormones leads to: A. Cushing's syndrome B. Addison's disease

B

When discussing glucocorticoids to a patient, what statement by the nurse is accurate regarding the action of these medications? A. They decrease serum sodium and glucose levels. B. They regulate carbohydrate, fat, and protein metabolism. C. They stimulate defense mechanisms to produce immunity. D. They are produced in lower amounts during times of stress.

B

A patient with adrenocortical insufficiency is prescribed hydrocortisone. Which drugs should be avoided in the patient's prescription? a. Oral contraceptives, antiepileptics, and nonsteroidal antiinflammatory drugs (NSAIDs) b. Oral hypoglycemics, anticoagulants, and nonsteroidal antiinflammatory drugs (NSAIDs) c. Antihypertensives, oral hypoglycemics, and nonsteroidal antiinflammatory drugs (NSAIDs) d. Antiepileptics, antihypertensives, and oral hypoglycemics

B Hydrocortisone is a corticosteroid. Oral hypoglycemics, anticoagulants, and nonsteroidal antiinflammatory drugs (NSAIDs) have potential interactions with corticosteroids and should be avoided by a patient taking hydrocortisone. Note that antiepileptics and antihypertensives may or may not interact with corticosteroids.

A nurse cares for a client with adrenal hyperfunction. The client screams at her husband, bursts into tears, and throws her water pitcher against the wall. She then tells the nurse, "I feel like I am going crazy." How should the nurse respond? a. I will ask your doctor to order a psychiatric consult for you. b. You feel this way because of your hormone levels. c. Can I bring you information about support groups? d. I will close the door to your room and restrict visitors.

B Hypercortisolism can cause the client to show neurotic or psychotic behavior. The client needs to know that these behavior changes do not reflect a true psychiatric disorder and will resolve when therapy results in lower and steadier blood cortisol levels. The client needs to understand this effect and does not need a psychiatrist, support groups, or restricted visitors at this time.

Which finding is consistent with a diagnosis of hyperaldosteronism?Multiple choice question a. Edema b. Hypernatremia c. Low blood pressure d. Potassium retention

B In hyperaldosteronism, elevated levels of aldosterone are associated with sodium retention, which leads to hypernatremia. Edema and low blood pressure are not caused by an increase in sodium excretion. Elevated levels of aldosterone lead to potassium excretion.

A client presents to the emergency department with acute adrenal insufficiency and the following vital signs: P 118 beats/min, R 18 breaths/min, BP 84/44 mm Hg, pulse oximetry 98%, and T 98.8° F oral. Which nursing intervention is the highest priority for this client? a) Administering furosemide (Lasix) b) Providing isotonic fluids c) Replacing potassium losses d) Restricting sodium

B Providing isotonic fluid is the priority intervention because this client's vital signs indicate volume loss that may be caused by nausea and vomiting and may accompany acute adrenal insufficiency. Isotonic fluids will be needed to administer IV medications such as hydrocortisone. Furosemide is a loop diuretic, which this client does not need. Potassium is normally increased in acute adrenal insufficiency, but potassium may have been lost if the client has had diarrhea; laboratory work will have to be obtained. Any restrictions, including sodium, should not be started without obtaining laboratory values to establish the client's baseline.

A nurse teaches a client with a cortisol deficiency who is prescribed prednisone (Deltasone). Which statement should the nurse include in this client's instructions? a. You will need to learn how to rotate the injection sites. b. If you work outside in the heat, you may need another drug. c. You need to follow a diet with strict sodium restrictions. d. Take one tablet in the morning and two tablets at night.

B Steroid dosage adjustment may be needed if the client works outdoors and might be difficult, especially in hot weather, when the client is sweating a great deal more than normal. Clients take prednisone orally, have no need for a salt restriction, and usually start the regimen with two tablets in the morning and one at night

A patient is diagnosed with adrenocortical insufficiency. Which laboratory findings would be consistent with this diagnosis? Select all that apply. (SATA) a. Serum sodium: 140 mEq/L b. Serum potassium: 6.5 mEq/L c. Blood glucose levels: 80 mg/dL d. Blood urea nitrogen (BUN): 30 mg/dL e. Electrocardiogram (ECG): Peaked T waves

BCE Adrenocortical insufficiency leads to hyperkalemia, hypoglycemia, peaked T waves in ECG, hyponatremia, and increased blood urea nitrogen levels. Normal serum electrolyte ranges include sodium from 135 to 145 mEq/L, potassium from 3.5 to 5 mEq/L, glucose from 70 to 99 mg/dL, and blood urea nitrogen from 6 to 20 mg/dL. A serum potassium level of 6.5 mEq/L shows increased serum potassium levels (hyperkalemia). A blood urea nitrogen level of 30 mg/dL shows increased levels. Peaked T waves are observed in electrocardiogram due to hyperkalemia.

The nurse has a prescription for a patient to receive prednisone (Deltasone) to treat contact dermatitis. The nurse would question this prescription for this patient with what condition? A. Asthma B. Multiple sclerosis C. Acquired immune deficiency syndrome (AIDS) D. Chronic obstructive pulmonary disease

C

A client is hospitalized with a possible disorder of the adrenal cortex. Which nursing activity is best for the charge nurse to delegate to an experienced nursing assistant? A. Ask about risk factors for adrenocortical problems. B. Assess the client's response to physiologic stressors. C. Check the client's blood glucose levels every 4 hours. D. Teach the client how to do a 24-hour urine collection.

C Blood glucose monitoring is within the nursing assistant's scope of practice if the nursing assistant has received education and evaluation in the skill. Assessing risk factors for adrenocortical problems is not part of a nursing assistant's education. Assessing the client's response to physiologic stressors requires the more complex skill set of licensed nursing staff. Teaching the proper method for a 24-hour urine collection is a multi-step process; this task should not be delegated.

Which client does the nurse identify as being at highest risk for acute adrenal insufficiency resulting from corticosteroid use? a) Client with hematemesis, upper epigastric pain for the past 3 days not relieved with food, and melena b) Client with right upper quadrant pain unrelieved for the past 2 days, dark-brown urine, and clay-colored stools c) Client with shortness of breath and chest tightness, nasal flaring, audible wheezing, and oxygen saturation of 85% for the second time this week d) Client with three emergency department visits in the past month for edema, shortness of breath, weight gain, and jugular venous distention

C Corticosteroids may be used to treat signs and symptoms of asthma, such as shortness of breath and chest tightness, nasal flaring, audible wheezing, and oxygen saturation of 85%. This places the client at risk for adrenal insufficiency. Corticosteroids are not used to treat signs and symptoms of GI bleeding or peptic ulcer disease (hematemesis, upper epigastric pain for the past 3 days not relieved with food, and melena), gallbladder disease (right upper quadrant pain unrelieved for the past 2 days, dark brown urine, and clay-colored stools), or congestive heart failure (edema, shortness of breath, weight gain, and jugular venous distention).

A nurse plans care for a client with Cushing's disease. Which action should the nurse include in this client's plan of care to prevent injury? a. Pad the side rails of the client's bed. b. Assist the client to change positions slowly. c. Use a lift sheet to change the client's position. d. Keep suctioning equipment at the clients bedside.

C Cushing's syndrome or disease greatly increases the serum levels of cortisol, which contributes to excessive bone demineralization and increases the risk for pathologic bone fracture. Padding the side rails and assisting the client to change position may be effective, but these measures will not protect her as much as using a lift sheet. The client should not require suctioning.

A client with Cushing's disease begins to laugh loudly and inappropriately, causing the family in the room to be uncomfortable. What is the nurse's best response? a) "Don't mind this. The disease is causing this." b) "I need to check the client's cortisol level." c) "The disease can sometimes affect emotional responses." d) "Medication is available to help with this."

C The client may have neurotic or psychotic behavior as a result of high blood cortisol levels. Being honest with the family helps them to understand what is happening. Telling the family not to mind the laughter and that the disease is causing it is vague and minimizes the family's concern. This is the perfect opportunity for the nurse to educate the family about the disease. Cushing's disease is the hypersecretion of cortisol, which is abnormally elevated in this disease and, because the diagnosis has already been made, blood levels do not need to be redrawn. Telling the family that medication is available to help with inappropriate laughing does not assist them in understanding the cause of or the reason for the client's behavior.

4. A patient is admitted with uncontrolled hypertension and the doctor suspects pheochromoctyoma. On assessment, you note the blood pressure to be 196/120 and HR 130. The patient reports feeling very anxious, sweaty, and having palpations. What do you expect the doctor will order to confirm a diagnosis of pheochromocytoma? A. Urinalysis B. Urine culture C. 24-hour urine D. 8-hour urine

C. 24-hour urine A 24-hour urine is ordered to check for catecholamine and metanephrines (which are metabolites formed when the body breaks down catecholamines).

1. A patient is diagnosed with pheochromocytoma. From your nursing knowledge, you know that the patient will present with hypertension, sweating, and palpations due to excessive catecholamine production from the? A. Adrenal Cortex B. Adrenal Zona Fasciculata C. Adrenal Medulla D. Adrenal Glomerulosa

C. Adrenal Medulla The adrenal medulla secretes catecholamines.

The nurse is caring for a client with hypercortisolism. The nurse begins to feel the onset of a cold but still has 4 hours left in the shift. What does the nurse do? a) Asks another nurse to care for the client b) Monitors the client for cold-like symptoms c) Refuses to care for the client d) Wears a facemask when caring for the client

D A client with hypercortisolism will be immune-suppressed. Anyone with a suspected upper respiratory infection who must enter the client's room must wear a mask to prevent the spread of infection. Although asking another nurse to care for the client might be an option in some facilities, it is not generally realistic or practical. The nurse, not the client, feels the onset of the cold, so monitoring the client for cold-like symptoms is part of good client care for a client with hypercortisolism. Refusing to care for the client after starting care would be considered abandonment.

A client with a possible adrenal gland tumor is admitted for testing and treatment. Which nursing action is most appropriate for the charge nurse to delegate to the nursing assistant? a) Assess skin turgor and mucous membranes for hydration status. b) Discuss the dietary restrictions needed for 24-hour urine testing. c) Plan ways to control the environment that will avoid stimulating the client. d) Remind the client to avoid drinking coffee and changing position suddenly.

D Drinking caffeinated beverages and changing position suddenly are not safe for a client with a potential adrenal gland tumor because of the effects of catecholamines. Reminding the client about previous instructions is an appropriate role for a nursing assistant who may observe the client doing potentially risky activities. Client assessment, client teaching, and environment planning are higher-level skills that require the experience and responsibility of the RN, and are not within the scope of practice of the nursing assistant.

A client with Cushing's disease says that she has lost 1 pound. What does the nurse do next? a) Auscultates the lungs for crackles b) Checks urine for specific gravity c) Forces fluids d) Weighs the client

D Fluid retention with weight gain is more of a problem than weight loss in clients with Cushing's disease. Weighing the client with Cushing's disease is part of the nurse's assessment. Crackles in the lungs indicate possible fluid retention, which would cause weight gain, not weight loss. Urine specific gravity will help assess hydration status, but this would not be the next step in the client's assessment. Forcing fluids is not appropriate because usually excess water and sodium reabsorption cause fluid retention in the client with Cushing's disease.

A patient who takes high-dose aspirin to treat arthritis will need to take prednisone to treat an acute flare of symptoms. What action will the nurse perform? a. Observe the patient for hypoglycemia. b. Monitor closely for increased urine output. c. Observe the patient for hypotension. d. Request an order for enteric-coated aspirin.

D Glucocorticoids can increase gastric distress, so an enteric-coated aspirin product is indicated. Glucocorticoids increase the risk of hypoglycemia, fluid retention, and hypertension.

A female patient who is on drug therapy for hyperaldosteronism develops menstrual disorders. Which prescribed drug may be the cause of this condition? a. Spironolactone b. Amlodipine c. Dexamethasone d. Aminoglutethimide

A Spironolactone is a potassium-sparing diuretic given to patients with hyperaldosteronism to treat hyperkalemia. This drug can cause menstrual disorders in women. Amlodipine and dexamethasone both control high blood pressure. Aminoglutethimide is given to decrease aldosterone synthesis.

A nurse is reviewing a plan of care for a client with Addison's disease. The nurse notes that the client is at risk for dehydration and suggests nursing interventions that will prevent this occurrence. Which nursing intervention is an appropriate component of the plan of care? Select all that apply. 1. Encouraging fluid intake of at least 3000 mL/day 2. Encouraging an intake of low-protein foods 3. Monitoring for changes in mental status 4. Monitoring intake and output 5. Maintaining a low-sodium diet

134 The client at risk for deficient fluid volume should be encouraged to eat regular meals and snacks and to increase the intake of sodium, protein, and complex carbohydrates. Oral replacement of sodium losses is necessary, and maintenance of adequate blood glucose levels is required.

The nurse is developing a plan of care for a client with Addison's disease. The nurse has identified a problem of risk for deficient fluid volume and identifies nursing interventions that will prevent this occurrence. Which nursing interventions should the nurse include in the plan of care? (SATA) 1. Monitor for changes in mentation. 2. Encourage an intake of low-protein foods. 3. Encourage an intake of low-sodium foods. 4. Encourage fluid intake of at least 3000 mL per day. 5. Monitor vital signs, skin turgor, and intake and output.

145 The client at risk for deficient fluid volume should be encouraged to eat regular meals and snacks and to increase intake of sodium, protein, and complex carbohydrates and fluids. Oral replacement of sodium losses is necessary, and maintenance of adequate blood glucose levels is required. Mentation, vital signs, skin turgor and intake and output should be monitored for signs of fluid volume deficit.

A nurse is performing an admission assessment on a client with a diagnosis of pheochromocytoma. The nurse should assess for the major sign associated with pheochromocytoma by performing which action? 1. Obtaining the client's weight 2. Taking the client's blood pressure 3. Testing the client's urine for glucose 4. Palpating the skin for its temperature

2 Pheochromocytoma is a catecholamine-producing tumor. Hypertension is the major sign associated with pheochromocytoma. Taking the client's blood pressure would assess the blood pressure status. Weight loss, glycosuria, and diaphoresis are also clinical manifestations of pheochromocytoma, yet hypertension is the major sign.

The nurse is admitting a client diagnosed with primary adrenal cortex insufficiency (Addison's disease). Which clinical manifestations should the nurse expect to assess? 1. Moon face, buffalo hump, and hyperglycemia. 2. Hirsutism, fever, and irritability. 3. Bronze pigmentation, hypotension, and anorexia. 4. Tachycardia, bulging eyes, and goiter.

3

A nurse is preparing to provide instructions to a client with Addison's disease regarding diet therapy. The nurse understands that which of the following diets would likely be prescribed for this client? 1. Low-protein diet 2. Low-sodium diet 3. High-sodium diet 4. Low-carbohydrate diet

3 A high-sodium, high-complex carbohydrate, and high-protein diet will be prescribed for the client with Addison's disease. To prevent excess fluid and sodium loss, the client is instructed to maintain an adequate salt intake of up to 8 g of sodium daily and to increase salt intake during hot weather, before strenuous exercise, and in response to fever, vomiting, or diarrhea.

A client with hyperaldosteronism is being treated with spironolactone (Aldactone) before surgery. Which precautions does the nurse teach this client? a. Read the label before using salt substitutes. b. Do not add salt to your food when you eat. c. Avoid exposure to sunlight. d. Take Tylenol instead of aspirin for pain.

A Spironolactone is a potassium-sparing diuretic used to control potassium levels. Its use can lead to hyperkalemia. Although the goal is to increase the client's potassium, unknowingly adding potassium can cause complications. Some salt substitutes are composed of potassium chloride and should be avoided by clients on spironolactone therapy. Depending on the client, he or she may benefit from a low-sodium diet before surgery, but this may not be necessary. Avoiding sunlight and Tylenol is not necessary.

A nurse is caring for a client who was prescribed high-dose corticosteroid therapy for 1 month to treat a severe inflammatory condition. The client's symptoms have now resolved and the client asks, "When can I stop taking these medications?" How should the nurse respond? a. It is possible for the inflammation to recur if you stop the medication. b. Once you start corticosteroids, you have to be weaned off them. c. You must decrease the dose slowly so your hormones will work again. d. The drug suppresses your immune system, which must be built back up.

B One of the most common causes of adrenal insufficiency, a life-threatening problem, is the sudden cessation of long-term, high-dose corticosteroid therapy. This therapy suppresses the hypothalamic-pituitary-adrenal axis and must be withdrawn gradually to allow for pituitary production of adrenocorticotropic hormone and adrenal production of cortisol. Decreasing hormone therapy slowly ensures self-production of hormone, not hormone effectiveness. Building the client's immune system and rebound inflammation are not concerns related to stopping high-dose corticosteroids.

A nurse teaches a client with Cushings disease. Which dietary requirements should the nurse include in this clients teaching? (Select all that apply.) a. Low calcium b. Low carbohydrate c. Low protein d. Low calories e. Low sodium

BDE The client with Cushings disease has weight gain, muscle loss, hyperglycemia, and sodium retention. Dietary modifications need to include reduction of carbohydrates and total calories to prevent or reduce the degree of hyperglycemia. Sodium retention causes water retention and hypertension. Clients are encouraged to restrict their sodium intake moderately. Clients often have bone density loss and need more calcium. Increased protein intake will help decrease muscle loss.

The nurse would question a prescription for steroids in a patient with which condition? A. Asthma B. Spinal cord injury C. Diabetes mellitus D. Rheumatoid arthritis

C

3. A patient has excessive catecholamines in the urine. Which of the following signs and symptoms would the patient NOT exhibit? SELECT-ALL-THAT-APPLY: A. Tachycardia B. Anxiety C. Hypoglycemia D. Thermogenesis E. Decreased Basal Metabolic Rate

C. Hypoglycemia E. Decreased Basal Metabolic Rate The patient would have HYPERglycemia (not hypoglycemia) and INCREASED basal metabolic rate (not decreased).

In the preoperative holding area, the client who is scheduled to have an adrenalectomy for hypercortisolism is prescribed to receive cortisol by intravenous infusion. What is the nurse's best action? a. Request a "time-out" to determine whether this is a valid prescription. b. Ask the client whether he or she usually takes prednisone. c. Hold the dose because the client has a high cortisol level. d. Administer the drug as prescribed.

D Although the client has hypercortisolism, removal of the adrenal gland will stop the secretion of this important hormone that is essential for life. Further, the stress of surgery also increases the client's need for this hormone. Supplying the hormone throughout surgery prevents the complication (or at least reduces the risk for) acute adrenal crisis.

The nurse is teaching a patient with Addison's disease about corticosteroid therapy. The nurse should prioritize which of these teaching points?Multiple choice question a. "Plan a high-carbohydrate diet." b. "Increase your daily intake of sodium." c. "Decrease your daily intake of calcium." d. "Do not stop taking the medication abruptly."

D The patient should be instructed to not stop the medication abruptly because this can cause adverse side effects. Patients taking corticosteroids should not consume a high-carbohydrate diet, because corticosteroids increase blood sugar. Patients should also increase their daily intake of calcium to prevent bone loss due to the side effects of corticosteroids. Patients should also decrease, not increase, their daily intake of sodium to avoid fluid retention.

a nurse is caring for a client with pheochromocytoma. the client is scheduled for an adrenalectomy. during the preoperative period, the priority nursing action would be to monitor the: a. vital signs b. intake and output c. blood urea nitrogen (BUN) level d. urine for glucose and acetone

a. vital signs hypertension is the hallmark of pheochromocytoma. severe hypertension can precipitate a brain attack (stroke) or sudden blindness. although all of the options are accurate nursing interventions, the priority nursing action is to monitor the vital signs, particularly the blood pressure

a client is admitted with a diagnosis of pheochromocytoma. the nurse would monitor which of the following to detect the most common sign of pheochromocytoma? a. skin temperature b. blood pressure c. urine keytones d. weight

b. blood pressure HTN is the major symptom associated with pheochromocytoma and is monitored by taking the client's blood pressure. glycosuria, weight loss, and diaphoresis are other clinical manifestations of pheochromocytoma; however, HTN is the most common sign

a client is admitted with pheochromocytoma. the nurse assesses the client's blood pressure frequently. this is based on the knowledge that pheochromocytoma of the adrenal medulla releases excessive amounts of a. renin b. aldosterone c. catecholamines d. glucocorticoids

c. catecholamines

a nurse is caring for a client with pheochromocytoma. the client asks for a snack and something warm to drink. the appropriate choice for this client to meet nutritional needs would be which of the following? a. crackers with cheese and tea b. graham crackers and warm milk c. toast with peanut butter and cocoa d. vanilla wafers and coffee with cream and sugar

b. graham crackers and warm milk the client with pheochromocytoma needs to be provided with a diet that is high in vitamins, minerals, and calories. of particular importance is that food or beverages that contain caffeine (e.g., chocolate, coffee, tea, and cola) are prohibited

what is the most conclusive test for diagnosis of pheochromocytoma? a. CT scan b. MRI c. 24 hour urine sample d. Ultrasonography

c. 24 hour urine sample

pheochromocytoma disturbs the secretion of which hormones? a. TSH b. FSH c. epinephrine and norephinephrine d. ACTH

c. epinephrine and norepinephrine

which nursing action would be appropriate to implement when a client has a diagnosis of pheochromocytoma? a. weigh the client b. test the client's urine for glucose c. monitor the blood pressure d. palpate the client's skin to determine warmth

c. monitor the blood pressure Hypertension is the major symptom that is associated with pheochromocytoma. the blood pressure status is monitored by taking the client's blood pressure. glycosuria, weight loss, and diaphoresis are also clinical manifestations of pheochromocytoma, but hypertension is the major symptom.

a client with pheochromocytoma is scheduled for surgery and says to the nurse, " I'm not sure that surgery is the best thing to do." what response by the nurse is appropriate? a." I think you are making the right decision to have the surgery" b. "You are very ill. your health care provider has made the correct decision" c. "there is no reason to worry. your health care provider is a wonderful surgeon" d. "you have concerns about the surgical treatment for your condition"

d. "you have concerns about the surgical treatment for your condition"

A nurse is caring for a client with Addison's disease. The nurse checks the vital signs and determines that the client has orthostatic hypotension. The nurse determines that this finding relates to which of the following? 1. A decrease in cortisol release 2. A decreased secretion of aldosterone 3. An increase in epinephrine secretion 4. Increased levels of androgens

2 A decreased secretion of aldosterone results in a limited reabsorption of sodium and water; therefore the client experiences fluid volume deficit. A decrease in cortisol, an increase in epinephrine, and an increase in androgen secretion do not result in orthostatic hypotension.

An emergency nurse cares for a client who is experiencing an acute adrenal crisis. Which action should the nurse take first? a. Obtain intravenous access. b. Administer hydrocortisone succinate (Solu-Cortef). c. Assess blood glucose. d. Administer insulin and dextrose.

A All actions are appropriate for the client with adrenal crisis. However, therapy is given intravenously, so the priority is to establish IV access. Solu-Cortef is the drug of choice. Blood glucose is monitored hourly and treatment is provided as needed. Insulin and dextrose are used to treat any hyperkalemia.

The client has developed iatrogenic Cushing's disease. Which is a scientific rationalefor the development of this problem? 1. The client has an autoimmune problem that causes the destruction of the adrenalcortex. 2. The client has been taking steroid medications for an extended period for anotherdisease process. 3. The client has a pituitary gland tumor that causes the adrenal glands to produce toomuch cortisol. 4. The client has developed an adrenal gland problem for which the health-careprovider does not have an explanation.

2 Iatrogenic means that a problem has been caused by a medical treatment or procedure—in this case, treatment with steroids for another problem. Clients taking steroids over a period of time develop the clinical manifestations of Cushing's disease.Disease processes for which long-term steroids are prescribed include chronic obstructive pulmonary disease, cancer, and arthritis.

The nurse is admitting a client diagnosed with primary adrenal cortex insufficiency(Addison's disease). When assessing the client, which clinical manifestations would thenurse expect to find? 1. Moon face, buffalo hump, and hyperglycemia. 2. Hirsutism, fever, and irritability. 3. Bronze pigmentation, hypotension, and anorexia. 4. Tachycardia, bulging eyes, and goiter.

3 Bronze pigmentation of the skin, particularly of the knuckles and other areas of skincreases, occurs in Addison's disease.Hypotension and anorexia also occur withAddison's.

A preoperative client is scheduled for adrenalectomy to remove a pheochromocytoma. The nurse would most closely monitor which of the following items in the preoperative period? 1. Intake and output 2. Blood urea nitrogen (BUN) 3. Vital signs 4. Urine glucose and ketones

3 Hypertension is the hallmark of pheochromocytoma. Severe hypertension can precipitate a stroke or sudden blindness. Although all the items are appropriate nursing assessments for the client with pheochromocytoma, the priority is to monitor the vital signs, especially the blood pressure.

The nurse is instructing a client with Cushing's syndrome on follow-up care. Which of these client statements would indicate a need for further instruction? 1. "I should avoid contact sports." 2. "I should check my ankles for swelling." 3. "I need to avoid foods high in potassium." 4. "I need to check my blood glucose regularly."

3 Hypokalemia is a common characteristic of Cushing's syndrome, and the client is instructed to consume foods high in potassium. Clients with this condition experience activity intolerance, osteoporosis, and frequent bruising. Fluid volume excess results from water and sodium retention. Hyperglycemia is caused by an increased cortisol secretion.

The nurse is performing an assessment on a client with a diagnosis of Cushing's syndrome. Which should the nurse expect to note on assessment of the client? 1. Skin atrophy 2. The presence of sunken eyes 3. Drooping on 1 side of the face 4. A rounded "moonlike" appearance to the face

4 With excessive secretion of adrenocorticotropic hormone (ACTH) and chronic corticosteroid use, the person with Cushing's syndrome develops a rounded moonlike face; prominent jowls; red cheeks; and hirsutism on the upper lip, lower cheek, and chin. The remaining options are not associated with the assessment findings in Cushing's syndrome.

The charge nurse on the medical-surgical unit is making client assignments for the shift. Which client is the most appropriate to assign to an LPN/LVN? A. Client with Cushing's syndrome who requires orthostatic vital signs assessments B. Client with diabetes mellitus who was admitted with a blood glucose of 45 mg/dL C. Client with exophthalmos who has many questions about endocrine function D. Client with possible pituitary adenoma who has just arrived on the nursing unit

A An LPN/LVN will be familiar with Cushing's syndrome and the method for assessment of orthostatic vital signs. The client with a blood glucose of 45 mg/dL, the client with questions about endocrine function, and the client with a possible pituitary adenoma all have complex needs that require the experience and scope of practice of an RN.

A nurse cares for a client with chronic hypercortisolism. Which action should the nurse take? a. Wash hands when entering the room. b. Keep the client in airborne isolation. c. Observe the client for signs of infection. d. Assess the client's daily chest x-ray.

A Excess cortisol reduces the number of circulating lymphocytes, inhibits maturation of macrophages, reduces antibody synthesis, and inhibits production of cytokines and inflammatory chemicals. As a result, these clients are at greater risk of infection and may not have the expected inflammatory manifestations when an infection is present. The nurse needs to take precautions to decrease the client's risk. It is not necessary to keep the client in isolation. The client does not need a daily chest x-ray.

A nurse assesses a client who potentially has hyperaldosteronism. Which serum laboratory values should the nurse associate with this disorder? (SATA) a. Sodium: 150 mEq/L b. Sodium: 130 mEq/L c. Potassium: 2.5 mEq/L d. Potassium: 5.0 mEq/L e. pH: 7.28 f. pH: 7.50

ACF Aldosterone increases reabsorption of sodium and excretion of potassium. Hyperaldosteronism causes hypernatremia, hypokalemia, and metabolic alkalosis. Hyponatremia, hyperkalemia, and acidosis are manifestations of adrenal insufficiency.

A nurse assesses a client with Cushing's disease. Which assessment findings should the nurse correlate with this disorder? (SATA) a. Moon face b. Weight loss c. Hypotension d. Petechiae e. Muscle atrophy

ADE

a client admitted with a pheochromocytoma returns from the operating room after adrenalectomy. the nurse should carefully assess this client for: a. hypokalemia b. hyperglycemia c. marked sodium and water retention d. marked fluctuations in blood pressure

d. marked fluctuations in blood pressure pheochromocytoma is a tumor in the adrenal medulla that produces excess catecholamines (epinephrine and norepinephrine). an excess of these catecholamines can cause sever HTN. surgery (an adrenalectomy) cures the elevated blood pressure most of the time, but in as many as 30% of clients, HTN remains and must be monitored and treated

A nursing instructor asks a student to describe the pathophysiology that occurs in Cushing's disease. Which statement by the student indicates an accurate understanding of this disorder? 1. "Cushing's disease is characterized by an oversecretion of insulin." 2. "Cushing's disease is characterized by an oversecretion of glucocorticoid hormones." 3. "Cushing's disease is characterized by an undersecretion of corticotropic hormones." 4. "Cushing's disease is characterized by an undersecretion of glucocorticoid hormones."

2 Cushing's syndrome is characterized by an oversecretion of glucocorticoid hormones. Addison's disease is characterized by the failure of the adrenal cortex to produce and secrete adrenocortical hormones. Options 1 and 4 are inaccurate regarding Cushing's syndrome.

A nurse is reinforcing home care instructions to a client with a diagnosis of Cushing's syndrome. Which statement reflects a need for further client education? 1. "Taking my medications exactly as prescribed is essential." 2. "I need to read the labels on any over-the-counter medications I purchase." 3. "My family needs to be familiar with the signs and symptoms of hypoadrenalism." 4. "I could experience the signs and symptoms of hyperadrenalism because of Cushing's."

2 The client with Cushing's syndrome should be instructed to take the medications exactly as prescribed. The nurse should emphasize the importance of continuing medications, consulting with the health care provider before purchasing any over-the-counter medications, and maintaining regular follow-up care. The nurse should also instruct the client in the signs and symptoms of both hypoadrenalism and hyperadrenalism.

6. A patient is scheduled for a bilateral adrenalectomy. Preoperatively, the patient is ordered by the doctor to take an alpha-adrenergic blocker. After administering a dose of this medication, what type of side effect will you monitor the patient for? A. Bradypnea B. Hyperglycemia C. Reflex tachycardia D. Hypertension

C. Reflex tachycardia Alpha-adrenergic blockers (Cardura, Minipress, Hyrtin) block noradrenaline which reduces catecholamine. This will help decrease blood pressure and prevent hypertensive crisis during surgery. However, a side effect of this medication is reflex tachycardia due to the decrease in blood pressure. The heart will try to compensate by increasing the heart rate.

7. In regards to question 6, you are also educating the patient about the post-opt care for a bilateral adrenalectomy. Which statement by the patient indicates they understood your instructions? A. "I will have to take mineralocorticoids daily for 2 years." B. "I will have to take glucocorticoids and mineralocorticoids daily for 2 years." C. "When I experience signs of stress I will have to take mineralocorticoids as needed." D. "I will have to take glucocorticoids and mineralocorticoids daily for life."

D. "I will have to take glucocorticoids and mineralocorticoids daily for life." After a bilateral adrenalectomy, the patient will have to take glucocorticoids and mineralocorticoid for life. If the patient was having a unilateral adrenalectomy they would have to take glucocorticoids for approximately 2 years.

a priority expected outcome for a client with a pheochromocytoma is for the client to: a. verbalize coping mechanisms b. maintain a normotensive state c. maintain a decreased activity level d. demonstrate compliance with nutritional instruction

b. maintain a normotensive state a pheochromocytoma is a benign tumor of the adrenal gland in which the major manifestation is severe HTN due to excessive secretion of catecholamine, such as epinephrine. therefore, the priority goal for this client would be to maintain a normal blood pressure, or a normotensive state.

a nurse is caring for a client with pheochromocytoma. which data would indicate a potential complication associated with this disorder? a. urinary output of 50ml/hr b. a coagulation time of 5 min c. congestion heard on auscultation of the lungs d. a blood urea nitrogen (BUN) level of 20mg/dL

congestion heard on auscultation of the lungs the complications associated with pheochromocytoma include hypertensive retinopathy and nephropathy, myocarditis, congestive heart failure (CHF), increased platelet aggregation, and stroke. death can occur from shock, stroke, renal failure, dysrhythmias, or dissecting aortic aneurysm. congestion heard on auscultation of the lungs is indicative of CHF. a urinary output of 50ml/hr is an appropriate output; the nurse would become concerned if the output were less than 50ml/hr. a coagulation time of 5min is normal. a BUN level of 20mg/dl is a normal finding
