Pheochromocytoma
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 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
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
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
pheochromocytoma disturbs the secretion of which hormones? a. TSH b. FSH c. epinephrine and norephinephrine d. ACTH
c. epinephrine and norepinephrine
which is the most common symptom related to pheochromocytoma? a. pyuresis b. nausea and vomiting c. anxiety d. hypertension
d. hypertension
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
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
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
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 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
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 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
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 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 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.
