The nurse is planning postoperative care for a patient who is being admitted to the surgical unit from the recovery room after transsphenoidal resection of a pituitary tumor. Which nursing action would be included?

• Palpate extremities for edema.
• Measure urine volume every hour.
• Check hematocrit every 2 hours for 8 hours.
• Monitor continuous pulse oximetry for 24 hours. - ANSWER-

ANS: B

After pituitary surgery, the patient is at risk for diabetes insipidus caused by cerebral edema. Monitoring of urine output and urine specific gravity is essential. Hemorrhage is not a common problem. There is no need to check the hematocrit hourly. The patient is at risk for dehydration, not volume overload. The patient is not at high risk for problems with oxygenation, so continuous pulse oximetry is not needed.

The nurse is assessing a male patient diagnosed with a pituitary tumor causing panhypopituitarism. Which assessment finding is consistent with panhypopituitarism?

• High blood pressure
• Decreased facial hair
• Elevated blood glucose

d. Intermittent tachycardia - ANSWER-ANS: B

Changes in male secondary sex characteristics such as decreased facial hair, testicular atrophy, diminished spermatogenesis, loss of libido, impotence, and decreased muscle mass are associated with decreases in follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Fasting hypoglycemia and hypotension occur in panhypopituitarism because of decreases in adrenocorticotropic hormone (ACTH) and cortisol.Bradycardia is due to the decrease in thyroid-stimulating hormone (TSH) and thyroid hormones associated with panhypopituitarism.

Which information will the nurse include when teaching a 50- year-old male patient about somatropin (Genotropin)?

• The medication will be needed for 3 to 6 months.
• Inject the medication subcutaneously every evening. 2 / 4

• Blood glucose levels may decrease when taking the

medication.

• Stop taking the medication if swelling of the hands or feet

occurs. - ANSWER-ANS: B

Somatropin is injected subcutaneously daily, preferably in the evening. The patient will need to continue on somatropin for life. If swelling or other common adverse effects occur, the health care provider should be notified. Growth hormone will increase blood glucose levels.

Which finding indicates to the nurse that demeclocycline has been effective for a patient with syndrome of inappropriate antidiuretic hormone (SIADH)?

• Weight has increased.
• Urinary output has increased.
• Peripheral edema has increased.

d. Urine specific gravity has increased. - ANSWER-ANS: B

Demeclocycline blocks the action of antidiuretic hormone (ADH) on the renal tubules and increases urine output, producing more dilute urine. An increase in weight or an increase in urine specific gravity indicates that the SIADH is not corrected. Peripheral edema does not occur with SIADH. A sudden weight gain without edema is a common clinical manifestation of this disorder. 3 / 4

Which patient statement indicates to the nurse that further instruction is needed about chronic syndrome of inappropriate antidiuretic hormone (SIADH)?

• "I should weigh myself daily and report sudden weight loss or

gain."

• "I need to shop for foods low in sodium and avoid adding salt

to food."

• "I need to limit my fluid intake to no more than 1 quart of

liquids a day."

• "I should eat foods high in potassium because diuretics cause

potassium loss." - ANSWER-ANS: B

Patients with SIADH are at risk for hyponatremia, and a sodium supplement may be prescribed. The other patient statements are correct and indicate successful teaching has occurred.

A patient who is disoriented and reports a headache and muscle cramps is hospitalized with syndrome of inappropriate antidiuretic hormone (SIADH). Which initial laboratory result would the nurse expect?

• Elevated hematocrit
• Decreased serum sodium
• Increased serum chloride
