Nokea
The nurse is caring for a patient with symptoms of diabetes insipidus who has been admitted to the hospital for evaluation and treatment. Which of the following nursing diagnoses is best for this patient?
- A. Insomnia related to frequent waking at night to void
- B. Impaired gas exchange related to fluid retention in lungs
- C. Excess fluid volume related to intake greater than output
- D. Risk for impaired skin integrity related to generalized edema
Correct Answer: A
Rationale: Nocturia occurs as a result of the polyuria caused by diabetes insipidus. Edema, excess fluid volume, and fluid retention are not expected.

The nurse is providing preoperative teaching for a patient scheduled for a hypophysectomy for treatment of a pituitary adenoma. Which of the following instructions should the nurse include in patient teaching?
- A. Cough and deep breathe every 2 hours postoperatively
- B. Bed rest for the first 24 hours after the surgery
- C. Be positioned flat with sandbags at the head postoperatively
- D. Have a NG tube after the surgery
Correct Answer: D
Rationale: The patient should be taught that they will have a NG tube after surgery. It is not necessary to remain on bed rest after this surgery. Coughing is discouraged because it may cause leakage of cerebrospinal fluid (CSF) from the suture line. The head of the bed should be elevated 30 degrees to reduce pressure on the sella turcica and decrease the risk for headaches.
The nurse is caring for a patient in a long-term care facility who has these medications prescribed. After the patient is diagnosed with hypothyroidism, which of the following medications should the nurse report to the health care provider?
- A. Docusate
- B. Diazepam
- C. Ibuprofen
- D. Cefoxitin
Correct Answer: B
Rationale: Worsening of mental status and myxedema coma can be precipitated by the use of sedatives, especially in older persons. The nurse should discuss the diazepam with the health care provider before administration. The other medications may be given safely to the patient.
The nurse is caring for a patient with hypertension who is diagnosed with a pheochromocytoma. Which of the following findings should the nurse monitor in the patient?
- A. Flushing
- B. Headache
- C. Bradycardia
- D. Hypoglycemia
Correct Answer: B
Rationale: The classic clinical manifestations of pheochromocytoma are hypertension, tachycardia, severe pounding headache, diaphoresis, and abdominal or chest pain. Elevated blood glucose may also occur because of sympathetic nervous system stimulation. Bradycardia and flushing would not be expected.
Which of the following information obtained by the nurse when caring for a patient who has diabetes insipidus (DI) is most important to report to the health care provider?
- A. History of a recent head injury
- B. Confusion and lethargy
- C. Urine output of 400 mL/hour
- D. Urine specific gravity is 1.003
Correct Answer: B
Rationale: The patient's confusion and lethargy may indicate hypernatremia and should be addressed quickly. In addition, patients with DI compensate for fluid losses by drinking copious amounts of fluids, but a patient who is lethargic will be unable to drink enough fluids and will become hypovolemic. A high urine output, low urine specific gravity, and history of a recent head injury are consistent with diabetes insipidus, but they do not require immediate nursing action to avoid life-threatening complications.
The nurse is planning teaching for a patient who was admitted with myxedema coma and diagnosed with hypothyroidism. Which of the following strategies is best for the nurse to use?
- A. Delay teaching until patient discharge.
- B. Ensure privacy by asking visitors to leave.
- C. Provide written handouts of all information.
- D. Offer multiple options for management of therapies.
Correct Answer: C
Rationale: Written instructions will be helpful to the patient because initially the hypothyroid patient may be unable to remember to take medications and other aspects of self-care. Since the treatment regimen is somewhat complex, teaching should be initiated well before discharge. Family members or friends should be included in teaching because the hypothyroid patient is likely to forget some aspects of the treatment plan. A simpler regimen will be easier to understand until the patient is euthyroid.
