ANS: 1.6 A concentration of 125 mg in 2 mL will result in 100 mg in 1.6 mL.

20. Which finding for a patient who has hypothyroidism and hypertension indicates that the nurse should contact the health care provider before administering levothyroxine (Synthroid)? a. Increased thyroxine (T4) level b. Blood pressure 112/62 mm Hg c. Distant and difficult to hear heart sounds d. Elevated thyroid stimulating hormone level

ANS: A *An increased thyroxine level indicates the levothyroxine dose needs to be decreased. -The other data are consistent with hypothyroidism and the nurse should administer the levothyroxine. -DIF: Cognitive Level: Apply

23. Which finding indicates to the nurse that the current therapies are effective for a patient with acute adrenal insufficiency? a. Increasing serum sodium levels b. Decreasing blood glucose levels c. Decreasing serum chloride levels d. Increasing serum potassium levels

ANS: A *Clinical manifestations of Addison's disease include hyponatremia and an increase in sodium level indicates improvement. -The other values indicate that treatment has not been effective. -DIF: Apply (application)/Evaluation/Physiologic

26. The nurse providing care for a patient who has an adrenocortical adenoma causing hyperaldosteronism should a. monitor the blood pressure every 4 hours. b. elevate the patient's legs to relieve edema. c. monitor blood glucose level every 4 hours. d. order the patient a potassium-restricted diet.

ANS: A *Hypertension caused by sodium retention is a common complication of hyperaldosteronism. -Hyperaldosteronism does not cause an elevation in blood glucose. -The patient will be hypokalemic and require potassium supplementation before surgery. -Edema does not usually occur with hyperaldosteronism. DIF: Apply (application) /Implementation/NCLEX: Physiological Integrity

1. A young adult patient is being seen in the clinic with increased secretion of the anterior pituitary hormones. The nurse would expect the laboratory test results to show a. increased urinary cortisol. b. decreased serum thyroxine. c. elevated serum aldosterone levels. d. low urinary catecholamines excretion.

ANS: A *Increased secretion of adrenocorticotropic hormone (ACTH) by the anterior pituitary gland will lead to an increase in serum and urinary cortisol levels. -An increase, rather than a decrease, in thyroxine level would be expected with increased secretion of thyroid-stimulating hormone (TSH) by the anterior pituitary. -Aldosterone and catecholamine levels are not controlled by the anterior pituitary.

21. The nurse is caring for a 63-yr-old with a possible pituitary tumor who is scheduled for a computed tomography scan with contrast. Which information about the patient is important to discuss with the health care provider before the test? a. History of renal insufficiency b. Complains of chronic headache c. Recent bilateral visual field loss d. Blood glucose level of 134 mg/dL

ANS: A Because contrast media may cause acute kidney injury in patients with poor renal function, the health care provider will need to prescribe therapies such as IV fluids to prevent this complication. -The other findings are consistent with the patient's diagnosis of a pituitary tumor.

15. Which additional information will the nurse need to consider when reviewing the laboratory results for a patient's total calcium level? a. The blood glucose c. The phosphate level b. The serum albumin d. The magnesium level

ANS: B Part of the total calcium is bound to albumin, so hypoalbuminemia can lead to misinterpretation of calcium levels. -The other laboratory values will not affect total calcium interpretation.

25. A 29-yr-old woman with systemic lupus erythematosus has been prescribed 2 weeks of high-dose prednisone therapy. Which information about the prednisone is most important for the nurse to include? a. "Weigh yourself daily to monitor for weight gain." b. "The prednisone dose should be decreased gradually." c. "A weight-bearing exercise program will help minimize risk for osteoporosis." d. "Call the health care provider if you have mood changes with the prednisone."

ANS: B *Acute adrenal insufficiency may occur if exogenous corticosteroids are suddenly stopped. -Mood alterations and weight gain are possible adverse effects of corticosteroid use, but these are not life-threatening effects. ----------Osteoporosis occurs when patients take corticosteroids for longer periods.

19. The nurse is caring for a 45-yr-old male patient during a water deprivation test. Which finding is most important for the nurse to communicate to the health care provider? a. The patient complains of intense thirst. b. The patient has a 5-lb (2.3-kg) weight loss. c. The patient's urine osmolality does not increase. d. The patient feels dizzy when sitting on the edge of the bed.

ANS: B A drop in the weight of more than 2 kg indicates severe dehydration, and the test should be discontinued. -The other assessment data are not unusual with this test.

17. Which information about a patient who is scheduled for an oral glucose tolerance test should be reported to the health care provider before starting the test? a. The patient reports having occasional orthostatic dizziness. b. The patient takes oral corticosteroids for rheumatoid arthritis. c. The patient has had a 10-lb weight gain in the last month. d. The patient drank several glasses of water an hour previously.

ANS: B Corticosteroids can affect blood glucose results. -The other information will be provided to the health care provider but will not affect the test results.

13. A 62-yr-old patient with hyperthyroidism is to be treated with radioactive iodine (RAI). The nurse instructs the patient a. about radioactive precautions to take with all body secretions. b. that symptoms of hyperthyroidism should be relieved in about a week. c. that symptoms of hypothyroidism may occur as the RAI therapy takes effect. d. to discontinue the antithyroid medications taken before the radioactive therapy.

ANS: C *There is a high incidence of post-radiation hypothyroidism after RAI, and the patient should be monitored for symptoms of hypothyroidism. -RAI has a delayed response, with the maximum effect not seen for 2 to 3 months, and the patient will continue to take antithyroid medications during this time. -The therapeutic dose of radioactive iodine is low enough that no radiation safety precautions are needed.

15. An 82-yr-old patient in a long-term care facility is newly diagnosed with hypothyroidism. The nurse will need to consult with the health care provider before administering the prescribed a. docusate (Colace). c. diazepam (Valium). b. ibuprofen (Motrin). d. cefoxitin (Mefoxin).

ANS: C *Worsening of mental status and myxedema coma can be precipitated by the use of sedatives, especially in older adults. The nurse should discuss the use of diazepam with the health care provider before administration. -The other medications may be given safely to the patient. DIF: Cognitive Level: Apply (application)

5. A patient will be scheduled in the outpatient clinic for blood cortisol testing. Which instruction will the nurse provide? a. "Avoid adding any salt to your foods for 24 hours before the test." b. "You will need to lie down for 30 minutes before the blood is drawn." c. "Come to the laboratory to have the blood drawn early in the morning." d. "Do not have anything to eat or drink before the blood test is obtained."

ANS: C * *Cortisol levels are usually drawn in the morning, when levels are highest. -The other instructions would be given to patients who were having other endocrine testing.

38. Which information is most important for the nurse to communicate rapidly to the health care provider about a patient admitted with possible syndrome of inappropriate antidiuretic hormone (SIADH)? a. The patient has a recent weight gain of 9 lb. b. The patient complains of dyspnea with activity. c. The patient has a urine specific gravity of 1.025. d. The patient has a serum sodium level of 118 mEq/L.

ANS: D *A serum sodium of less than 120 mEq/L increases the risk for complications such as seizures and needs rapid correction. -The other data are not unusual for a patient with SIADH and do not indicate the need for rapid action.

22. A 44-yr-old female patient with Cushing syndrome is admitted for adrenalectomy. Which intervention by the nurse will be most helpful for the patient problem of disturbed body image related to changes in appearance? a. Reassure the patient that the physical changes are very common in patients with Cushing syndrome. b. Discuss the use of diet and exercise in controlling the weight gain associated with Cushing syndrome. c. Teach the patient that the metabolic impact of Cushing syndrome is of more importance than appearance. d. Remind the patient that most of the physical changes caused by Cushing syndrome will resolve after surgery.

ANS: D *The most reassuring and accurate communication to the patient is that the physical and emotional changes caused by the Cushing syndrome will resolve after hormone levels return to normal postoperatively. -Reassurance that the physical changes are expected or that there are more serious physiologic problems associated with Cushing syndrome are not therapeutic responses. -The patient's physiological changes are caused by the high hormone levels, not by the patient's diet or exercise choices. -DIF: Cognitive Level: Apply (application) / Implementation

42. Which finding by the nurse when assessing a patient with Hashimoto's thyroiditis and a goiter will require the most immediate action? a. New-onset changes in the patient's voice b. Elevation in the patient's T3 and T4 levels c. Resting apical pulse rate 112 beats/minute d. Bruit audible bilaterally over the thyroid gland

ANS: A Changes in the patient's voice indicate that the goiter is compressing the laryngeal nerve and may lead to airway compression. The other findings will also be reported but are expected with Hashimoto's thyroiditis and do not require immediate action.

1. Which statements will the nurse include when teaching a patient who is scheduled for oral glucose tolerance testing in the outpatient clinic (select all that apply)? a. "You will need to avoid smoking before the test." b. "Exercise should be avoided until the testing is complete." c. "Several blood samples will be obtained during the testing." d. "You should follow a low-calorie diet the day before the test." e. "The test requires that you fast for at least 8 hours before testing."

ANS: A, C, E Smoking may affect the results of oral glucose tolerance tests. -Blood samples are obtained at baseline and at 30, 60, and 120 minutes. Accuracy requires that the patient be fasting before the test. -The patient should consume at least 1500 calories/day for 3 days before the test. -The patient should be ambulatory and active for accurate test results.

6. A 61-yr-old female patient admitted with pneumonia has a total serum calcium level of 13.3 mg/dL (3.3 mmol/L). The nurse will anticipate the need to teach the patient about testing for (fill in the blank) levels. a. calcitonin b. catecholamine c. thyroid hormone d. parathyroid hormone

ANS: D *Parathyroid hormone (PTH) is the major controller of blood calcium levels. -Although calcitonin secretion is a counter-mechanism to PTH, it does not play a major role in calcium balance. -Catecholamine and thyroid hormone levels do not affect serum calcium level.

36. Which assessment finding of a 42-yr-old patient who had a bilateral adrenalectomy requires the most rapid action by the nurse? a. The blood glucose is 192 mg/dL. b. The lungs have bibasilar crackles. c. The patient reports 6/10 incisional pain. d. The blood pressure (BP) is 88/50 mm Hg.

ANS: D The decreased BP indicates possible adrenal insufficiency. The nurse should immediately notify the health care provider so that corticosteroid medications can be administered. The nurse should also address the elevated glucose, incisional pain, and crackles with appropriate collaborative or nursing actions, but prevention and treatment of acute adrenal insufficiency are the priorities after adrenalectomy.

7. The nurse determines that additional instruction is needed for a patient with chronic syndrome of inappropriate antidiuretic hormone (SIADH) when the patient makes which statement? a. "I need to shop for foods low in sodium and avoid adding salt to food." b. "I should weigh myself daily and report any sudden weight loss or gain." c. "I need to limit my fluid intake to no more than 1 quart of liquids a day." d. "I should eat foods high in potassium because diuretics cause potassium loss."

ANS: A 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.

32. The nurse is caring for a patient admitted with diabetes insipidus (DI). Which information is most important to report to the health care provider? a. The patient is confused and lethargic. b. The patient reports a recent head injury. c. The patient has a urine output of 400 mL/hr. d. The patient's urine specific gravity is 1.003.

ANS: A 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. -DIF: Cognitive Level: Analyze (analysis) REF: 1161 OBJ: Special Questions: Prioritization TOP: Nursing Process: Assessment MSC: NCLEX: Physiological Integrity

40. Which question will the nurse in the endocrine clinic ask to help determine a patient's risk factors for goiter? a. "How much milk do you drink?" b. "What medications are you taking?" c. "Are your immunizations up to date?" d. "Have you had any recent neck injuries?"

ANS: B *Medications that contain thyroid-inhibiting substances can cause goiter. -Milk intake, neck injury, and immunization history are not risk factors for goiter. -DIF: Understand (comprehension) /Assessment MSC: NCLEX: Physiological Integrity

8. A 56-yr-old patient who is disoriented and reports a headache and muscle cramps is hospitalized with possible syndrome of inappropriate antidiuretic hormone (SIADH). The nurse would expect the initial laboratory results to include a(n) a. elevated hematocrit. c. increased serum chloride. b. decreased serum sodium. d. low urine specific gravity.

ANS: B When water is retained, the serum sodium level will drop below normal, causing the clinical manifestations reported by the patient. -The hematocrit will decrease because of the dilution caused by water retention. -Urine will be more concentrated with a higher specific gravity. -The serum chloride level will usually decrease along with the sodium level. DIF: Cognitive Level: Understand (comprehension) REF: 1160 TOP: Nursing Process: Assessment MSC: NCLEX: Physiological Integrity

13. The nurse will plan to teach a patient to minimize physical and emotional stress while the patient is undergoing a. a water deprivation test. b. testing for serum T3 and T4 levels. c. a 24-hour urine test for free cortisol. d. a radioactive iodine (I-131) uptake test.

ANS: C Physical and emotional stress can affect the results of the free cortisol test. -The other tests are not impacted by stress.

3. A patient seen in the emergency department for severe headache and acute confusion has a serum sodium level of 118 mEq/L. The nurse will anticipate the need for which diagnostic test? a. Urinary 17-ketosteroids b. Antidiuretic hormone level c. Growth hormone stimulation test d. Adrenocorticotropic hormone level

ANS: B *Elevated levels of antidiuretic hormone will cause water retention and decrease serum sodium levels. -The other tests would not be helpful in determining possible causes of the patient's hyponatremia.

16. A patient is admitted with tetany. Which laboratory value should the nurse plan to monitor? a. Total protein c. Ionized calcium b. Blood glucose d. Serum phosphate

ANS: C Tetany is associated with hypocalcemia. -The other values would not be useful for this patient.

44. The cardiac telemetry unit charge nurse receives status reports from other nursing units about four patients who need cardiac monitoring. Which patient should be transferred to the cardiac unit FIRST? a. Patient with Hashimoto's thyroiditis and a heart rate of 102 b. Patient with tetany who has a new order for IV calcium chloride c. Patient with Cushing syndrome and a blood glucose of 140 mg/dL d. Patient with Addison's disease who takes hydrocortisone twice daily

ANS: B *Emergency treatment of tetany requires IV administration of calcium; electrocardiographic monitoring will be required because cardiac arrest may occur if high calcium levels result from too-rapid administration. -The information about the other patients indicates that they are more stable than the patient with tetany.

19. A patient who had radical neck surgery to remove a malignant tumor developed hypoparathyroidism. The nurse should plan to teach the patient about a. bisphosphonates to reduce bone demineralization. b. calcium supplements to normalize serum calcium levels. c. increasing fluid intake to decrease risk for nephrolithiasis. d. including whole grains in the diet to prevent constipation.

ANS: B *Oral calcium supplements are used to maintain the serum calcium in normal range and prevent the complications of hypocalcemia. - Whole grain foods decrease calcium absorption and will not be recommended. -Bisphosphonates will lower serum calcium levels further by preventing calcium from being reabsorbed from bone. -Kidney stones are not a complication of hypoparathyroidism and low calcium levels. -DIF: Cognitive Level: Apply (application)

27. The nurse will plan to monitor a patient diagnosed with a pheochromocytoma for : a. flushing. c. bradycardia. b. headache. d. hypoglycemia.

ANS: B *The classic clinical manifestations of pheochromocytoma are: hypertension, tachycardia, severe 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. -DIF: Cognitive Level: Apply (application) /Planning NCLEX: Physiological Integrity

35. A 37-yr-old patient has just arrived in the postanesthesia recovery unit (PACU) after a thyroidectomy. Which information about the patient is most important to communicate to the surgeon? a. Difficult to awaken. c. Reports 7/10 incisional pain. b. Increasing neck swelling. d. Cardiac rate 112 beats/minute.

ANS: B *The neck swelling may lead to respiratory difficulty, and rapid intervention is needed to prevent airway obstruction. -The incisional pain should be treated but is not unusual after surgery. -A heart rate of 112 beats/min is not unusual in a patient who has been hyperthyroid and has just arrived in the PACU from surgery. -Sleepiness in the immediate postoperative period is expected.

24. The nurse admits a patient to the hospital in Addisonian crisis. Which patient statement supports the need to plan additional teaching? a. "I frequently eat at restaurants, and my food has a lot of added salt." b. "I had the flu earlier this week, so I couldn't take the hydrocortisone." c. "I always double my dose of hydrocortisone on the days that I go for a long run." d. "I take twice as much hydrocortisone in the morning dose as I do in the afternoon."

ANS: B *The need for hydrocortisone replacement is increased with stressors such as illness, and the patient needs to be taught to call the health care provider because medication and IV fluids and electrolytes may need to be given. -The other patient statements indicate appropriate management of the Addison's disease.

17. A patient with primary hyperparathyroidism has a serum phosphorus level of 1.7 mg/dL (0.55 mmol/L) and calcium of 14 mg/dL (3.5 mmol/L). Which nursing action should be included in the plan of care? a. Restrict the patient to bed rest. b. Encourage 4000 mL of fluids daily. c. Institute routine seizure precautions. d. Assess for positive Chvostek's sign.

ANS: B *The patient with hypercalcemia is at risk for kidney stones, which may be prevented by a high fluid intake. -Seizure precautions and monitoring for Chvostek's or Trousseau's sign are appropriate for hypocalcemic patients. -The patient should engage in weight-bearing exercise to decrease calcium loss from bone. -DIF: Cognitive Level: Apply (application)

18. A patient develops carpopedal spasms and tingling of the lips following a parathyroidectomy. Which action will provide the patient with rapid relief from the symptoms? a. Administer the prescribed muscle relaxant. b. Have the patient rebreathe from a paper bag. c. Start the PRN O2 at 2 L/min per cannula. d. Stretch the muscles with passive range of motion.

ANS: B *The patient's symptoms suggest mild hypocalcemia. The symptoms of hypocalcemia will be temporarily reduced by having the patient breathe into a paper bag, which will raise the PaCO2 and create a more acidic pH. -Applying as-needed O2 or range of motion will have no impact on the ionized calcium level. -Calcium supplements will be given to normalize calcium levels quickly, but oral supplements will take time to be absorbed. -DIF: Cognitive Level: Apply (application)

7. During the nurse's physical examination of a young adult, the patient's thyroid gland cannot be felt. The most appropriate action by the nurse is to a. palpate the patient's neck more deeply. b. document that the thyroid was nonpalpable. c. notify the health care provider immediately. d. teach the patient about thyroid hormone testing.

ANS: B *The thyroid is frequently nonpalpable. The nurse should simply document the finding. -There is no need to notify the health care provider immediately about a normal finding. -There is no indication for thyroid-stimulating hormone (TSH) testing unless there is evidence of thyroid dysfunction. -Deep palpation of the neck is not appropriate.

16. A patient who was admitted with myxedema coma and diagnosed with hypothyroidism is improving. Discharge is expected to occur in 2 days. Which teaching strategy is likely to result in effective patient self-management at home? a. Delay teaching until closer to discharge date. b. Provide written reminders of information taught. c. Offer multiple options for management of therapies. d. Ensure privacy for teaching by asking the family to leave.

ANS: B *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. -Because 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. DIF: Cognitive Level: Apply (application)

1. A 40-yr-old patient with suspected acromegaly is seen at the clinic. To assist in making the diagnosis, which question should the nurse ask? a. "Have you had a recent head injury?" b. "Do you have to wear larger shoes now?" c. "Is there a family history of acromegaly?" d. "Are you experiencing tremors or anxiety?"

ANS: B Acromegaly causes an enlargement of the hands and feet. -Head injury and family history are not risk factors for acromegaly. -Tremors and anxiety are not clinical manifestations of acromegaly.

37. A patient is admitted with diabetes insipidus. Which action will be appropriate for the registered nurse (RN) to delegate to an experienced licensed practical/vocational nurse (LPN/LVN)? a. Titrate the infusion of 5% dextrose in water. b. Administer prescribed subcutaneous DDAVP. c. Assess the patient's overall hydration status every 8 hours. d. Teach the patient how to use desmopressin (DDAVP) nasal spray.

ANS: B Administration of medications is included in LPN/LVN education and scope of practice. Assessments, patient teaching, and titrating fluid infusions are more complex skills and should be done by the RN.

3. 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 should be included? a. Palpate extremities for edema. b. Measure urine volume every hour. c. Check hematocrit every 2 hours for 8 hours. d. Monitor continuous pulse oximetry for 24 hours.

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, and continuous pulse oximetry is not needed.

20. A patient with a possible pituitary adenoma is scheduled for a computed tomography (CT) scan with contrast media. Which patient information is important for the nurse to communicate to the health care provider before the test? a. Bilateral poor peripheral vision b. Allergies to iodine and shellfish c. Recent weight loss of 20 lb d. Complaint of ongoing headaches

ANS: B Because the usual contrast media is iodine-based, the health care provider will need to know about the allergy before the CT scan. -The other findings are common with any mass in the brain such as a pituitary adenoma.

4. The nurse is assessing a male patient diagnosed with a pituitary tumor causing panhypopituitarism. Assessment findings consistent with panhypopituitarism include a. high blood pressure b. decreased facial hair. c. elevated blood glucose. d. tachycardia and palpitations.

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 as a result of decreases in adrenocorticotropic hormone (ACTH) and cortisol. -Bradycardia is likely due to the decrease in thyroid-stimulating hormone (TSH) and thyroid hormones associated with panhypopituitarism.

6. The nurse determines that demeclocycline is effective for a patient with syndrome of inappropriate antidiuretic hormone (SIADH) based on finding that the patient's a. weight has increased. b. urinary output is increased. c. peripheral edema is increased. d. urine specific gravity is increased.

ANS: B Demeclocycline blocks the action of antidiuretic hormone (ADH) on the renal tubules and increases urine output. -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.

14. Which nursing assessment of a 70-yr-old patient is most important to make during initiation of thyroid replacement with levothyroxine (Synthroid)? a. Fluid balance c. Nutritional intake b. Apical pulse rate d. Orientation and alertness

ANS: B In older patients, initiation of levothyroxine therapy can increase myocardial oxygen demand and cause angina or dysrhythmias. The medication also is expected to improve mental status and fluid balance and will increase metabolic rate and nutritional needs, but these changes will not result in potentially life-threatening complications. DIF: Cognitive Level: Analyze (analysis)

18. A registered nurse (RN) is caring for a patient with a goiter and possible hyperthyroidism. Which action by the RN indicates that the charge nurse needs to provide the RN with additional teaching? a. The RN checks the blood pressure in both arms. b. The RN palpates the neck to assess thyroid size. c. The RN orders saline eye drops to lubricate the patient's bulging eyes. d. The RN lowers the thermostat to decrease the temperature in the room.

ANS: B Palpation can cause the release of thyroid hormones in a patient with an enlarged thyroid and should be avoided. -The other actions by the new RN are appropriate when caring for a patient with an enlarged thyroid.

5. Which information will the nurse include when teaching a 50-yr-old male patient about somatropin (Genotropin)? a. The medication will be needed for 3 to 6 months. b. Inject the medication subcutaneously every day. c. Blood glucose levels may decrease when taking the medication. d. Stop taking the medication if swelling of the hands or feet occurs.

ANS: B Somatropin is injected subcutaneously on a daily basis, 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.

12. Which nursing action will be included in the plan of care for a patient with Graves' disease who has exophthalmos? a. Place cold packs on the eyes to relieve pain and swelling. b. Elevate the head of the patient's bed to reduce periorbital fluid. c. Apply alternating eye patches to protect the corneas from irritation. d. Teach the patient to blink every few seconds to lubricate the corneas.

ANS: B The patient should sit upright as much as possible to promote fluid drainage from the periorbital area. -With exophthalmos, the patient is unable to close the eyes completely to blink. -Lubrication of the eyes, rather than eye patches, will protect the eyes from developing corneal scarring. -The swelling of the eye is not caused by excessive blood flow to the eye, so cold packs will not be helpful.

11. A patient who had a subtotal thyroidectomy earlier today develops laryngeal stridor and a cramp in the right hand upon returning to the surgical nursing unit. Which collaborative action will the nurse anticipate next? a. Suction the patient's airway. b. Administer IV calcium gluconate. c. Plan for emergency tracheostomy. d. Prepare for endotracheal intubation.

ANS: B The patient's clinical manifestations of stridor and cramping are consistent with tetany caused by hypocalcemia resulting from damage to the parathyroid glands during surgery. -Endotracheal intubation or tracheostomy may be needed if the calcium does not resolve the stridor. -Suctioning will not correct the stridor.

14. The nurse will teach a patient who is scheduled to complete a 24-hour urine collection for 17-ketosteroids to a. insert and maintain a retention catheter. b. keep the specimen refrigerated or on ice. c. drink at least 3 L of fluid during the 24 hours. d. void and save that specimen to start the collection.

ANS: B The specimen must be kept on ice or refrigerated until the collection is finished. Voided or catheterized specimens are acceptable for the test. The initial voided specimen is discarded. -There is no fluid intake requirement for the 24-hour collection.

11. A patient has been newly diagnosed with type 2 diabetes mellitus. Which information about the patient will be most useful to the nurse who is helping the patient develop strategies for successful adaptation to this disease? a. Ideal weight c. Activity level b. Value system d. Visual changes

ANS: B When dealing with a patient with a chronic condition such as diabetes, identification of the patient's values and beliefs can assist the interprofessional team in choosing strategies for successful lifestyle change. -The other information also will be useful but is not as important in developing an individualized plan for the necessary lifestyle changes.

39. After receiving change-of-shift report about the following four patients, which patient should the nurse assess first? a. A 31-yr-old female patient with Cushing syndrome and a blood glucose level of 244 mg/dL b. A 70-yr-old female patient taking levothyroxine (Synthroid) who has an irregular pulse of 134 c. A 53-yr-old male patient who has Addison's disease and is due for a prescribed dose of hydrocortisone (Solu-Cortef). d. A 22-yr-old male patient admitted with syndrome of inappropriate antidiuretic hormone (SIADH) who has a serum sodium level of 130 mEq/L

ANS: B --> "A 70-yr-old female patient taking levothyroxine (Synthroid) who has an irregular pulse of 134 " *Initiation of thyroid replacement in older adults may cause angina and cardiac dysrhythmias. The patient's high pulse rate needs rapid investigation by the nurse to assess for and intervene with any cardiac problems. -The other patients also require nursing assessment and/or actions but are not at risk for life-threatening complications. -DIF: Cognitive Level: Analyze (analysis) /OBJ: Special Questions: Prioritization | Special Questions: Multiple Patients /Assessment / NCLEX: Safe and Effective Care Environment

8. Which laboratory value should the nurse review to determine whether a patient's hypothyroidism is caused by a problem with the anterior pituitary gland or with the thyroid gland? a. Thyroxine (T4) level b. Triiodothyronine (T3) level c. Thyroid-stimulating hormone (TSH) level d. Thyrotropin-releasing hormone (TRH) level

ANS: C *A low TSH level indicates that the patient's hypothyroidism is caused by decreased anterior pituitary secretion of TSH. -Low T3and T4 levels are not diagnostic of the primary cause of the hypothyroidism. -TRH levels indicate the function of the hypothalamus.

31. The nurse is caring for a patient following an adrenalectomy. The highest priority in the immediate postoperative period is to a. protect the patient's skin. c. balance fluids and electrolytes. b. monitor for signs of infection. d. prevent emotional disturbances.

ANS: C *After adrenalectomy, the patient is at risk for circulatory instability caused by fluctuating hormone levels, and the focus of care is to assess and maintain fluid and electrolyte status through the use of IV fluids and corticosteroids. -The other goals are also important for the patient but are not as immediately life threatening as the circulatory collapse that can occur with fluid and electrolyte disturbances.

30. A patient has just arrived on the unit after a thyroidectomy. Which action should the nurse take first? a. Observe the dressing for bleeding. b. Check the blood pressure and pulse. c. Assess the patient's respiratory effort. d. Support the patient's head with pillows.

ANS: C *Airway obstruction is a possible complication after thyroidectomy because of swelling or bleeding at the site or tetany. The priority nursing action is to assess the airway. -The other actions are also part of the standard nursing care post-thyroidectomy but are not as high of a priority. -DIF:Analyze (analysis) /OBJ: Special Questions: Prioritization/Implementation /NCLEX: Physiological Integrity

9. An expected patient problem for a patient admitted to the hospital with symptoms of diabetes insipidus is a. excess fluid volume related to intake greater than output. b. impaired gas exchange related to fluid retention in lungs. c. sleep pattern disturbance related to frequent waking to void. d. risk for impaired skin integrity related to generalized edema.

ANS: C Nocturia occurs as a result of the polyuria caused by diabetes insipidus. -Edema, excess fluid volume, and fluid retention are not expected.

28. After a patient with a pituitary adenoma has had a hypophysectomy, the nurse will teach about the need for a. sodium restriction to prevent fluid retention. b. insulin to maintain normal blood glucose levels. c. oral corticosteroids to replace endogenous cortisol. d. chemotherapy to prevent malignant tumor recurrence.

ANS: C *Antidiuretic hormone (ADH), cortisol, and thyroid hormone replacement will be needed for life after hypophysectomy. -Without the effects of adrenocorticotropic hormone (ACTH) and cortisol, the blood glucose and serum sodium will be low unless cortisol is replaced. -An adenoma is a benign tumor, and chemotherapy will not be needed. DIF: Cognitive Level: Apply (application) /Planning NCLEX: Physiological Integrity

10. A patient is taking spironolactone (Aldactone), a drug that blocks the action of aldosterone on the kidney, for hypertension. The nurse will monitor for a. increased serum sodium. c. elevated serum potassium. b. decreased urinary output. d. evidence of fluid overload.

ANS: C *Because aldosterone increases the excretion of potassium, a medication that blocks aldosterone will tend to cause hyperkalemia. -Aldosterone also promotes the reabsorption of sodium and water in the renal tubules, so spironolactone will tend to cause: increased urine output, a decreased or normal serum sodium level, and signs of dehydration.

4. Which question from a nurse during a patient interview will provide focused information about a possible thyroid disorder? a. "What methods do you use to help cope with stress?" b. "Have you experienced any blurring or double vision?" c. "Have you had a recent unplanned weight gain or loss?" d. "Do you have to get up at night to empty your bladder?"

ANS: C *Because thyroid function affects metabolic rate, changes in weight may indicate hyperfunction or hypofunction of the thyroid gland. -Nocturia, visual difficulty, and changes in stress level are associated with other endocrine disorders.

21. A patient is being admitted with a diagnosis of Cushing syndrome. Which findings will the nurse expect during the assessment? a. Chronically low blood pressure b. Bronzed appearance of the skin c. Purplish streaks on the abdomen d. Decreased axillary and pubic hair

ANS: C *Purplish-red striae on the abdomen are a common clinical manifestation of Cushing syndrome. -Hypotension and bronzed-appearing skin are manifestations of Addison's disease. -Decreased axillary and pubic hair occur with androgen deficiency. -DIF: Understand (comprehension)/Assessment

29. Which intervention will the nurse include in the plan of care for a patient with syndrome of inappropriate antidiuretic hormone (SIADH)? a. Encourage fluids to 2 to 3 L/day. b. Monitor for increasing peripheral edema. c. Offer the patient hard candies to suck on. d. Keep head of bed elevated to 30 degrees.

ANS: C *Sucking on hard candies decreases thirst for a patient on fluid restriction. Patients with SIADH are on fluid restrictions of 800 to 1000 mL/day. -Peripheral edema is not seen with SIADH. - The head of the bed is elevated no more than 10 degrees to increase left atrial filling pressure and decrease antidiuretic hormone (ADH) release. DIF: Apply (application) /Planning NCLEX: Physiological Integrity

43. Which information obtained by the nurse in the endocrine clinic about a patient who has been taking prednisone 40 mg daily for 3 weeks is most important to report to the health care provider? a. Patient's blood pressure is 148/94 mm Hg. b. Patient has bilateral 2+ pitting ankle edema. c. Patient stopped taking the medication 2 days ago. d. Patient has not been taking the prescribed vitamin D.

ANS: C *Sudden cessation of corticosteroids after taking the medication for a week or more can lead to adrenal insufficiency, with problems such as severe hypotension and hypoglycemia. The patient will need immediate evaluation by the health care provider to prevent or treat adrenal insufficiency. -The other information will also be reported but does not require rapid treatment.

45. After obtaining the information shown in the accompanying figure regarding a patient with Addison's disease, which prescribed action will the nurse take first? a. Give 4 oz of fruit juice orally. b. Recheck the blood glucose level. c. Infuse 5% dextrose and 0.9% saline. d. Administer O2 therapy as needed.

ANS: C *The patient's poor skin turgor, hypotension, and hyponatremia indicate an Addisonian crisis. Immediate correction of the hypovolemia and hyponatremia is needed. -The other actions may also be needed but are not the initial action for the patient.

34. Which assessment finding for a 33-yr-old female patient admitted with Graves' disease requires the most rapid intervention by the nurse? a. Heart rate 136 beats/min b. Severe bilateral exophthalmos c. Temperature 103.8° F (40.4° C) d. Blood pressure 166/100 mm Hg

ANS: C *The patient's temperature indicates that the patient may have thyrotoxic crisis and that interventions to lower the temperature are needed immediately. -The other findings also require intervention but do not indicate potentially life-threatening complications. -DIF: Analyze (analysis) /OBJ: Special Questions: Prioritization /Assessment /NCLEX: Physiological Integrity

9. The nurse reviews a patient's glycosylated hemoglobin (A1C) results to evaluate a. fasting preprandial glucose levels. b. glucose levels 2 hours after a meal. c. glucose control over the past 90 days. d. hypoglycemic episodes in the past 3 months.

ANS: C Glycosylated hemoglobin testing measures glucose control over the last 3 months. Glucose testing before/after a meal or random testing may reveal impaired glucose tolerance and indicate prediabetes, but it is not done on patients who already have a diagnosis of diabetes. There is no test to evaluate for hypoglycemic episodes in the past.

10. Which information will the nurse teach a patient who has been newly diagnosed with Graves' disease? a. Exercise is contraindicated to avoid increasing metabolic rate. b. Restriction of iodine intake is needed to reduce thyroid activity. c. Antithyroid medications may take several months for full effect. d. Surgery will eventually be required to remove the thyroid gland.

ANS: C Medications used to block the synthesis of thyroid hormones may take 2 to 3 months before the full effect is seen. -Large doses of iodine are used to inhibit the synthesis of thyroid hormones. -Exercise using large muscle groups is encouraged to decrease the irritability and hyperactivity associated with high levels of thyroid hormones. -Radioactive iodine is the most common treatment for Graves' disease, although surgery may be used.

2. A patient is scheduled for transsphenoidal hypophysectomy to treat a pituitary adenoma. During preoperative teaching, the nurse instructs the patient about the need to a. cough and deep breathe every 2 hours postoperatively. b. remain on bed rest for the first 48 hours after the surgery. c. avoid brushing teeth for at least 10 days after the surgery. d. be positioned flat with sandbags at the head postoperatively.

ANS: C To avoid disruption of the suture line, the patient should avoid brushing the teeth for 10 days 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.

2. Which statement by a 50-yr-old female patient indicates to the nurse that further assessment of thyroid function may be necessary? a. "I notice my breasts are tender lately." b. "I am so thirsty that I drink all day long." c. "I get up several times at night to urinate." d. "I feel a lump in my throat when I swallow."

ANS: D *Difficulty in swallowing can occur with a goiter. -Nocturia is associated with diseases such as diabetes mellitus, diabetes insipidus, or chronic kidney disease. -Breast tenderness would occur with excessive gonadal hormone levels. -Thirst is a sign of disease such as diabetes.

33. Which prescribed medication should the nurse expect will have rapid effects on a patient admitted to the emergency department in thyroid storm? a. Iodine c. Propylthiouracil b. Methimazole d. Propranolol (Inderal)

ANS: D -Adrenergic blockers work rapidly to decrease the cardiovascular manifestations of thyroid storm. -The other medications take days to weeks to have an impact on thyroid function. -DIF: Apply (application) /Implementation/NCLEX: Physiological Integrity

12. An 18-yr-old male patient with small stature is scheduled for a growth hormone stimulation test. In preparation for the test, the nurse will obtain a. ice in a basin. b. glargine insulin. c. a cardiac monitor. d. 50% dextrose solution.

ANS: D Hypoglycemia is induced during the growth hormone stimulation test, and the nurse should be ready to administer 50% dextrose immediately. -Regular insulin is used to induce hypoglycemia (glargine is never given IV). -The patient does not require cardiac monitoring during the test. -Although blood samples for some tests must be kept on ice, this is not true for the growth hormone stimulation test.

41. Which finding by the nurse when assessing a patient with a large pituitary adenoma is most important to report to the health care provider? a. Changes in visual field c. Blood glucose 150 mg/dL b. Milk leaking from breasts d. Nausea and projectile vomiting

ANS: D Nausea and projectile vomiting may indicate increased intracranial pressure, which will require rapid actions for diagnosis and treatment. -Changes in the visual field, elevated blood glucose, and galactorrhea are common with pituitary adenoma, but these do not require rapid action to prevent life-threatening complications.
