MS chapter 49----10 Endocrine Problems

Question 1

A 40-year-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?”

Answer 1

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.

Question 2

A patient is scheduled for transsphenoidal hypophysectomy to treat a pituitary adenoma. What should the nurse include in
preoperative teaching?
a. Cough and deep breathe every 2 hours postoperatively.
b. Remain on bed rest for the first 48 hours postoperatively.
c. Avoid brushing teeth for at least 10 days after the surgery.
d. You will be positioned flat with a cervical collar after surgery.

Answer 2

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. A cervical collar is not needed.

Question 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.

Answer 3

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.

Question 4

The nurse is assessing a male patient diagnosed with a pituitary tumor causing panhypopituitarism. Which assessment finding is
consistent with panhypopituitarism?
a. High blood pressure
b. Decreased facial hair
c. Elevated blood glucose
d. Intermittent tachycardia

Answer 4

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.

Question 5

Which information will the nurse include when teaching a 50-year-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.

Answer 5

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.

Question 6

Which finding indicates to the nurse that demeclocycline is effective for a patient with syndrome of inappropriate antidiuretic
hormone (SIADH)?
a. Weight has increased.
b. Urinary output is increased.
c. Peripheral edema is increased.
d. Urine specific gravity is increased.

Answer 6

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.

Question 7

Which patient statement indicates to the nurse that additional instruction is needed for a patient with chronic syndrome of
inappropriate antidiuretic hormone (SIADH)?
a. “I should weigh myself daily and report sudden weight loss or gain.”
b. “I need to shop for foods low in sodium and avoid adding salt to food.”
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.”

Answer 7

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.

Question 8

A 56-year-old patient who is disoriented and reports a headache and muscle cramps is hospitalized with syndrome of inappropriate
antidiuretic hormone (SIADH). Which initial laboratory result should the nurse expect?
a. Elevated hematocrit
b. Decreased serum sodium
c. Increased serum chloride
d. Low urine specific gravity

Answer 8

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.

Question 9

Which problem should the nurse anticipate for a patient admitted to the hospital with diabetes insipidus?

a. Generalized edema
b. Fluid volume overload
c. Disturbed sleep pattern
d. Decreased gas exchange

Answer 9

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

Question 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.

Answer 10

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.

Question 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. Plan for emergency tracheostomy.
b. Administer IV calcium gluconate.
c. Prepare for endotracheal intubation.
d. Begin thyroid hormone replacement.

Answer 11

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. Thyroid hormone replacement may be needed eventually but will not improve the symptoms of hypocalcemia.

Question 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.

Answer 12

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.

Question 13

A patient who has hyperthyroidism is treated with radioactive iodine (RAI). What information should the nurse include in
discharge teaching?
a. Take radioactive precautions with all body secretions.
b. Symptoms of hyperthyroidism should be relieved in about a week.
c. Symptoms of hypothyroidism will occur as the RAI therapy takes effect.
d. Discontinue the antithyroid medications that were taken before the RAI therapy

Answer 13

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.

Question 14

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

Answer 14

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.

Question 15

An 82-year-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)
b. Ibuprofen (Motrin)
c. Diazepam (Valium)
d. Cefoxitin (Mefoxin)

Answer 15

ANS: C
Worsening of mental status and myxedema coma can be precipitated using 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.

Question 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.

Answer 16

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 complex, teaching should be started 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.

Question 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.

Answer 17

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.

Question 18

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

Answer 18

ANS: C
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.

Question 19

A patient who had radical neck surgery to remove a malignant tumor developed hypoparathyroidism. What topic should the nurse
plan to teach the patient?
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

Answer 19

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.

Question 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

Answer 20

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.

Question 21

A patient is being admitted with a diagnosis of Cushing syndrome. Which finding 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

Answer 21

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.

Question 22

A 44-year-old female patient with Cushing syndrome is admitted for adrenalectomy. Which intervention by the nurse will be 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.

Answer 22

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 minimize the patient’s concerns. The patient’s
physiological changes are caused by the high hormone levels, not by the patient’s diet or exercise choices.

Question 23

Which finding indicates to the nurse that the current therapies are effective for a patient who has acute adrenal insufficiency?

a. Increasing serum sodium levels
b. Decreasing blood glucose levels
c. Decreasing serum chloride levels
d. Increasing serum potassium levels

Answer 23

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.

Question 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.”

Answer 24

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.

Question 25

A 29-year-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.”

Answer 25

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.

Question 26

What action should the nurse take when providing care for a patient who has an adrenocortical adenoma causing
hyperaldosteronism?
a. Check blood glucose level every 4 hours.
b. Monitor the blood pressure every 4 hours.
c. Elevate the patient’s legs to relieve edema.
d. Order the patient a potassium-restricted diet.

Answer 26

ANS: B
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.

Question 27

What finding should the nurse plan to assess for in a patient diagnosed with a pheochromocytoma?

a. Flushing
b. Headache
c. Bradycardia
d. Hypoglycemia

Answer 27

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.

Question 28

What topic should the nurse teach a patient who had a pituitary adenoma after the hypophysectomy?

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

Answer 28

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.

Question 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.

Answer 29

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.

Question 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.

Answer 30

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 postthyroidectomy but are not as
high of a priority.

Question 31

The nurse is caring for a patient following an adrenalectomy. What is the highest priority in the immediate postoperative period?

a. Protecting the patient’s skin
b. Monitoring for signs of infection
c. Balancing fluids and electrolytes
d. Preventing emotional disturbances

Answer 31

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.

Question 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.

Answer 32

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.

Question 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
b. Methimazole
c. Propylthiouracil
d. Propranolol (Inderal)

Answer 33

ANS: D
β-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.

Question 34

Which assessment finding for an adult 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

Answer 34

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.

Question 35

A 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.
b. Increasing neck swelling.
c. Reports 7/10 incisional pain.
d. Cardiac rate 112 beats/min.

Answer 35

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.

Question 36

Which assessment finding in a 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.

Answer 36

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.

Question 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/VN)?
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 to use desmopressin (DDAVP) nasal spray.

Answer 37

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

Question 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 pounds.
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.

Answer 38

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.

Question 39

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

Answer 39

ANS: B
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.

Question 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. “Have you had a recent neck injury?”
d. “Are your immunizations up to date?”

Answer 40

ANS: B
Medications that contain thyroid-inhibiting substances can cause goiter. Milk intake, neck injury, and immunization history are not
risk factors for goiter

Question 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
b. Milk leaking from breasts
c. Blood glucose 150 mg/dL
d. Nausea and projectile vomiting

Answer 41

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.

Question 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/min
d. Bruit audible bilaterally over the thyroid gland

Answer 42

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.

Question 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.

Answer 43

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.

Question 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 IV hydrocortisone twice daily

Answer 44

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.

Question 45

A patient is to receive methylprednisolone (Solu-Medrol) 100 mg. The label on the medication states: methylprednisolone 125 mg
in 2 mL. How many milliliters will the nurse administer?

Answer 45

ANS:

1.6
