Hypo / Hyperthyroidism 2 Nclex

In the administration of a drug such as levothyroxine (Synthroid), the nurse should teach the client: A) That therapy typically lasts about 6 months. B) That weekly laboratory tests for T4 levels will be required. C) To report weight loss, anxiety, insomnia, and palpitations. D) That the drug may be taken every other day if diarrhea occurs.

C) To report weight loss, anxiety, insomnia, and palpitations. Weight loss, anxiety, insomnia and palpitations are signs of hyperthyroidism. An adjustment in dose would need to be obtained in order to reach a therapeutic level of levothyroxine (Synthroid) in the patient with hypothyroidism.

A nursing student is studying for a test on care of the client with endocrine disorders. Which of the following statements demonstrates an understanding of the difference between hyperthyroidism and hypothyroidism? a. "Deficient amounts of TH cause abnormalities in lipid metabolism, with decreased serum cholesterol and triglyceride levels." b. "Graves' disease is the most common cause of hypothyroidism." c. "Decreased renal blood flow and glomerular filtration rate reduces the kidney's ability to excrete water, which may cause hyponatremia." d. "Increased amounts of TH cause a decrease in cardiac output and peripheral blood flow."

Correct answer: c. "Decreased renal blood flow and glomerular filtration rate reduces the kidney's ability to excrete water, which may cause hyponatremia." Rationale: a. Is incorrect because deficient amounts of TH cause abnormalities in lipid metabolism with elevated serum cholesterol and triglyceride levels. b. Is incorrect because Graves' disease is the most common cause of hyperthyroidism, not hypothyroidism. d. Is incorrect because increased amounts of TH cause an increase in cardiac output and peripheral blood flow.

A patient with hyperthyroidism is taking propylthiouracil (PTU). The nurse will monitor the patient for: A) gingival hyperplasia and lycopenemia. B) dyspnea and a dry cough. C) blurred vision and nystagmus. D) fever and sore throat.

D) fever and sore throat. Fever and sore throat are signs of a serious adverse reaction in PTU and should be reported immediately.

After thyroidectomy, which of the following is the priority assessment to observe laryngeal nerve damage? a) hoarseness of voice b) difficulty in swallowing c) tetany d) fever

a) hoarseness of voice Laryngeal nerve damage is manifested by severe hoarseness of voice of "whispery voice".

A physician prescribes levothyroxine sodium (Synthroid), 0.15 mg orally daily, for a client with hypothyroidism. The nurse will prepare to administer this medication: a) in the morning to prevent insomnia b) only when the client complains of fatigue and cold intolerance c) at various times during the day to prevent tolerance from occurring d) three times daily in equal doses of 0.5 mg each to ensure consistent serum drug levels

a) in the morning to prevent insomnia Levothyroxine (Synthroid) is a synthetic thyroid hormone that increases cellular metabolism. Levothyroxine should be given in the morning in a single dose to prevent insomnia and should be given at the same time each day to maintain an adequate drug level. Therefore, options B, C, and D are incorrect.

Nurse Oliver should expect a client with hypothyroidism to report which health concerns? a. Increased appetite and weight loss b. Puffiness of the face and hands c. Nervousness and tremors d. Thyroid gland swelling

b. Puffiness of the face and hands Hypothyroidism (myxedema) causes facial puffiness, extremity edema, and weight gain. Signs and symptoms of hyperthyroidism (Graves' disease) include an increased appetite, weight loss, nervousness, tremors, and thyroid gland enlargement (goiter).

Nurse Ronn is assessing a client with possible Cushing's syndrome. In a client with Cushing's syndrome, the nurse would expect to find: a. Hypotension. b. Thick, coarse skin. c. Deposits of adipose tissue in the trunk and dorsocervical area. d. Weight gain in arms and legs.

c. Deposits of adipose tissue in the trunk and dorsocervical area Because of changes in fat distribution, adipose tissue accumulates in the trunk, face (moonface), and dorsocervical areas (buffalo hump). Hypertension is caused by fluid retention. Skin becomes thin and bruises easily because of a loss of collagen. Muscle wasting causes muscle atrophy and thin extremities.

A physician has prescribed propylthiouracil (PTU) for a client with hyperthyroidism and the nurse develops a plan of care for the client. A priority nursing assessment to be included in the plan regarding this medication is to assess for: a) relief of pain b) signs of renal toxicity c) signs and symptoms of hyperglycemia d) signs and symptoms of hypothyroidism

d) signs and symptoms of hypothyroidism Excessive dosing with propylthiouracil (PTU) may convert the client from a hyperthyroid state to a hypothyroid state. If this occurs, the dosage should be reduced. Temporary administration of thyroid hormone may be required. Propylthiouracil is not used for pain and does not cause hyperglycemia or renal toxicity.

The nurse is planning care for a client with hyperthyroidism. Which of the following nursing interventions are appropriate? Select all that apply a) instill isotonic eye drops as necessary b) provide several, small, well-balanced meals c) provide rest periods d) keep environment warm e) encourage frequent visitors and conversation f) weigh the client daily

a, b, c, and f (a) The client with hyperthyroidism may experience exopthalmos. This requires instillation of eye drops to prevent dryness and ulceration of the cornea. (b and f) The client experiences weight loss because of hypermetabolism. Several, small, well-balanced meals are given to improve nutritional status of the client and daily weights should be monitored. Weight is the most objective indicator of nutritional status. (c) The client is usually exhausted due to restlessness and agitation. Frequent rest periods help the client regain energy.

A female client with Cushing's syndrome is admitted to the medical-surgical unit. During the admission assessment, nurse Tyzz notes that the client is agitated and irritable, has poor memory, reports loss of appetite, and appears disheveled. These findings are consistent with which problem? a. Depression b. Neuropathy c. Hypoglycemia d. Hyperthyroidism

a. Depression Agitation, irritability, poor memory, loss of appetite, and neglect of one's appearance may signal depression, which is common in clients with Cushing's syndrome. Neuropathy affects clients with diabetes mellitus — not Cushing's syndrome. Although hypoglycemia can cause irritability, it also produces increased appetite, rather than loss of appetite. Hyperthyroidism typically causes such signs as goiter, nervousness, heat intolerance, and weight loss despite increased appetite.

Which outcome indicates that treatment of a male client with diabetes insipidus has been effective? a. Fluid intake is less than 2,500 ml/day. b. Urine output measures more than 200 ml/hour. c. Blood pressure is 90/50 mm Hg. d. The heart rate is 126 beats/minute.

a. Fluid intake is less than 2,500 ml/day Diabetes insipidus is characterized by polyuria (up to 8 L/day), constant thirst, and an unusually high oral intake of fluids. Treatment with the appropriate drug should decrease both oral fluid intake and urine output. A urine output of 200 ml/hour indicates continuing polyuria. A blood pressure of 90/50 mm Hg and a heart rate of 126 beats/minute indicate compensation for the continued fluid deficit, suggesting that treatment hasn't been effective.

A patient is admitted to the hospital with a diagnosis of Cushing syndrome. On physical assessment of the patient, the nurse would expect to find a. HTN, peripheral edema, and petechiae b. weight loss, buffalo hump, and moon face with acne c. abdominal and buttock striae, truncal obesity, and hypotension d. anorexia, signs of dehydration, and hyper pigmentation of the skin

a. HTN, peripheral edema, and petechiae (rationale- The effects of glucocorticoid excess include weight gain from accumulation and redistribution of adipose tissue, sodium and water retention, glucose intolerance, protein wasting, loss of bone structure, loss of collagen, and capillary fragility. Clinical manifestations of corticosteroid deficiency include hypotension, dehydration, weight loss, and hyperpigmentation of the skin.)

For the first 72 hours after thyroidectomy surgery, nurse Jamie would assess the female client for Chvostek's sign and Trousseau's sign because they indicate which of the following? a. Hypocalcemia b. Hypercalcemia c. Hypokalemia d. Hyperkalemia

a. Hypocalcemia The client who has undergone a thyroidectomy is at risk for developing hypocalcemia from inadvertent removal or damage to the parathyroid gland. The client with hypocalcemia will exhibit a positive Chvostek's sign (facial muscle contraction when the facial nerve in front of the ear is tapped) and a positive Trousseau's sign (carpal spasm when a blood pressure cuff is inflated for a few minutes). These signs aren't present with hypercalcemia, hypokalemia, or hyperkalemia.

The nurse is caring for a client who is about to undergo an adrenalectomy. Which of the following Preoperative interventions is most appropriate for this client? a. Maintain careful use of medical and surgical asepsis when providing care and treatments. b. Teach the client about a diet high in sodium to correct any potential sodium imbalances preoperatively. c. Explain to the client that electrolytes and glucose levels will be measured postoperatively. d. Teach the client how to effectively cough and deep breathe once surgery is complete.

a. Maintain careful use of medical and surgical asepsis when providing care and treatments. Use careful medical and surgical asepsis when providing care and treatments since Cortisol excess increases the risk of infection.

A nurse on a general medical-surgical unit is caring for a client with Cushing's syndrome. Which of the following statements is correct about the medication regimen for Cushing's syndrome? a. Mitotane is used to treat metastatic adrenal cancer. b. Aminogluthimide may be administered to clients with ectopic ACTH-secreting tumors before surgery is performed. c. Ketoconazole increases cortisol synthesis by the adrenal cortex. d. Somatostatin analog increases ACTH secretion in some clients.

a. Mitotane is used to treat metastatic adrenal cancer. Mitotane directly suppresses activity of the adrenal cortex and decreases peripheral metabolism of corticosteroids. It is used to treat metastatic adrenal cancer. b. Is incorrect because aminogluthimide may be administered to clients with ectopic ACTH-secreting tumors that cannot be surgically removed. c. Is incorrect because ketoconazole inhibits, not increases, cortisol synthesis by the adrenal cortex. d. Is incorrect because somatostatin suppresses, not increases, ACTH secretion.

Nurse Troy is aware that the most appropriate for a client with Addison's disease? a. Risk for infection b. Excessive fluid volume c. Urinary retention d. Hypothermia

a. Risk for infection Addison's disease decreases the production of all adrenal hormones, compromising the body's normal stress response and increasing the risk of infection. Other appropriate nursing diagnoses for a client with Addison's disease include Deficient fluid volume and Hyperthermia. Urinary retention isn't appropriate because Addison's disease causes polyuria.

In a 29-year-old female client who is being successfully treated for Cushing's syndrome, nurse Lyzette would expect a decline in: a. Serum glucose level. b. Hair loss. c. Bone mineralization. d. Menstrual flow.

a. Serum glucose level. Hyperglycemia, which develops from glucocorticoid excess, is a manifestation of Cushing's syndrome. With successful treatment of the disorder, serum glucose levels decline. Hirsutism is common in Cushing's syndrome; therefore, with successful treatment, abnormal hair growth also declines. Osteoporosis occurs in Cushing's syndrome; therefore, with successful treatment, bone mineralization increases. Amenorrhea develops in Cushing's syndrome. With successful treatment, the client experiences a return of menstrual flow, not a decline in it.

Nurse Louie is developing a teaching plan for a male client diagnosed with diabetes insipidus. The nurse should include information about which hormone lacking in clients with diabetes insipidus? a. antidiuretic hormone (ADH). b. thyroid-stimulating hormone (TSH). c. follicle-stimulating hormone (FSH). d. luteinizing hormone (LH).

a. antidiuretic hormone (ADH). ADH is the hormone clients with diabetes insipidus lack. The client's TSH, FSH, and LH levels won't be affected.

When caring for a male client with diabetes insipidus, nurse Juliet expects to administer: a. vasopressin (Pitressin Synthetic) b. furosemide (Lasix). c. regular insulin. d. 10% dextrose.

a. vasopressin (Pitressin Synthetic) Because diabetes insipidus results from decreased antidiuretic hormone (vasopressin) production, the nurse should expect to administer synthetic vasopressin for hormone replacement therapy. Furosemide, a diuretic, is contraindicated because a client with diabetes insipidus experiences polyuria. Insulin and dextrose are used to treat diabetes mellitus and its complications, not diabetes insipidus.

Which of the following assessment findings characterize thyroid storm? a) increased body temperature, decreased pulse, and increased blood pressure b) increased body temperature, increased pulse, and increased blood pressure c) increased body temperature, decreased pulse, and decreased blood pressure d) increased body temperature, increased pulse, and decreased blood pressure

b) increased body temperature, increased pulse, and increased blood pressure Thyroid storm is characterized by SNS activation. Thyroid hormones potentiate effects of cathecolamines (epinephrine/norepinephrine). Therefore, all vital signs will be increased.

A client newly diagnosed with Addison's disease is giving a return explanation of teaching done by the primary nurse. Which of the following statements indicates that further teaching is necessary? a. "I need to increase how much I drink each day." b. "I need to weigh myself if I think I am losing or gaining weight." c. "I need to maintain a diet high in sodium and low in potassium." d. "I need to take my medications each day."

b. "I need to weigh myself if I think that I am losing or gaining weight." The client is at risk for ineffective therapeutic regimen management. Clients with Addison's disease must learn to provide lifelong self-care that involves varied components: medications, diet, and recognizing and responding to stress. Changes in lifestyle are difficult to maintain permanently. The client needs to take the medications on a daily basis. The client needs to perform daily weights to monitor for signs of dehydration. The client needs to maintain a diet high in sodium and low in potassium, as well as maintain an increased fluid intake.

Which of these signs suggests that a male client with the syndrome of inappropriate antidiuretic hormone (SIADH) secretion is experiencing complications? a. Tetanic contractions b. Neck vein distention c. Weight loss d. Polyuria

b. Neck vein distention SIADH secretion causes antidiuretic hormone overproduction, which leads to fluid retention. Severe SIADH can cause such complications as vascular fluid overload, signaled by neck vein distention. This syndrome isn't associated with tetanic contractions. It may cause weight gain and fluid retention (secondary to oliguria).

A client presents to the emergency room with a history of Graves' disease. The client reports having symptoms for a few days, but has not previously sought or received any additional treatment. The client also reports having had a cold a few days back. Which of the following interventions would be appropriate to implement for this client, based on the history and current symptoms? Select all that apply. a. Administer aspirin b. Replace intravenous fluids c. Induce shivering d. Relieve respiratory distress e. Administer a cooling blanket

b. Replace intravenous fluids c. Induce shivering d. Relieve respiratory distress e. Administer a cooling blanket Rapid treatment of thyroid storm is essential to preserve life. Treatment includes cooling without aspirin (which increases free TH) or inducing shivering, replacing fluids, glucose, and electrolytes, relieving respiratory distress, stabilizing cardiovascular function, and reducing TH synthesis and secretion. #1 is incorrect because cooling happens without the use of aspirin. All of the other choices are correct.

Early this morning, a female client had a subtotal thyroidectomy. During evening rounds, nurse Tina assesses the client, who now has nausea, a temperature of 105° F (40.5° C), tachycardia, and extreme restlessness. What is the most likely cause of these signs? a. Diabetic ketoacidosis b. Thyroid crisis c. Hypoglycemia d. Tetany

b. Thyroid crisis Thyroid crisis usually occurs in the first 12 hours after thyroidectomy and causes exaggerated signs of hyperthyroidism, such as high fever, tachycardia, and extreme restlessness. Diabetic ketoacidosis is more likely to produce polyuria, polydipsia, and polyphagia; hypoglycemia, to produce weakness, tremors, profuse perspiration, and hunger. Tetany typically causes uncontrollable muscle spasms, stridor, cyanosis, and possibly asphyxia.

A patient with SIADH is treated with water restriction and administration of IV fluids. The nurses evaluates that treatment has been effective when the patient experiences a. increased urine output, decreased serum sodium, and increased urine specific gravity b. increased urine output, increased serum sodium, and decreased urine specific gravity c. decreased urine output, increased serum sodium, and decreased urine specific gravity d. decreased urine output, decreased serum sodium, and increased urine specific gravity

b. increased urine output, increased serum sodium, and decreased urine specific gravity (rationale- the patient with SIADH has water retention with hyponatremia, decreased urine output and concentrated urine with high specific gravity. improvement in the patient's condition reflected by increased urine output, normalization of serum sodium, and more water in the urine, decreasing the specific gravity.)

A patient with hypothyroidism is treated with Synthroid. When teaching the patient about the therapy, the nurse a. explains that caloric intake must be reduced when drug therapy is started b. provides written instruction for all information related to the medication therapy c. assures the patient that a return to normal function will occur with replacement therapy d. informs the patient that medications must be taken until hormone balance is reestablished

b. provides written instruction for all information related to the medication therapy (rationale- because of the mental sluggishness, inattentiveness, and memory loss that occur with hypothyroidism, it is important to provide written instructions and repeat information when teaching the patient. Caloric intake can be increased when drug therapy is started, because of an increased metabolic rate, and replacement therapy must be taken for life. Although most patients return to a normal state with treatment, cardiovascular conditions and psychoses may persist.)

Of what precautions should a client receiving radioactive iodine-131 be made aware? a.) Drink plenty of fluids, especially those high in calcium. b.) Avoid close contact with children or pregnant women for one week after administration of drug. c.) Be aware of the symptoms of tachycardia, increased metabolic rate, and anxiety. d.) Wear a mask if around children or pregnant women.

b.) Avoid close contact with children or pregnant women for one week after administration of drug. After receiving radioactive iodine-131, you should avoid prolonged, close contact with other people for several days, particularly pregnant women and small children. The majority of the radioactive iodine that has not been absorbed leaves the body during the first two days following the treatment, primarily through the urine. Small amounts will also be excreted in saliva, sweat, tears, vaginal secretions, and feces.

Which of the following nursing implications is most important in a client being medicated for Addison's disease? a. Administer oral forms of the drug with food to minimize its ulcerogenic effect. b. Monitor capillary blood glucose for hypoglycemia in the diabetic client. c. Instruct the client to never abruptly discontinue the medication. d. Teach the client to consume a diet that is high in potassium, low in sodium, and high in protein.

c. Instruct the client to never abruptly discontinue the medication. The primary medical treatment of Addison's disease is replacement of corticosteroids and mineralcorticoids, accompanied by increased sodium in the diet. The client needs to know the importance of maintaining a diet high is sodium and low in potassium. Medications should never be discontinued abruptly because crisis can ensue. Oral forms of the drug are given with food in Cushing's disease.

An incoherent female client with a history of hypothyroidism is brought to the emergency department by the rescue squad. Physical and laboratory findings reveal hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area. Knowing that these findings suggest severe hypothyroidism, nurse Libby prepares to take emergency action to prevent the potential complication of: a. Thyroid storm. b. Cretinism. c. Myxedema coma. d. Hashimoto's thyroiditis.

c. Myexedema coma. Severe hypothyroidism may result in myxedema coma, in which a drastic drop in the metabolic rate causes decreased vital signs, hypoventilation (possibly leading to respiratory acidosis), and nonpitting edema. Thyroid storm is an acute complication of hyperthyroidism. Cretinism is a form of hypothyroidism that occurs in infants. Hashimoto's thyroiditis is a common chronic inflammatory disease of the thyroid gland in which autoimmune factors play a prominent role.

A male client is admitted for treatment of the syndrome of inappropriate antidiuretic hormone (SIADH). Which nursing intervention is appropriate? a. Infusing I.V. fluids rapidly as ordered b. Encouraging increased oral intake c. Restricting fluids d. Administering glucose-containing I.V. fluids as ordered

c. Restricting fluids To reduce water retention in a client with the SIADH, the nurse should restrict fluids. Administering fluids by any route would further increase the client's already heightened fluid load.

A female client with hypothyroidism (myxedema) is receiving levothyroxine (Synthroid), 25 mcg P.O. daily. Which finding should nurse Hans recognize as an adverse drug effect? a. Dysuria b. Leg cramps c. Tachycardia d. Blurred vision

c. Tachycardia Levothyroxine, a synthetic thyroid hormone, is given to a client with hypothyroidism to simulate the effects of thyroxine. Adverse effects of this agent include tachycardia. The other options aren't associated with levothyroxine.

Which nursing diagnosis takes highest priority for a female client with hyperthyroidism? a. Risk for imbalanced nutrition: More than body requirements related to thyroid hormone excess b. Risk for impaired skin integrity related to edema, skin fragility, and poor wound healing c. Body image disturbance related to weight gain and edema d. Imbalanced nutrition: Less than body requirements related to thyroid hormone excess

d. Imbalanced nutrition: Less than body requirements related to thyroid hormone excess In the client with hyperthyroidism, excessive thyroid hormone production leads to hypermetabolism and increased nutrient metabolism. These conditions may result in a negative nitrogen balance, increased protein synthesis and breakdown, decreased glucose tolerance, and fat mobilization and depletion. This puts the client at risk for marked nutrient and calorie deficiency, making Imbalanced nutrition: Less than body requirements the most important nursing diagnosis. Options B and C may be appropriate for a client with hypothyroidism, which slows the metabolic rate.

Causes of primary hypothyroidism in adults include a. malignant or benign thyroid nodules b. surgical removal or failure of the pituitary gland c. surgical removal or radiation of thyroid gland d. autoimmune-induced atrophy of the gland

d. autoimmune-induced atrophy of the gland (rationale- both Graves disease and Hasimotos thyroiditis are autoimmune disorders that eventually destroy the thyroid gland, leading to primary hypothyroidism. Thyroid tumors most often result in hyperthyroidism. Secondary hypothyroidism occurs as a result of pituitary failure, and iatrogenic hypothyroidism results from thyroidectomy or radiation of the thyroid gland.)
