Restorative 1 Endocrine System

A nurse is reinforcing instructions with a client with diabetes mellitus who is recovering from diabetic ketoacidosis (DKA) regarding measures to prevent a recurrence. Which instruction is important for the nurse to emphasize? 1. Eat six small meals daily. 2. Test the urine ketone levels. 3. Monitor blood glucose levels frequently. 4. Receive appropriate follow-up health care.

3. Monitor blood glucose levels frequently. rationale: Client education after DKA should emphasize the need for home glucose monitoring four to five times per day. It is also important to instruct the client to notify the health care provider when illness occurs. The presence of urinary ketones indicates that DKA has already occurred. The client should eat well-balanced meals with snacks, as prescribed.

When the nurse is teaching a client who has been newly diagnosed with type 1 diabetes mellitus, which statement by the client would indicate that teaching has been effective? 1. "I will stop taking my insulin if I'm too sick to eat." 2. "I will decrease my insulin dose during times of illness." 3. "I will adjust my insulin dose according to the level of glucose in my urine." 4. "I will notify my health care provider if my blood glucose level is greater than 250 mg/dL."

4. "I will notify my health care provider if my blood glucose level is greater than 250 mg/dL." rationale: During illness, the client should monitor the blood glucose level, and he or she should notify the health care provider (HCP) if the level is greater than 250 mg/dL. Insulin should never be stopped. In fact, insulin may need to be increased during times of illness. Doses should not be adjusted without the HCP's advice.

A healthcare professional administers pramlintide (Symlin) at 0800 to a patient who has type 1 DM. At which of the following times should the patient expect the drug to exert its peak action? A) 0820 B) 0900 C) 1000 D) 1100

A) 0820

A nurse is providing instructions to a client newly diagnosed with diabetes mellitus. The nurse gives the client a list of the signs of hyperglycemia. Which of the following specific signs of this complication should be included on the list? 1. Decreased urine output 2. Profuse sweating 3. Increased thirst 4. Shakiness

3. Increased thirst rationale: The classic signs of hyperglycemia include polydipsia, polyuria, and polyphagia. Profuse sweating and shakiness would be noted in a hypoglycemic condition.

The nurse caring for a client who has had a subtotal thyroidectomy reviews the plan of care and determines which problem is the priority for this client in the immediate postoperative period? 1. Dehydration 2. Infection 3. Urinary retention 4. Bleeding

4. Bleeding rationale: Hemorrhage is one of the most severe complications that can occur following thyroidectomy. The nurse must frequently check the neck dressing for bleeding and monitor vital signs to detect early signs of hemorrhage, which could lead to shock. T3 and T4 do not regulate fluid volumes in the body. Infection is a concern for any postoperative client but is not the priority in the immediate postoperative period. Urinary retention can occur in postoperative clients as a result of medication and anesthesia but is not the priority from the options provided.

When talking to a patient who is about to begin glipizide (Glucotrol) therapy to treat type 2 diabetes mellitus, the health care professional should include which of the following instructions? A) Avoid drinking alcohol B) Sit or stand for 30 minute after taking the drug C) Urinate every 4 hour D) Take the drug 2 hour after a meal

A) Avoid drinking alcohol

When talking with a patient who is about to begin repaglindie (Prandin) therapy to treat type 2 diabetes mellitus, the health care professional should include which of the following instructions? A) Do not drink more than 1 L of grapefruit juice per day B) Carry a high-protein snack at all times C) Drink 16 oz of water after taking the drug D) Use ginseng to reduce nausea

A) Do not drink more than 1 L of grapefruit juice per day

A 67-year-old male client has been complaining of sleeping more, increased urination, anorexia, weakness, irritability, depression, and bone pain that interferes with her going outdoors. Based on these assessment findings, nurse Richard would suspect which of the following disorders? a. Diabetes mellitus b. Diabetes insipidus c. Hypoparathyroidism d. Hyperparathyroidism

ANSWER:D Hyperparathyroidism is most common in older women and is characterized by bone pain and weakness from excess parathyroid hormone (PTH). Clients also exhibit hypercaliuria-causing polyuria. While clients with diabetes mellitus and diabetes insipidus also have polyuria, they don't have bone pain and increased sleeping. Hypoparathyroidism is characterized by urinary frequency rather than polyuria.

A patient who is taking metformin (Glucophage) to treat type 2 DM plans to undergo angiography using iodine-containing contrast dye. The health care professional should recognize that an interaction between metformin and the IV contrast dye can increase the patient's risk for which of the following? A) Hypokalemia B) Hyperglycemia C) Acute renal failure D) Acute pancreatitis

C) Acute renal failure

A 19-year-old previously healthy woman has had a mild pharyngitis followed by a high fever over the past 24 hours. When seen in the emergency room, her skin now shows extensive areas of purpura. Vital signs include T 39.5 C, P 102/minute, RR 21/minute, and BP 80/55 mm Hg. Laboratory studies show a serum sodium of 115 mmol/L, potassium 5.3 mmol/L, chloride 92 mmol/L, CO2 22 mmol/L, glucose 42 mg/dL, and creatinine 1.1 mg/dL. Which of the following is the most likely diagnosis? A Idiopathic adrenalitis B Disseminated tuberculosis C Acute Rheumatic fever D Sheehan syndrome E Meningococcemia F UTI G Acute lukemia

Answer is E This is acute adrenal insufficiency marked by hyponatremia, hyperkalemia, and hypoglycemia. Infection with Neisseria meningitidis can produce the Waterhouse-Friderischsen syndrome

A nurse is providing teaching to a client who has type 2 diabetes mellitus and is starting repaglinide (Prandin). Which of the following statements made by the client indicates understanding of the administration of this medication? A) "I'll take this medicine with my meals" B) "I'll take this medicine 30 minutes before I eat" C) "I'll take this medicine just before I go to bed" D) "I'll take this medicine as soon as I wake up in the morning"

B) "I'll take this medicine 30 minutes before I eat" Repaglinide causes a rapid short-lived release of insulin. The client should take this medication within 30 min before each meal so that insulin is available when food is digested

A healthcare professional is caring for a patient who is abotu to begin taking pioglitazone (Actos) to treat type 2 diabetes mellitus. The health care professional should explain to the patient the need to monitor which of the following laboratory tests? (Select all that apply) A) Thyroid-stimulating hormone (TSH) B) Alanine aminotransferase (ALT) C) LDL D) CBC E) Creatinine clearance

B) Alanine aminotransferase (ALT) C) LDL

D) Inject the insulin subcutaneously

A 40-year-old gentleman presents with episodic headaches and palpitations. Attributing it to his tendency to worry excessively, he put it off for several months until he began to sweat episodically too. In the clinic, his blood pressure is found to be elevated at 160/120 mmHg. Plasma metanephrines are elevated and an abdominal CT scan reveals an adrenal mass.What is the diagnosis?

A nurse is reviewing discharge teaching with a client who has Cushing's syndrome. Which statement by the client indicates that the instructions related to dietary management were understood? 1. "I can eat foods that contain potassium." 2. "I will need to limit the amount of protein in my diet." 3. "I am fortunate that I can eat all the salty foods I enjoy." 4. "I am fortunate that I do not need to follow any special diet."

1. "I can eat foods that contain potassium." rationale: A diet that is low in calories, carbohydrates, and sodium but ample in protein and potassium content is encouraged for a client with Cushing's syndrome. Such a diet promotes weight loss, the reduction of edema and hypertension, the control of hypokalemia, and the rebuilding of wasted tissue.

A nurse is collecting data from a client newly diagnosed with diabetes mellitus regarding the client's learning readiness. Which client behavior indicates to the nurse that the client is not ready to learn? 1. The client complains of fatigue whenever the nurse plans a teaching session. 2. The client asks if the spouse can attend the classes also. 3. The client asks for written materials about diabetes before class. 4. The client asks appropriate questions about what will be taught.

1. The client complains of fatigue whenever the nurse plans a teaching session. rationale: Physical symptoms can interfere with an individual's ability to learn and can indicate to the teacher that the learner lacks motivation to learn if the symptoms repeatedly recur when teaching is initiated. Options 2, 3, and 4 identify the client as actively seeking information.

diet requirements for Addison's patient

high salt, carbs, and protein with low potassium

A nurse is assigned to care for a client at home who has a diagnosis of type 1 diabetes mellitus. When the nurse arrives to care for the client, the client tells the nurse that she has been vomiting and has diarrhea. Which additional statement by the client indicates a need for further teaching? 1. "I need to stop my insulin." 2. "I need to increase my fluid intake." 3. "I need to call my health care provider." 4. "I need to monitor my blood glucose every 4 to 6 hours."

1. "I need to stop my insulin." rationale: When a client with diabetes is unable to eat normally because of illness, the client should still take the prescribed insulin or oral medication. Additional fluids should be consumed and a call placed to the health care provider. The client should monitor the blood glucose levels every 4 to 6 hours.

A nurse is assigned to assist in caring for a client admitted to the emergency department with diabetic ketoacidosis (DKA). In the acute phase, the priority nursing action is to plan to prepare to: 1. Administer intravenous (IV) regular insulin. 2. Administer IV 5% dextrose. 3. Correct the acidosis. 4. Apply an electrocardiogram (ECG) monitor.

1. Administer intravenous (IV) regular insulin. rationale: Lack (absolute or relative) of insulin is the primary cause leading to DKA. Treatment consists of IV fluids (normal saline initially), regular insulin administration, and potassium replacement, followed by correcting the acidosis. An ECG monitor may be applied but is not the priority in this situation.

pheochromocytoma is a

tumor of the adrenal glands

A nurse is collecting data on a client admitted to the hospital with a diagnosis of myxedema. Which data collection technique will provide data necessary to support the admitting diagnosis? 1. Auscultation of lung sounds 2. Inspection of facial features 3. Percussion of the thyroid gland 4. Palpation of the adrenal glands

rationale: Inspection of facial features will reveal the characteristic coarse features, presence of edema around the eyes and face, and a blank expression that are characteristic of myxedema. The techniques in the remaining options will not reveal any data that would support the diagnosis of myxedema.

To determine the effectiveness of desmopressin (DDAVP), a health care professional should monitor a patient's? A) Peripheral pulses B) Urine output C) Skin integrity D) Blood glucose

B) Urine output

expected finding for patient with diabetes insipidus

increased Hct level

A patient who is taking glipizide (Glucotrol) to treat type 2 DM contacts the healthcare professional to report feeling shaky, hungry, and fatigued. The healthcare professional should tell the patient to do which of the following? A) Drink 16 oz of water B) Perform a fingerstick blood glucose check C) Take another glipizide tablet D) Lie down and rest

B) Perform a fingerstick blood glucose check

You are caring for a patient who is taking levothyroxine (Synthroid) to treat hypothyroidism. The patient reports palpitations, weight loss, and diarrhea. You suspect which of the following adverse effects of this drug? A) Hyperthyroidism B) Addison's disease C) Myexedma D) Hyperglycemia

A) Hyperthyroidism

A health care provider has prescribed propylthiouracil (PTU) for a client with hyperthyroidism, and the nurse assists in developing a plan of care for the client. A priority nursing measure to be included in the plan regarding this medication is to monitor the client for: 1. Signs and symptoms of hypothyroidism 2. Signs and symptoms of hyperglycemia 3. Relief of pain 4. Signs of renal toxicity

1. Signs and symptoms of hypothyroidism rationale: Excessive dosing with propylthiouracil 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.

A nurse is caring for a client with pheochromocytoma. The client is scheduled for an adrenalectomy. During the preoperative period, the priority nursing action would be to monitor the: 1. Vital signs 2. Intake and output 3. Blood urea nitrogen (BUN) level 4. Urine for glucose and acetone

1. Vital signs rationale: Hypertension is the hallmark of pheochromocytoma. Severe hypertension can precipitate a brain attack (stroke) or sudden blindness. Although all of the options are accurate nursing interventions for the client with pheochromocytoma, the priority nursing action is to monitor the vital signs, particularly the blood pressure.

A nurse has reinforced instructions about measuring blood glucose levels to a client newly diagnosed with diabetes mellitus. The nurse determines that the client understands the procedure when making which most accurate statement? 1. "I should check my blood glucose level before eating a big meal." 2. "I should check my blood glucose level before eating each meal, regardless of how much I eat." 3. "I should check my blood glucose level 2 hours after each meal." 4. "I should check my blood glucose level once a day."

2. "I should check my blood glucose level before eating each meal, regardless of how much I eat." rationale: The most effective and accurate measure for testing blood glucose is to test the level before each meal regardless of the amount of food to be eaten. The client should also check the blood glucose level at bedtime. Checking the level after the meal will provide an inaccurate assessment of diabetic control. Checking the level once daily will not provide enough data related to controlling the diabetes mellitus.

A comatose client with an admitting diagnosis of diabetic ketoacidosis (DKA) has a blood glucose of 368 mg/dL, arterial pH of 7.2, arterial bicarbonate of 14 mEq/L, and a positive for serum ketones. The diagnosis is supported by which noted data? 1. Hypertension 2. Fruity breath odor 3. Slow regular breathing 4. Moist mucous membranes

2. Fruity breath odor rationale: Diabetic ketoacidotic coma is usually identified with a fruity breath odor, dry cracked mucous membranes, hypotension, and rapid deep breathing.

A nurse in an outpatient diabetes clinic is assisting in caring for a client on insulin pump therapy. Which statement by the client indicates that a knowledge deficit exists regarding insulin pump therapy? 1. "If my blood sugars are elevated, I can bolus myself with additional insulin as prescribed." 2. "I'll need to check my blood sugars before meals in case I need a pre-meal insulin bolus." 3. "Now that I have this pump, I don't have to worry about insulin reactions or ketoacidosis occurring again." 4. "I still need to follow an appropriate diet and exercise plan even though I don't have to inject myself daily anymore."

3. "Now that I have this pump, I don't have to worry about insulin reactions or ketoacidosis occurring again." rationale: All of the statements are correct in regard to insulin pump therapy, except the one that mentions insulin reactions and ketoacidosis. Hypoglycemic reactions can occur if there is an error in calculating the insulin dose or if the pump malfunctions. Ketoacidosis can occur if too little insulin is used or if there is an increase in metabolic need. The pump does not have a built-in blood glucose monitoring feedback system, so the client is subject to the usual complications associated with insulin administration without the use of a pump.

A nurse is preparing to administer an injection of regular insulin. The vial of the regular insulin has been refrigerated. On inspection of the vial, the nurse finds that the medication is frozen. The nurse should: 1. Wait for the insulin to thaw at room temperature. 2. Check the temperature settings of the refrigerator. 3. Discard the insulin and obtain another vial. 4. Rotate the vial between the hands until the medication becomes liquid.

3. Discard the insulin and obtain another vial. rationale: Insulin preparations are stable at room temperature for up to 1 month without significant loss of activity. Insulin should not be frozen. If the insulin is frozen, it should be discarded and the nurse should obtain another vial. Options 1, 2, and 4 are incorrect.

A client with type 2 diabetes mellitus has a blood glucose of more than 600 mg/dL and is complaining of polydipsia, polyuria, weight loss, and weakness. The nurse reviews the health care provider's documentation and would expect to note which of the following diagnoses? 1. Diabetic ketoacidosis (DKA) 2. Hypoglycemia 3. Hyperglycemic hyperosmolar nonketotic syndrome (HHNS) 4. Pheochromocytoma

3. Hyperglycemic hyperosmolar nonketotic syndrome (HHNS) rationale: HHNS is seen primarily in individuals with type 2 diabetes who experience a relative deficiency of insulin. The onset of symptoms may be gradual. The symptoms may include polyuria, polydipsia, dehydration, mental status alterations, weight loss, and weakness. DKA normally occurs in type 1 diabetes mellitus. The clinical manifestations noted in the question are not signs of hypoglycemia. Pheochromocytoma is not related to these clinical manifestations.

A client with newly diagnosed Cushing's syndrome expresses concern about personal appearance, specifically about the "buffalo hump" that has developed at the base of the neck. When counseling the client about this manifestation, the nurse should incorporate the knowledge that: 1. This is a permanent feature. 2. It can be minimized by wearing tight clothing. 3. It may slowly improve with treatment of the disorder. 4. It will quickly disappear once medication therapy is started.

3. It may slowly improve with treatment of the disorder. rationale: The client with Cushing's syndrome should be reassured that most physical changes resolve over time with treatment. The other options are incorrect.

A nurse enters the room of a client with type 1 diabetes mellitus and finds the client difficult to arouse. The client's skin is warm and flushed, and the pulse and respiratory rate are elevated from the client's baseline. The nurse would immediately: 1. Prepare for the administration of an insulin drip. 2. Give the client a glass of orange juice. 3. Prepare for the administration of a bolus dose of 50% dextrose. 4. Check the client's capillary blood glucose.

4. Check the client's capillary blood glucose. rationale: The nurse must first obtain a blood glucose reading to determine the client's problem. Options 2 and 3 would be implemented as needed in the treatment of hypoglycemia. Insulin therapy is guided by blood glucose measurement.

A client with Graves' disease has exophthalmos and is experiencing photophobia. Which intervention would best assist the client with this problem? 1. Administering methimazole (Tapazole) every 8 hours 2. Lubricating the eyes with tap water every 2 to 4 hours 3. Instructing the client to avoid straining or heavy lifting 4. Obtaining dark glasses for the client

4. Obtaining dark glasses for the client rationale: Because photophobia (light intolerance) accompanies this disorder, dark glasses are helpful in alleviating the symptom. Medical therapy for Graves' disease does not help alleviate the clinical manifestation of exophthalmos. Other interventions may be used to relieve the drying that occurs from not being able to completely close the eyes; however, the question is asking what the nurse can do for photophobia. Tap water, which is hypotonic, could actually cause more swelling to the eye because it could pull fluid into the interstitial space. In addition, the client is at risk for developing an eye infection because the solution is not sterile. There is no need to prevent straining with exophthalmos.

A nurse has collected data on a client with diabetes mellitus. Findings include a fasting blood glucose of 130 mg/dL, temperature 101° F, pulse of 88 beats per minute, respirations of 22 breaths per minute, and a blood pressure of 118/78 mm Hg. Which finding would be of concern to the nurse? 1. Pulse and respirations 2. Blood pressure 3. Blood glucose 4. Temperature

4. Temperature rationale: Elevated temperature may be indicative of infection, which is a leading cause of hyperglycemic hyperosmolar nonketotic syndrome (HHNS) or diabetic ketoacidosis (DKA). Options 1, 2, and 3 are findings that are within a normal range.

When talking with a 30-year old woman who will receive radioactive iodine-131 (Iodotope) to treat Graves' disease, you should include which of the following instructions? (Select all that apply) A) Report weight gain and edema B) Use effective contraception C) Allow 2-3 months for full effects D) Expect periodic blood sampling E) Obtain regular eye examinations

A, B, C, D

You should instruct the patient to do which of the following to help reduce her risk for adverse effects of this drug? (Select all that apply) A) Expect lifelong therapy B) Carry extra doses of the drug C) Expect periodic blood sampling D) Urinate every 4 hours E) Report increased stress

A, B, C, E

A health care professional is caring for a patient who is about to begin taking propylthiouracil (PTU) to treat hyperthyroidism. The health care professional should tell the patient to report which of the following adverse effects? (Select all that apply) A) Sore throat B) Muscle pain C) Insomnia D) Bradycardia E) Rash

A, B, D, E

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).

ANSWER: A ADH is the hormone clients with diabetes insipidus lack. The client's TSH, FSH, and LH levels won't be affected.

Which of the following symptoms is not typical of Cushing's syndrome? Answers: A. Osteoporosis B. Weight loss C. Diabetes D. Mood instability

ANSWER: B Cushing's syndrome tends to produce rapid weight gain, not weight loss.

What is a hormone secreted from the posterior lobe of the pituitary gland? Answers: A. LH B. MSH C. ADH D. GnRH

ANSWER: C ADH is secreted from the posterior pituitary. LH comes from the anterior pituitary, MSH from the intermediate. GnRH is released from the hypothalamus.

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.

ANSWER:A 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.

When talking with a patient who is about to begin exenatide (Byetta) therapy to treat type 2 DM, the healthcare professional should include which of the following instructions? (Select all that apply) A) Inject the drug subcutaneously B) Expect the peak effect in 2 hour C) Use the drug as a supplement to an oral hypoglycemic D) Inject the drug 1 hour after a meal E) Discard used pens 10 days after the first use

B) Expect the peak effect in 2 hour C) Use the drug as a supplement to an oral hypoglycemic

A 50-year-old female is evaluated by her physician for recent weight gain. Physical examination is notable for truncal obesity, wasting of her distal musculature and moon facies. In addition she complains of abnormal stretch marks that surround her abdomen. The physician suspects pituitary adenoma. Which of the following high-dose dexamethasone suppression test findings and baseline ACTH findings would support his view? 1. Cortisol suppression, normal baseline ACTH 2. Cortisol suppression, high baseline ACTH 3. No cortisol suppression, high baseline ACTH 4. No cortisol suppression, low baseline ACTH 5. Elevation of cortisol above pre-test levels, high baseline ACTH

Answer is 2 The most common cause of Cushing's syndrome is the administration of exogenous steroids (iatrogenic Cushing's). Several endogenous processes can also produce Cushing's syndrome, including pituitary adenoma (Cushing's disease, 70% of endogenous cases), adrenal adenoma (15% of case), and ectopic ACTH production (15% of cases). To distinguish between a pituitary adenoma that produces ACTH and an ectopic carcinoma producing ACTH, a dexamethasone suppression test is completed.

A 46-year-old female with a history of type I diabetes mellitus presents with complaints of chronic fatigue, muscle weakness, and headaches. These symptoms have been present for the past year. Her vital signs today are as follows: T 36.9 C, HR 82 bpm, BP 88/52 mmHg, RR 14 rpm, O2 sat98% on room air. Physical exam does not demonstrate any specific abnormalities. After inquiry, the patient reports that her blood pressure has always "run low." Initial work-up reveals an 8AM cortisol level of 3.6 ug/dL. Which of the following is the best next step in management of this patient? 1. Low dose dexamethasone suppression test 2. High dose dexamethasone suppression test 3. Urgent 5mg hydrocortisone injection 4. Cosyntropin stimulation test 5. Pituitary MRI

Answer is 4 A cosyntropin stimulation test involves measuring baseline serum cortisol levels prior to the injection of cosyntropin (synthetic ACTH). Serum cortisol is then measured again one hour after the injection. A sufficient increase in serum cortisol after administration of cosyntropin rules out primary adrenal insufficiency and necessitates further work-up for other etiologies. An insufficient or absent rise in serum cortisol in response to the injection (typically, a serum cortisol level less than 18 ug/dL) is suggestive of primary adrenal insufficiency (Addison's disease). Primary adrenal insufficiency is often associated with a constellation of other autoimmune diseases such as autoimmune thyroid disease or type I diabetes mellitus.

A 10-week-old female infant born at home presents to the pediatrician because her mother is worried that "she sleeps too much, always feels cold, and does not have bowel movements very frequently." On physical exam, the child has hypotonia, slight to mild jaundice, and the following features (Figure A & B). Which of the following lab findings would be seen in this patient? 1. Decreased total & free T4, increased TSH 2. Increased total & free T4, decreased TSH 3. Inhibitory anti-TSH receptor antibodies 4. Stimulatory anti-TSH receptor antibodies 5. Decreased total T4 & T3, normal TSH, increased reverse T3

Answer: 1 CH results from a lack of maternal iodine intake during pregnancy, or from a defect in T4 synthesis or thyroid formation. Severe mental retardation can result if this condition is not treated, as T4 is very crucial for normal brain development during the first two years of life. In addition, untreated CH increases the risk of mitral regurgitation. Infants affected by CH typically present with severe mental retardation, increased weight, short stature, coarse facial features, macroglossia, umbilical hernia, myxedema, hypotonia, mild jaundice, constipation, or poor feeding. Lab results will reveal a decreased total and free T4 and elevated TSH serum levels. Treatment usually consists of levothyroxine replacement.

A patient is about to start taking sustained release glipizide (Glucotrol) to treat type 2 diabetes mellitus. Which of the following instructions should you include when talking with the patient about taking this drug? A) Chew the tablet completely before swallowing it B) Take it once a day, 30 minutes before selected meals C) Take it in the evening before bedtime D) Drink 16 oz of water right after taking

B) Take it once a day, 30 minutes before selected meals

You are caring for a patient who takes acarbose (Precose) and a sulfonylurea to treat type 2 DM. Which of the following is an indication of an adverse reaction to this drug combination? A) Polyuria B) Tremors C) Bradycardia D) Thirst

B) Tremors

A nurse is teaching clients in an outpatient facility about the use of insulin to treat type 1 diabetes mellitus. For which of the following types of insulin should the nurse tell the clients to expect a peak effect 1-5 hr after administration? A) Insulin glargine (Lantus) B) NPH insulin (Humulin N) C) Regular Insulin (Humulin R) D) Insulin Lispro (Humalog)

C ) Regular insulin (Humulin R)Regular insulin has a peak effect around 1-5 hr following administration

A 39-year-old man presents to the emergency room with fever and cough. He has no prior smoking history. He is originally from Russia and since immigrating 5 years ago, he has contracted HIV. On the second day of admission, he develops severe hypotension, abdominal pain and acute renal failure. A CT of the abdomen and pelvis reveals extensive calcification of the adrenal glands bilaterally. What is the most likely diagnosis? 1. Primary adrenal insufficiency secondary to autoimmunity 2. Primary adrenal insufficiency secondary to metastatic lung cancer 3. Primary adrenal insufficiency secondary to M. tuberculosis 4. Secondary adrenal insufficiency 5. Tertiary adrenal insufficnecy

Correct answer is 3 The most common cause of Addison's disease (primary adrenal insufficiency) worldwide is tuberculosis, while autoimmune disease is the most common cause in the Western world. However, the most common cause of adrenal insufficiency overall is rapid discontinuation of chronic corticosteroids. Patients with extrapulmonary tuberculosis like this one are unable to contain the bacteria in the primary or secondary stage and experience dissemination throughout the body. Extrapulmonary tuberculosis is more often found in patients with HIV. Sites of extrapulmonary tuberculosis include the lymph nodes, pleura, genitourinary tract, spine (Pott's disease), intestine, meninges, eye, and adrenal glands.

A health care professional is talking to a patient about self-injecting Regular insulin (Humulin). The health care professional should tell the patient to rotate injection sites to prevent which of the following? A) Rapid absorption B) Intradermal injection C) Injection pain D) Lipohypertrophy

D) Lipohypertrophy

Which statement by the client would cause the nurse to suspect that the thyroid test results drawn on the client this morning may be inaccurate? 1. "I had a radionuclide test done 3 days ago." 2. "When I exercise I sweat more than normal." 3. "I drank some water before the blood was drawn." 4. "That hamburger I ate before the test sure tasted good."

1. "I had a radionuclide test done 3 days ago." rationale: Option 1 indicates that a recent radionuclide scan had been performed. Recent radionuclide scans performed before the test can affect thyroid laboratory results. No food, fluid, or activity restrictions are required for this test, so options 2, 3, and 4 are incorrect.

After several diagnostic tests, a client is diagnosed with diabetes insipidus. The nurse understands that which symptom is indicative of this disorder? 1. Diarrhea 2. Polydipsia 3. Weight gain 4. Blurred vision

2. Polydipsia rationale: Polydipsia and polyuria are classic symptoms of diabetes insipidus. The urine is pale in color, and its specific gravity is low. Anorexia and weight loss occur. Diarrhea, weight loss, and blurred vision are not manifestations of the disorder.

A client with a diagnosis of diabetic ketoacidosis (DKA) is being treated in the emergency department. Which of the following findings would the nurse expect to note as confirming this diagnosis? 1. Elevated blood glucose and low plasma bicarbonate 2. Decreased urine output 3. Increased respirations and an increase in pH 4. Coma

1. Elevated blood glucose and low plasma bicarbonate rationale: In DKA, the arterial pH is less than 7.35, plasma bicarbonate is less than 15 mEq/L, the blood glucose level is higher than 250 mg/dL, and ketones are present in the blood and urine. The client would be experiencing polyuria and Kussmaul's respirations. Coma may occur if DKA is not treated, but coma would not confirm the diagnosis.

A nurse is reviewing a plan of care for a client with Addison's disease. The nurse notes that the client is at risk for dehydration and suggests nursing interventions that will prevent this occurrence. Which nursing intervention is an appropriate component of the plan of care? Select all that apply. 1. Encouraging fluid intake of at least 3000 mL/day 2. Encouraging an intake of low-protein foods 3. Monitoring for changes in mental status 4. Monitoring intake and output 5. Maintaining a low-sodium diet

1. Encouraging fluid intake of at least 3000 mL/day 3. Monitoring for changes in mental status 4. Monitoring intake and output rationale: The client at risk for deficient fluid volume should be encouraged to eat regular meals and snacks and to increase the intake of sodium, protein, and complex carbohydrates. Oral replacement of sodium losses is necessary, and maintenance of adequate blood glucose levels is required.

A client with Addison's disease asks the nurse how a newly prescribed medication, fludrocortisone acetate (Florinef), will improve the condition. When formulating a response, the nurse should incorporate that a key action of this medication is to: 1. Help restore electrolyte balance. 2. Make the body produce more cortisol. 3. Replace insufficient circulating estrogens. 4. Alter the body's immune system functioning.

1. Help restore electrolyte balance. rationale: Fludrocortisone acetate is a long-acting oral medication with mineralocorticoid and moderate glucocorticoid activity. It is prescribed for the long-term management of Addison's disease. Mineralocorticoids cause renal reabsorption of sodium and chloride ions and the excretion of potassium and hydrogen ions. These actions help restore electrolyte balance in the body. The other options are incorrect.

A client is admitted to the hospital with a diagnosis of diabetic ketoacidosis (DKA). The initial serum glucose level was 950 mg/dL. Intravenous (IV) insulin was started along with rehydration with IV normal saline. The serum glucose level is now 240 mg/dL. The nurse who is assisting in caring for the client obtains which of the following items, anticipating a health care provider's prescription? 1. IV infusion containing 5% dextrose 2. NPH insulin and a syringe for subcutaneous injection 3. An ampule of 50% dextrose 4. Phenytoin (Dilantin) for prevention of seizures

1. IV infusion containing 5% dextrose rationale: During management of DKA, when the blood glucose level falls to 300 mg/dL, the infusion rate is reduced and 5% dextrose is added to maintain a blood glucose level of about 250 mg/dL, or until the client recovers from ketosis. NPH insulin is not used to treat DKA; 50% dextrose is used to treat hypoglycemia. Phenytoin is not a normal treatment measure in DKA.

A nurse notes in the medical record that a client with Cushing's syndrome is experiencing fluid overload. Which interventions should be included in the plan of care? Select all that apply. 1. Monitoring daily weight 2. Monitoring intake and output 3. Maintaining a low-potassium diet 4. Monitoring extremities for edema 5. Maintaining a low-sodium diet

1. Monitoring daily weight 2. Monitoring intake and output 4. Monitoring extremities for edema 5. Maintaining a low-sodium diet rationale: The client with Cushing's syndrome experiencing fluid overload should be maintained on a high-potassium and low-sodium diet. Decreased sodium intake decreases renal retention of sodium and water. Monitoring weight, intake, output, and extremities for edema are all appropriate interventions for such a nursing diagnosis.

When a nurse notes that a client with type 1 diabetes mellitus has lipodystrophy on both upper thighs, what information should the nurse obtain from the client? 1. Plan of injection rotation 2. Consistency of aspiration 3. Preparation of the injection site 4. Angle at which the medication is administered

1. Plan of injection rotation rationale: Lipodystrophy (i.e., the hypertrophy of subcutaneous tissue at the injection site) occurs in some diabetic clients when the same injection sites are used for prolonged periods of time. Thus, clients are instructed to adhere to a rotating injection site plan to avoid tissue changes. Preparation of the site, aspiration, and the angle of insulin administration do not produce tissue damage.

A nurse is monitoring a client who has been newly diagnosed with diabetes mellitus for signs of complications. Which of the following, if exhibited by the client, would indicate hyperglycemia and thus warrant health care provider notification? 1. Polyuria 2. Bradycardia 3. Diaphoresis 4. Hypertension

1. Polyuria rationale: The classic symptoms of hyperglycemia include polydipsia, polyuria, and polyphagia. Options 2, 3, and 4 are not signs of hyperglycemia.

A nurse is caring for a client with a diagnosis of hypoparathyroidism. The nurse reviews the laboratory results drawn on the client and notes that the calcium level is extremely low. The nurse would expect to note which of the following on data collection of the client? 1. Positive Trousseau's sign 2. Negative Chvostek's sign 3. Unresponsive pupils 4. Hyperactive bowel sounds

1. Positive Trousseau's sign rationale: Hypoparathyroidism is related to a lack of parathyroid hormone secretion or to a decreased effectiveness of parathyroid hormone on target tissues. The end result of this disorder is hypocalcemia. When serum calcium levels are critically low, the client may exhibit positive Chvostek's and Trousseau's signs, which indicate potential tetany. Options 2, 3, and 4 are not related to the presence of hypocalcemia.

A client with diabetes mellitus visits the health care clinic. The client previously had been well controlled with glyburide (Diabeta), but recently, the fasting blood glucose has been running 180 to 200 mg/dL. Which of the following medications, if added to the client's regimen, may be contributing to the hyperglycemia? 1. Prednisone 2. Atenolol (Tenormin) 3. Phenelzine (Nardil) 4. Allopurinol (Zyloprim)

1. Prednisone rationale: Prednisone may decrease the effect of oral hypoglycemics, insulin, diuretics, and potassium supplements. Options 2, a β-blocker, and 3, a monoamine oxidase inhibitor, have their own intrinsic hypoglycemic activity. Option 4 decreases urinary excretion of sulfonylurea agents, causing increased levels of the oral medications, which can lead to hypoglycemia.

A client with diabetes mellitus is being discharged following treatment for hyperglycemic hyperosmolar nonketotic syndrome (HHNS) precipitated by acute illness. The client states to the nurse, "I will call the doctor next time I can't eat for more than a day or so." The nurse plans care, understanding that which of the following accurately reflects this client's level of knowledge? 1. The client needs immediate education before discharge. 2. The client's statement is accurate, but knowledge should be evaluated further. 3. The client's statement is inaccurate, and the client should be scheduled for outpatient diabetic counseling. 4. The client requires follow-up teaching regarding the administration of insulin.

1. The client needs immediate education before discharge. rationale: If the client becomes ill and cannot retain fluids or food for a period of 4 hours, the health care provider should be notified. The client's statement in this question indicates a need for immediate education to prevent HHNS, a life-threatening emergency situation.

A nursing instructor asks a student to describe the pathophysiology that occurs in Cushing's disease. Which statement by the student indicates an accurate understanding of this disorder? 1. "Cushing's disease is characterized by an oversecretion of insulin." 2. "Cushing's disease is characterized by an oversecretion of glucocorticoid hormones." 3. "Cushing's disease is characterized by an undersecretion of corticotropic hormones." 4. "Cushing's disease is characterized by an undersecretion of glucocorticoid hormones."

2. "Cushing's disease is characterized by an oversecretion of glucocorticoid hormones." rationale: Cushing's syndrome is characterized by an oversecretion of glucocorticoid hormones. Addison's disease is characterized by the failure of the adrenal cortex to produce and secrete adrenocortical hormones. Options 1 and 4 are inaccurate regarding Cushing's syndrome.

A client with type 1 diabetes mellitus takes NPH insulin every morning and checks the blood glucose level four times per day. The client tells the nurse that yesterday the late afternoon blood glucose was 60 mg/dL and that she "felt funny." Which statement by the client would indicate an understanding of this occurrence? 1. "My blood glucose levels are running low because I'm tired." 2. "I forgot to take my usual afternoon snack yesterday." 3. "I took less insulin this morning so I won't feel funny today." 4. "I don't know why I have to check my blood glucose four times a day. That seems too much."

2. "I forgot to take my usual afternoon snack yesterday." rationale: Hypoglycemia is a blood glucose level of 60 mg/dL or less. The causes are multiple, but, in this case, omitting the afternoon snack is the cause. Fatigue and self-adjustment of dose are incorrect options. Recommended blood glucose testing for the client with type 1 diabetes mellitus is at least four times a day.

A nurse is reinforcing home care instructions to a client with a diagnosis of Cushing's syndrome. Which statement reflects a need for further client education? 1. "Taking my medications exactly as prescribed is essential." 2. "I need to read the labels on any over-the-counter medications I purchase." 3. "My family needs to be familiar with the signs and symptoms of hypoadrenalism." 4. "I could experience the signs and symptoms of hyperadrenalism because of Cushing's."

2. "I need to read the labels on any over-the-counter medications I purchase." rationale: The client with Cushing's syndrome should be instructed to take the medications exactly as prescribed. The nurse should emphasize the importance of continuing medications, consulting with the health care provider before purchasing any over-the-counter medications, and maintaining regular follow-up care. The nurse should also instruct the client in the signs and symptoms of both

A nurse is caring for a client with Addison's disease. The nurse checks the vital signs and determines that the client has orthostatic hypotension. The nurse determines that this finding relates to which of the following? 1. A decrease in cortisol release 2. A decreased secretion of aldosterone 3. An increase in epinephrine secretion 4. Increased levels of androgens

2. A decreased secretion of aldosterone rationale: A decreased secretion of aldosterone results in a limited reabsorption of sodium and water; therefore the client experiences fluid volume deficit. A decrease in cortisol, an increase in epinephrine, and an increase in androgen secretion do not result in orthostatic hypotension.

A client is admitted with a diagnosis of pheochromocytoma. The nurse would monitor which of the following to detect the most common sign of pheochromocytoma? 1. Skin temperature 2. Blood pressure 3. Urine ketones 4. Weight

2. Blood pressure rationale: Hypertension is the major symptom associated with pheochromocytoma and is monitored by taking the client's blood pressure. Glycosuria, weight loss, and diaphoresis are other clinical manifestations of pheochromocytoma; however, hypertension is the most common sign.

When caring for a client diagnosed with pheochromocytoma, what information should the nurse know when assisting with planning care? 1. Profound hypotension may occur. 2. Excessive catecholamines are released. 3. The condition is not curable and is treated symptomatically. 4. Hypoglycemia is the primary presenting symptom.

2. Excessive catecholamines are released. rationale: Pheochromocytoma is a catecholamine-producing tumor of the adrenal gland and causes secretion of excessive amounts of epinephrine and norepinephrine. Hypertension is the principal manifestation, and the client has episodes of a high blood pressure accompanied by pounding headaches. The excessive release of catecholamine also results in excessive conversion of glycogen into glucose in the liver. Consequently, hyperglycemia and glucosuria occur during attacks. Pheochromocytoma is curable. The primary treatment is surgical removal of one or both of the adrenal glands, depending on whether the tumor is unilateral or bilateral.

A nurse is caring for a client with pheochromocytoma. The client asks for a snack and something warm to drink. The appropriate choice for this client to meet nutritional needs would be which of the following? 1. Crackers with cheese and tea 2. Graham crackers and warm milk 3. Toast with peanut butter and cocoa 4. Vanilla wafers and coffee with cream and sugar

2. Graham crackers and warm milk rationale: The client with pheochromocytoma needs to be provided with a diet that is high in vitamins, minerals, and calories. Of particular importance is that food or beverages that contain caffeine (e.g., chocolate, coffee, tea, and cola) are prohibited.

A nurse is caring for a client after thyroidectomy and monitoring for signs of thyroid storm. The nurse understands that which of the following is a manifestation associated with this disorder? 1. Bradycardia 2. Hypotension 3. Constipation 4. Hypothermia

2. Hypotension rationale: Clinical manifestations associated with thyroid storm include a fever as high as 106° F (41.1° C), severe tachycardia, profuse diarrhea, extreme vasodilation, hypotension, atrial fibrillation, hyperreflexia, abdominal pain, diarrhea, and dehydration. With this disorder, the client's condition can rapidly progress to coma and cardiovascular collapse.

A client with Cushing's disease is being admitted to the hospital after a stab wound to the abdomen. The nurse plans care and places highest priority on which potential problem? 1. Nervousness 2. Infection 3. Concern about appearance 4. Inability to care for self

2. Infection rationale: The client with a stab wound has a break in the body's first line of defense against infection. The client with Cushing's disease is at great risk for infection because of excess cortisol secretion and subsequent impaired antibody function and decreased proliferation of lymphocytes. The client may also have a potential for the problems listed in the other options but these are not the highest priority at this time.

A nurse is caring for a postoperative parathyroidectomy client. Which of the following would require the nurse's immediate attention? 1. Incisional pain 2. Laryngeal stridor 3. Difficulty voiding 4. Abdominal cramps

2. Laryngeal stridor rationale: During the postoperative period, the nurse carefully observes the client for signs of hemorrhage, which cause swelling and the compression of adjacent tissue. Laryngeal stridor is a harsh, high-pitched sound heard on inspiration and expiration that is caused by the compression of the trachea and that leads to respiratory distress. It is an acute emergency situation that requires immediate attention to avoid the complete obstruction of the airway.

What would the nurse anticipate being included in the plan of care for a client who has been diagnosed with Graves' disease? 1. Provide a high-fiber diet. 2. Provide a restful environment. 3. Provide three small meals per day. 4. Provide the client with extra blankets.

2. Provide a restful environment. rationale: Because of the hypermetabolic state, the client with Graves' disease needs to be provided with an environment that is restful both physically and mentally. Six full meals a day that are well balanced and high in calories are required, because of the accelerated metabolic rate. Foods that increase peristalsis (e.g., high-fiber foods) need to be avoided. These clients suffer from heat intolerance and require a cool environment.

A nurse reinforces teaching with a client with diabetes mellitus regarding differentiating between hypoglycemia and ketoacidosis. The client demonstrates an understanding of the teaching by stating that glucose will be taken if which symptom develops? 1. Polyuria 2. Shakiness 3. Blurred vision 4. Fruity breath odor

2. Shakiness rationale: Shakiness is a sign of hypoglycemia, and it would indicate the need for food or glucose. Fruity breath odor, blurred vision, and polyuria are signs of hyperglycemia.

When caring for a client who is having clear drainage from his nares after transsphenoidal hypophysectomy, which action by the nurse is appropriate? 1. Lower the head of the bed. 2. Test the drainage for glucose. 3. Obtain a culture of the drainage. 4. Continue to observe the drainage.

2. Test the drainage for glucose. rationale: After hypophysectomy, the client should be monitored for rhinorrhea, which could indicate a cerebrospinal fluid (CSF) leak. If this occurs, the drainage should be collected and tested for glucose, indicating the presence of CSF. The head of the bed should not be lowered to prevent increased intracranial pressure. Clear nasal drainage would not indicate the need for a culture. Continuing to observe the drainage without taking action could result in a serious complication.

A nurse provides dietary instructions to a client with diabetes mellitus regarding the prescribed diabetic diet. Which statement, if made by the client, indicates the need for further teaching? 1. "I'll eat a balanced meal plan." 2. "I need to drink diet soft drinks." 3. "I need to buy special dietetic foods." 4. "I will snack on fruit instead of cake."

3. "I need to buy special dietetic foods." rationale: It is important to emphasize to the client and family that they are not eating a diabetic diet but rather following a balanced meal plan. Adherence to nutrition principles is an important component of diabetic management, and an individualized meal plan should be developed for the client. It is not necessary for the client to purchase special dietetic foods.

Which of the following statements made by the nursing student demonstrates an understanding of the hormone oxytocin? 1. "Production of oxytocin occurs in the ovaries." 2. "It is produced by the anterior pituitary gland." 3. "It causes contractions of the uterus during birth." 4. "Release of oxytocin stimulates the pancreas to produce insulin."

3. "It causes contractions of the uterus during birth." rationale: Oxytocin is produced by the posterior pituitary, not the anterior pituitary gland, and stimulates the uterus to produce contractions during birth. The ovaries are the endocrine glands that produce estrogen and progesterone. The pancreas produces insulin and other enzymes that aid digestion. Oxytocin does not stimulate the pancreas to produce insulin.

A client with Cushing's syndrome verbalizes concern to the nurse regarding the appearance of the buffalo hump that has developed. Which response by the nurse is appropriate? 1. "Don't be concerned, this problem can be covered with clothing." 2. "This is permanent, but looks are deceiving and not that important." 3. "Usually, these physical changes slowly improve following treatment." 4. "Try not to worry about it. There are other things to be concerned about."

3. "Usually, these physical changes slowly improve following treatment." rationale: The client with Cushing's syndrome should be reassured that most physical changes resolve with treatment. Options 1, 2, and 4 are not therapeutic responses.

A nurse is assisting with preparing a teaching plan for the client with diabetes mellitus regarding proper foot care. Which instruction should be included in the plan of care? 1. Soak the feet in hot water. 2. Avoid using soap to wash the feet. 3. Apply a moisturizing lotion to dry feet, but not between the toes. 4. Always have a podiatrist cut your toenails; never cut them yourself.

3. Apply a moisturizing lotion to dry feet, but not between the toes. rationale The client should use a moisturizing lotion on his or her feet, but should avoid applying the lotion between the toes. The client should also be instructed to not soak the feet and to avoid hot water to prevent burns. The client may cut the toenails straight across and even with the toe itself, but he or she should consult a podiatrist if the toenails are thick or hard to cut or if his or her vision is poor. The client should be instructed to wash the feet daily with a mild soap.

Following hypophysectomy, a client complains of being very thirsty and having to urinate frequently. The initial nursing action is to: 1. Document the complaints. 2. Increase fluid intake. 3. Check the urine specific gravity. 4. Check for urinary glucose.

3. Check the urine specific gravity. rationale: Following hypophysectomy, diabetes insipidus can occur temporarily because of antidiuretic hormone deficiency. This deficiency is related to surgical manipulation. The nurse should check the urine for specific gravity and report the results if they are less than 1.005. Urinary glucose and diabetes mellitus is not a concern here. In this situation, increasing fluid intake would require a health care provider's prescription. The client's complaint would be documented but not as an initial action.

A nurse is caring for a client with pheochromocytoma. Which data would indicate a potential complication associated with this disorder? 1. A urinary output of 50 mL/hr 2. A coagulation time of 5 minutes 3. Congestion heard on auscultation of the lungs 4. A blood urea nitrogen (BUN) level of 20 mg/dL

3. Congestion heard on auscultation of the lungs rationale: The complications associated with pheochromocytoma include hypertensive retinopathy and nephropathy, myocarditis, congestive heart failure (CHF), increased platelet aggregation, and stroke. Death can occur from shock, stroke, renal failure, dysrhythmias, or dissecting aortic aneurysm. Congestion heard on auscultation of the lungs is indicative of CHF. A urinary output of 50 mL/hr is an appropriate output; the nurse would become concerned if the output were less than 30 mL/hr. A coagulation time of 5 minutes is normal. A BUN level of 20 mg/dL is a normal finding.

A maternity nursing instructor asks a nursing student to identify the hormones that are produced by the ovaries. Which of the following, if identified by the student, indicates an understanding of the hormones produced by this endocrine gland? 1. Oxytocin 2. Luteinizing hormone (LH) 3. Estrogen and progesterone 4. Follicle-stimulating hormone (FSH)

3. Estrogen and progesterone rationale: The ovaries are the endocrine glands that produce estrogen and progesterone. Oxytocin is produced

A nurse is preparing to provide instructions to a client with Addison's disease regarding diet therapy. The nurse understands that which of the following diets would likely be prescribed for this client? 1. Low-protein die t2. Low-sodium diet 3. High-sodium diet 4. Low-carbohydrate diet

3. High-sodium diet rationale: A high-sodium, high-complex carbohydrate, and high-protein diet will be prescribed for the client with Addison's disease. To prevent excess fluid and sodium loss, the client is instructed to maintain an adequate salt intake of up to 8 g of sodium daily and to increase salt intake during hot weather, before strenuous exercise, and in response to fever, vomiting, or diarrhea.

Which nursing action would be appropriate to implement when a client has a diagnosis of pheochromocytoma? 1. Weigh the client. 2. Test the client's urine for glucose. 3. Monitor the client's blood pressure. 4. Palpate the client's skin to determine warmth.

3. Monitor the client's blood pressure. rationale: Hypertension is the major symptom that is associated with pheochromocytoma. The blood pressure status is monitored by taking the client's blood pressure. Glycosuria, weight loss, and diaphoresis are also clinical manifestations of pheochromocytoma, but hypertension is the major symptom.

A nurse assists in developing a plan of care for a client with hyperparathyroidism receiving calcitonin-human (Cibacalcin). Which outcome has the highest priority regarding this medication? 1. Relief of pain 2. Absence of side effects 3. Reaching normal serum calcium levels 4. Verbalization of appropriate medication knowledge

3. Reaching normal serum calcium levels rationale: Hypercalcemia can occur in clients with hyperparathyroidism, and calcitonin is used to lower plasma calcium level. The highest priority outcome in this client situation would be a reduction in serum calcium level. Option 1 is unrelated to this medication. Although options 2 and 4 are expected outcomes, they are not the highest priority for administering this medication.

A client with diabetes mellitus calls the clinic nurse to report that the blood glucose level is 150 mg/dL. After obtaining further data from the client, the nurse determines that the client ate lunch approximately 2 hours ago. The nurse would interpret these results to be: 1. Normal 2. Lower than the normal value 3. Slightly higher than the normal value 4. A value that indicates immediate health care provider notification

3. Slightly higher than the normal value rationale: Normal fasting blood glucose values range from 70 to 120 mg/dL. The 2-hour postprandial blood glucose level should be less than 140 mg/dL. In this situation, the blood glucose value was 150 mg/dL 2 hours after the client ate, which is slightly elevated above normal. This value does not require health care provider notification.

A client with type 1 diabetes mellitus is to begin an exercise program, and the nurse is providing instructions to the client regarding the program. Which of the following should the nurse include in the teaching plan? 1. Try to exercise before mealtime. 2. Administer insulin after exercising. 3. Take a blood glucose test before exercising. 4. Exercise should be performed during peak times of insulin.

3. Take a blood glucose test before exercising. rationale: A blood glucose test performed before exercising provides information to the client regarding the need to eat a snack first. Exercising during the peak times of insulin effect or before mealtime places the client at risk for hypoglycemia. Insulin should be administered as prescribed.

A nurse caring for a client scheduled for a transsphenoidal hypophysectomy to remove a tumor in the pituitary gland assists to develop a plan of care for the client. The nurse suggests including which specific information in the preoperative teaching plan? 1. Hair will need to be shaved. 2. Deep breathing and coughing will be needed after surgery. 3. Toothbrushing will not be permitted for at least 2 weeks following surgery. 4. Spinal anesthesia is used.

3. Toothbrushing will not be permitted for at least 2 weeks following surgery. rationale: Based on the location of the surgical procedure, spinal anesthesia would not be used. In addition, the hair would not be shaved. Although coughing and deep breathing are important, specific to this procedure is avoiding toothbrushing to prevent disruption of the surgical site. Also, coughing may disrupt the surgical site.

A preoperative client is scheduled for adrenalectomy to remove a pheochromocytoma. The nurse would most closely monitor which of the following items in the preoperative period? 1. Intake and output 2. Blood urea nitrogen (BUN) 3. Vital signs 4. Urine glucose and ketones

3. Vital signs rationale: Hypertension is the hallmark of pheochromocytoma. Severe hypertension can precipitate a stroke or sudden blindness. Although all the items are appropriate nursing assessments for the client with pheochromocytoma, the priority is to monitor the vital signs, especially the blood pressure.

A client with pheochromocytoma is scheduled for surgery and says to the nurse, "I'm not sure that surgery is the best thing to do." What response by the nurse is appropriate? 1. "I think you are making the right decision to have the surgery." 2. "You are very ill. Your health care provider has made the correct decision." 3. "There is no reason to worry. Your health care provider is a wonderful surgeon." 4. "You have concerns about the surgical treatment for your condition."

4. "You have concerns about the surgical treatment for your condition." rationale: Paraphrasing is restating the client's message in the nurse's own words. Option 4 addresses the therapeutic communication technique of paraphrasing. The client is reaching out for understanding. In option 3, the nurse is offering a false reassurance, and this type of response will block communication. Option 2 also represents a communication block because it reflects a lack of the client's right to an opinion. In option 1, the nurse is expressing approval, which can be harmful to a nurse-client relationship.

A nurse is monitoring a client receiving glipizide (Glucotrol). Which outcome indicates an ineffective response from the medication? 1. A decrease in polyuria 2. A decrease in polyphagia 3. A fasting plasma glucose of 100 mg/dL 4. A glycosylated hemoglobin level of 12%

4. A glycosylated hemoglobin level of 12% rationale: Glipizide (Glucotrol) is an oral hypoglycemic agent administered to decrease the serum glucose level and the signs and symptoms of hyperglycemia. Therefore, a decrease in both polyuria and polyphagia would indicate a therapeutic response. Laboratory values are also used to monitor a client's response to treatment. A fasting blood glucose level of 100 mg/dL is within normal limits. However, glycosylated hemoglobin of 12% indicates poor glycemic control.

A nursing student notes in the medical record that a client with Cushing's syndrome is experiencing body image disturbances. The need for additional education regarding this problem is identified when the nursing student suggests which nursing intervention? 1. Encouraging the client's expression of feelings 2. Evaluating the client's understanding of the disease process 3. Encouraging family members to share their feelings about the disease process 4. Evaluating the client's understanding that the body changes need to be dealt with

4. Evaluating the client's understanding that the body changes need to be dealt with rationale: Evaluating the client's understanding that the body changes that occur in this disorder need to be dealt with is an inappropriate nursing intervention. This option does not address the client's feelings. Options 1, 2, and 3 are appropriate because they address the client and family feelings regarding the disorder.

Which clinical manifestation should the nurse expect to note when assessing a client with Addison's disease? 1. Edema 2. Obesity 3. Hirsutism 4. Hypotension

4. Hypotension rationale: Common manifestations of Addison's disease include postural hypotension from fluid loss, syncope, muscle weakness, anorexia, nausea, vomiting, abdominal cramps, weight loss, depression, and irritability. The manifestations in options 1, 2, and 3 are not associated with Addison's disease.

A client is brought to the emergency department in an unresponsive state, and a diagnosis of hyperglycemic hyperosmolar nonketotic syndrome (HHNS) is made. The nurse who is assisting to care for the client obtains which of the following immediately in preparation for the treatment of this syndrome? 1. NPH insulin 2. A nasal cannula 3. Intravenous (IV) infusion of sodium bicarbonate 4. IV infusion of normal saline

4. IV infusion of normal saline rationale: The primary goal of treatment is to rehydrate the client to restore fluid volume and to correct electrolyte deficiency. IV fluid replacement is similar to that administered in diabetic ketoacidosis (DKA) and begins with IV infusion of normal saline. Regular insulin, not NPH insulin would be administered. The use of sodium bicarbonate to correct acidosis is avoided because it can precipitate a further drop in serum potassium levels. A nasal cannula for oxygen administration is not necessarily required to treat HHNS.

Which nursing measure would be effective in preventing complications in a client with Addison's disease? 1. Restricting fluid intake 2. Offering foods high in potassium 3. Checking family support systems 4. Monitoring the blood glucose

4. Monitoring the blood glucose rationale: The decrease in cortisol secretion that characterizes Addison's disease can result in hypoglycemia. Therefore monitoring the blood glucose would detect the presence of hypoglycemia so that it can be treated early to prevent complications. Fluid intake should be encouraged to compensate for dehydration. Potassium intake should be restricted because of hyperkalemia. Option 3 is not a priority for this client.

A nurse is collecting data regarding a client after a thyroidectomy and notes that the client has developed hoarseness and a weak voice. Which nursing action is appropriate? 1. Check for signs of bleeding. 2. Administer calcium gluconate. 3. Notify the registered nurse immediately. 4. Reassure the client that this is usually a temporary condition.

4. Reassure the client that this is usually a temporary condition. rationale: Weakness and hoarseness of the voice can occur as a result of trauma of the laryngeal nerve. If this develops, the client should be reassured that the problem will subside in a few days. Unnecessary talking should be discouraged. It is not necessary to notify the registered nurse immediately. These signs do not indicate bleeding or the need to administer calcium gluconate.

A female adult client with a history of chronic hyperparathyroidism admits to being noncompliant. Based on initial assessment findings, nurse Julia formulates the nursing diagnosis of Risk for injury. To complete the nursing diagnosis statement for this client, which "related-to" phrase should the nurse add? a. Related to bone demineralization resulting in pathologic fractures b. Related to exhaustion secondary to an accelerated metabolic rate c. Related to edema and dry skin secondary to fluid infiltration into the interstitial spaces d. Related to tetany secondary to a decreased serum calcium level

ANSWER: A Poorly controlled hyperparathyroidism may cause an elevated serum calcium level. This, in turn, may diminish calcium stores in the bone, causing bone demineralization and setting the stage for pathologic fractures and a risk for injury. Hyperparathyroidism doesn't accelerate the metabolic rate. A decreased thyroid hormone level, not an increased parathyroid hormone level, may cause edema and dry skin secondary to fluid infiltration into the interstitial spaces. Hyperparathyroidism causes hypercalcemia, not hypocalcemia; therefore, it isn't associated with tetany.

An agitated, confused female client arrives in the emergency department. Her history includes type 1 diabetes mellitus, hypertension, and angina pectoris. Assessment reveals pallor, diaphoresis, headache, and intense hunger. A stat blood glucose sample measures 42 mg/dl, and the client is treated for an acute hypoglycemic reaction. After recovery, nurse Lily teaches the client to treat hypoglycemia by ingesting: a. 2 to 5 g of a simple carbohydrate. b. 10 to 15 g of a simple carbohydrate. c. 18 to 20 g of a simple carbohydrate. d. 25 to 30 g of a simple carbohydrate.

ANSWER: B To reverse hypoglycemia, the American Diabetes Association recommends ingesting 10 to 15 g of a simple carbohydrate, such as three to five pieces of hard candy, two to three packets of sugar (4 to 6 tsp), or 4 oz of fruit juice. If necessary, this treatment can be repeated in 15 minutes. Ingesting only 2 to 5 g of a simple carbohydrate may not raise the blood glucose level sufficiently. Ingesting more than 15 g may raise it above normal, causing hyperglycemia.

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

ANSWER: B 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).

An ACTH stimulation test is commonly used to diagnose: a. Grave's disease b. Adrenal insufficiency and Addison's disease c. Cystic fibrosis d. Hashimoto's disease

ANSWER: B The ACTH stimulation test measures blood and urine cortisol before and after injection of ACTH. Persons with chronic adrenal insufficiency or Addison's disease generally do not respond with the expected increase in cortisol levels. An abnormal ACTH stimulation test may be followed with a CRH stimulation test to pinpoint the cause of adrenal insufficiency.

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

ANSWER: B 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.

For a male client with hyperglycemia, which assessment finding best supports a nursing diagnosis of Deficient fluid volume? a. Cool, clammy skin b. Distended neck veins c. Increased urine osmolarity d. Decreased serum sodium level

ANSWER: C In hyperglycemia, urine osmolarity (the measurement of dissolved particles in the urine) increases as glucose particles move into the urine. The client experiences glucosuria and polyuria, losing body fluids and experiencing fluid volume deficit. Cool, clammy skin; distended neck veins; and a decreased serum sodium level are signs of fluid volume excess, the opposite imbalance.

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

ANSWER: C 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.

All of the following are symptoms of Cushing's syndrome except: a. Severe fatigue and weakness b. Hypertension and elevated blood glucose c. A protruding hump between the shoulders d. Hair loss

ANSWER: D Cushing's syndrome also may cause fragile, thin skin prone to bruises and stretch marks on the abdomen and thighs as well as excessive thirst and urination and mood changes such as depression and anxiety. Women who suffer from high levels of cortisol often have irregular menstrual cycles or amenorrhea and present with hair on their faces, necks, chests, abdomens, and thighs.

Which of the following conditions is caused by long-term exposure to high levels of cortisol? a. Addison's disease b. Crohn's disease c. Adrenal insufficiency d. Cushing's syndrome

ANSWER: D Cushing's syndrome is a form of hypercortisolism. Risk factors for Cushing's syndrome are obesity, diabetes, and hypertension. Cushing's syndrome is most frequently diagnosed in persons ages 20 to 50 who have characteristic round faces, upper body obesity, large necks, and relatively thin limbs.

In explaining the condition to a client, a nurse would say that Cushing's syndrome is caused primarily by: Answers: A. Low levels of glucocorticoids B. Excess secretion of sodium C. Autoimmunity in the pancreas D. Elevated levels of cortisol

ANSWER: D Cushing's syndrome is caused by elevated levels of cortisol. Glucocorticoids tend to cause this.

Endocrine disorders may be triggered by all of the following except: a. Stress b. Infection c. Chemicals in the food chain and environment d. Cell phone use

ANSWER: D Endocrine function may be influenced by myriad factors. In addition to the above-mentioned, there is evidence that exposure to naturally occurring and man-made endocrine disruptors such as tributyltin, certain bioaccumulating chlorinated compounds, and phytoestrogens is widespread and in susceptible individuals, may trigger endocrine disorders.

When assessing a male client with pheochromocytoma, a tumor of the adrenal medulla that secretes excessive catecholamine, nurse April is most likely to detect: a. a blood pressure of 130/70 mm Hg .b. a blood glucose level of 130 mg/dl. c. bradycardia. d. a blood pressure of 176/88 mm Hg.

ANSWER: D Pheochromocytoma, a tumor of the adrenal medulla that secretes excessive catecholamine, causes hypertension, tachycardia, hyperglycemia, hypermetabolism, and weight loss. It isn't associated with the other options.

Nurse Kate is providing dietary instructions to a male client with hypoglycemia. To control hypoglycemic episodes, the nurse should recommend: a. Increasing saturated fat intake and fasting in the afternoon. b. Increasing intake of vitamins B and D and taking iron supplements. c. Eating a candy bar if light-headedness occurs. d. Consuming a low-carbohydrate, high-protein diet and avoiding fasting.

ANSWER: D To control hypoglycemic episodes, the nurse should instruct the client to consume a low-carbohydrate, high-protein diet, avoid fasting, and avoid simple sugars. Increasing saturated fat intake and increasing vitamin supplementation wouldn't help control hypoglycemia.

During preoperative teaching for a female client who will undergo subtotal thyroidectomy, the nurse should include which statement? a. "The head of your bed must remain flat for 24 hours after surgery." b. "You should avoid deep breathing and coughing after surgery." c. "You won't be able to swallow for the first day or two." d. "You must avoid hyperextending your neck after surgery."

ANSWER: D To prevent undue pressure on the surgical incision after subtotal thyroidectomy, the nurse should advise the client to avoid hyperextending the neck. The client may elevate the head of the bed as desired and should perform deep breathing and coughing to help prevent pneumonia. Subtotal thyroidectomy doesn't affect swallowing.

a client is admitted to the hospital with a medical DX of hyerthyroidism. When taking a history which information would be most significant? A. edema, intolerance to cold, lethargy b. peri-orbital edema, lethargy mask like face c. weight loss, intolerance to cold, muscle wasting d. weight loss, intolerance to heat, exophthalmos

ANSWER: D weight loss, intolerance to heat, exophthalmos

Jemma, who weighs 210 lb (95 kg) and has been diagnosed with hyperglycemia tells the nurse that her husband sleeps in another room because her snoring keeps him awake. The nurse notices that she has large hands and a hoarse voice. Which of the following would the nurse suspect as a possible cause of the client's hyperglycemia? a. Acromegaly b. Type 1 diabetes mellitus c. Hypothyroidism d. Deficient growth hormone

ANSWER:A Acromegaly, which is caused by a pituitary tumor that releases excessive growth hormone, is associated with hyperglycemia, hypertension, diaphoresis, peripheral neuropathy, and joint pain. Enlarged hands and feet are related to lateral bone growth, which is seen in adults with this disorder. The accompanying soft tissue swelling causes hoarseness and often sleep apnea. Type 1 diabetes is usually seen in children, and newly diagnosed persons are usually very ill and thin. Hypothyroidism isn't associated with hyperglycemia, nor is growth hormone deficiency.

The primary function of insuln is to: A. Lower blood glucose levels B. Produce melanin C. regulate the bodys metabolic rate D. stimulate release of digestive enzymes

ANSWER:A Lower Blood Glucose Levels

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

ANSWER:C 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.

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.

ASNWER: A 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.

in patients with pheochromocytoma there is a release of

high levels of epinephrine and norepinephrine

s/s of addison's disease include

•Muscle weakness, fatigue, •Weight loss, decreased appetite, hyperpigmentation (dark), Low BP, fainting, Salt craving, hypoglycemia, NDV, muscle or joint pains, Irritability, depression, Body hair loss or sexual dysfunction in women
