Thyroid, SAIDH, Diabetes, Graves', Cushing's, Addison's (1 of 2) NCLEX

The nurse is completing an assessment on a client who is being admitted for a diagnostic workup for primary hyperparathyroidism. Which client complaint would be characteristic of this disorder? Select all that apply. 1. Polyuria 2. Headache 3. Bone pain 4. Nervousness 5. Weight gain

1, 3 ~ The role of parathyroid hormone (PTH) in the body is to maintain serum calcium homeostasis. In hyperparathyroidism, PTH levels are high, which causes bone resorption (calcium is pulled from the bones). Hypercalcemia occurs with hyperparathyroidism. Elevated serum calcium levels produce osmotic diuresis and thus polyuria. This diuresis leads to dehydration (weight loss rather than weight gain). Loss of calcium from the bones causes bone pain. Options 2, 4, and 5 are not associated with hyperparathyroidism. Some gastrointestinal symptoms include anorexia, nausea, vomiting, and constipation.

The nurse is providing dietary instructions to help with diabetes control for a client newly diagnosed with diabetes mellitus who will be taking insulin. The nurse should provide the client with which best instruction? 1. Eat meals at approximately the same time each day. 2. Adjust mealtimes depending on blood glucose levels. 3. Vary mealtimes if insulin is not administered at the same time every day. 4. Avoid being concerned about the time of meals as long as snacks are taken on time.

1. ~ Mealtimes must be approximately the same each day to maintain a stable blood glucose level. The client should not be instructed that mealtimes can be varied depending on blood glucose levels, insulin administration, or consumption of snacks.

The home health nurse visits a client with a diagnosis of type 1 diabetes mellitus. The client relates a history of vomiting and diarrhea and tells the nurse that no food has been consumed for the last 24 hours. 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 monitor my blood glucose every 3 to 4 hours." 4. "I need to call the health care provider (HCP) because of these symptoms."

1. ~ When a client with diabetes mellitus is unable to eat normally because of illness, the client still should take the prescribed insulin or oral medication. The client should consume additional fluids and should notify the HCP. The client should monitor the blood glucose level every 3 to 4 hours. The client should also monitor the urine for ketones during illness.

The nurse is caring for a client after hypophysectomy and notes clear nasal drainage from the client's nostril. The nurse should take which initial action? 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. ~ After hypophysectomy, the client should be monitored for rhinorrhea, which could indicate a cerebrospinal fluid leak. If this occurs, the drainage should be collected and tested for the presence of cerebrospinal fluid. Cerebrospinal fluid contains glucose, and if positive, this would indicate that the drainage is cerebrospinal fluid. The head of the bed should remain elevated 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 client is admitted to an emergency department, and a diagnosis of myxedema coma is made. Which action should the nurse prepare to carry out initially? 1. Warm the client. 2. Maintain a patent airway. 3. Administer thyroid hormone. 4. Administer fluid replacement.

2. ~ Myxedema coma is a rare but serious disorder that results from persistently low thyroid production. Coma can be precipitated by acute illness, rapid withdrawal of thyroid medication, anesthesia and surgery, hypothermia, and the use of sedatives and opioid analgesics. In myxedema coma, the initial nursing action is to maintain a patent airway. Oxygen should be administered, followed by fluid replacement, keeping the client warm, monitoring vital signs, and administering thyroid hormones by the intravenous route.

A nurse is performing an admission assessment on a client with a diagnosis of pheochromocytoma. The nurse should assess for the major sign associated with pheochromocytoma by performing which action? 1. Obtaining the client's weight 2. Taking the client's blood pressure 3. Testing the client's urine for glucose 4. Palpating the skin for its temperature

2. ~ Pheochromocytoma is a catecholamine-producing tumor. Hypertension is the major sign associated with pheochromocytoma. Taking the client's blood pressure would assess the blood pressure status. Weight loss, glycosuria, and diaphoresis are also clinical manifestations of pheochromocytoma, yet hypertension is the major sign.

A client with suspected Cushing's syndrome is scheduled for adrenal venography. A nurse has provided instructions to the client regarding the test. Which statement by the client indicates a need for further instruction? 1. "I need to sign an informed consent." 2. "The insertion site will be locally anesthetized." 3. "I will be placed in a high-sitting position for the test." 4. "I may feel a burning sensation after the dye is injected."

3 ~ The test aids in determining whether signs and symptoms are caused by abnormalities in the adrenal gland. The nurse assesses the client for allergies to iodine before the test. The client is informed that the supine position is necessary to access the femoral vein. An informed consent form is required, the insertion site will be locally anesthetized, and the client will experience a transient burning sensation after the dye is injected.

A client is brought to the emergency department in an unresponsive state, and a diagnosis of hyperosmolar hyperglycemic syndrome is made. The nurse would immediately prepare to initiate which anticipated health care provider's prescription? 1. Endotracheal intubation 2. 100 units of NPH insulin 3. Intravenous infusion of normal saline 4. Intravenous infusion of sodium bicarbonate

3. ~ The primary goal of treatment in hyperosmolar hyperglycemic syndrome (HHS) is to rehydrate the client to restore fluid volume and to correct electrolyte deficiency. Intravenous (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. Intubation and mechanical ventilation are not required to treat HHS.

The nurse is caring for a client with a diagnosis of Cushing's syndrome. Which expected signs and symptoms should the nurse monitor for? Select all that apply. 1. Anorexia 2. Dizziness 3. Weight loss 4. Moon face 5. Hypertension 6. Truncal obesity

4, 5, 6 ~ A client with Cushing's syndrome may exhibit a number of different manifestations. These could include moon face, truncal obesity, and a buffalo hump fat pad. Other signs include hypokalemia, peripheral edema, hypertension, increased appetite, and weight gain. Dizziness is not part of the clinical picture for this disorder.

The nurse is caring for a client with a diagnosis of Addison's disease and is monitoring the client for signs of addisonian crisis. The nurse should assess the client for which manifestation that would be associated with this crisis? 1. Agitation 2. Diaphoresis 3. Restlessness 4. Severe abdominal pain

4. ~ Addisonian crisis is a serious life-threatening response to acute adrenal insufficiency that most commonly is precipitated by a major stressor. The client in addisonian crisis may demonstrate any of the signs and symptoms of Addison's disease, but the primary problems are sudden profound weakness; severe abdominal, back, and leg pain; hyperpyrexia followed by hypothermia; peripheral vascular collapse; coma; and renal failure. The remaining options do not identify clinical manifestations associated with addisonian crisis.

A client has begun medication therapy with propylthiouracil. The nurse should assess the client for which condition as an adverse effect of this medication? 1. Joint pain 2. Renal toxicity 3. Hyperglycemia 4. Hypothyroidism

4. ~ Propylthiouracil is prescribed for the treatment of hyperthyroidism. Excessive dosing with this agent may convert a hyperthyroid state to a hypothyroid state. If this occurs, the dosage should be reduced. Temporary administration of thyroid hormone may be required to treat the hypothyroid state. Propylthiouracil is not used for relief of joint pain. It does not cause renal toxicity or hyperglycemia.

The nurse is developing a plan of care for a client with Addison's disease. The nurse has identified a problem of risk for deficient fluid volume and identifies nursing interventions that will prevent this occurrence. Which nursing interventions should the nurse include in the plan of care? (SATA) 1. Monitor for changes in mentation. 2. Encourage an intake of low-protein foods. 3. Encourage an intake of low-sodium foods. 4. Encourage fluid intake of at least 3000 mL per day. 5. Monitor vital signs, skin turgor, and intake and output.

1, 4, 5 ~ The client at risk for deficient fluid volume should be encouraged to eat regular meals and snacks and to increase intake of sodium, protein, and complex carbohydrates and fluids. Oral replacement of sodium losses is necessary, and maintenance of adequate blood glucose levels is required. Mentation, vital signs, skin turgor and intake and output should be monitored for signs of fluid volume deficit.

A client has abnormal amounts of circulating thyronine (T3) and thyroxine (T4). While obtaining the health history, the nurse asks the client about dietary intake. Lack of which dietary element is most likely the cause? 1. Iodine 2. Calcium 3. Phosphorus 4. Magnesium

1. ~ Adequate dietary iodine is needed to produce T3 and T4. The other requirements for adequate T3 and T4 production are an intact thyroid gland and a functional hypothalamus-pituitary-thyroid feedback system. The remaining options are not responsible for the abnormal amounts of circulating T3 and T4.

A 33-year-old female client is admitted to the hospital with a tentative diagnosis of Graves' disease. Which symptom related to the menstrual cycle would the client be most likely to report during the initial assessment? 1. Amenorrhea 2. Menorrhagia 3. Metrorrhagia 4. Dysmenorrhea

1. ~ Amenorrhea or a decreased menstrual flow occurs in the client with Graves' disease. Menorrhagia, metrorrhagia, and dysmenorrhea are also disorders related to the female reproductive system; however, they are not typical manifestations of Graves' disease.

The health care provider prescribes a 24-hour urine collection for vanillylmandelic acid (VMA). The community health nurse visits the client at home and instructs the client in the procedure for the collection of the urine. Which statement, if made by the client, would indicate a need for further instruction? 1. "I can take medication if I need to during the collection." 2. "When I start the collection, I will urinate and discard that specimen." 3. "I will pour the urine in the collection bottle each time I urinate and refrigerate the urine." 4. "I will start the collection in 2 days. Starting now, I cannot eat or drink any tea, chocolate, vanilla, or fruit until the test is completed."

1. ~ Clients are reminded not to take medications for 2 to 3 days before a 24-hour urine collection for VMA. Because a 24-hour urine collection is a timed quantitative determination, it is essential that the client start the test with an empty bladder. Therefore, the client is instructed to void, discard the first urine, note the time, and start the test. The 24-hour urine specimen collection bottle must be kept on ice or refrigerated. For a VMA determination, the client is instructed to avoid tea, chocolate, vanilla, and all fruits for 2 days before urine collection begins.

A nurse is assessing the status of a client who returned to the surgical nursing unit after a parathyroidectomy procedure. The nurse would place highest priority on which assessment finding? 1. Laryngeal stridor 2. Difficulty voiding 3. Mild incisional pain 4. Absence of bowel sounds

1. ~ During the early postoperative period, the nurse carefully observes the client for signs of bleeding, which may cause swelling and compression of adjacent tissues. Laryngeal stridor results from compression of the trachea and is a harsh, high-pitched sound heard on inspiration and expiration. Laryngeal stridor is an acute emergency, necessitating immediate attention to avoid complete obstruction of the airway. The other options describe usual postoperative problems that are not life threatening.

The nurse is performing an assessment on a client with a diagnosis of hyperthyroidism. Which assessment finding should the nurse expect to note in this client? 1. Dry skin 2. Bulging eyeballs 3. Periorbital edema 4. Coarse facial features

2. ~ Hyperthyroidism is clinically manifested by goiter (increase in the size of the thyroid gland) and exophthalmos (bulging eyeballs). Other clinical manifestations include nervousness, fatigue, weight loss, muscle cramps, and heat intolerance. Additional signs found in this disorder include tachycardia; shortness of breath; excessive sweating; fine muscle tremors; thin, silky hair and thin skin; infrequent blinking; and a staring appearance.

A client has returned to the nursing unit after a thyroidectomy. The nurse notes that the client is complaining of tingling sensations around the mouth, fingers, and toes. On the basis of these findings, the nurse should next assess the results of which serum laboratory study? 1. Sodium 2. Calcium 3. Potassium 4. Magnesium

2. ~ After surgery on the thyroid gland, the client may experience a temporary calcium imbalance. This is due to transient malfunction of the parathyroid glands. The nurse also would assess for Chvostek's and Trousseau's signs. The correct treatment is administration of calcium gluconate or calcium lactate. The remaining options are unrelated to the client's complaints.

The nurse has developed a postoperative plan of care for a client who had a thyroidectomy and documents that the client is at risk for developing an ineffective breathing pattern. Which nursing intervention should the nurse include in the plan of care? 1. Maintain a supine position. 2. Monitor neck circumference every 4 hours. 3. Maintain a pressure dressing on the operative site. 4. Encourage deep-breathing exercises and vigorous coughing exercises.

2. ~ After thyroidectomy, neck circumference is monitored every 4 hours to assess for the occurrence of postoperative edema. The client should be placed in an upright position to facilitate air exchange. A pressure dressing is not placed on the operative site because it may restrict breathing. The nurse should monitor the dressing closely and should loosen the dressing if necessary. The nurse should assist the client with deep-breathing exercises, but coughing is minimized to prevent tissue damage and stress to the incision.

A client with diabetes mellitus demonstrates acute anxiety when admitted to the hospital for the treatment of hyperglycemia. What is the appropriate intervention to decrease the client's anxiety? 1. Administer a sedative. 2. Convey empathy, trust, and respect toward the client. 3. Ignore the signs and symptoms of anxiety, anticipating that they will soon disappear. 4. Make sure that the client is familiar with the correct medical terms to promote understanding of what is happening.

2. ~ Anxiety is a subjective feeling of apprehension, uneasiness, or dread. The appropriate intervention is to address the client's feelings related to the anxiety. Administering a sedative is not the most appropriate intervention and does not address the source of the client's anxiety. The nurse should not ignore the client's anxious feelings. Anxiety needs to be managed before meaningful client education can occur.

The home care nurse is visiting a client newly diagnosed with diabetes mellitus. The client tells the nurse that he is planning to eat dinner at a local restaurant this week. The client asks the nurse if eating at a restaurant will affect diabetic control and if this is allowed. Which nursing response is most appropriate? 1. "You are not allowed to eat in restaurants." 2. "You should order a half-portion meal and have fresh fruit for dessert." 3. "If you plan to eat in a restaurant, you need to skip the lunchtime meal." 4. "You should increase your daily dose of insulin by half on the day that you plan to eat in the restaurant."

2. ~ Clients with diabetes mellitus are instructed to make adjustments in their total daily intake to plan for meals at restaurants or parties. Some useful strategies include ordering a half-portion, salads with dressing on the side, fresh fruit for dessert, and baked or steamed entrees. Clients are not instructed to skip meals or increase their prescribed insulin dosage.

A client is diagnosed with Cushing's syndrome. When reviewing the recent laboratory results, the nurse should expect an excess of which substance? 1. Calcium 2. Cortisol 3. Epinephrine 4. Norepinephrine

2. ~ Cushing's syndrome is characterized by an excess of cortisol, a glucocorticoid. Glucocorticoids are produced by the adrenal cortex. Calcium would be decreased in this disorder. Epinephrine and norepinephrine are produced by the adrenal medulla.

The nurse is caring for a client who is 2 days postoperative from abdominal hysterectomy. The client has a history of diabetes mellitus and has been receiving regular insulin based on capillary blood glucose testing 4 times a day. A carbohydrate-controlled diet has been prescribed, but the client has not been eating. On entering the client's room, the nurse finds the client to be pale and diaphoretic. Which action is appropriate at this time? 1. Call a code to obtain needed assistance immediately. 2. Obtain a capillary blood glucose level and quickly perform a focused assessment. 3. Ask the unlicensed assistive personnel (UAP) to stay with the client while obtaining a carbohydrate snack for the client to eat. 4. Stay with the client and ask the UAP to call the health care provider (HCP) for a prescription for intravenous 50% dextrose.

2. ~ Diaphoresis and confusion are signs of moderate hypoglycemia. A likely cause of the client's change in condition could be related to the administration of insulin without the client's eating enough food. However, an assessment is necessary to confirm the presence of hypoglycemia. The nurse would obtain a capillary blood glucose level to confirm the hypoglycemia and quickly perform a focused assessment to determine the extent and cause of the client's condition. Once hypoglycemia is confirmed, the nurse stays with the client and asks the UAP to obtain the appropriate carbohydrate snack. A code is called if the client is not breathing or if the heart is not beating.

A client with type 1 diabetes mellitus calls the nurse to report recurrent episodes of hypoglycemia with exercising. Which statement by the client indicates an adequate understanding of the peak action of NPH insulin and exercise? 1. "I should not exercise since I am taking insulin." 2. "The best time for me to exercise is after breakfast." 3. "The best time for me to exercise is mid- to late afternoon." 4. "NPH is a basal insulin, so I should exercise in the evening."

2. ~ Exercise is an important part of diabetes management. It promotes weight loss, decreases insulin resistance, and helps to control blood glucose levels. A hypoglycemic reaction may occur in response to increased exercise, so clients should exercise either an hour after mealtime or after consuming a 10- to 15-gram carbohydrate snack, and they should check their blood glucose level before exercising. Option 1 is incorrect because clients with diabetes should exercise, though they should check with their health care provider before starting a new exercise program. Option 3 in incorrect; clients should avoid exercise during the peak time of insulin. NPH insulin peaks at 4 to 12 hours; therefore, afternoon exercise takes place during the peak of the medication. Options 4 is incorrect; NPH insulin in an intermediate-acting insulin, not a basal insulin.

A client with diabetes mellitus is at risk for a serious metabolic disorder from the breakdown of fats for conversion to glucose. The nurse should anticipate that which substance will be elevated? 1. Glucose 2. Ketones 3. Glucagon 4. Lactate dehydrogenase

2. ~ Ketones are a byproduct of fat metabolism. When this process occurs to an extreme, the resulting condition is called ketoacidosis. The remaining options are not associated with the breakdown of fats.

A client with medullary carcinoma of the thyroid has an excess function of the C cells of the thyroid gland. When reviewing the most recent laboratory results, the nurse should expect which electrolyte abnormality? 1. Sodium 2. Calcium 3. Potassium 4. Magnesium

2. ~ The C cells of the thyroid gland are helpful in maintaining normal plasma calcium levels. They do not affect the levels of sodium, potassium, or magnesium.

The 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 specific sign of this complication should be included on the list? 1. Shakiness 2. Increased thirst 3. Profuse sweating 4. Decreased urine output

2. ~ The classic signs of hyperglycemia include polydipsia, polyuria, and polyphagia. Profuse sweating and shakiness would be noted in a hypoglycemic condition.

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

2. ~ The client with Cushing's syndrome should be reassured that most physical changes resolve with treatment. All other options are not therapeutic responses.

A client visits the health care provider's office for a routine physical examination and reports a new onset of intolerance to cold. Since hypothyroidism is suspected, which additional information would be noted during the client's assessment? 1. Weight loss and tachycardia 2. Complaints of weakness and lethargy 3. Diaphoresis and increased hair growth 4. Increased heart rate and respiratory rate

2. ~ Weakness and lethargy are the most common complaints associated with hypothyroidism. Other common symptoms include intolerance to cold, weight gain, bradycardia, decreased respiratory rate, dry skin, and hair loss.

The nurse should include which interventions in the plan of care for a client with hyperthyroidism? (SATA) 1. Provide a warm environment for the client. 2. Instruct the client to consume a low-fat diet. 3. A thyroid-releasing inhibitor will be prescribed. 4. Encourage the client to consume a well-balanced diet. 5. Instruct the client that thyroid replacement therapy will be needed. 6. Instruct the client that episodes of chest pain are expected to occur.

3, 4 ~ The clinical manifestations of hyperthyroidism are the result of increased metabolism caused by high levels of thyroid hormone. Interventions are aimed at reduction of the hormones and measures to support the signs and symptoms related to an increased metabolism. The client often has heat intolerance and requires a cool environment. The nurse encourages the client to consume a well-balanced diet because clients with this condition experience increased appetite. Iodine preparations are used to treat hyperthyroidism. Iodine preparations decrease blood flow through the thyroid gland and reduce the production and release of thyroid hormone. Thyroid replacement is needed for hypothyroidism. The client would notify the health care provider if chest pain occurs because it could be an indication of an excessive medication dose.

A client has been diagnosed with pheochromocytoma. Which clinical manifestation is most indicative of this condition? 1. Water loss 2. Bradycardia 3. Hypertension 4. Decreased cardiac output

3. The client with pheochromocytoma has a benign or malignant tumor in the adrenal medulla. Because the medulla secretes epinephrine and norepinephrine, the client will exhibit signs related to excesses of these catecholamines, including tachycardia, increased cardiac output, and increased blood pressure. Vasoconstriction of the renal arteries triggers the renin-angiotensin system, resulting in water reabsorption and retention.

The nurse is caring for a client with Addison's disease. The client asks the nurse about the risks associated with this disease, specifically about addisonian crisis. Regarding prevention of this complication, how should the nurse inform the client? 1. "You can take either hydrocortisone or fludrocortisone for replacement." 2. "You need to take your fludrocortisone 3 times a day to prevent a crisis." 3. "You need to increase salt in your diet, particularly during stressful situations." 4. "You need to decrease your dosages of glucocorticoids and mineralocorticoids during stressful situations."

3. ~ Addison's disease is a result of adrenocortical insufficiency, and management is focused on treating the underlying cause. Hormone therapy is used for replacement. Hydrocortisone has both glucocorticoid and mineralocorticoid properties and needs to be taken 3 times daily, with two thirds of the daily dose taken on awakening. Fludrocortisone is taken once daily in the morning. Salt additives are necessary, particularly during times of stress, to compensate for excess heat or humidity as a result of the condition. There needs to be an increased dose of cortisol given for stressful situations such as surgery or hospitalization.

The nurse is monitoring a client for signs of hypocalcemia after thyroidectomy. Which sign or symptom, if noted in the client, would most likely indicate the presence of hypocalcemia? 1. Bradycardia 2. Flaccid paralysis 3. Tingling around the mouth 4. Absence of Chvostek's sign

3. ~ After thyroidectomy the nurse assesses the client for signs of hypocalcemia and tetany. Early signs include tingling around the mouth and in the fingertips, muscle twitching or spasms, palpitations or arrhythmias, and Chvostek's and Trousseau's signs. Bradycardia, flaccid paralysis, and absence of Chvostek's sign are not signs of hypocalcemia.

A nurse is caring for a client with a dysfunctional thyroid gland and is concerned that the client will exhibit a sign of thyroid storm. Which is an early indicator of this complication? 1. Bradycardia 2. Constipation 3. Hyperreflexia 4. Low-grade temperature

3. ~ Clinical manifestations of thyroid storm include a fever as high as 106°F, hyperreflexia, abdominal pain, diarrhea, dehydration rapidly progressing to coma, severe tachycardia, extreme vasodilation, hypotension, atrial fibrillation, and cardiovascular collapse.

The nurse is providing instructions regarding home care measures to a client with diabetes mellitus and instructs the client about the causes of hypoglycemia. The nurse determines that additional instruction is needed if the client identifies which as a cause of hypoglycemia? 1. Omitted meals 2. Increased intensity of activity 3. Decreased daily insulin dosage 4. Inadequate amount of fluid intake

3. ~ Decreasing the dose of insulin will lead to hyperglycemia. Causes for hypoglycemic reactions include delayed consumption of meals and lack of necessary amounts of food. Other causes include the administration of excessive insulin or oral hypoglycemic medications, vomiting associated with illness, and strenuous exercise, which may potentiate the action of insulin.

A hospitalized client is experiencing an episode of hypoglycemia. The client is lethargic and has no available intravenous (IV) access. Which medication should the nurse anticipate administering? 1. Insulin 2. Cortisone 3. Glucagon 4. Epinephrine

3. ~ Glucagon, a natural hormone secreted by the pancreas, is available as a subcutaneous injection to be given when a quick response to severe hypoglycemia is needed. Glucagon is useful in the unconscious hypoglycemic client without established IV access. The remaining options are incorrect treatments.

A nurse is caring for a client who had a thyroidectomy 1 day ago. Which client laboratory data should the nurse identify as a possible complication of thyroid surgery? 1. Increased serum sodium level 2. Increased serum glucose level 3. Decreased serum calcium level 4. Decreased serum albumin level

3. ~ Hypocalcemia may occur if the parathyroid glands are removed or damaged or if their blood supply is impaired during thyroid surgery, resulting in decreased parathyroid hormone (PTH) levels and leading to decreased serum calcium levels. Serum sodium, albumin, and glucose levels are not affected by thyroid surgery.

The nurse is instructing a client with Cushing's syndrome on follow-up care. Which of these client statements would indicate a need for further instruction? 1. "I should avoid contact sports." 2. "I should check my ankles for swelling." 3. "I need to avoid foods high in potassium." 4. "I need to check my blood glucose regularly."

3. ~ Hypokalemia is a common characteristic of Cushing's syndrome, and the client is instructed to consume foods high in potassium. Clients with this condition experience activity intolerance, osteoporosis, and frequent bruising. Fluid volume excess results from water and sodium retention. Hyperglycemia is caused by an increased cortisol secretion.

The nurse performs a physical assessment on a client with type 2 diabetes mellitus. Findings include a fasting blood glucose level of 120 mg/dL (6.8 mmol/L), temperature of 101°F (38.3°C), pulse of 102 beats/minute, respirations of 22 breaths/minute, and blood pressure of 142/72 mm Hg. Which finding would be the priority concern to the nurse? 1. Pulse 2. Respiration 3. Temperature 4. Blood pressure

3. ~ In the client with type 2 diabetes mellitus, an elevated temperature may indicate infection. Infection is a leading cause of hyperosmolar hyperglycemic syndrome in the client with type 2 diabetes mellitus. The other findings are within normal limits.

A nurse is assessing a client who has had cranial surgery and is at risk for development of diabetes insipidus. The nurse would assess for which signs or symptoms that could indicate development of this complication? 1. Diarrhea 2. Infection 3. Polydipsia 4. Weight gain

3. ~ Polydipsia and polyuria are classic symptoms of diabetes insipidus. The urine is pale, and the specific gravity is low. Diarrhea is not indicative of the complication. Infection is not associated with diabetes insipidus. Anorexia and weight loss also may occur.

The nurse is reviewing the postoperative prescriptions for a client who had a transsphenoidal hypophysectomy. Which health care provider's (HCP's) prescriptions, if noted on the record, would indicate the need for clarification? 1. Assess vital signs and neurological status. 2. Instruct the client to avoid blowing his nose. 3. Apply a loose dressing if any clear drainage is noted. 4. Instruct the client about the need for a MedicAlert bracelet.

3. ~ The nurse should observe for clear nasal drainage; constant swallowing; and a severe, persistent, generalized, or frontal headache. These signs and symptoms indicate cerebrospinal fluid leak into the sinuses. If clear drainage is noted after this procedure, the HCP needs to be notified. Therefore, clarification is needed regarding application of a loose dressing. The remaining options indicate appropriate postoperative interventions.

The nurse is developing a plan of care for a client who is scheduled for a thyroidectomy. The nurse focuses on psychosocial needs, knowing that which is likely to occur in the client? 1. Infertility 2. Gynecomastia 3. Sexual dysfunction 4. Body image changes

4. ~ Because of the location of the incision in the neck area, many clients are afraid of thyroid surgery for fear of having a visible large scar postoperatively. Having all or part of the thyroid gland removed will not cause the client to experience gynecomastia. Sexual dysfunction and infertility could occur if the entire thyroid is removed and the client is not placed on thyroid replacement medications.

A client is admitted with suspected diabetic ketoacidosis (DKA). Which clinical manifestations best support a diagnosis of DKA? 1. Blood glucose 500 mg/dL (27.8 mmol/L); arterial blood gases: pH 7.30, PaCo2 50, HCO3- 26. 2. Blood glucose 400 mg/dL (22.2 mmol/L); arterial blood gases: pH 7.38, PaCo2 40, HCO3- 22. 3. Blood glucose 450 mg/dL (25.0 mmol/L); arterial blood gases: pH 7.48, PaCo2 39, HCO3- 29. 4. Blood glucose 350 mg/dL (19.4 mmol/L); arterial blood gases: pH 7.28, PaCo2 30, HCO3- 14.

4. ~ DKA is caused by a profound deficiency of insulin and is characterized by hyperglycemia (blood glucose level greater than or equal to 250 mg/dL [13.9 mmol/L]), ketosis (ketones in urine or serum), metabolic acidosis, and dehydration. The correct option is 4, as it represents an elevated blood glucose and the arterial blood gases (ABGs) indicate metabolic acidosis. Option 1 is incorrect, as the ABGs indicate respiratory acidosis; option 2 is incorrect, as the ABG values are within normal; and option 3 is incorrect, as the ABGs indicate metabolic alkalosis.

The nurse is providing education to a client with type 2 diabetes mellitus. The nurse explains in layperson's language the physiological mechanism behind hypoglycemia. Which response by the client determines that teaching has been successful? 1. "My body cannot make insulin." 2. "My body has decreased epinephrine levels." 3. "My body decreases release of cortisol, which is a stress hormone." 4. "My body increases glucagon production to fight low blood sugars."

4. ~ Glucagon is secreted from the alpha cells in the pancreas in response to declining blood glucose levels. At the same time, hypoglycemia triggers increased cortisol release, increased epinephrine release, and decreased secretion of insulin. Options 1, 2, and 3 are not physiological mechanisms that take place to combat the decrease in the blood glucose level.

A client with type 2 diabetes mellitus is complaining of polydipsia, polyuria, weight loss, and weakness. Laboratory results indicate a blood glucose level of 800 mg/dL (45.7 mmol/L) and nonketosis. The nurse reviews the health care provider's documentation and expects to note which diagnosis? 1. Hypoglycemia 2. Pheochromocytoma 3. Diabetic ketoacidosis (DKA) 4. Hyperosmolar hyperglycemic syndrome (HHS)

4. ~ HHS is seen primarily in clients with type 2 diabetes mellitus, who experience a relative deficiency of insulin. The onset of signs and symptoms may be gradual. Manifestations may include polyuria, polydipsia, dehydration, mental status alterations, weight loss, and weakness. In HHS, the client is nonketotic. The clinical manifestations noted in the question are not signs of hypoglycemia. Pheochromocytoma is not related to these clinical manifestations. DKA typically occurs in type 1 diabetes mellitus.

A client with type 2 diabetes mellitus has a blood glucose level greater than 600 mg/dL (34.3 mmol/L) and is complaining of polydipsia, polyuria, weight loss, and weakness. The nurse reviews the health care provider's documentation and expects to note which diagnosis? 1. Hypoglycemia 2. Pheochromocytoma 3. Diabetic ketoacidosis (DKA) 4. Hyperosmolar hyperglycemic syndrome (HHS)

4. ~ HHS is seen primarily in clients with type 2 diabetes mellitus, who experience a relative deficiency of insulin. The onset of signs and symptoms may be gradual. Manifestations may include polyuria, polydipsia, dehydration, mental status alterations, weight loss, and weakness. The clinical manifestations noted in the question are not signs of hypoglycemia. Pheochromocytoma is not related to these clinical manifestations. DKA typically occurs in type 1 diabetes mellitus.

A client arrives in the hospital emergency department complaining of severe thirst and polyuria. The client tells the nurse that she has a history of diabetes mellitus. A blood glucose level is drawn, and the result is 685 mg/dL (39.1 mmol/L). Which intervention should the nurse anticipate to be prescribed initially for the client? 1. Glyburide via the oral route 2. Glucagon via the subcutaneous route 3. Insulin aspart via the subcutaneous route 4. Regular insulin via the intravenous (IV) route

4. ~ The client is most likely in diabetic ketoacidosis (DKA). Regular insulin via the IV route is the preferred treatment for DKA. Regular insulin is a short-acting insulin and can be given intravenously; it is titrated to the client's high blood glucose levels. Glucagon is used to treat hypoglycemia, and glyburide is an oral hypoglycemic agent used to treat type 2 diabetes mellitus. Insulin aspart is a short-acting insulin and is not appropriate for the emergency treatment of DKA.

A client has been diagnosed with Cushing's syndrome. The nurse should assess the client for which expected manifestations of this disorder? 1. Dizziness 2. Weight loss 3. Hypoglycemia 4. Truncal obesity

4. ~ The client with Cushing's syndrome may exhibit a number of different manifestations. These may include moon face, truncal obesity, and a "buffalo hump" fat pad. Other signs include hyperglycemia, hypernatremia, hypocalcemia, peripheral edema, hypertension, increased appetite, and weight gain. Dizziness is not part of the clinical picture for this disorder.

A client has undergone a 2-hour oral glucose tolerance test (OGTT). Which of the listed glucose levels is compatible with diabetes mellitus at the conclusion of the test? 1. 80 mg/dL (4.57 mmol/L) 2. 110 mg/dL (6.0 mmol/L) 3. 130 mg/dL (7.42 mmol/L) 4. 160 mg/dL (9.14 mmol/L)

4. ~ The normal reference values for OGTTs are lower than 140 mg/dL (8 mmol/L) at 120 minutes; lower than 200 mg/dL (11.4 mmol/L) at 30, 60, and 90 minutes; and lower than 115 mg/dL (6.57 mmol/L) in the fasting state. A glucose level of 160 mg/dL (9.14 mmol/L) is higher than the normal reference range, so therefore is the correct answer.

The nurse is performing an assessment on a client with a diagnosis of Cushing's syndrome. Which should the nurse expect to note on assessment of the client? 1. Skin atrophy 2. The presence of sunken eyes 3. Drooping on 1 side of the face 4. A rounded "moonlike" appearance to the face

4. ~ With excessive secretion of adrenocorticotropic hormone (ACTH) and chronic corticosteroid use, the person with Cushing's syndrome develops a rounded moonlike face; prominent jowls; red cheeks; and hirsutism on the upper lip, lower cheek, and chin. The remaining options are not associated with the assessment findings in Cushing's syndrome.
