Endocrine

The nurse is preparing a plan of care for a client with diabetes mellitus who has hyperglycemia. The nurse places priority on which client problem?

2.Inadequate fluid volume An increased blood glucose level will cause the kidneys to excrete the glucose in the urine. This glucose is accompanied by fluids and electrolytes, causing an osmotic diuresis leading to dehydration. This fluid loss must be replaced when it becomes severe. Options 1, 3, and 4 are not related specifically to the information in the question.

The nurse is developing a plan of care for a client with Cushing's syndrome. The nurse documents a client problem of excess fluid volume. Which nursing actions should be included in the care plan for this client? Select all that apply.

1,2,3 The client with Cushing's syndrome and a problem of excess fluid volume should be on daily weights and intake and output and have extremities assessed for edema. He or she should be maintained on a high-potassium, low-sodium diet. Decreased sodium intake decreases renal retention of sodium and water.

A preoperative client is scheduled for adrenalectomy to remove a pheochromocytoma. The nurse would most closely monitor which item in the preoperative period?

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

The nurse is caring for a client with a serum phosphorus level of 5.0 mg/dL (1.61 mmol/L). What other laboratory value might the nurse expect to note in the medical record?

1.Calcium level of 8 mg/dL (2.0 mmol/L) Parathyroid hormone is responsible for maintaining serum calcium and phosphorus levels within normal range. Therefore, if these laboratory values are altered, this suggests dysfunction of the parathyroid gland. When calcium levels are elevated (normal is 9 to 10.5 mg/dL [2.25 to 2.75 mmol/L]) and phosphorous levels are decreased (normal is 3.0 to 4.5 mg/dL [0.97 to 1.45 mmol/L]), this suggests hyperparathyroidism. If the phosphorus level is elevated, the nurse should expect the calcium level to be low. Therefore, option 1 is the correct answer.

A nurse is assessing the glycemic status of a client with diabetes mellitus. Which sign or symptom would indicate that the client is developing hyperglycemia?

1.Polyuria Classic signs and symptoms of hyperglycemia include polydipsia, polyuria, and polyphagia. It is important to regularly assess the client for hyperglycemia to prevent the development of more serious complications, such as diabetic ketoacidosis. The remaining options are not manifestations of hyperglycemia.

A client with diabetes mellitus has been instructed in the dietary exchange system. The client asks the nurse if bacon is allowed in the diet. Which nursing response is most appropriate?

4."One strip of bacon may be eaten if you eliminate 1 teaspoon of butter." Bacon is a component of the fat group in the exchange system. One teaspoon of butter is equal to 1 teaspoon of margarine, 1 teaspoon of any oil, 1 tablespoon of salad dressing, 1 strip of bacon, 5 large olives, or 10 whole peanuts.

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?

4.A rounded "moonlike" appearance to the face 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.

The nurse is caring for a client admitted to the emergency department with diabetic ketoacidosis (DKA). In the acute phase, the nurse plans for which priority intervention?

4.Administer short-duration insulin intravenously. Lack of insulin (absolute or relative) is the primary cause of DKA. Treatment consists of insulin administration (short- or rapid-acting), intravenous fluid administration (normal saline initially, not 5% dextrose), and potassium replacement, followed by correcting acidosis. Cardiac monitoring is important due to alterations in potassium levels associated with DKA and its treatment, but applying an electrocardiogram monitor is not the priority action.

A client with a diagnosis of addisonian crisis is being admitted to the intensive care unit. Which findings will the interprofessional health care team focus on? Select all that apply.

1,3 In Addison's disease, also known as adrenal insufficiency, destruction of the adrenal gland leads to decreased production of adrenocortical hormones, including the glucocorticoid cortisol and the mineralocorticoid aldosterone. Addisonian crisis, also known as acute adrenal insufficiency, occurs when there is extreme physical or emotional stress and lack of sufficient adrenocortical hormones to manage the stressor. Addisonian crisis is a life-threatening emergency. One of the roles of endogenous cortisol is to enhance vascular tone and vascular response to the catecholamines epinephrine and norepinephrine. Hypotension occurs when vascular tone is decreased and blood vessels cannot respond to epinephrine and norepinephrine. The role of aldosterone in the body is to support the blood pressure by holding salt and water and excreting potassium. When there is insufficient aldosterone, salt and water are lost and potassium builds up; this leads to hypotension from decreased vascular volume, hyponatremia, and hyperkalemia. The remaining options are not associated with addisonian crisis.

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.

1,3 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 monitoring a client who was diagnosed with type 1 diabetes mellitus and is being treated with NPH and regular insulin. Which manifestations would alert the nurse to the presence of a possible hypoglycemic reaction? Select all that apply.

1,3,4 Decreased blood glucose levels produce autonomic nervous system symptoms, which are manifested classically as nervousness, irritability, and tremors. Option 5 is more likely to occur with hyperglycemia. Options 2 and 6 are unrelated to the manifestations of hypoglycemia. In hypoglycemia, usually the client feels hunger.

Which findings should raise suspicion to the nurse that a head-injured client may be experiencing diabetes insipidus? Select all that apply.

1,4,6 Signs of diabetes insipidus include low urine specific gravity (<1.005), high serum osmolality (>300 mOsm/kg of water), and increased urine output from a deficiency of antidiuretic hormone (ADH). Options 2, 3, and 5 are not characteristic of diabetes insipidus.

The primary 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." 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.

The nurse is teaching a client with hyperparathyroidism how to manage the condition at home. Which response by the client indicates the need for additional teaching?

1."I should consume less than 1 liter of fluid per day." In hyperparathyroidism, clients experience excess parathyroid hormone (PTH) secretion. A role of PTH in the body is to maintain serum calcium homeostasis. When PTH levels are high, there is excess bone resorption (calcium is pulled from the bones). In clients with elevated serum calcium levels, there is a risk of nephrolithiasis. One to two liters of fluids daily should be encouraged to protect the kidneys and decrease the risk of nephrolithiasis. Moderate physical activity, particularly weight-bearing activity, minimizes bone resorption and helps protect against pathological fracture. Walking, as an exercise, should be encouraged in the client with hyperparathyroidism. Even though serum calcium is already high, clients should follow a moderate-calcium diet, because a low-calcium diet will surge PTH. Calcium causes constipation, so a diet high in fiber is recommended. Alendronate is a bisphosphate that inhibits bone resorption. In bone resorption, bone is broken down and calcium is deposited into the serum.

The nurse is monitoring a client newly diagnosed with diabetes mellitus for signs of complications. Which sign or symptom, if exhibited in the client, indicates that the client is at risk for chronic complications of diabetes if the blood glucose is not adequately managed?

1.Polyuria Chronic hyperglycemia, resulting from poor glycemic control, contributes to the microvascular and macrovascular complications of diabetes mellitus. Classic symptoms of hyperglycemia include polydipsia, polyuria, and polyphagia. Diaphoresis may occur in hypoglycemia. Hypoglycemia is an acute complication of diabetes mellitus; however, it does not predispose a client to the chronic complications of diabetes mellitus. Therefore, option 2 can be eliminated because this finding is characteristic of hypoglycemia. Options 3 and 4 are not associated with diabetes mellitus.

A client with an endocrine disorder has experienced recent weight loss and exhibits tachycardia. Based on the clinical manifestations, the nurse should suspect dysfunction of which endocrine gland?

1.Thyroid The thyroid gland is responsible for a number of metabolic functions in the body. Among these are metabolism of nutrients such as fats and carbohydrates. Increased metabolic function places a demand on the cardiovascular system for a higher cardiac output. A client with increased activity of the thyroid gland will experience weight loss from the higher metabolic rate and will have an increased pulse rate. The anterior pituitary gland produces growth hormone, luteinizing hormone, and follicle-stimulating hormone. Antidiuretic hormone (ADH) and oxytocin are secreted by the posterior pituitary gland. Both ADH and oxytocin are synthesized by the hypothalamus and stored in the posterior pituitary gland. These hormones are released as needed into the bloodstream. Parathyroid hormone is responsible for maintaining serum calcium and phosphorus levels within normal range. The adrenal cortex is responsible for the production of glucocorticoids and mineralocorticoids.

The nurse is preparing to care for a client after parathyroidectomy. The nurse should plan for which action for this client?

2.Administer a continuous mist of room air or oxygen. Humidification of air or oxygen helps to liquefy mucous secretions and promotes easier breathing after parathyroidectomy. Pooling of thick mucous secretions in the trachea, bronchi, and lungs will cause respiratory obstruction. The client will not necessarily have an endotracheal tube in place. Tympanic temperatures can be taken. Semi-Fowler's position is the position of choice to assist in lung expansion and prevent edema. Rectal temperatures only are not required.

The clinic nurse is providing instructions to a client with diabetes mellitus about the signs and symptoms of hypoglycemia. The nurse should tell the client that which would be noted in a hypoglycemic reaction?

2.Hunger Signs and symptoms of hypoglycemia include hunger, nervousness, anxiety, dizziness, blurred vision, sweaty palms, confusion, and tingling and numbness around the mouth. Polydipsia (thirst) and increased urine output are noted in the client with hyperglycemia.

The nurse should include which interventions in the plan of care for a client with hypothyroidism? Select all that apply.

3,4,6 The clinical manifestations of hypothyroidism are the result of decreased metabolism from low levels of thyroid hormone. Interventions are aimed at replacement of the hormone and providing measures to support the signs and symptoms related to decreased metabolism. The client often has cold intolerance and requires a warm environment. The nurse encourages the client to consume a well-balanced diet that is low in fat for weight reduction and high in fluids and high-fiber foods to prevent constipation. Iodine preparations may be used to treat hyperthyroidism. Iodine preparations decrease blood flow through the thyroid gland and reduce the production and release of thyroid hormone; they are not used to treat hypothyroidism. The client is instructed to notify the PHCP if chest pain occurs because it could be an indication of overreplacement of thyroid hormone.

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?

3."I will be placed in a high-sitting position for the test." 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 nurse has provided dietary instructions to a client with Addison's disease. Which statement made by the client indicates that the client understands the instructions?

3."I will maintain a normal sodium intake in my diet." A high-complex carbohydrate, 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 a normal salt intake daily (3 g) and to increase salt intake during hot weather, before strenuous exercise, and in response to fever, vomiting, or diarrhea. A high-fat diet is not prescribed.

A client newly diagnosed with diabetes mellitus is instructed by the primary health care provider to obtain glucagon for emergency home use. The client asks a home care nurse about the purpose of the medication. What is the nurse's best response to the client's question?

3."It is for the times when your blood glucose is too low from too much insulin." Glucagon is used to treat hypoglycemia resulting from insulin overdose. The family of the client is instructed in how to administer the medication. In an unconscious client, arousal usually occurs within 20 minutes of glucagon injection. When consciousness has been regained, oral carbohydrates should be given. Lipoatrophy and lipohypertrophy result from insulin injections.

The nurse is performing an assessment on a client with pheochromocytoma. Which assessment data would indicate a potential complication associated with this disorder?

3.A heart rate that is 90 beats/minute and irregular Pheochromocytoma is a catecholamine-producing tumor usually found in the adrenal medulla, but extra-adrenal locations include the chest, bladder, abdomen, and brain; it is typically a benign tumor but can be malignant. Excessive amounts of epinephrine and norepinephrine are secreted. The complications associated with pheochromocytoma include hypertensive retinopathy and nephropathy, myocarditis, increased platelet aggregation, and stroke. Death can occur from shock, stroke, kidney failure, dysrhythmias, or dissecting aortic aneurysm. An irregular heart rate indicates the presence of a dysrhythmia. A coagulation time of 5 minutes is normal. A urinary output of 50 mL/hour is an adequate output. A blood urea nitrogen level of 20 mg/dL (7.1 mmol/L) is a normal finding.

A client has just been admitted to the nursing unit following thyroidectomy. Which assessment is the priority for this client?

3.Audible stridor Thyroidectomy is the removal of the thyroid gland, which is located in the anterior neck. It is very important to monitor airway status, as any swelling to the surgical site could cause respiratory distress. Although all of the options are important for the nurse to monitor, the priority nursing action is to monitor the airway.

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?

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

A nurse is caring for a client with thyrotoxicosis who is at risk for the development of thyroid storm. To detect this complication, the nurse should assess for which sign or symptom?

3.Hypertension Thyroid storm is an acute, life-threatening condition that occurs in a client with uncontrollable hyperthyroidism. Clinical manifestations of thyroid storm include systolic hypertension, tachycardia, diarrhea, and a fever as high as 106º F. Other manifestations include abdominal pain, dehydration, extreme vasodilation, stupor rapidly progressing to coma, atrial fibrillation, and cardiovascular collapse. Bradycardia, constipation, and low-grade temperature are not a part of the clinical picture in thyroid storm.

A client is admitted to a hospital with a diagnosis of diabetic ketoacidosis (DKA). The initial blood glucose level is 950 mg/dL (52.9 mmol/L). A continuous intravenous (IV) infusion of short-acting insulin is initiated, along with IV rehydration with normal saline. The serum glucose level is now decreased to 240 mg/dL (13.3 mmol/L). The nurse would next prepare to administer which medication?

3.IV fluids containing dextrose Emergency management of DKA focuses on correcting fluid and electrolyte imbalances and normalizing the serum glucose level. If the corrections occur too quickly, serious consequences, including hypoglycemia and cerebral edema, can occur. During management of DKA, when the blood glucose level falls to 250 to 300 mg/dL (13.9 to 16.7 mmol/L), the IV infusion rate is reduced and a dextrose solution is added to maintain a blood glucose level of about 250 mg/dL (13.9 mmol/L), or until the client recovers from ketosis. Fifty percent dextrose is used to treat hypoglycemia. NPH insulin is not used to treat DKA. Phenytoin is not a usual treatment measure for DKA.

A client is admitted to a hospital with a diagnosis of diabetic ketoacidosis (DKA). The initial blood glucose level is 950 mg/dL (54.2 mmol/L). A continuous intravenous (IV) infusion of short-acting insulin is initiated, along with IV rehydration with normal saline. The serum glucose level is now decreased to 240 mg/dL (13.7 mmol/L). The nurse would next prepare to administer which medication?

3.IV fluids containing dextrose Emergency management of DKA focuses on correcting fluid and electrolyte imbalances and normalizing the serum glucose level. If the corrections occur too quickly, serious consequences, including hypoglycemia and cerebral edema, can occur. During management of DKA, when the blood glucose level falls to 250 to 300 mg/dL (14.2 to 17.1 mmol/L), the IV infusion rate is reduced and a dextrose solution is added to maintain a blood glucose level of about 250 mg/dL (14.2 mmol/L), or until the client recovers from ketosis. Fifty percent dextrose is used to treat hypoglycemia. NPH insulin is not used to treat DKA. Phenytoin is not a usual treatment measure for DKA.

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 primary health care provider's prescription?

3.Intravenous infusion of normal saline 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.

A client with a history of diabetes mellitus has a fingerstick blood glucose level of 460 mg/dL (25.6 mmol/L). The home care nurse anticipates that which additional finding would be present with further testing if the client is experiencing diabetic ketoacidosis (DKA)?

3.Presence of ketone bodies DKA is marked by the presence of excessive ketone bodies. As a result of the acidosis, the pH and serum bicarbonate level would decrease. Hyponatremia is not related to DKA.

A client has just been admitted to the nursing unit following thyroidectomy. Which assessment is the priority for this client?

3.Respiratory distress Thyroidectomy is the removal of the thyroid gland, which is located in the anterior neck. It is very important to monitor airway status, as any swelling to the surgical site could cause respiratory distress. Although all of the options are important for the nurse to monitor, the priority nursing action is to monitor the airway.

The nurse performs a physical assessment on a client with type 2 diabetes mellitus. Findings include a fasting blood glucose level of 70 mg/dL (3.9 mmol/L). Which finding would be the priority concern to the nurse?

3.Temperature 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 multidisciplinary health care team is developing a plan of care for a client with hyperparathyroidism. The nurse should include which priority intervention in the plan of care?

3.Walk down the hall for 15 minutes 3 times a day. Mobility of the client with hyperparathyroidism should be encouraged as much as possible because of the calcium imbalance that occurs in this disorder and the predisposition to the formation of renal calculi. Fluids should not be restricted. Discussing the use of medications is not the priority with this client.

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?

4.Body image changes 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.

The nurse has documented the problem of body image distortion for a client with a diagnosis of Cushing's syndrome. The nurse identifies nursing interventions related to this problem and includes these interventions in the plan of care. Which nursing intervention is inappropriate?

4.Encourage the client to recognize that the body changes need to be dealt with. Encouraging the client to understand 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. The remaining options are appropriate because they address the client and family feelings regarding the disorder.

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 primary health care provider's documentation and expects to note which diagnosis?

4.Hyperosmolar hyperglycemic syndrome (HHS) 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.

An external insulin pump is prescribed for a client with diabetes mellitus. When the client asks the nurse about the functioning of the pump, the nurse bases the response on which information about the pump?

4.It administers a small continuous dose of short-duration insulin subcutaneously. The client can self-administer an additional bolus dose from the pump before each meal. An insulin pump provides a small continuous dose of short-duration (rapid- or short-acting) insulin subcutaneously throughout the day and night. The client can self-administer an additional bolus dose from the pump before each meal as needed. Short-duration insulin is used in an insulin pump. An external pump is not attached surgically to the pancreas.

During health history taking, the client complains of weight loss and diarrhea and says that he can "feel my heart beating in my chest." The nurse anticipates that which diagnostic test will most likely be prescribed by the primary health care provider (PHCP) in order to determine the underlying condition leading to the client's signs and symptoms?

4.Serum thyroid-stimulating hormone (TSH) A client with increased activity of the thyroid gland exhibits weight loss as a result of the higher metabolic rate, increased frequency of bowel movements or diarrhea, and an increased pulse rate, which account for the client's complaint of feeling his heart beating in his chest. Therefore, a TSH level should be drawn to validate hyperthyroidism. The TSH level will be decreased in hyperthyroid states

During routine nursing assessment after hypophysectomy, a client complains of thirst and frequent urination. Knowing the expected complications of this surgery, what should the nurse assess next?

4.Urine specific gravity After hypophysectomy, temporary diabetes insipidus can result from antidiuretic hormone deficiency. This deficiency is related to surgical manipulation. The nurse should assess urine specific gravity and notify the primary health care provider if the result is less than 1.005. Although the remaining options may be components of the assessment, the nurse would next assess urine specific gravity.

A client is hospitalized with a diagnosis of adrenal insufficiency. Which findings does the nurse identify as supportive of this diagnosis? Select all that apply.

1,2,3,5 Findings consistent with a diagnosis of adrenal insufficiency include nausea, vomiting, and diarrhea; hyponatremia; salt craving; hyperkalemia; and orthostatic hypotension. Irritability and depression may also occur in primary adrenal hypofunction.

A nursing instructor is teaching the class about Addison's disease. The instructor determines that the class understands the disease process if they indicate which are affected in this disease? Select all that apply.

1,4,5 In Addison's disease, all three classes of corticosteroids are affected: glucocorticoids, mineralocorticoids, and androgens. Electrolytes and bicarbonate are not directly affected by Addison's disease.

The nurse is performing an assessment on a client with a diagnosis of myxedema (hypothyroidism). Which assessment finding should the nurse expect to note in this client?

1.Dry skin Myxedema is a deficiency of thyroid hormone. The client will present with a puffy, edematous face, especially around the eyes (periorbital edema), along with coarse facial features; dry skin; and dry, coarse hair and eyebrows. The remaining options are noted in the client with hyperthyroidism.

A client arrives in the hospital emergency department in an unconscious state. As reported by the spouse, the client has diabetes mellitus and began to show symptoms of hypoglycemia. A blood glucose level is obtained for the client, and the result is 40 mg/dL (2.28 mmol/L). Which medication should the nurse anticipate will be prescribed for the client?

1.Glucagon A blood glucose level lower than 50 mg/dL (2.85 mmol/L) is considered to be critically low. Glucagon is used to treat hypoglycemia because it increases blood glucose levels. Insulin would lower the client's blood glucose and would not be an appropriate treatment for hypoglycemia. Glyburide and metformin are oral hypoglycemic agents used to treat type 2 diabetes mellitus and would not be given to a client with hypoglycemia. In addition, an oral medication would not be administered to an unconscious client.

A client's serum blood glucose level is 48 mg/dL (2.74 mmol/L). The nurse would expect to note which as an additional finding when assessing this client?

1.Slurred speech A client who has a blood glucose level of less than 70 mg/dL (4 mmol/L) is considered to be hypoglycemic. A clinical manifestation of hypoglycemia is slurred speech.

A client with a diagnosis of diabetic ketoacidosis (DKA) is being treated in the emergency department. Which findings support this diagnosis? Select all that apply.

2,3,5 Because of the profound deficiency of insulin associated with DKA, glucose cannot be used for energy and the body breaks down fat as a secondary source of energy. Ketones, which are acid byproducts of fat metabolism, build up and the client experiences a metabolic ketoacidosis. High serum glucose contributes to an osmotic diuresis and the client becomes severely dehydrated. If untreated, the client will become comatose due to severe dehydration, acidosis, and electrolyte imbalance. Kussmaul's respirations, the deep rapid breathing associated with DKA, is a compensatory mechanism by the body. The body attempts to correct the acidotic state by blowing off carbon dioxide (CO2), which is an acid. In the absence of insulin, the client will experience severe hyperglycemia. Option 1 is incorrect because in acidosis the pH would be low. Option 4 is incorrect because a high serum glucose will result in an osmotic diuresis, and the client will experience polyuria.

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?

2.Calcium 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 taking a health history for a client with hyperparathyroidism. Which question would elicit information about this client's condition?

2."Are you experiencing pain in your joints?" Hyperparathyroidism is associated with oversecretion of parathyroid hormone (PTH), which causes excessive osteoblast growth and activity within the bones. When bone reabsorption is increased, calcium is released from the bones into the blood, causing hypercalcemia. The bones suffer demineralization as a result of calcium loss, leading to bone and joint pain and, sometimes, pathological fractures. Tremors and diarrhea relate to assessment findings of hypoparathyroidism. Swelling in the legs at night is unrelated to hyperparathyroidism

A client newly diagnosed with diabetes mellitus is instructed by the primary health care provider to obtain glucagon for emergency home use. The client asks a home care nurse about the purpose of the medication. What is the nurse's best response to the client's question?

2.4 oz of apple juice When a client is exhibiting symptoms of mild hypoglycemia, the nurse should provide the client with 15 g of a simple carbohydrate to quickly increase the blood glucose level. One half cup of apple juice is equivalent to 15 g of carbohydrates. The items in the remaining options do not provide a sufficient amount of carbohydrate.

A client has overactivity of the thyroid gland. The nurse should expect which finding?

2.Nutritional deficiencies Although the client may experience an increased appetite with overactivity of the thyroid gland, food intake does not meet energy demands, and nutritional deficiencies can develop. Weight loss occurs as a result of the increased metabolic activity. Glucose tolerance is decreased, and the client experiences hyperglycemia. Overactivity of the thyroid gland also causes increased metabolism, including fat metabolism. This leads to decreased levels of fat in the bloodstream, including cholesterol, and decreased body fat stores.

The nurse provides dietary instructions to a client with diabetes mellitus regarding the prescribed diet. Which statement, if made by the client, indicates a need for further teaching?

4."I need to purchase special dietetic foods." It is important to emphasize to the client and family that they are not eating a diabetic diet but rather a balanced meal plan. Adherence to nutritional 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.

A client with type 1 diabetes mellitus is having trouble remembering the types, duration, and onset of the action of insulin. The client tells the nurse that family members have not been supportive. Which response by the nurse is best?

4."Let me go over the types of insulins with you again." Reinforcement of knowledge and behaviors is vital to the success of the client's self-care. All of the other options do not address the need for client instructions and are not therapeutic responses.

The nurse is reviewing the primary health care provider's (PHCP's) prescriptions for a client with a diagnosis of diabetes mellitus who has been hospitalized for treatment of an infected foot ulcer. The nurse expects to note which finding in the PHCP's prescriptions?

4.An increased amount of NPH insulin daily insulin Infection is a physiological stressor that can cause an increase in the level of epinephrine in the body. An increase in epinephrine causes an increase in blood glucose levels. When the client is under stress, such as when an infection is present, an increase in the dose of insulin will be required to facilitate the transport of excess glucose into the cells. The client will not necessarily need an adjustment in the daily diet.

The nurse is monitoring a diabetic client with a blood glucose level of 400 mg/dL (22.2 mmol/L). Which clinical manifestation would indicate diabetic ketoacidosis (DKA)?

4.Rapid, deep respirations 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. This is because the body's compensatory response to the metabolic acidosis is to increase carbon dioxide (CO2) excretion by the lungs through deep, rapid breathing (Kussmaul respirations). Options 1, 2, and 3 are incorrect, as clients with DKA are dehydrated and thus have an increased heart rate and dry, scaly skin and do not have lower extremity edema.

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?

4.Severe abdominal pain 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 with suspected primary hyperparathyroidism is undergoing diagnostic testing. The nurse would assess for which as a manifestation of this disorder?

1.Polyuria Hypercalcemia classically occurs with hyperparathyroidism. Elevated serum calcium levels produce osmotic diuresis, making polyuria the correct option. The other manifestations listed are not associated with this disorder.

A client has been diagnosed with hyperthyroidism. The nurse monitors for which signs and symptoms indicating a complication of this disorder? Select all that apply.

1,2,4,5 Thyroid storm is an acute and life-threatening complication that occurs in a client with uncontrollable hyperthyroidism. Signs and symptoms of thyroid storm include elevated temperature (fever), nausea, and tremors. In addition, as the condition progresses, the client becomes confused. The client is restless and anxious and experiences tachycardia.

The nurse is caring for a client who has had an adrenalectomy and is monitoring the client for signs of adrenal insufficiency. Which signs and symptoms indicate adrenal insufficiency in this client?

1.Hypotension and fever The nurse should be alert to signs and symptoms of adrenal insufficiency after adrenalectomy. These signs and symptoms include weakness, hypotension, fever, and mental status changes. The remaining options are incorrect.

The nurse is admitting a client who is diagnosed with syndrome of inappropriate antidiuretic hormone secretion (SIADH) and has serum sodium of 118 mEq/L (118 mmol/L). Which prescriptions should the nurse anticipate receiving? Select all that apply.

1,3,5 Clients with SIADH experience excess secretion of antidiuretic hormone (ADH), which leads to excess intravascular volume, a declining serum osmolarity, and dilutional hyponatremia. Management is directed at correcting the hyponatremia and preventing cerebral edema. Hypertonic saline is prescribed when the hyponatremia is severe, less than 120 mEq/L (120 mmol/L). An intravenous (IV) infusion of 3% saline is hypertonic. Hypertonic saline must be infused slowly as prescribed, and an infusion pump must be used. Fluid restriction is a useful strategy aimed at correcting dilutional hyponatremia. Vasopressin is an ADH; vasopressin antagonists are used to treat SIADH. Furosemide may be used to treat extravascular volume and dilutional hyponatremia in SIADH, but it is only safe to use if the serum sodium is at least 125 mEq/L (125 mmol/L). When furosemide is used, potassium supplementation should also occur and serum potassium levels should be monitored. To promote venous return, the head of the bed should not be raised more than 10 degrees for the client with SIADH. Maximizing venous return helps to avoid stimulating stretch receptors in the heart that signal to the pituitary that more ADH is needed.

A client with diabetes mellitus who takes insulin is seen in the health care clinic. The client tells the clinic nurse that after the insulin injection, the insulin seems to leak through the skin. The nurse would appropriately determine the problem by asking the client which question?

1."Are you rotating the injection site?" The client should be instructed that insulin injection sites should be rotated within 1 anatomical area before moving on to another area. This rotation process promotes uniform absorption of insulin and reduces the chances of irritation. The remaining options are not associated with the condition (skin leakage of insulin) presented in the question.

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." 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 PHCP. 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 assessing a client who has a diagnosis of goiter. Which should the nurse expect to note during the assessment of the client?

1.An enlarged thyroid gland An enlarged thyroid gland develops in the client with goiter because of an excessive amount of thyroxine in the thyroid gland. Heart damage occurs with selenium deficiency. In addition, heart damage would not likely be noted during the nursing assessment. Further diagnostic tests in addition to the assessment would be necessary to determine heart damage. Chronic fatigue occurs with iron deficiency. Slow wound healing occurs with zinc deficiency.

A client received 5 units of insulin aspart subcutaneously just before eating lunch at 12:00 p.m. The nurse should assess the client for a hypoglycemic reaction at which times?

1.Between 1:00 and 3:00 p.m. Insulin aspart is a rapid-acting insulin. Its onset of action is 15 minutes; it peaks in 1 to 3 hours, and its duration of action is 3 to 5 hours. Hypoglycemic reactions are most likely to occur during peak time.

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 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.

During physical examination of a client, which finding is characteristic of hypothyroidism?

1.Periorbital edema Because cellular edema occurs in hypothyroidism, the client's appearance is changed. Nonpitting edema occurs, especially around the eyes and in the feet and hands. Knowing this should direct you to option 1. Flushed, warm skin; hyperactive bowel sounds; and tachycardia (heart rate >100 beats/min) are clinical manifestations of hyperthyroidism, which occurs as a result of excess thyroid hormone secretion, resulting in a hypermetabolic state.

A primary health care provider has prescribed propylthiouracil for a client with hyperthyroidism. The nurse recalls that first-line treatment calls for methimazole for medication therapy. The nurse should question the client about her past medical history, specifically regarding which condition?

1.Pregnancy Methimazole and propylthiouracil are both used to treat hyperthyroidism. Methimazole is considered first-line treatment; however, this medication cannot be used for clients who are in their first trimester of pregnancy, have had a previous adverse reaction to methimazole, or need rapid reduction of symptoms. Renal failure, prolonged QT interval, and adverse reaction to levothyroxine are not related to contraindications for methimazole.

A nurse notes that a client with type 1 diabetes mellitus has lipodystrophy on both upper thighs. The nurse should ask the client if which measure is taken?

1.Rotating sites for injection Lipodystrophy (hypertrophy of subcutaneous tissue at the injection site) occurs in some clients with diabetes mellitus when injection sites are used for a prolonged period. Therefore, clients are instructed to adhere to a plan of rotating injection sites to avoid tissue changes. Angle of insulin administration, cleansing with alcohol, and aspiration do not produce this complication.

A client with diabetes mellitus is being discharged following treatment for hyperosmolar hyperglycemic syndrome (HHS) precipitated by acute illness. The client tells the nurse, "I will call the primary health care provider (PHCP) the next time I can't eat for more than a day or so." Which statement reflects the most appropriate analysis of this client's level of knowledge?

1.The client needs immediate education before discharge. If the client becomes ill and cannot retain fluids or food for a period of 4 hours, the PHCP should be notified. The client's statement indicates a need for immediate education to prevent hyperosmolar hyperglycemic syndrome (HHS), a life-threatening emergency. Although all of the other options may be true, the most appropriate analysis is that the client requires immediate education.

A nurse is assigned to care for a client with type 1 diabetes mellitus. During the shift, the nurse should monitor for which manifestation as a sign of hypoglycemia?

1.Tremors Decreased blood glucose levels trigger autonomic nervous system signs and symptoms, such as nervousness, irritability, and tremors. Hot, dry skin accompanies hyperglycemia. Anorexia and muscle cramps are unrelated to hypoglycemia.

The nurse teaches a client with diabetes mellitus about differentiating between hypoglycemia and ketoacidosis. The client demonstrates an understanding of the teaching by stating that a form of glucose should be taken if which symptom or symptoms develop? Select all that apply.

2,3,5 Shakiness, palpitations, and lightheadedness are signs/symptoms of hypoglycemia and would indicate the need for food or glucose. Polyuria, blurred vision, and a fruity breath odor are manifestations of hyperglycemia.

A client is admitted to the hospital with a diagnosis of pheochromocytoma. The nurse would check which item to detect the primary manifestation of this disorder?

3.Blood pressure Hypertension is the major symptom associated with pheochromocytoma and is assessed by taking the client's blood pressure. Glycosuria, weight loss, and diaphoresis are other clinical manifestations of pheochromocytoma; however, hypertension is the major symptom.

The nurse has provided instructions to the client with hyperparathyroidism regarding home care measures to manage the symptoms of the disease. Which statement by the client indicates a need for further instruction?

2."I need to avoid doing any exercise at all." The client with hyperparathyroidism should pace activities throughout the day and plan for periods of uninterrupted rest. The client should plan for at least 30 minutes of walking each day to support calcium movement into the bones. The client should be instructed to avoid bed rest and use energy levels as a guide to activity. The client also should be instructed to avoid high-impact activity or contact sports.

The nurse is providing discharge instructions to a client who has Cushing's syndrome. Which client statement indicates that instructions related to dietary management are understood?

2."I should eat foods that have a lot of potassium in them." A diet low in carbohydrates and sodium but ample in protein and potassium is encouraged for a client with Cushing's syndrome. Such a diet promotes weight loss, reduction of edema and hypertension, control of hypokalemia, and rebuilding of wasted tissue

The nurse has provided home care measures to the client with diabetes mellitus regarding exercise and insulin administration. Which statement by the client indicates a need for further instruction?

2."I should perform my exercise at peak insulin time." The client should be instructed to avoid exercise at peak insulin time because this is when a hypoglycemic reaction is likely to occur. If exercises are performed at this time, the client should be instructed to eat an hour before the exercise and drink a carbohydrate liquid. The remaining options are correct statements regarding exercise, insulin, and diabetic control.

A client with type 1 diabetes mellitus who takes NPH daily in the morning 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?

2."The best time for me to exercise is after breakfast." Exercise is an important part of diabetes management. It promotes weight loss, decreases insulin resistance, and helps 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-g 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 primary 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. Option 4 is incorrect; NPH insulin is an intermediate-acting insulin, not a basal insulin.

Options 4 is incorrect; NPH insulin in an intermediate-acting insulin, not a basal insulin.

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?

2.Bulging eyeballs 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 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?

2.Convey empathy, trust, and respect toward the client. 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 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?

2.Monitor neck circumference every 4 hours. After thyroidectomy, neck circumference is monitored every 2 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 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?

2.Taking the client's blood pressure 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.

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?

2.Test the drainage for glucose. 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 nurse is reviewing the assessment findings and laboratory data for a client with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). The nurse understands that which symptoms are associated characteristics of this disorder? Select all that apply.

3,4,5,6 SIADH is characterized by inappropriate continued release of ADH. This results in water intoxication, manifested as fluid volume expansion, hypotonicity of body fluids, and hyponatremia as a result of the high urine osmolality and low serum osmolality.

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?

3."I need to avoid foods high in potassium." 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.

A nurse is providing home care instructions to a client with a diagnosis of Addison's disease. Which statement by the client indicates a need for further instruction?

3."I will need to take daily medications until my symptoms decrease. Client teaching includes the need for lifelong daily medications. The client also is instructed to carry or wear a medical identification card or bracelet. A travel kit will need to be purchased. It should contain oral cortisone along with intramuscular preparations for self-injection and intravenous vials for emergency injection by a primary health care provider. Increased glucocorticoid dosage during stressful minor illnesses will be necessary.

The nurse is performing an assessment on a client with pheochromocytoma. Which assessment data would indicate a potential complication associated with this disorder?

3.A heart rate that is 90 beats per minute and irregular Pheochromocytoma is a catecholamine-producing tumor usually found in the adrenal medulla, but extra-adrenal locations include the chest, bladder, abdomen, and brain; it is typically a benign tumor but can be malignant. Excessive amounts of epinephrine and norepinephrine are secreted. The complications associated with pheochromocytoma include hypertensive retinopathy and nephropathy, myocarditis, increased platelet aggregation, and stroke. Death can occur from shock, stroke, kidney failure, dysrhythmias, or dissecting aortic aneurysm. An irregular heart rate indicates the presence of a dysrhythmia. A coagulation time of 5 minutes is normal. A urinary output of 50 mL/hr is an adequate output. A blood urea nitrogen level of 20 mg/dL (7.1 mmol/L) is a normal finding.

The nurse is reviewing the laboratory test results for a client with a diagnosis of Cushing's syndrome. Which laboratory finding would the nurse expect to note in this client?

3.A potassium (K+) level of 5.5 mEq/L (5.5 mmol/L) The client with Cushing's syndrome experiences hyperkalemia, hyperglycemia, an elevated WBC count, and elevated plasma cortisol and adrenocorticotropic hormone levels. These abnormalities are caused by the effects of excess glucocorticoids and mineralocorticoids in the body. The laboratory values listed in the remaining options would not be noted in the client with Cushing's syndrome.

A client has been hospitalized for impaired function of the posterior pituitary gland. The nurse plans to monitor for signs and symptoms of which hormone imbalance?

3.Antidiuretic hormone (ADH) ADH is secreted by the posterior pituitary gland. The other hormone stored in the posterior pituitary gland is oxytocin. Both ADH and oxytocin are synthesized by the hypothalamus and stored in the posterior pituitary gland. These hormones are released as needed into the bloodstream. The anterior pituitary gland produces GH, LH, and FSH.

The nurse is reviewing the postoperative prescriptions for a client who had a transsphenoidal hypophysectomy. Which prescription, if noted on the record, would indicate the need for clarification?

3.Apply a loose dressing if any clear drainage is noted. 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 surgeon needs to be notified. Therefore, clarification is needed regarding application of a loose dressing. The remaining options indicate appropriate postoperative interventions.

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?

3.Decreased serum calcium level 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.

A client has been diagnosed with pheochromocytoma. Which clinical manifestation is most indicative of this condition?

3.Hypertension 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 admitted to the hospital with uncontrolled type 1 diabetes mellitus. In the event that diabetic ketoacidosis (DKA) does occur, the nurse anticipates that which medication would most likely be prescribed?

3.Regular insulin Giving regular insulin by the intravenous route is the treatment of choice for DKA. A short-acting insulin is the only insulin that can be given intravenously because it can be titrated to the client's blood glucose levels. Glucagon is used to treat hypoglycemia because it increases blood glucose levels, and glyburide is an oral hypoglycemic agent used to treat type 2 diabetes mellitus; both agents are inappropriate. NPH insulin is an intermediate-acting insulin and therefore is not appropriate for treatment of DKA.

The nurse is caring for a client scheduled for a transsphenoidal hypophysectomy. The preoperative teaching instructions should include which statement?

4."Brushing your teeth needs to be avoided for at least 2 weeks after surgery A transsphenoidal hypophysectomy is a surgical approach that uses the nasal sinuses and nose for access to the pituitary gland. Based on the location of the surgical procedure, spinal anesthesia would not be used. In addition, the hair would not be shaved. Although ambulating is important, specific to this procedure is avoiding brushing the teeth to prevent disruption of the surgical site.

The nurse has provided instructions for measuring blood glucose levels to a client newly diagnosed with diabetes mellitus who will be taking insulin. The client demonstrates understanding of the instructions by identifying which method as the best method for monitoring blood glucose levels?

4."I will check my blood glucose level before each meal and at bedtime." The most effective and accurate measure for testing blood glucose is to test the level before each meal and at bedtime. If possible and feasible, testing should be done during the nighttime hours. Checking the level after the meal will provide an inaccurate assessment of diabetes control. Checking the level once daily will not provide enough data to control the diabetes mellitus.

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?

4."My body increases glucagon production to fight low blood sugars." 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 nurse is assisting a client with diabetes mellitus who is recovering from diabetic ketoacidosis (DKA) to develop a plan to prevent a recurrence. Which is most important to include in the plan of care?

Client education after DKA should emphasize the need for home glucose monitoring 2 to 4 times per day. Instructing the client to notify the primary health care provider when illness occurs is also important. The presence of urine ketones indicates that DKA has occurred already. The client should eat well-balanced meals with snacks as prescribed.
