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."

ANS: 1 "I need to stop my insulin." Rationale: 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 administers vasopressin to a client and recalls that the medication is which type of hormone? 1. Growth hormone 2. Luteinizing hormone 3. Antidiuretic hormone 4. Thyroid-stimulating hormone

ANS: 3 Rationale: Vasopressin is an antidiuretic hormone. Somatotropin is a growth hormone. Gonadotropin is a luteinizing hormone. Thyrotropin is a thyroid-stimulating hormone.

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

ANS: 4 Rationale: 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 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 2. Diaphoresis 3. Pedal edema 4. Decreased respiratory rate

ANS: 1 Polyuria Rationale: 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 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 2. Glyburide 3. Metformin 4. Regular insulin

ANS: 1 Rationale: 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.

Which adverse effect can be seen in a female client with gonadotropin deficiency and who is undergoing hormone replacement therapy? 1. Thrombosis 2. Hypotension 3. Dehydration 4. Increased thirst

ANS: 1 Rationale: A female client with gonadotropin deficiency is treated by replacement therapy of combined hormones, namely estrogen and progesterone. The side effect of this therapy is the increased risk of thrombosis or formation of blood clots in deep veins. Hypertension is a side effect of estrogen-progesterone therapy, not hypotension. Dehydration and increased thirst could indicate vasopressin deficiency.

The nurse would observe a client for which side effect when administering androgen therapy? 1. Baldness 2. Headaches 3. Gastric irritation 4. Orthostatic hypotension

ANS: 1 Rationale: Androgen therapy may cause baldness, gynecomastia, and acne. Headaches, gastric irritation, and orthostatic hypotension are associated with bromocriptine, which is used to treat hyperpituitarism.

Why is blood glucose self-monitoring preferred over urine glucose testing? 1. Blood glucose monitoring is more accurate. 2. Blood glucose monitoring is easier to perform. 3. Blood glucose monitoring is done by the client. 4. Blood glucose monitoring is not influenced by medications.

ANS: 1 Rationale: Blood glucose testing is a more direct and accurate measure; urine testing provides an indirect measure that can be influenced by kidney function and the amount of time the urine is retained in the bladder. Whereas blood and urine testing is relatively simple, testing the blood involves additional knowledge. Both procedures can be done by the client. Whether or not it is influenced by medications is not a factor. Although some urine tests are influenced by medications, there are methods to test urine to bypass this effect.

Which clinical manifestation is seen in a male client as a result of deficiency of gonadotropin? 1. Decreased fertility 2. Increased muscle mass 3. Increased bone density 4. Decreased urine specific gravity

ANS: 1 Rationale: Deficiency of gonadotropin in males results in clinical manifestation of infertility because of impotence. There is loss of muscle mass and bone density because of gonadotropin deficiency. Clients with diabetes insipidus have decreased urine specific gravity, usually less than 1.005.

Which skin condition would the nurse expect when performing a physical assessment on a client with a history of hypothyroidism? 1. Dry 2. Moist 3. Flushed 4. Smooth

ANS: 1 Rationale: Dry skin is caused by decreased function of sebaceous glands; a paucity of thyroid hormones T3 and T4, which control the basal metabolic rate, can alter the function of almost every body system. The skin will not be flushed; the client will appear pale. Moist, smooth skin occurs with hyperfunction of the thyroid and an increase in the basal metabolic rate.

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 health care provider (HCP) 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. 2. The client requires follow-up teaching regarding the administration of oral antidiabetics. 3. The client's statement is inaccurate, and he or she should be scheduled for outpatient diabetic counseling. 4. The client's statement is inaccurate, and he or she should be scheduled for educational home health visits.

ANS: 1 Rationale: If the client becomes ill and cannot retain fluids or food for a period of 4 hours, the HCP 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.

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 limit my fluids to 1 liter per day." 2. "I should use my treadmill or go for walks daily." 3. "I should follow a moderate-calcium, high-fiber diet." 4. "My alendronate helps to keep calcium from coming out of my bones."

ANS: 1 Rationale: 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 2 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 to protect against pathological fracture. Walking, as an exercise, should be encouraged in the client with hyperparathyroidism. Clients should follow a moderate-calcium, high-fiber diet. 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 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.

ANS: 1 Rationale: 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 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 2. Thin, silky hair 3. Bulging eyeballs 4. Fine muscle tremors

ANS: 1 Rationale: 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.

Which hormone is released from the posterior pituitary gland? 1. Oxytocin 2. Prolactin 3. Growth hormone 4. Luteinizing hormone

ANS: 1 Rationale: Oxytocin is released from the posterior pituitary gland, which acts on the uterus and mammary glands. Prolactin, growth hormone, and luteinizing hormone are produced by the anterior pituitary gland.

Which hormone has both inhibiting and releasing action? 1. Prolactin 2. Somatostatin 3. Somatotropin 4. Gonadotropin

ANS: 1 Rationale: Prolactin secreted by the hypothalamus has both inhibiting and releasing action. Somatostatin inhibits the secretion of growth hormone. Somatotropin and gonadotropin are releasing hormones.

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?" 2. "Are you aspirating before you inject the insulin?" 3. "Are you using a 1-inch needle to give the injection?" 4. "Are you placing an air bubble in the syringe before injection?"

ANS: 1 Rationale: 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 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 2. Mental status changes and hypertension 3. Subnormal temperature and hypotension 4. Complaints of weakness and hypertension

ANS: 1 Rationale: 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.

A client reports their lips feel thicker, and they have joint pain and coarse facial features. The nurse would suspect an excessive secretion of which hormone? 1. Growth hormone 2. Prolactin hormone 3. Thyroid-stimulating hormone 4. Adrenocorticotropic hormone

ANS: 1 Rationale: Thickened lips, joint pain, and coarse facial features are the symptoms of acromegaly, which is caused by pituitary gland hyperfunction leading to excessive secretion of growth hormone. Prolactin hormone hypersecretion can cause hypogonadism, which is loss of sexual characteristics. Thyroid-stimulating hormone hypersecretion can result in increases in both plasma thyroid-stimulating hormone and thyroid hormone levels. Adrenocorticotropic hormone hypersecretion can cause Cushing disease characterized by increased plasma cortisol levels.

The nurse is monitoring a client with Graves' disease for signs of thyrotoxic crisis (thyroid storm). Which signs or symptoms, if noted in the client, will alert the nurse to the presence of this crisis? 1. Fever and tachycardia 2. Pallor and tachycardia 3. Agitation and bradycardia 4. Restlessness and bradycardia

ANS: 1 Rationale: Thyrotoxic crisis (thyroid storm) is an acute, potentially life-threatening state of extreme thyroid activity that represents a breakdown in the body's tolerance to a chronic excess of thyroid hormones. The clinical manifestations include fever with temperatures greater than 100°F, severe tachycardia, flushing and sweating, and marked agitation and restlessness. Delirium and coma can occur.

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

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

The nurse is educating a client about managing hypoglycemia unawareness. Which information would the nurse provide? 1. Refrain from alternative testing sites. 2. Use any available meter to monitor levels. 3. Initiate continuous blood glucose monitoring. 4. Calibrate the meter before managing hypoglycemia.

ANS: 1 Rationale: When the client is managing hypoglycemia, the same site should be used to obtain blood glucose levels. This provides consistent readings because blood glucose levels are changing rapidly. The client should use his or her meter to monitor blood glucose levels for consistency. Continuous blood glucose monitoring should be implemented when the client is stable, not during hypoglycemic episodes. The client should calibrate the meter once a day, but not when hypoglycemic. The client needs a meter that can provide instant results without waiting for tests to be performed on the meter itself.

Which hormones are most commonly produced in excess with hyperpituitarism? Select all that apply. 1. Prolactin 2. Growth hormone 3. Luteinizing hormone 4. Antidiuretic hormone 5. Melanocyte-stimulating hormone

ANS: 1, 2 Rationale: The most common hormones produced in excess with hyperpituitarism are prolactin and growth hormone. Excessive stimulation of luteinizing hormone and antidiuretic hormone is also associated with hyperpituitarism, but less commonly than prolactin and growth hormone. Secretion of melanocyte-stimulating hormone stimulates adrenocorticotropic hormone, which indirectly stimulates the pituitary gland, thus leading to hyperpituitarism.

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. Monitor daily weight. 2. Monitor intake and output. 3. Assess extremities for edema. 4. Maintain a high-sodium diet. 5. Maintain a low-potassium diet.

ANS: 1, 2, 3 Rationale: 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.

Which glands secrete hormones that regulate metabolism of carbohydrates, proteins, and fats? Select all that apply. 1. Pancreas 2. Thyroid gland 3. Adrenal cortex 4. Adrenal medulla 5. Parathyroid gland

ANS: 1, 2, 3 Rationale: The pancreas secretes insulin and glucagon, which affects the body's metabolism of carbohydrates, proteins, and fats. The thyroid gland secretes thyroid hormones T3 and T4 that regulate carbohydrates, proteins, and fat metabolism. Cortisol is a glucocorticoid secreted by the adrenal cortex that affects carbohydrates, proteins, and fat metabolism. Adrenal medulla secretes catecholamines, which do not affect metabolism of carbohydrates, proteins, and fats. Hormones secreted by the parathyroid gland mainly regulate calcium and phosphorus metabolism.

The nurse is providing home care instructions to the client with a diagnosis of Cushing's syndrome and prepares a list of instructions for the client. Which instructions should be included on the list? Select all that apply. 1. The signs and symptoms of hypoadrenalism 2. The signs and symptoms of hyperadrenalism 3. Instructions to take the medications exactly as prescribed 4. The importance of maintaining regular outpatient follow-up care 5. A reminder to read the labels on over-the-counter medications before purchase

ANS: 1, 2, 3, 4 Rationale: The client with Cushing's syndrome should be instructed to take the medications exactly as prescribed. The nurse should emphasize the importance of continuing medications, consulting with the health care provider (HCP) before purchasing any over-the-counter medications, and maintaining regular outpatient follow-up care. The nurse also should instruct the client in the signs and symptoms of both hypoadrenalism and hyperadrenalism.

A nurse is reviewing the assessment findings for a client who was admitted to the hospital with a diagnosis of diabetes insipidus. The nurse understands that which manifestations are associated with this disorder? Select all that apply. 1. Polyuria 2. Polydipsia 3. Concentrated urine 4. Complaints of excessive thirst 5. Specific gravity lower than 1.005

ANS: 1, 2, 4, 5 Rationale: A triad of clinical symptoms-polyuria, polydipsia, and excessive thirst-often occurs suddenly in the client with diabetes insipidus. The urine is dilute, with a specific gravity lower than 1.005, and the urine osmolality is low (50 to 200 mOsm/L).

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. Fever 2. Nausea 3. Lethargy 4. Tremors 5. Confusion 6. Bradycardia

ANS: 1, 2, 4, 5 Rationale: 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.

Identify the primary causes of adrenal insufficiency. Select all that apply. 1. Hemorrhage 2. Tuberculosis 3. Pituitary tumors 4. Postpartum pituitary necrosis 5. Acquired immunodeficiency syndrome (AIDS)

ANS: 1, 2, 5 Rationale: The primary causes of adrenal insufficiency are hemorrhage, tuberculosis, and AIDS. Pituitary tumors and postpartum pituitary necrosis are the secondary cases of adrenal insufficiency.

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. Hypotension 2. Leukocytosis 3. Hyperkalemia 4. Hypercalcemia 5. Hypernatremia

ANS: 1, 3 Rationale: 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. Polyuria 2. Headache 3. Bone pain 4. Nervousness 5. Weight gain

ANS: 1, 3 Rationale: 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. Tremors 2. Anorexia 3. Irritability 4. Nervousness 5. Hot, dry skin 6. Muscle cramps

ANS: 1, 3, 4 Rationale: 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.

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 health care provider prescriptions should the nurse anticipate receiving? Select all that apply. 1. Initiate an infusion of 3% NaCl. 2. Administer intravenous furosemide. 3. Restrict fluids to 800 mL over 24 hours. 4. Elevate the head of the bed to high Fowler's. 5. Administer a vasopressin antagonist as prescribed.

ANS: 1, 3, 5 Rationale: 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.

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? Select all that apply. 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.

ANS: 1, 4, 5 Rationale: 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 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.

ANS: 2 Convey empathy, trust, and respect toward the client. Rationale: 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 is preparing a plan of care for a client with diabetes mellitus who has hyperglycemia. The nurse places priority on which client problem? 1. Lack of knowledge 2. Inadequate fluid volume 3. Compromised family coping 4. Inadequate consumption of nutrients

ANS: 2 Inadequate fluid volume Rationale: HomeHistoryHelpCalculator Study Mode Question 9 of 175 QN: 553 | ID: 553 | file: 0545-0569 PreviousGoNextStopBookmarkRationaleStrategyReference(s)Submit 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? Rationale: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.

When obtaining a health history from a client recently diagnosed with type 1 diabetes, the nurse expects the client to report which clinical manifestation? 1. Nervousness 2. Polyuria 3. Nocturia 4. Diaphoresis

ANS: 2 Polyuria Rationale: Excessive thirst (polydipsia), excessive hunger (polyphagia), and frequent urination (polyuria) are caused by the body's inability to metabolize glucose adequately. Lethargy, not nervousness, occurs because of a lack of metabolized glucose for energy. Frequent urination occurs throughout a 24-hour period because glucose in the urine pulls fluid with it. Diaphoresis occurs with severe hypoglycemia, not hyperglycemia.

Which is a secondary cause of adrenal insufficiency? 1. Hemorrhage 2. Tuberculosis 3. Pituitary tumors 4. Metastatic cancer

ANS: 3 Rationale: Adrenal insufficiency is also called Addison disease. Secondary causes of adrenal insufficiency include pituitary tumors. Primary causes, which are responsible for adrenal insufficiency, include hemorrhage, tuberculosis, and metastatic cancer.

The nurse in a health care clinic is reviewing the record of a client with diabetes mellitus who was just seen by the health care provider (HCP). The nurse notes that the HCP has prescribed acarbose. Which preexisting disorder, if noted in the client's record, would indicate a contraindication to the use of this medication? 1. Hypothyroidism 2. Renal insufficiency 3. Arterial insufficiency 4. Coronary artery disease

ANS: 2 Rationale: Acarbose is an antidiabetic medication that may be administered alone or in conjunction with another antidiabetic medication. It is contraindicated in clients with significant renal dysfunction. It also is contraindicated in clients with inflammatory bowel disease, colonic ulceration, or partial intestinal obstruction.

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.

ANS: 2 Rationale: 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.

Which hormone is formed from cholesterol? 1. Insulin 2. Cortisol 3. Prolactin 4. Growth hormone

ANS: 2 Rationale: All lipid-soluble hormones are synthesized from cholesterol. Cortisol, a lipid-soluble hormone, is secreted by the adrenal cortex. All water-soluble hormones are formed from amino acids. Insulin, prolactin, and growth hormone are water-soluble hormones. Insulin is secreted by the pancreas. Prolactin and growth hormone are also secreted by the pituitary gland.

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."

ANS: 2 Rationale: 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.

The nurse cares for a client with an abnormal cortisol level. The nurse recalls which information about cortisol? 1. Cortisol metabolizes free fatty acids. 2. Cortisol stimulates gluconeogenesis. 3. Cortisol stimulates protein synthesis. 4. Cortisol levels decline in stressful conditions.

ANS: 2 Rationale: Cortisol maintains the blood glucose concentration by stimulating the liver for gluconeogenesis. Gluconeogenesis involves formation of glucose from amino acids and fatty acids. Cortisol mobilizes free fatty acids and inhibits protein synthesis. The blood levels of cortisol increase in stressful conditions.

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."

ANS: 2 Rationale: 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.

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

ANS: 2 Rationale: 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.

The nurse caring for a client with a diagnosis of hypoparathyroidism reviews the laboratory results of blood tests for this client and notes that the calcium level is extremely low. The nurse should expect to note which finding on assessment of the client? 1. Unresponsive pupils 2. Positive Trousseau's sign 3. Negative Chvostek's sign 4. Hypoactive bowel sounds

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

Which clinical manifestation would be expected in a client with hyposecretion of growth hormone? 1. Lethargy 2. Weight gain 3. Decreased libido 4. Reduced bone density

ANS: 4 Rationale: Growth hormone deficiency changes tissue growth patterns, resulting in increasing bone destructive activity and reduced bone density. A client becomes lethargic and gains weight because of the deficiency of thyroid-stimulating hormone. Decreased libido (sexual desire) occurs as a result of the deficiency of gonadotropins.

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.

ANS: 2 Rationale: 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.

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

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

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? 1. "I should always wear a MedicAlert bracelet." 2. "I should perform my exercise at peak insulin time." 3. "I should always carry a quick-acting carbohydrate when I exercise." 4. "I should avoid exercising at times when a hypoglycemic reaction is likely to occur."

ANS: 2 Rationale: 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 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."

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

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? 1. "I should avoid bed rest." 2. "I need to avoid doing any exercise at all." 3. "I need to space activity throughout the day." 4. "I should gauge my activity level by my energy level."

ANS: 2 Rationale: 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.

A client has been hospitalized for an endocrine system dysfunction of the pancreas. The registered nurse asks the new orientee nurse what kind of problem a client hospitalized for endocrine dysfunction of the pancreas would expect. The new orientee nurse demonstrates understanding if which statement is made? 1. "Lipase levels will decrease." 2. "Insulin production will be decreased." 3. "There will be overproduction of trypsin." 4. "Amylase will be secreted in excess amounts."

ANS: 2 Rationale: The pancreas produces both endocrine and exocrine secretions as part of its normal function. The organ secretes insulin as a key endocrine hormone to regulate the blood glucose level. When there is endocrine dysfunction, insulin production is affected due to damage to beta cells. Other pancreatic endocrine hormones are glucagon and somatostatin. The exocrine pancreas produces digestive enzymes such as amylase, lipase, and trypsin.

To ensure a quality specimen and an accurate test result, which instruction would the nurse give a client who is scheduled to undergo urine endocrine testing? 1. "Start the urine collection when the bladder is full." 2. "Store the urine specimen in a cooler with ice." 3. "Store the urine specimen in a home refrigerator." 4. "Save the urine specimen that begins the collection."

ANS: 2 Rationale: The urine specimen that is collected for endocrine testing should be stored in a cooler with ice to prevent bacterial growth in the specimen. The nurse should instruct the client to start the urine collection after emptying the bladder. The client should be instructed not to store the urine specimen in a home refrigerator with other food and drinks because it could lead to cross-contamination. The client should be instructed to refrain from saving the urine specimen that begins the collection because the timing for urine collection starts from after the initial voiding specimen.

The nursing instructor asks a nursing student to identify the risk factors associated with the development of thyrotoxicosis. The student demonstrates understanding of the risk factors by identifying an increased risk for thyrotoxicosis in which client? 1. A client with hypothyroidism 2. A client with Graves' disease who is having surgery 3. A client with diabetes mellitus scheduled for a diagnostic test 4. A client with diabetes mellitus scheduled for debridement of a foot ulcer

ANS: 2 Rationale: Thyrotoxicosis usually is seen in clients with Graves' disease in whom the symptoms are precipitated by a major stressor. This complication typically occurs during periods of severe physiological or psychological stress such as trauma, sepsis, delivery, or major surgery. It also must be recognized as a potential complication after thyroidectomy. The client conditions in the remaining options are not associated with thyrotoxicosis.

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? 1. Growth hormone (GH) 2. Luteinizing hormone (LH) 3. Antidiuretic hormone (ADH) 4. Follicle-stimulating hormone (FSH)

ANS: 3 Rationale: 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 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.

ANS: 2 Test the drainage for glucose. Rationale: 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.

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. 1. Polyuria 2. Shakiness 3. Palpitations 4. Blurred vision 5. Lightheadedness 6. Fruity breath order

ANS: 2, 3, 5

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. 1. Increase in pH 2. Comatose state 3. Deep, rapid breathing 4. Decreased urine output 5. Elevated blood glucose level.

ANS: 2, 3, 5 Rationale: 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.

The nurse is monitoring a client diagnosed with acromegaly who was treated with transsphenoidal hypophysectomy and is recovering in the intensive care unit. Which findings should alert the nurse to the presence of a possible postoperative complication? Select all that apply. 1. Anxiety 2. Leukocytosis 3. Chvostek's sign 4. Urinary output of 800 mL/hour 5. Clear drainage on nasal dripper pad

ANS: 2, 4, 5 Rationale: Acromegaly results from excess secretion of growth hormone, usually caused by a benign tumor on the anterior pituitary gland. Treatment is surgical removal of the tumor, usually with a sublingual transsphenoidal complete or partial hypophysectomy. The sublingual transsphenoidal approach is often through an incision in the inner upper lip at the gum line. Transsphenoidal surgery is a type of brain surgery and infection is a primary concern. Leukocytosis, or an elevated white count, may indicate infection. Diabetes insipidus is a possible complication of transsphenoidal hypophysectomy. In diabetes insipidus there is decreased secretion of antidiuretic hormone and clients excrete large amounts of dilute urine. Following transsphenoidal surgery, the nasal passages are packed and a dripper pad is secured under the nares. Clear drainage on the dripper pad is suggestive of a cerebrospinal fluid leak. The surgeon should be notified and the drainage should be tested for glucose. A cerebrospinal fluid leak increases the postoperative risk of meningitis. Anxiety is a nonspecific finding that is common to many disorders. Chvostek's sign is a test of nerve hyperexcitability associated with hypocalcemia and is seen as grimacing in response to tapping on the facial nerve. Chvostek's sign has no association with complications of sublingual transsphenoidal hypophysectomy.

Which term would the nurse use in a report to describe the absence of menstrual periods in a 35-year-old nonpregnant client? 1. Rhinorrhea 2. Menopause 3. Amenorrhea 4. Dyspareunia

ANS: 3 Amenorrhea Rationale: The absence of menstrual periods in a nonpregnant client younger than 55 years old is called amenorrhea. Rhinorrhea is an allergic state that is manifested by a runny nose. Menopause is cessation of menstruation after 55 years of age. Dyspareunia is pain during sexual intercourse.

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? 1. An ampule of 50% dextrose 2. NPH insulin subcutaneously 3. IV fluids containing dextrose 4. Phenytoin for the prevention of seizures

ANS: 3 IV fluids containing dextrose Rationale: 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 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

ANS: 3 Intravenous infusion of normal saline. Rationale: 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 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

ANS: 3 Rationale: 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 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? 1. "I need to wear a MedicAlert bracelet." 2. "I need to purchase a travel kit that contains cortisone." 3. "I will need to take daily medications until my symptoms decrease." 4. "I need an increased dose of glucocorticoid medication during stressful minor illnesses."

ANS: 3 Rationale: 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 health care provider. Increased glucocorticoid dosage during stressful minor illnesses will be necessary.

A client newly diagnosed with type 1 diabetes asks why it is necessary to exercise on a regular basis. Which response is accurate? 1. "Exercise decreases insulin sensitivity." 2. "It stimulates glucagon production." 3. "Exercise improves the cellular uptake of glucose." 4. "It reduces metabolic requirements for glucose."

ANS: 3 Rationale: Exercise increases the metabolic rate, and glucose is needed for cellular metabolism; therefore, excess glucose is consumed during exercise. Regular vigorous exercise increases cell sensitivity to insulin. Glucagon action raises blood glucose but does not affect cell uptake or use of glucose. Cellular requirements for glucose increase with exercise.

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? 1. Glucagon 2. Glyburide 3. Regular insulin 4. Neutral protamine Hagedorn (NPH) insulin

ANS: 3 Rationale: 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.

Which symptom would the nurse identify when assessing a client with Graves disease? 1. Constipation 2. Lethargy 3. Exophthalmos 4. Weight gain

ANS: 3 Rationale: Graves disease is a common cause of hyperthyroidism. Exophthalmos occurs because of peribulbar edema in hyperthyroidism. Constipation, lethargy, weight gain are all associated with hypothyroidism because of the decreased metabolic rate.

The nurse is caring for a client after thyroidectomy. The client expresses concern about the postoperative voice hoarseness she is experiencing and asks if the hoarseness will subside. The nurse should provide the client with which information? 1. It indicates nerve damage. 2. The hoarseness is permanent. 3. It is normal during this time and will subside. 4. It will worsen before it subsides, which may take 6 months.

ANS: 3 Rationale: Hoarseness in the postoperative period usually is the result of laryngeal pressure or edema and will resolve within a few days. The client should be reassured that the effects are transitory. The other options are incorrect.

The emergency department nurse is preparing a plan for initial care of a client with a diagnosis of hyperosmolar hyperglycemic syndrome (HHS). The nurse recognizes that the hyperglycemia associated with this disorder results from which occurrence? 1. Increased use of glucose 2. Overproduction of insulin 3. Increased production of glucose 4. Increased osmotic movement of water

ANS: 3 Rationale: Hyperglycemia results from decreased use and increased production of glucose. Increased use of glucose and overproduction of insulin would most likely cause hypoglycemia. Option 4 is incorrect.

The nurse is caring for a client after thyroidectomy. The nurse notes that calcium gluconate is prescribed for the client. The nurse determines that this medication has been prescribed for which purpose? 1. To treat thyroid storm 2. To prevent cardiac irritability 3. To treat hypocalcemic tetany 4. To stimulate release of parathyroid hormone

ANS: 3 Rationale: Hypocalcemia, resulting in tetany, can develop after thyroidectomy if the parathyroid glands are accidentally removed during surgery. Manifestations develop 1 to 7 days after surgery. If the client develops numbness and tingling around the mouth, fingertips, or toes; muscle spasms; or twitching, the health care provider is notified immediately. Calcium gluconate should be readily available in the nursing unit.

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

ANS: 3 Rationale: 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 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."

ANS: 3 Rationale: 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.

The nurse is performing an assessment on a client with pheochromocytoma. Which assessment data would indicate a potential complication associated with this disorder? 1. A urinary output of 50 mL/hour 2. A coagulation time of 5 minutes 3. A heart rate that is 90 beats/minute and irregular 4. A blood urea nitrogen level of 20 mg/dL

ANS: 3 Rationale: Pheochromocytoma is a catecholamine-producing tumor usually found in the adrenal medulla, but extraadrenal 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.

The nurse is monitoring a client with diabetes mellitus for signs of hypoglycemia. Which manifestations are associated with this complication? 1. Slow pulse; lethargy; warm, dry skin 2. Elevated pulse; lethargy; warm, dry skin 3. Elevated pulse; shakiness; cool, clammy skin 4. Slow pulse, confusion, increased urine output

ANS: 3 Rationale: Signs and symptoms of mild hypoglycemia include tachycardia; shakiness; and cool, clammy skin. The remaining options do not specify the manifestations of hypoglycemia.

Which intervention would the nurse implement for a client who has type 1 diabetes and has an elevated blood glucose? 1. Administer an oral hypoglycemic 2. Institute urine glucose monitoring 3. Give supplemental doses of regular insulin 4. Decrease the rate of the intravenous infusion.

ANS: 3 Rationale: The blood glucose level needs to be reduced; regular insulin begins to act in 30 to 60 minutes. The client has type 1, not type 2, diabetes, and an oral hypoglycemic will not be effective. Blood glucose levels are far more accurate than urine glucose levels. The rate may be increased because polyuria often accompanies hyperglycemia.

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? 1. A platelet of 200,000 mm3 (200 × 109/L) 2. A blood glucose level of 110 mg/dL (6.28 mmol/L) 3. A potassium (K+) level of 3.0 mEq/L (3.0 mmol/L) 4. A white blood cell (WBC) count of 6000 mm3 (6 × 109/L)

ANS: 3 Rationale: The client with Cushing's syndrome experiences hypokalemia, 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.

The nurse has provided dietary instructions to a client with a diagnosis of hypoparathyroidism. The nurse should instruct the client that it is acceptable to include which item in the diet? 1. Fish 2. Cereals 3. Vegetables 4. Meat and poultry

ANS: 3 Rationale: The client with hypoparathyroidism is instructed to follow a calcium-rich diet and to restrict the amount of phosphorus in the diet. Vegetables are allowed in the diet. The client should limit meat, poultry, fish, eggs, cheese, and cereals.

A nurse educator instructs a new nurse during orientation about the physiological processes of the endocrine system. Which statement made by the new nurse indicates effective learning? 1. "The endocrine system comprises glands with narrow ducts." 2. "The endocrine system comprises salivary and lacrimal glands." 3. "The hormones of the endocrine system exert their action by 'lock and key' mechanism." 4. "The hormones secreted by endocrine system exert their action on all tissues they contact."

ANS: 3 Rationale: The endocrine glands secrete hormones that exert their action on the target tissues by the "lock and key" mechanism. The hormones recognize and adhere only to specific receptor sites on the target tissue, like a correct key alone can open its specific lock. The glands of the endocrine system are ductless and secrete hormones that are carried via the blood circulation. Salivary and lacrimal glands are not endocrine but secretory glands. The hormones are carried via blood to various tissues, but they exert their action only on specific target tissues.

The nurse is providing instructions regarding insulin administration for a client newly diagnosed with diabetes mellitus. The health care provider has prescribed a mixture of NPH insulin and regular insulin. The nurse should instruct the client that which is the first step in this procedure? 1. Draw up the correct dosage of NPH insulin into the syringe. 2. Draw up the correct dosage of regular insulin into the syringe. 3. Inject air equal to the amount of NPH insulin prescribed into the vial of NPH insulin. 4. Inject air equal to the amount of regular insulin prescribed into the vial of regular insulin.

ANS: 3 Rationale: The initial step in preparing an injection of insulin that is a mixture of NPH and regular insulin is to inject air into the NPH insulin bottle equal to the amount of insulin prescribed. The client would then be instructed to inject an amount of air equal to the amount of prescribed insulin into the regular insulin bottle. The regular insulin would then be withdrawn, followed by the NPH insulin. Contamination of regular insulin with NPH insulin will convert part of the regular insulin into a longer acting form.

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.

ANS: 3 Rationale: 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.

A client has just been admitted to the nursing unit following thyroidectomy. Which assessment is the priority for this client? 1. Hypoglycemia 2. Level of hoarseness 3. Respiratory distress 4. Edema at the surgical site

ANS: 3 Rationale: 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 should include which interventions in the plan of care for a client with hyperthyroidism? Select all that apply. 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.

ANS: 3, 4 Rationale: 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.

The nurse is preparing a client with a new diagnosis of hypothyroidism for discharge. The nurse determines that the client understands discharge instructions if the client states that which signs and symptoms are associated with this diagnosis? Select all that apply. 1. Tremors 2. Weight loss 3. Feeling cold 4. Loss of body hair 5. Persistent lethargy 6. Puffiness of the face

ANS: 3, 4, 5, 6 Rationale: Feeling cold, hair loss, lethargy, and facial puffiness are signs of hypothyroidism. Tremors and weight loss are signs of hyperthyroidism.

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. 1. Hypernatremia 2. Signs of water deficit 3. High urine osmolality 4. Low serum osmolality 5. Hypotonicity of body fluids 6. Continued release of antidiuretic hormone (ADH)

ANS: 3, 4, 5, 6 Rationale: 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 should include which interventions in the plan of care for a client with hypothyroidism? Select all that apply. 1. Provide a cool environment for the client. 2. Instruct the client to consume a high-fat diet. 3. Instruct the client about thyroid replacement therapy. 4. Encourage the client to consume fluids and high-fiber foods in the diet. 5. Inform the client that iodine preparations will be prescribed to treat the disorder. 6. Instruct the client to contact the health care provider (HCP) if episodes of chest pain occur.

ANS: 3, 4, 6 Rationale: 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 HCP if chest pain occurs because it could be an indication of overreplacement of thyroid hormone.

The nurse provides instructions to a client newly diagnosed with type 1 diabetes mellitus. The nurse recognizes accurate understanding of measures to prevent diabetic ketoacidosis when the client makes which statement? 1. "I will stop taking my insulin if I'm too sick to eat." 2. "I will decrease my insulin dose during times of illness." 3. "I will adjust my insulin dose according to the level of glucose in my urine." 4. "I will notify my health care provider (HCP) if my blood glucose level is higher than 250 mg/dL."

ANS: 4 "I will notify my health care provider (HCP) if my blood glucose level is higher than 250 mg/dL." Rationale: During illness, the client with type 1 diabetes mellitus is at increased risk of diabetic ketoacidosis, due to hyperglycemia associated with the stress response and due to a typically decreased caloric intake. As part of sick day management, the client with diabetes should monitor blood glucose levels and should notify the HCP if the level is higher than 250 mg/dL (14.2 mmol/L). Insulin should never be stopped. In fact, insulin may need to be increased during times of illness. Doses should not be adjusted without the HCP's advice and are usually adjusted on the basis of blood glucose levels, not urinary glucose readings.

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? 1. It is timed to release programmed doses of either short-duration or NPH insulin into the bloodstream at specific intervals. 2. It continuously infuses small amounts of NPH insulin into the bloodstream while regularly monitoring blood glucose levels. 3. It is surgically attached to the pancreas and infuses regular insulin into the pancreas. This releases insulin into the bloodstream. 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.

ANS: 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. Rationale: 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.

Which assessment finding in a client signifies a mild form of hypocalcemia? 1. Seizures 2. Hand spasms 3. Severe muscle cramps 4. Numbness around the mouth

ANS: 4 Rationale: A numbness or tingling sensation around the mouth or in the hands and feet indicates mild to moderate hypocalcemia. Seizures, hand spasms, and severe muscle cramps are associated with severe hypocalcemia.

The nurse is caring for a client scheduled for a transsphenoidal hypophysectomy. The preoperative teaching instructions should include which statement? 1. "Your hair will need to be shaved." 2. "You will receive spinal anesthesia." 3. "You will need to ambulate after surgery." 4. "Brushing your teeth needs to be avoided for at least 2 weeks after surgery."

ANS: 4 Rationale: 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.

Which hormonal deficiency causes diabetes insipidus in a client? 1. Prolcatin 2. Thyrotropin 3. Luteinizing hormone 4. Antidiuretic hormone (ADH)

ANS: 4 Rationale: ADH deficiency causes diabetes insipidus. Decreased levels of prolactin may cause decreased amounts of milk secretion after birth. Decreased levels of thyrotropin cause hypothyroidism, weight gain, and lethargy. Luteinizing hormone deficiency causes menstrual abnormalities, decreased libido, and breast atrophy.

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

ANS: 4 Rationale: 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.

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

ANS: 4 Rationale: 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.

Which nursing intervention is appropriate during the first 24 hours after a thyroidectomy when the nurse is concerned about thyroid storm? 1. Perform range-of-motion-exercises. 2. Humidify the room air continuously 3. Assess for hoarseness every 2 hours. 4. Check vital signs every 2 hours after they stabilize.

ANS: 4 Rationale: Checking vital signs helps detect complications such as thyrotoxic crisis, hemorrhage, and respiratory obstruction that may occur early in the postoperative period. Range-of-motion exercises should not begin until 2 to 4 days postoperatively because they can disrupt the suture line. A humidifier can contribute to the spread of bacteria and infection and is contraindicated. Hoarseness and voice weakness usually are temporary and not life threatening; it is appropriate to observe for thyroid storm, hemorrhage, and respiratory obstruction in the first 24 hours.

A client with diabetes mellitus who shows decreased glucose tolerance is at risk for which complication? 1. Cystitis 2. Thin and dry skin 3. Decreased bone density 4. Frequent yeast infections

ANS: 4 Rationale: Decreased glucose tolerance may cause frequent yeast infections, but it is not associated with the risk of cystitis, thin and dry skin, and decreased bone density. The risk of cystitis, thin and dry skin, and decreased bone density are due to decreased ovarian production of estrogen.

Which information would the nurse provide to a client taking dulaglutide? 1. Give with insulin. 2. Administer medication orally. 3. Works without exercise. 4. Perform self-injection weekly.

ANS: 4 Rationale: Dulaglutide is an injection that, unlike insulin, is only administered subcutaneously once a week. It is not administered with insulin, it is not an oral medication, and it works with modified diet and exercise.

Before having surgery, a client with type 1 diabetes insulin requirements are elevated but well controlled. Which insulin requirements would the nurse anticipate for this client postoperatively? 1. Decrease 2. Fluctuate 3. Increase sharply 4. Remain elevated

ANS: 4 Rationale: Emotional and physical stress may cause insulin requirements to remain elevated in the postoperative period. Insulin requirements will remain elevated rather than decrease. Fluctuating insulin requirements usually are associated with noncompliance, not surgery. A sharp increase in the client's insulin requirements may indicate sepsis, but this is not expected.

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? 1. Encourage the client's expression of feelings. 2. Assess the client's understanding of the disease process. 3. Encourage family members to share their feelings about the disease process. 4. Encourage the client to recognize that the body changes need to be dealt with.

ANS: 4 Rationale: 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.

When teaching a client with type 2 diabetes, which statement by the nurse reflects accurate information about preparing for a serum glucose test? 1. "Eat your usual breakfast." 2. "Have clear liquids for breakfast." 3. "Take your medication before the test." 4. "Do not ingest anything before the test."

ANS: 4 Rationale: Fasting before the test is indicated for accurate and reliable results; food before the test will increase serum glucose levels through metabolism of the nutrients. Food should not be ingested before the test; food will increase the serum glucose level, negating accuracy of the test. Instructing the client to have clear liquids for breakfast is inappropriate; some clear fluids contain simple carbohydrates, which will increase the serum glucose level. Medications are withheld before the test because of their influence on the serum glucose level.

The nurse is reviewing the record of a client admitted to the hospital with a diagnosis of pheochromocytoma. The nurse reads the assessment findings and expects to note documentation of which major symptom associated with this condition? 1. Glycosuria 2. Diaphoresis 3. Weight loss 4. Hypertension

ANS: 4 Rationale: Hypertension is the major symptom associated with pheochromocytoma. Glycosuria, weight loss, and diaphoresis also are clinical manifestations of pheochromocytoma; however, they are not major symptoms.

The nurse is reviewing the health care provider's (HCP'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 HCP's prescriptions? 1. A decreased-calorie diet 2. An increased-calorie diet 3. A decreased amount of NPH insulin daily insulin 4. An increased amount of NPH insulin daily insulin

ANS: 4 Rationale: 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 caring for a client admitted to the emergency department with diabetic ketoacidosis (DKA). In the acute phase, the nurse plans for which priority intervention? 1. Correct the acidosis. 2. Administer 5% dextrose intravenously. 3. Apply a monitor for an electrocardiogram. 4. Administer short-duration insulin intravenously.

ANS: 4 Rationale: 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.

The nurse recalls that which cells produce the thyrocalcitonin hormone? 1. Islet cells 2. Adrenal cells 3. Pituitary cells 4. Parafollicular cells

ANS: 4 Rationale: Parafollicular cells produce thyrocalcitonin hormone. This hormone helps in the regulation of serum calcium levels. Islet cells are responsible for the production of hormones such as insulin and glucagon. Adrenal cells are responsible for the production of hormones such as cortisol and aldosterone. Pituitary cells are responsible for the production of growth hormone, prolactin, and adrenocorticotropic hormone.

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? 1. "What is is that you don't understand?" 2. "You can't always depend on your family to help." 3. "It's not really necessary for you to remember this." 4. "Let me go over the type of insulins with you again."

ANS: 4 Rationale: 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.

Which hormone is released from the pancreas? 1. Oxytocin 2. Prolactin 3. Calcitonin 4. Somatostatin

ANS: 4 Rationale: Somatostatin is a hormone produced by the pancreas that inhibits the release of insulin and glucagon. Oxytocin is a hormone produced by the posterior pituitary gland that acts on the uterus and mammary glands. Prolactin is a hormone produced by the anterior pituitary gland that targets the ovaries and mammary glands in women and testes in men. Calcitonin is a hormone produced by the thyroid gland that interacts with bone tissue.

The home care nurse visits a client with a diagnosis of hyperparathyroidism who is taking furosemide and provides dietary instructions to the client. Which statement by the client indicates a need for additional instruction? 1. "I need to eat foods high in potassium." 2. "I need to drink at least 2 to 3 L of fluid daily." 3. "I need to eat small, frequent meals and snacks if nauseated." 4. "I need to increase my intake of dietary items that are high in calcium."

ANS: 4 Rationale: The aim of treatment in the client with hyperparathyroidism is to increase the renal excretion of calcium and decrease gastrointestinal absorption and bone resorption of calcium. Dietary restriction of calcium may be used as a component of therapy. The client should eat foods high in potassium, especially if the client is taking furosemide. Drinking 2 to 3 L of fluid daily and eating small, frequent meals and snacks if nauseated are appropriate instructions for the client.

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

ANS: 4 Rationale: 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.

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? 1. "I will check my blood glucose level every day at 5:00 p.m." 2. "I will check my blood glucose level 1 hour after each meal." 3. "I will check my blood glucose level 2 hours after each meal." 4. "I will check my blood glucose level before each meal and at bedtime."

ANS: 4 Rationale: 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.
