A client who was diagnosed with type 1 diabetes14 years ago is admitted to the medical-surgical unit with abdominal pain. On admission, the client's blood glucose level is 470 mg/dl. Which finding is most likely to accompany this blood glucose level?
Correct Answer
B. Rapid, thready pulse
Explanation
RATIONALE: This client's abnormally high blood glucose level indicates hyperglycemia, which typically causespolyuria,polyphagia, andpolydipsia. Because polyuria leads to fluid loss, the nurse should expect to assess signs of deficient fluid volume, such as a rapid, thready pulse; decreased blood pressure; and rapid respirations. Cool, moist skin and arm and leg trembling are associated withhypoglycemia. Rapid respirations — not slow, shallow ones — are associated with hyperglycemia.

A nurse should expect to administer which medication to a client with gout?
Correct Answer
C. Colchicine
Explanation
RATIONALE: A disease characterized by joint inflammation (especially in the great toe), gout is caused by urate crystal deposits in the joints. The physician orders colchicine to reduce these deposits and thus ease joint inflammation. Although aspirin reduces joint inflammation and pain in clients with osteoarthritis and rheumatoid arthritis, it isn't indicated for gout because it has no effect on urate crystal formation. Furosemide, adiuretic, doesn't relieve gout. Calcium gluconate reverses a negative calcium balance and relieves muscle cramps, it doesn't treat gout.

A nurse administered neutral protamine Hagedorn (NpH) insulin to a client with diabetes mellitusat 7 a.m. At what time should the nurse expect the client to be most at risk forhypoglycemia?
Correct Answer
C. 4 p.m.
Explanation
RATIONALE: NPH is an intermediate-acting insulin that peaks 8 to 12 hours after administration. Because the nurse administered NPH insulin at 7 a.m., the client is at greatest risk for hypoglycemia from 3 to 7 p.m.

A client with long-standing type 1 diabetesis admitted to the hospital with unstableangina pectoris. After the client's condition stabilizes, the nurse evaluates the diabetes management regimen. The nurse learns that the client sees the physician every 4 weeks, injects insulin after breakfast and dinner, and measures blood glucose before breakfast and at bedtime. Consequently, the nurse should formulate a nursing diagnosis of:
Correct Answer
C. Deficient knowledge (treatment regimen).
Explanation
RATIONALE: The client should inject insulin before, not after, breakfast and dinner — 30 minutes before breakfast for the a.m. dose and 30 minutes before dinner for the p.m. dose. Therefore, the client has a knowledge deficit regarding when to administer insulin. By taking insulin, measuring blood glucose levels, and seeing the physician regularly, the client has demonstrated the ability and willingness to modify his lifestyle as needed to manage the disease. This behavior eliminates the nursing diagnoses of Impaired adjustmentandDefensive coping.Because the nurse, not the client, questioned the client's health practices related to diabetes management, the nursing diagnosis ofHealth-seeking behaviorsisn't warranted.

When caring for a client with diabetes insipidus, the nurse expects to administer:
Correct Answer
A. Vasopressin (Pitressin).
Explanation
RATIONALE: Because diabetes insipidus results from decreased antidiuretic hormone (vasopressin) production, the nurse should expect to administer synthetic vasopressin for hormone replacement therapy. Furosemide, a diuretic, is contraindicated because a client with diabetes insipidus experiencespolyuria. Insulin and dextrose are used to treatdiabetes mellitusand its complications, not diabetes insipidus.

A client with type 1 diabetesmust undergo bowel resection in the morning. How should the nurse proceed while caring for him on the morning of surgery?
Correct Answer
A. Administer half of the client's typical morning insulin dose as ordered.
Explanation
RATIONALE: If the nurse administers the client's normal daily dose of insulin while he's on nothing-by-mouth status before surgery, he'll experience hypoglycemia. Therefore, the nurse should administer half the daily insulin dose as ordered. Oral antidiabetic agents aren't effective for type 1 diabetes.

After a 3-month trial of dietary therapy, a client with type 2 diabetesstill has blood glucose levels above 180 mg/dl. The physician adds glyburide (DiaBeta), 2.5 mg P.O. daily, to the treatment regimen. The nurse should instruct the client to take the glyburide:
Correct Answer
A. 30 minutes before breakfast.
Explanation
RATIONALE: Like other oral antidiabetic agents ordered in a single daily dose, glyburide should be taken with breakfast or 30 minutes before breakfast. If the client takes glyburide later, such as in mid-morning, after dinner, or at bedtime, the drug won't provide adequate coverage for all meals consumed during the day.

A nurse has just been trained in how to use and care for a new blood glucose monitor. Which nursing intervention demonstrates proper use of a blood glucose monitor?
Correct Answer
C. Calibrating the machine after installing a new battery
Explanation
RATIONALE: To obtain accurate readings, the nurse should calibrate the machine whenever a new battery is installed. To adhere to standard precautionsand prevent contact with blood, the nurse's hands should remain gloved throughout blood glucose testing. The nurse should drop the blood — not smear it — onto the reagent pad because smearing can cause an inaccurate reading.

A physician orders acarbose (Precose), an alpha-glucosidase inhibitor, for a client with type 2 diabetes. Which statement by the client indicates a need for additional teaching?
Correct Answer
A. "If I have hypoglycemia, I should eat some sugar, not dextrose."
Explanation
RATIONALE: The client indicates a need for additional teaching if he states that he'll eat sugar if he has hypoglycemia. Acarbose delays glucose absorption. So when treating hypoglycemia, the client should take an oral form of dextrose rather than a product containing table sugar. The alpha-glucosidase inhibitors work by delaying the carbohydrate digestion and glucose absorption, not by stimulating the pancreas to release more insulin. It's safe for the client to be on a regimen that includes insulin and an alpha-glucosidase inhibitor. The client should take the drug at the start of a meal, not 30 minutes to 1 hour before.

A client with hypothyroidismis afraid of needles and doesn't want to have his blood drawn. What should the nurse say to help alleviate his concerns?
Correct Answer
D. "I'll stay here with you while the technician draws your blood."
Explanation
RATIONALE: The nurse should tell the client that she will stay with him as the blood is drawn. This response provides the client with the reassuring presence of the nurse and enhances the therapeutic alliance, possibly providing a greater opportunity to educate the client. Although telling the client that blood won't need to be drawn as often when thyroid levels are stable provides the client with a rationale for needing blood work, it's more appropriate for the nurse to stay with the client. Saying that the procedure will be over quickly or that the physician has ordered the blood draw ignores the client's stated fear.

A nurse is caring for a client in acute addisonian crisis. Which test result does the nurse expect to see?
Correct Answer
A. Serum potassium level of 6.8 mEq/L
Explanation
RATIONALE: A serum potassium level of 6.8 mEq/L indicates hyperkalemia, which can occur in adrenal insufficiency as a result of reduced aldosterone secretion. A BUN level of 2.3 mg/dl is lower than normal. A client in addisonian crisis is likely to have an increased BUN level because the glomerular filtration rate is reduced. A serum sodium level of 156 mEq/L indicates hypernatremia. Hyponatremia is more likely in this client because of reduced aldosterone secretion. A serum glucose level of 236 mg/dl indicates hyperglycemia. This client is likely to have hypoglycemia caused by reduced cortisol secretion, which impairs glyconeogenesis.

A client is diagnosed with syndrome of inappropriate antidiuretic hormone(SIADH). Laboratory results reveal serum sodium level 130 mEq/L and urine specific gravity 1.030. Which nursing intervention helps prevent complications associated with SIADH?
Correct Answer
A. Restricting fluids to 800 ml/day
Explanation
RATIONALE: Excessive release of antidiuretic hormone (ADH) disturbs fluid and electrolyte balance in SIADH. The excessive ADH causes an inability to excrete dilute urine, retention of free water, expansion of extracellular fluid volume, and hyponatremia. Symptomatic treatment begins with restricting fluids to 800 ml/day. Vasopressin is administered to clients with diabetes insipidusa condition in which circulating ADH is deficient. Elevating the head of the bed decreases vascular return and decreases atrial-filling pressure, which increases ADH secretion, thus worsening the client's condition. The client's sodium is low and, therefore, shouldn't be restricted.

A nurse is preparing a client with type 1 diabetesfor discharge. The client can care for himself; however, he's had a problem with unstable blood glucose levels in the past. Based on the client's history, he should be referred to which health care worker?
Correct Answer
B. Dietitian
Explanation
RATIONALE: The client should be referred to a dietitian, who will help him gain better control of his blood glucose levels. The client can care for himself, so a home health agency isn't necessary. The client shows no signs of needing a psychiatric referral, and referring the client to a psychiatrist isn't in the nurse's scope of practice.

A client is diagnosed with syndrome of inappropriate antidiuretic hormone(SIADH). The nurse informs the client that the physician will orderdiuretictherapy and restrict fluid and sodium intake to treat the disorder. If the client doesn't comply with the recommended treatment, which complication may arise?
Correct Answer
A. Cerebral edema
Explanation
RATIONALE: Noncompliance with treatment for SIADH may lead to water intoxication from fluid retention caused by excessive antidiuretic hormone. This, in turn, limits water excretion and increases the risk for cerebral edema. Hypovolemicshockresults from, severe deficient fluid volume; in contrast, SIADH causes excess fluid volume. The major electrolyte disturbance in SIADH is dilutional hyponatremia, not hyperkalemia. Because SIADH doesn't alter renal function, potassium excretion remains normal; therefore, severe hyperkalemia doesn't occur.Tetanyresults from hypocalcemia, an electrolyte disturbance not associated with SIADH.

Although it's important that the client's shoes fit properly, this isn't the only reason the client's feet need to be checked. Telling the client that diabetes mellitus increases the risk of infectionor stating that the circulation in the client's feet indicates the severity of his diabetes doesn't provide the client with complete information.

A nurse is assessing a client with possible Cushing's syndrome. In a client with Cushing's syndrome, the nurse expects to find:
Correct Answer
C. Deposits of adipose tissue in the trunk and dorsocervical area.
Explanation
RATIONALE: Because of changes in fat distribution, adipose tissue accumulates in the trunk, face (moon face), and dorsocervical areas (buffalo hump). Hypertension is caused by fluid retention. Skin becomes thin and bruises easily because of a loss of collagen. Muscle wasting causes muscle atrophy and thin extremities.

A nurse should perform which intervention for a client with Cushing's syndrome?
Correct Answer
C. Explain that the client's pHysical changes are a result of excessive corticosteroids.
Explanation
RATIONALE: The nurse should explain to the client that Cushing's syndrome causes physical changes related to excessive corticosteroids. Clients with hyperthyroidism, not Cushing's syndrome, are heat intolerant and must have cool clothing and bedding. Clients with Cushing's syndrome should have a high-protein, not low-protein, diet. Clients withAddison's diseasemust increase sodium intake and fluid intake in times of stress of prevent hypotension.

A female client is being successfully treated for Cushing's syndrome. The nurse should expect a decline in:
Correct Answer
A. Serum glucose level.
Explanation
RATIONALE: Hyperglycemia, which develops from glucocorticoid excess, is a manifestation of Cushing's syndrome. With successful treatment of the disorder, serum glucose levels decline. Hirsutism, not hair loss, is common in Cushing's syndrome; therefore, with successful treatment, abnormal hair growth declines.Osteoporosisoccurs in Cushing's syndrome; therefore, with successful treatment, bone mineralization increases.Amenorrheadevelops in Cushing's syndrome. With successful treatment, the client experiences a return of menstrual flow, not a decline in it.

A nurse has been caring for a client newly diagnosed with diabetes mellitus. The client is overwhelmed by what he's facing and not sure he can handle giving himself insulin. This client has been discharged and the charge nurse is insisting the nurse hurry because she needs the space for clients being admitted. How should the nurse handle the situation?
Correct Answer
B. Ask the pHysician to delay the discharge because the client requires further teaching.
Explanation
RATIONALE: The nurse's primary concern should be the safety of the client after discharge. She should provide succinct information to the physician concerning the client's needs, express her concern about ensuring the client's safety, and ask the physician to delay the client's discharge. The nurse shouldn't suggest that the client rely on a friend or family member because she doesn't know if a friend or family member will be available to help. Refusing to rush and telling the charge nurse she isn't sure the client will be safe demonstrate appropriate intentions, but these actions don't alleviate the pressure to discharge the client. Asking a physician to refer the client to a diabetic nurse-educator addresses the client's needs, but isn't the best response because there's no guarantee a diabetic nurse-educator will be available on such short notice.

Capillary glucose monitoring is being performed every 4 hours for a client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which he receives 8 units of regular insulin. The nurse should expect the dose's:
Correct Answer
C. Onset to be at 2:30 p.m. and its peak to be at 4 p.m.
Explanation
RATIONALE: Regular insulin, which is a short-acting insulin, has an onset of 15 to 30 minutes and a peak of 2 to 4 hours. Because the nurse gave the insulin at 2 p.m., the expected onset would be from 2:15 to 2:30 p.m. and the peak from 4 to 6 p.m.

A client with type 1 diabetesis admitted to an acute care facility withdiabetic ketoacidosis. To correct this acute diabetic emergency, which measure should the health care team take first?
Correct Answer
A. Initiate fluid replacement therapy.
Explanation
RATIONALE: The health care team first initiates fluid replacement therapy to prevent or treat circulatory collapse caused by severe dehydration. Although diabetic ketoacidosis results from insulin deficiency, the client must have an adequate fluid volume before insulin can be administered; otherwise, the drug won't circulate throughout the body effectively. Therefore, insulin administration follows fluid replacement therapy. Determining and correcting the cause of diabetic ketoacidosis are important steps, but the client's condition must first be stabilized to prevent life-threatening complications.

A client is scheduled for a transsphenoidal hypophysectomyto remove a pituitary tumor. Preoperatively, the nurse should assess for potential complications by:
Correct Answer
D. Performing capillary glucose testing every 4 hours.
Explanation
RATIONALE: The nurse should perform capillary glucose testing every 4 hours because excess cortisol may cause insulin resistance, placing the client at risk for hyperglycemia. Urine ketone testing isn't indicated because the client does secrete insulin and, therefore, isn't at risk for ketosis. Urine specific gravity testing isn't indicated because although fluid balance can be compromised, it usually isn't dangerously imbalanced. Temperature regulation may be affected by excess cortisol and isn't an accurate indicator of potential complications such asinfection.

Which statement best indicates that a client understands how to administer his own insulin injections?
Correct Answer
D. "I wrote down the steps in case I forget what to do."
Explanation
RATIONALE: The fact that the client has written down each step of insulin administration provides the best assurance that he'll follow through with all the proper steps. Awareness of air bubbles and hand washing indicate that the client understands certain aspects of giving an injection, but doesn't confirm he understands all of the steps. Saying that he can ask a friend or neighbor for help indicates a need for further instruction.

A nurse teaches a client with newly diagnosed hypothyroidismabout the need for thyroid hormone replacement therapy to restore normal thyroid function. Which thyroid preparation is the agent of choice for thyroid hormone replacement therapy?
Correct Answer
D. Levothyroxine (Synthroid)
Explanation
RATIONALE: Levothyroxine is the agent of choice for thyroid hormone replacement therapy because its standard hormone content provides predictable results. Methimazole is an antithyroid medication used to treat hyperthyroidism. Thyroid USP desiccated and liothyronine are no longer used for thyroid hormone replacement therapy because they may cause fluctuating plasma drug levels, increasing the risk of adverse effects.

A physician orders blood glucose levels every 4 hours for a 4-year-old child with brittle type 1 diabetes. The parents are worried that drawing so much blood will traumatize their child. How can the nurse best reassure the parents?
Correct Answer
A. "Your child will need less blood work as his glucose levels stabilize."
Explanation
RATIONALE: Telling the parents that the number of blood draws will decrease as their child's glucose levels stabilize engages them in the learning process and gives them hope that the present discomfort will end as the child's condition improves. Telling the parents that their child won't remember the experience disregards their concerns and anxiety. The nurse shouldn't offer to ask the physician if he can reduce the number of blood draws; the physician needs the laboratory results to monitor the child's condition properly. Although telling the parents that the laboratory technicians are gentle and use tiny needles may be reassuring, it isn't the most appropriate response.

A client is taking glyburide (DiaBeta), 1.25 mg P.O. daily, to treat type 2 diabetes. Which statement indicates the need for further client teaching about managing this disease?
Correct Answer
D. "I skip lunch when I don't feel hungry."
Explanation
RATIONALE: The client requires further teaching if he states that he skips meals. A client who is receiving an oral antidiabetic agent should eat meals on a regular schedule because skipping a meal increases the risk of hypoglycemia. Carrying hard candy, avoiding exposure to the sun, and always wearing a medical identification bracelet indicate effective teaching.

A client with newly diagnosed type 2 diabetesis admitted to the metabolic unit. The primary goal for this admission is education. Which goal should the nurse incorporate into her teaching plan?
Correct Answer
D. Weight reduction through diet and exercise
Explanation
RATIONALE: Type 2 diabetes is commonly obesity-related; therefore, weight reduction may enhance the normalization of the blood glucose level. Weight reduction should be achieved by a healthy diet and exercise to increase carbohydrate metabolism. Blood glucose levels should be maintained within normal limits to prevent the development of diabetic complications. Clients with type 1 or 2 diabetes shouldn't smoke at all because of the increased risk of cardiovascular disease. A funduscopic examination should be done yearly to identify early signs of diabetic retinopathy.

A nurse hears a staff member giving incorrect information to the family of a client newly diagnosed with diabetes mellituswho is being discharged to home. The nurse wants to make sure the family has the proper information before the client is discharged. What should she do?
Correct Answer
A. Have the nurse step outside of the room, discuss the situation, and use it as a learning opportunity.
Explanation
RATIONALE: The nurse should use this situation as a learning opportunity for her colleague by asking her to step outside of the room to discuss the situation. Telling the nurse that she's providing incorrect information is too blunt and corrective. Going into the room to correct the teaching would undermine the nurse doing the teaching.

A client newly diagnosed with diabetes mellitusasks why he needs ketone testing when the disease affects his blood glucose levels. How should the nurse respond?
Correct Answer
B. "Ketones will tell us if your body is using other tissues for energy."
Explanation
RATIONALE: The nurse should tell the client that ketones are a byproduct of fat metabolism and that ketone testing can determine whether the body is breaking down fat to use for energy. The spleen doesn't release ketones when the body can't use glucose. Although ketones can damage the eyes and kidneys and help the physician evaluate the severity of a client's diabetes, these responses by the nurse are incomplete.

A client with diabetes mellitushas a prescription for 5 units of U-100 regular insulin and 25 units of U-100 isophane insulinsuspension(NpH) to be taken before breakfast. At about 4:30 p.m., the client experiences headache, sweating, tremor, pallor, and nervousness. What is the most probable cause of these signs and symptoms?
Correct Answer
B. Serum glucose level of 52 mg/dl
Explanation
RATIONALE: Headache, sweating, tremor, pallor, and nervousness typically result from hypoglycemia, an insulin reaction in which serum glucose level drops below 70 mg/dl. Hypoglycemia may occur 4 to 18 hours after administration of isophane insulin suspension or insulin zinc suspension (Lente), which are intermediate-acting insulins. Although hypoglycemia may occur at any time, it usually precedes meals.Hyperglycemia, in which serum glucose level is above 180 mg/dl, causes such early manifestations as fatigue, malaise, drowsiness,polyuria, andpolydipsia. A serum calcium level of 8.9 mg/dl or 10.2 mg/dl is within normal range and wouldn't cause the client's symptoms.
