Unit 3
A patient with acromegaly is treated with a transsphenoidal hypophysectomy. What should the nurse do postoperatively? a. Ensure that any clear nasal drainage is tested for glucose. b. Maintain the patient flat in bed to prevent cerebrospinal fluid (CSF) leakage. c. Assist the patient with toothbrushing every 4 hours to keep the surgical area clean. d. Encourage deep breathing, coughing, and turning to prevent respiratory complications.
A transsphenoidal hypophysectomy involves entry into the sella turcica through an incision in the upper lip and gingiva into the floor of the nose and the sphenoid sinuses. Postoperative clear nasal drainage with glucose content indicates cerebrospinal fluid (CSF) leakage from an open connection to the brain, putting the patient at risk for meningitis
A patient with type 1 diabetes uses 20 U of 70/30 neutral protamine Hagedorn (NPH/regular) in the morning and at 6:00 pm. When teaching the patient about this regimen, what should the nurse emphasize? a. Hypoglycemia is most likely to occur before the noon meal. b. Flexibility in food intake is possible because insulin is available 24 hours a day. c. A set meal pattern with a bedtime snack is necessary to prevent hypoglycemia. d. Premeal glucose checks are required to determine needed changes in daily dosing
C
What should the goals of nutrition therapy for the patient with type 2 diabetes include? a. Ideal body weight b. A special diabetic diet using dietetic foods c. Normal serum glucose and lipid levels d. Five small meals per day with a bedtime snack
C
Which class of oral glucose-lowering agents is most commonly used for people with type 2 diabetes because it reduces hepatic glucose production and enhances tissue uptake of glucose? a. Insulin b. Meglitinide c. Biguanide d. Sulfonylurea
C
What describes the primary difference in treatment for diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic syndrome (HHS)? a. DKA requires administration of bicarbonate to correct acidosis. b. Potassium replacement is not necessary in management of HHS. c. HHS requires greater fluid replacement to correct the dehydration. d. Administration of glucose is withheld in HHS until the blood glucose reaches a normal level.
C The management of DKA is similar to that of HHS except that HHS requires greater fluid replacement because of the severe hyperosmolar state. Bicarbonate is not usually given in DKA to correct acidosis unless the pH is <7.0 because administration of insulin will reverse the abnormal fat metabolism. Total body potassium deficit is possible in both conditions, requiring potassium administration, and in both conditions glucose is added to IV fluids when blood glucose levels fall to 250 mg/dL (13.9 mmol/L).
Following the teaching of foot care to a diabetic patient, the nurse determines that additional instruction is needed when the patient makes which statement? a. "I should wash my feet daily with soap and warm water." b. "I should always wear shoes to protect my feet from injury." c. "If my feet are cold, I should wear socks instead of using a heating pad." d. "I'll know if I have sores or lesions on my feet because they will be painful."
D
. To prevent hyperglycemia or hypoglycemia related to exercise, what should the nurse teach the patient using glucose-lowering agents about the best time for exercise? a. Only after a 15-g carbohydrate snack is eaten b. About 1 hour after eating when blood glucose levels are rising c. When glucose monitoring reveals that the blood glucose is in the normal range d. When blood glucose levels are high, because exercise always has a hypoglycemic effect
B
What are manifestations of diabetic ketoacidosis (DKA) (select all that apply)? a. Thirst b. Metabolic acidosis c. Ketonuria d. Kussmaul respirations e. Dehydration f. Sweet, fruity breath odor
ALL

Clean the skin at the injection site with an alcohol swab before each injection. d. Rotate injection sites from arms to thighs to abdomen with each injection to prevent lipodystrophies
B
: The nurse is assessing a newly admitted diabetic patient. Which observation should be addressed as the priority by the nurse? a. Bilateral numbness of both hands b. Rapid respirations with deep inspiration c. Stage II pressure ulcer on the right heel d. Areas of lumps and dents on the abdomen
B Rapid deep respirations are symptoms of diabetic ketoacidosis (DKA), so this is the priority of care. Stage II pressure ulcers and bilateral numbness are chronic complications of diabetes. The lumps and dents on the abdomen indicate a need to teach the patient about site rotation
A patient with SIADH is treated with water restriction. What does the patient experience when the nurse determines that treatment has been effective? a. Increased urine output, decreased serum sodium, and increased urine specific gravity b. Increased urine output, increased serum sodium, and decreased urine specific gravity c. Decreased urine output, increased serum sodium, and decreased urine specific gravity d. Decreased urine output, decreased serum sodium, and increased urine specific gravity
B The patient with SIADH has water retention with hyponatremia, decreased urine output, and concentrated urine with high specific gravity. Improvement in the patient's condition is reflected by increased urine output, normalization of serum sodium, and more water in the urine, thus decreasing the specific gravity
The patient with diabetes insipidus is brought to the emergency department with confusion and dehydration after excretion of a large volume of urine today even though several liters of fluid were drunk. What is a diagnostic test that the nurse should expect to be done to help make a diagnosis? a. Blood glucose b. Urine specific gravity c. Serum sodium level d. Computed tomography (CT) of the head
B Patients with diabetes insipidus (DI) excrete large amounts of urine with a specific gravity of less than 1.005. Blood glucose would be tested to diagnose diabetes mellitus. The serum sodium level is expected to be low with DI but is not diagnostic. To diagnose central DI a water deprivation test is required. Then a CT of the head may be done to determine the cause. Nephrogenic DI is differentiated from central DI with determination of the level of ADH after an analog of ADH is given.
The home care nurse should intervene to correct a patient whose insulin administration includes a. warming a prefilled refrigerated syringe in the hands before administration. b. storing syringes prefilled with NPH and regular insulin needle-up in the refrigerator. c. placing the insulin bottle currently in use in a small container on the bathroom countertop. d. mixing an evening dose of regular insulin with insulin glargine in one syringe for administration
D

B
A patient with "Addison's disease" comes to the emergency department with complaints of nausea, vomiting, diarrhea, and fever. What collaborative care should the nurse expect? a. IV administration of vasopressors b. IV administration of hydrocortisone c. IV administration of D5 W with 20 mEq KCl d. Parenteral injections of adrenocorticotropic hormone (ACTH)
B "Add"ison = "Add" steriod during crisis
The patient with newly diagnosed diabetes is displaying shakiness, confusion, irritability, and slurred speech. What should the nurse suspect is happening? a. DKA b. Hypoglycemia c. HHS d. Hyperglycemia
B Hypoglycemis = cold calmy need some candy
The nurse should observe the patient for symptoms of ketoacidosis when a. illnesses causing nausea and vomiting lead to bicarbonate loss with body fluids. b. glucose levels become so high that osmotic diuresis promotes fluid and electrolyte loss. c. an insulin deficit causes the body to metabolize large amounts of fatty acids rather than glucose for energy. d. the patient skips meals after taking insulin, leading to rapid metabolism of glucose and breakdown of fats for energy.
C
The patient is diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH). What manifestation should the nurse expect to find? a. Decreased body weight b. Increased plasma osmolality c. Decreased urinary output d. Increased serum sodium levels
C
When caring for a patient with nephrogenic diabetes insipidus, what should the nurse expect the treatment to include? a. Fluid restriction b. A high-sodium diet c. Thiazide diuretics d. Chlorpropamide (Diabinese)
C . In nephrogenic diabetes insipidus, the kidney is unable to respond to ADH, so vasopressin or hormone analogs are not effective. Thiazide diuretics slow the glomerular filtration rate (GFR) in the kidney and produce a decrease in urine output.
. The nurse assesses the diabetic patient's technique of self-monitoring of blood glucose (SMBG) 3 months after initial instruction. Which error in the performance of SMBG noted by the nurse requires intervention? a. Doing the SMBG before and after exercising b. Puncturing the finger on the side of the finger pad c. Cleaning the puncture site with alcohol before the puncture d. Holding the hand down for a few minutes before the puncture
C Cleaning the puncture site with alcohol is not necessary and may interfere with test results and lead to drying and splitting of the fingertips
During care of the patient with SIADH, what should the nurse do? a. Monitor neurologic status at least every 2 hours. b. Teach the patient receiving treatment with diuretics to restrict sodium intake. c. Keep the head of the bed elevated to prevent antidiuretic hormone (ADH) release. d. Notify the health care provider if the patient's blood pressure decreases more than 20 mm Hg from baseline

Administer the usual insulin dosage. b. Hold fluid intake until the nausea subsides. c. Come to the clinic immediately for evaluation and treatment. d. Monitor the blood glucose every 1 to 2 hours and call if it rises over 150 mg/dL (8.3 mmol/L).
A During minor illnesses, the patient with diabetes should continue drug therapy and food intake. Insulin is important because counter regulatory hormones may increase blood glucose during the stress of illness
A 72-year-old woman is diagnosed with diabetes. What does the nurse recognize about the management of diabetes in the older adult? a. It is more difficult to achieve strict glucose control than in younger patients. b. It usually is not treated unless the patient becomes severely hyperglycemic. c. It does not include treatment with insulin because of limited dexterity and vision. d. It usually requires that a younger family member be responsible for care of the patient.
A

: A patient taking insulin has recorded fasting glucose levels above 200 mg/dL (11.1 mmol/L) on awakening for the last five mornings. What should the nurse advise the patient to do first? a. Increase the evening insulin dose to prevent the dawn phenomenon. b. Use a single-dose insulin regimen with an intermediate-acting insulin. c. Monitor the glucose level at bedtime, between 2:00 am and 4:00 am, and on arising. d. Decrease the evening insulin dosage to prevent night hypoglycemia and the Somogyi effect.
C The patient's elevated glucose on arising may be the result of either dawn phenomenon or Somogyi effect. The best way to determine whether the patient needs more or less insulin is by monitoring the glucose at bedtime, between 2:00 am and 4:00 am, and on arising. If predawn levels are below 60 mg/dL, the insulin dose should be reduced. If the 2:00 am to 4:00 am blood glucose is high, the insulin should be increased.
