The fructosamine assay is a diagnostic test used to assess the degree of diabetic control of
blood sugar over the preceding 2- to 3-week period. The fructosamine assay is a better tool for
the older adult as it is less influenced by age. The fructosamine assay is not specific to type 1or
type 2 diabetes. Its accuracy is not affected by hypothyroidism. While the fructosamine assay is
simpler and cheaper than an HbA1c test, the accuracy of results for this patient takes priority.
The nurse is caring for a patient who is scheduled to undergo a glucose tolerance test next
week. The patient's daily medications include an antihypertensive, oral contraceptives, and
over-the-counter (OTC) vitamin C and calcium supplements. The nurse should instruct the
patient to withhold which medication before the test?
a. Antihypertensive agent
b. Oral contraceptive
c. Vitamin C
d. Calcium supplement - CORRECT ANSWER-b. Oral contraceptive
,Birth control pills will affect the reliability of the glucose tolerance test and should be withheld.
Antihypertensive agents, vitamin C, and calcium supplements do not affect the reliability of
glucose screening tests.
Pituitary adenoma antagonizes insulin. This benign tumor results in which imbalance?
a. Hyperinsulinism
b. Hyperglycemia
c. Hypopituitarism
d. Hypoglycemia - CORRECT ANSWER-b. Hyperglycemia
The tumor interferes with the effectiveness of insulin, resulting in hyperglycemia.
A patient who had a hypophysectomy 3 days ago begins to have 3000 mL of urine output every
shift and complains of thirst and a dry mouth. Which problem does the nurse suspect?
a. Overreaction to diuretics
b. Diabetes insipidus (DI)
c. Diabetes mellitus
d. Glucose intolerance - CORRECT ANSWER-b. Diabetes insipidus (DI)
DI is a complication of a hypophysectomy. The posterior lobe of the pituitary gland controls
urinary output; when this portion of the pituitary is removed or damaged, there is no secretion
of antidiuretic hormone to stop excessive urine output.
A patient with central diabetes insipidus (DI) likely has which occurrence as part of his health
history?
,a. Brain surgery to remove a tumor
b. A kidney disorder
c. Water addiction
d. A thyroid disorder - CORRECT ANSWER-a. Brain surgery to remove a tumor
Central DI is caused by insult to the pituitary that results from a brain injury or invasive brain
surgery. Kidney disorders, water addiction, and thyroid disorders do not cause central DI.
The nurse is aware that the severe dehydration associated with diabetes insipidus (DI) can lead
which serious electrolyte imbalance?
a. Hypercalcemia
b. Hypernatremia
c. Hypocalcemia
d. Hyperkalemia - CORRECT ANSWER-b. Hypernatremia
The loss of potassium in the large volume of urine depletes the compensatory mechanisms and
hypernatremia results.
The nurse is educating a patient with a simple goiter. Which statement indicates that the patient
needs additional instruction?
a. "The lump on my throat is my enlarged thyroid."
b. "Treatment stops enlargement of the goiter."
c. "I am aware this goiter could develop into cancer."
d. "I'm glad my treatment will make this thing go away." - CORRECT ANSWER-d. "I'm glad my
treatment will make this thing go away."
, Treatment usually arrests the growth of the goiter but usually does not diminish the size of the
growth unless diagnosis is made early in the disease before growth has become excessive.
The nurse is caring for a patient with a goiter. The nurse correctly uses which technique to
administer potassium iodide solution?
a. Pour the solution over ice to increase palatability.
b. Dilute the solution and administer it through a straw.
c. Administer the solution on an empty stomach.
d. Mix the solution with an antacid to reduce gastric irritation. - CORRECT ANSWER-b. Dilute the
solution and administer it through a straw.
The solution should be diluted and drunk through a straw to avoid staining of teeth.
The nurse is reviewing the health history of a patient. Which behavior is linked to increased
probability of developing Grave disease?
a. Smoking
b. Long-term use of oral contraceptives
c. Excessive alcohol consumption
d. Use of St. John wort - CORRECT ANSWER-a. Smoking
Primary hyperthyroidism is also known as Grave disease or toxic goiter. Medications containing
iodine, such as amiodarone (an antidysrhythmic heart medication), can predispose to
hyperthyroidism. In addition, it has been discovered recently that people who smoke have
nearly twice the risk of developing hyperthyroidism when compared with nonsmokers.
The patient with hyperthyroidism is undergoing ablation therapy with radioactive iodine. Which
precaution is most important for the nurse to employ?
