A patient will be starting therapy with a corticosteroid. The nurse reviews the
patient's orders and notes that an interaction may occur if the corticosteroid is taken
with which of these drug classes?
a. Nonsteroidal anti-inflammatory drugs
b. Antibiotics
c. Opioid analgesics
d. Antidepressants
a. Nonsteroidal anti-inflammatory drugs
The use of corticosteroids with aspirin, other NSAIDs, and other ulcerogenic drugs
produces additive gastrointestinal effects and an increased chance for the
development of gastric ulcers. The other options are incorrect.
A patient is taking fludrocortisone (Florinef®) for Addison's disease. His wife is
concerned about all the problems that may occur with this therapy.
Which is a true statement about fludrocortisone therapy?
a. It may cause severe postural hypotension.
b. To minimize gastrointestinal upset, the medication should be taken with food or
milk.
c. The medication should be stopped immediately if nausea or vomiting occurs.
d. Weight gain of 2.3 kg or more in 1 week is an expected adverse effect.
B.
A patient with type 2 diabetes self-administers insulin injections as part of therapy.
What should the nurse tell this patient to do if she has hypoglycemia?
a. Call the physician.
b. Administer regular insulin.
pg. 1
,c. Take an oral form of glucose.
d. Rest until the symptoms pass.
C. The patient can take glucose tablets (liquid or gel), corn syrup, or honey; drink
fruit juice or a nondiet soft drink; or eat a small snack, such as crackers or half a
sandwich.
The nurse is teaching a patient about self-injection of insulin.
What should the nurse tell the patient to do regarding injection sites?
Rotate sites w/in the same location for a week.
**All injections should be rotated in one area, such as the right arm, for about 1
week before rotating to a new location, such as the left arm, the following week.
Each injection should be at least 1.25 to 2.5 cm away from the previous site.
A patient has been prescribed a rapid-acting insulin, such as insulin lispro. What
important information should the nurse give this patient about taking this type of
insulin?
a. It should be taken within 15 minutes of beginning a meal.
b. It should be taken after the meal.
c. Dosing is once daily at the midday meal.
d. It is taken only in the evenings with a snack before bedtime
A.
Six months after starting treatment for type 2 diabetes, a patient has a follow-up
examination. Which laboratory test will best reflect the patient's adherence to the
antidiabetic therapy over the past few months?
Hemoglobin A1c level
A patient with a history of chronic obstructive pulmonary disease (COPD) and
type 2 diabetes has been treated for pneumonia for the past week. He has been
receiving corticosteroids intravenously and antibiotics as part of his therapy. His
pneumonia has resolved, but when the nurse monitors his blood glucose levels, his
blood glucose is still elevated and he requires small amounts of sliding scale
insulin coverage. What is the best explanation for this elevation?
a. The antibiotics may have caused an increase in glucose levels.
b.The corticosteroids may have caused an increase in glucose levels.
pg. 2
,c.His type 2 diabetes has converted to type 1 diabetes.
d.The hypoxia from the COPD has caused an increased need for insulin.
b. The corticosteroids may have caused an increase in glucose levels.
Corticosteroids can antagonize the hypoglycemic effects of insulin, resulting in
elevated blood glucose levels.
A 48-year-old male patient is diagnosed with metabolic syndrome and is started on
biguanide metformin (Glucophage®). He asks the nurse why he needs this drug.
The nurse's best explanation of the purpose of the metformin is that it
a. increases the pancreatic secretion of insulin.
b. decreases glucose production by the liver.
c. increases intestinal absorption of glucose.
d. decreases the pancreatic secretion of insulin.
B. decreases glucose production by the liver.
Metformin works by decreasing glucose production by the liver. It may also
decrease intestinal absorption of glucose and improve insulin receptor sensitivity.
This results in increased peripheral glucose uptake and use and in decreased liver
production of triglycerides and cholesterol.
Which types of insulin can be administered intravenously?
a. Regular insulin
b. NPH insulin
c. insulin glargine (Lantus®)
d. insulin detemir (Levemir®)
A. Regular insulin
Regular insulin is the only insulin product that can be administered intravenously.
Regular insulin is the usual insulin product to be dosed via intravenous bolus,
intravenous infusion, or even intramuscularly. These routes, especially the
intravenous infusion route, are often used in cases of diabetic ketoacidosis, or
coma associated with uncontrolled type 1 diabetes.
When monitoring a patient's response to oral antidiabetic drugs, the nurse knows
that which laboratory result would indicate a therapeutic response?
a. Random blood glucose level 12 mmol/L
pg. 3
, b. Blood glucose level of 11 mmol/L after meals
c. Fasting blood glucose level is 6 mmol/L
d. Evening blood glucose level below 3 mmol/L
c. Fasting blood glucose level is 6 mmol/L
therapeutic effect range
btw 4 to 7 mmol/L before meal
btw 5.0 to 10.0 mmol/L 2hrs after meal
When should the nurse administer acarbose (Glucobay), an α-glucosidase
inhibitor?
a. Thirty minutes before breakfast
b. With the first bite of each main meal
c. Thirty minutes after breakfast
d. Once daily, at bedtime
B.
to prevent excessive postprandial blood glucose elevation
Which is a true statement about prednisone (Winpred®)?
a. It is a short-acting glucocorticoid.
b. It has potent mineralocorticoid activity.
c. It is the preferred oral glucocorticoid for anti-inflammatory purposes.
d. It may be administered by inhalation for the treatment of bronchial asthma.
C.
What important information about taking adrenal drugs is appropriate for the nurse
to give a patient?
a. To maximize their absorption, oral drugs should be taken before meals.
b. The patient should rinse the oral cavity after using the steroid inhalers.
c. Corticosteroids should be taken before bedtime to minimize adrenal suppression.
d. The medication is to be immediately discontinued if a weight gain of more than
2.25 kg occurs in 1 week.
B.
rinsing the oral cavity helps to prevent oral fungal infections from developing.
Which type of drugs can have an adverse interaction with corticosteroids?
a. Nonsteroidal anti-inflammatory drugs (NSAIDs)
