Evolve Q's Flashcards
- Which is a rapid-acting insulin with an onset of action of less than 15 minutes?
A. Insulin glargine (Lantus)
B. Insulin aspart (NovoLog)
C. Insulin detemir (Levemir)
D. Regular insulin (Humulin R)
B
Insulin aspart is a rapid-acting insulin. Insulin glargine and insulin detemir are long-acting insulins. Regular insulin is short acting.
- Which long-acting insulin mimics natural, basal insulin with no peak action and a duration of 24 hours?
A. Insulin glargine (Lantus)
B. Insulin glulisine (Apidra)
C. Regular insulin (Humulin R)
D. NPH insulin
B
Insulin glargine has a duration of action of 24 hours with no peaks, mimicking the natural, basal insulin secretion of the pancreas.
- Which insulin can be administered by continuous intravenous (IV) infusion?
A. Insulin glargine (Lantus)
B. Insulin aspart (Novolog)
C. Insulin detemir (Levemir)
D. Regular insulin (Humulin R)
D
Regular insulin is the only insulin used for IV therapy.
- Assuming the patient eats breakfast at 8:30 AM, lunch at noon, and dinner at 6:00 AM, he or she is at highest risk of hypoglycemia after an 8:00 AM dose of NPH insulin at what time?
10: 00 AM
2: 00 PM
5: 00 PM
8: 00 PM
5:00pm
Breakfast eaten at 8:30 AM would cover the onset of NPH insulin, and lunch will cover the 2 PM time frame. However, if the patient does not eat a mid-afternoon snack, the NPH insulin may be peaking just before dinner without sufficient glucose on hand to prevent hypoglycemia.
- The nurse is preparing a patient for a computed tomography scan using iodine contrast media. Which medication should the nurse question if prescribed one day before the scheduled procedure?
A. Acarbose (Precose)
B. Pioglitazone (Actos)
C. Repaglinide (Prandin)
D. Metformin (Glucophage)
D
The concurrent use of metformin with iodinated (iodine-containing) radiologic contrast media has been associated with both acute renal failure and lactic acidosis. Therefore, metformin should be discontinued the day of the test and for at least 48 hours after the patient undergoes any radiologic study that requires the use of such contrast media.
- Which oral hypoglycemic drug has a quick onset and short duration of action, enabling the patient to take the medication 30 minutes before eating and skip the dose if he or she does not eat?
A. Acarbose (Precose)
B. Metformin (Glucophage)
C. Repaglinide (Prandin)
D. Pioglitazone (Actos)
C
Repaglinide is known as the “Humalog of oral hypoglycemic drugs.” The drug’s very fast onset of action allows patients to take the drug with meals and skip a dose when they skip a meal.
7.ID: 10068760536
Pramlintide (Symlin) is prescribed as supplemental drug therapy to the treatment plan for a patient with type 1 diabetes mellitus. What information should the nurse include when teaching the patient about the action of this medication?
A. Pramlintide slows gastric emptying.
B. Pramlintide increases glucagon excretion. Incorrect
C. Pramlintide stimulates glucose production.
D. Pramlintide corrects insulin receptor sensitivity.
A
Pramlintide is a synthetic form of the naturally occurring hormone amylin. It works by slowing gastric emptying, suppressing glucagon secretion and hepatic glucose production, and increasing satiety (sense of having eaten enough). It is only administered via subcutaneously injection.
- The patient is prescribed 30 units of regular insulin and 70 units of insulin isophane suspension (NPH insulin) subcutaneously every morning. The nurse should provide which instruction to the patient for insulin administration?
A. “Inject the needle at a 30-degree angle.”
B. “Rotate sites at least once or twice a week.”
C. “Use a 23- to 25-gauge syringe with a 1-inch needle to increase insulin absorption.”
D. “Draw up the regular insulin into the syringe first, followed by the cloudy NPH insulin.”
D.
When insulins are mixed, withdraw the regular insulin (clear) first, followed by withdrawing the NPH insulin (cloudy).
- When teaching a patient about insulin glargine (Lantus), which statement by the nurse about this drug is correct?
A. “You can mix this insulin with NPH insulin to enhance its effects on glucose metabolism.”
B. “You cannot mix this insulin with regular insulin and thus will have to take two injections.”
C. “It is often combined with regular insulin to decrease the number of insulin injections per day.”
D. “The duration of action for this insulin is 8 to10 hours, so you will need to take it twice a day.”
B
Insulin glargine is a long-acting insulin with duration of action up to 24 hours. It should not be mixed with any other insulins. It is usually dosed once daily, but it may be dosed every 12 hours depending on the patient’s glycemic response.
- The nurse is providing education to a patient for the prescription glipizide (Glucotrol). The nurse explains this medication is more effective when administered at which time?
A. At bedtime
B. In the morning
C. 15 minutes postprandial
D. 30 minutes before a meal
D
Glipizide works best if given 30 minutes before meals. This allows the timing of the insulin secretion induced by the glipizide to correspond to the elevation in the blood glucose level induced by the meal.
- The nurse will instruct the patient to treat hypoglycemia with which drug?
A. Acarbose (Precose)
B. Propranolol (Inderal)
C. Glucagon (GlucaGen)
D. Bumetanide (Bumex)
C.
Glucagon stimulates glycogenolysis, raising serum glucose levels.
