Chapter 32 : Diabetes Drugs Questions
Question 1 of 5
A 55-year-old woman with type 2 diabetes has recently been placed on glipizide. She asks the nurse when the best time would be to take this medication. What is the nurse's best response?
Correct Answer: A
Rationale: Glipizide, a sulfonylurea, is taken 30 minutes before breakfast to align insulin secretion with postprandial glucose rise, mimicking normal physiology.
Question 2 of 5
A patient who has type 2 diabetes is scheduled for an oral endoscopy and has been NPO (nothing by mouth) since midnight. What is the best action by the nurse regarding the administration of her oral antidiabetic drugs?
Correct Answer: C
Rationale: NPO status increases hypoglycemia risk with oral antidiabetic drugs, so the prescriber must be contacted for adjusted orders. Giving or withholding without guidance is unsafe.
Question 3 of 5
The nurse is reviewing instructions for a patient with type 2 diabetes who also takes insulin injections as part of the therapy. The nurse asks the patient 'What should you do if your fasting blood glucose is 44 mg/dL?' Which response by the patient reflects a correct understanding of insulin therapy?
Correct Answer: C
Rationale: A fasting blood glucose of 44 mg/dL indicates hypoglycemia, requiring immediate oral glucose intake (e.g., glucose tablets) to raise blood sugar. Insulin would worsen it, and delaying or calling the doctor is not optimal.
Question 4 of 5
The nurse is teaching patients about self-injection of insulin. Which statement is true regarding injection sites?
Correct Answer: D
Rationale: Rotating insulin injection sites within the same location (e.g., abdomen) for about 1 week ensures consistent absorption while preventing tissue damage. Random rotation or avoiding the abdomen is incorrect.
Question 5 of 5
Which action is most appropriate regarding the nurse's administration of a rapid-acting insulin to a hospitalized patient?
Correct Answer: A
Rationale: Rapid-acting insulin, like lispro, should be given within 15 minutes of a meal to match the postprandial glucose spike, mimicking natural insulin response.
