The nurse is administering insulin lispro and will keep in mind that this insulin will start to have an effect within which time frame?
- A. 15 minutes
- B. 1 to 2 hours
- C. 80 minutes
- D. 3 to 5 hours
Correct Answer: A
Rationale: Insulin lispro, a rapid-acting insulin, has an onset of action within 15 minutes, making it effective shortly after administration. The other time frames refer to peak, half-life, or duration.
The nurse is teaching a group of patients about self-administration of insulin. What content is important to include?
- A. Patients need to use the injection site that is the most accessible.
- B. If two different insulins are ordered, they need to be given in separate injections.
- C. When mixing insulins, the cloudy (such as NPH) insulin is drawn up into the syringe first.
- D. When mixing insulins, the clear (such as regular) insulin is drawn up into the syringe first.
Correct Answer: D
Rationale: When mixing insulins, clear (regular) insulin is drawn up first to prevent contamination with cloudy (NPH) insulin. Rotation of injection sites is necessary, and compatible insulins can be mixed in one syringe.
The nurse is teaching patients about self-injection of insulin. Which statement is true regarding injection sites?
- A. Avoid the abdomen because absorption there is irregular.
- B. Choose a different site at random for each injection.
- C. Give the injection in the same area each time.
- D. Rotate sites within the same location for about 1 week before rotating to a new location.
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.

- A. Glitazone
- B. Insulin
- C. Metformin
- D. Sulfonylurea
Correct Answer: B
Rationale: Sitagliptin, a DPP-4 inhibitor, is not typically combined with insulin due to lack of established safety and efficacy. It can be used with metformin, sulfonylureas, or glitazones.
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?

- B. Take this medication in the evening with a snack.
- C. This medication needs to be taken after the midday meal.
- D. It does not matter what time of day you take this medication.
Correct Answer: A
Rationale: Glipizide, a sulfonylurea, is taken 30 minutes before breakfast to align insulin secretion with postprandial glucose rise, mimicking normal physiology.
