A nurse is caring for a client with a new prescription for gemfibrozil.
Which of the following is an indication of this medication?

Choice A rationale

Rotating injection sites helps prevent lipohypertrophy, which is the thickening of subcutaneous tissue due to repeated insulin injections at the same site.

Choice B rationale

Performing injections at the same location every time increases the risk of lipohypertrophy, leading to poor insulin absorption and erratic glucose control.

Choice C rationale

Administering an additional dose of insulin as needed does not address the issue of lipohypertrophy and can lead to hypoglycemia if not carefully monitored.

Choice D rationale

Insulin is a peptide hormone that must be injected. Taking it orally is ineffective as it would be broken down in the digestive system.

Choice A rationale

While metformin is commonly used as a first-line medication for type 2 diabetes, this choice does not specifically address a critical safety concern related to metformin.

Choice B rationale

Metformin can interact with contrast dyes used in imaging studies, increasing the risk of acute renal failure due to lactic acidosis. Patients need to be aware of this interaction to avoid potential complications.

Choice C rationale

Metformin is used to lower blood glucose levels, not increase them. This choice is incorrect.

Choice D rationale

While metformin is associated with less weight gain compared to other diabetes medications, this choice does not address the critical interaction with contrast dye.
