A client is newly prescribed with metformin (Glucophage) for type 2 diabetes.Which of the following statements indicate that the client understands the teaching of metformin?
Metformin is used as a first-line medication for type 2 diabetes.
Metformin interacts with contrast dye which can increase the risk of acute renal failure.
Metformin is used to increase blood glucose.
Metformin does not cause weight gain.
The Correct Answer is B
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.

Explanation
Choice B rationale
Sucralfate (Carafate) acts by forming a viscous, adhesive substance that binds to the ulcer site, creating a physical barrier protecting it from stomach acid and allowing healing.
Choice A rationale
Sucralfate does not function as an endogenous prostaglandin; it does not mimic or enhance prostaglandin activity in the GI tract.
Choice C rationale
Sucralfate does not neutralize gastric acid; that is the function of antacids.
Choice D rationale
Sucralfate does not antagonize H2 receptors on parietal cells; H2 receptor antagonists are a different class of medication.

Choice A rationale
Tumor enhancer genes is not a recognized term in oncology. DNA repair genes, along with proto-oncogenes and tumor suppressor genes, are critical in cancer development.
Choice B rationale
There are specific genes involved in cancer development, as mentioned in the other options.
Choice C rationale
Proto-oncogenes and tumor suppressor genes are both involved, but DNA repair genes also play a significant role.
Choice D rationale
Proto-oncogenes, tumor suppressor genes, and DNA repair genes collectively contribute to cancer development by either promoting or failing to prevent cell proliferation and damage repair.
