ATI NUR 180 Pharmacology Exam | Nurselytic

Correct Answer: B

Rationale: The correct answer is B: Metformin interacts with contrast dye which can increase the risk of acute renal failure. This statement indicates that the client understands a crucial aspect of metformin therapy. Metformin can lead to a rare but serious condition called lactic acidosis, especially when combined with contrast dye used in imaging procedures. This can result in acute renal failure. Understanding this interaction is important for the client's safety.


Choice A is incorrect because while metformin is commonly used as a first-line medication for type 2 diabetes, this statement does not specifically indicate understanding of the medication.


Choice C is incorrect because metformin is actually used to lower blood glucose levels, not increase them.


Choice D is incorrect because metformin is known to be weight-neutral or even promote weight loss, not weight gain.

In summary, understanding the potential interaction between metformin and contrast dye is crucial for clients to prevent serious complications, making choice B the correct answer.
