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.

Correct Answer is A
Explanation
Choice A rationale
Metoprolol is a beta-adrenergic blocker that works by decreasing heart rate, myocardial contractility, and cardiac output. It is commonly used to treat hypertension by reducing the workload on the heart and lowering blood pressure.
Choice B rationale
Nitroglycerin is a vasodilator that is used to treat angina by dilating blood vessels and improving blood flow to the heart. It does not have the same mechanism of action as beta-adrenergic blockers.
Choice C rationale
Losartan is an angiotensin II receptor blocker (ARB) that helps relax blood vessels and lower blood pressure. It does not directly decrease heart rate or myocardial contractility like beta-adrenergic blockers.
Choice D rationale
Metformin is an oral hypoglycemic agent used to manage type 2 diabetes by improving insulin sensitivity and reducing glucose production in the liver. It is not used to treat hypertension and does not have the same mechanism of action as beta-adrenergic blockers.
Correct Answer is A
Explanation
Choice A rationale
A receptor antagonist blocks the effects of normal cellular functions by binding to receptor sites and preventing endogenous substances (like hormones or neurotransmitters) from activating those receptors.
Choice B rationale
Receptor antagonists do not accelerate hormones attaching to cell receptor sites; they prevent this process by blocking the receptors.
Choice C rationale
Receptor antagonists do not minimize the risk of other medications becoming toxic. They specifically block the action of certain endogenous substances.
Choice D rationale
Receptor antagonists do not increase the action of cells; rather, they inhibit or block the usual effects.
