A. "Metformin stimulates the pancreas to produce more insulin."
Metformin does not stimulate the pancreas to produce more insulin; that action is characteristic of sulfonylureas.
B. "Metformin increases the absorption of glucose in the intestines."
Metformin does not increase the absorption of glucose in the intestines; rather, it works by reducing the amount of glucose released into the bloodstream.
C. "Metformin decreases glucose production in the liver and improves insulin sensitivity."
Metformin primarily decreases glucose production in the liver and improves insulin sensitivity in peripheral tissues, which helps lower blood sugar levels. This makes it effective for managing type 2 diabetes.
D. "Metformin decreases the breakdown of fat in the body."
While metformin can have effects on fat metabolism, its primary action is not to decrease fat breakdown but to manage blood glucose levels.

The nurse is caring for a client who experienced a severe headache. When the prescribed dose of analgesics did not cause relief, the client took double the dosage 1 hour later. The nurse should assess the client for what adverse effect?
A. An allergic reaction
An allergic reaction is a possible response to medication, but it is not directly related to doubling the dosage.
B. Anaphylactic reaction
Anaphylactic reaction is a severe and rapid allergic response; while possible, it is not the most likely consequence of an overdose in this context.
C. Poisoning
Poisoning is a likely concern when a client takes double the prescribed dosage of analgesics, especially if the medication has a narrow therapeutic index or is known to cause toxicity at high doses.
D. Sedative effects
Sedative effects could occur depending on the analgesic used, but poisoning is a more pressing concern following an overdose.
