Glyburide works by which of the following mechanisms?
Stimulating glucose uptake in the skeletal muscles.
Increasing the cells' sensitivity to insulin.
Stimulating the release of insulin from the pancreas.
Inhibiting the breakdown of carbohydrates in the intestines.
The Correct Answer is C
Choice A rationale
Glyburide does not stimulate glucose uptake directly in skeletal muscles. Instead, it acts on pancreatic beta cells, affecting insulin release. Enhancing muscular glucose uptake occurs through insulin’s action downstream.
Choice B rationale
Glyburide does not primarily increase insulin sensitivity. Agents like metformin work to sensitize cells to insulin, but Glyburide functions by stimulating endogenous insulin release.
Choice C rationale
Glyburide stimulates insulin release from pancreatic beta cells by closing ATP-sensitive potassium channels, leading to calcium influx and insulin secretion. This increases circulating insulin, aiding glucose uptake and reducing blood glucose levels.
Choice D rationale
Glyburide does not inhibit carbohydrate breakdown in the intestines. Medications like alpha-glucosidase inhibitors target intestinal enzymes to slow carbohydrate digestion, unlike Glyburide’s pancreatic action.

Correct Answer is A
Explanation
Choice A rationale
A bland diet reduces gastric irritation by avoiding substances that stimulate acid secretion or exacerbate nausea. It includes foods like rice, bananas, and toast that are easy to digest and less likely to provoke symptoms of nausea or vomiting.
Choice B rationale
Opposing the bland diet recommendation for severe nausea ignores scientific evidence that supports its use. Providing a diet rich in spices or acidic foods can worsen symptoms by irritating the gastrointestinal tract further. .
Correct Answer is A
Explanation
Choice A rationale
Strict monitoring of intake and output in CHF patients with furosemide therapy prevents fluid overload and underhydration. Foley catheter placement accurately quantifies urine output, crucial in critically ill patients with diuretic-induced fluid shifts. This ensures precise fluid balance adjustments, improving patient outcomes.
Choice B rationale
Omitting Foley catheter placement in CHF patients risks inaccurate fluid balance monitoring. Furosemide causes frequent, unpredictable urination, complicating intake-output tracking without direct measurement. This approach undermines effective management of diuretic therapy and fluid overload prevention in critical settings. .
