Which of the following statements best describes the effect of Donepezil on Alzheimer’s disease?

• Subcutaneous: A parenteral route where medication is injected into the tissue layer between the skin and muscle. It bypasses the gastrointestinal (GI) tract, allowing for faster absorption of certain medications like insulin or heparin.
• NG Tube: A form of enteral administration that delivers medication directly into the stomach via a nasogastric tube. This route utilizes the GI tract and is often used for patients who cannot swallow.
• Oral: A classic enteral route involving medication taken by mouth and absorbed through the digestive tract. It is the most common and convenient method of drug delivery.
• Rectal: An enteral route that involves administration of medication into the rectum, where it is absorbed by the lower GI tract. It is often used when oral administration is not feasible.
• Intramuscular: A parenteral route where medication is injected into a muscle, offering faster absorption than enteral routes. Common for vaccines and certain pain medications.
• Intravenous: A parenteral route that delivers medication directly into the bloodstream. It provides the most rapid onset of action and is used for critical care, emergencies, and precise dosing.

A. "Limit your fluid intake to meal times.": Fluid restriction is not a standard recommendation for patients taking Verapamil unless they have another condition like heart failure. Adequate hydration is important, especially to counter constipation, a known side effect of the drug.
B. "You can expect swelling of the ankles while taking this medication.": While peripheral edema is a known side effect of Verapamil, it is not something patients should expect or accept without reporting. Significant swelling may require dose adjustment or switching medications.
C. "This medication will not affect your heart rate": Verapamil is a calcium channel blocker that slows AV node conduction and reduces heart rate. It is used for conditions like hypertension, angina, and arrhythmias, and can cause bradycardia, especially in high doses.
D. "Increase your daily intake of dietary fiber.": Verapamil frequently causes constipation by decreasing gastrointestinal motility. Increasing dietary fiber, fluid intake, and physical activity are recommended to minimize this side effect and promote regular bowel movements.
