Flumazenil
Digoxin
Protamine sulfate
Naloxone hydrochloride

Correct Answer is ["B","C","D"]
Explanation
A. Chew tablet to increase bioavailability: Alendronate tablets must be swallowed whole; chewing destroys formulation and increases esophageal irritation risk.
B. Take the medication in the morning before eating: Alendronate should be taken first thing in the morning on an empty stomach to maximize absorption.
C. Drink 8 oz. of water with each tablet: Take with a full glass of water to help the tablet reach the stomach and reduce esophageal irritation.
D. Avoid lying down after taking this medication: Remain upright for at least 30 minutes after dosing to prevent esophageal reflux/irritation and improve safety.
E. Take the medication with an antacid if heartburn occurs: Antacids/food decrease bisphosphonate absorption and are not recommended immediately with the dose.
Correct Answer is B
Explanation
A. "Drink a glass of water before taking your medications.": Drinking water before inhalation is not the primary preventive step for thrush.
B. "Rinse your mouth after using your inhaler medications.": Rinsing and spitting after inhaled corticosteroids (fluticasone) reduces residual steroid in the oropharynx and lowers the risk of oropharyngeal candidiasis.
C. "Wait at least one minute before taking the next medication.": Waiting between puffs of bronchodilator doses is appropriate, but this instruction doesn’t specifically prevent thrush from inhaled steroids.
D. "Close your mouth tightly around the inhaler.": Proper inhaler technique varies by device; while a good seal is important for some inhalers, it does not replace rinsing to prevent candidiasis.
