Why are antacids administered regularly to patients experiencing acid indigestion?
A
To stimulate the secretion of bile from the liver
B
To prevent the absorption of nutrients in the stomach
C
To neutralize excess stomach acid and provide continuous relief from symptoms
D
To increase the production of stomach acid for better digestion
Verified step by step guidance1
Understand the role of antacids: Antacids are substances that neutralize excess stomach acid, which is primarily hydrochloric acid (HCl).
Recognize the cause of acid indigestion: Acid indigestion occurs when there is too much acid in the stomach, causing discomfort and symptoms like heartburn.
Explain why regular administration is needed: Since the stomach continuously produces acid, a single dose of antacid may only provide temporary relief. Regular doses help maintain a neutral pH in the stomach over time.
Clarify the mechanism of action: Antacids react chemically with the excess HCl in the stomach to form water and neutral salts, reducing acidity and soothing the stomach lining.
Eliminate incorrect options: Antacids do not stimulate bile secretion, prevent nutrient absorption, or increase stomach acid production; their primary function is to neutralize acid and relieve symptoms.
