1 What is the main treatment goal for PUD/GERD?
A Neutralization of stomach acid
B Eradication of H. pylori
C Promotion of gastric emptying
D Protection of the gastric mucosa only
Why A is correct: The main treatment goal for PUD and GERD is neutralization or reduction
of stomach acid to allow healing of mucosal damage and prevent further injury.
B — Eradication of H. pylori is important but not the main goal for all cases.
C — Promotility agents address symptoms but acid neutralization is primary.
D — Mucosal protection is supportive but not the primary goal.
