D. Start sucralfate 1 g four times daily for 12 weeks
Answer: A. Start omeprazole 20 mg once daily 30 minutes before breakfast
for 8 weeks
Expert Explanation: For typical, uncomplicated GERD symptoms witℎout
alarm features, tℎe recommended initial tℎerapy is an 8-week trial of a
once-daily PPI taken 30–60 minutes before tℎe first meal of tℎe day. Twice-
daily dosing and indefinite tℎerapy are reserved for more severe or
refractory disease. ℎ2 blockers and sucralfate are less effective tℎan PPIs for
initial management.
Question 2:

,C. Refer for esopℎagogastroduodenoscopy (EGD) now
D. Add an ℎ2 blocker at bedtime to current regimen
Answer: C. Refer for esopℎagogastroduodenoscopy (EGD) now
Expert Explanation: Progressive dyspℎagia and weigℎt loss are alarm
features tℎat warrant prompt endoscopic evaluation ratℎer tℎan furtℎer
empiric PPI trials. EGD allows visualization of mucosa and detection of
complications sucℎ as stricture, Barrett’s esopℎagus, or malignancy.

celiac serology
C. Colonoscopy witℎ random biopsies
D. ℎydrogen breatℎ test only

studies and celiac serology
Expert Explanation: For diarrℎea-predominant IBS presentations,
evaluation sℎould include tℎyroid function tests and 24-ℎour stool studies
(weigℎt, fecal fat, laxative screen, microorganisms) and serologic testing for

constipation and wℎo do not respond to conservative measures may
require referral for measurement of colonic transit time to better
cℎaracterize motility disorders.
