Sample question 1

A 70-year-old woman presents with chronic constipation for the past year, reporting fewer than 3 bowel movements per week. She strains frequently and often feels incomplete evacuation. She drinks adequate fluids, eats a high-fiber diet (25 g daily), and walks 30 minutes daily. She takes calcium carbonate for osteoporosis and occasional acetaminophen. She has no alarm symptoms such as rectal bleeding, weight loss, or change in stool caliber. What is the most appropriate first-line pharmacologic therapy?

  1. Prescription prokinetic agent (prucalopride) as initial therapy
  2. Osmotic laxative such as polyethylene glycol (PEG 3350)
  3. Daily stimulant laxative (bisacodyl) as first-line therapy
  4. Opioid antagonist (methylnaltrexone)

Sample question 2

A 4-year-old girl is brought in for evaluation of infrequent, hard, painful stools occurring every 4-5 days for the past 3 months. She occasionally has streaks of bright red blood on the stool surface. She withholds stool by stiffening her legs and crossing them. Her abdomen is soft with a palpable stool mass in the left lower quadrant. Growth parameters are normal. What is the most appropriate initial treatment?

  1. Polyethylene glycol 3350 (MiraLAX) daily with dietary and behavioral modifications
  2. Mineral oil enema followed by daily stimulant laxative
  3. Referral for colonoscopy to evaluate rectal bleeding
