Welcome to your 🥣 Dysphagia, Plummer–Vinson Syndrome & Pharyngeal Pouch Arena — 40 Integrated MCQs
1.
A patient with a large pharyngeal pouch develops recurrent coughing after regurgitation of retained food. Which complication is of greatest concern?
2.
A 76-year-old man has progressive dysphagia, halitosis and repeated regurgitation of undigested food. Which anatomical-pathophysiological sequence best explains his condition?
3.
A 51-year-old woman with long-standing iron deficiency has dysphagia. Contrast imaging demonstrates a thin membrane projecting into the upper esophageal lumen. Iron replacement improves her anemia, but significant swallowing difficulty persists. What is the most appropriate next management principle?
4.
Which investigation is particularly useful for demonstrating the size and outline of a pharyngeal pouch?
5.
A child accidentally swallows a coin that becomes impacted in the upper esophagus. At which site is impaction particularly common?
6.
A patient has intermittent difficulty swallowing both solids and liquids from the beginning of symptoms. Which type of disorder is most likely?
7.
Which nutritional abnormality is most strongly associated with Plummer–Vinson syndrome?
8.
A 74-year-old man has dysphagia, nocturnal coughing and regurgitation of food eaten several hours earlier. A posterior hypopharyngeal outpouching is demonstrated on contrast study. Which mechanism best explains the respiratory symptoms?
9.
A Zenker diverticulum develops through a weak area in the posterior pharyngeal wall. Which anatomical site is involved?
10.
A patient arrives after corrosive ingestion with oral burns but no obvious respiratory distress. Which statement best guides assessment of the esophageal injury?
11.
A patient sustains significant mucosal injury from an esophageal foreign body that remains impacted for a prolonged period. Several weeks after removal, progressive swallowing difficulty develops. Which tissue response most likely produced this problem?
12.
A patient presents after swallowing a metallic foreign body. Which initial investigation is useful for locating a radiopaque object?
13.
A child is brought to the emergency department after swallowing a button battery that is lodged in the esophagus. What is the most appropriate management principle?
14.
A patient initially has difficulty swallowing solid food but later develops difficulty swallowing liquids as well. Which mechanism best explains this pattern?
15.
A patient presents after swallowing a sharp bone. Plain radiography does not clearly identify the object, but severe localized chest pain raises concern for esophageal wall injury. Which investigation is most useful for evaluating a possible deep complication?
16.
A patient recovers from significant corrosive injury to the esophagus but develops progressive dysphagia several weeks later. Which complication best explains the new symptoms?
17.
A patient with an impacted thoracic esophageal foreign body develops fever, severe retrosternal pain and systemic deterioration. Perforation is suspected. Which complication is most concerning?
18.
A 58-year-old man develops sudden dysphagia after a food bolus becomes impacted in the esophagus. After successful removal, the ENT team recommends further evaluation rather than assuming the event was isolated. What is the main reason for this approach?
19.
A patient presents immediately after accidental ingestion of a strong corrosive substance and has hoarseness with increasing stridor. Which issue requires first priority?
20.
A 29-year-old adult develops sudden dysphagia after eating meat. He can breathe normally but cannot swallow saliva. What feature makes this presentation require prompt endoscopic assessment rather than routine observation?
21.
An elderly patient with a suspected pharyngeal pouch is referred for endoscopic evaluation. Why must instrumentation be performed with particular care?
22.
During normal swallowing, relaxation of which structure allows the bolus to pass from the pharynx into the esophagus?
23.
A patient has swallowed a strong corrosive substance. Which action should be avoided because it may re-expose the upper gastrointestinal tract to the chemical?
24.
A 68-year-old man can chew normally, but immediately after attempting to swallow water he coughs, develops a wet voice and requires repeated attempts to clear his throat. Which physiological disturbance best explains these findings?
25.
A patient recovers from the acute phase of severe corrosive esophageal injury. Two months later, swallowing becomes progressively more difficult. Which sequence best explains this delayed complication?
26.
A patient with Plummer–Vinson syndrome has dysphagia mainly for solid food. Which structural abnormality is responsible?
27.
A patient with severe corrosive ingestion develops intense chest pain and systemic toxicity. Deep mural injury and perforation are suspected. Which investigation is most useful for assessing injury beyond the mucosal surface?
28.
A 45-year-old woman presents with dysphagia, pallor and spoon-shaped nails. Investigation demonstrates an upper esophageal web. Which diagnosis is most likely?
29.
Which functional abnormality contributes most directly to formation of a pharyngeal pouch?
30.
A patient undergoing assessment for dysphagia is suspected to have an esophageal motility disorder. Endoscopy shows no obstructing lesion. Which investigation would best assess the suspected functional abnormality?
31.
A young adult accidentally ingests a strong acidic substance. A student is asked to compare the characteristic tissue effect with strong alkali exposure. Which process is more closely associated with acid injury?
32.
A symptomatic pharyngeal pouch is treated surgically. Which procedure addresses the abnormal upper esophageal sphincter resistance contributing to pouch formation?
33.
A 62-year-old man reports difficulty initiating swallowing and coughs immediately after drinking water. Which type of swallowing disorder is most likely?
34.
A 70-year-old man has dysphagia, halitosis and regurgitation of undigested food several hours after eating. Which diagnosis is most likely?
35.
A woman previously treated for Plummer–Vinson syndrome develops progressively worsening dysphagia and weight loss after a period of clinical improvement. Which action is most appropriate?
36.
A patient with corrosive ingestion is hemodynamically stable after initial assessment. The clinical team wants to determine the extent of mucosal injury to guide further treatment. Which investigation has the most direct role?
37.
A patient undergoes treatment for a symptomatic Zenker diverticulum. The surgeon explains that correction of the underlying functional abnormality is important to reduce abnormal pressure during swallowing. Which procedure directly addresses this mechanism?
38.
A child accidentally drinks a strong alkaline cleaning fluid. Endoscopic assessment later demonstrates deep esophageal tissue injury. Which pathological mechanism best accounts for the depth of injury?
39.
A relative attempts to give an alkaline solution to a patient who has swallowed a strong acid, believing that the two chemicals will neutralize each other. Why is this approach inappropriate?
40.
A patient with Plummer–Vinson syndrome requires follow-up because of increased risk of which malignancy?
