1.
What type of tissue lines the esophagus?
Correct Answer
B. Stratified squamous epithelium
Explanation
The correct answer is stratified squamous epithelium. The esophagus is a muscular tube that connects the throat to the stomach. It is constantly exposed to the friction and mechanical stress of food passing through it. Stratified squamous epithelium is a type of tissue that is well-suited for protection against abrasion and mechanical damage. It consists of multiple layers of flat cells that can withstand the wear and tear of food passage.
2.
An infant presents with excess saliva production, choking, and coughing when feeding and appears cyanotic. What is your diagnosis?
Correct Answer
B. Congenital tracheoesopHageal fistulas
Explanation
The correct answer is congenital tracheoesophageal fistulas. This condition is characterized by an abnormal connection between the trachea and the esophagus, which is present from birth (congenital). The excess saliva production, choking, and coughing when feeding are due to the abnormal communication between the two structures, which allows saliva and food to enter the airway. The cyanosis is a result of the compromised airway and inadequate oxygenation.
3.
What type of dysphagia usually arises from within the body of the esophagus, the LES, or the cardia?
Correct Answer
B. EsopHageal dyspHagia
Explanation
Esophageal dysphagia is the correct answer because it refers to difficulty swallowing that arises from within the esophagus, lower esophageal sphincter (LES), or the cardia. This type of dysphagia can be caused by various conditions such as esophageal strictures, tumors, or motility disorders that affect the movement of food through the esophagus. It is important to differentiate esophageal dysphagia from oropharyngeal dysphagia, which is difficulty swallowing that originates in the mouth or throat. Functional dysphagia and tracheoesophageal dysphagia are not the correct answers as they do not specifically relate to dysphagia arising from within the esophagus, LES, or cardia.
4.
What is it called when the events of swallowing are poorly coordinated or muscles fail to relax to allow passage of food?
Correct Answer
C. Motility dyspHagia
Explanation
Motility dysphagia refers to a condition where the events of swallowing are poorly coordinated or the muscles fail to relax, making it difficult for food to pass through. This can result in difficulties with swallowing and can be caused by various factors such as nerve damage or muscle disorders.
5.
What is it called when pain is triggered by swallowing?
Correct Answer
D. OdynopHagia
Explanation
Odynophagia is the correct answer because it refers to the condition where pain is experienced while swallowing. It is derived from the Greek words "odyne" meaning pain and "phagia" meaning swallowing. This term is commonly used in medical settings to describe the symptom of pain during swallowing, which can be caused by various underlying conditions such as infections, inflammation, or structural abnormalities in the throat or esophagus.
6.
What type of diagnostic exam permits biopsy, injection of cautery or lesions, dilation of strictures, extraction of foreign bodies?
Correct Answer
C. Endoscopy
Explanation
Endoscopy is the correct answer because it is a diagnostic exam that allows for a variety of procedures such as biopsy, injection of cautery or lesions, dilation of strictures, and extraction of foreign bodies. It involves the use of a flexible tube with a light and camera attached to it, which is inserted into the body to visualize and examine the esophagus and other parts of the digestive system. This procedure is commonly used to diagnose and treat various conditions affecting the esophagus.
7.
What type of diagnostic exam is typically performed by a speech pathologist and radiologist, and is performed by having the patient swallow a variety of foods covered with barium?
Correct Answer
C. Modified barium swallow
Explanation
A modified barium swallow is a diagnostic exam that is typically performed by a speech pathologist and radiologist. It involves having the patient swallow a variety of foods covered with barium. The barium allows the radiologist to visualize the swallowing process using X-rays, which helps in identifying any abnormalities or difficulties in swallowing. This test is commonly used to evaluate and diagnose swallowing disorders or dysphagia.
8.
What type of diagnostic exam uses a flexible tube with a probe that measures pressures in the stomach?
Correct Answer
D. EsopHageal manometry
Explanation
Esophageal manometry is a diagnostic exam that uses a flexible tube with a probe to measure pressures in the stomach. This procedure helps to evaluate the function and movement of the esophagus and lower esophageal sphincter. It is commonly used to diagnose conditions such as gastroesophageal reflux disease (GERD), achalasia, and esophageal motility disorders. By measuring the pressures in the stomach, esophageal manometry provides valuable information about the coordination and strength of the muscles involved in swallowing and digestion.
9.
What type of diagnostic exam uses hydrochloric acid and salt water to reproduce chest pain and discomfort?
Correct Answer
C. Bernstein test
Explanation
The Bernstein test is a diagnostic exam that uses hydrochloric acid and salt water to reproduce chest pain and discomfort. This test is commonly used to determine if a patient's symptoms are caused by acid reflux or other conditions. During the test, the patient swallows a small amount of acid and salt water, which can irritate the esophagus and trigger symptoms such as chest pain and discomfort. If the symptoms are reproduced, it suggests that acid reflux may be the cause.
10.
What is it called when the gastroesophageal junction and fundus of the stomach move upward?
Correct Answer
B. Sliding hiatal hernia
Explanation
A sliding hiatal hernia occurs when the gastroesophageal junction and fundus of the stomach move upward into the chest through the hiatus, which is an opening in the diaphragm. This can cause symptoms such as heartburn, regurgitation, and chest pain. It is called a sliding hernia because the stomach and esophagus slide in and out of the chest through the hiatus. It is a common condition and can be diagnosed through medical imaging tests such as an endoscopy or barium swallow. Treatment options include lifestyle changes, medications, and in severe cases, surgery.
11.
What is it called when the esophagogastric junction remains fixed in the normal position while the stomach rolls up along the lower esophagus. (stomach herniates through a diaphragmatic defect).
Correct Answer
C. ParaesopHageal hiatal hernia
Explanation
A paraesophageal hiatal hernia is when the esophagogastric junction remains in its normal position, but the stomach rolls up and herniates through a diaphragmatic defect. This is different from a sliding hiatal hernia, where the esophagogastric junction itself moves upward into the chest. Esophageal diverticula and Zencker's diverticulum are unrelated conditions and do not involve the stomach herniating through a diaphragmatic defect.
12.
What is the form of diverticulum called that is right above the UES?
Correct Answer
B. Zencker's diverticulum
Explanation
Zencker's diverticulum is a form of diverticulum that is located right above the UES (Upper Esophageal Sphincter). It is a pouch-like protrusion that forms in the wall of the esophagus, specifically in the area known as Killian's triangle. This type of diverticulum is typically caused by a dysfunction of the muscles in the area, leading to the formation of the pouch. Symptoms of Zencker's diverticulum can include difficulty swallowing, regurgitation of undigested food, and bad breath. Treatment options may include lifestyle changes, medication, or surgery, depending on the severity of the symptoms.
