26
What are typical symptoms of GERD?**
A) Fever and chills
B) Acne and hair loss
C) Heartburn and acid regurgitation
D) Nasal congestion and sneezing
*Answer:** C) Heartburn and acid regurgitation
**Rationale:** Heartburn and acid regurgitation are classic symptoms of GERD due to reflux of stomach acid into the esophagus.
27
Which of the following is an atypical symptom of GERD?**
A) Sore throat
B) Itching skin
C) Swollen joints
D) Blurred vision
Answer:** A) Sore throat
**Rationale:** Sore throat is considered an extraesophageal symptom of GERD due to acid irritating the throat.
28
GERD symptoms are often worsened by which activity?**
A) Sitting quietly
B) Bending or lying down
C) Drinking water
D) Walking outside
Answer:** B) Bending or lying down
**Rationale:** Bending or lying down can exacerbate GERD symptoms by allowing stomach acid to more easily travel up into the esophagus.
29
What pathophysiological process primarily causes GERD symptoms?**
A) Increased production of saliva
B) Contact of stomach acid with esophageal mucosa
C) Hypertrophy of esophageal sphincter
D) Oxygen deprivation of gastric mucosa
Answer:** B) Contact of stomach acid with esophageal mucosa
**Rationale:** GERD symptoms are caused by stomach acid coming into contact with the esophageal lining, which is less resistant to acid than the stomach lining.
30
Which condition is often associated with severe GERD due to structural changes at the gastroesophageal junction?**
A) Appendicitis
B) Hiatal hernia
C) Diverticulitis
D) Crohn's disease
nswer:** B) Hiatal hernia

31
What physical exam finding may suggest chronic GERD in a patient?**
A) Normal dental examination
B) Epigastric tenderness and dental erosions
C) Swollen lymph nodes in the neck
D) Rash on the abdomen
Answer:** B) Epigastric tenderness and dental erosions
**Rationale:** Epigastric tenderness can indicate underlying gastroesophageal issues, and dental erosions, especially on the back of the teeth, are associated with chronic exposure to stomach acid, suggestive of GERD.
32
Which of the following is part of the initial diagnostic approach for GERD if the PPI test is not enough?**
A) Complete blood count (CBC)
B) Esophagogastroduodenoscopy (EGD) with biopsy
C) Liver function tests
D) Urinalysis
Answer:** B) Esophagogastroduodenoscopy (EGD) with biopsy
**Rationale:** If a patient fails the PPI challenge, an EGD is performed to visualize the esophagus, stomach, and the initial part of the small intestine. This is more definitive for diagnosing GERD conditions if simpler methods, like the PPI test, are ineffective.
33
What is the first-line pharmacological treatment recommended for GERD in many cases?**
A) Antacids
B) Histamine 2 (H2) blockers
C) Proton pump inhibitors (PPIs)
D) Antibiotics
Answer:** C) Proton pump inhibitors (PPIs)
**Rationale:** PPIs are the most effective at reducing stomach acid production for treating GERD and have better efficacy in healing both erosive and non-erosive esophagitis compared to H2 blockers or antacids.
34
Which potential side effect is associated with long-term use of PPIs?**
A) Increased risk of gastrointestinal infections
B) Hypertension
C) Hair loss
D) Yellowing of the skin
Answer:** A) Increased risk of gastrointestinal infections
**Rationale:** Long-term use of PPIs can increase the risk of gastrointestinal infections (such as C. difficile) and has potential other risks such as hypomagnesemia, hip fractures, vitamin B12 deficiency, and pneumonia due to reduced stomach acid defenses.
35
Why might a patient on PPIs need H2 blockers as adjunct therapy?**
A) To control symptoms related to blood pressure fluctuations
B) To provide additional symptom relief at bedtime
C) To increase histamine levels
D) To treat concurrent viral infections
Answer:** B) To provide additional symptom relief at bedtime
**Rationale:** H2 blockers can be used in conjunction with PPIs to provide additional acid suppression overnight if symptoms persist, as the basal acid secretion increases at night.
36
What is considered the first phase of a step-wise approach to managing GERD?**
A) Immediate surgical intervention
B) Endoscopic examination
C) Lifestyle and diet modifications, along with antacids, H2 blockers, or PPIs
D) Chemotherapy
Answer:** C) Lifestyle and diet modifications, along with antacids, H2 blockers, or PPIs
**Rationale:** The initial management of GERD involves non-invasive measures such as lifestyle and dietary changes and the use of antacids or acid suppression medications like H2 blockers and PPIs to manage symptoms. This conservative approach is preferred before progressing to more invasive measures.
37
Under which circumstance should a patient with GERD be considered for surgical intervention?**
A) After 2 weeks of PPI treatment with persistent symptoms
B) Only if lifestyle changes effectively manage symptoms
C) When symptoms persist despite optimal medical therapy including PPIs, and possibly after endoscopic evaluation
D) As the first-line treatment for all GERD cases
Answer:** C) When symptoms persist despite optimal medical therapy including PPIs, and possibly after endoscopic evaluation
**Rationale:** Surgical options, such as laparoscopic fundoplication, are considered only when other treatments such as PPIs fail to control symptoms, and any relevant endoscopic evaluations indicate the need.
38
Which is an appropriate follow-up action if a patient's GERD symptoms do not improve after 8 weeks of PPI treatment?**
A) Continue the same PPI regimen indefinitely without changes
B) Stop all therapies and switch to herbal remedies
C) Conduct an endoscopic evaluation and consider referring to a gastroenterologist
D) Prescribe antibiotics for potential gastrointestinal infection
*Answer:** C) Conduct an endoscopic evaluation and consider referring to a gastroenterologist
**Rationale:** Persistent symptoms despite an appropriate course of PPIs necessitate further investigation through endoscopy and potential involvement of a gastroenterologist to evaluate for complications or alternative diagnoses
39
Which surgical procedure is often preferred for GERD cases requiring intervention?**
A) Open fundoplication
B) Gastric bypass
C) Laparoscopic fundoplication
D) Colectomy
Answer:** C) Laparoscopic fundoplication
**Rationale:** Laparoscopic fundoplication is preferred over open surgery due to its minimally invasive nature, fewer complications, and quicker recovery times, making it ideal for managing GERD in surgical candidates.
40
In the management of GERD, what indicators suggest the need for an endoscopy?**
A) Excellent symptomatic response to lifestyle modifications
B) Asymptomatic presentation
C) Poor response to medical therapy or the development of new symptoms like dysphagia
D) Gradual symptom improvement with no additional complications
Answer:** C) Poor response to medical therapy or the development of new symptoms like dysphagia
