NURS_305: Gastrointestinal Disorders Exam Prep Questions
and Answers with Detailed Rationales
Course Code: NURS_305
Course Name: Gastrointestinal Disorders: Pathophysiology, Diagnostics, and
Management for Nursing
Topic: Gastrointestinal System Assessment, Pathophysiology, and Clinical
Management
Academic Year: 2026/2027
,1. What is the primary objective of performing a comprehensive gastrointestinal
assessment in a clinical setting?
A. To diagnose the medical condition independently of the provider.
B. To collaborate with the interdisciplinary team and prioritize evidence-
based care for patients.
C. To replace the diagnostic laboratory workup for acute abdominal presentations.
D. To manage medication administration profiles without interdisciplinary input.
CORRECT ANSWER: B
RATIONALE: The primary goal of a nursing gastrointestinal assessment is to
gather objective and subjective clinical data to collaborate effectively with the
healthcare team and design evidence-based interventions. Nurses do not
independently diagnose medical conditions (A), nor can clinical assessment
replace laboratory or imaging diagnostics (C). Nursing care always requires
collaborative coordination, making (D) incorrect.
2. A nurse is evaluating a patient with suspected gastrointestinal bleeding and
infection. Which laboratory test is the priority to check for anemia and infectious
processes?
A. Prothrombin time (PTT)
B. Complete Blood Count (CBC)
C. Aspartate aminotransferase (AST)
D. Serum Amylase
CORRECT ANSWER: B
RATIONALE: A Complete Blood Count (CBC) evaluates hemoglobin and
hematocrit levels to detect anemia caused by gastrointestinal blood loss, while the
white blood cell (WBC) count identifies an infectious process. PTT measures
clotting cascades (A). AST reflects liver injury (C), and amylase indicates
pancreatic inflammation (D).
3. The nurse checks the Prothrombin time (PTT) test for a patient with severe
hepatic cirrhosis. What is this test evaluating?
A. Clotting times
B. Liver enzyme leakage
C. White blood cell count
D. Pancreatic auto-digestion
, CORRECT ANSWER: A
RATIONALE: The Prothrombin time (PTT) test evaluates the coagulation
pathway and clotting times. The liver synthesizes clotting factors, and a
compromised liver prolongs clotting times. It does not measure enzyme leakage
(B), immune cell counts (C), or pancreatic functioning (D).
4. A patient presents with jaundice, right upper quadrant pain, and dark urine.
Which enzymes will be significantly elevated if the patient has a liver disorder
such as hepatitis or cirrhosis?
A. Amylase and Lipase
B. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT)
C. Blood Urea Nitrogen (BUN) and Creatinine
D. Alkaline phosphatase and troponin
CORRECT ANSWER: B
RATIONALE: Aspartate aminotransferase (AST) and alanine
aminotransferase (ALT) are intracellular enzymes found in high concentrations
within hepatic tissue. When hepatocytes are damaged by inflammation, hepatitis,
or cirrhosis, these enzymes leak into systemic circulation. Amylase and lipase
evaluate pancreatitis (A). BUN and creatinine track renal health (C). Troponin is
specific to myocardial injury (D).
5. A patient is admitted with severe, boring epigastric pain that radiates to the back.
The nurse expects the provider to order tests for which enzymes to check for acute
pancreatitis?
A. Amylase and Lipase
B. AST and ALT
C. Bilirubin and Ammonia
D. Alkaline Phosphatase and LDH
CORRECT ANSWER: A
RATIONALE: Amylase and Lipase levels are primary biomarkers that
indicate inflammation and injury to the pancreas, such as acute or chronic
pancreatitis. AST and ALT track hepatic parenchymal disease (B). Ammonia
evaluates liver clearance capacity (C). Alkaline phosphatase is largely tied to
biliary tract obstruction or bone conditions (D).
, 6. A nurse is preparing a client with a history of severe dysphagia for an outpatient
diagnostic workup. Which diagnostic modality is specifically indicated to evaluate
swallowing mechanisms and structural dysphagia?
A. Endoscopic Retrograde Cholangiopancreatography (ERCP)
B. Barium Studies
C. Esophagogastroduodenoscopy (EGD)
D. Stool antigen testing
CORRECT ANSWER: B
RATIONALE: Barium Studies (such as a barium swallow) provide real-time
fluoroscopic visualization of the esophagus while swallowing a contrast agent,
making it the preferred initial tool to evaluate structural and functional dysphagia.
ERCP explores biliary and pancreatic ducts (A). EGD provides direct visual
mucosal exam but is more invasive (C). Stool testing does not evaluate swallowing
(D).
7. The nurse is explaining an upcoming Esophagogastroduodenoscopy (EGD) to a
newly admitted patient. How should the nurse define the scope of this procedure?
A. A radiographic exam of the liver, gallbladder, bile ducts, and pancreas.
B. A visual exam of the esophagus, stomach, and duodenum.
C. A contrast-enhanced fluoroscopic scan of the entire lower colon.
D. An ultrasound-guided biopsy of the gastric muscular layer.
CORRECT ANSWER: B
RATIONALE: An Esophagogastroduodenoscopy (EGD) is an invasive
diagnostic procedure that provides a visual exam of the esophagus, stomach, and
duodenum via a flexible fiberoptic endoscope. Radiographic assessment of the
biliary tree describes an ERCP (A). A colon scan (C) and gastric ultrasound-guided
biopsy (D) represent separate diagnostic modalities.
8. To ensure safety and prevent aspiration during an EGD, the nurse must instruct
the patient to maintain which dietary restriction before undergoing the procedure?
A. Clear liquids only for 24 hours prior.
B. NPO for 6–8 hours prior to the procedure.
C. High-protein meal 2 hours before the insertion.
D. Fluid restriction for 48 hours.
