This is the final lecture of Chapter 8. In this lecture, you will combine everything you have learned into one complete abdominal assessment. This is exactly how Registered Nurses perform abdominal assessments during clinical practice, nursing school check-offs, and the NCLEX.
Today, you stop memorizing isolated facts and begin thinking like an RN.
By the end of this lecture, you should be able to:
Perform a complete abdominal assessment from start to finish.
Recognize normal and abnormal findings.
Identify common gastrointestinal disorders based on assessment findings.
Prioritize abnormal findings using nursing judgment.
Document abdominal assessments professionally.
Communicate findings using SBAR.
Answer advanced NCLEX-style questions using clinical reasoning.
You are assigned to a 65-year-old patient admitted with abdominal pain.
The patient says:
"My stomach has been hurting since yesterday."
A beginning student documents:
"Patient complains of abdominal pain."
An experienced RN immediately begins organizing the assessment:
Where is the pain?
When did it begin?
Did it move?
What does it feel like?
What makes it worse?
Associated nausea?
Vomiting?
Fever?
Bowel movement?
Passing gas?
Previous surgery?
Medications?
Inspection
Auscultation
Percussion
Palpation
The experienced nurse knows that one symptom can represent dozens of diseases.
Your assessment narrows the possibilities.
Always follow the same routine.
Consistency prevents mistakes.

Now let's develop clinical reasoning.
Patient has:
Right upper quadrant pain
Pain after fatty meals
Fever
Positive Murphy's sign
Nausea
Think.
Instead of memorizing symptoms individually, ask:
"What disease connects these findings?"
Answer:
Acute cholecystitis.
Patient has:
Pain began around umbilicus
Pain moved to RLQ
Fever
Nausea
Rebound tenderness
Positive Rovsing's sign
Think:
Appendicitis.
Patient has:
Rigid abdomen
Absent bowel sounds
Severe pain
Hypotension
Fever
Think:
Peritonitis.
This patient requires immediate intervention.
Patient has:
Hyperactive bowel sounds
Vomiting
Distended abdomen
Unable to pass gas
Cramping pain
Think:
Possible bowel obstruction.
Patient has:
Large abdomen
Bulging flanks
Generalized dullness
History of liver disease
Think:
Ascites.
Patient has:
Epigastric burning
Pain improves after eating
Nighttime pain
Think:
Duodenal ulcer.
Patient has:
Black tarry stool
Weakness
Pallor
Fatigue
Orthostatic hypotension
Think:
Upper gastrointestinal bleeding until proven otherwise.
Patient has:
Bright red blood per rectum
Normal abdomen
History of hemorrhoids
Think broadly.
Possible causes include:
Hemorrhoids
Diverticular bleeding
Lower gastrointestinal bleeding
Inflammatory bowel disease
Further evaluation is required.
Patient has:
Flank pain
Fever
Positive costovertebral angle tenderness
Think:
Pyelonephritis.
Patient has:
Generalized abdominal tenderness
Distention
Absent bowel sounds
Recent abdominal surgery
Think:
Postoperative ileus.
Every RN should immediately recognize these conditions.
Findings:
Rigid abdomen
Board-like abdomen
Severe pain
Rebound tenderness
Absent bowel sounds
Fever
Tachycardia
Hypotension
This is a surgical emergency.
Findings:
Vomiting
Distention
Cramping
Unable to pass stool
Unable to pass flatus
Hyperactive sounds early
Hypoactive or absent sounds later
Findings:
Vomiting blood
Black stool
Bright red rectal bleeding
Weakness
Pallor
Hypotension
Tachycardia
Requires immediate evaluation.
Findings:
Sudden severe abdominal pain
Back pain
Hypotension
Pulsatile abdominal mass
Shock
Do NOT palpate repeatedly.
Immediate emergency response is required.
Findings:
RLQ pain
Fever
Nausea
Loss of appetite
Positive McBurney tenderness
Positive Rovsing sign
Possible rebound tenderness
A patient has:
RUQ pain
Pain after fried foods
Positive Murphy sign
Temperature 101.8°F
Diagnosis most consistent with:
Acute cholecystitis.
A patient reports:
Black stools
Fatigue
Blood pressure 90/58
Pulse 118
Think:
Possible upper gastrointestinal bleed with signs of hypovolemia.
The nurse should recognize this as an urgent situation.
Patient:
Distended abdomen
No bowel sounds after listening for five minutes
Vomiting
Unable to pass flatus
Think:
Possible bowel obstruction or paralytic ileus.
Patient:
Rigid abdomen
Pain 10/10
Fever
Hypotension
Guarding
Think:
Peritonitis until proven otherwise.
Abdomen flat, symmetrical, and non-distended. Skin intact without lesions or scars. Umbilicus midline and inverted. Bowel sounds active in all four quadrants. Tympany predominates with expected dullness over the liver. Abdomen soft and non-tender. No guarding, rebound tenderness, organomegaly, or palpable masses. No costovertebral angle tenderness.
Abdomen distended with generalized tenderness. Bowel sounds hypoactive. Tympany decreased with diffuse dullness over the flanks. Positive fluid wave. Abdomen firm with involuntary guarding. Rebound tenderness present in the right lower quadrant. Patient reports pain 9/10. Provider notified immediately.
"I am calling regarding worsening abdominal pain."
"The patient was admitted six hours ago with abdominal pain and nausea."
"The patient now has a rigid abdomen, absent bowel sounds after five minutes of auscultation, rebound tenderness, fever of 38.9°C (102°F), heart rate of 126, and blood pressure of 88/52."
"I recommend immediate provider evaluation because I am concerned about peritonitis or another acute surgical abdomen."
Changing the examination sequence.
Skipping the health history.
Listening too briefly for bowel sounds.
Beginning palpation over the painful area.
Using excessive pressure.
Failing to recognize patterns.
Ignoring hypotension.
Ignoring abnormal stool color.
Documenting vague findings.
Failing to notify the provider about critical findings promptly.
Which assessment finding requires immediate nursing intervention?
A. Mild constipation
B. Rounded abdomen
C. Rigid abdomen with absent bowel sounds and hypotension
D. Soft, non-tender abdomen
Answer: C
Rationale: This combination suggests a surgical abdomen requiring urgent evaluation.
A patient reports pain that began around the umbilicus and later moved to the right lower quadrant. Which condition should the nurse suspect?
A. Cholecystitis
B. Appendicitis
C. Pancreatitis
D. Diverticulitis
Answer: B
Which finding is most consistent with ascites?
A. Hyperactive bowel sounds
B. Generalized abdominal dullness with bulging flanks
C. Pain only in the left lower quadrant
D. Hyperresonance throughout the abdomen
Answer: B
A patient has black, tarry stools and orthostatic hypotension. Which interpretation is most appropriate?
A. Normal iron supplementation
B. Possible upper gastrointestinal bleeding with volume loss
C. Irritable bowel syndrome
D. Viral gastroenteritis
Answer: B
Which assessment finding is expected in acute cholecystitis?
A. Positive Murphy's sign
B. Positive Rovsing's sign
C. Positive obturator sign
D. Positive psoas sign
Answer: A
Right = Liver and Gallbladder
Think:
"Right for Bile."
Right Lower = Appendix
Think:
"Right Lower, Right Appendix."
Think:
Tympany = Tummy Air
Air makes a drum-like sound.
Murphy = Gallbladder.
Think:
"Murphy Makes Me Stop Breathing."
The patient abruptly stops inhaling due to pain.
Rovsing = Right Lower Quadrant pain when the left lower quadrant is palpated.
Think:
"Left Push, Right Pain."
By now, you should be able to perform the entire abdominal assessment in this order:
Introduce yourself and identify the patient.
Perform hand hygiene.
Explain the procedure.
Position the patient supine with knees slightly flexed if needed.
Inspect the abdomen.
Auscultate bowel sounds.
Auscultate for vascular sounds.
Percuss all quadrants.
Estimate liver span.
Perform light palpation.
Perform deep palpation when appropriate.
Assess for guarding, rebound tenderness, and masses.
Perform special tests if indicated (such as Murphy's sign or assessment at McBurney's point).
Assess for costovertebral angle tenderness if kidney involvement is suspected.
Document findings clearly.
Report urgent abnormalities promptly.
Congratulations—you have completed Chapter 8: Abdomen (Gastrointestinal System).
You can now:
Perform a complete abdominal assessment using the correct sequence.
Identify normal and abnormal abdominal findings.
Distinguish tympany from dullness.
Perform light and deep palpation safely.
Assess the liver, spleen, and kidneys.
Recognize common gastrointestinal emergencies.
Apply clinical reasoning to abdominal assessment findings.
Document and communicate findings using professional nursing standards.
This chapter is one of the highest-yield topics for nursing school, clinical skills evaluations, and the NCLEX because abdominal complaints are extremely common across medical-surgical, emergency, pediatric, geriatric, and primary care settings.
