In what order do you assess the abdomen Why?

Chapter 5 – Gastrointestinal System

Abdominal assessment involves inspection, auscultation, palpation, and percussion. This order of physical assessment is important to preserve normal bowel sounds when auscultating. For example, pressing on the abdomen can modify bowel sounds by increasing peristalsis (wave-like contractions of the intestines).

Before beginning, ask the client to empty their bladder and bowel so that fullness will not influence the findings. 

This assessment is best accomplished in the supine position because this allows any air in the abdominal region to rise to the surface area. The client should lie flat with their head on a pillow. Some clients may find it difficult to lie completely flat; if so, you can slightly elevate the head of the bed (about 10 degrees). To ensure the abdominal musculature is relaxed, ask the client to have their arms resting beside their body and their knees bent with either their feet placed flat on the bed or a pillow placed under their knees. For a newborn or young child, you can ask someone (care partner, parent, healthcare provider) to hold them on their lap. 

Always do the assessment on bare skin.

Contextualizing Inclusivity – Discomfort in Exposing Abdomen

Some clients are uncomfortable exposing their abdomen. For example, they may feel uncomfortable because of body image issues associated with weight, modesty related to cultural or religious beliefs, or a new ostomy such as a colostomy or an ileostomy. Ostomies are surgically created openings onto the abdomen that allow stool to bypass a damaged/diseased part of the intestine and leave the body.

It is important that you create an inclusive environment that is judgment free and recognizes the client’s potential discomfort. For example, you may begin the assessment with the following: “I need to assess your abdomen on the bare skin. Is that okay?” (wait for the client to give consent).

What is the correct order for abdominal assessment?

A. Inspection, palpation, auscultation, percussion
B. Inspection, auscultation, percussion, palpation
C. Auscultation, inspection, palpation, percussion
D. Palpation, inspection, auscultation, percussion

Summary

A fundamental part of physical examination is examination of the abdomen, which consists of inspection, auscultation, percussion, and palpation. The examination begins with the patient in supine position, with the abdomen completely exposed. The skin and contour of the abdomen are inspected, followed by auscultation, percussion, and palpation of all quadrants. Depending on the findings or patient complaints, a variety of examination techniques and special maneuvers can provide additional diagnostic information.

Suggested sequence

Auscultation of the abdomen should be performed prior to percussion and palpation, as physical manipulation of the abdomen may induce a change in bowel sounds.

Palpation of the abdomen

  • Purpose: to evaluate internal organs and identify any sources of pain (if present)
  • Prior to palpation, ask the patient whether they have abdominal pain or tenderness. If so, begin palpation in the non-painful area.
  • Observe the patient's face during abdominal palpation, as it is the main indicator of the intensity and location of pain.
  • Procedure:
    1. Superficial palpation: to assess for superficial or abdominal wall processes
    2. Deep palpation in all four quadrants: to assess intraabdominal organs (potential signs of peritonitis)
      • Rebound tenderness: abrupt increase in pain when an examiner suddenly releases compression of the abdominal wall. Caused by irritation of the receptors in parietal peritoneum
      • Abdominal guarding: patient contraction of the abdominal wall muscles during palpation
    3. Palpation of the liver
      • Place the pads of your fingers over the right upper quadrant, approx. 10 cm below the costal margin at the mid-clavicular line. Palpate as you move towards the right upper quadrant and attempt to feel for the edge of the liver. Continue until you feel the liver or reach the costal margin.
      • Asking the patient to take a deep breath may facilitate palpation of the liver, as the movement of the diaphragm will move the liver toward your hand.
    4. Palpation of the spleen
      • Place the pads of your fingers lateral to the belly button and palpate as you move towards the left upper quadrant. Repeat 10 cm below the left costal margin.
      • Asking the patient to lie on their right side may facilitate palpation of an enlarged spleen.
    5. Palpation of the inguinal lymph nodes: (see examination of the lymph nodes)

Abdominal tenderness may be a sign of numerous conditions (see differential diagnosis of acute abdomen and differential diagnoses of abdominal pain).

Special tests

  • Fluid wave test or shifting dullness for ascites
  • CVA tenderness for diagnostic evaluation of the kidney and urinary tract
  • Murphy sign for acute cholecystitis
  • Signs of appendicitis
  • Digital rectal examination: to assess for rectal bleeding, fecal impaction, colorectal cancer, and/or to evaluate the prostate
