## 문제

A nurse is conducting a comprehensive physical assessment on a 45-year-old client admitted with chest pain. Which assessment technique should the nurse use FIRST when examining the client's abdomen?

## 보기

1. Palpation to identify masses and organ enlargement
2. Percussion to determine organ borders and detect fluid
3. Auscultation to assess bowel sounds and vascular bruits
4. Inspection to observe contour, symmetry, and visible abnormalities **✔ 정답**

**정답: 4**

## 해설

Inspection should always be performed first in abdominal assessment to observe visible abnormalities before other techniques alter findings. Palpation, percussion, and auscultation follow in a specific sequence to ensure accurate data.

## 심화 해설

Correct Answer: 4. Inspection to observe contour, symmetry, and visible abnormalities

The correct sequence for abdominal assessment is inspection, auscultation, percussion, and then palpation. The rationale for this specific order is to prevent altering bowel sounds before they are assessed. Percussion and palpation stimulate the bowel and can artificially increase peristalsis, which would lead to inaccurate auscultation findings if performed first . The physical examination (PE) is a systematic process that relies on a logical sequence of techniques to build clinical reasoning, moving from the least invasive and most observational method to hands-on manipulation [1,2].

Inspection, the first step, allows the nurse to gather visible data without touching the patient. This includes noting the contour (flat, rounded, scaphoid, or protuberant), symmetry, skin color, scars, visible masses, or pulsations. This initial visual survey establishes a baseline and can immediately point toward specific hypotheses, such as ascites or a bowel obstruction, which then guides the subsequent, more focused examination . The development of competent PE skills in nursing students requires this structured, stepwise approach to ensure that critical findings are not missed or misinterpreted due to a flawed sequence [2,4]. Following a consistent "head-to-toe" or regional framework, where the order of techniques is standardized, reduces cognitive load and helps the examiner correctly interpret the clinical significance of each finding [1,4]. By starting with inspection, the nurse is applying the foundational principle of moving from observation to physical manipulation, a core element of safe and effective health assessment [2,4].

Clinical Practice Guide

The standard sequence for abdominal assessment is **inspection, auscultation, percussion, palpation**. This order is critical because percussion and palpation can stimulate peristalsis, altering bowel sounds and leading to inaccurate auscultation findings.

- **Inspection:** Observe the abdomen for contour, symmetry, distention, scars, visible masses, and skin changes. Perform this from the foot of the bed and at eye level.

- **Auscultation:** Use the diaphragm of the stethoscope to listen for bowel sounds in all four quadrants before any manipulation. Also listen for vascular bruits over the aorta and renal arteries.

- **Percussion:** Percuss to assess organ size, detect fluid (shifting dullness), and identify areas of tympany or dullness.

- **Palpation:** Perform light palpation first to assess for tenderness and guarding, followed by deep palpation to identify masses or organ enlargement. Always palpate the area of reported pain last.

This systematic approach ensures that critical findings are not missed or misinterpreted due to a flawed sequence, supporting accurate clinical reasoning and patient safety.

## 핵심 개념

- **Inspection** — The first step of a physical examination involving concentrated watching to gather visible data such as contour, symmetry, and skin abnormalities.
- **Auscultation** — Listening to sounds within the body, typically with a stethoscope; in abdominal assessment, it follows inspection to hear unaltered bowel sounds.
- **Percussion** — Tapping on a surface to determine the underlying structure by evaluating the sounds produced; performed after auscultation in the abdomen.
- **Palpation** — Using hands to feel body parts; the final step in abdominal assessment to avoid stimulating peristalsis and altering bowel sounds.
