## 문제

A postpartum nurse is assessing a breastfeeding mother on her second day after delivery. Which assessment finding would be the most important indicator of successful breastfeeding establishment?

## 보기

1. The infant demonstrates effective latch with audible swallowing sounds during feeding sessions **✔ 정답**
2. The mother reports feeling confident about her breastfeeding technique during sessions
3. The infant sleeps for 4-5 hours between feeding sessions after nursing
4. The mother's breasts feel softer after each feeding session with the infant

**정답: 1**

## 해설

Effective latch with audible swallowing indicates proper milk transfer, the most objective sign of successful breastfeeding. Other options (maternal confidence, long sleep intervals, softer breasts) are less reliable indicators in early postpartum.

## 심화 해설

Clinical Judgment
This question assesses the ability to identify the most objective and reliable indicator for evaluating the success of early postpartum breastfeeding. The key is understanding the definition of 'successful breastfeeding establishment.' This does not simply mean latching onto the breast, but rather that the newborn is effectively consuming a sufficient amount of breast milk. The 'audible swallowing sound' in option 1 is direct evidence that the newborn is actually swallowing milk, indicating that proper latch and effective milk transfer are occurring. The other options are secondary or may even indicate problems.

Memory Tip:
**A**udible **S**wallowing = **A**ssured **S**uccess. The sound of swallowing gives you assurance of success. Or remember it as "**L**atch & **S**wallow = **L**ooks **S**uccessful."

KR vs US:
In Korea, postpartum care centers tend to focus on quantitative indicators such as newborn weight gain or the number of bowel movements. In the US NGN/CJMM, while these objective indicators are also important, the direct behavioral sign (Audible swallowing) of the newborn is emphasized as the most crucial immediate assessment tool, especially during the early evaluation period (e.g., postpartum day 2). This is because it enables immediate intervention (e.g., latch correction) through the nurse's clinical judgment.

## 임상 시나리오

Clinical Practice Guide
When evaluating breastfeeding, the nurse should comprehensively assess the following:
1.  Latch: The infant should open the mouth wide, take in a substantial portion of the areola, and the lips should be flanged outward.
2.  Audible swallow: A regular "kah" sound should be heard within a few minutes after feeding begins.
3.  Breast changes: It is normal for the breasts to feel softer after feeding, but this may not be obvious initially as milk production is not yet fully established.
4.  Newborn patterns: Initially, feeding every 1-3 hours, at least 8-12 times per day, is typical; sleeping continuously for 4-5 hours may be a sign of inadequate feeding.

Caution:
In a SATA (Select All That Apply) question asking for "indicators of successful breastfeeding," both option 1 (Effective latch with audible swallowing) and option 4 (Mother's breasts feel softer) can be correct answer candidates. However, in a single-select question like this one that asks for the "**most important**" indicator, you must choose the direct behavioral evidence from the newborn (option 1). The mother's subjective report (confidence) or excessive sleep in the newborn are traps that can be interpreted as warning signs instead.

## 핵심 개념

- **Latch (젖물림)** — The way a newborn latches onto the breast. An effective latch involves taking in not just the nipple but a significant portion of the areola into the mouth, allowing for efficient milk extraction.
- **Audible Swallowing (들리는 삼키는 소리)** — A soft "kah" or "ah" sound made by a newborn when swallowing milk regularly during breastfeeding. This is the most direct objective evidence that breast milk is being effectively transferred.
- **Milk Transfer (젖 전달)** — The process of breast milk moving effectively from the breast into the newborn's mouth. This is confirmed by proper latch and swallowing.
- **Postpartum (산후기)** — The 6-week period after childbirth. The first 2-3 days of this period are a very important time for establishing breastfeeding.
- **Primigravida (초산모)** — A woman in her first pregnancy. Since she has no breastfeeding experience, education and support are especially important for her.
