## 문제

Situation: The public health nurse of a Rural Health Unit (RHU) plans her week of contacts with registered families. Many are young families whose infants and toddlers are healthy and whose immunizations are up to date under the National Immunization Program (NIP).

After finishing care in one home, the nurse must complete these bag technique steps:
1. Wash her hands
2. Clean and disinfect the used articles
3. Return the articles to their places in the bag
4. Fold the lining and place it back in the bag
In what order should she do them?

## 해설

Used articles are cleaned and disinfected first, because handling them soils the hands. The nurse then washes her hands so that clean hands return the clean articles to the bag. The lining is folded and put back last, just before the bag is closed.

## 심화 해설

The correct sequence is 2, 1, 3, 4: clean and disinfect used articles first, then wash hands, then return articles to the bag, and finally fold and replace the lining.

Why cleaning comes before handwashing

In the bag technique, the overriding principle is preventing transfer of infection between the home, the nurse, and the bag. After a home visit, any article that touched the client or the home environment is considered contaminated. If the nurse touches those used articles and then washes her hands, the articles remain soiled and would re-contaminate clean hands the moment she picks them up again. Therefore, the used articles must be cleaned and disinfected first. This step removes or reduces the microbial load on the articles themselves, so that subsequent handling does not spread organisms.

Once the articles are clean, the nurse’s hands are still contaminated from having handled the soiled items during cleaning. Handwashing at this point removes that contamination. The logic is sequential: dirty hands are washed only after the dirty objects have been made safe, so that clean hands do not touch dirty objects again.

Why returning articles comes after handwashing

After handwashing, the nurse’s hands are clean. Only clean hands should reach into the bag to place articles back in their designated spots. If the nurse returned the articles before washing her hands, she would transfer organisms from her hands onto the bag interior, the remaining supplies, and the lining. This would turn the bag itself into a reservoir for cross-contamination to the next family visited.

Why the lining is folded and replaced last

The lining functions as a clean barrier inside the bag. It should be handled only with clean hands and only after all contaminated items have been cleaned and returned. Folding and placing the lining back is the final step because it seals the clean environment just before the bag is closed. If the lining were handled earlier, it could become contaminated by contact with soiled articles or unwashed hands.

Key point! The sequence follows the principle of working from the most contaminated to the least contaminated: soiled articles are made safe first, hands are cleansed next, clean hands handle clean articles, and the clean lining is placed last to protect the bag interior.

Watch out! A common error is to wash hands first because handwashing feels like the most basic step. However, washing hands before cleaning the used articles means the nurse would then touch contaminated articles with clean hands, requiring a second handwashing. The correct order avoids this redundancy and maintains a one-way flow from dirty to clean.

The bag technique may vary in specific steps depending on agency policy or the home situation, but the underlying principle of avoiding infection transfer remains constant. The order of cleaning, then handwashing, then returning articles, then replacing the lining reflects that principle most directly.

Bag Technique After Home VisitPreventing Cross-Contamination
The correct sequence is 2, 1, 3, 4: clean and disinfect used articles first, then wash hands, then return articles to the bag, and finally fold the lining.

Cleaning before handwashing ensures that contaminated articles do not re-soil clean hands. After cleaning, handwashing removes organisms picked up from the soiled items, so only clean hands reach into the bag.

CautionNever return used articles to the bag before handwashing. This transfers organisms onto the bag interior, remaining supplies, and the lining, compromising the entire bag technique.
