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).

During a home visit, the nurse has lined a table, placed her bag on it, washed her hands, put on her apron, taken out the articles she needs, and set a paper bag for waste outside the clean area. What should she do NEXT, before she weighs the infant?

1. Close the bag so its contents stay clean during the procedure **✔ 정답**
2. Wash her hands again before touching the infant's clothes
3. Leave the bag open in case she needs other articles later
4. Take out the thermometer as well in case it is needed later

**정답: 1**

## 해설

In bag technique, once the needed articles are out and the waste receptacle is placed, the nurse closes the bag before starting care. This keeps the bag's contents from being contaminated and prevents reopening it with soiled hands. Her hands were just washed, so she proceeds to care after closing the bag.

Bag technique during home visit

The correct action is to close the bag before proceeding to weigh the infant. In the bag technique, the nursing bag serves as a clean storage space for all articles that may be needed during the visit. Once the nurse has removed the necessary items and placed a separate receptacle for waste outside the clean area, the bag must be closed. This prevents airborne contaminants or accidental contact from soiling the remaining contents, and it also avoids the need to reach into the bag later with hands that may have become contaminated during care.

The sequence matters because the bag technique is built on the principle of maintaining a clean field within the home environment. The home is not a controlled clinical setting, so the nurse creates a temporary clean work area using the lined table and the closed bag. Closing the bag immediately after removing needed articles protects the remaining supplies from contamination and prevents the nurse from reopening it with soiled hands later in the visit. If the bag were left open, dust, droplets, or accidental contact with the infant’s clothing or the nurse’s apron could contaminate unused items.

Hand hygiene is already addressed in the scenario: the nurse washed her hands before setting up the clean area and putting on the apron. Therefore, washing hands again before touching the infant’s clothes is not the next step. The hands are considered clean at this point because hand hygiene was performed immediately before preparing the clean field and before any contact with the infant or potentially contaminated surfaces. Re-washing at this stage would interrupt the workflow without adding benefit, since no contamination has yet occurred.

The evidence from home care settings reinforces why this sequence is important. In a cross-sectional study of nursing teams during home visits, overall adherence to hand hygiene was only 14.4%, and the practice was more frequent after patient contact (53.7%) than before aseptic procedures or before touching the patient. This highlights a common gap: nurses may remember to clean their hands after care but may not consistently protect the clean field before care begins. Closing the bag before starting the procedure is a structural safeguard that compensates for lapses in hand hygiene timing, because it reduces the chance that the nurse will need to touch the bag again with contaminated hands.

Watch out! Leaving the bag open “in case other articles are needed later” is a common error in home care. It may seem convenient, but it creates a contamination risk for every unused item inside. The correct approach is to anticipate needed articles, remove them all at once, and then close the bag. If an unexpected item is needed later, the nurse must perform hand hygiene before reopening the bag.

Key point! The bag technique follows a strict order: prepare the clean area, wash hands, put on the apron, remove needed articles, set up the waste receptacle, and then close the bag. Only after the bag is closed does the nurse proceed to direct care such as weighing the infant. Taking out the thermometer “in case it is needed later” is not appropriate because it adds an unnecessary item to the clean field and does not address the immediate need to secure the bag.

The rationale for closing the bag is not only about protecting supplies; it also supports efficient workflow. A closed bag signals that the preparation phase is complete and that the nurse can now focus entirely on the infant and family. By closing the bag, the nurse establishes a clear boundary between the clean storage area and the care environment, minimizing the number of times she must interrupt care to manage equipment. This is especially relevant in home visits, where the physical environment is less predictable than a clinic or hospital room.

In summary, after the nurse has lined the table, placed the bag, washed hands, put on the apron, removed needed articles, and set the waste bag outside the clean area, the next step is to close the bag. This protects the remaining contents from contamination and prevents the need to reopen it with soiled hands during or after infant care. The hand hygiene data from home care settings underscore that environmental safeguards like closing the bag are essential when hand hygiene adherence is inconsistent.

## 임상 시나리오

Bag Technique During Home VisitProtecting clean supplies before infant care
After removing needed articles and placing the waste receptacle outside the clean area, close the nursing bag before starting care. This keeps remaining contents clean and prevents reopening with soiled hands later.

The home is not a controlled clinical setting, so the nurse creates a temporary clean field using a lined table and a closed bag. Hand hygiene was already done before setup, so proceed to care after closing the bag.

CautionDo not leave the bag open or remove extra articles such as a thermometer unless needed. Reopening the bag with contaminated hands during care risks contaminating unused supplies.

## 핵심 개념

- **Bag technique** — A home visit method using a nursing bag as clean storage; open only to remove needed items, then close to prevent contamination.
- **Clean field** — A temporary clean work area created in the home using a lined table and closed bag to separate clean from contaminated zones.
- **Waste receptacle** — A separate paper bag placed outside the clean area for soiled items during the procedure.
- **Hand hygiene** — Washing hands before setting up the clean area and before care; not repeated unnecessarily when already clean.
- **National Immunization Program** — A public health program ensuring infants and toddlers receive scheduled vaccines; relevant to RHU family contacts.
