## 문제

Situation: A nurse at a lying-in clinic prepares mothers and their healthy term newborns for discharge and follows them up by telephone and home visits during the first weeks after birth.

On a home visit, the nurse finds that the family of a 1-week-old girl sleeps together on a mat on the floor and has no crib. What should the nurse teach?

## 보기

1. Lay her on a soft pillow on the family mat to raise her head
2. Lay her on her side, with a rolled blanket behind her back
3. Let her sleep between the parents on the family mat to keep her warm
4. Lay her on her back on a separate firm, flat mat beside the parents **✔ 정답**

**정답: 4**

## 해설

When no crib is available, the infant should have a separate, firm, flat sleep surface close to the parents, with no soft bedding. She is always placed on her back. Sleeping between adults, side-lying, and pillows all raise the risk of suffocation and sudden infant death.

## 심화 해설

Clinical context

A home visit for a 1-week-old term newborn reveals a floor-mat sleeping arrangement with no crib. The teaching must preserve safe infant sleep while respecting the family’s current resources and cultural sleeping pattern.

Core principle

The infant needs a separate, firm, flat sleep surface placed close to the parents. The newborn is always positioned supine. Soft pillows, rolled blankets behind the back, and bed-sharing between adults all increase the risk of suffocation and sudden unexpected infant death (SUID).

Why option 4 is correct

Laying the infant on her back on a separate firm, flat mat beside the parents satisfies the three core safe-sleep elements: supine position, firm nonshared surface, and proximity to caregivers without sharing the same sleep surface. The American Academy of Pediatrics recommendation described in the surveillance data is that infants sleep supine on a flat, firm, nonshared surface without soft bedding [3]. A firm mat can function as that surface when a crib is unavailable, as long as it is dedicated to the infant and kept free of pillows, loose blankets, and other soft objects.

Why the other options are unsafe

| Option | Sleep practice | Main risk |
| --- | --- | --- |
| 1 | Soft pillow under head on family mat | Airway obstruction, rebreathing, positional asphyxia |
| 2 | Side-lying with rolled blanket behind back | Infant can roll prone; blanket is a soft object near the face |
| 3 | Sleeping between parents on family mat | Overlay, entrapment, overheating, suffocation |

Watch out! Side-lying is not a safe compromise. Even with a blanket roll behind the back, the infant can shift to prone, and the rolled blanket itself becomes a soft object that can cover the face. Supine is the only recommended position for every sleep period [3].

Pathophysiology link

Infants have immature arousal responses and relatively poor head control. On a soft surface, the face can sink into the material, causing rebreathing of exhaled carbon dioxide and progressive hypoxemia. In an adult bed or shared mat, an adult or heavy blanket can cover the infant’s airway, and the adult body can trap heat, raising the risk of overheating. A firm, flat, dedicated surface reduces these mechanical and thermal hazards while keeping the infant close enough for feeding, comforting, and monitoring.

Clinical application

The nurse should teach the family to place the infant on a separate mat that is firm and flat, with no pillow, no loose blanket, and no rolled cloth under or beside the infant. The mat is placed immediately next to the parents’ sleeping area, which supports room-sharing without bed-sharing. The infant is put down on her back for every sleep, including naps. If the family uses a blanket for warmth, it should be tucked firmly and kept away from the face, or the infant can wear a sleep sack appropriate for the room temperature.

Why this matters for licensure exams

Safe sleep questions test recognition of the single correct combination: back to sleep, firm flat surface, no soft objects, room-sharing without bed-sharing. Distractors typically insert one unsafe element such as a pillow, side-lying, or co-sleeping between adults. The correct answer is the option that keeps all four elements intact.

Evidence context

SUID accounts for approximately 3,400 infant deaths annually in the United States, and the recommended preventive strategy centers on supine positioning on a firm, nonshared surface without soft bedding [3]. Qualitative studies show that even when families receive a free crib, actual use and adherence vary, and caregiver beliefs strongly influence sleep practices . Surveillance data also indicate that adherence to safe sleep recommendations remains inconsistent across sociodemographic groups . These findings reinforce the need for clear, practical teaching that adapts the safe sleep principles to the family’s available resources, as in the floor-mat scenario.References (research sources)

## 임상 시나리오

Safe Sleep Without a CribFloor-mat sleeping guidance for a 1-week-old
When no crib is available, the infant should have a separate, firm, flat sleep surface placed close to the parents. A dedicated firm mat can serve this purpose if it is kept free of soft bedding, pillows, and loose blankets.

The newborn must always be placed supine for every sleep period. This single practice has the strongest evidence for reducing SIDS and SUID risk.

CautionDo not place the infant between parents, on a soft pillow, or in a side-lying position with a rolled blanket. These practices increase the risk of overlay, entrapment, rebreathing, and positional asphyxia.

## 핵심 개념

- **Supine position** — Placing an infant on their back to sleep, which reduces the risk of sudden infant death syndrome (SIDS).
- **Sudden unexpected infant death (SUID)** — The sudden and unexpected death of an infant less than 1 year old, often occurring during sleep; includes SIDS, accidental suffocation, and unknown causes.
- **Safe sleep environment** — A sleep setting that includes a firm, flat, nonshared surface without soft bedding, pillows, or loose blankets, with the infant placed on their back.
- **Rebreathing** — Inhalation of exhaled carbon dioxide when an infant's face is near soft bedding, leading to hypoxia and increased SIDS risk.
- **Overlay** — A suffocation mechanism in which an adult or older child rolls onto or covers an infant during bed-sharing, blocking the infant's airway.
