## 문제

Situation: A nurse handles the under-five clinic of a Barangay Health Station (BHS).

The nurse will teach a group of mothers how to prepare oral rehydration solution at home. Which teaching method is MOST effective?

## 보기

1. Demonstration by the nurse while the mothers watch and ask questions
2. A video of ORS preparation followed by a question-and-answer session
3. An illustrated step-by-step guide that each mother follows at home
4. Demonstration followed by return demonstration **✔ 정답**

**정답: 4**

## 해설

Preparing ORS is a psychomotor skill. The best method is to demonstrate the steps and then have each mother perform them in a return demonstration so that the nurse can observe and correct errors.

## 심화 해설

Clinical context

Teaching a mother to prepare oral rehydration solution (ORS) at a Barangay Health Station is not a knowledge-only task. It is a psychomotor skill that requires accurate measurement, mixing, and technique. Errors in water volume or mixing can make the solution ineffective or even dangerous, so the teaching method must allow the nurse to directly observe performance and correct mistakes.

Why demonstration alone is insufficient

A nurse-led demonstration while mothers watch and ask questions supports comprehension, but it does not confirm that a mother can perform the steps correctly on her own. Watching a video or reading an illustrated guide has the same limitation. Structured teaching can improve knowledge and reported use of ORS, but knowledge gain alone does not guarantee accurate preparation at home [1]. In community settings, gaps in practice regarding ORS preparation have been identified even when caregivers believe they know the steps [3].

Why return demonstration is the most effective method

Demonstration followed by return demonstration closes the loop between seeing, doing, and being corrected. The nurse first models the correct sequence, then each mother performs the same steps while the nurse observes. This allows immediate identification of errors such as using the wrong cup size, adding too much or too little water, or failing to mix thoroughly. The importance of accurate water volume is a recurring problem in ORS preparation, and a standard measuring container is often unavailable or misunderstood [3]. Return demonstration directly addresses this by letting the nurse verify the actual volume and technique used.

Evidence on teaching format

Group teaching can be cost-effective and can improve ORS knowledge and usage, but the outcome depends on whether mothers are able to practice the skill, not just hear about it [2]. A systematic review of educational interventions for childhood diarrhea prevention found that caregiver education can promote preventive behaviors, but the most reliable effects occur when the intervention includes a practical, skill-building component rather than passive information delivery [4]. Psychomotor accuracy is best ensured through observed practice with corrective feedback, which is exactly what return demonstration provides.

Watch out! Do not confuse comprehension with competence. A mother may nod and say she understands after watching a demonstration or video, but still prepare ORS incorrectly at home. The only way to verify competence before discharge from the health station is to watch her do it.

Key point! For any psychomotor skill taught in community or clinical settings—ORS preparation, inhaler use, insulin injection, wound care—the gold standard teaching method is demonstration plus return demonstration. This is a high-yield concept for licensure examinations.

| Teaching method | Knowledge gain | Skill verification | Error correction | Suitability for ORS preparation |
| --- | --- | --- | --- | --- |
| Demonstration only | Yes | No | Limited | Incomplete |
| Video + Q&A | Yes | No | Indirect | Incomplete |
| Illustrated guide at home | Partial | No | None | Unreliable |
| Demonstration + return demonstration | Yes | Yes | Immediate and direct | Most effective |

Clinical reasoning for the nurse

At the under-five clinic, the nurse should prepare a clean demonstration area, show the correct ratio of water to ORS packet using the locally available standard container, and then have each mother repeat the procedure. The nurse observes for accurate water volume, complete dissolution of the powder, and use of a clean container. Any deviation is corrected on the spot, and the mother repeats the step until it is correct. This approach is consistent with the finding that measurement accuracy is a major challenge in ORS preparation and that caregiver practice must be directly observed to ensure safety [3].References (research sources)

## 임상 시나리오

Teaching ORS Preparation at HomeClosing the gap between seeing and doing
ORS preparation is a psychomotor skill, not just knowledge. The most effective method is demonstration followed by return demonstration so the nurse can observe each mother perform the steps and correct errors immediately.

Accurate water volume is critical. Using too much or too little water can make the solution ineffective or dangerous, so direct observation of measurement and mixing is essential.

CautionDo not rely on demonstration, video, or printed guides alone. Knowledge gain does not guarantee correct home preparation, and caregivers may believe they know the steps while still making preparation errors.

## 핵심 개념

- **Return demonstration** — A teaching method in which the learner performs a skill after the teacher models it, allowing direct observation and correction of errors.
- **Psychomotor skill** — A skill requiring physical movement and coordination, such as measuring, mixing, and preparing ORS.
- **Oral rehydration solution** — A fluid mixture of clean water, salt, and sugar used to prevent or treat dehydration, especially in children with diarrhea.
