# Situation: A 34-year-old woman is being discharged from the medical ward after treatment for an asthma exacerbation. Her discharge medicines are a salbutamol pressurized metered-dose inhaler (pMDI) as needed for symptoms and a fluticasone pMDI, two puffs twice daily, both to be used with a spacer. She is also given a peak flow meter and a written asthma action plan. She finished elementary school and says she is "not good with reading." Because of her reading level, the nurse plans to use teach-back after explaining each medicine. A nursing student asks what teach-back is meant to show. Which explanation should the nurse give?

Because of her reading level, the nurse plans to use teach-back after explaining each medicine. A nursing student asks what teach-back is meant to show. Which explanation should the nurse give?

1. It tests her memory so that her family can be taught instead if she fails
2. It has her repeat the nurse's exact words so the message stays unchanged
3. It checks how clear the teaching was, as she explains it in her own words **✔ 정답**
4. It confirms her inhaler skill, so a return demonstration is no longer needed

**정답: 3**

## 해설

Teach-back asks the client to explain, in her own words, what she was taught. It checks how well the nurse explained, not how clever the client is; if she cannot explain it, the nurse teaches it again in a different way. It is especially useful for clients with limited literacy, but a skill such as inhaler use still needs a return demonstration.

## 심화 해설

What teach-back actually measures

Teach-back is a communication technique in which the nurse asks the client to state back, in her own words, what she has just been taught about her medicines or self-care. The purpose is not to test the client’s memory or intelligence. Instead, it checks how clearly the nurse explained the information. If the client cannot restate the key points, the nurse assumes the teaching was not clear enough and explains it again using a different approach or simpler language.

This distinction matters for a client who reports limited reading ability. A written asthma action plan may be difficult for her to use, so confirming verbal understanding becomes even more important. Teach-back allows the nurse to identify which parts of the discharge instructions were not understood and to correct them before the client leaves the unit.

Key point! Teach-back evaluates the effectiveness of the teaching, not the client’s ability. The responsibility for understanding is placed on the nurse to re-teach until the client can explain the information correctly.

Why option 3 is correct

Option 3 states that teach-back “checks how clear the teaching was, as she explains it in her own words.” This matches the core definition. The client is not asked to memorize or repeat the nurse’s exact wording. Paraphrasing in her own words shows that she has processed the information and can apply it to her own situation. If she only repeats the nurse’s words verbatim, the nurse cannot be sure she truly understands the meaning.

Why the other options are incorrect

| Option | Why it is wrong |
| --- | --- |
| 1. It tests her memory so that her family can be taught instead if she fails | Teach-back is not a pass-or-fail memory test. If the client cannot explain, the nurse re-teaches using a different method. Family involvement may be helpful, but it is not the primary purpose of teach-back, and the client is not replaced as the learner. |
| 2. It has her repeat the nurse’s exact words so the message stays unchanged | Teach-back specifically asks for the client’s own words. Verbatim repetition can mask a lack of understanding because the client may simply echo the nurse without comprehending the meaning. |
| 4. It confirms her inhaler skill, so a return demonstration is no longer needed | Teach-back assesses verbal understanding of information. A psychomotor skill such as using a pMDI with a spacer still requires a separate return demonstration to confirm correct technique. Teach-back cannot replace hands-on skill validation. |

Application to this client

This client has two inhalers with different purposes: salbutamol for quick relief of symptoms and fluticasone as a daily controller, two puffs twice daily. Confusion between these medicines is a common safety risk at discharge. The nurse can use teach-back by asking, for example, “When you feel short of breath at home, which inhaler will you use? Tell me in your own words how you will decide.” If the client cannot explain the difference, the nurse re-teaches using a simpler comparison or a visual aid.

Because the client has limited reading skills, the nurse should also confirm understanding of the peak flow meter zones and the written action plan verbally. Teach-back is well suited to this situation because it does not rely on the client’s ability to read written instructions.

Evidence from the literature

Teach-back is consistently described as a strategy to confirm patient understanding and close gaps in health literacy [3]. It is a patient-centered communication tool that places the burden of clarity on the clinician rather than on the patient [3]. Studies evaluating teach-back in discharge teaching have measured whether patients can correctly state the indication and side effects of newly prescribed medications, which is exactly the type of information this client needs to understand about salbutamol and fluticasone [3].

Nursing education interventions have focused on increasing nurses’ use of teach-back to improve the quality of discharge instructions [1]. The method is taught as a way to assess patient understanding before the patient leaves the acute care setting, because transitions to home are a high-risk time for medication errors [1]. Improving patient health literacy through teach-back has also been a target of staff development programs, reinforcing that teach-back is a nursing skill that can be learned and applied consistently [2].

Watch out! Teach-back and return demonstration are not interchangeable. Teach-back verifies that the client can explain information verbally. Return demonstration verifies that the client can perform a physical skill correctly. For inhaler technique, both are needed: the client should explain when and why to use each inhaler, and also show the nurse how she uses the device with the spacer.References (research sources)

## 임상 시나리오

Teach-Back for Discharge TeachingVerifying understanding in patients with limited literacy
Teach-back asks the patient to explain the instructions in her own words. It checks clarity of the nurse's teaching, not the patient's memory or intelligence.

For a patient with limited reading ability, confirm verbal understanding of the asthma action plan and each medicine before discharge. If she cannot restate key points, re-teach using simpler language or a different approach.

CautionTeach-back does not replace a return demonstration for inhaler technique. Salbutamol and fluticasone pMDI use with a spacer still requires direct observation of skill.
