A patient hears “heart failure” and imagines that their heart may stop at any moment. A bright “Don’t worry!” can make a technically correct explanation sound dismissive. This OET nursing heart failure role-play helps you explain the condition, respond to the meaning behind the fear and make your tone match the seriousness of your words.
The original practice case draws on Set 5 in Jobin Thomas’s The Heart of Nursing Communication and the empathy and reassurance focus of OET Speaking for Nurses — Course 29. These newly written cards and examples are teaching material, not official examination cards. Read the condition lesson before attempting the model aloud.
1. Your heart failure role-play cards
Nurse role card
Setting: A cardiology ward in England, during an education conversation before discharge arrangements are finalised.
Situation: Alex Bennett, 61, has recently been diagnosed with heart failure following admission with breathlessness and ankle swelling. Treatment has begun, but the individual medicines, test results and discharge plan are not provided. Alex is comfortable at rest during this conversation and wants to understand the diagnosis. Check current symptoms and do not assume that discharge has been authorised.
Your five tasks:
- Explore Alex’s current symptoms, understanding of the diagnosis and main concern. Respond to the concern with appropriate pace and tone.
- Explain heart failure and fluid build-up in clear language, distinguishing the diagnosis from the heart suddenly stopping.
- Discuss practical self-care, including symptom and weight monitoring, food, fluids and activity, using an individual plan.
- Explore questions about medicines and explain why checking the actual prescription and reporting difficulties matter.
- Agree a manageable next step, explain when to seek urgent or emergency help and check understanding without promising an individual outcome.
Patient role card
Setting: The same cardiology ward.
Situation: You are Alex Bennett, 61. You came into hospital because you were breathless and your ankles were swollen. You are comfortable sitting and speaking now, without new chest pain or sudden worsening. The word “failure” has frightened you: you think it means the heart could stop when you fall asleep. You have not understood how the new medicines and daily advice fit together. Your partner usually cooks; you want them involved in a later discussion.
Your five tasks:
- Describe how you feel now. When invited, say that you are frightened to sleep because you think “heart failure” means your heart is about to stop.
- Ask what has gone wrong and why your ankles became swollen. Ask whether every person with this diagnosis has the same problem.
- Ask what to do about drinks, meals, weighing yourself and returning to ordinary activities. Explain your partner’s role in preparing food.
- Say that you do not yet know what each medicine does. Ask whether feeling better means you can stop taking them and what to do if problems occur.
- Choose the first point you want clarified, explain what you would do if symptoms changed and ask how ongoing support will be arranged.
For the practice partner: Reveal the sleep-related fear after an open question. Do not supply a medicine name, fluid allowance or scan result. Allow the nurse to clarify unknown details rather than rewarding a confident guess. Remain understandably concerned even after the terminology becomes clearer.
2. Understand heart failure before offering reassurance
What does the heart normally do?
The heart moves blood around the body. Blood travels through the lungs to pick up oxygen and then reaches the organs and tissues that need it. The heart must both fill and squeeze effectively. Explaining these two actions helps avoid the misleading suggestion that every heart problem is simply a weak squeeze.
In heart failure, the heart is not meeting the body’s needs as effectively as it should. It may be weakened, or it may be too stiff to fill properly. The American Heart Association’s explanation of heart failure types describes these differences. Alex’s subtype is not supplied: explain the possibilities without assigning one.
Does “failure” mean the heart has stopped?
No. Heart failure describes a problem with heart function; cardiac arrest describes the sudden loss of effective pumping that requires emergency resuscitation. Correcting the meaning of the diagnosis is appropriate. Promising that Alex could never have an emergency is not. Those are very different statements, even if both are intended to reassure.
Try: “The name does not mean that your heart has stopped. It means it needs treatment because it is not working as well as it should.” Then acknowledge that it is a serious condition. Avoid “It’s only a tired heart” or “There’s nothing to worry about”. Such phrases may replace a frightening misunderstanding with an equally inaccurate impression that treatment is unimportant.
Why can fluid collect in the lungs or ankles?
Changes in circulation and the body’s handling of salt and water can lead to fluid accumulating. Fluid in the lungs can contribute to breathlessness; fluid in tissues can cause swelling, including around the ankles. “Congestive” refers to this build-up. It does not mean an infection or that the patient simply drank too much.
The American Heart Association’s heart failure overview explains how the heart and kidneys respond to these changes. For speaking practice, connect the mechanism to Alex’s experience in a short explanation. A detailed account of every chamber and hormone is unlikely to answer the immediate fear about sleeping.
What is known, and what still needs checking?
Heart failure has several possible causes, such as coronary heart disease, high blood pressure or valve problems. Knowing the diagnosis does not identify Alex’s cause. Tests and clinical assessment help the team understand the problem and choose treatment. An echocardiogram is a heart ultrasound; an ejection fraction describes the proportion of blood squeezed out of a pumping chamber with each beat.
You do not need to invent a percentage to sound knowledgeable. Neither the test findings nor an individual prognosis appears on these cards. The British Heart Foundation’s condition guide covers causes, assessment and different forms of heart failure. In the role-play, offer to clarify the actual findings with the team.
What can treatment aim to achieve?
Treatment can help manage symptoms and reduce the effects of the condition. Different medicines have different purposes: some help remove excess fluid, while others reduce strain or improve outcomes in suitable patients. The combination depends on the person’s type of heart failure, other conditions and response. A general explanation is not a prescription.
Begin with the actual medicine list. Establish what Alex has understood, explain the purpose of each prescribed item and check the instructions and relevant monitoring. Discuss difficulties with the team instead of inventing dose changes. The BHF’s living-with-heart-failure guidance explains why medicine review and discussion of side effects matter. Feeling better does not itself authorise stopping treatment.
Why monitor symptoms and weight?
A sudden weight increase can reflect fluid retention rather than a change in body fat. The BHF’s weight-gain guidance describes this connection. If daily weighing is advised, a consistent routine and a written record make changes easier to discuss. Check that the person has suitable scales and can use them safely.
Monitoring must lead to an action. Confirm which changes the individual team wants reported, how soon and to whom. The American Heart Association’s symptom-monitoring advice emphasises agreeing the concerning weight change with the healthcare professional. Do not make up a universal threshold or imply that breathlessness can be ignored until a particular number is reached.
Must everyone restrict drinks and salt in the same way?
No. Do not turn the word “fluid” into an automatic daily allowance. NICE NG106 advises against routinely imposing sodium or fluid restriction on everyone with heart failure. Ask about intake and check the individual clinical advice. Some people do need specific limits, but that decision is not supplied in Alex’s card.
If a restriction has been prescribed, clarify what the allowance includes and how to follow it in daily life. If it has not, do not create one. Ask what meals and drinks are usual before discussing changes. Involving Alex’s partner with permission may make the agreed plan easier to follow without assuming that the partner should make decisions for Alex.
How should activity and support be discussed?
A person may need to pace activities and have advice suited to their symptoms. Cardiac rehabilitation offers assessment and support for appropriate activity. Discuss what Alex wants to return to and what the team recommends. Do not promise immediate unrestricted activity or advise permanent bed rest simply because the diagnosis sounds alarming.
Support also includes understanding fears, treatment routines and practical barriers. Ask whether written information or another conversation with a chosen person present would help. Check arrangements before describing appointments as booked. Honest reassurance can concern the next achievable action even when the longer-term course is uncertain.
Which changes require urgent help?
New or worsening breathlessness, increasing swelling or sudden weight gain should prompt contact according to the agreed plan; seek urgent advice if the team cannot be reached. For this England scenario, urgent GP or NHS 111 help is appropriate for concerning changes such as breathlessness during ordinary activity or lying down. Do not wait for a routine review.
Severe breathing difficulty, abnormal blue, grey or very pale colour, or a collapse with abnormal responsiveness requires 999. Follow the call handler’s instructions. On the ward, alert staff immediately. The NHS heart failure page distinguishes urgent and emergency help. Teach this clearly without suggesting that an emergency is inevitable.
3. Task guidance: make the tone fit the message
Task 1: Hear the meaning before correcting the word
Check how Alex feels now, then ask what the diagnosis means to them. “What went through your mind when you heard the name?” invites a specific answer. Once the fear about sleep emerges, acknowledge it in a steady voice. A rapid question followed immediately by your explanation does not provide a real opportunity to answer.
Task 2: Explain without minimising
Separate the diagnosis from cardiac arrest, explain weakened or stiff heart function and link fluid build-up to symptoms. Give one idea at a time. Ask which part needs another explanation. Keep your voice calm when saying “serious”; an abrupt change into an alarming tone can undermine an otherwise balanced message.
Task 3: Make daily advice usable
Ask about existing routines and written advice before suggesting changes. Monitoring is useful only when Alex knows what to record and what action to take. Check fluid guidance and activity advice rather than supplying familiar numbers from memory. Ask permission to include the partner and identify one practical question to resolve first.
Task 4: Work from the real prescription
Invite Alex to describe the medicines in their own words. Explain that the team can review purpose, timing, side effects and monitoring together. Avoid listing assumed tablets. If the patient reports a new symptom, assess it before calling it a side effect. A communication lesson must not train the learner to diagnose from a guess.
Task 5: Close with a plan the patient can repeat
Summarise the main concern and the next action. Distinguish routine questions, worsening symptoms and emergencies. Ask Alex to explain the plan as a check on your clarity, not a memory test. Leave space for continuing fear: a successful explanation does not require the patient to finish with complete confidence.
4. Extended nurse-viewpoint model answer
This is a teaching model across the encounter, not one uninterrupted speech. The italic prompts mark genuine opportunities to listen. Use the patient’s answers to decide what comes next; do not speak private details from the patient card before they have been shared.
“Hello, Alex. I’m the nurse talking with you about your diagnosis and the questions you have before going home. How are you feeling at the moment? Has your breathing changed, or are you having any new discomfort?”
Listen and assess. The supplied case is comfortable at rest; if the partner introduces an acute change, respond to it before continuing the lesson.
“Before I explain anything, could you tell me what you understand by heart failure? What has been most on your mind since the diagnosis?”
Allow time for the fear about sleeping to emerge. Keep a calm pace rather than rushing to reassure.
“You have been worrying that your heart might stop as soon as you fall asleep. That sounds frightening to be carrying around. Thank you for telling me. Would it help if we started with what the name actually means?”
“Heart failure means that the heart is not working as effectively as the body needs. It does not mean that it has stopped. Some people have a heart that does not squeeze strongly enough; in others, the muscle is stiff and does not fill as well between beats.”
“It is a serious condition that needs treatment and follow-up. I do not want to dismiss that. At the same time, the word ‘failure’ does not tell us that your heart is about to stop tonight. We should discuss your own findings and treatment with the team rather than make a prediction from the name.”
“What is your understanding of that distinction? Is the fear mainly about what might happen during sleep, or is there something else about the diagnosis that we should talk through?”
Listen. Respond to the remaining question before moving to lifestyle advice.
“You asked about your swollen ankles. When the circulation is affected, fluid can collect in the tissues. It can also collect in the lungs and contribute to breathlessness. That is why the team looks at breathing, swelling and other findings together.”
“The diagnosis does not mean everyone has exactly the same type or cause. We can check what your tests show and which explanation applies to you. Is there a word from the doctor’s explanation or a test result that you would like us to clarify?”
“You also have questions about the medicines. Could we look at your actual medicine list together? Tell me what you have been told about each one so far, including anything that seems difficult or worrying.”
Pause for the answer. Do not substitute an assumed prescription for the missing list.
“Different medicines do different jobs. For example, a water tablet may be used to remove extra fluid, while other treatments help reduce the strain on the heart or manage the particular type of heart failure. We need to explain the purpose and instructions for the medicines you have actually been prescribed.”
“Feeling better is encouraging, but it does not mean you should stop the medicines yourself. If you have a possible side effect, difficulty taking them or a question about a dose, contact the team for advice. We can check that you know the right contact and the instructions for each medicine.”
“What have you been told about checking your weight and symptoms at home? Do you have scales you could use safely, and would keeping a short written record be manageable?”
“A sudden increase in weight can sometimes mean extra fluid is building up. The team should make clear which changes to report and what to do. We should write down your own plan rather than leave you trying to remember a number or decide by yourself whether a change matters.”
“You asked about drinks and meals. Has anyone given you a specific fluid allowance or other instructions? I will check that before suggesting a limit, because the advice is not identical for everyone. What would an ordinary day of food and drinks look like for you?”
Listen for the partner’s role in cooking, and ask what involvement Alex wants.
“You would like your partner involved because they usually prepare the meals. With your permission, we can check how to include them in the discussion. You should both have a clear explanation of any agreed changes and a chance to ask questions.”
“Which ordinary activity are you most hoping to get back to? We can ask the team about suitable activity and cardiac rehabilitation. The aim is a plan that fits your condition, with pacing and support where needed, rather than expecting you to do everything immediately.”
“Before we finish, let’s separate the types of help you might need. If breathing or swelling gets worse, or your weight changes suddenly, follow the contact plan promptly. If you cannot reach the team, seek urgent medical advice through your GP or NHS 111 instead of waiting for the next routine appointment.”
“If you have severe difficulty breathing, cannot get words out, develop an abnormal blue or grey colour, or collapse and are not responding normally, someone should call 999. Those symptoms need emergency help. While you are here on the ward, tell staff immediately about any new change.”
“I have covered several things. Which would be most useful to sort out first: the explanation of your diagnosis, your medicine list, or the written plan for home?”
Agree the priority from Alex’s answer. Clarify actual arrangements without inventing a discharge date, review appointment or promised service.
“To check that I have explained this clearly, could you tell me what heart failure means in your own words and what you would do if your symptoms changed? We can go back over any part that is unclear.”
“You do not have to feel completely confident after one conversation. We can identify the questions that remain and make sure they are raised with the team. What would you most like me to explain again?”
5. Speaking tips: let the delivery support the meaning
Pause after acknowledging the fear. Say “That sounds frightening” at an ordinary, steady pace, then let Alex respond. If you immediately add a cheerful “but”, the acknowledgement can sound like a phrase used only to move the patient along.
Emphasise the distinction, not the patient’s error. Compare “That is NOT what it means” with a gentler emphasis on “not working as effectively”. The second directs attention to the explanation. You are helping the person understand an unfamiliar label, not correcting a careless mistake.
Use your natural voice. Empathy does not require whispering, exaggerated sadness or a different accent. Aim for clear phrasing, audible volume and space between ideas. Ask a partner whether the delivery made it easy to interrupt with a question.
Keep the seriousness consistent. “This needs ongoing treatment” should not be followed by “You’ll be completely fine”. That later promise cancels the earlier accuracy. Reassure through a clear next step and an honest account of what can be explained or arranged.
Review one feature at a time. Record a short segment using fictional details. First listen for places where you asked a question without leaving a pause. Then listen for emphasis on words such as “just”, “only” or “obviously”. Re-record one segment and compare the effect before attempting the whole encounter.
6. Useful sentences for a serious diagnosis
- Explore the meaning: “What did those words mean to you when you first heard them?”
- Acknowledge the particular fear: “You are worried about what might happen when you fall asleep.”
- Invite explanation: “Would it help to go through what the diagnosis means?”
- Hold both truths: “It needs ongoing treatment, but the name does not mean your heart has stopped.”
- Stay within the facts: “Let’s check which findings and treatment apply to you.”
- Clarify a routine: “What instructions have you already been given about drinks and weighing yourself?”
- Invite a difficulty: “Which part of taking the medicines might be hardest to manage at home?”
- Offer genuine choice: “Would you like your partner involved in that discussion?”
- Check your explanation: “What will you do if your breathing becomes worse?”
- Make room for concern: “Which worry have we not yet addressed?”
7. Common mistakes and how to repair them
- “Don’t worry, it’s just a weak heart.” This minimises the condition and excludes stiffness. Repair: explain impaired function in plain language and acknowledge that the diagnosis needs ongoing care.
- “Your heart definitely will not stop.” Correcting terminology is not a personal risk guarantee. Repair: distinguish heart failure from cardiac arrest and refer questions about individual risk to the actual assessment.
- “Drink exactly 1.5 litres every day.” The card supplies no restriction. Repair: check whether there is an individual allowance and clarify it before advising.
- “You will take these three tablets.” This invents a regimen. Repair: review the prescribed list and explain only what can be verified.
- “Call only if the scales reach this number.” This can make a patient ignore symptoms. Repair: explain the personal monitoring plan and the separate need to respond to worsening breathing or swelling.
- “I understand” followed by another prepared paragraph. The words alone do not show listening. Repair: reflect the specific concern, pause and answer the question the patient actually asked.
- “We’ve explained that already.” This can close the conversation. Repair: ask which part remains unclear and try a shorter explanation or a different example.
8. Repeat with a changed answer
For the first attempt, keep Alex’s fear about sleeping. Afterwards, ask the partner to identify one point where your voice matched the message and one where you sounded rushed. Check whether you explained the condition before giving daily instructions. Choose one improvement and repeat that section.
Second attempt: the concern is about being dismissed
Replace the initial worry with: “I know my heart hasn’t stopped. Everyone keeps explaining that. I’m worried because I don’t know who to call when I get home.” Keep the diagnosis and current stable symptoms. Ask a useful follow-up question and respond before opening the example.
Read a possible response and why it fits
“Thank you for making that clear. You already understand the name; the missing part is knowing where to get help. What contact information have you been given so far?”
“Let’s check the actual team contact, when that service is available and what to do outside those hours. I would like you to have those details in the written plan before discharge arrangements are finalised. We should also separate routine questions from worsening symptoms and emergencies.”
Why this works: The nurse accepts the correction and changes direction. The response does not repeat an unwanted explanation, invent a telephone number or promise continuous access to a particular nurse. It identifies the information that needs checking and keeps the patient involved.
Check the second recording
- Did I notice that the patient’s concern had changed?
- Did my tone acknowledge the correction without sounding defensive?
- Did I ask what contact information was already available?
- Did I distinguish confirmed arrangements from what still needs checking?
- Did I retain clear urgent and emergency advice?

Source notes
The complete Set 5 paired cards, condition explanation, phrases and model in The Heart of Nursing Communication were consulted alongside the full saved Course 29 curriculum. This new case applies its empathy focus; it does not claim a separate heart-failure lesson exists in the curriculum. Clinical wording was checked against the linked NHS, BHF and American Heart Association material. NICE’s indexed recommendation on routine fluid and sodium restriction was checked; the full guidance page was unavailable during review. This lesson does not reproduce the source’s fixed fluid allowance, assumed medicine regimen or promises about an individual future.
