You are an FY2 in GP

Personal Details:

Name: Emily Davis

Age: 34

Medical Record:

Past medical history: Gravida 1, Para 0. Currently 36 weeks pregnant. Uncomplicated pregnancy.

Regular medication: Standard antenatal vitamins.

Allergies: None known.

Notes:

Emily has come in for an urgent appointment. Her 3-year-old son was diagnosed with chickenpox yesterday. She is 36 weeks pregnant and is worried about her unborn baby.

Task:

1. Take a focused history, including her own chickenpox history and immunisation status.

2. Address her concerns about the risk to her and her unborn baby.

3. Provide a clear management plan and reassurance.

Opening Sentence: “Doctor, I’m in a bit of a panic. My little boy has chickenpox, and I’m 36 weeks pregnant. What does this mean for my baby?”

Open History (to give freely): “My husband took our son, Tom, to the GP yesterday, and they confirmed it was chickenpox. I’ve been trying not to worry, but I can’t help it. I’ve heard it can be dangerous in pregnancy.”

Cues to give: “I think I had it as a child, but I can’t be 100% sure.”

ICE (Ideas, Concerns, Expectations):

Ideas: “I know chickenpox is usually mild in kids, but I have a vague memory of someone telling me it’s really bad for unborn babies.”

Concerns: “Will my unborn baby get chickenpox? Could it cause any birth defects or problems for the baby after he’s born?”

Expectation: “I need to know if my baby is safe. Is there a test or something I can have?”

How to Act: You are visibly anxious and distressed. You are focused on the potential harm to your unborn child.

More History (only if asked): You are certain you had chickenpox when you were about 6 years old. You remember having the spots and your mum keeping you out of school. You have a clear memory of it. You have had all your childhood immunizations. Your pregnancy has been completely straightforward so far.

Social History: You are a teacher, currently on maternity leave. You live with your husband and your 3-year-old son.

Questions to ask:

“Are you absolutely sure the baby will be okay?”

“What if I haven’t had it? What happens then?”

Opening & Establishing Rapport:

I understand you’re calling because you’re pregnant and have been in contact with someone with chickenpox. That can be a worry, so you’ve done the right thing to call us straight away.

History of Exposure: Can you tell me about the contact? Who was it and when did you see them? How close was the contact? For example, were you in the same room for more than minutes, or did you have face-to-face contact?

Crucial Immunity Question: This is the most important question: Are you absolutely certain you have had chickenpox yourself in the past? Do you remember having it as a child? Did your parents tell you that you had it?

Pregnancy History: Congratulations on your pregnancy. How many weeks pregnant are you now? Is this your first pregnancy?

Current Symptoms (Red Flag Screening): Are you feeling well in yourself at the moment? Have you developed any symptoms, like a fever, headache, or any spots or blisters on your skin?

ICE (Ideas, Concerns, Expectations):

What are your thoughts on this? What have you heard about chickenpox in pregnancy?

What is your biggest worry right now? Are you concerned about the risk to your baby?

What were you hoping we could do for you today?

Thank you for coming in, Emily. It’s completely understandable that you’re worried; this is a very common concern. The most important question here is whether you have had chickenpox yourself in the past. You mentioned you remember having it as a child. This is excellent news.”

Addressing and answering the patient’s ICE:

Your main worry is about your baby’s safety, so let me address that directly. Because you’ve had chickenpox before, your body has developed immunity, which means you have antibodies against the virus. These antibodies not only protect you from getting ill but have also been passed across the placenta to your baby. So, your baby is protected by your immunity. This means the risk to your baby is extremely low.

Next Steps:

Because you have a clear history of having had chickenpox, no specific tests or treatments are needed for you or the baby at this stage. The immunity you have is reliable. If someone is pregnant and is not sure if they’ve had chickenpox, we would do an urgent blood test to check for antibodies, but in your case, your clear history is sufficient.

Self-help measures if relevant:

You can continue to care for your son as normal. Just maintain good hand hygiene, as you usually would. There’s no need to isolate yourself from him.

It’s important to be aware that if a pregnant woman who is not immune gets chickenpox, especially around the time of delivery, there can be risks to the baby. But again, Emily, this does not apply to you. You and your baby are protected.

Addressing ideas, concerns, and expectations: The entire case rests on addressing her concern for the baby. The management is reassured based on a key piece of historical data.

Provide confident, clear, and definitive reassurance. Explain the mechanism of passive immunity to reinforce the message.

What is scenario testing? This is a pure reassurance and explanation station. It tests the candidate’s ability to identify the single most important piece of information (previous chickenpox infection), understand its clinical significance in this context, and use it to provide effective and definitive reassurance to an anxious patient. It is a test of focused history-taking and confident, clear communication.
