Lab 1: Your First Prompt Comparison (Healthcare Edition)
Objective
Experience firsthand how prompt engineering improves AI responses by comparing a simple prompt with an engineered prompt using a real-world healthcare scenario.
Scenario
Imagine you are a healthcare administrator who wants to educate patients about high blood pressure (hypertension).
Step 1: Run the Simple Prompt
Open an LLM such as ChatGPT, Copilot, Gemini, or Claude and enter:
Explain high blood pressure.
Review the output and save a screenshot.
Step 2: Run the Engineered Prompt
Now enter:
Explain high blood pressure in 200 words to a 60-year-old patient with no medical background. Use simple language and a plumbing analogy to explain what happens inside blood vessels. Include three lifestyle changes that can help lower blood pressure. End with one question to check the patient’s understanding.
Review the output and save a screenshot.
Compare the Results
As you review both responses, consider the following:
| Question | Simple Prompt | Engineered Prompt |
|---|---|---|
| Was the explanation easy to understand? | ||
| Was the audience clearly targeted? | ||
| Did it use a helpful analogy? | ||
| Did it include practical advice? | ||
| Was the length appropriate? | ||
| Did it check for understanding? |
Learning Journal Reflection
After completing the exercise, answer the following questions:
- What differences did you notice between the two responses?
- Which response would be more useful for a patient?
- What important information was missing from the simple prompt’s output?
- How did specifying the audience improve the response?
- How did adding an analogy help explain the concept?
- What additional instructions might further improve the engineered prompt?
Key Lesson
AI performs best when you clearly define the audience, purpose, format, and desired outcome.
The AI did not become smarter between the two prompts.
You became a better communicator. That’s the first step toward becoming an AI Whisperer.
