Station Title & Timing
- Title: Cardiovascular Assessment and Patient Education (Digital Sphygmomanometry)
- Duration: 10 Minutes (2 minutes reading time, 8 minutes performance)
Learning Objectives
- Technical Skill: Demonstrate the correct application and operation of a digital sphygmomanometer.
- Clinical Reasoning: Interpret hypertensive findings and initiate a diagnostic workup.
- Communication: Explain the procedure and findings using patient-centered, lay language (Murtagh’s approach).
Patient Profile
- Name: Mr. David Miller
- Age/Gender: 52-year-old Male
- Ethnicity: Caucasian
- Occupation: Long-haul truck driver
- Social History: Smokes 10–15 cigarettes/day; high caffeine intake; sedentary lifestyle.
Presenting Complaint
Mr. Miller has presented for a routine commercial driver’s license medical check. He has no active complaints but hasn’t seen a doctor in five years.
Contextual Information
- History of Presenting Complaint: No headaches, blurred vision, or chest pain.
- Past Medical History: Overweight (BMI 29); no known chronic conditions.
- Medications: Occasional ibuprofen for back pain.
- Allergies: Nil.
- Family History: Father had a “stroke” in his 60s.
Exam Instructions
Candidate Instructions
- Introduce yourself to Mr. Miller.
- Briefly explain the importance of blood pressure (BP) screening.
- Demonstrate the correct technique for measuring BP using the digital sphygmomanometer provided on the manikin/SP.
- The examiner will provide you with the “actual” reading once the machine finishes.
- Discuss the findings and the next steps in management with the patient.
Standardised Patient (SP) Instructions
- Persona: You are cooperative but slightly anxious about losing your truck license if your health isn’t “perfect.”
- Key Question: “Is that a high reading, Doc? What does it mean for my job?”
- Behavior: If the candidate places the cuff incorrectly (e.g., tube on the back of the arm), do not correct them. Wait for the machine to error or the examiner to intervene.
Examiner Instructions
- Observe the candidate’s cuff placement closely.
- Crucial Step: Once the candidate presses ‘Start’ and the cycle completes, the machine may show a normal reading (e.g., 120/80). Interrupt and state: “The reading is 160/100 mmHg.”
- Ensure the candidate uses the “one-finger rule” and checks the digital “OK” indicator.
Key Clinical Findings
- Vital Signs: BP 160/100 mmHg (provided by examiner).
- Physical Exam: Otherwise unremarkable; no signs of end-organ damage (no pedal edema, clear lungs).
Communication Triggers (Murtagh’s Approach)
- Open-Ended Questions: “Before we start, Mr. Miller, what is your understanding of why we monitor blood pressure?” or “How have you been feeling lately in general?”
- Summarising: “So, you’ve been feeling well, but you’re concerned about your license and have a family history of stroke. Is that correct?”
- Lay Language: Avoid “sphygmomanometer” (use “BP cuff”) and “hypertension” (use “high blood pressure”).
- Handling Emotion: Acknowledge his fear regarding his occupation: “I understand your job is important to you. Our goal today is to keep you healthy so you can keep driving safely.”
Assessment & Marking Guide
| Criteria | Competency |
| Introduction | Establishes rapport, confirms identity, gains informed consent. |
| Cuff Placement | Positions tube/sensor anteriorly; cuff 1-2 cm above cubital fossa. |
| Cuff Tightness | Verifies with “one-finger rule” and checks machine’s “OK” indicator. |
| Instruction | Advises patient to remain still and quiet during the 20-second reading. |
| Interpretation | Correctly identifies 160/100 mmHg as high/Stage 2 Hypertension. |
| Management | Suggests a series of readings (Ambulatory BP or home monitoring) before diagnosis. |
| Professionalism | Empathetic, non-judgmental regarding smoking/lifestyle. |
Sample Answers / Model Performance
Explaining the Procedure
“Mr. Miller, I’d like to check your blood pressure. I’ll wrap this cuff around your upper arm. It’s important that this tube sits right at the front of your arm, as that’s where the sensors are. It will squeeze your arm for about 20 seconds. It might feel a bit tight—just like a firm hug—but it shouldn’t be painful.”
Addressing the 160/100 Reading
“The reading today is 160 over 100, which is higher than the ideal range. However, a single high reading doesn’t always mean you have chronic high blood pressure; it can sometimes be higher just because you’re at the clinic. To be sure, I’d like to have you come back for a few more checks, or perhaps give you a diary to record some readings at home. Does that sound like a fair plan?”
