A 70-year-old man is confused, has a respiratory rate of 32 per minute, blood pressure 120/80 and a normal urea. He has pneumonia. What is his CURB-65 score?
Answer and explanation
Correct answer: B. 3 points: confusion, a respiratory rate of 30 or more, and age of 65 or over
- Step 1: CURB-65 gives one point each for Confusion, Urea above 7 mmol/L, Respiratory rate of 30 or more, low Blood pressure (systolic below 90 or diastolic 60 or less) and age 65 or over. Step 2. He scores for confusion, respiratory rate and age; the urea and blood pressure are normal. Answer: 3. Why not the others: The respiratory rate does score. A blood pressure of 120/80 does not. Confusion is scored on its own.
