ممرض يقيس ضغط مريض بالجهاز اليدوي. أي خطأ في الطريقة يعطي قراءة أعلى من الحقيقية؟

A nurse takes a manual blood pressure. Which technique error gives a falsely high reading?

1. Supporting the arm at heart level
2. Letting the client rest 5 minutes first
3. Using a small cuff on a large arm
4. Deflating the cuff at 2–3 mmHg per second

Answer: C) Using a small cuff on a large arm. A cuff too small for the arm reads falsely high, and one too large reads low. Arm at heart level, rest beforehand and slow deflation are correct technique.
