مريض جاء لاختبار جهد بالمشي على السير. أي تعليمات قبل الاختبار صحيحة غالباً؟

A client is booked for a treadmill stress test. Which pre-test instruction is usually correct?

1. Take an extra morning dose of the beta-blocker
2. Eat a heavy meal right before the test for energy
3. Wear formal leather-soled shoes for stability
4. Avoid caffeine and smoking for some hours before

Answer: D) Avoid caffeine and smoking for some hours before. Clients usually avoid caffeine and smoking, have a light fast and wear comfortable walking shoes. Beta-blockers may be held on the prescriber’s instructions because they blunt the heart-rate response.
