Kaplan Integrated Test D - Remediation Practice Test 2025 - Free Practice Questions and Study Guide

Clients are advised to avoid certain activities and substances before an ECG test to ensure the accuracy of the results. This includes avoiding eating solid foods, drinking caffeinated beverages, and smoking cigarettes, all of which can potentially interfere with the heart's activity and lead to misleading readings.

Eating solid foods can affect heart rate and blood pressure as digestion requires increased blood flow to the stomach, which could skew ECG results. Caffeine is a stimulant that can elevate heart rate and induce irregular heart rhythms, complicating the interpretation of the ECG. Smoking can also affect heart function and increase heart rate, leading to inaccurate data during the test.

By advising clients to refrain from these activities for 24 hours prior to the ECG, healthcare providers aim to obtain the most accurate and reliable readings possible, which are essential for diagnosing heart conditions effectively. Therefore, the most comprehensive recommendation is to avoid all of the listed behaviors, making 'all of the above' the correct choice.
