Certified Nursing Assistant (CNA) Test 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

Shingles is a skin disorder caused by the virus responsible for causing:

Measles

Rubella

Chickenpox

The correct answer is indeed chickenpox, as shingles is directly caused by the reactivation of the varicella-zoster virus, which is the same virus that causes chickenpox. When an individual contracts chickenpox, usually during childhood, the virus remains dormant in the nervous system. Years later, it can reactivate, particularly during times of stress or a weakened immune system, leading to the painful rash and blisters characteristic of shingles. Understanding this connection is crucial for candidates preparing for the CNA exam, as it highlights the importance of vaccination and awareness of how viral infections can lead to subsequent health issues later in life.
