Question 1

In bradycardia (brady- slow + cardi heart + -ia condition), what does the prefix brady- indicate?

  1. Fast
  2. Around
  3. Slow (correct answer)
  4. Above normal
Explanation: This question tests understanding of medical terminology components (root words, prefixes, suffixes). Medical terms are often composed of root words, prefixes, and suffixes that define their meaning. For example, 'cardiomegaly' combines 'cardio' (heart) and 'megaly' (enlargement). In this passage, terms are broken down into components, helping coders understand their meanings in a clinical setting. The Correct choice C is accurate because it correctly interprets the prefix 'brady-' as used in standard medical terminology to indicate slow. Choice 'A' fails because it misinterprets the prefix, a common error when the prefix is confused with a similar-sounding component like 'tachy-' for fast. Teach students to identify each component's standard meaning and its application in medical contexts. Practice decomposing complex terms into familiar parts for accurate coding.
