QUESTION 3Which of the following terms demonstrates the correct use of a combining vowel in a medical term/word? artergram diverticulosis valvulplasty diverticuitis

The correct use of a combining vowel in a medical term/word is demonstrated in the term "valvulplasty".

Here's the step-by-step breakdown:

1. In medical terminology, a combining vowel is used for ease of pronunciation and is most commonly an 'o', but can also be an 'i'. It is used when the suffix begins with a consonant, not a vowel.

2. The term "artergram" does not use a combining vowel.

3. The term "diverticulosis" does use a combining vowel 'o' between 'diverticul' and 'osis', but it's not the correct answer because the suffix begins with a vowel, not a consonant.

4. The term "valvulplasty" uses a combining vowel 'o' between 'valvul' and 'plasty'. This is the correct answer because the suffix 'plasty' begins with a consonant.

5. The term "diverticuitis" is not a valid medical term, possibly a misspelling of "diverticulitis". Even if it was "diverticulitis", it would not be the correct answer because the suffix begins with a vowel, not a consonant.
