  2. Lecture 5 WORDS WITH TWO ROOTS & Abbreviations and symbols

  3. Intended Learning Outcomes • By the end of this lecture, students will learn: • Words with two roots , Spelling, abbreviations and symbols

  4. Lecture content • Words with two roots • Spelling importance • Abbreviations and symbols

  5. Words with two roots • In words with 2 roots, Each word root uses a combining vowel • Remember combining vowels connect roots to suffixes and roots to other roots. • The combining vowel plus the root is called a combining form. • How many combining forms are there in the word: ELECTROCARDIOGRAM ?

  6. ELECTROCARDIOGRAM ELECTR/O/CARDI/O/GRAM Root (electricity) Combining vowels root (heart) Combining vowels Suffix Record Combing form Combining form

  7. ELECTROCARDIOGRAM • Thus the entire term means: “record of the heart electricity”

  8. GASTROENTEROLOGY GASTR/ O / ENTER / O / LOGY Root (“stomach”) Combining vowel Root (“intestines”) Combining vowel Suffix (“study of”) Combing form Combing form

  9. GASTROENTEROLOGY • The two combining forms are GASTR/O and ENTER/O. • The entire word (reading from the suffix, back to the beginning of the term, and across) means: “study of the stomach and the intestines”

  10. GASTROSCOPE GASTR / O / SCOPE Root “stomach” Combining vowel Combining form Suffix “Instrument to visually examine “Instrument to visually examine the stomach”

  11. Gastroscope

  12. GASTRIC GASTR/ IC Root (“stomach”) Suffix (“pertaining to”) “Pertaining to the stomach”

  13. GASTR / IC • Notice that the combining vowel is not used when the suffix (-IC) begins with a vowel. • Words ending in –IC mean “pertaining to.” Gastric banding

  14. Gastric ulcer

  15. CARDIAC CARDI/AC CARDI ROOT(HEART) AC SUFFIX (PERTAINING TO)

  16. CARDI / AC • Again, the combining vowel is dropped when the suffix (-AC) begins with a vowel. • Words ending in –AC mean “pertaining to.”

  17. ENTERITIS ENTER/ ITIS Root (“intestines”) Suffix (“inflammation”) “Inflammation of the intestines”

  18. ENTER / ITIS • Again, the combining vowel is dropped when the suffix (-ITIS) begins with a vowel.

  19. GASTROENTERITIS GASTR / O / ENTER / ITIS Root (“stomach”) Combining vowel Root (“intestines”) Suffix (“inflammation”) “Inflammation of the stomach and intestines Combining form

  20. GASTR / O / ENTER / ITIS • Notice that the combining vowel (O) remains between the two roots even though the second root (ENTER) begins with a vowel.

  21. Prefix importance • Many medical terms also have a word part attached to the beginning of the term. This is called a Prefix. • It can change the meaning of a term in important ways • For example, watch what happens to the meaning of the following medical terms when the prefix changes…

  22. PREFIX _____GASTRIC SUB / gastr / ic = “pertaining to below the stomach” Prefix (“below”)

  23. PREFIX _____GASTRIC Trans/ gastr/ ic = “pertaining to across the stomach” Prefix (“Across”)

  24. PREFIX _____GASTRIC Retro/ gastr / ic = “pertaining to behind the stomach” Prefix (“behind”)

  25. Spelling • Correct spelling is critical in medical terminology and healthcare. • Misspelled words can lead to diagnostic, medication and treatment errors. • Some words look or sound similar and can be confusing.

  26. Spelling • Pay attention to the context to help you figure out the correct meaning of a term. • Example: “The client has a fractured ilium” ilium = part of the hip bone ileum = part of the intestine

  27. Abbreviations & symbols • Medical abbreviations and symbols are a “short hand”for medical professionals • Most have been standardized and are universally accepted.

  28. Abbreviations & symbols • Individual facilities and specialties may use their own specific abbreviations and symbols or use a symbol differently depending on the context. Example: Means “change” • But In maternity care it is also used to mean “trimester”

  29. Abbreviations & symbols • Don’t assume you know what an abbreviation or symbol means. • Learn the abbreviations and symbols used on your clinical site during orientation to the practice, through chart review, and by asking.

  30. Abbreviations & symbols • Don’t use your own personal abbreviations in health care documents. • Use only standard medically accepted abbreviations and those used by the facility on your clinical site • Use capital and small letters appropriately • Non-standard abbreviations can result in medical errors and fines for the agency when discovered during chart audits.
