FBLA Review: Medical Terminology Basics

FBLA – Medical Terminology Basics

FBLA Study Guide – Medical Terminology Basics

What This Is

Medical terminology is the standardized language health?care professionals use to describe anatomy, diseases, procedures, and equipment. For FBLA/DECA you must decode these terms quickly because they appear in Business of Health Care, Medical Office Management, and Finance & Accounting events (e.g., a school?run health?clinic budget or a case study on a pharmaceutical startup). Knowing the roots, prefixes, and suffixes lets you read a doctor’s order, write a clear invoice, and communicate accurately with vendors and insurers.

Key Terms & Formulas

• Prefix – A word part placed before the root that modifies meaning (e.g., hyper? = “above normal”).
• Root (Combining Form) – The core word that indicates the body part or system (e.g., cardi/o = “heart”).
• Suffix – A word part added after the root that describes a condition, procedure, or specialty (e.g., ?ectomy = “surgical removal”).
• Combining Vowel (?o) – The vowel “o” that links a root to another root or suffix for easier pronunciation (e.g., oste/o? + ?logy-osteology).
• Medical Abbreviation – Standard shortened forms (e.g., BP = blood pressure, Rx = prescription).
• ICD?10 Code – International Classification of Diseases coding system; format A00–Z99 (e.g., J45.909 = “Unspecified asthma, uncomplicated”).
• CPT Code – Current Procedural Terminology code used for billing; 5?digit numeric (e.g., 99213 = “Office/outpatient visit, established patient, level 3”).
• Dosage Formula – Dose = (Desired Dose ÷ Concentration) × Volume (used when converting prescriptions).
• Body System Prefixes – Neuro? (nervous), Gastro? (digestive), Hemo? (blood), Pulmo? (lungs).
• Disease?State Suffixes – ?itis (inflammation), ?emia (blood condition), ?oma (tumor), ?pathy (disease).
• Procedure Suffixes – ?scopy (visual examination), ?plasty (repair), ?graphy (recording).
• Pharmacy “Rule of Six” – (Strength × Volume) ÷ Quantity = Total Dose (helps verify bulk orders for school health?store).

Step?by?Step / Process Flow

1. Identify the components – Break the term into prefix, root, and suffix (or abbreviation).
2. Translate each part – Use the FBLA?approved glossary to assign meaning (e.g., hypo? = low, glyc/o = sugar, ?emia = blood condition).
3. Re?assemble the definition – Combine the meanings in logical order (prefix-root-suffix).
4. Apply to the business context – Determine how the term impacts the case (e.g., hypoglycemia means a patient may need glucose tablets, affecting inventory budgeting).
5. Cross?check with coding – Locate the corresponding ICD?10 or CPT code to verify proper billing and cost?analysis.

Common Mistakes

• Mistake: Assuming the prefix always comes before the root in meaning (e.g., reading hyperglycemia as “low blood sugar”).
  Correction: Remember prefixes modify the root; hyper? = “above normal,” so the condition is high blood sugar.

• Mistake: Ignoring the combining vowel and treating cardi as a standalone root.
  Correction: The vowel ?o? is part of the root’s spelling; it does not change the meaning but is required for proper spelling (e.g., cardi/o?logy).

• Mistake: Mixing up ?itis (inflammation) with ?oma (tumor) because both end in “?a.”
  Correction: Memorize suffix families; ?itis = inflammation, ?oma = neoplasm.

• Mistake: Using the ICD?10 code for a symptom instead of the disease (e.g., coding R07.9 “Chest pain, unspecified” when the diagnosis is I20.9 “Angina pectoris, unspecified”).
  Correction: Always code the definitive diagnosis, not the presenting symptom.

• Mistake: Applying the dosage formula without unit conversion (e.g., mixing mg with µg).
  Correction: Convert all units to the same scale before calculating; 1?mg = 1,000?µg.

Exam Insights

1. Root?First Strategy – FBLA questions often give the definition first; start by spotting the root (e.g., “inflammation of the liver”-hepat/o? + ?itis = hepatitis).
2. Code Matching – Expect a “match the term to the correct ICD?10 code” item; the distractor will usually be a code for a related but different organ system.
3. Abbreviation Trap – Rx is a prescription, not “radiation”; watch for similar?looking abbreviations (e.g., DX = diagnosis, TX = treatment).
4. Role?Play Tip: When acting as a medical office manager, clearly state the full term before using the abbreviation; exam graders reward precise communication.

Quick Check Questions

1. Which term describes surgical removal of the gallbladder?
2. Answer: Cholecystectomy

3. Explanation: Cholecyst = gallbladder (root) + ?ectomy = surgical removal.

4. A patient’s lab report shows “hyper?natremia.” What does this indicate?

5. Answer: Elevated sodium levels in the blood.

6. Explanation: Hyper? = above normal; ?natremia = sodium condition.

7. If a prescription reads “5?mg/mL, 30?mL total,” what is the total dose in milligrams?

8. Answer: 150?mg
9. Explanation: Dose = concentration × volume-5?mg/mL × 30?mL = 150?mg.

Last?Minute Cram Sheet (10 One?liners)

1. Prefix + Root + Suffix = Full medical term – always decode in that order.
2. ?itis = inflammation; ?oma = tumor (common suffix mix?up).
3. ICD?10 codes are alphanumeric (A–Z, 0–9); CPT codes are numeric only.
4. Combining vowel “?o?” belongs to the root; never drop it when spelling.
5. Hyper? = high/above normal; hypo? = low/below normal.
6. Dosage Formula: Dose = (Desired ÷ Concentration) × Volume.
7. BP = blood pressure; HR = heart rate; Rx = prescription.
8. CPT 99213 = office visit for an established patient, level?3.
9. When coding, use the definitive diagnosis, not the presenting symptom.
10. Pharmacy “Rule of Six”: (Strength × Volume) ÷ Quantity = Total Dose – handy for bulk orders.

Good luck—master these roots and you’ll decode any health?care term the FBLA exam throws at you!
