NCMA Medical Terminology and Abbreviations 2 — Questions and Answers

Question 1: What does 'HEENT' stand for in a physical examination documentation?

Heart, Endocrine, Extremities, Neurological, Throat
Head, Eyes, Ears, Nose, and Throat (Correct answer)
History, Examination, Evaluation, Notation, Treatment
Head, Ears, Elbows, Neck, Thorax

Correct answer: Head, Eyes, Ears, Nose, and Throat

HEENT is a standard physical examination abbreviation for Head, Eyes, Ears, Nose, and Throat. It represents the systems reviewed in the head and neck portion of a physical examination.

Common clinical abbreviations in examination documentation: HEENT = Head, Eyes, Ears, Nose, Throat; RRR = Regular Rate and Rhythm (heart); CTA = Clear to Auscultation (lungs); WNL = Within Normal Limits; NAD = No Acute Distress; A&O x3 = Alert and Oriented to person, place, and time (x4 includes time); PERRLA = Pupils Equal, Round, Reactive to Light, and Accommodation; TTP = Tender to Palpation; ROM = Range of Motion; DTR = Deep Tendon Reflexes; c/o = complaint of; s/p = status post (after a procedure/event); h/o = history of; Hx = history; Dx = diagnosis; Tx = treatment; Rx = prescription; SOB = shortness of breath; DOE = dyspnea on exertion; CP = chest pain.

Question 2: The medical term 'hematuria' means:

Blood in the sputum (coughed-up mucus)
Blood in the urine (Correct answer)
Blood in the stool
Blood in the cerebrospinal fluid

Correct answer: Blood in the urine

Hematuria is derived from 'hemat/o' (blood) + 'uria' (urine condition). It describes the presence of red blood cells in the urine, which can be visible (gross hematuria) or detectable only on urinalysis (microscopic hematuria).

Terms using '-uria' (urine condition suffix): Hematuria = blood in urine; Pyuria = pus/white blood cells in urine (infection); Proteinuria = protein in urine (kidney disease); Glucosuria/glycosuria = glucose in urine (diabetes, exceeded renal threshold); Dysuria = painful urination; Polyuria = excessive urine output; Oliguria = decreased urine output (<400 mL/day); Anuria = no urine output (<100 mL/day); Nocturia = excessive urination at night; Hematospermia = blood in semen. Urine blood: hemat/o; sputum blood: hemoptysis; vomit blood: hematemesis; stool blood: hematochezia (bright red, lower GI) or melena (dark tarry, upper GI); CSF blood: suggests subarachnoid hemorrhage.

Question 3: Which of the following abbreviations should be avoided in medical documentation because of potential for misinterpretation?

BP (blood pressure)
U (units) (Correct answer)
HR (heart rate)
ROM (range of motion)

Correct answer: U (units)

The abbreviation 'U' for 'units' is on the ISMP (Institute for Safe Medication Practices) dangerous abbreviations list because 'U' can be misread as '0' (zero) or '4,' leading to 10-fold medication dosing errors. 'Units' should always be written out in full.

ISMP and TJC (The Joint Commission) 'Do Not Use' abbreviations: U or u (units) — mistaken for 0, 4, or 'cc'; IU (international units) — mistaken for IV (intravenous) or 10; Q.D., Q.O.D. — easily confused with each other or 'qid'; Trailing zero (1.0 mg) — decimal point missed → tenfold overdose; Naked decimal point (.5 mg) — decimal point missed → tenfold overdose; MS, MSO4, MgSO4 — confusion between morphine sulfate and magnesium sulfate. Safe alternatives: write 'units,' 'international units,' 'daily,' 'every other day,' '1 mg' (no trailing zero), '0.5 mg' (leading zero). Medical assistants must use only approved abbreviations and write out high-risk terms. Error reporting systems like MedWatch capture medication error patterns.

Question 4: The suffix '-plasty' refers to what type of medical procedure?

Surgical cutting into a structure
Surgical repair or reconstruction of a body part (Correct answer)
Visual examination of a body cavity
Surgical creation of an artificial opening

Correct answer: Surgical repair or reconstruction of a body part

The suffix '-plasty' means surgical repair or reconstruction. Examples: rhinoplasty (nose reconstruction), arthroplasty (joint repair/replacement), abdominoplasty (tummy tuck/abdominal repair), angioplasty (repair of a blood vessel).

Surgical procedure suffixes comparison: -plasty = surgical repair/reconstruction (rhinoplasty, angioplasty, arthroplasty, cranioplasty); -ectomy = surgical removal (appendectomy, colectomy); -otomy = surgical incision into (laparotomy, thyrotomy); -ostomy = surgically created opening/stoma (colostomy, ileostomy, tracheostomy); -pexy = surgical fixation to hold in place (nephropexy, retinopexy); -rraphy = surgical suturing/repair of a defect (herniorrhaphy, perineorrhaphy); -desis = surgical fusion (arthrodesis, tenodesis); -lysis = surgical freeing of adhesions (adhesiolysis); -centesis = surgical puncture to withdraw fluid (thoracentesis, paracentesis, amniocentesis). These suffixes consistently indicate procedure type across all specialties.

Question 5: What does the medical abbreviation 'NPO' mean, and when is it used?

Normal Physiological Output — used for documenting normal urine output
Nothing by Mouth (nulla per os) — used when the patient must have no oral intake, such as before surgery or a procedure requiring sedation (Correct answer)
Neurological Protective Order — used in emergency situations
No Physician Order — used when a nurse initiates care without physician directive

Correct answer: Nothing by Mouth (nulla per os) — used when the patient must have no oral intake, such as before surgery or a procedure requiring sedation

NPO stands for 'nulla per os' (Latin for 'nothing by mouth'). It is used when patients must fast, typically for 4–8+ hours before surgery or procedures requiring anesthesia, to reduce the risk of aspiration.

NPO guidelines and rationale: Purpose — prevents aspiration of gastric contents during anesthesia/sedation (Mendelson's syndrome — aspiration pneumonitis); ASA NPO guidelines for healthy adults: solid food/non-clear liquids: 8+ hours; light meal (toast, clear fluids): 6 hours; breast milk: 4 hours; clear liquids (water, apple juice, tea, black coffee): 2 hours; Patient education: explain which medications can be taken with small sips of water per physician order; document NPO start time and patient understanding; Clinical use: pre-operative fasting; procedures requiring sedation/anesthesia; bowel obstruction; NPO status for swallowing disorders while awaiting swallowing evaluation; after GI surgery. Medical assistants must verify NPO compliance before procedures and document compliance/non-compliance.

Question 6: What does the term 'benign' mean in the context of a tumor or growth?

Cancerous and able to spread to other tissues
Non-cancerous; does not invade surrounding tissue or metastasize (Correct answer)
A growth requiring immediate surgical removal
A growth caused by viral infection

Correct answer: Non-cancerous; does not invade surrounding tissue or metastasize

Benign describes a growth or tumor that is non-cancerous — it does not invade surrounding tissues or spread (metastasize) to other parts of the body. While benign tumors may grow large and cause problems by compression, they are not malignant.

Tumor classification terminology: Benign — non-cancerous; encapsulated (surrounded by fibrous tissue); does not invade adjacent tissue; does not metastasize; cells resemble normal tissue (well-differentiated); named with '-oma' suffix without qualifier (lipoma = benign fatty tumor, fibroma = benign fibrous tumor, adenoma = benign glandular tumor); Malignant — cancerous; invasive; can metastasize via lymphatic or blood vessels; cells are poorly differentiated; named with 'carcinoma' (epithelial origin) or 'sarcoma' (mesenchymal origin) suffix; In situ — malignant cells present but confined to original site, not yet invasive (carcinoma in situ); Metastasis — spread of cancer from primary site to distant organs; Biopsy types: incisional (partial sample), excisional (entire lesion removed), fine needle aspiration (FNA), punch biopsy.
