HSRT Medical Terminology 2 — Questions and Answers

Question 1: The medical term 'dyspnea' refers to:

Difficulty breathing or shortness of breath (Correct answer)
Abnormal accumulation of fluid in the lungs
Inflammation of the bronchial tubes
Absence of breathing

Correct answer: Difficulty breathing or shortness of breath

Dyspnea (dys- = difficulty, -pnea = breathing) means subjective difficulty breathing or shortness of breath.

Dyspnea derives from Greek: 'dys' (difficult, abnormal) + 'pnea' (breathing). It refers to the subjective sensation of breathlessness or difficulty breathing, reported by the patient. Dyspnea is a symptom — not a diagnosis — with many causes: cardiac (heart failure, MI), pulmonary (COPD, pneumonia, PE), neuromuscular, metabolic (acidosis), and psychogenic (anxiety). Differentiating dyspnea from apnea (absence of breathing), orthopnea (positional dyspnea), and tachypnea (rapid breathing rate) is fundamental to clinical history-taking in HSRT scenarios.

Question 2: The prefix 'brady-' in medical terminology means:

Slow (Correct answer)
Fast
Abnormal
Absent

Correct answer: Slow

Brady- comes from Greek 'bradys' meaning slow. Bradycardia = slow heart rate; bradypnea = slow breathing.

The prefix brady- derives from Greek 'bradys' (slow) and is used in clinical terms to indicate reduced rate: bradycardia (heart rate < 60 bpm), bradypnea (respiratory rate < 12 breaths/min), bradykinesia (slowness of movement, characteristic of Parkinson's disease). Its opposite is tachy- (fast): tachycardia, tachypnea. Recognizing rate-related prefixes is essential for interpreting clinical vital sign documentation, cardiac monitor interpretations, and neurological assessments in health sciences settings.

Question 3: The term 'hematuria' refers to:

Blood in the urine (Correct answer)
Blood in the stool
Blood in the sputum
Excessive urination

Correct answer: Blood in the urine

Hematuria = hemat- (blood) + -uria (urine condition). It means the presence of blood in urine.

Hematuria: hemato- (blood) + -uria (condition of urine). Blood in the urine may be macroscopic (visible to the naked eye, pink/red/brown urine) or microscopic (>3 RBCs/HPF on urinalysis). Causes include UTI, kidney stones, glomerulonephritis, trauma, and malignancy. Blood in stool is hematochezia (bright red) or melena (dark tarry = upper GI). Blood in sputum is hemoptysis. Excessive urination is polyuria. Distinguishing these related terms is fundamental to HSRT medical terminology competency.

Question 4: The suffix '-ectomy' in medical terminology means:

Surgical removal (Correct answer)
Surgical repair
Incision into
Visualization of

Correct answer: Surgical removal

The suffix -ectomy means surgical excision or removal (e.g., appendectomy = removal of the appendix, cholecystectomy = removal of the gallbladder).

-Ectomy derives from Greek 'ektomē' (excision): ek- (out) + temnein (to cut). Common examples: appendectomy (appendix removal), mastectomy (breast removal), cholecystectomy (gallbladder removal), thyroidectomy. Related suffixes to distinguish: -plasty (surgical repair/reconstruction), -otomy or -tomy (incision into: laparotomy, tracheotomy), -oscopy (visual examination: colonoscopy, laparoscopy), -ostomy (surgical opening: colostomy, tracheostomy). Mastering these procedural suffixes is essential for reading operative notes, surgical consult documentation, and coding in health sciences.

Question 5: The medical term 'leukocytosis' refers to:

An abnormally high white blood cell count (Correct answer)
An abnormally low white blood cell count
An abnormally high red blood cell count
White blood cells in the urine

Correct answer: An abnormally high white blood cell count

Leukocytosis = leuko- (white) + -cyte (cell) + -osis (abnormal increase). It means an elevated white blood cell count.

Leukocytosis: leuko- (white, from Greek leukos) + -cyte (cell) + -osis (abnormal condition, typically increase). Normal adult WBC count is 4.5–11.0 × 10³/μL. Leukocytosis (>11,000/μL) is commonly caused by bacterial infection, inflammation, stress response, corticosteroids, or leukemia. Contrast with leukopenia (leuko- + -penia = deficiency), which refers to abnormally low WBC count. Erythrocytosis refers to elevated red blood cell count. Leukocytes in urine is pyuria (pus cells) or leukocyturia — different terminology altogether.

Question 6: The anatomical term 'posterior' in clinical body planes refers to:

Toward the back of the body (Correct answer)
Toward the front of the body
Toward the midline of the body
Away from the midline of the body

Correct answer: Toward the back of the body

Posterior means toward the back (dorsal surface) of the body. Its opposite is anterior (toward the front).

Posterior (from Latin 'posterus,' coming behind) refers to the dorsal aspect — the back side — of the body or structure. In clinical documentation, posterior describes the location of findings, pain, incisions, and anatomy. Key directional term pairs: Posterior/Anterior (back/front), Superior/Inferior (above/below), Medial/Lateral (toward/away from midline), Proximal/Distal (closer to/farther from origin), Deep/Superficial (farther from/closer to surface). These terms enable precise anatomical communication without ambiguity across languages and healthcare contexts.
