NEX Vocabulary: Medical Terminology and Context Clues 2 — Questions and Answers
Question 1: The prefix 'hyper-' in medical terminology most commonly means:
- Below normal
- Above normal or excessive (Correct answer)
- Within normal range
- Absence of
Correct answer: Above normal or excessive
The prefix 'hyper-' means above normal, excessive, or beyond, as seen in terms like hypertension (high blood pressure) and hyperglycemia (high blood sugar).
Medical prefixes modify the meaning of root words. 'Hyper-' comes from Greek meaning 'over, above, beyond' and indicates excess or elevation. Common examples: hypertension (elevated blood pressure), hyperglycemia (elevated blood glucose), hyperthermia (elevated body temperature), hyperkalemia (elevated potassium), hyperthyroidism (overactive thyroid). The opposite prefix is 'hypo-' (below normal): hypotension, hypoglycemia, hypothermia. Understanding these prefixes is essential for nursing: recognizing 'hyper-' in a diagnosis immediately tells you something is elevated above normal range, guiding assessment priorities and interventions. On nursing entrance exams, prefix/suffix knowledge helps decode unfamiliar medical terms.
Question 2: Which medical term means 'inflammation of the liver'?
- Hepatomegaly
- Hepatitis (Correct answer)
- Hepatectomy
- Hepatoma
Correct answer: Hepatitis
Hepatitis combines 'hepat-' (liver) with '-itis' (inflammation). The suffix '-itis' always indicates inflammation.
'Hepat-' or 'hepato-' is the combining form for liver, derived from the Greek 'hepar.' The suffix '-itis' means inflammation. Combined: hepatitis = inflammation of the liver. Breaking down the other options: hepatomegaly = enlarged liver (hepato- + -megaly/enlargement), hepatectomy = surgical removal of the liver (hepat- + -ectomy/surgical removal), hepatoma = liver tumor (hepato- + -oma/tumor or mass). The '-itis' suffix appears in hundreds of medical terms: appendicitis (appendix inflammation), arthritis (joint inflammation), bronchitis (bronchial inflammation), dermatitis (skin inflammation). For nursing students, recognizing '-itis' immediately identifies an inflammatory condition, which helps predict symptoms (pain, swelling, redness, heat, loss of function) and potential treatments (anti-inflammatory medications).
Question 3: The term 'bradycardia' refers to:
- Rapid heart rate
- Slow heart rate (Correct answer)
- Irregular heart rate
- Absent heart beat
Correct answer: Slow heart rate
'Brady-' means slow and 'cardia' refers to the heart. Bradycardia is a heart rate below 60 beats per minute in adults.
'Brady-' comes from Greek 'bradys' meaning slow. 'Cardia' comes from Greek 'kardia' meaning heart. Bradycardia = slow heart rate, typically defined as below 60 beats per minute in adults. The opposite is tachycardia (tachy- = fast, heart rate above 100 bpm). An irregular heart rate is called arrhythmia or dysrhythmia (a-/dys- + rhythm). Other 'brady-' terms: bradypnea (slow breathing), bradykinesia (slow movement, common in Parkinson's disease). Understanding rate-related prefixes is clinically important: a nurse who reads 'patient developed bradycardia' immediately knows the heart rate dropped below normal and should assess for symptoms like dizziness, fatigue, or syncope, and check if any medications (beta-blockers, digoxin) might be responsible.
Question 4: In the sentence 'The patient's prognosis improved after treatment,' the word 'prognosis' means:
- A medical test or procedure
- A prediction of the likely course of a disease (Correct answer)
- The cause of the disease
- The symptoms of the disease
Correct answer: A prediction of the likely course of a disease
'Prognosis' comes from Greek 'prognosis' meaning foreknowledge, and in medicine refers to the predicted outcome or course of a disease or condition.
Breaking down 'prognosis': 'pro-' (before, forward) + 'gnosis' (knowledge) = foreknowledge or prediction. In medicine, prognosis is the anticipated course and outcome of a disease, including the likelihood of recovery. Related terms: diagnosis (dia- through + gnosis) = identification of a disease through examination; etiology = the cause or origin of a disease; pathology = the study of disease processes. Context clues in the sentence help: 'improved after treatment' suggests the predicted outcome got better, confirming prognosis as a prediction about the disease course. Nurses communicate prognosis to patients and families as part of patient education and care planning. Understanding this term helps nursing students comprehend clinical discussions and medical literature.
Question 5: The suffix '-ectomy' indicates:
- Viewing or examining
- Creating an opening
- Surgical removal (Correct answer)
- Surgical repair
Correct answer: Surgical removal
The suffix '-ectomy' means surgical removal or excision, as in appendectomy (removal of the appendix) or cholecystectomy (removal of the gallbladder).
Medical suffixes related to surgical procedures: '-ectomy' = surgical removal (appendectomy, cholecystectomy, hysterectomy, mastectomy); '-otomy' = cutting into/incision (tracheotomy, craniotomy); '-ostomy' = creating an opening (colostomy, tracheostomy, ileostomy); '-plasty' = surgical repair/reconstruction (rhinoplasty, arthroplasty); '-scopy' = viewing/examining (endoscopy, colonoscopy, arthroscopy). Distinguishing between these suffixes is crucial: a tracheotomy (cutting into the trachea) is different from a tracheostomy (creating a permanent opening in the trachea). For nursing entrance exams, knowing these surgical suffixes allows you to decode unfamiliar terms and understand the nature of procedures described in clinical scenarios.
Question 6: Using context clues, determine the meaning of 'aseptic' in the following sentence: 'The nurse maintained aseptic technique throughout the procedure to prevent any microorganisms from entering the surgical site.'
- Free from contamination by pathogens (Correct answer)
- Using antiseptic solutions
- Quick and efficient
- Relating to anesthesia
Correct answer: Free from contamination by pathogens
The context clue 'to prevent any microorganisms from entering the surgical site' indicates that 'aseptic' means free from contamination by disease-causing organisms.
'Aseptic' breaks down as 'a-' (without) + 'septic' (relating to infection/putrefaction) = without infection. The context clearly supports this: maintaining aseptic technique to prevent microorganisms from entering the surgical site means keeping the environment free from contamination. Distinguishing related terms: aseptic = free from pathogens (prevention-focused), antiseptic = substance that inhibits microbial growth on living tissue (treatment/chemical-focused), sterile = completely free from all microorganisms including spores. Aseptic technique in nursing includes hand hygiene, sterile gloves and gowns, sterile draping, and maintaining a sterile field. Understanding the difference between aseptic and antiseptic is important for nursing practice and frequently tested on entrance exams.
