EMT MYBRADY FINAL EXAM (CHAPTERS 1-25) SUMMARY
QUESTIONS AND CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) | ASSURED SUCCESS
1. What is the primary cause of gastric distention during ventilation?
A. Excessive tidal volume
B. Airway pressures generated during ventilation that are too high ✅
C. Insufficient oxygen flow rate
D. Prolonged inspiratory time
Rationale: Gastric distention occurs when high airway pressures force air into the esophagus and
stomach instead of the lungs, often due to excessive ventilation pressure.
2. "Empty-nest syndrome" is most commonly associated with which age group?
A. Adolescence
B. Early adulthood
C. Middle adulthood ✅
D. Late adulthood
Rationale: Empty-nest syndrome typically affects parents in middle adulthood when their children leave
home.
3. The study of the body's structures is referred to as:
A. Physiology
B. Pathology
C. Anatomy ✅
D. Histology
Rationale: Anatomy focuses on the structure of the body, while physiology deals with function.
4. Which group is credited with developing the earliest documented emergency medical service?
A. Romans
B. French ✅
C. Greeks
D. Egyptians
,ESTUDYR
Rationale: The French created the first organized EMS system during the Napoleonic Wars.
5. A 12-year-old patient involved in a bicycle accident is in which stage of life?
A. Toddler
B. Preschool
C. School age ✅
D. Adolescence
Rationale: School age ranges from 6–12 years.
6. Disease-causing microorganisms like bacteria and viruses are called:
A. Toxins
B. Pathogens ✅
C. Antibodies
D. Antigens
Rationale: Pathogens are infectious agents that cause disease.
7. Why should EMTs use specific medical terminology?
A. To impress patients
B. To ensure exact and consistent communication ✅
C. To follow legal requirements
D. To shorten documentation time
Rationale: Precise terminology reduces errors in patient care and documentation.
8. The trachea branches into two mainstem bronchi at the:
A. Alveoli
B. Epiglottis
C. Carina ✅
D. Pharynx
Rationale: The carina is the bifurcation point of the trachea.
,ESTUDYR
9. For long-term ventilation with consistent rate and volume, use:
A. Bag-valve mask
B. Automatic transport ventilator ✅
C. Nasal cannula
D. CPAP
Rationale: Automatic transport ventilators provide controlled, consistent ventilation.
10. The fluid component of blood is called:
A. Hemoglobin
B. Plasma ✅
C. Serum
D. Lymph
Rationale: Plasma is the liquid portion of blood, carrying cells and nutrients.
11. Decreasing tidal volume primarily affects alveolar gas exchange by:
A. Increasing oxygen diffusion
B. Decreasing available air for gas exchange ✅
C. Enhancing CO2 removal
D. Improving lung compliance
Rationale: Reduced tidal volume limits air reaching the alveoli, impairing gas exchange.
12. Instead of "palpate your mandible," say:
A. "Feel your cheekbone"
B. "Touch your jawbone" ✅
C. "Press your forehead"
D. "Examine your skull"
Rationale: Simplifying terms improves patient understanding.
13. A child with wheezing, retractions, and nasal flaring has:
A. A clear airway
B. An inadequate airway ✅
, ESTUDYR
C. Normal breathing
D. Mild congestion
Rationale: These signs indicate respiratory distress and airway obstruction.
14. A high-pitched sound from upper airway obstruction is called:
A. Rhonchi
B. Stridor ✅
C. Wheezing
D. Rales
Rationale: Stridor is caused by partial upper airway blockage.
15. The cartilage forming the lower larynx and supporting the trachea is the:
A. Thyroid
B. Cricoid ✅
C. Arytenoid
D. Epiglottis
Rationale: The cricoid cartilage is a complete ring below the thyroid cartilage.
16. Maintaining EMT certification and skills is:
A. Optional
B. Part of professional responsibility ✅
C. Required only for supervisors
D. Needed only for hospital transfers
Rationale: Continuous education ensures competency in patient care.
17. Which scenario would MOST stress a new EMT?
A. A diabetic emergency
B. A deceased abused child ✅
C. An elderly fall
D. A minor laceration
Rationale: Pediatric trauma and fatalities are emotionally challenging.
