25
What are signs of pulmonary embolism
Sudden sharp chest pain dyspnea tachycardia clear lungs
26
What is epiglottitis
Life-threatening upper airway inflammation
27
What are signs of epiglottitis
Drooling fever tripod position stridor
28
What is croup
Viral infection of the upper airway common in children
29
What are signs of croup
Barking cough stridor low-grade fever
30
What is hyperventilation syndrome
Rapid breathing due to anxiety or panic
31
What are signs of hyperventilation
Dizziness tingling chest tightness carpopedal spasms
32
What is the treatment priority for respiratory emergencies
Maintain airway support breathing administer oxygen
33
What is the most important assessment tool for respiratory patients
Pulse oximetry
34
When should you assist ventilations
When breathing is inadequate or respiratory failure is present
35
Patient is tripodting, drooling, has stridor, and a high fever, What condition should you suspect?
Epiglottitis
36
Patient with asthma is using accessory muscles, speaks in 1–2 word sentences, and has wheezing, What should you do?
Assist with prescribed inhaler if available and provide oxygen
37
A 68-year-old with a history of CHF is sitting upright, gasping, and has pink frothy sputum, What is the likely diagnosis?
Pulmonary edema from CHF
38
A young child has a barking cough, stridor, and recent cold symptoms, What is the likely condition?
Croup
39
Patient with chest pain, tachypnea, clear lung sounds, and recent surgery, What life-threatening condition should you suspect?
Pulmonary embolism
40
A tall, thin man suddenly develops sharp chest pain and dyspnea after a hard cough, What could be the cause?
Spontaneous pneumothorax
41
A patient is breathing rapidly, dizzy, and complains of numbness in hands and feet after emotional distress, What is the likely cause?
Hyperventilation syndrome
42
Unresponsive patient has shallow breathing and no chest rise, What’s your first step?
Open airway and begin assisted ventilations with BVM
43
What causes the airway narrowing in asthma?
Bronchospasm, inflammation, and excess mucus
44
What medication might an EMT assist with in a pt with asthma?
A prescribed metered-dose inhaler (MDI) or nebulizer
45
What are hallmark signs of emphysema?
Barrel chest, thin appearance, pursed-lip breathing
46
How is chronic bronchitis different from emphysema?
Chronic bronchitis involves chronic mucus production and cough; emphysema is alveolar damage
47
Why does CHF cause respiratory symptoms?
The heart can’t pump efficiently, leading to fluid backup in lungs (pulmonary edema)
48
What breath sound is commonly heard?
Crackles or rales
49
What puts a patient at high risk for pulmonary embolism?
Recent surgery, immobility, long flights, history of DVT (Deep vein thrombosis) or clotting disorder
50
What is often present with pneumonia that’s not typical in other respiratory conditions?
Fever and productive cough
51
How is Pneumonia lung sound presentation different from CHF?
Localized crackles in pneumonia vs. diffuse crackles in CHF
52
What is the age group most affected by Croup?
Children ages 6 months to 3 years
53
Why should you avoid examining the throat in a suspected Epiglottitis?
It may cause airway spasms and sudden obstruction
54
Why might hyperventilation cause tingling and muscle spasms?
Blowing off too much CO₂ causes respiratory alkalosis
55
What breath sound finding is most common in Pneumothorax?
Absent or diminished breath sounds on one side
56
What are early signs of respiratory compromise
Restlessness anxiety increased work of breathing tachypnea
57
What are late signs of respiratory failure
Cyanosis altered LOC bradypnea silent chest
58
What are signs of respiratory distress in children
Nasal flaring grunting retractions accessory muscle usage
59
What is the best position for a patient in respiratory distress
Fowler’s or semi-Fowler’s (unless hypotensive)
60
What does the tripod position indicate
Severe respiratory distress (e.g. asthma COPD or epiglottitis)
61
When should you provide oxygen only
When breathing is adequate but the patient is in distress
62
When should you assist with ventilations
When breathing is inadequate or mental status is altered
63
What is a normal pulse oximetry reading
95–100%
64
At what SpO₂ should you consider administering oxygen
<94%
65
What can make pulse oximetry inaccurate
Hypoperfusion cold extremities carbon monoxide poisoning
66
When is CPAP indicated
Pulmonary edema COPD or asthma with moderate to severe distress
67
When is CPAP contraindicated
Altered LOC vomiting hypotension trauma
68
What is a common rescue inhaler EMTs may assist with
Albuterol (beta-2 agonist)
69
What are side effects of albuterol
Increased heart rate jitteriness anxiety
70
What does a “silent chest” in an asthma patient suggest
Complete airway obstruction – critical emergency
71
What oxygen device delivers 1–6 L/min at 24–44% oxygen
Nasal cannula
72
What oxygen device delivers 10–15 L/min up to 90–100% oxygen
Nonrebreather mask (NRB)
73
What oxygen device delivers 100% oxygen with good seal and reservoir
Bag-valve mask (BVM)
74
Why is reassessment important after treatment
To monitor for improvement or deterioration
