Q12. Your patient is a 58-year-old female. She called 911 complaining of difficulty breathing. During your initial assessment, you find that she is using accessory muscles to breathe at a rate of 20 shallow breaths per minute, and her SpO2 is 98% on room air. She has a high-pitched inspiratory stridor and is slightly cyanotic around her mouth. When you kneel down beside her you notice an ashtray piled high with cigarette butts. Which of the following is the most likely cause of her breathing difficulty, and what would be the most appropriate treatment?
- (A) She likely has COPD and the swelling of her lower airway passages is causing the stridor. High flow O2 or nebulizer with rapid transport.
- (B) She has CHF and the fluid backing up into her lungs is causing the obstruction of her lower airway. The smoking likely worsened the condition. High flow 02 via NRB and transport
- (C) She has an upper airway obstruction. Do abdominal thrusts until the obstruction is free and then apply high-flow O2 and transport
- (D) She has a foreign body obstruction in her upper airway. You should encourage her to cough in an attempt to dislodge it. Give high-flow O2 and rapid transport

- (A) Use the head tilt chin lift maneuver
- (B) Use the jaw thrust maneuver again
- (C) Move the patient to a supine position and again attempt to open his airway with the jaw thrust maneuver
- (D) Put in an OPA and prepare to suction
Q14. With regard to the airway and breathing of a child, which of the following statements is most accurate?
- (A) You should role up a towel to 1 inch thick and place it under the child’s neck when in need of assisting ventilations
- (B) Airway adjuncts should not be used in children as a child’s airway is not shaped as an adults
- (C) Use of a pediatric resuscitation tape can aid in the selection of the correct equipment
- (D) A child who is breathing adequately will use accessory muscles
Q15. What are the main differences between a child’s airway and an adult’s airway?
- (A) A child’s airway is shorter and more compact than an adult’s, making it easier to visualize the vocal cords
- (B) An adult’s airway is more narrow than a child’s airway
- (C) A child’s airway is narrower at the Cricoid ring and the tongue is larger in proportion to the mouth
- (D) There is no difference. Children’s airways are just like adults
