1. In which of the following patients would the use of a nasopharyngeal airway be most appropriate?

2. Which of the following is true about the lung volumes of a person with COPD?

3. You are doing an interfacility transport of a patient who was intubated prior to your arrival at the sending facility. The chest X-ray from the previous facility confirmed proper placement before you departed. During transport, the patient’s pulse oximetry begins to drop, and the EtCO₂ waveform is slightly  lower than earlier. The patient still has a pulse.
The ETT of the patient is confirmed as still being in the trachea. It has been suctioned, all equipment is functioning properly, and O₂ is flowing at 15 LPM. However, the pulse oximetry is continuing to drop, and the EtCO₂ is starting to increase. It is notably harder to ventilate the patient, and the left side of the chest is not rising as it was earlier in the transport. What should you do next?

4. A patient who twisted his or her ankle while running is found to be tachypneic during your assessment. Possible reason(s) for this include:

6. Which of the structures listed above is/are part of the upper airway?

7. A 42-year-old female patient is complaining of a sudden onset of dizziness that started while at rest and is constant but not worsening with a change in position. She has been on bed rest for the past 2 weeks after an infection to her incision for a total knee replacement. Her vital signs are HR: 108; RR: 24; SpO₂: 91% (on 15 LPM O₂ via mask); BP: 132/88. Her lung sounds are clear in all fields and equal bilaterally. Her skin color and temperature are unremarkable. She has not passed out, and her blood sugar is within normal limits.
This patient is most likely having a problem with:

9. For a 55-year-old male patient in status asthmaticus on 10 LPM O₂ via a nebulizer who has already received 2 nebulized albuterol treatments and 500 mcg of ipratropium bromide, which of the following would be the next best treatment option?

Which of the following sets of signs and symptoms would you expect to find to help confirm your diagnosis here?

11. You have arrived at the home of a 3-year-old female who is in respiratory distress. She is seated in a tripod position and drooling, stating she is unable to swallow. Her mother indicates that she has recently been sick with a strep throat infection. You suspect your patient has:

12. I.     Trachea
II.    OropharynxvIII.   Bronchioles
IV.   Bronchi
V.    Cricoid cartilage
Place these 5 structures in order according to the way inhaled air would encounter them.
