ANSWERS | 100% PASS
Which respiratory emergency presents with fever, cough, pleuritic chest pain, and
crackles that do not clear with coughing?
Asthma, pulmonary edema, chronic bronchitis OR Pneumonia - 🧠ANSWER
✔✔Pneumonia
Pneumonia presents with fever, cough, pleuritic chest pain, and lung sounds (such
as crackles) that do not usually clear with coughing..
Which respiratory emergency causes permanent abnormal enlargement of the air
spaces?
Asthma, pulmonary edema, emphysema, pulmonary embolus - 🧠ANSWER
✔✔Emphysema
Patients with emphysema have a permanent, abnormal enlargement of air spaces.
,Asthma, pulmonary edema, and pulmonary embolus do not result in permanent
alveolar changes.
A woman, age 53, presents to the emergency department with shortness of breath.
Which other finding should make you suspect that pulmonary embolism is the
cause?
Tachypnea, productive cough, calf pain, pleuritic chest pain - 🧠ANSWER ✔✔Calf

Which statement best defines ventilation?
Ventilation is the
1. mechanical flow of air into and out of the lungs.
2. mechanical perfusion of air into and out of the lungs

4. mechanical diffusion of air into and out of the lungs - 🧠ANSWER
✔✔Ventilation is the mechanical flow of air into and out of the lungs.
Negative intrathoracic pressure causes a vacuum effect, pulling air into the lungs
during inspiration. During expiration, the negative pressure decreases and air is
