The lungs are made up of how many lobes?

You arrive on scene to a car accident and are treating a 35-year-old patient. He is unresponsive and not breathing. You should open his airway by _______________.
Answer(s): D
The patient was in a car accident and injuries are not entirely known. The jaw thrust technique should be used to open the airway if a cervical injury is suspected.
You have a patient who has a history of asthma and is having shortness of breath. The patient has a doctor’s prescription to take 4 puffs of an Albuterol MDI every four hours as needed. Your local EMS policies allow you to help a patient self-administer the MDI. What side effect should you watch for from the MDI?
Albuterol, a bronchodilator used to treat asthma, may cause cardiovascular side effects such as increased heart rate.
You have an unresponsive patient with an intact gag reflex. You attempt to place a nasal airway in his right nostril, but you meet resistance and cannot insert. You should:
You do not want to use the wrong size airway or it will not be effective. Never force the airway in. An oral airway will not be tolerated with a patient with an intact gag reflex.
You’re treating an adult patient who is wearing a non-rebreather. The reservoir bag collapses on inspiration. What action(s) should you take?
A non-rebreather should be used with an oxygen flow rate high enough to inflate the reservoir bag, which is a minimum of 10 LPM. Switching to a nasal cannula will not deliver the same FiO2. The rate or depth a person inhales does not cause the reservoir bag to collapse.
Symptoms of asthma most often include:
Asthma causes a constriction of the airways and increased mucus production, which often causes shortness of breath, wheezing breath sounds, and a cough. Fever, vomiting, confusion and a runny nose are not typical.
You are treating a patient who is a construction worker and he fell from a residential rooftop. His breaths are shallow and irregular. What should you do?
Answer(s): A
When a patient has this type of extreme injury, a reduced LOC and shallow, inconsistent breathing patterns, BVM ventilations should be administered. Do not withhold ventilations in order to get a pulse oximeter reading. The NRB and nasal cannula are inappropriate for patients with insufficient ventilations.
When there isn’t enough oxygen being delivered to the body’s tissues, this is called:
Answer(s): C
Hypoxia is when there is insufficient oxygen delivery to the body’s tissues. Hypercarbia is when there are abnormally high carbon dioxide levels in the system. Shock and hypoperfusion both relate to inadequate tissue perfusion.
