Airway Management Review

The exchange of oxygen and carbon dioxide between the systemic circulation and the cells of the body is: 

• Anaerobic metabolism 

• Internal respiration 

• External respiration 

• Metabolic respiration 

The narrowest portion of the adult trachea is the: 

• Carina 

• Larynx 

• Cricoid Cartilage

• Glottic opening 

Which of the following patients would benefit most from the use of CPAP? 

• A patient with signs of shock and two-word dyspnea who cannot hold his head up 

• A patient with COPD c/o of a stomach bug 

• A patient with rales and pedal edema struggling to breath but alert 

• A patient who suffered a blow to the chest, is in respiratory distress and has unequal chest wall movement 

You are responding to a 68 y/o male patient who is complaining of SOB. The patient is tripoding and anxious. The patient answers questions by nodding or shaking his head, though he seems slow to respond and confused at times. His vitals are RR 30/min and shallow, SPO2 90%, P134. You should: 

• Assist ventilations, evaluate perfusion, and transport 

• Give supplemental O2 via NRB, listen to breath sounds, and treat for shock 

• Apply a nasal cannula at 6lpm, assess the skin, transport 

• Open the airway, suction, and place patient on a NRB at 15 lpm 

Which of the following is not a contraindication to the use of CPAP?

• Cardiogenic shock 

• Recent GI surgery 

• Closed head injury 

• Systolic BP of 102 

Why is hypotension a risk of CPAP use?

• As intrathoracic pressure builds, venous blood return to the heart meets resistance and preload drops 

• Increased intrapulmonary pressure forces fluid out of the alveoli causing a drop in the amount of fluid in the vasculature 

• Increased intrathoracic pressure forces vasodilation and preload decreases as a result 

• Cardiac output is decreased due to an overall reduction of systemic circulating volume when CPAP is applied 

Which of the following structures is designed to increase the surface area of the nasal passage to allow more time for warming, humidifying, and filtrating inspired air?

• Turbinates

• Visceral Pleura

• Nasal Cincher

• Surfactant

The manubrium is:

• The bottom point of the sternum

• The point of bifurcation of the trachea

• The top portion of the sternum

• None listed

All of the following are within the mediastinum except: Select all that apply.

• Lungs

• Heart

• Great Vessels

• Esophagus

• Trachea

Which of the following is the process by which we naturally breath?

• Positive Pressure Ventilation

• Diffusion

• Negative Pressure Ventilation

• Oxygenation

• Respiration
