Airway

The leaf-shaped structure located superior to the larynx is called the:

• vallecula
• cricoid ring
• thyroid cartilage
• epiglottis

All of the following can be found in the lower airway EXCEPT:

• the epiglottis
• alveoli
• the trachea
• bronchioles 

Which of the following factors will cause a decreased minute volume in an adult?

• increased tidal volume
• shallow breathing
• respirations of 20 breaths/min
• Slight decrease in respiratory rate

In contrast to inhalation, exhalation:

• requires muscular effort to effectively expel air from the lungs.
• occurs when the diaphragm lowers and expels air from the lungs.
• is a passive process caused by increased intrathoracic pressure.
• is an active process caused by decreased intrathoracic pressure

The hypoxic drive is influenced by:

• high blood O2 levels
• high blood CO2 levels
• low blood O2 levels
• low blood CO2 levels

Which of the following is a late sign of hypoxia?

• anxiety
• cyanosis
• tachycardia
• restlessness

The process of exchanging O2 and CO2 between the alveoli and the blood of the capillaries is called

• external respiration
• cellular metablosim
• ventilation
• alveolar ventilation

The primary waste product of aerobic metabolism is:

• lactic acid
• pyruvic acid
• Carbon Dioxide
• adenosine triphosphate

An unconscious patient found in the prone position must be placed in the supine position in case the patient:

• requires CPR
• begins to vomit
• regains consciousness
• has increased tidal volume

To select the appropriately sized OPA, measure from:

• corner of the mouth to the earlobe
• center of the mouth to the back of the ear
• corner of the mouth to the chin
• angle of the jaw to the base of the skull
