EMT Airway, Respiration, & Ventilation

1

100

Inconsistent crackling on auscultation indicates:

• Rales
• Stridor
• Wheezing
• Rhonchi

• Rales

200

Total lung volume is calculated by:

• Inspiratory Reserve Volume + Expiratory Reserve Volume
• Tidal Volume + Reserve Volume
• Vital capacity + Residual volume
• Residual Volume + Tidal Volume

• Vital capacity + Residual volume

300

Advanced Airways:

• Are always located above the vocal cords
• Include OPA’s and NPA’s
• Can be used on a pt with a gag-reflex
• Include Supraglottic and Endotracheal Tubes

• Include Supraglottic and Endotracheal Tubes

400

After a car accident, you suspect Jason has increased ICP due to his Cheyne Stokes respirations, made obvious by:

• Alternating periods of fast breathing and apnea
• Alternating periods of gasping and apnea
• Alternating periods of gradual slow to fast breathing and apnea
• Deep, rapid breathing

• Alternating periods of gradual slow to fast breathing and apnea

500

Airway adjuncts are used in conjunction with a:

• Nasal Cannula
• Non-Rebreather
• Bag Valve Mask
• CPAP/BIPAP

• Bag Valve Mask

100

Respiration is driven by

• Oxygen
• Nitrogen
• Carbon Monoxide
• Carbon Dioxide

• Carbon Dioxide

200

Crackling in the lungs indicates:

• Upper airway obstruction
• Lower airway obstruction
• Fluid in the lungs
• Trauma

• Fluid in the lungs

300

NPA’s are used for patients:

• With a gag-reflex

400

After crashing his care into Jason’s you suspect Chris had a stroke due to his Biot’s breathing, made obvious by:

• Alternating periods of fast breathing and apnea
• Alternating periods of gradual slow to fast breathing and apnea
• Deep, rapid breathing
• Fast, shallow breathing

• Alternating periods of fast breathing and apnea
• Biot's breathing is identified as alternating periods of fast breathing and apnea, usually indicative of a neurological issue like stroke.

500

 Jason thinks his shortness of breath may be pneumonia, due to the presence of:

• Fever
• Rash
• Difficulty swallowing
• Erection

• Fever

ALS

100

An Indication for ET tube placement is:

• Impending airway failure
• A feeling of impending doom
• The need for short term ventilation
• Choking

• Impending airway failure

200

Before intubation, be sure to:

• Preoxygenate the patient
• Position the airway
• Check your equipment
• All of the above

• All of the above

300

Laryngoscopes are used to:

• Move the tongue out of the way
• Lift the epiglottis
• Position the airway
• Oxygenate the patient

• Lift the epiglottis

400

Cricothyrotomy is used:

• When an advanced airway cannot be placed
• In persistent obstruction
• Only on patients with a tracheostomy
• In obstruction not cleared by manual positioning

• In persistent obstruction

500

The Mallampati Classification involves looking at the:

• Mouth
• Nose
• Throat
• Sinuses

• Mouth

100

Chris thinks Jason’s SOB is from Pulmonary Edema, due to his:

• Fever
• Congestion
• Pain
• Impotence

• Congestion

200

If the thoracic cavity increases in volume, the intrathoracic pressure will

• Increase
• Decrease
• Invert
• Exhale

• Decrease

300

Fluid buildup in the lungs is dangerous because it:

• Impedes airflow through the bronchioles
• Increases intrathoracic pressure
• Results in pulmonary embolus
• Impedes gas exchange in the alveoli

• Impedes gas exchange in the alveoli

400

When the diaphragm contracts air flows:

• From lower concentration to higher concentration
• Into the lungs
• Out of the lungs
• Out of the alveoli

• Into the lungs

500

Perfusion is:

• The movement of air in and out of the lungs
• The delivery of blood to the tissues
• The movement of molecules from areas of high to low concentration
• The delivery of oxygen to the patient

• The delivery of blood to the tissues

5

100

A device that uses litmus paper to detect CO2 is:

• The CO2 nasal cannula sampling line
• The end tidal CO2 (ETCO2)
• In-line CO2
• Colorimetric CO2 detector

• Colorimetric CO2 detector

200

After breathing out all he can, the air left in Chris’ lungs is called

• Reserve volume
• Residual volume
• Vital capacity
• Tidal Volume

• Residual volume

300

A patient has a patent airway if:

• They can speak
• They are conscious
• They can’t breathe
• They have a gag reflex

• They can speak

400

Signs and symptoms of pulmonary embolism include:

• Normal breath sounds
• Hypercapnia
• Progressive onset SOB
• No breath sounds on one side

• Normal breath sounds

500

A pneumothorax is treated by all of the following except:

• Supportive care
• 02 administration
• CPAP/BIPAP
• Needle Decompression

• CPAP/BIPAP
