Motor vehicle collision
Seizure
Cardiac arrest
All of the above
You are ventilating a cardiac arrest patient when he begins to vomit copious amounts of large pieces of undigested food. Which of the following would be most effective in clearing the airway?
Using a 14 French suction catheter
Using a rigid pharyngeal suction tip
Using large bore suction tubing without a tip or catheter attached
Irrigating the mouth with sterile water to dilute the material before suctioning
Which of the following is the correct method of suctioning?
Begin suctioning as you insert the suction tip or catheter into the mouth.
Insert the catheter or tip to the desired depth prior to applying suction.
Suction intermittently, both while inserting and withdrawing the suction tip or catheter.
Suction continuously, both while inserting and withdrawing the suction tip or catheter.
You have performed a head tilt-chin lift maneuver on a 17-month-old boy and are attempting to ventilate him with a bag-valve mask. You are experiencing a lot of resistance with each breath and the chest is barely rising. Prior to attempting ventilations again, you should:
Finger sweep the airway
Perform chest thrusts
tilt the head back further
ease the head forward a little
What are the signs of hypoxia?
Cyanosis (blue or gray skin) and deterioration of the patient's mental status
Irreversible shock caused by the lack of blood flowing to the vital organs like the brain and heart
Warm dry skin, difficulty breathing, and hypertension
Disease process that robs the patient of adequate breathing and perfusion
Why is inhalation described as an active process?
It requires the diaphragm to relax and use energy to move, creating a negative pressure.
It requires the diaphragm to contract and use energy to move, creating a positive pressure.
It requires chest muscles to contract and use energy to move, creating a negative pressure.
It requires chest muscles to relax and use energy to move, creating a positive pressure.
The normal urge to breathe is stimulated by chemoreceptors that measure changing levels of what two gases?
Carbon monoxide and oxygen
Hydrogen and carbon monoxide
Carbon dioxide and oxygen
Hydrogen and carbon dioxide
Which of the following describes why fast respiration may decrease minute volume?
The rate causes turbulence in the trachea that increases the friction and decreases the amount of air movement.
The lungs may not have adequate time to fill and exchange gas.
It is due to the delay in the movement of the intercostal muscles and the pleural space.
The rate does not decrease minute volume; it actually increases it.
A 16-year-old patient presents with labored breathing and increased respiratory rate, increased heart rate, and leaning forward with his hands on his knees. His skin is a normal color and his pulse oximetry is 96. This patient is suffering from respiratory:
failure
distress
hypoxia
arrest
You have arrived at the scene of a call for a "man down." As you enter the residence you note that your patient is a male in his mid-60s who is awake but does not seem to acknowledge your presence. He is perspiring profusely, has cyanosis of his ears and lips, and has rapid, shallow respirations. Which of the following should you do first?
Assist ventilations with a bag-valve mask and supplemental oxygen.
Check for a radial pulse.
Obtain the patient's medical history.
Listen to his lung sounds.
You are aggressively ventilating an adult patient with a bag-valve mask when you notice that his previously strong pulse is getting weaker. You should:
reduce the concentration of oxygen.
reduce the volume of the ventilations.
begin chest compressions.
increase the concentration of oxygen.
You and your EMT partner are preparing to ventilate an elderly non-trauma patient who has a stoma. Your partner performs the head-tilt, chin-lift maneuver and you ask him to return the patient's head to a neutral position. "Why? This is not a pediatric patient!" your partner protests. What would you say?
Elderly patients should never have their heads tilted back because spinal curvatures are common and can prevent airway positioning.
Using the head-tilt, chin-lift prior to clearing any mucus plugs from the stoma can cause airway occlusion.
It is not necessary to position the airway of a stoma breather when providing ventilations.
Stoma breathers should only have their airways positioned after placement of the ventilation device.
Your patient is a 55-year-old man with a history of chronic bronchitis. You have been called to his home today because of an increase in his level of respiratory distress. The patient is on 2 liters per minute of oxygen by nasal cannula at home. Your assessment reveals difficulty speaking due to shortness of breath, leaning forward to breathe, a productive cough, and a respiratory rate of 32 per minute. Which of the following is true concerning the best course of action for this patient?
Because increased blood levels of carbon dioxide are the primary stimulus to breathe, you should encourage the patient to rebreathe his exhaled air from a paper bag.
You should increase the patient's oxygen flow rate until his respiratory rate decreases and then resume oxygen administration at 2 liters per minute.
You should increase the patient's oxygen flow rate to deliver adequate amounts of oxygen to his tissues. If his respiratory rate decreases, you can assist him with a bag-valve-mask device.
You should not increase the patient's oxygen flow rate because of his likely dependence on a hypoxic drive to stimulate breathing.
You are transporting a 44-year-old female with chest pain and sudden respiratory distress. She is agitated, anxious, and refuses to have a nonrebreather mask applied. Which of the following is the best option?
Use a nasal cannula instead.
Have her breathe into a paper bag to control her hyperventilation.
Consult with medical control about restraining the patient.
Do not make further attempts to administer oxygen as it will only agitate the patient further.
The oxygen flow rate for a nasal cannula should not exceed ________ liters per minute.

You are attempting to replace the oxygen cylinder in your truck. After removing the regulator from the old cylinder, removing the old cylinder, and placing the new cylinder in the oxygen compartment, you attempt to connect the regulator. The new cylinder is yellow rather than green, but it was stored with the green cylinders. You are unable to get the regulator to seat properly and it will not turn. You should:
remove the yellow cylinder and get a green cylinder.
attempt to force the regulator onto the cylinder.
replace the oxygen regulator with a new one.
put the old cylinder back on the truck.
The safe residual for an oxygen cylinder is ________ psi.
500
300
200
1,000
Which of the following is necessary to deliver oxygen to patients at a safe pressure?
Regulator
Float ball
Filter
Flowmeter
The paramedic is intubating a patient and asks you to assist by gently pressing your thumb and index finger to either side of the throat just over the patient's Adam's apple. As you press, you gently direct the throat upward and to the patient's right. What is the purpose of this maneuver?
It keeps the tube from becoming displaced and entering the esophagus.
It pushes the patient's vocal cords into the paramedic's view.
It lessens the patient's gag reflex and eases tube insertion.
It prevents the tube from entering the right mainstem bronchus.
