Quiz 7 (Chapter 10) Flashcards
Which of the following statements best describes the exchange of gas in the alveoli?
Air moves into the alveoli, blood is transported by the pulmonary capillaries, and diffusion occurs.
Which of the following is acceptable for maintaining a seal between an oxygen cylinder and regulator?
Gasket
Which patient should definitely be administered supplemental oxygen without positive pressure?
A patient in mild respiratory distress
Of the three types of oxygen flowmeters, which one can only be used upright?
Pressure-compensated flowmeter
If your patient has excessive gastric distention due to PPV, what piece of equipment is most important to have readily available?
The suction unit
What is the maximum flow rate that you would administer by nasal cannula?
6 lpm
The movement of oxygen and carbon dioxide between the alveoli and circulating blood is called:
pulmonary respiration.
The function of the respiratory system in the respiratory process is to:
move air in and out of the alveoli.
Forcing air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing is called:
artificial ventilation.
At the point at which the patient’s body has become acidotic from the retention of too much carbon dioxide and from anaerobic metabolism (metabolism without enough oxygen present), and he is growing tired, the patient is in:
respiratory failure.
For single-rescuer BVM ventilation, begin by:
positioning yourself at the patient’s head and opening the airway.
Which of the following is necessary to deliver oxygen to patients at a safe pressure?
Regulator
Your patient is a motorcyclist who was ejected after striking a guard rail. The patient is unresponsive to painful stimuli and is breathing shallowly six to eight times per minute. Which of the following should you do first?
Use a bag-valve mask with supplemental oxygen.
To inflate the reservoir bag of a nonrebreather mask, use your finger to cover the:
exhaust port.
A permanent surgical opening in the neck through which the patient breathes is a:
stoma.
Your patient is a 65-year-old male with a history of COPD. He is sitting up and complaining of a severe shortness of breath. You should:
apply a nonrebreather mask giving 15 lpm of oxygen.
What signs and symptoms would indicate inadequate breathing in a patient?
Increased effort to breathe, cyanosis, clammy skin, altered mental status
If an oxygen humidifier is going to be used in the ambulance for a long trip, the EMT should:
use fresh water in a clean reservoir.
For life to be maintained, a balance of oxygen and carbon dioxide is needed. The condition when oxygen levels are low is called:
hypoxia.
When there are two rescuers dedicated to the airway, the most appropriate device to use on a nonbreathing patient would be:
a bag-valve-mask device.
The safe residual for an oxygen cylinder is ________ psi.
200
Which of the following devices should be used by two rescuers whenever possible?
BVM
By using airway adjuncts while ventilating a patient and using proper head-positioning and airway-opening techniques, you may avoid:
gastric distension
A ________ is not typically used in the prehospital setting for oxygen administration.
partial rebreather mask
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 pushes the patient’s vocal cords into the paramedic’s view.
While ventilating an intubated patient with a bag-valve-mask-unit, you notice increased resistance to the ventilations. This may indicate that:
air is escaping through a hole in the lung and filling the pleural space.
What two measurements are multiplied to calculate the minute volume?
Tidal volume and respiratory rate
