Chapter 10: PreTest Flashcards
You notice the apneic patient’s abdomen getting larger during artificial ventilation. What could have prevented this?
Using an airway adjunct when ventilating
The reservoir bag on a nonrebreather mask should:
not completely empty during inhalation.
Ventilation is:
breathing in and out.
You are treating a patient who has taken too much of her pain-relieving narcotic. She is breathing very slowly with minimal chest rise. Which device would not be appropriate to administer oxygen to this patient?
Nonrebreather mask or nasal cannula
In a patient in respiratory distress who is breathing adequately, you would expect:
an elevated rate of breathing but adequate minute volume.
For two-rescuer BVM when no trauma is suspected, you would:
Place the patient in the head-elevated, sniffing position.
You are treating a patient who needs supplemental oxygen but who will not tolerate the nonrebreather mask that you would like to use. What should you do?
Switch to a nasal cannula.
A number of different oxygen cylinders are available. Which of the following is true?
The oxygen used in emergency care is stored under pressure.
Which of the following is a complication of using a FROPVD on an adult patient?
Decreased cardiac output can occur.
Oxygen should never be used:
around open flames.
Dead air space is found in the:
trachea and bronchi.
What is the approximate amount of oxygen in a portable D cylinder?350 liters
350 liters
For a patient with a stoma, the first step of artificial ventilation using a BVM is to:
clear any mucus or secretions from the stoma.
For a person experiencing an asthma attack, which of the following statements is true, assuming a fixed respiratory rate?
Both tidal volume and minute volume are decreased from normal during the asthma attack.
When ventilating with a bag-valve-mask device, what is one action you would take with suspected spinal injury that you would not do otherwise?
Do not tilt the head or neck when bringing the jaw up to the mask.
The rate of artificial ventilations through a stoma is based on:
the patient’s age.
Which patient is breathing adequately?
A patient in respiratory distress
Which of the following most likely indicates hypoxia?
Bluegray skin
A patient begins vomiting during positive pressure ventilation using a bag-valve mask. You should:
immediately stop ventilation and suction the airway.
You most likely should administer oxygen by NRB mask to a patient:
who complains of shortness of breath.
A person breathing too slowly will have:
a decreased minute volume.
Never use adhesive tape on an oxygen tank, as it may cause:
a fire.
For a patient with rapid ventilations, you should:
deliver ventilations at the same time as the patient’s inhalations.
The product of tidal volume and ventilation rate is:
minute volume.
A partial rebreather mask is different from a nonrebreather mask because it:
lacks a one-way valve in the opening to the reservoir bag.
A process by which molecules move from an area of high concentration to an area of low concentration is called:
diffusion.
A negative side effect of positive pressure ventilation is:
decreasing cardiac output.
Which of the following patients would be the most likely to receive humidified oxygen?
A patient with COPD who is being transferred to a pulmonary center in another part of the state
Both pulmonary and cellular respiration primarily involve:
blood and the diffusion of oxygen.
The optimum flow rate of oxygen delivered via nonrebreather mask is:
12-15 liters a minute.
Why does air enter the lungs during inhalation?
Negative pressure is created inside the lungs.
When compensation for increasing oxygen demand fails and the body’s metabolic needs are not met, hypoxia becomes profound, carbon dioxide builds to dangerous levels, and the muscles used for increased respiration begin to tire. This state is called:
respiratory failure.
Which of the following has the most significant impact on regulation of breathing?
Carbon dioxide levels
What oxygen delivery device can provide specific concentrations of oxygen?
Venturi mask
Your patient is very sweaty, speaking only in sentences of one or two words. What would you expect could happen to this patient without intervention?
Becomes sleepy and unarousable
Which patient would most likely benefit from a humidifier on an oxygen cylinder?
A 7-year-old patient
A 35-year-old female patient is alert and calm, and although she is experiencing increased breathing effort, she can speak in full sentences. This patient should receive:
oxygen via nonrebreather mask or nasal cannula.
Increased work of breathing or a sensation of shortness of breath is:
respiratory distress.
When inspirations are prolonged, this indicates:
an upper airway obstruction.
When should the EMT consider humidifying oxygen for a patient?
When the oxygen will be administered over a long period of time
When the diaphragm contracts, the patient:
inhales.
Your patient has an alert mental status, a normal skin color, and a pulse oximetry reading within normal limits. This patient is:
breathing adequately.
A pressure regulator must be connected to an oxygen cylinder to provide a safe working pressure of:
30-70 psi.
What is normally the maximum flow setting for oxygen delivery with a nonrebreather mask?
15 lpm
What is the universal color for medical-grade oxygen tanks?
Green
Which of the following patients is at risk for failure of the cardiopulmonary system?
A patient with severe asthma or COPD
The mechanics of breathing would be disrupted in a patient:
who sustained painful chest wall injuries.
What is the cause of gastric distention during ventilation?
Air is pushed through the esophagus during ventilation.
After correct placement of an endotracheal tube has been confirmed, you note that the 22-cm mark is at the patient’s teeth. A short time later, you notice that the 21-cm mark is now at the patient’s teeth. You should:
notify the paramedic immediately.
An advanced airway device that requires visualization of the glottic opening is:
endotracheal intubation.
