Ch 10 quiz Flashcards
The high-pitched sound caused by an upper airway obstruction is known as:
stridor
Which of the following structures is found in the lower airway?
Bronchi
Perhaps the simplest way to determine if a patient has a patent airway is to:
say “hello”
Which of the following patients should NOT have their airway opened using a head-tilt, chin-lift maneuver?
A homeless person of undetermined age found lying unresponsive in an alley with no bystanders.
When inserting an oropharyngeal airway, how many degrees do you need to rotate the airway so the tip is pointing down into the patient’s pharynx?
180
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:
ease the head forward a little.
You are ventilating an 85-year-old male without difficulty. A nurse tells you that the patient has dentures. To ensure a good mask seal, you should:
leave the dentures in place.
For life to be maintained, a balance of oxygen and carbon dioxide is needed. The condition when oxygen levels are low is called:
hypoxia
What are the signs of hypoxia?
Cyanosis (blue or gray skin), deterioration of patient’s mental status
In assessing a patient’s breathing, what is your first question?
Is he breathing?
The process of air moving in and out of the chest is called:
ventilation.
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.
The movement of oxygen and carbon dioxide across the cell membranes from the capillaries is called:
internal respiration.
When does respiratory distress change to respiratory failure? how can you tell?
When the respiratory challenge continues, the systems cannot keep up with the demand, and skin color and mental status change.
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.
What is NOT one of the basic parts of a bag-valve-mask system?
15/25 respiratory fitting
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?
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.
A nonrebreather mask at 12 to 15 liters per minute will generally provide the patient what percentage of oxygen?
80-100
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.
Which of these patients would require a tracheostomy mask for supplemental oxygen administration?
A patient with a stoma
Which of the following is acceptable for maintaining a seal between an oxygen cylinder and regulator?
gasket
