respiratory failure
respiratory arrest
respiratory compromise
- Signs of inadequte breathing include:
Your answer:
wheezing, crowing, or gurgling noises
cyanosis of the lips, ear lobes, or nail beds
the patient being unable to speak in full sentences
all of the above
- During your assessment of a 54-year-old male patient, you find that he is not breathing; your next step should be to:
Your answer:
begin providing artificial ventilations to the patient
begin chest compressions

4, 3, 1, and 2
2, 4, 3, and 1
2, 4, 1, and 3
- Signs of inadequate ventilation of an adult patient include:
Your answer:
a ventilation rate of approximately 12 per minute
failure of the patient's skin color to improve
a heart rate that returns to normal
the patient's chest rising and falling with each ventilation
- When high-concentration oxygen is attached to a pocket face mask, the concentration of oxygen delivered to the patient is approximately:
Your answer:

- All of the following are important features of bag-valve-mask systems (EXCEPT):
Your answer:
a 15/22mm respiratory fitting

- The most difficult part of delivering BVM artificial ventilations is:
Your answer:
obtaining an adequate mask seal
squeezing the bag completely
maintaining an open airway
preventing the patient from vomiting
- Oropharyngeal airways can be used on unconscious patients, except those who:
Your answer:
have a gag reflex
have a contagious respiratory disease
are under 8 years old
are in cardiac arrest
- If you do not have the proper size oropharyngeal airway to fit your patient:
Your answer:
use the next larger size
use the next smaller size
do not use one
use either a smaller or larger one
- The nasopharyngeal airway is popular because it:
Your answer:
can be used even if clear (CSF) fluid is seen in the nose or ears
is made of rigid clear plastic which is less likely to cause bleeding
often does not stimulate a gag reflex
comes in more sizes than the oropharyngeal airway
- Which of the following is true regarding suctioning a patient's airway?
Your answer:
Never suction for longer than 30 seconds
Suction only as you insert the catheter into the mouth
You may hyperventiliate a patient before and after suctioning
BSI precautions are not important if there is not visible blood
- The most popular type of suction tip in the prehospital setting is the Yankauer type because:
Your answer:
is has a larger bore than catheters
it comes in various sizes identified by a number "French"
it can be passed through an endotracheal tube
it is flexible and can be inserted deeper
- Patient conditions that may require supplemental oxygen include:
Your answer:
shock
head injury
broken bones
all of the above
- A nasal cannula should be used to deliver oxygen to a patient who:
Your answer:
has a chronic lung disease
will not tolerate a nonrebreather mask
is under 1 year old
uses a cannula with a home oxygen system
- Which of the following is true regarding the hazard of oxygen therapy?
Your answer:
Premature infants may develop eye damage if given too much oxygen
Patients with COPD may go into respiratory arrest after only a short time on high-concentration oxygen
Oxygen can react with some lubicants used with airway adjuncts and stimulate vomiting

Your answer:
2,000 psi
1,000 psi
1,500 psi
2,500 psi
- An insufficiency in the supply of oxygen to the body's tissues is called:
Your answer:

Your answer:
flow-restricted, oxygen-powered ventilation device
two-person BVM
one-person BVM
mounth-to-mask
- Nasopharyngeal airways must be lubricated to ease insertion; you should use:
Your answer:
any petroleum-based lubricant, suh as WD-40
any water-based lubricant
any silicone-based lubricant
petroleum jelly
- One method of determining which size nasopharyngeal airway to use is by:
Your answer:
comparing it to the diameter of the patient's little finger
measuring from the patient's nostril to the ear lobe
using the largest airway that will fit in the pateint's nostril without force
all of the above
