What is the danger that an altered mental status can pose to a patient's breathing?

Which of the following is a sign of an inadequate airway?

A. equal expansion of both sides of the chest when patient inhales B. typical skin coloration C. regular chest movements D. nasal flaring D.

For life to be maintained, a balance of oxygen and carbon dioxide is needed. The condition when oxygen levels are low is called:

A. hypoxia B. hyperventilation C. hypotension D. hypercarbia A.

Concerning the use of humidified oxygen, which of the following is true?

A. it is not of great benefit during short transports but can make the patient more comfortable B. the water reservoir should be changed on a weekly basis C. the water in the reservoir should be treated with chlorine tablets to prevent the growth of bacteria D. it should be used when assisting ventilations with a bag-valve-mask device. A.

Why is inhalation described as an active process?

A. it requires chest muscles to relax and use energy to more, creating a positive pressure B. it requires the diaphragm to relax and use energy to move, creating a positive pressure C. it requires chest muscles to contract and use energy to move, creating a negative pressure. D. it uses oxygen to assist chest muscles to contract, creating a negative pressure. C

You are ventilating an 85-year-old make without difficulty. A nurse tells you that the patient has dentures. To ensure a good mask seal you should:

A. leave the dentures in place B. remove the dentures C. tape the dentures in place D. use an infant mask over the nose A

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:

A. perform chest thrusts B. finger sweep the airway C. ease the head forward a little D. tilt the head back further C.

The high-pitched sound caused by an upper airway obstruction is known as:

A. rales B. stridor C. gurgling D. rhonchi B

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 has a yellow stripe around it instead of a green one but was stored with the green cylinders. You are unable to get the regulator to seat properly and it will not turn. You should:

A. remove the cylinder and get a green cylinder B. put the old cylinder back on the truck C. attempt to force the regulator onto the cylinder D. replace the oxygen regulator with a new one A

Which of the following is true concerning the procedure for inserting a nasopharyngeal airway (NPA)?

A. the bevel should be turned toward the nasal septum B. the length of the device is not as important as it is with OPA C. if a water-soluble lubricant is not available, a silicon spray can be substituted D. it can only be placed in the right nostril A

All of the following can result in airway obstructions, except:

A. the tongue B. burns C. infections D. facial traumas A.

Which of the following is a disadvantage of oropharyngeal airways (OPAs)?

A. they cannot be used in a patient with the gag reflex B. they require the use of a water-soluble lubricant C. they cannot be used in patients with a suspected skull fracture D. they do not come in pediatric sizes A

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?

A. use a nasal cannula instead B. Consult with medical control about restraining the patient C. Have her breathe into a paper bag to control her hyperventilation D. do not make further attempts to administer oxygen as it will only agitate the patient further. A.

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?

A. using large bore suction tubing without a tip or catheter attached B. using a rigid pharyngeal suction tip C. using a 14 French suction catheter D. irrigating the mouth with sterile water to dilute the material before suctioning. A

When does respiratory distress change to respiratory failure?

A. when the respiratory challenge continues, the systems cannot keep up with the demand and skin color and mental status change B. when the respiratory challenge continues, the systems fail with the demand for oxygen, pupils dilate, and the skin becomes hot and dry. C. when the patient who is short of breath, with noisy respiration, presents in the tripod position but then suddenly has the condition clear up and return to normal D. when the compensatory mechanism is no longer needed and the patient goes into arrest A.

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?

A. you should increase the patient's oxygen flow rate until his respiratory rate decreases and then resume oxygen administration at 2 liters per minute B. you should not increase the patient's oxygen flow rate because of his likely dependence on a hypoxic drive to stimulate breathing C. 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 D. 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 D.
