Chapter 10 Quiz Flashcards

A 19-year-old female is found unconscious by her roommate. Your primary assessment reveals that her breathing is inadequate. As you insert an oropharyngeal airway, she begins to gag violently. You should:
Select one:
A. select a smaller oropharyngeal airway and attempt to insert it.
B. remove the airway and be prepared to suction her oropharynx.
C. insert the airway no further but leave it in place as a bite block.
D. continue to insert the airway as you suction her oropharynx.

B. remove the airway and be prepared to suction her oropharynx.

A man was found unresponsive in his bed at home. There is no evidence of injury and the patient's medical history is not known. The patient's face is cyanotic, yet the pulse oximeter reads 98%. Which of the following would MOST likely explain this? Select one: A. Carbon monoxide poisoning B. Severe pulmonary edema C. Increased body temperature D. His extremities are cold

A. Carbon monoxide poisoning

A patient who is suspected of being hypoxic and is breathing adequately should be given supplemental oxygen with a: Select one: A. nonrebreathing mask. B. nasal cannula. C. bag-valve mask. D. mouth-to-mask device.

A. nonrebreathing mask.

During your assessment of a patient with respiratory distress, you hear wheezing when listening to breath sounds. This indicates: Select one: A. a lower airway obstruction. B. secretions in the airway. C. swelling of the upper airway. D. fluid in the alveoli.

A. a lower airway obstruction.

How does CPAP improve oxygenation and ventilation in patients with certain respiratory problems?
Select one:
A. It decreases intrathoracic pressure, which allows more room for lung expansion.
B. It forces the alveoli open and pushes oxygen across the alveolar membrane.
C. It pushes thick, infected pulmonary secretions into isolated areas of the lung.
D. It prevents alveolar collapse by pushing air into the lungs during inhalation.

B. It forces the alveoli open and pushes oxygen across the alveolar membrane.

In which of the following patients would the head tilt–chin lift maneuver be the MOST appropriate method of opening the airway?
Select one:
A. A 50-year-old male who is unconscious following head trauma
B. A 24-year-old male who is found unconscious at the base of a tree
C. A 45-year-old male who is semiconscious after falling 20 feet
D. A 37-year-old female who is found unconscious in her bed

D. A 37-year-old female who is found unconscious in her bed

Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called: Select one: A. Cheyne-Stokes respirations. B. ataxic respirations. C. eupneic respirations. D. agonal respirations.

A. Cheyne-Stokes respirations.

The nasopharyngeal airway is MOST beneficial because it:
Select one:
A. can maintain a patent airway in a semiconscious patient with a gag reflex.
B. is generally well tolerated in conscious patients with an intact gag reflex.
C. effectively maintains the airway of a patient in cardiopulmonary arrest.
D. can effectively stabilize fractured nasal bones if it is inserted properly.

A. can maintain a patent airway in a semiconscious patient with a gag reflex.

The physical act of moving air into and out of the lungs is called: Select one: A. diffusion. B. respiration. C. oxygenation. D. ventilation.

What occurs when a patient is breathing very rapidly and shallowly?
Select one:
A. Air is forcefully drawn into the lungs due to the negative pressure created by the rapid respirations.
B. Air moves primarily in the anatomic dead space and does not participate in pulmonary gas exchange.
C. Minute volume increases because of a marked increase in both tidal volume and respiratory rate.
D. The majority of tidal volume reaches the lungs and diffuses across the alveolar–capillary membrane.

B. Air moves primarily in the anatomic dead space and does not participate in pulmonary gas exchange.
