Question 1

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.

Accepted Answer

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

Question 2

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

Accepted Answer

A. Carbon monoxide poisoning

Question 3

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.

Accepted Answer

A. nonrebreathing mask.

Question 4

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.

Accepted Answer

A. a lower airway obstruction.

Question 5

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.

Accepted Answer

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

Question 6

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

Accepted Answer

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

Question 7

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.

Accepted Answer

A. Cheyne-Stokes respirations.

Question 8

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.

Accepted Answer

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

Question 9

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

Accepted Answer

D. ventilation.

Question 10

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.

Accepted Answer

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

Question 11

When testing a mechanical suctioning unit, you should turn on the device, clamp the tubing, and ensure that it generates a vacuum pressure of more than: Select one: A. 300 mm Hg. B. 200 mm Hg. C. 400 mm Hg. D. 100 mm Hg.

Accepted Answer

A. 300 mm Hg.

Question 12

Which of the following is the MOST reliable indicator of adequately performed bag-valve-mask ventilation in an apneic adult with a pulse? Select one: A. Twenty breaths/min being delivered to the adult B. Consistently increasing heart rate C. Decreased compliance when squeezing the bag D. Adequate rise of the chest when squeezing the bag

Accepted Answer

D. Adequate rise of the chest when squeezing the bag

Question 13

Which of the following patients is breathing adequately? Select one: A. A conscious male with respirations of 18 breaths/min and reduced tidal volume B. A conscious male with respirations of 19 breaths/min and pink skin C. An unconscious 52-year-old female with snoring respirations and cool, pale skin D. A conscious female with facial cyanosis and rapid, shallow respirations

Accepted Answer

B. A conscious male with respirations of 19 breaths/min and pink skin

Question 14

Which of the following patients should you place in the recovery position? Select one: A. A 19-year-old conscious male with a closed head injury and normal respirations B. A 31-year-old semiconscious male with low blood sugar and adequate breathing C. A 40-year-old conscious female with a possible neck injury and regular respirations D. A 24-year-old unconscious female who overdosed and has a reduced tidal volume

Accepted Answer

B. A 31-year-old semiconscious male with low blood sugar and adequate breathing

Question 15

Which of the following statements regarding breathing adequacy is correct? Select one: A. Patients breathing shallowly may require assisted ventilation despite a normal respiratory rate. B. A patient with slow respirations and adequate depth will experience an increase in minute volume. C. The single most reliable sign of breathing adequacy in the adult is his or her respiratory rate. D. Patients with a grossly irregular breathing pattern usually do not require assisted ventilation.

Accepted Answer

A. Patients breathing shallowly may require assisted ventilation despite a normal respiratory rate.
