Chapter 10 Quiz Flashcards
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?
A. Severe pulmonary edema
B. His extremities are cold
C. Carbon monoxide poisoning
D. Increased body temperature
C. Carbon monoxide poisoning
Which of the following patients should you place in the recovery position?
A. A 19-year-old conscious male with a closed head injury and normal respirations
B. A 40-year-old conscious female with a possible neck injury and regular respirations
C. A 24-year-old unconscious female who overdosed and has a reduced tidal volume
D. A 31-year-old semiconscious male with low blood sugar and adequate breathing
D. A 31-year-old semiconscious male with low blood sugar and adequate breathing
What occurs when a patient is breathing very rapidly and shallowly?
A. Minute volume increases because of a marked increase in both tidal volume and respiratory rate.
B. Air is forcefully drawn into the lungs due to the negative pressure created by the rapid respirations.
C. Air moves primarily in the anatomic dead space and does not participate in pulmonary gas exchange.
D. The majority of tidal volume reaches the lungs and diffuses across the alveolar–capillary membrane.
C. Air moves primarily in the anatomic dead space and does not participate in pulmonary gas exchange.
Which of the following statements regarding normal gas exchange in the lungs is correct?
A. The actual exchange of oxygen and carbon dioxide occurs in the capillaries.
B. Blood that returns to the lungs from the body has low levels of carbon dioxide.
C. The oxygen content in the alveoli is highest during the exhalation phase.
D. Oxygen and carbon dioxide diffuse across the alveolar walls and capillaries.
D. Oxygen and carbon dioxide diffuse across the alveolar walls and capillaries.
The physical act of moving air into and out of the lungs is called:
A. diffusion.
B. ventilation.
C. oxygenation.
D. respiration.
B. ventilation.
Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called:
A. Cheyne-Stokes respirations.
B. ataxic respirations.
C. eupneic respirations.
D. agonal respirations.
A. Cheyne-Stokes respirations.
Which of the following patients is breathing adequately?
A. A conscious female with facial cyanosis and rapid, shallow respirations
B. A conscious male with respirations of 18 breaths/min and reduced tidal volume
C. An unconscious 52-year-old female with snoring respirations and cool, pale skin
D. A conscious male with respirations of 19 breaths/min and pink skin
D. A conscious male with respirations of 19 breaths/min and pink skin
You are ventilating a patient with a stoma; however, air is escaping from the mouth and nose. To prevent this, you should:
A. ventilate with less pressure.
B. seal the mouth and nose.
C. thrust the jaw forward.
D. thoroughly suction the stoma.
B. seal the mouth and nose.
How does CPAP improve oxygenation and ventilation in patients with certain respiratory problems?
A. It forces the alveoli open and pushes oxygen across the alveolar membrane.
B. It decreases intrathoracic pressure, which allows more room for lung expansion.
C. It prevents alveolar collapse by pushing air into the lungs during inhalation.
D. It pushes thick, infected pulmonary secretions into isolated areas of the lung.
A. It forces the alveoli open and pushes oxygen across the alveolar membrane.
Which of the following structures is NOT found in the upper airway?
A. Pharynx
B. Larynx
C. Oropharynx
D. Bronchus
D. Bronchus
