Guide Questions and Actual Answers
2025\2026 Edition.
Which of the following structures is contained within the mediastinum? - Answer Esophagus
Inhalation occurs when the: - Answer Diaphragm and intercostal muscles contract and cause a
decrease in intrathoracic pressure.
Which of the following factors will cause a decreased minute volume in an adult? - Answer
Shallow breathing
The hypoxic drive is influenced by: - Answer low blood oxygen levels
Which of the following is a late sign of hypoxia? - Answer Cyanosis
A ventilation/perfusion (V/Q ratio) mismatch occurs when: - Answer A disruption in blood flow
inhibits the exchange of oxygen and carbon dioxide in the lungs, even though the alveoli are
filled with fresh oxygen
Which of the following organs or tissues can survive the longest without oxygen? - Answer
Skeletal muscle
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: - Answer remove the airway and be prepared to suction her oropharynx
The physical act of moving air into and out of the lungs is called: - Answer Ventilation
What occurs when a patient is breathing very rapidly and shallowly? - Answer Air moves
primarily in the anatomic dead space and does not participate in pulmonary gas exchange
, Which of the following is the MOST reliable indicator of adequately performed bag-valve mask
ventilations in an apneic adult with a pulse? - Answer Adequate rise of the chest when
squeezing the bag
While providing CPAP to a patient in severe respiratory distress, you note that his heart rate has
increased by 20 beats/min. He is conscious, but is no longer following verbal commands. You
should: - Answer Remove the CPAP device and ventilate him with a bag-valve mask
At a flow rate of 6 L/min, a nasal cannula can deliver an approximate oxygen concentration of
up to: - Answer 44%
Based on the current guidelines, in which of the following situations should you supplemental
oxygen be administered? - Answer Exposure to carbon monoxide and the oxygen saturation of
95%
The term used to describe the amount of gas in air or dissolved in fluid, such as blood. - Answer
partial pressure
Movement of a gas from an area of higher concentration to an area of lower concentration. -
Answer Diffusion
The upper airway consists of: - Answer Nasopharynx, Nasal air passage, Pharynx, Oropharynx,
mouth, Epiglottis, Larynx. It functions to warm, filter and humidify air as it enters the nose and
mouth.
The lower airway consists of: - Answer Trachea and lungs; its function is to exchange oxygen
and carbon dioxide
What procedure requires enhanced PPE? - Answer Aerosol-generating procedures (AGPs)
Diffusion - Answer the process by which molecules move from an area of higher concentration
to an area of lower concentration
How does oxygen reach body tissues and cells? - Answer Breathing and circulation
