A patient with chronic obstructive pulmonary disease (COPD) is prescribed oxygen therapy. The nurse understands that oxygen therapy is primarily aimed at: a) Decreasing airway inflammation b) Improving gas exchange and relieving hypoxemia c) Preventing bronchospasm d) Reducing mucus production.

The opening marked by the black arrow connects which of the following: Choose from the following: (A) vestibule to nasal cavity (B) nasopharynx / oropharynx (C) nasal cavity / nasopharynx (D) oropharynx / laryngopharynx (E) nasal cavity / oral cavity

2) when atmosphere pressure is less than alveolar pressure:   A) air moves neither into nor out of the lungs B) atmospheric pressure is never less than alveolar pressure C) inhalation occurs D) exhalation occurs E) the patient dies

Damage to this organ would prevent the pressure differences needed for expiration. a) trachea Ob) mouth c) diaphragm d) alveoli

a build up in fluids in the lung will result in a reduced amount of oxygen in the blood returning to the heart from the lungs because A) the bronchioles have dilated B) there is less hemoglobin in the blood C) the surface area for external respiration has been reduced D) the permeability of the lung capillaries has been increased
