pulmonary hyperinflation, a widened
anteroposterior diameter, an increased depth of the

infiltrate consistent with
pneumonia.
ARTERIAL BLOOD GASES; PaO2 52mm Hg; PaCO2 68 mm Hg
DIAGNOSIS: COPD
Short answer critical thinking:
#1- What tests were performed to determine the patient’s
diagnosis ?
#2- Which component (disease process) of COPD is causing
alveolar distention and loss of elasticity in the lung tissue?
#3- The patient was diagnosed with COPD. Which DX included
in the case study would be a secondary condition in need of
treatment? Name one possible treatment for this
condition.
#4- What subjective and objective information relates to the
bronchitis component of the COPD?
#5- The definition of retrosternal air space is:
