Answers
Question:
The nurse is caring for a patient with COPD who is on
ventilator therapy. Which test is most beneficial to evaluate
the patient's response to ventilator therapy?
-Spirometry Rationale: Spirometry measures airflow and lung
volumes.
-Pulse oximetry Rationale: Pulse oximetry (SaO2) is a
noninvasive method of measuring oxygen saturation that
helps determine the severity of the respiratory distress.
-Arterial blood gases (ABG) Rationale: ABG measures
oxygenation of the blood, acid-base balance, and the partial
pressure of carbon dioxide, and it identifies the patient's
response to oxygen and ventilation therapy and medications.
-Forced expiratory volume (FEV1) Rationale: FEV1 measures
the amount of air that can be forced out of the lungs after a
full inspiration in one second. "
Answer:
Arterial blood gases (ABG) Rationale: ABG measures

response to oxygen and ventilation therapy and medications.
Test Taking Tips: Look at the stem: "MOST beneficial to
evaluate the response.
Question:
Which is true regarding emphysema?
-It is caused by inflammation of bronchioles. Rationale:
Emphysema causes inflammation of alveoli.
-It is associated with blood-tinged sputum. Rationale: Lung
cancer is associated with blood-tinged sputum.
, -It is associated with chronic respiratory acidosis. Rationale:
Emphysema is associated with chronic respiratory acidosis.
-It is associated with chronic dilation of bronchioles.
Rationale: Chronic dilation is associated with bronchiectasis.
Answer:
-It is associated with chronic respiratory acidosis. Rationale:
Emphysema is associated with chronic respiratory acidosis.
Test Taking Tips: Look for opposites in the answer's choices.
Question:
A patient with chronic obstructive pulmonary disorder
(COPD) is reporting shortness of breath. On assessment, the
nurse finds a pulse rate of 115 beats/min, a blood pressure of
152/94 mm Hg, a temperature of 101°F, and a respiratory rate
of 28. Which respiratory test is priority?
-Perform incentive spirometry Rationale: Spirometry is the
test that measures airflow and lung volumes. This evaluates
the function of the respiratory system. It is not the priority.
-Pulse oximetry Rationale: Pulse oximetry is a noninvasive
method of measuring oxygen saturation. This is important
information to gather.
-Obtain a forced expiratory volume Rationale: Forced
expiratory volume is a major pulmonary function test that
measures the amount of air that can be forced out of the lungs
after a full inspiration. This is not the priority.
-Peak expiratory flow readings Rationale: Peak expiratory
flow readings measure the maximum airflow expired during a
forced expiration. The patient's peak flow readings are
compared with the personal best reading with a reading
obtained during an exacerbation or asthma attack. The
treatment plan is determined based on these readings.
