The patient is a 55-year-old woman with a long
history of COPD and 40 years of smoking
cigarettes. She is being admitted to the pulmonary
stepdown unit from the ED. The ED nurse tells
you that the patient is on oxygen at 2 L per nasal
cannula. She had a bronchodilator respiratory
treatment in the ED as well. She has bilateral
expiratory wheezes and crackles both anteriorly
and posteriorly. A saline lock was placed in her
right forearm for intermittent medications.
Copyright © 2013, 2010, 2006, 2002 by Saunders, an imprint of Elsevier Inc.
Based on the patient’s diagnosis, which clinical
manifestations would you expect to see when assessing
this patient? (Select all that apply.)
A. Funnel chest appearance
B. Sitting in a forward posture
C. Shortness of breath
D. Bradycardia
E. Use of accessory muscles
Copyright © 2013, 2010, 2006, 2002 by Saunders, an imprint of Elsevier Inc.
When the patient arrives to the unit, you
complete her assessment and find her to be in
acute respiratory distress. Her respirations are
labored and her respiratory rate is 34. She states
that she is severely short of breath. Her oxygen
saturation is 82% on O2 at 2 L via nasal cannula.
Based on these findings, what should you do
next?
Copyright © 2013, 2010, 2006, 2002 by Saunders, an imprint of Elsevier Inc.
While the Rapid Response Team is at the bedside, the
patient’s health care provider arrives. The provider
writes several orders.
Which order is most important for you to implement
immediately?
A. Transfer to ICU
B. Increase O2 to 3 L per nasal cannula
C. ABGs 30 min after oxygen is increased
D. Methylprednisolone sodium succinate (Solu-Medrol)
40 mg IVP
Copyright © 2013, 2010, 2006, 2002 by Saunders, an imprint of Elsevier Inc.
The patient is in the ICU for 3 days and then transferred
back to the pulmonary stepdown unit. She is still
slightly short of breath with exertion. Her O2 saturation
is 99% on oxygen at 2 L per nasal cannula. She denies
any shortness of breath during your assessment. The
provider plans to discharge the patient on home oxygen
in the morning.
What should you include in this patient’s discharge
teaching?

B. Occupational radiation exposure
C. Chronic exposure to asbestos
D. Air pollution

failure
D. Patient who is overweight

A patient with a history of asthma is having shortness of
breath. The nurse discovers that the peak flowmeter
indicates a peak expiratory flow (PEF) reading that is in
the red zone. The nurse should immediately:
A.
B.
C.
D.
Repeat the PEF reading to verify the results.
Take the patient’s vital signs.
Administer the rescue drugs.
Notify the patient’s prescriber.
