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? Copyright © 2013, 2010, 2006, 2002 by Saunders, an imprint of Elsevier Inc.

Patient who is overweight Copyright © 2013, 2010, 2006, 2002 by Saunders, an imprint of Elsevier Inc. 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.
