Respiratory Case Study
CONCEPT: OXYGENATION and INFECTION
The story….
C.C is a 82 year old female with a longstanding history of COPD and DM. She
presents to the ED with a 5 day history of worsening dyspnea, productive cough
with moderate amounts of yellow-greenish sputum, fever, chills and malaise. In
addition, she reports increasing nausea and vomiting over the past 3 days. She is
unable to keep food, fluids or her medications down. Due to her limited po intake,
she has discontinued her AM regular insulin.
Questions to ponder/answer…(please try to think about/answer these prior to
moving on in the case study…cover up additional information with a sheet of
paper if your eyes are drawn to the “rest of the story”)

What do you think is going on with this woman?

What information above caused you to sit up and take ‘notice’?

What information/data would you want to gather from her via assessment in
order to safely and effectively care for her?
The story continues….
Vital signs reveal the following:
 T: 38.6,
 P: 120,
 RR: 30,
 BP: 90/58,
 O2 sat: 78 on RA,
 Weight: 100 pounds (decreased 2 pounds from her last visit in the pulmonary
clinic one week ago).
Significant findings on her physical exam include the following:
 General: ill appearing female in acute respiratory distress.
 HEENT: unremarkable.
 CV: Tachycardia, rhythm regular. S1 S2 noted no murmur, no gallop, and no
rub.
 Resp: Crackles 1/3 way up lower lobes, inspiratory and expiratory wheezes
