Pathophysiology
Part 1: Discussion
Answer the following questions about the respiratory system, using the included case study, for this week’s discussion.
- Explain what ARDS is.
- Explain what is significant with her lab results using the ABG normal values and the nursing mnemonic ROME which was also referenced in week #2 of this course.
- Explain what an appropriate treatment would be.
- At least 200 – 250 words
Case Study:
Mrs. Breathless is a 43-year-old female, just getting off the late shift. She reports to the ER in the early morning with shortness of breath. She has cyanosis of the lips. She has had a productive cough for 2 weeks. Her temperature is 102.2, blood pressure 110/76, heart rate 108, respiration 32, rapid and shallow. Breath sounds are diminished in both bases, with coarse rhonchi in the upper lobes. Chest X-ray indicates bilateral pneumonia.
- ABG (Arterial Blood Gases) Lab results are:
- pH= 7.44
- PaCO2= 28
- HCO3= low
- PaO2= 54
Note: rhonchi are continuous low pitched rattling lung sounds that often resemble snoring or wheezes.
Problems:
- PaCO2 is low.
- pH is on the high side of normal, therefore compensated respiratory alkalosis.
- Also, PaO2 is low, probably due to mucous displacing air in the alveoli affected by the pneumonia.
Part 2:
This week, you will have the opportunity to unleash your creativity in order to help you and your classmates study.
