I always have trouble with prioritizing my nursing diagnosis. For my Sim lab, my patient was diagnosed with acute asthma exacerbation. She was coughing up thick, yellow sputum. Her O2 sats started at 92% and dropped to 89%. She had a temp. of 100.9, BP was 148/88, RR was 38, P was 130. She was on 4L/m O2 with a progressive upward titration to maintain adequate saturation. The provider supected that she also had a respiratory infection. She was very anxious. I used the nursing dx of 1. Ineffective airway clearance, 2. Ineffective breathing pattern and 3. Anxiety. Can anyone help with the rationale of prioritizing? I would appreciate the help.
