Nursing Diagnoses

I am having a little trouble with nursing diagnoses. I was just looking for a little guidance and wanted to check if I was on the right track.

My Diagnosis is:

Impaired gas exchange secondary to anemia as evidenced by shortness of breath with any exertion.

HGB is 9mg/dL

I need an assess, do, teach.

I was thinking my interventions would be respiratory monitoring and oxygen therapy.

Assess:

I would assess the lungs for areas of decreased ventilation and the presence of adventitious sounds.

DO: Position patient with proper body alignment

Teach: appropriate breathing and coughing techniques

Assess:

I would monitor for changes in BP and HR

Do: change patient's position every 2 hours

Teach: Explain the need to restrict and pace activities to decrease oxygen consumption during an acute episode.

Or should I assess Oxygen therapy? use a pulse ox to monitor for oxygen saturation

Do:

Teach: Home health services for nursing care or oxygen management.

I'm completely lost with this. If anyone has any advice or any kind of direction I would appreciate it. Thanks in advance.
