I need some help with the following case scenario:

Mrs. J. is a 63-year-old woman who has a history of hypertension, chronic heart failure, and sleep apnea. She has been smoking two packs of cigarettes a day for 40 years and has refused to quit. Three days ago, she had an onset of flu with fever, pharyngitis, and malaise. She has not taken her antihypertensive medications or her medications to control her heart failure for 4 days. Today, she has been admitted to the hospital ICU with acute decompensated heart failure.

Subjective Data:

- Is very anxious and asks whether she is going to die.

- Denies pain but says she feels like she cannot get enough air.
