Thanks 1. what puts the person with HF at risk for respiratory failure? 2. what are the support interventions for the family of the person on a ventilator? 3. The acronym MONA is commonly used to guide the treatment of chest pain: morphine, oxygen, nitroglycerin and aspirin. Explain how each of these interventions affect chest pain.
