Final answer:
For an anaphylactic reaction, the nurse should give epinephrine, administer oxygen, and determine the cause.
Explanation:
For a patient presenting with facial swelling, difficulty breathing, and difficulty speaking from an anaphylactic reaction, the nurse should initially:
- Give epinephrine: Epinephrine helps control the immune reaction, constricting blood vessels, relaxing lung muscles, and reducing swelling of airways.
- Administer oxygen: Oxygen can help support breathing and alleviate the respiratory distress.
- Determine the cause: Identifying the allergen triggering the reaction is crucial for appropriate treatment and prevention.
