Final answer:
The nurse should monitor oxygen saturation after providing initial care for a patient with asthma and impending anaphylaxis hypersensitivity to a drug.
Step-by-step explanation:
The correct step for a nurse to take after providing initial care for a patient with asthma and impending anaphylaxis hypersensitivity to a drug is b. Monitoring oxygen saturation.
Monitoring oxygen saturation is important because it can help the nurse assess the patient's respiratory status and determine if there is a need for further intervention. Anaphylaxis is a severe allergic reaction that can cause a drop in blood pressure, difficulty breathing, and swelling of the airways. Monitoring oxygen saturation can provide valuable information about the patient's oxygen levels and help guide the nurse's actions.
In addition to monitoring oxygen saturation, the nurse should also administer bronchodilators, provide emotional support, and ensure a quiet environment as necessary based on the patient's specific needs and condition.
