Final answer:
The nurse would use a problem-focused approach and a structured comprehensive approach to assess the patient's symptoms of H1N1 flu.
Step-by-step explanation:
Based on the information provided, the nurse's knowledge about the patient, including his age, recent loss, and presenting symptoms of H1N1 flu, would result in a problem-focused approach and a structured comprehensive approach. The nurse would focus on assessing the specific problems related to the patient's respiratory symptoms and H1N1 flu, as well as conducting a comprehensive assessment to gather all necessary information.
Additionally, using multiple visits to gather a complete database may be necessary, as the patient's condition and symptoms may change over time. Finally, focusing on the functional health pattern of the role-relationship would not be a priority in this case, as the patient's symptoms and condition are more directly related to his respiratory health and the flu.
