Final answer:
The worsening dyspnea on exertion reported by the husband is part of the Subjective section of the SOAP note since it is based on the patient's or family's perspective and not directly measured by the provider.
Step-by-step explanation:
The information provided by the husband that the patient has had worsening dyspnea on exertion would be categorized under the Subjective section of the SOAP note. SOAP stands for Subjective, Objective, Assessment, and Plan. The Subjective component includes all information provided by the patient or family members, describing the patient's condition from their personal perspective, including symptoms and feelings. In this context, the dyspnea on exertion reported is not something that the healthcare provider has observed or measured directly, but rather information conveyed to them, which is why it falls under Subjective.
