Choice A rationale:

When assessing a patient with lymphoma, it is crucial to gather information about the characteristics of their symptoms.

Lymphoma symptoms can vary widely depending on the type, stage, and location of the cancer.

Understanding the specific symptoms, such as fatigue, night sweats, enlarged lymph nodes, unexplained weight loss, and itching, can help the nurse assess the severity and progression of the disease.

This information guides the healthcare team in making a diagnosis, determining the appropriate treatment plan, and monitoring the patient's response to treatment.

Choice B rationale:

"Do you have a family history of cardiovascular disease?" While family history is important for assessing the risk of various health conditions, including cardiovascular disease, it is not the primary concern when assessing a patient with lymphoma.

Lymphoma is a type of cancer, and the focus should be on gathering information related to cancer symptoms and risk factors.

Choice C rationale:

"Have you ever had surgery?" The patient's surgical history may be relevant for their overall health assessment, but it is not the top priority when assessing a patient with lymphoma.

The nurse should first focus on collecting information directly related to lymphoma symptoms, diagnosis, and treatment.

Choice D rationale:

"What is your favorite type of food?" The patient's food preferences are not relevant to the assessment of lymphoma.

This question does not provide essential information for evaluating the patient's condition or developing an appropriate care plan.
