**Core Concept:** Assessing psychosocial needs of cancer patients is an essential aspect of nursing care, especially in the context of cancer diagnosis and its impact on the patient and their family. This involves identifying emotional and psychological distress, social support systems, and developing a plan to address these needs.

**Why the Correct Answer is Right:** Option D ("Do you feel supported by your family and friends?") is the most appropriate question to elicit information about the patient's psychosocial needs. It addresses emotional support, social support, and overall well-being. A supportive environment contributes to better treatment adherence, coping mechanisms, and overall quality of life for cancer patients.

**Why Each Wrong Option is Incorrect:**

A. ("Have you had any symptoms today?") This question focuses on physical status and does not address the patient's psychosocial needs.

B. ("Do you require any medication changes?") This question is related to medical management and not assessing psychosocial support.

C. ("Tell me about your daily activities.") While this question indirectly touches upon social support, it does not specifically focus on the patient's emotional and psychological well-being, which is crucial in cancer care.

**Clinical Pearl:** Assessing psychosocial needs in cancer patients is a vital part of their holistic care. Nurses should inquire about emotional support, social support, coping mechanisms, and overall well-being to develop an individualized care plan that addresses the patient's unique needs.

**Correct Answer:** Option D ("Do you feel supported by your family and friends?") is the best choice as it focuses on emotional and social support, which are essential components of a patient's psychosocial well-being in the context of cancer diagnosis.
