A theory is a set of concepts, definitions, relationships and assumptions that:

Correct Answer: A

Rationale: A theory in nursing, like Orem's Self-Care Deficit, comprises concepts (e.g., self-care), definitions (clarifying terms), relationships (how concepts interact), and assumptions (underlying beliefs), all to explain phenomena patterns or events like patient recovery. This explanatory role guides practice by providing a lens to understand health-related behaviors or outcomes. Formulating legislation is unrelated; theories inform policy indirectly but aren't legal tools. Measuring nursing functions might be a research outcome, not a theory's purpose, which is broader and conceptual. Reflecting the domain of nursing practice describes what theories encompass but not their active function explanation drives their utility. By explaining phenomena, theories offer nurses frameworks to predict, interpret, and address patient needs, making this the most accurate description of a theory's role in nursing science.

Correct Answer: A

Rationale: Anticipatory grieving mourning before a loss (e.g., terminal diagnosis) helps clients or families process emotions gradually, fostering a healthier emotional state. It allows acceptance over time, reducing shock post-loss (e.g., preparing for a loved one's death). Privacy is possible but not the benefit grieving's value lies in emotional work, not seclusion. Drawing family closer may occur, but it's secondary; individual coping is primary. Discussing with others aids support, not the core benefit. By facilitating emotional adjustment e.g., a patient accepting mortality anticipatory grieving eases transition, a key nursing focus in end-of-life care, making this the primary advantage.
