Which term predicts the outcome on a client's health, such as improved health or recovery from illness?

• A. Theory
• B. Hypothesis
• C. Evidence Based Practice
• D. Model

Answer: (B)

Predicting how a client's health will change from a specific action relies on a statement that can be tested with data. That statement is a hypothesis. It specifies a clear relationship between an intervention (the independent variable) and an outcome (the dependent variable) in a defined population, and it’s designed to be tested and potentially falsified through observation or experiments. For example, “If a client receives this nursing intervention, then their health status will improve within X days.” A theory, in contrast, is a broad, well-supported explanation that helps us understand why such relationships occur across many settings, not a single, testable prediction about one outcome. A model is a simplified representation used to illustrate relationships or processes, which can aid understanding but isn’t itself a tested prediction about an outcome. Evidence Based Practice refers to using the best available evidence, clinical expertise, and patient preferences to guide care—not a specific forecast about an individual patient’s result.
