Registered Practical Nurse (RPN) Practice Test

Which domain is included in the Nursing Interventions Classification (NIC) system?

1. Safety

2. Cost reduction

3. Psychosocial support

4. Clinical trials

The correct answer is: Safety

The Nursing Interventions Classification (NIC) system is designed to provide a standardized classification of nursing interventions. It organizes nursing activities into different domains that reflect the various aspects of patient care. One of the critical domains included in this classification is safety. This domain encompasses interventions aimed at ensuring patient safety, preventing harm, and managing risks associated with health care. Safety as a domain includes actions taken by nurses to create a secure environment, monitor for potential threats to patient welfare, and implement strategies to protect patients from injury or complications during their care. This focus is central to nursing practice, as patient safety is a primary concern in health care settings. While cost reduction, psychosocial support, and clinical trials may involve nursing interventions, they do not represent distinct domains within the NIC system. Cost reduction relates more to healthcare economics than direct intervention classification. Psychosocial support is indeed relevant to nursing practice but is considered a specific type of intervention rather than a broad domain. Clinical trials pertain to research methodology rather than direct patient care interventions in the NIC. Therefore, safety is the domain that directly aligns with the NIC's framework.
