In the National Council Licensure Examination for Registered Nurses (NCLEX-RN) examination test plan, client needs form the organizing framework of the examination with questions in four categories: safe and effective care environment, health promotion and maintenance, psychosocial integrity, and physiologic integrity. Certain processes are then integrated throughout the categories of client needs. Which process is integrated into all client need categories?

1. Infection control is crucial in ensuring safe and effective care for all clients.
2. Infection control measures are essential in preventing the spread of infections in healthcare settings.
3. Infection control is relevant in promoting and maintaining health by preventing illness.
4. Psychosocial integrity can be compromised by infections, making infection control important in this category.
5. Physiologic integrity involves preventing and managing infections through proper protocols.
6. While teaching/learning, health promotion, and pharmacology are important, they are not integrated into all client need categories like infection control.
