NURS 300 Unit I 2026/2027 – 100+ Nursing Exam Questions & Answers, Nursing Process, Asepsis, Communication, Orem Theory & Genetics – California State University San Marcos (CSUSM)

This NURS 300 Unit I 2026/2027 study guide from California State University San Marcos (CSUSM) is a comprehensive 61-page exam-preparation resource covering foundational nursing concepts through detailed question-and-answer review. The material begins with definitions and the historical development of nursing, Florence Nightingale's contributions, the aims of nursing, Nurse Practice Acts, professional nursing standards, Maslow's Hierarchy of Needs, characteristics of nursing as a profession, current nursing trends, and construction of actual and high-risk nursing diagnoses. A major section covers infection prevention, asepsis, and the chain of infection. Students review reservoirs, portals of exit and entry, modes of transmission, vectors, stages of infection, medical versus surgical asepsis, hand hygiene, infection-related laboratory findings, cleaning, disinfection, sterilization, and CDC standard and transmission-based precautions. The material also addresses aerobic and anaerobic organisms, viruses, fungi, antigens and antibodies, inflammatory responses, systemic manifestations of infection, healthcare-associated infections, C. difficile, MRSA, VISA, VRSA, VRE, and Staphylococcus aureus. The document itself repeatedly references Taylor nursing textbook material, including pages 644, 654–657 and Chapter 27, alongside course presentations on asepsis. The guide provides extensive coverage of therapeutic and professional nursing communication. Topics include David Berlo's communication model, sender-message-channel-receiver processes, denotative and connotative meanings, pacing, intonation, verbal and nonverbal communication, group dynamics, CUS communication, read-back, SBAR, therapeutic helping relationships, and the orientation, working, and termination phases. It further reviews rapport building, listening and conversation skills, interview techniques, assertiveness, barriers to therapeutic communication, and integration of communication throughout the ADPIE nursing process. Additional Unit I content addresses cultural competence, health and illness, health promotion, and the nursing process. Students review ethnicity and race, cultural influences on healthcare, culturally responsive nursing care, dimensions of health, acute versus chronic illness, the Health Belief Model, Health Promotion Model, primary, secondary and tertiary prevention, modifiable and nonmodifiable risk factors, assessment, diagnosis, planning, implementation and evaluation. The guide also explains subjective versus objective data, health histories, physical examination techniques, data clustering and validation, documentation, nursing care plans, measurable expected outcomes, independent nursing interventions, collaborative care, protocols, and standing orders. A particularly detailed section examines Dorothea Orem's Self-Care Deficit Nursing Theory, including self-care agency, therapeutic self-care demand, universal, developmental and health-deviation self-care requisites, methods of helping, and Orem's three nursing systems: wholly compensatory, partially compensatory, and supportive-educative. These concepts are directly applicable to nursing assessment, determining when nursing assistance is required, supporting patient independence, and planning individualized care. The final section focuses on genetics and genomics in nursing practice. It discusses genomic care, nondirective counseling, certified genetic counselors, clinical geneticists, clinical laboratory geneticists, medical and research geneticists, advanced-practice nurses in genetics, genetics clinical nurses, genetic referrals, patient advocacy, confidentiality, and the general nurse's responsibility for recognizing potential genetic concerns. This resource is especially relevant for CSUSM NURS 300 students, California State University San Marcos nursing students, BSN students, introductory and fundamentals of nursing students, pre-licensure nursing students, and learners preparing for Unit I examinations covering nursing foundations, infection control, therapeutic communication, cultural competence, health promotion, ADPIE, nursing diagnosis, Orem's theory, and genetics/genomics.
