Answer to Question 1
ANS: D
LPNs, or LVNs in California and Texas, are not RNs. They complete an educational program consisting of 12 to 18 months of training, and then they must pass the National Council Licensure Examination for Practical Nurses (NCLEX-PN) to practice as an LPN/LVN. They are under the supervision of an RN in most institutions and are able to collect data but cannot perform an assessment requiring decision making, cannot formulate a nursing diagnosis, and cannot initiate a care plan. They may update care plans and administer medications with the exception of certain IV medications.
Answer to Question 2
ANS: D
Hildegard Peplau focused on the roles played by the nurse and the interpersonal process between a nurse and a patient. The interpersonal process occurs in overlapping phases: (1) orientation, (2) working, consisting of two subphases: identification and exploitation, and (3) resolution. Betty Neuman's Systems Model includes a holistic concept and an open-system approach. The model identifies energy resources that provide for basic survival, with lines of resistance that are activated when a stressor invades the system. Virginia Henderson described the nurse's role as substitutive (doing for the person), supplementary (helping the person), or complementary (working with the person), with the ultimate goal of independence for the patient. Imogene King developed a general systems framework that incorporates three levels of systems: (1) individual or personal, (2) group or interpersonal, and (3) society or social. The theory of goal attainment discusses the importance of interaction, perception, communication, transaction, self, role, stress, growth and development, time, and personal space. In this theory, both the nurse and the patient work together to achieve the goals in the continuous adjustment to stressors.
