Description
The purpose of this study was to determine whether a peer nursing student who presents a longitudinal case study on warfarin in a pharmacology course classroom influences prelicensure and postbaccalaureate nursing students' knowledge and perceived knowledge about warfarin. The study was a descriptive design that used a convenience sample of baccalaureate nursing students enrolled in two pharmacology courses. All participating students answered warfarin case-study questions and completed a self-demographic questionnaire, a knowledge pretest and posttest, and a self-efficacy questionnaire after the activity, which evaluated students' knowledge and perceived knowledge on 11 warfarin concepts. For all students (N = 89), the number of correct answers improved significantly between pretests and posttests for Items 2-11 (p < .0001; Wilcoxon signed-rank tests), which evaluated students' knowledge on warfarin's site of action, associated laboratory values, use of vitamin K, and food-drug interactions. However, no significant difference was seen in the number of correct answers for warfarin's mechanism of action. Comparing prelicensure and postbaccalaureate groups by Mann-Whitney tests, no significant difference was seen for pretest total scores (median 7.00, n = 55; median 7.50, n = 34; respectively; p = .399). Similarly, no difference was seen for posttest total scores by groups (prelicensure: median = 9.00, n =54; postbaccalaureate: median = 10.00, n = 32; p = .344). Overall, students in both groups agreed that they could identify and explain all 11 warfarin concepts. The Pearson correlation between the total posttest and total self-efficacy scores for the combined group was .338 (p = .003), demonstrating a low but significant correlation between students' posttest total scores and their perceived warfarin knowledge, as evaluated by the self-efficacy questionnaire.

Description
Information Measurement Theory (IMT) is a concept which was devised for the purpose of understanding how information works in the universe. At its core, it states that 100% of information exists in the universe at any one time, and with enough perception, any event can be predicted based on the initial conditions preceding the event. With this idea in mind, the author of IMT developed the Kashiwagi Solution Model (KSM) which deals with how people best utilize the information present in the universe. Simply put, the ideas presented by KSM encourage people to think in a more logical manner through the utilization of relevant information. The following thesis details an autobiographical case study which focuses on the life of a college student undergoing severe depressive symptoms during the course of their academic career. The usage of concepts stemming from IMT and KSM are then used to determine the root causes of the depression in order to prevent it from ever happening again. The case study acts as a guide to others in order to better help them deal with similar situations that are happening with their lives while providing evidence that the concepts detailed by IMT and KSM are factually relevant.
