RECALLS 12 NURSING PRACTICE 4 Situation: As a nurse researcher in the research and development center of her hospital, Nurse Rianna is assigned to conduct a research study on the levels of competence of the hospital’s staff nurses. She is given 12 months for the study’s duration. 1. Nurse Rianna is composing her proposal, which design will she use if Rianna wants to assess the competence of the staff nurses upon appointment to the job until their respective retirements? A. Retrospective B. Cross-sectional C. Longitudinal D. Descriptive-correlational Answer is C. Longitudinal – assessment of data is collected over an extended period from appointment until retirement. 2. During the project planning, Rianna realizes that she cannot use randomization for her subjects due to the nature of the work setting. Considering this, what research design should Rianna employ when randomization is not permitted? A. Experimental B. Quasi-experimental C. Prescriptive D. Correlational Answer is B. Quasi-experimental as this design lack randomization to treatment groups. 3. As part of her research, Nurse Rianna plans to implement a new competency-based training design in which she will later evaluate the competency levels of the nurses who underwent and did not participate in the new program. What research design is applicable for Rianna to employ? A. Cross-sectional B. Experimental C. Retrospective D. Descriptive Answer is B. Experimental – there is manipulation in the study, the researcher implements a competency-based training design to the subjects to evaluate their competency levels. The researcher does not aim to describe a phenomena, look for a cause, and it is not stated if data is collected at one point in time. 4. Rianna formulated the hypothesis of her research, which pertains to a simple hypothesis? A. The level of competence is the same for those with clear perception and those who have unclear role perception B. Role perception increase the level of competence among staff nurses C. Level competence is influenced by role perception D. Role perception is not related with the level of competence among staff Answer is B. which has 1 independent variable (role perception) and 1 dependent variable (level of competence). We define a simple hypothesis as a hypothesis that expresses an expected relationship between one independent and one dependent variable. A complex hypothesis is a prediction of a relationship between two (or more) independent variables and/or two (or more) dependent variables. Complex hypotheses sometimes are referred to as multivariate hypotheses because they involve multiple variables. 5. When a competency-based training program for the staff nurses is introduced by Nurse Rianna, which element of experimental research would this action refer to? A. Evaluation B. Manipulation C. Control D. Randomization Answer is B. Manipulation – the experimenter does something (introduction of competency-based training program) for the staff nurses.
