Answer to Question 1
ANS: B
Nurses use critical-thinking skills to guide decision making and to solve problems. The scientific method, one approach to problem resolution, is systematic, logical, and based on data collection and hypothesis testing. The steps include (1) identification of the problem, (2) definition or clarification of the problem, (3) statement of the problem, (4) determination of criteria for evaluation, (5) data collection, (6) generation of solutions, and (7) hypothesis testing. Interpretation is used to understand and explain the meaning of data. Analysis includes investigating plans of action on the basis of examination of subjective and objective data is an example of nursing analysis. Evaluation occurs when information, including the reliability, credibility, and bias of the source, is assessed. Nurses also evaluate when determining whether the desired outcome for an intervention was achieved. Recapping the needle is not part of the desired outcome. Inference leads to accurate conclusions that are based on sound reasoning.
Answer to Question 2
ANS: A
During the assessment step, patient care data are gathered through observation, interviews, and physical assessment. During the planning step of the nursing process, the nurse prioritizes the nursing diagnoses and identifies short- and long-term goals that are realistic, measurable, and patient focused, with specific outcome identification for evaluation purposes. The implementation step includes initiating specific nursing interventions and treatments designed to help the patient achieve established goals or outcomes. In the evaluation step, the nurse determines whether the patient's goals are met, examines the effectiveness of interventions, and decides whether the plan of care should be discontinued, continued, or revised.
