Listening And Critical Thinking Pdf Nursing

INTRODUCTION

Critical thinking (CT) is an essential component in the nursing and problem-solving process that should be oriented by standards, policies and codes of ethics. It also involves logic, intuition and creativity, which are equally essential and become stronger with specific knowledge and clinical experience. CT targets safety and quality by focusing on needs of patients, families and the community (1).

Critical thinking is described as an essential elements in the professional practice routine, considering the complexity of healthcare and expressive technical and scientific advancements in the last century that demand the development of cognitive analysis, interpretation and inference skills that help nurses make safe decisions(2-3).

In the 20th century, when the Nursing Process (NP) was incorporated in nursing knowledge, intelligence was identified as an important dimension in the nursing practice, especially in the 1980s when studies on Nursing Diagnosis (ND) and diagnostic accuracy were conducted, both of which supported the development of clinical reasoning (3).

Although this topic has been gaining the spotlight and academic significance since the 1990s, which is the result of studies in different contexts of nursing, critical thinking was born with Modern Nursing founded by Florence Nightingale in the 19th century. The care that was provided, planned and implemented by Florence Nightingale was founded on technical and scientific knowledge, clinical experience and inter-personal skills that helped her make assertive decisions in relation to patients (1,3).

In light of continuous and complex modifications in the healthcare context, critical thinking of nurses allows the provision of safe care insofar as the clinical practice is based on cognitive and logical processes that grant competency and skills to precisely diagnose patients' health problems (4).

The dimensions of critical thinking comprise elements that configure cognitive skills and habits of mind. In addition to these dimensions, behavioural or emotional skills based on attitudes of conscious social and humanist efforts or involvement of the critical thinker with the individual and situation that is under evaluation should also be observed.

These cognitive skills include analysis, application of standards, discernment, search for information, logical reasoning, prevision and transformation of knowledge. Habits of mind are structured around trust, contextual perspective, creativity, flexibility, inquisition, intellectual integrity, intuition, understanding, perseverance and reflection(5). The structural elements were identified in a study that evaluated the opinion of specialist nurses on nursing (6), and concluded that the manifestation of mental habits is evident among nurses that reason in a critical manner, which favours the decision-making process. Clinical decision making as a complex activity that requires both the experience of nurses on priorities when organizing the care environment and use of available information to enable the provision of care (5).

Consequently, CT is defined as a basic competency of nurses to organize the nursing process and solve the problems of patients (2), thus enabling the safe and effective provision of care in different clinical environments (5,7). Given the nature of care in emergency services, decision making must be precise, considering it is a systemic evaluation and judgement process that comprises cognitive and behavioural skills that are inherent to critical thinking (4,8-9).

Based on the premise that structural elements of CT permeate the clinical practice of nurses, expanded and in-depth studies on analysing these elements is therefore justified, within the context of emergency services, to support strategies that enhance this skill in the diagnostic process. It was therefore important to determine which elements of critical thinking are used by nurses during clinical decision making in emergency services. For this reason, the purpose of this study was to analyse the elements that structure critical thinking during the decision-making process of nurses in emergency units of general public hospitals.

METHOD

The presented data was obtained from explanatory, qualitative research conducted at the emergency units of three general and public hospitals in the municipality of Porto Alegre, Rio Grande do Sul, Brazil.

Study participants were 20 nurses selected according to convenience, of which 12 worked in the general hospital's emergency unit, six in the emergency service of a benchmark trauma hospital and two in emergency rooms of a maternity and children's hospital. Criterion for inclusion was: practicing nurse with at least one year of experience in the study field. Nurses that conducted management or administrative roles and who were hired for a probationary period were excluded from the study.

Data were collected from April to June 2009 by means of a questionnaire that was completed by the participants. The first item of the questionnaire included identification, sex, age, academic background, professional background, graduate studies and attendance to permanent education course. The second item presented a problem-situation portrayed as a validated clinical case study (10). The case study was about an elderly man with a medical diagnosis of congestive heart failure who sought assistance due to chest pain and shortness of breath, and other relevant signs and symptoms.

Based on this clinical case, nurses had to list the patient's health problems, prescribe nursing care and mention the expected results. After this stage, participants had to list, by order of priority and within a pre-established framework, the first five structural elements of CT they had used to solve the clinical case(5). The presented structural elements included experience, ethics, technical and scientific knowledge, patient knowledge, patient assessment, logic, teamwork/human resources, material resources, patient assessment instrument and intuition. Then nurses were asked to define the elements they selected.

Obtained data were analysed using the content analysis method(11) that comprises three distinct stages: pre-analysis, exploration of material and treatment of results and interpretation.

The first stage consisted of organizing definitions of CT elements used by the nurses, which are configured in record units. The second stage consisted of creating categories based on similarity of content and the framework adopted in this study(3-5). The CT elements prioritized by the nurses were associated to these categories. Treatment of these results and interpretation, which is the third stage of content analysis, was conducted using the adopted theoretical framework.

This study complied with the principles of Resolution 196/96 of the National Health Council(12), and was approved by the Research Ethics Committee, registered under number 253/08. All subjects who participated in this study signed an Informed Consent agreement and were identified using numbers to protect their identities.

RESULT AND DISCUSSION

Collected data allowed the characterization of participating nurses in relation to sex, age, and academic and professional background in the study field. Most of the subject were women (18), with an average age of 32.5 ± 7.5 years. In relation to background, 15 nurses had an academic background of at least eight years and a median of two to six years of experience in the study field.

The characterization of complementary education of nurses showed that 18 had graduate studies in different nursing practice fields and two nurses had master's-level studies. In relation to permanent institutional education courses, those on the Systematization of Nursing Care (SAE) and adult patient care were the most common, attended by eight and four nurses, respectively. Of all the participants, eight nurses had not attended any such courses.

STRUCTURAL ELEMENTS OF CRITICAL THINKING OF NURSES IN EMERGENCY UNITS

Content analysis revealed three categories that were related to structural elements of CT listed by the nurses: associating theoretical and practical bases for clinical decision making:technical and scientific knowledge and clinical experience; thought process and clinical decision making:clinical reasoning, clinical judgement, intuition, prediction; basis for nurses' clinical judgement:patient assessment, ethics, knowledge of the patient, cultural knowledge, application of normality and ethical standards. These categories and the respective structural CT elements are discussed below, based on the theoretical framework adopted in this study.

Associating theoretical and practical bases for clinical decision making

Clinical experience and technical and scientific knowledge are essential components and complements to define patient care actions. Clinical experience was defined by nurses as:

[...] associating signs and symptoms to previous diseases. (Nurse 1)

Associating theory and practice. (Nurse 5)

Experience with emergency patients with the mentioned characteristics [...]. (Nurse 9)

Similar situations that occur in all my shifts during my work routine help me recognize the different pathologies. (Nurse 11)

Capacity constructed in time, through daily experiences with patients, to reach excellence in nursing care. (Nurse 18)

Associated to clinical experience, technical and scientific knowledge was defined as being the basis to implement actions, as suggested by other nurses.

Always seek to develop this stage and support our practices. Study groups. (Nurse 4)

[...] literature was used to establish this model (care). (Nurse 7)

Needed to adapt care to the presented signs and symptoms. (Nurse 11)

Helps to plan nursing practices. (Nurse 12)

Physiopathology helps clinical reasoning, decision making. (Nurse 6)

[...] based on theoretical knowledge/pathologies. (Nurse 14)

Knowledge and function of physiological standards can be used to build a model based on experiences with patients. (Nurse 18)

Evaluation of the clinical case study provided to the nurses revealed that priorities of clinical decision making are technical and scientific knowledge and clinical experience as elements of CT. The association that participants of this study made between signs and symptoms of diseases and cases of their clinical practice or previous experience with patients that have similar symptoms showed the development of critical thinking for clinical decision making.

From the viewpoint of nurses, clinical experience has a direct relationship with daily work experiences in the emergency units, and helped these professionals to recognize clinical situations and identify the specific care needs of patients.

Similar results were obtained in a study conducted with clinical practice nurses showing that experience and academic background of these professionals was essential to increase critical thinking skills (2).

In the context of professional background, clinical experience was pinpointed and defined by scholars as being an important competency for the development of critical thinking, resulting from knowledge acquired by nurses and their experiences in specific situations of their daily care routine(13-14).

Thought process and clinical decision making

Analysis and interpretation of the case study allowed nurses from this study to identify and define structural elements that, according to their evaluation, constituted critical thinking and led to clinical decision making: clinical reasoning and clinical judgement, intuition and prediction.

Clinical reasoning and clinical judgement are different, albeit complementary, aspects in the exercise of nurses' evaluations, being that the former leads to judgement, or decision making (13). From these structural CT elements in this category emerged the inter-relation of these elements in the clinical reasoning process expressed in the following statements.

It is thought directed to a problem-situation with the purpose of making the best decision. (Nurse 11)

Clinical history + signs and symptoms + physical exams are part of the assessment process and allow the identification of problems (literal transcription of a participant's statement). (Nurse 14)

The interview, the physical exam, symptoms of the disease are relevant factors that lead to the set of decisions that have to be made in the diagnostic process, which requires clinical reasoning. (Nurse 18)

As a complement to the definitions above, nurse 13 emphasized clinical reasoning and its importance in the context of care.

Necessary to evaluate patients in the short, medium and long term in relation to measures, urgent care, care plans, nursing prescriptions and expected results. (Nurse 13)

Of the critical thinking elements, intuition was described by only one nurse, as follows:

Knowing how to identify possible complications by observing the patient, who directs you to possible problems or situations. (Nurse 11)

Intuition, one of the mental habits of critical thinkers, is defined as the perceptive sensation of knowing without conscious use of reason; immediate knowledge that is not dependant on reasoning(7,15). Intuition, associated to cognitive CT skills, guides nurses when making precise clinical decisions.

Basis for nurses' clinical judgement

The clinical judgement of nurses was based on the following structural CT elements: patient evaluation, ethics, knowledge of patient, cultural knowledge, application of normality standards.

Technological advancements in healthcare have contributed to the quality of diagnostic and therapeutic processes. However, during patient evaluation, anamnesis and physical examinations are basic instruments of the nursing process(13-14).

Consequently, participants of this study stated anamnesis, physical examination and the application of normality standards as being the structural elements of critical thinking that support the clinical judgement of nurses.

Surveying of information and patient reception. (Nurse 2)

Important for the construction of anamnesis that will support interventions. I am referring to information such as: Does not take medication, does not follow diet. (Nurse 6)

Helps to plan nursing actions. (Nurse 12)

Anamnesis and physical examinations guide nurses when planning care. (Nurse 13)

Crown-rump evaluation. Observe patients as a whole. (Nurse 15)

Knowing signs and symptoms of the disease through patient evaluations is an important element that guides the prescription of nursing care. (Nurse 18)

To adapt care according to the presented signs and symptoms. (Nurse 19)

Inter-personal, technical and intellectual skills(4) for conducting clinical examinations are essential elements in clinical practice. When evaluating patients, nurses must consider and respect the knowledge and culture of patients, and know how to listen to them(14), which helps to recognize signs and symptoms and their motives for seeking healthcare services.

In nursing care practices, the ability to listen to others is fundamental because it helps to determine the best way to communicate with patients according to their cultural level and knowledge of their health status(14), which was emphasized in the following statements:

Adapt what we say and our actions to their reality and their cultural level. (Nurse 1)

Listening to patients; Identify the difficulties. (Nurse 2)

Professional practices should be ethical. (Nurse 13)

Clinical judgement was listed and defined by 10 of the 20 nurses in this study, who associated it to adequate investigation of data on clinical histories, the conduction of physical examinations and recognition of signs and symptoms related to the patient's problem. In nursing care, data collection is the first stage of the nursing process (1). The scientific interpretation of these data refers to the identification of nursing diagnoses, which are established in the nurse's clinical judgement and guide the remaining stages of the nursing process(4).

During data analysis, it was perceived that subjects with master's degrees were more familiar with the structural elements of clinical thinking than the others, which is evident in the statement of Nurse 11, and corroborated in a study (2).

Based on the patient's history and evaluation, judgements are made to appropriately plan care. (Nurse 11)

It should be noted that reasoning and clinical judgement, albeit conceptually different, involve cognitive and reflexive mental processes that are associated to previous clinical experiences, which are associated to technical and scientific knowledge that supports this thinking process (13).

Clinical judgements is structured according to the following skills: interpersonal, which involves the ability to communicate, listen and respect opinions; technical, including solid knowledge on clinical evaluation methods and scientific knowledge on health problems; intellectual, which refers to thought processes and the perception skills of nurses in relation to human responses (4,15). The association of these skills helps nurses to make safe decisions and provide qualified care according to the real needs of patients.

Although verbal communication between nurses and patients in emergency environments can be impaired due to the clinical conditions of patients and characteristics of this sector, this process is fundamental when collecting data that will lead to the identification of needs, clinical judgements and the precise planning of care.

Furthermore, the structural elements of critical thinking can also be present in all daily decision making of professional practices that are not directly involved in patient care, but are related to a multi-disciplinary team and management aspects that permeate the organization of complex services such as emergency care.

FINAL CONSIDERATIONS

The analysis of structural elements of critical thinking defined by nurses of emergency services, in this study, showed that technical and scientific knowledge, patient evaluation, clinical experience, clinical reasoning and ethics were considered priorities by study participants during clinical decision making.

Critical thought is a skill that nurses need in order to improve clinical reasoning and subsequently implement a precise and safe care process.

Study limitations were the need to validate elements that structure CT and their definitions by the nurses that participated in this research. This condition supports the need for future studies on this topic.

Results helped to reveal the importance of critical thinking for clinical decision making. The growing complexity of health care in the nurses' practice scenarios demands that nurses use the different dimensions of critical thinking and behavioural and affective skills in the nursing diagnostic process. This is a fundamental presupposition for education, research and care that targets the formation of thinkers with the necessary skills to practice a humanistic profession.

To become a professional nurse requires that you learn to think like a nurse. What makes the thinking of a nurse different from a doctor, a dentist or an engineer?  It is how we view the client and the type of problems we deal with in practice when we engage in client care. To think like a nurse requires that we learn the content of nursing; the ideas, concepts and theories of nursing and develop our intellectual capacities and skills so that we become disciplined, self-directed, critical thinkers.


Critical thinking is the disciplined, intellectual process of applying skilful reasoning as a guide to belief or action (Paul, Ennis & Norris). In nursing, critical thinking for clinical decision-making is the ability to think in a systematic and logical manner with openness to question and reflect on the reasoning process used to ensure safe nursing practice and quality care (Heaslip). Critical thinking when developed in the practitioner includes adherence to intellectual standards, proficiency in using reasoning, a commitment to develop and maintain intellectual traits of the mind and habits of thought and the competent use of thinking skills and abilities for sound clinical judgments and safe decision-making.

Intellectual Standards for Reasoning

Practitioners in nursing who are critical thinkers value and adhere to intellectual standards. Critical thinkers strive to be clear, accurate, precise, logical complete, significant and fair when they listen, speak, read and write. Critical thinkers think deeply and broadly. Their thinking is adequate for their intended purpose (Paul, Scriven, Norris & Ennis). All thinking can be examined in light of these standards and as we reflect on the quality of our thinking we begin to recognize when we are being unclear, imprecise, vague or inaccurate. As nurses, we want to eliminate irrelevant, inconsistent and illogical thoughts as we reason about client care. Nurses use language to clearly communicate in-depth information that is significant to nursing care. Nurses are not focused on the trivial or irrelevant.

Nurses who are critical thinkers hold all their views and reasoning to these standards as well as, the claims of others such that the quality of nurse's thinking improves over time thus eliminating confusion and ambiguity in the presentation and understanding of thoughts and ideas.


Elements of Reasoned Thinking

Reasoning in nursing involves eight elements of thought. Critical thinking involves trying to figure out something; a problem, an issue, the views of another person, a theory or an idea. To figure things out we need to enter into the thinking of the other person and then to comprehend as best we can the structure of their thinking. This also applies to our own thinking as well. When I read an author I'm trying to figure out what the author is saying; what problem or issue the author is addressing, what point of view or frame of reference he is coming from, what the goal or purpose is of this piece of writing, what evidence, data or facts are being used and what theories, concepts, principles or ideas are involved. I want to understand the interpretations and claims the author is making and the assumptions that underlie his thinking. I need to be able to follow the author's lines of formulated thought and the inferences which lead to a particular conclusion. I need to understand the implications and consequences of the author's thinking. As I come to understand the author in-depth I will also begin to recognize the strength and weakness of his reasoning. I will be able to offer my perspective on the subject at hand with a clear understanding of how the author would respond to my ideas on the subject.


The Elements of Thought

All thinking, if it is purposeful, includes the following elements of thought (Paul, 1990).

  1. The problem, question, concern or issue being discussed or thought about by the thinker. What the thinker is attempting to figure out.
  2. The purpose or goal of the thinking. Why we are attempting to figure something out and to what end. What do we hope to accomplish.
  3. The frame of reference, points of view or even world view that we hold about the issue or problem.
  4. The assumptions that we hold to be true about the issue upon which we base our claims or beliefs.
  5. The central concepts, ideas, principles and theories that we use in reasoning about the problem.
  6. The evidence, data or information provided to support the claims we make about the issue or problem.
  7. The interpretations, inferences, reasoning, and lines of formulated thought that lead to our conclusions.
  8. The implications and consequences that follow from the positions we hold on the issue or problem.

When nurses reason they use these elements of thought to figure out difficult questions and recognize that their thinking could be flawed or limited by lack of in-depth understanding of the problem at issue therefore, they critically monitor their thinking to ensure that their thinking meets the standards for intellectual thought.

In summary, as a critical thinker, I am able to figure out by reading or listening critically what nurse scholars believe about nursing and on what basis nurses act as they practice nursing. To do this I must clearly comprehend the thinking of another person by figuring out the logic of their thinking. I must comprehend clearly the thinking of myself by figuring out my own thoughts on the subject at hand. Finally, I must use intellectual standards to evaluate my thinking and the thinking of others on a given problem such that I can come to a defensible, well reasoned view of the problem and therefore, know what to believe or do in a given circumstance. To do this I must be committed to developing my mind as a self-directed, independent critical thinker. I must value above all else the intellectual traits and habits of thought that critical thinkers possess.

Intellectual Traits and Habits of Thought

To develop as a critical thinker one must be motivated to develop the attitudes and dispositions of a fair-minded thinker. That is, one must be willing to suspend judgments until one truly understands another point of view and can articulate the position that another person holds on an issue. Nurses come to reasoned judgments so that they can act competently in practice. They continually monitor their thinking; questioning and reflecting on the quality of thinking occurring in how they reason about nursing practice. Sloppy, superficial thinking leads to poor practice.

Critical inquiry is an important quality for safe practice. Nurses must pose questions about practice and be willing to attempt to seek answers about practice. Nurses must be willing to attempt to seek answers to the difficult questions inherent in practice, as well as the obvious. Question posing presupposes intellectual humility and a willingness to admit to one's areas of ignorance as well as, intellectual curiosity and perseverance and willingness to seek answers. Critical thinkers in nursing are truth seekers and demonstrate open-mindedness and tolerance for others' views with constant sensitivity to the possibility of their own bias.

Nurse's who are critical thinkers value intellectually challenging situations and are self-confident in their well reasoned thoughts. To reason effectively, nurses have developed skills and abilities essential for sound reasoning.


Critical Thinking Skills and Abilities

Critical thinkers in nursing are skilful in applying intellectual skills for sound reasoning. These skills have been defined as information gathering, focusing, remembering, organizing, analyzing, generating, integrating and evaluating (Registered Nurse's Association of British Columbia, 1990). The focus of classroom and clinical activities is to develop the nurse's understanding of scholarly, academic work through the effective use of intellectual abilities and skills. As you encounter increasingly more complex practice situations you will be required to think through and reason about nursing in greater depth and draw on deeper, more sophisticated comprehension of what it means to be a nurse in clinical practice. Nursing is never a superficial, meaningless activity. All acts in nursing are deeply significant and require of the nurse a mind fully engaged in the practice of nursing. This is the challenge of nursing; critical, reflective practice based on the sound reasoning of intelligent minds committed to safe, effective client care.


To accomplish this goal, students will be required to reason about nursing by reading, writing, listening and speaking critically. By doing so you will be thinking critically about nursing and ensuring that you gain in-depth knowledge about nursing as a practice profession.

Critical Thinking...a Holistic Approach

Critical Listening: A mode of monitoring how we are listening so as to maximize our accurate understanding of what another person is saying. By understanding the logic of human communication - that everything spoken expresses point of view, uses some ideas and not others, has implications, etc., critical thinkers can listen so as to enter empathetically and analytically into the perspective of others.

Critical Thinking: 1) Disciplined, self-directed thinking which implies the perfection of thinking appropriate to a particular mode or domain of thinking. 2) Thinking that displays master of intellectual skills and abilities. 3) The art of thinking about your thinking while you are thinking in order to make your thinking better: more clear, more accurate, or more defensible.

Critical Writing: To express oneself in languages required that one arrange ideas in some relationships to each other. When accuracy and truth are at issue, then we must understand what our thesis is, how we can support it, how we can elaborate it to make it intelligible to others, what objections can be raised to it from other points of view, what the limitations are to our point of view, and so forth. Disciplined writing requires disciplined thinking; disciplined thinking is achieved through disciplined writing.


Critical Reading: Critical reading is an active, intellectually engaged process in which the reader participates in an inner dialogue with the writer. Most people read uncritically and so miss some part of what is expressed while distorting other parts. A critical reader realizes the way in which reading, by its very nature, means entering into a point of view other than our own, the point of view of the writer. A critical reader actively looks for assumptions, key concepts and ideas, reasons and justifications, supporting examples, parallel experiences, implications and consequences, and any other structural features of the written text to interpret and assess it accurately and fairly. ( Paul, 1990, pp 554 & 545 )

Critical Speaking: Critical speaking is an active process of expressing verbally a point of view, ideas and thoughts such that others attain an in-depth understanding of the speaker's personal perspective on an issue. Monitoring how we express ourselves verbally will ensure that we maximize accurate understanding of what we mean through active dialogue and openness to feedback on our views. (Heaslip, 1993).
