of books, published by the F. A. Davis Company, designed to assist the student nurse in being successful in nursing school and in taking examinations, particularly the NCLEX-RN examination for licensure as a registered nurse. Med-Surg Success: A Course Review Applying Critical Thinking to Test Taking focuses, as its name implies, on critical thinking as it pertains to test-taking skills for examinations in the nursing ? ld. It c ontains the usual practice test questions found in review books, but it also provides important test-taking hints to help in analyzing questions and determining the correct answers. It follows book one of this series— Fundamentals Success: A Course Review Applying Critical Thinking to Test Taking by Patricia Nugent, RN, MA, MS, EdD, and Barbara Vitale, RN, MA—which de? nes critical thinking and the RACE model for applying critical thinking to test taking, but it does not repeat the same speci? c topics.Rather, it focuses on how to use the thinking processes and test-taking skills in answering questions on topics speci? cally addressed in the NCLEX-RN exam and in other nursing exams. Test-taking skills and hints are valuable, but the student and future test taker must remember that the most important aspect of taking any examination is to become knowledgeable about the subject matter the test will cover. There is no substitute for studying the material. 1 GUIDELINES FOR USING THIS BOOK This book contains 19 chapters and a ? nal comprehensive examination. This ntroductory chapter on test taking focuses on guidelines for studying and preparing for an examination, speci? cs about the nature of the NCLEX-RN test and the types of questions contained in it, and approaches to analyzing the questions and determining the correct answer using the RACE model. Thirteen chapters (Chapters 2–14) focus on disorders affecting the different major body systems. Each of these chapters is divided into four major sections: Practice Questions, Practice Questions Answers and Rationales, a Comprehensive Examination, and Comprehensive Examination Answers and Rationales.Key words and abbreviations are also included in each chapter. Different types of multiple-choice questions about disorders that affect a speci? c body system help the test taker to more easily identify speci? c content. The answers to these questions, the explanations for the correct answers, and th e reasons why other possible answer options are wrong or not the best choice reinforce the test taker’s knowledge and ability to discern subtle points in the question. Finally, the test-taking hints provide some clues and tips for answering the speci? c question.The Comprehensive Examination includes questions about the disorders covered in the practice section and questions about other diseases/disorders that may affect the particular body system. Answers and rationales for these examination questions are given, but test-taking hints are not. Chapters 15–18 follow the same pattern but focus on emergency nursing, perioperative nursing, cultural nursing and alternative health care, and end-of-life issues. Chapter 19, the pharmacology chapter, deals speci? cally with what the student nurse should know about the administration of medications, provides test-taking tips speci? to pharmacology questions, and provides questions and answers. A ? nal 100-question comprehensive examination completes the main part of the book. 1 2 Test Taking MED-SURG SUCCESS PREPARING FOR LECTURE To prepare for attending a class on a speci? c topic, students should read the assignment in the textbook and prepare notes to take to class. Highlight any information the test taker does not understand so that the information may be clari? ed during class or, if the instructor does not cover it in class, after the lecture. Writing a prep sheet while reading (studying) is very useful.A single sheet of paper divided into categories of information, as shown in the following, should be sufficient for learning about most disease processes. If students cannot limit the information to one page, they are probably not being discriminatory when reading. The idea is not to rewrite the textbook; the idea is to glean from the textbook the important, need-to-know information. Sample Prep Sheet Medical Diagnosis: Diagnostic Tests: (List normal values) De? nition: Signs and Symptoms Nursing Inte rventions: (Include Teaching)Procedures and Nursing Implications: Medical Interventions: Complete the prep sheet in one color ink. Take the prep sheet to class along with a pen with different color ink or a pencil and a highlighter. Highlight on the prep sheet whatever the instructor emphasizes during the lecture. Write in different color ink or with a pencil any information the instructor emphasizes in lecture that the student did not include on the prep sheet. After the lecture, reread the information in the textbook that was included in the lecture but not on the student’s prep sheet.By using this method when studying for the exam, the test taker will be able to identify the information obtained from the textbook and the information obtained in class. The information on the prep sheet that is highlighted represents information that the test taker thought was important from reading the textbook and that the instructor emphasized during lecture. This is need-to know-informat ion for the examination. Please note, however, that the instructor may not emphasize laboratory tests and values but still expect the student to realize the importance of this information.Carry the completed prep sheets in a folder so that it can be reviewed any time there is a minute that is spent idly, such as during children’s sports practices or when waiting for an appointment. This is learning to make the most of limited time. The prep sheets also should be carried to clinical assignments to use when caring for clients in the hospital. If students are prepared prior to attending class, they will ? nd the lecture easier to understand and, as a result, will be more successful during examinations.Being prepared allows students to listen to the instructor and not sit in class trying to write every word from the overhead presentation. Test takers should recognize the importance of the instructor’s hints during the lecture. The instructor may emphasize information by hi ghlighting areas on overhead slides, by repeating information, or by emphasizing a particular fact. This usually means the instruc- CHAPTER 1 FUNDAMENTALS OF CRITICAL THINKING RELATED TO TEST TAKING 3 Test Taking tor thinks the information is very important. Important information usually ? nds its way onto tests at some point.PREPARING FOR AN EXAMINATION There are several steps that the test taker should take in preparing for an examination— some during the course of the class and some immediately before the day of the test. Study, Identify Weaknesses, and Practice The test taker should plan to study three (3) hours for every one (1) hour of class. For example, a course that is three (3) hours of credit requires nine (9) hours of study a week. Cramming immediately prior to the test usually places the test taker at risk for being unsuccessful. The information acquired during cramming is not really learned and is quickly forgotten.And remember: Nursing examinations include mate rial required by the registered nurse when caring for clients at the bedside. The ? rst time many students realize they do not understand some information is during the examination or, in other words, when it is too late. Nursing examinations contain highlevel application questions requiring the test taker to have memorized information and to be able to interpret the data and make a judgment as to the correct course of action. The test taker must recognize areas of weakness prior to seeing the examination for the ? rst time.This book is designed to provide assistance in identifying areas of weakness prior to the examination. Two to 3 days prior to the examination the test taker should compose a practice test or take any practice questions or comprehensive exams in this book that have not already been answered. If a speci? c topic of study—say, the circulatory system and its disorders—proves to be an area of strength, as evidenced by selecting the correct answers to the questions on that system, then the test taker should proceed to study other areas identi? ed as areas of weakness because of incorrect answers in those areas.Prospective test takers who do not understand the rationale for the correct answer should read the appropriate part of the textbook and try to understand the rationale for the correct answer. However, test takers should be cautious when reading the rationale for the incorrect answer options because during the actual examination, the student may remember reading the information and become confused about whether the information applied to the correct answer or to the incorrect option. The Night Before the Exam The night before the examination the test taker should stop studying by 6:00 P.M. or 7:00 P. M. and then do something fun or relaxing until bedtime. Don’t make bedtime too late: A good night’s rest is essential prior to taking the examination. Studying until bedtime or an all-night cram session will leave the test taker tired and sleepy during the examination, just when the mind should be at its top performance. The Day of the Exam Eat a meal before an examination. A source of carbohydrate for energy, along with a protein source, make a good meal prior to an examination. Skipping a meal before the examination leaves the brain without nourishment.A glass of milk and a bagel with peanut butter is an excellent meal; it provides a source of protein and a sustained release of carbohydrates. Do not eat donuts or other junk food or drink soft drinks. They provide energy that is quickly available but will not last throughout the time required for an examination. Excessive ? uid intake may cause the need to urinate during the examination and make it hard for students to concentrate. 4 Test Taking MED-SURG SUCCESS Test-Taking Anxiety Test takers who have test-taking anxiety should arrive at the testing site 45 minutes prior to the examination.Find a seat for the examination and place books there to reserve the desk. Walk for 15 minutes at a fast pace away from the testing site and then turn and walk back. This exercise literally walks anxiety away. If other test takers’ getting up and leaving the room is bothersome, try to get a desk away from the group, in front of the room or facing a wall. Most schools allow students to wear hunter’s earplugs during a test if noise bothers them. Most RN-NCLEX test sites will provide earplugs if the test taker requests them. TAKING THE EXAM The NCLEX-RN examination is a computerized exam. Tests given in nursing schools in speci? subject areas may be computerized or pen and pencil. Both formats include multiple-choice questions and may include several types of alternate questions: a ? ll-in-theblank question that tests math abilities; a select-all-that-apply question that requires the test taker to select more than one option as the correct answer; a prioritizing question that requires the test taker to prioritize the answers 1, 2, 3, 4, and 5 in the order of when the nurse would implement the intervention; and, in the computerized version, a click-and-drag question that requires the test taker to identify a speci? area of the body as the correct answer. Examples of all types of questions are included in this book. In an attempt to illustrate the click-and-drag question, this book has pictures with lines to delineate choices A, B, C, or D. Refer to the National Council of State Boards of Nursing for additional information on the NCLEX-RN examination (http://www. ncsbn. org). Pen-and-Pencil Exam A test taker taking a pen-and-pencil examination in nursing school who ? nds a question that contains totally unknown information should circle the question and skip it. Another question may help to answer the skipped question.Not moving on and worrying over a question will place success on the next few questions in jeopardy. The mind will not let go of the worry, and this may lead to missing important informatio n in subsequent questions. Computerized Test The computerized NCLEX-RN test is composed of from 75 (the minimum number of questions) to 265 questions. The computer determines with a 95% certainty whether the test taker’s ability is above the passing standard before the examination concludes. During the NCLEX-RN computerized test, take some deep breaths and then select an answer.The computer does not allow the test taker to return to a question. Test takers who become anxious during an examination should stop, put their hands in their lap, close their eyes, and take a minimum of ? ve deep breaths before resuming the examination. Test takers must become aware of personal body signals that indicate increasing stress levels. Some people get gastrointestinal symptoms and others feel a tightening of muscles. Test takers should not be overly concerned if they possess only rudimentary computer skills. Simply use the mouse to select the correct answer.Every question asks for a con? rm ation before being submitted as the correct answer. In addition to typing in pertinent personal information, test takers must be able to type numbers and use the drop-down computer calculator. However, test takers can request an erasable slate to calculate math problems by hand. Practice taking tests on the computer before taking the NCLEX-RN examination. Many textbooks contain computer disks with test questions, and there are many on-line review opportunities. CHAPTER 1 FUNDAMENTALS OF CRITICAL THINKING RELATED TO TEST TAKING 5 Test TakingUNDERSTANDING THE TYPES OF NURSING QUESTIONS Components of a Multiple-Choice Question A multiple-choice question is called an item. Each item has two parts. The stem is the part that contains the information that identi? es the topic and its parameters and then asks a question. The second part consists of one or more possible responses, which are called options. One of the options is the correct answer; the others are the wrong answers and are cal led distracters. The client diagnosed with angina complains of chest pain while ambulating in the hall. Which intervention should the nurse implement ? rst? . Have the client sit down. 2. Monitor the pulse oximeter reading. 3. Administer sublingual nitroglycerin. 4. Apply oxygen via nasal cannula. } STEM } OPTIONS } } CORRECT ANSWER DISTRACTERS Cognitive Levels of Nursing Questions Questions on nursing examinations re? ect a variety of thinking processes that nurses use when caring for clients. These thinking processes are part of the cognitive domain, and they progress from the simple to the complex, from the concrete to the abstract, and from the tangible to the intangible. There are four types of thinking processes represented by nursing questions. . Knowledge Questions—These questions emphasize recalling information that has been learned/studied. 2.

THE RACE MODEL: THE APPLICATION OF CRITICAL THINKING TO MULTIPLE-CHOICE QUESTIONS Answering a test question is like participating in a race.Of course, each test taker wants to come in ? rst and be the winner. However, the thing to remember about a race is that success is not just based on speed but also on strategy and tactics. The same is true about nursing examinations. Although speed may be a variable that must be considered when taking a timed test so that the amount of time spent on each question is factored into the test strategy, the emphasis on RACE is the use of critical-thinking techniques to answer multiplechoice questions. The RACE Model presented here is a critical-thinking strategy to use when answering multiple-choice questions co ncerning nursing.If the test taker follows the RACE Model every time when looking at and analyzing a test question, its use will become second nature. 6 Test Taking MED-SURG SUCCESS This methodical approach will improve the ability to critically analyze a test question and improve the chances of selecting the correct answer. The RACE Model has four steps to answering a test question. The best way to remember the four steps is to refer to the acronym RACE. R — Recognize †¢ What information is in the stem. †¢ The key words in the stem. †¢ Who the client is in the stem. What the topic is about. A — Ask †¢ What is the question asking? †¢ What are the key words in the stem that indicate the need for a response? †¢ What is the question asking the nurse to implement? C — Critically analyze †¢ The options in relation to the question asked in the stem. †¢ Each option in relation to the information in the stem. †¢ A rationale f or each option. †¢ By comparing and contrasting the options in relation to the information in the stem and their relationships to one another. E — Eliminate options †¢ One option at a time. †¢ As many options as possible.The text Fundamentals Success: Course Review Applying Critical Thinking to Test Taking by Patricia Nugent and Barbara Vitale includes a discussion exploring the RACE Model in depth and its relation to the thinking processes used in multiple-choice questions in the ? eld of nursing. The ? rst step toward knowledge is to know that we are not ignorant. —Richard Cecil Neurological Disorders Test-taking hints are useful to discriminate information, but they cannot substitute for knowledge. The student should refer to Chapter 1 for assistance in preparing for class, studying, and taking an examination. This hapter focuses on disorders that affect the neurological system. It provides a list of keywords and abbreviations, practice questions focu sed on disease processes, and a comprehensive examination that includes other content areas involving the neurological system and the disease processes addressed in the practice questions. Answers and reasons why the answer options provided are either correct or incorrect are also provided as are some testtaking hints. The following chapters (Chapters 3–12) focus on disorders that affect other body systems and function. 2 KEYWORDS agnosia akinesia aphasia apraxia are? xia ataxia autonomic dysre? exia bradykinesia decarboxylase diplopia dysarthria dysphagia echolalia epilepsy papilledema paralysis paresthesia paroxysms penumbra postictal ABBREVIATIONS Activities of Daily Living (ADLs) Amyotrophic Lateral Sclerosis (ALS) As Soon As Possible (ASAP) Blood Pressure (BP) Cerebrovascular Accident (CVA) Computed Tomography (CT) Electroencephalogram (EEG) Electromyelogram (EMG) Emergency Department (ED) Enzyme-Linked Immunoassay (ELISA) Health-Care Provider (HCP) Intracranial Pressure (ICP) Intensive Care Department (ICD) Intravenous (IV) Magnetic Resonance Imaging (MRI) Nonsteroidal Anti-In? mmatory Drug (NSAID) Nothing By Mouth (NPO) Parkinson’s Disease (PD) Pulse (P) Range of Motion (ROM) Respiration (R) Rule Out (R/O) Spinal Cord Injury (SCI) STAT—immediately (STAT) Temperature (T) Transient Ischemic Attack (TIA) Traumatic Brain Injury (TBI) Unlicensed Assistive Personnel (UAP) Please note: The term health-care provider, as used in this text, refers to a nurse practitioner (NP), physician (MD), osteopath (DO), or physician assistant (PA) who has prescriptive authority.
