Lesson 8-1 Advanced Airway Instructs students on how to maintain an airway by means of orotracheal intubation virus on ipad buy tinidazole toronto. Included is a review of basic airway skills virus diagram order tinidazole with american express, nasogastric tube insertion for decompression of the stomach of an infant or child patient antibiotic resistance food safety buy 300 mg tinidazole with amex, and orotracheal intubation of adults antibiotic while pregnant buy generic tinidazole 500mg line, infants and children antimicrobial spray discount 500 mg tinidazole with amex. This includes insertion of the nasogastric tube in infant and child patients and orotracheal intubation of adults antibiotic hair loss buy tinidazole overnight delivery, infants and children. Whenever possible, supervised clinical experience will be provided to the students. Each lesson has the following components: Objectives the objectives are divided into three categories: Cognitive, Affective, and Psychomotor. Cognitive Affective Psychomotor mental process- emotional process- physical process- perception feelings muscular activity reasoning intuition To assist with the design and development of a specific lesson, each objective has a numerical value. The first number is the module of instruction, followed by a hyphen and the number of the specific lesson. The number following the type of objective represents the level of objective: 1 = Knowledge; 2 = Application; and 3 = Problem Solving. Preparation Motivation Each lesson has a motivational statement that should be read by the instructor prior to teaching the lesson. It is not the intent for the instructor to necessarily read the motivational statement to the students, but more importantly to be familiar with its content and to be able to prepare the students or explain why this is important. Prerequisites Prior to starting a lesson, the instructor should assure that the students have completed the necessary prerequisites. If possible, the course administrator should have a video library available for the student. Personnel: Program Director Course Coordinator Primary Instructor Assistant Instructor Course Medical Director the roles of the program personnel are discussed in more detail under Program Personnel. Recommended Minimum Time to Complete Each lesson plan has a recommended minimum time for completion. Although the time for each lesson has been pilot tested, due to the varying nature of adult learners, the enrichment and need for remediation may require additional time. Time limits may be extended to bring the students to the full level of competency. This may be accomplished by various methods, including lectures, small group discussion, and the use of audio-visual materials. Demonstrations, if the instructor desires, may be used as part of the instruction. Lesson plans should be considered dynamic documents that provide guidelines for the appropriate flow of information. The lesson plans are based upon changes in national standards and scientific evidence approved by the Course Medical Director. The instructor should feel free to write notes in the margins and make the lesson plan his own. The students should be able to demonstrate competency in all skills listed in each section. If the instructor performed a demonstration as part of the declarative component, the students may begin by practicing skills in the practical setting. When this component of the lesson is being conducted, there should be one instructor for every six students. For those students having difficulty performing a skill or skills, remediation is required. It is well known that a demonstration must be followed by practice, which must be drilled to a level that assures mastery of the skill. It has been proven that demonstration followed as soon as possible by organized, supervised practice enhances mastery and successful applications. It is of utmost importance that the instructor be familiar with the intent of this section and relay that intent to the students. The intent of this section is to assure that the content of the curriculum is presented to meet the needs of the three different types of learning styles. These three areas should not necessarily be used separately from the lesson plan, but as an adjunct to it. An attempt to provide instruction to the student with these three types of modalities will enhance student learning. Auditory (Hear) this section allows the instructor to provide material in a verbal manner. Those students who learn best by hearing will benefit from this method of instruction. Visual (See) this section allows the instructor to provide material in a visual manner. Kinesthetic (Do) this section allows the instructor to provide material in a performance manner. Those students who learn best by doing will benefit from this method of instruction. Instructor Activities this section is to remind the instructors that they should always supervise student practice and praise progress. They should reinforce student progress in cognitive, affective and psychomotor domains. If additional time is needed to complete this task beyond the assigned times of the program, the instructor should complete a remediation form to remind him to schedule additional assistance for the student or group of students experiencing difficulty with the task. Evaluation Written the instructor should design and develop various quizzes, verbal reviews, handouts and any other desired materials for the students. Ideally, the instructor should provide a brief quiz after every lesson to determine if the students are comprehending the lesson. Practical the instructor should provide students with practical evaluations when applicable. The skill sheets provided within the curriculum will assist the students in preparing for field performance and the final practical evaluation. Remediation the intent of this section is to assure that the instructor meets the needs of those students who are experiencing difficulty understanding the lesson plan. Remediation Sheets supplied in this guide will enable the instructor to keep track of those students. If a student requires remediation frequently a decision should be reached to determine if the student should continue in the program (see Appendix G). Enrichment this section is designed to allow the instructors, the course medical director, the course coordinator, the region, or state to add additional information, or augment the curriculum. Anything that is unique to your area should be added, for example, jellyfish injuries that are unique to coastal areas (see Appendix F). As mentioned before, quizzes of the cognitive and psychomotor domains should be provided at the completion of each lesson. Time is allocated at the end of each module of instruction for a cognitive and psychomotor evaluation. The primary instructor in conjunction with the course coordinator is responsible for the design, development, administration and grading of all written and practical examinations. The program should feel free to use outside agency-approved psychomotor evaluation instruments or those found in texts. All written examinations used within the program should be valid and reliable and conform to psychometric standards. Instructors should be encouraged to use outside sources to validate examinations and/or as a source of classroom examination items. The primary purpose of this course is to meet the entry-level job expectations as indicated in the job description. Each student, therefore, must demonstrate attainment of knowledge, attitude, and skills in each area taught in the course. It is the responsibility of the course coordinator, medical director, primary instructor and educational institution to assure that students obtain proficiency in each module of instruction before they proceed to the next area. If after counseling and remediation a student fails to demonstrate the ability to learn specific knowledge, attitudes and skills, the program director should not hesitate to dismiss the student. This is ultimately a reflection on the program director, primary instructor, medical director and educational institution. It is not the responsibility of the certifying examination to assure competency over successful completion of the course. Program directors should recommend only qualified candidates for licensure, certification or registration. Requirements for successful completion of the course are as follows: Cognitive Students must receive passing grades on all module examinations and the final examination. Affective Students must demonstrate conscientiousness and interest in the program. Psychomotor Students must demonstrate proficiency in all skills in each testing session of selected topic areas and mastery of skills in the final examination. Special remedial sessions may be utilized to assist in the completion of a lesson or module of instruction. Usage of the skill measurement instruments within this curriculum or developed by way of a valid process is strongly recommended to achieve maximum results with the students. The additional areas that should be utilized for evaluation of student achievement include: Personal appearance Each student should be neat, clean, well groomed and physically fit enough to perform the minimal entry-level job requirements. Students who fail to exhibit good hygiene habits should be counseled while the program is in session to provide them with the opportunity to correct the habits. At the discretion of the program director or designee, a student missing a lesson may demonstrate the fulfillment of all skills and knowledge covered in the missed lesson. Clinical or Field Rotation Experience Prior to certification of course completion, satisfactory clinical or field experience is required by the student. For clarity, the following terms are defined as they will be used throughout this document. The individuals carrying them out may vary from program to program and from locality to locality as the exact roles interface and overlap. In fact, one person, if qualified, may carry out all of the roles in some programs. While the Program Director is responsible for the overall operation of the education experience, this person need not be qualified or involved in the actual instruction of specific course lessons. The Course Coordinator acts as the liaison between the students, the sponsoring agency, the local medical community and the state-level certifying or licensing agency and is responsible for assuring that the course goals and objectives (and those set forth by any licensing, registering, or certifying agency as applicable) are met. Primary Instructor: this individual is expected to be knowledgeable in all aspects of prehospital emergency care, in the techniques and methods of adult education, and managing resources and personnel. This individual should be present at most, if not all, class ses sions to assure program continuity and to be able to identify that the students have the cognitive, affective and psycho motor skills necessary to function as an Emergency Medical Technician-Basic. This individual should have attended a workshop which reviews the format, philosophy and skills of the new curriculum. Assistant Instructor: this individual assists the primary instructor of any lesson in the demonstration and practice designed to develop and evaluate student skill competencies. The Course Medical Director can assist in recruiting physicians to present materials in class, settling questions of medical protocol and acting as a liaison between the course and the medical community. This Course Medical Director or a designee is responsible to verify student competence in the cognitive, affective and psychomotor domains. Philosophy of the Adult Learner Individuals participating in this educational program should be considered adult learners, even in those programs providing instruction to students younger than age 18. It is less difficult for them to use the concepts and principles they have gained if they are able to participate actively in the learning process. The intent of this revised curriculum is to alter the methods of instruction provided by the instructor. This curriculum has been designed and developed to reduce the amount of lecture time and move towards an environment of discussion and practical skills. If instructors get off to a bad start, it is often because they fail to successfully gain and maintain the attention of the student. In these situations, students start enthusiastic and may leave with some level of disappointment. This may be accomplished by using the information found in the motivational statement or the contextual statement of the lesson plan. Once you have gained the attention of the student, you must then maintain it throughout the entire lesson. After about 15-20 minutes of presentation, it is essential that the student be reinvolved in the learning process. There are three methods often utilized to keep the students active in the process: Questioning, brainstorming, and demonstration. Questions should be used to promote thought, to evaluate what has been learned, and to continuously move students toward their desired goal. It is also appropriate to ask rhetorical questions that are not meant to be answered by the student, but that encourage thinking. Questions should be a significant part of the lesson and should be used in both didactic and practical presentation. Another method of keeping students actively involved in their learning is to use brainstorming. Pose a question to the students and then allow them to provide as many answers as possible. After all the ideas have been presented, move the students toward the appropriate and important points. By providing the students with actual demonstration, you have bridged the gap between theory and practice.

Lifestyle modification and pharmacotherapy are the mainstays of antihypertensive treatment regimens antibiotic given for uti buy tinidazole 300 mg lowest price. The Chicago Heart Association Detection Project in Industry found that antihypertensive therapy reduces the incidence of stroke infection urinaire femme buy 500 mg tinidazole mastercard, myocardial infarction virus that causes hives generic 1000 mg tinidazole amex, and heart failure antibiotics for genital acne order generic tinidazole from india. Additional questions should be asked to supplement the information requested on the Medical Examination Report form antibiotic 1338 discount generic tinidazole uk. You may ask about symptoms of hypertension and use of antihypertensive medications virus buster serge order generic tinidazole from india. It is generally not the role of the medical examiner to determine treatment for the disease. Measure Blood Pressure and Check Pulse Measure Blood Pressure Because of the prevalence of hypertension in the commercial driving population, this routine test is an essential tool as part of the physical examination to determine the medical fitness for duty of the driver. The purpose of the examination is medical fitness for duty, not diagnosis and treatment of the underlying disease. Advisory Criteria/Guidance Essential Hypertension the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure established three stages of hypertension that define the severity of hypertension and guide therapy. It is not intended as a means to indefinitely extend driving privileges for a driver with a condition that is associated with long-term risks. However, all hypertensive drivers should be strongly encouraged to pursue consultation with a primary care provider to ensure appropriate therapy and healthcare education. Treatment should be well tolerated before considering certifying a driver with a history of stage 3 hypertension. Page 68 of 260 this applies to the recertification of the driver who has met the first examination 1-year certification parameters. Follow-up the driver must follow-up on or before the one-time, 3-month certificate expiration date. This means that you use the date on the one Page 70 of 260 time, 3-month certificate to calculate the medical certificate expiration date. Stage 3 Hypertension Stage 3 hypertension carries a high risk for the development of acute hypertension-related symptoms that could impair judgment and driving ability. Meningismus, acute neurological deficits, abrupt onset of shortness of breath, or severe, ripping back or chest pain could signal an impending hypertensive catastrophe that requires immediate cessation of driving and emergency medical care. Symptoms of hypertensive urgency such as headache and nausea are likely to be more subtle, subacute in onset, and more amenable to treatment than a hypertensive emergency. Secondary Hypertension the prevalence of secondary hypertension in the general population is estimated at between 5% and 20%. You should obtain information that assesses the underlying cause, the effectiveness of treatment, and any side effects that may interfere with driving. Examples of primary conditions that may lead to secondary hypertension include pheochromocytoma, primary aldosteronism, renovascular disease, and unilateral renal parenchymal disease. Recommend to certify if: the driver has blood pressure that is less than or equal to 140/90. Both are more common in the commercial driving population than in the general population. This increases the likelihood of changes in arterial tone, myocardial excitability and contractility, and thrombogenic propensity, particularly given the aging workforce in the United States. Sudden cardiac dysfunction is particularly relevant to safety-sensitive positions, such as pilots, merchant marines, and commercial drivers. In these jobs, policies are expected to protect against gradual or sudden incapacitation on the job and harm to the public. The effect of heart disease on driving must be viewed in relation to the general health of the driver. Thus, medical certification to drive depends on a comprehensive medical assessment of overall health and informed medical judgment about the impact of single or multiple conditions on the whole person. As the medical examiner, your fundamental obligation during the cardiovascular assessment is to establish whether a driver has a cardiovascular disease or disorder that increases the risk for sudden death or incapacitation, thus endangering driver and public safety and health. Key Points for Cardiovascular Examination During the physical examination, you should ask the same questions you would of any individual who is being assessed for cardiovascular concerns. Anticoagulant therapy may be utilized in the treatment of cardiovascular or neurological conditions. The guidelines emphasize that the certification decision should be based on the underlying medical disease or disorder requiring medication, not the medication itself. Page 76 of 260 Aneurysms, Peripheral Vascular Disease, and Venous Disease and Treatments the diagnosis of arterial disease should alert you to the need for an evaluation to determine the presence of other cardiovascular diseases. Rupture is the most serious complication of an abdominal aortic aneurysm and is related to the size of the aneurysm. Deep venous thrombosis can be the source of acute pulmonary emboli or lead to long-term venous complications. Intermittent claudication is the primary symptom of peripheral vascular disease of the lower extremities. Detection during a physical examination depends on aneurysm size and is affected by obesity. Monitoring of an aneurysm is advised because the growth rate can vary and rapid expansion can occur. Adequate treatment with anticoagulants decreases the risk of recurrent thrombosis by approximately 80%. Waiting period No recommended time frame You should not certify the driver until etiology is confirmed, and treatment has been shown to be adequate/effective, safe, and stable. Page 78 of 260 To review the Venous Disease Recommendation Tables, see Appendix D of this handbook. Chronic Thrombotic Venous Disease Chronic thrombotic venous disease of the legs increases the risk of pulmonary emboli; however, there is insufficient research to confirm the level of risk. As a medical examiner, you must evaluate on a case-by case basis to determine if the driver meets cardiovascular requirements. Waiting period No recommended time frame You should not certify the driver until etiology is confirmed and treatment has been shown to be adequate/effective, safe, and stable. To review the Venous Disease Recommendation Tables, see Appendix D of this handbook. Intermittent Claudication Approximately 7% to 9% of persons with peripheral vascular disease develop intermittent claudication, the primary symptom of obstructive vascular disease of the lower extremity. In cases of severe arterial insufficiency, necrosis, neuropathy, and atrophy may occur. To review the Peripheral Vascular Disease Recommendation Table, see Appendix D of this handbook. Other Aneurysms Aneurysms can develop in visceral and peripheral arteries and venous vessels. Much of the information on aortic aneurysms is applicable to aneurysms in other arteries. Page 80 of 260 Monitoring/testing You may, on a case-by-case basis, obtain additional tests and consultations to adequately assess driver medical fitness for duty. Peripheral Vascular Disease Aneurysms can develop in visceral and peripheral arteries and venous vessels. Rupture of any of these aneurysms can lead to gradual or sudden incapacitation and death. Monitoring/Testing You may, on a case-by-case basis, obtain additional tests and consultations to adequately assess driver medical fitness for duty. Page 81 of 260 Post-Surgical Repair of Aneurysm With improved surgical outcomes, and without contraindication for surgery, aneurysms can be electively repaired to prevent rupture. The decision by the treating provider not to surgically repair an aneurysm does not mean that the driver can be certified to drive safely. However, a recommendation to surgically repair an aneurysm disqualifies the driver until the aneurysm has been repaired and a satisfactory recovery period has passed. Monitoring/Testing When post-surgical treatment includes anticoagulant therapy, the driver should meet monitoring guidelines. Page 83 of 260 Monitoring/Testing You may on a case-by-case basis obtain additional tests and/or consultation to adequately assess driver medical fitness for duty. Thoracic Aneurysm While relatively rare, thoracic aneurysms are increasing in frequency. Size of the aorta is considered the major factor in determining risk for dissection or rupture of a thoracic aneurysm. Page 84 of 260 Varicose Veins Varicose veins with the associated symptoms and complications affect more than 20 million people in the United States. Complications include chronic venous insufficiency, leg ulcerations, and recurrent deep vein thrombosis. The presence of varicose veins does not medically disqualify the commercial driver. Recommend not to certify if: As the medical examiner, you believe that the nature and severity of the medical condition of the driver endangers the health and safety of the driver and the public. Cardiac Arrhythmias and Treatment the majority of sudden cardiac deaths are thought to be secondary to ventricular tachycardia or ventricular fibrillation and occur most often when there is no prior diagnosis of heart disease. Risk determination is difficult because of the number of variables that must be considered. While defibrillation may restore a normal rhythm, there remains a high risk of recurrence. The management of the underlying disease is not effective enough for the driver to meet cardiovascular qualification requirements. To review the Implantable Defibrillator Recommendation Table, see Appendix D of this handbook. When assessing the risk for sudden, unexpected incapacitation in a driver with a pacemaker, the underlying disease responsible for the pacemaker indication must be considered. Currently, pacemakers and the lead systems are reliable and durable over the long term. Treatment by catheter ablation is usually curative and allows drug therapy to be withdrawn.

Clinical question 22: How should head trauma patients be of chyme reinfusion or enteroclysis should be evaluated and fed No systematic research on safe limits for weight with length of hospitalization and three month function level [332]. Most of the patients [230] are underfed (receiving 58% of the energy Additionally, hypocaloric medical nutrition therapy appears to be requirements, and 53% of the protein requirements). Thus, in an older person with the same body weight, a day may be considered in this population, since there are large lower muscle mass is likely to be present. If indirect calorimetry is not available and nitrogen excretion not measured, we suggest the use of ideal body weight as reference 3. Such an approach would completely In obese patients, energy intake should be guided by indirect ignore the metabolic demand of adipose tissue and muscle.

Applying this knowledge to develop effective therapies for specific subtypes of injury virus x 1948 buy discount tinidazole 300mg on line, rather than for the entire constellation of injuries best antibiotics for sinus infection and bronchitis tinidazole 300 mg on line, is likely the key to developing successful interventions bacteria found on mars buy 500mg tinidazole with amex. Characterizing the pathophysiology and temporal evolution of these subtypes of injury would provide a foundation for identifying therapeutic targets and the window of opportunity for using them antibiotics for uti treatment tinidazole 500mg without a prescription. It would provide the necessary scientific rationale for testing single and combined agents to hit these targets to attenuate injury or promote repair processes virus movies list purchase cheap tinidazole line. A new classification system based on the pathoanatomy antibiotic 7146 cheap tinidazole 300mg with visa, rather than on the Glasgow Coma Scale also would inform chemical biomarker development and correlation of pathology with neuroimaging for these subtypes of injury. Surrogate markers would make it possible to identify people who have these subtypes of injury and also to monitor the biological effects of experimental interventions during clinical trials. This builds upon the previous recommendation because the milder injuries are often less complex than more severe injuries. Developing more effective and efficient approaches for preclinical drug development. An efficient testing system for optimizing the dose and timing and for comparing effectiveness of interventions, alone and in combination, is needed to accelerate therapy development. Ongoing and new research on biomarkers would be accelerated by sharing data and supporting larger, multicenter projects to rapidly obtain greater numbers of samples and subjects. This is also true for advancing the development of neuroimaging and other diagnostic tools and biomarkers and for the validation of outcome measurement tools for clinical trials. A coordinated and collaborative effort would enhance trial designs, increase the rate of subject enrollment and data collection, and optimize statistical analysis and data interpretation. Studies would be completed more quickly, and if successful, this collaborative approach would also facilitate implementation of these valid diagnostic tools, biomarkers, and proven interventions into clinical practice. Moreover, prevalence studies have the potential to identify gaps and guide resource allocation. The agencies are already working together through the Common Data Elements project and this provides one useful forum for regular reviews of important issues. The leading causes of these injuries vary according to age and sex of injured persons. During off-duty hours and those retired from active duty, the risks are similar to the civilian population, with falls and motor vehicle crashes among the major causes. Where evidence-based strategies exist, it is imperative that there is strict adherence to those practices. The recommendations below focus on continued research to reduce risk factors, improve the quality of protective equipment, and ensure that current guidelines and evidence-based strategies are adhered. Research may include but is not limited to reducing use of alcohol, ensuring adherence to use of seatbelts, motorcycle helmets and other protective equipment.
