Records of events along with corrective and preventive actions should be maintained to serve as an opportunity to improve quality management arteria umbilical unica consecuencias isoptin 40 mg order with amex. The requirements of clients should be adequately defned pulse pressure wave 40 mg isoptin purchase free shipping, documented blood pressure kits stethoscope order isoptin 240 mg without a prescription, and understood. The service provider should have procedures in place to ensure that it has the capability of meeting these requirements before entering into a contract. Revised agreements should be documented and effective communication is the key to success (Answer E). Quality assurance is the measurable aspect of processes or outcomes that provide an indication of the condition or direction of performance over time B. Quality indicators are measurable aspects of only outcomes which can be used objectively to evaluate a process C. Quality management involves interrelated processes in the context of an organization and its relations with customers and suppliers D. Quality indicators include operational techniques and activities that are used to monitor and eliminate causes of unsatisfactory performance at any stage of a process E. Quality control is a dynamic model that includes retrospective reviews and analyses of operational performance data to detect shifts or trends that require attention Concept: Quality includes various aspects, such as quality control, quality assurance, quality indicators, and a quality management system. Quality assurance (Answer A) is a dynamic model that includes retrospective reviews and analyses of operational performance data to detect shifts or trends that require attention. It includes systematic measurement, comparison with standards, monitoring of processes, and an associated feedback loop that confers error prevention. It is a system designed and implemented to ensure that testing is consistently performed in such a way as to yield a product of consistent quality. Quality control includes operational techniques and activities used to monitor and eliminate causes of unsatisfactory performance at any stage of a process. Laboratory control procedures must include adequate provisions for monitoring the reliability, accuracy, precision, and performance of laboratory test procedures and instruments. Quality indicators (Answers B and D) are used to monitor the progress toward stated goals and may be process-based or outcome-based (measurable aspects of processes and outcomes). A formal quality assurance program is a regulatory requirement by which of the following? Laboratories must establish and follow written policies and procedures for a comprehensive quality assurance program that is designed to monitor and evaluate the ongoing and overall quality of the total testing process. Its mission is to develop and deliver standards, accreditation, and educational programs that focus on patient and donor care and safety. It promotes excellence in laboratory medicine and patient care through voluntary education, consultation, and accreditation. A batch of 15 patient samples for type and screen are loaded on the automated analyzer. At the end of the run, you note that the positive control on forward typing with anti-A reagent gives erroneous results. Check the records for documentation that the correct steps of testing were followed B. Report and release the test results, but with a footnote stating failure of the positive control C. Check the quality control log to see if there was a similar problem in previous runs E. Answer: B—In event of a failure of internal control, the corrective actions should be taken without delay and the results should not be reported until the error is fxed. The log should identify the name of the test, the instrument, units, the date on which the test is performed, the initials of the person performing the test, and the results for each level of control assayed. Other choices (Answers A, C, D, and E) represented appropriate actions to handle “control failure”. Which of the following is true regarding the performance and analysis of quality control? Quality control records and logs are reported using a Levey-Jennings chart in the paper or electronic-based system B. Obtaining quantitative data is the primary objective of quality control analysis C. Random error is inherent in every test system and does not have to be investigated D. External quality control is performed only when internal quality control is suboptimal Concept: Quality control records provide evidence that critical steps in a procedure have been appropriately performed and that products and services conform to special requirements.

Likewise arteria 66 buy isoptin mastercard, if 0 is not in the 95% confdence interval blood pressure diastolic high purchase genuine isoptin line, then there is evidence of constant bias between the assays blood pressure natural cheap isoptin 120 mg on-line. In this example, there is statistically signifcant evidence that there is both proportional difference (because the 95% confdence interval for the slope did not contain 1) and constant bias (because the 95% confdence interval for the intercept did not contain 0). This is important information because if assay 1 is the “gold standard,” then modifcations, such as recalibration, must be made to assay 2 measurements before it can be used in the clinical laboratory. Answer: D—Although assay 1 and assay 2 have excellent correlation, assay 2 has both signifcant proportional and constant bias compared to assay 1 based on the results of the Deming regression analysis. The remaining choices (Answers A, B, C, and E) are incorrect interpretations based on the explanation above. End of Case Please answer Questions 10–12 based on the following scenario: You are the Medical Director for the Peripheral Blood and Bone Marrow Hematopoietic Progenitor Cell Processing Laboratory at your hospital. Durability studies on the freezer Concept: Before an instrument is placed into use in a clinical laboratory, a validation study must be performed to demonstrate that the instrument will meet specifcations and fulfll the intended purpose. Validation will test the mechanical freezer to ensure that the freezing process will work similar to the controlled-rate freezer in the actual live environment, as part of the required contingency plan. Answer: A—As explained earlier, the mechanical/backup freezer must be validated before being accepted for use. Reliability studies (Answer B) are performed on clinical laboratory tests, when assessing accuracy and precision while temperature-controlled studies are not conducted on a mechanical freezer. Linearity studies are most commonly done for analytes, to determine if the instrument measurements are consistent with expected values (Answer D). Heat tolerance studies (Answer C) would not test the desired function of the freezer, and durability studies (Answer E) are carried out by the manufacturer. Medical director, stem cell processing laboratory Concept: Validation of laboratory equipment is important not only for meeting regulatory requirements, but also for producing high-quality results and patient care. Each member of the laboratory participates in this process with varying degrees of responsibility. Answer: E—The medical director, the manager, and the technologist(s) in the stem cell laboratory should all be involved in writing a protocol for the validation study. The protocol should include the purpose of validation, the process description, responsibilities, the materials required, test samples required, testing conditions, data collection, acceptance criteria, and conclusions. The study results are reviewed by the laboratory manager and the medical director; however, the ultimate responsibility and approval rests with the medical director. All of the other choices (Answers A, B, C, and D) are incorrect, even though some of them contain personnel that might be involved in a validation (e. The stem cell laboratory may compare its results with other laboratories before reporting the results D. Your technologist should test/treat the sample as they would treat a normal sample. In the absence of an approved program, laboratories must have a system of determining accuracy and reliability of test results. Repeat testing is permitted provided that the patient samples are tested in similar manner (Answer A). Laboratories may not discuss a profciency test results with other laboratories (i. Failure to achieve a satisfactory score requires corrective action or suspension of testing (Answer D). The corrective action will be prepared to include retraining of the testing personnel to achieve competency and the action plan must be approved by the accrediting agency. Failure to attain a satisfactory score on 3 out of 4 testing events is considered critical profciency testing performance and requires immediate suspension of testing. Accuracy describes how close the measurement is to the “true” result measured by the “gold standard” method. Mean commonly refers to the arithmetic mean of the measurements, which can be expressed as  1  n mean   1 xi (where n is the number of measurements, and the ith measurement is represented as mean=(1n)O1nxi  n xi). Then, this level is compared with the manufacturer’s claim (if available), and if it is less than the manufacturer’s claim, then it passes the “limit of detection” test.

Endocarditis: Surgical indications: intractable heart failure; persistent infection; large mobile vegetations; peripheral embolism; and valve dehiscence, perforation, rupture or fistula, or a large perivalvular abscess. Children with congenital heart disease are more likely to have more turbulent cardiovascular blood flow, which increases risk of endovascular infection. Immunocompromised hosts may become bacteremic with a wide range of bacteria, fungi, and mycobacteria. Prospective, controlled data on therapy for endocarditis in neonates, infants, and children is quite limited, and many recommendations provided are extrapolations from adults, where some level of evidence exists, or from other invasive bacteremia infections.

Persistent median artery is sometimes associated with high division or bifd median nerve heart attack 30 year old woman cheap isoptin 40 mg otc, in which cases the artery is often in the middle of the divided nerve. When the persistent median artery is eccentrically located with respect to the nerve, the block should target the nonarterial side of the nerve to avoid intraneural hematoma. Motor block of the opponens pollicis can be tested by having the patient touch the base of the small fnger with the thumb against resistance.

For in-plane technique, the needle approaches from the lateral aspect of the forearm. Sonograms illustrating the in-plane (A) and out-of-plane (B) approaches to median nerve block. Because the local anesthetic is primarily distributed over the surface of the nerve, additional local anesthetic is then deposited underneath the nerve. In this variation the persistent median artery lies within the same connective tissue bundle as the median nerve and can divide it into two parts. When this condition is identifed, the needle tip is placed on the side of the nerve away from the artery. The ulnar nerve provides sensation of the dorsal and palmar sides of the ulnar aspect of the hand. It leaves the neurovascular bundle in the axilla to travel through the cubital tunnel. The dorsal cutaneous 1,2 branch leaves the ulnar nerve in the forearm proximal to the wrist. At the level of the hamate, the ulnar nerve divides into its superfcial sensory branch and its deep motor branch. Suggested Technique The ulnar nerve is usually blocked just proximal to its juncture with the ulnar artery in the 3 forearm. The needle tip is placed within the fascial plane that connects the ulnar nerve and ulnar artery using an in-plane approach from the lateral side of the forearm. To access this plane with the block needle it is best to puncture the fascia and slowly inject as the needle is pulled back. A relatively common (3%-10%) anatomic variant is superfcial ulnar artery, whereby the 4 ulnar artery lies superfcial to the fexor muscles. Neurologic Assessment Neurologic assessment of ulnar nerve block includes testing sensation of the ulnar side of the hand. Motor block assessment can be performed by testing the dorsal and palmar inter- ossei functions. The dorsal cutaneous branch of the ulnar nerve: an anatomic clarifcation with six case reports. An in-plane approach is demonstrated whereby the needle tip is placed between the ulnar artery and ulnar nerve (A and B). After injection, local anesthetic is distributed around the ulnar nerve (C) and tracks along the nerve (D). In this variation, the ulnar artery lies superfcial to the fexor muscles and is not adjacent to the ulnar nerve.

There is diminished oxidation of long-chain fatty acids and increased use of glucose as a secondary fuel source during ischemia or hibernation blood pressure medication for nightmares buy genuine isoptin line. The release of this product of β-oxidation is reflective of long-chain fatty acid oxidation in myocardium. Measuring the production of [ C]carbon dioxide in this setting correlates with myocardial oxygen consumption. An attenuation scan is performed that allows the density of the surrounding thoracic structures to be subtracted to leave only cardiac count activity. After the attenuation scan, the positron-emitting radiopharmaceutical is injected, and images are obtained 2 to 5 minutes later. As mentioned earlier in the chapter, two photons are created by the annihilation of the emitted positron colliding with the nearest electron it meets in the tissue surrounding it. These two photons travel exactly 180° apart while the patient is lying in the circular scanner. The detector/analyzer merely has to “accept” the signal it receives only if a simultaneous signal strikes the detector directly across from it in the scanner. This dramatically improves the signal-to-noise ratio that can be achieved during imaging. As mentioned before, the ability to quantitate absolute blood flow regionally and globally may help improve the diagnosis of coronary ischemia in the setting of severe multivessel disease and balanced ischemia. The presence of a flow–metabolism mismatch, which indicates underperfusion in the presence of metabolically active myocytes, suggests hibernating myocardium. This utility of nuclear imaging has found increasing application in the selection of patients for revascularization who have ischemic cardiomyopathy and heart failure with low ejection fraction. Under fasting conditions, myocardial cells shift to utilizing predominantly fatty acids. Inflammatory cells in cardiac sarcoidosis utilize glucose because of high metabolic demands, even during fasting. Sarcoidosis nuclear protocols vary among institutions, but attempt to minimize physiologic glucose uptake in normal myocardial tissue. Patients are advised to prepare for the exam with a prolonged fast (12 to 18 hours) and high-protein, low-carbohydrate diet the day before the exam.

Myocardial oxygen demand is determined by contractility (inotropy), heart rate (chronotropy), and wall stress (preload + afterload). Although a number of agents have been evaluated in combination with echocardiography, dobutamine is most widely used. Low-dose dobutamine has positive inotropic effects mediated through cardiac α - and β -receptors. At higher doses, it has positive1 1 chronotropic effects mediated through β -receptors. These agents result in perfusion abnormalities by causing blood to be preferentially shunted away from myocardial segments supplied by stenotic coronary arteries (i. However, because of the shorter duration of action of adenosine, the echocardiographic findings tend to be less pronounced and of shorter duration, resulting in a lower sensitivity.

The frst offcer repeated attempts to intubate the patient may worsen the brought this to the attention of the captain who has the situation resulting in the feared combination of cannot sole authority to reject the take off. They tion attempts and yet anaesthetists still have a tendency to continued the take off at a reduced power setting (because persist in this path (Shiva factor 4). This buys thinking issued the appropriate warnings (no failure of technology) time, so that additional technology may be brought in they failed to push the thrust levers fully up (failure of (diffcult airway equipment), additional profciency may profciency and judgement). That simple action, taken at be added (more/different personnel), guidelines can be the right time, might have averted the disaster. Every critical aspect of fight, and the condi- tions along the way, represents a potential threat that could cause the pilots to err. The details of the fight plan and the reasons behind each deci- sion are fully discussed and understood by everyone. The core purpose of the briefng is to establish a mutual mental model between crew members prior to departure and, equally importantly, to provide the opportunity for any additional information, relevant experience, or even subjective opinion, to be aired and added to the crews’ collective situational awareness. It is recognized here that a steep authority gradient stifes information fow and a ‘superior’ attitude can induce stress and provoke errors in the subordinate. The preparedness consequent to adequate and appropriate planning and briefng affords the crew more mental capacity when variances Figure 29. In aviation, checklists are used in both normal and At particularly crucial phases of fight, i. They may be done individually or landing, the briefng rate increases and the ‘challenge/ in a pair, with one pilot doing and the other confrming response’ use of checklists becomes more critical in error each step. For abnormal checklists, ronment is considered replete with potential ‘threats’ there may be a quick reference handbook, with supple- which, if they do not recognize and manage, will cause mental information in a pilot handbook. The greater the understanding situation in anaesthesia would be a cardiac arrest due of the threat posed by the circumstances, the less the to local anaesthetic, where one would initially refer likelihood of error arising. Perhaps one of the most successful training initiatives In an emergency situation, such as an engine fre, the has been the introduction, in the late 1980s, of ‘real-time’ approach was to use a memorized checklist. However, in highly stressful situations, of one’s own thinking process) aspect of aircrew training. The ‘consequences’ example would be a rapid decompression incident where are the product of the quality of the decisions and subse- the frst step is that the pilot must secure his or her oxygen quent actions. It is virtually certain that successively poor mask, subsequent steps are done using a checklist. Crews experience non-fying pilot reads and performs each step on the the outcome of their own decision pathways in a safe learn- checklist, the fying pilot confrms steps, but has no other ing environment. An example from using human factors guidelines as performance criteria, anaesthesia would be the management of malignant with an instructor who is specifcally accredited in this hyperthermia. An example from aviation Checklists are specifcally addressed below, whilst the other categories are referred to in context in the text On British Midland Flight 92, on 8 January 1989, cross adjoining this section. There were other indicators available to allow Checklists the correct course of action. The air- use of checklists can empower subordinates to insist on craft crashed on a motorway just short of the runway with the adherence to approved and safe procedures. In analyzing the event, if attention is only on the trainee, then the opportunity to ‘fx the system’ will be missed. If, however, the response is to impose a ‘sign off’ of a written equipment checklist and to prohibit inexperienced anaes- thetists from working alone in remote areas, then many more critical situations will be prevented. In this scenario technology can not be improved upon: reservoir bags cannot be made indestructible. Lack of profciency will make the outcome worse if the anaesthetist does not have the knowledge and skills to carry out the necessary emergency procedures. Standard operating procedure will greatly assist the team in this situation: use of a self- infating bag in the frst instance and a call for senior help. He must recognize that the situation has changed and he must not ‘posture’ but must declare the emergency and get appropriate help. Anaesthetists can take many important lessons from avia- tion and can usefully adopt tools, such as checklists and An example from anaesthesia standard operating procedures, into their practice.

Literature reviews often include both the theoretical approaches to your topic and research (empirical or analytical) on your topic. Writing the Literature Review Allows Understanding • How other researchers/scholars have written about the topic? The literature review has four major functions that you should keep in mind as you write: • It situates the current study within a wider disciplinary conversation. Effective Literature Reviews Should– • Take out the Introduction’s brief description of the background of your study. Tips on Drafting Your Literature Review • Categorize the literature into recognizable topic clusters and begin each with a sub-heading. Demonstrate the places where the literature is lacking, whether due to a methodology you think is incomplete or to assumptions you think are flawed. You should be tying the literature you review to specific facets of your problem, not to review for the sake of reviewing. As tempting as it might be to throw in everything you know, the literature review is not the place for such demonstration. Stick to those pieces of the literature directly relevant to your narrowed subject (question or statement of a problem). You should fight the temptation to strongly express your opinions about the previous literature. Your task is to justify your project given the known scholarship, so polemics, praise, and blame are unnecessary and possibly distracting. Key Points: After assessing the literature in your field, you should be able to answer the following questions: • Why should we study (further) this research topic/problem? Materials and Methods This section is essential and important to most good research proposals. This section includes a description of the general means through which the goals of the study will be achieved: Methods, materials, procedures, tasks, etc. An effective methodology section should: • Introduce the overall methodological approach for each problem or question. Are you going to take a special approach, such as action research, or use case studies? Your methods should have a clear connection with your research questions and/or hypotheses. In other words, make sure that your methods will actually answer your questions or stated objectives, i. One should also include inclusion, exclusion, eligibility and diagnostic criteria especially in medical and health research. Will you use specific theoretical perspectives to help you analyze a text or explain observed behaviors? For instance, if you propose to conduct interviews and use questionnaires, how do you intend to select the sample population? The description of the results of your work is the heart of your thesis/dissertation. In this section you might like to include illustrations, like photograph, sector graphs histograms, pie charts, tables and so on. Remember that illustrations should not be used as ornaments but should support the text and aid in clear description and concise explanations, use them to help convey the information accurately and succinctly. All photographs should have a figure number written in Arabic numerals a short caption or legend and in case of photomicrographs the stain used and magnification should be written, e. Punctuators particularly commas, full stops and quotation marks should be used carefully as wrong usage can alter the meaning totally for example– Go, slow work in progress. It is in the discussion that the author incorporates his contribution into existing knowledge. At its fullest, the discussion will want to do lots of things; it should recapitulate the main findings, discuss the methods you used if there is something interesting or unusual about them, discuss the results of other people those that conflict with yours and those that confirm them and argue the case of your results against those that conflict saying why yours are more convincing.

Murat, 39 years: In addition, patients were assessed for a cytogenetic response with bone marrow biopsies to assess the percentage of cells positive for the Philadelphia chromosome during metaphase (0% = com- plete response; 1%–35% = partial response; 36%–65% = minor response; and >65% = absent response).

Hyperactive bowel sounds of a high-pitched tinkling character with distention and obstipation suggest intestinal obstruction. After another 2 days, the patient’s red cell antibody screen is positive, anti-K antibodies are identifed in the patient’s plasma, and the autocontrol is positive.

Some pacemakers can be put in a passive mode in which they store information in order to predict how the pacer would act if set to rate-responsive behavior. Similar to vasopressors, they are used temporarily to maintain perfusion pressure until insertion of mechanical support. Annually, there are nearly 800,000 strokes in the United States and 15 million strokes worldwide.

Peer, 43 years: The absence of the need to purify the suspect colonies allows for a much faster turnaround time. A healthy papilla conforms to the space between two teeth (interproximal space), so from the facial view it comes to a point near where the adjacent teeth contact. These modifcations included widening of the aperture at the frame to iv allow for more room for instruments and the camera, as well as new blades for exposure of the supraglottis (Fig. The laboratory workup should include x-rays of the involved area and of the cervical spine, especially if there is a radicular distribution of the pain.

Hurit, 55 years: Lesions are usually located in the metaphysis of long tubular bones and the spine. Introjectively depressive individuals berate themselves for real or imagined short- comings, and they respond to setbacks with the conviction that they are somehow to blame (a tendency that cognitive therapists have described in terms of “attributional style”; e. If (15 mg/kg), Cycloserine (10 mg/kg), Ethionamide possible, the placenta should be examined and (15 mg/kg), Para-aminosalicylic acid (150-200 mg/ cultured for tubercle bacilli. For example, there is emerg- ing research evidence that supportive–expressive therapies work better with patients with anaclitic psychologies, at least initially, whereas interpretive interventions are preferable for those with introjective personality structures (Blatt, 2006; Blatt, Zuroff, Hawley, & Auerbach, 2010).

Angar, 31 years: Normal pressure hydrocephalus Final Diagnosis: Normal pressure hydrocephalus was confirmed by radioactive cisternography. Although discontinuing transfusions and replacing it with hydroxyurea therapy (Answer D) and phlebotomy (Answer E) has been studied, it is unlikely to be better than chronic transfusion with chelation therapy. If gonococcal arthritis is suspected, urethral or cervical smears and cultures will be helpful, but culture of the fluid on special medium is most important. Weight Loss The examination of a patient with weight loss demands a thorough routine physical examination (see page 444).
