- Open in new tab Analytical errors are of 2 types: random or systematic, and systematic errors can be subdivided further into constant or proportional error. Random errors can be caused by timing, temperature, or pipetting variations that occur randomly during the measurement process and are independent of the operator performing the measurement. Adapted from Ref 1. Figure 1A Laboratory errors in stat testing. The top 5 causes of preanalytical errors were: 1 Specimen collection tube not filled properly. Patient ID error. Test request error. Empty collection tube. Although The menu of laboratory tests available to clinicians constitutes an impressive array that has expanded exponentially since when Folin and Wu devised the first useful test for the quantification of serum glucose concentration.Link: https://collegedisha.com/exams/amu/exam-answer-key
- Despite this ever-expanding plethora of useful and reliable clinical laboratory tests for diagnosing and monitoring the myriad of diseases effecting mankind, the recent emphasis on reducing health care costs and the emergence of managed care organizations led to efforts to reduce the abuse over-ordering and misuse eg, ordering the right test for the wrong purpose or vice versa of these tests. The critical question facing physicians, however, is: What constitutes an unnecessary laboratory test? In the current climate of business-oriented medicine, the answer should not be: Any test for which reimbursement by a payer eg, Medicare is likely to be denied. What are the consequences of not ordering the test? How good is the test in discriminating between health versus disease?Link: https://killexams.com/exam-list/NI
- How are the test results interpreted? How will the test results influence patient management and outcome? The answers to these questions are critical to the optimal selection and cost-effective use of laboratory tests likely to benefit patient management. Nevertheless, it is widely accepted that the judicious use of laboratory tests, coupled with thoughtful interpretation of the results of these tests, can contribute significantly to diagnostic decision making and patient management. Reasons for Ordering a Laboratory Test There are 4 major legitimate reasons for ordering a laboratory test: 4 Diagnosis to rule in or rule out a diagnosis.Link: https://youtube.com/watch?v=yOSN3gcsyYA
- Monitoring eg, the effect of drug therapy. Screening eg, for congenital hypothyroidism via neonatal thyroxine testing. Research to understand the pathophysiology of a particular disease process. Approaches for Establishing a Diagnosis Based on Laboratory Test Results The principal approaches for establishing a diagnosis based on laboratory test results include: 4 Hypothesis deduction. Medical algorithms. Rifle versus shotgun approach. Example 1Hypothesis deduction approach to laboratory test ordering: A 4-year-old child presents to the emergency room ER with an upper respiratory tract infection URI , fever The clinician establishes a differential diagnosis of meningitis versus febrile seizures and deduces that the most appropriate laboratory tests to discriminate between these possibilities are the following tests performed on cerebrospinal fluid CSF from a spinal tap: White blood cell WBC and red blood cell RBC counts.Link: http://skaiventures.com/cgi-bin/content/view.php?q=001+rhetorica+ad+herennium+loeb+classical+library+pdf&id=a11f135d5940ff593e19836cbbb8a805

- What is the mean of X? Use the following information to answer the next four exercises. His batting average is 0. You decide to track his batting performance his next 20 at-bats. Define the random variable X in this experiment. Given this information, what number of hits do you predict Joe will get? What are the three major characteristics of a geometric experiment? You decide to conduct a geometric experiment by flipping a coin until it comes up heads. This takes five trials. Represent the outcomes of this trial, using H for heads and T for tails. You are conducting a geometric experiment by drawing cards from a normal card pack, with replacement, until you draw the Queen of Hearts. What is the domain of X for this experiment?Link: https://youtube.com/watch?v=gfR3n5UpBCY
- You conduct a survey of students to see how many books they purchased the previous semester, the total amount they paid for those books, the number they sold after the semester was over, and the amount of money they received for the books they sold. Which variables in this survey are discrete, and which are continuous? With continuous random variables, we never calculate the probability that X has a particular value, but always speak in terms of the probability that X has a value within a particular range.Link: http://holsmanhealthcare.com/Functional%20and%20Balance%20Tests%20for%20Geriatrics.pdf
- Why is this? What type of a distribution is this? The number of minutes that a patient waits at a medical clinic to see a doctor is represented by a uniform distribution between zero and 30 minutes, inclusive. If X equals the number of minutes a person waits, what is the distribution of X? Write the probability density function for this distribution. What is the mean and standard deviation for waiting time? What is the probability that a patient waits less than ten minutes? Describe this distribution in words. If the value of m for an exponential distribution is ten, what are the mean and standard deviation for the distribution? If the variable X has the standard normal distribution, express this symbolically. Use the following information for the next six exercises. What is the z-score for a height of inches? What is the z-score for a height of centimeters? Find the z-score for a height of centimeters and explain what that means In the context of the population.Link: https://dumpsfortest.com/DA-100-dumps-pdf
- What height corresponds to a z-score of 1. Using the empirical rule, we expect about 68 percent of the values in a normal distribution to lie within one standard deviation above or below the mean. What does this mean, in terms of a specific range of values, for this distribution? Using the empirical rule, about what percent of heights in this distribution do you expect to be between The distributor of lotto tickets claims that 20 percent of the tickets are winners. You draw a sample of tickets to test this proposition. Can you use the normal approximation to the binomial for your calculations?Link: https://nj01001706.schoolwires.net/cms/lib/NJ01001706/Centricity/Domain/288/Geometry%20Chapter%2011%20Worked%20Out%20Solutions.pdf
- Why or why not. What is the probability that your sample will have a mean greater than ? If the z-score for your sample result is —2. What does the central limit theorem state with regard to the distribution of sample means? The distribution of results from flipping a fair coin is uniform: heads and tails are equally likely on any flip, and over a large number of trials, you expect about the same number of heads and tails.Link: https://quizlet.com/42327749/251-vertebrate-origins-flash-cards/
- Yet if you conduct a study by flipping 30 coins and recording the number of heads, and repeat this times, the distribution of the mean number of heads will be approximately normal. How is this possible? The mean of a normally-distributed population is 50, and the standard deviation is four. If you draw samples of size 40 from this population, describe what you would expect to see in terms of the sampling distribution of the sample mean. X is a random variable with a mean of 25 and a standard deviation of two. Write the distribution for the sample mean of samples of size drawn from this population. Your friend is doing an experiment drawing samples of size 50 from a population with a mean of and a standard deviation of This sample size is large enough to allow use of the central limit theorem, so he says the standard deviation of the sampling distribution of sample means will also be Explain why this is wrong, and calculate the correct value.Link: https://samtec.com/products/gmi
- Use the following information to answer the next six exercises. What is the expected distribution of the sample means? One of your friends tries to convince you that the standard error of the mean should be 4. Explain what error your friend made. What is the z-score for a sample mean of 76? What is the z-score for a sample mean of What sample mean corresponds to a z-score of 1. If you decrease the sample size to 50, will the standard error of the mean be smaller or larger? What would be its value? Use the following information to answer the next two questions. We use the empirical rule to analyze data for samples of size 60 drawn from a population with a mean of 70 and a standard deviation of 9. What range of values would you expect to include 68 percent of the sample means?Link: https://onlinelibrary.wiley.com/doi/full/10.1111/cid.12912
- If you increased the sample size to , what range would you expect to contain 68 percent of the sample means, applying the empirical rule? How does the central limit theorem apply to sums of random variables? Explain how the rules applying the central limit theorem to sample means, and to sums of a random variable, are similar. If you repeatedly draw samples of size 50 from a population with a mean of 80 and a standard deviation of four, and calculate the sum of each sample, what is the expected distribution of these sums?Link: https://classmarker.com/online-test/start/?quiz=7vp5c241cc6d5228
- You draw one sample of size 40 from a population with a mean of and a standard deviation of seven. Compute the sum. What is the probability that the sum for your sample will be less than 5,? If you drew samples of this size repeatedly, computing the sum each time, what range of values would you expect to contain 95 percent of the sample sums? What value is one standard deviation below the mean? What value corresponds to a z-score of 2. What does the law of large numbers say about the relationship between the sample mean and the population mean? Applying the law of large numbers, which sample mean would expect to be closer to the population mean, a sample of size ten or a sample of size ?Link: https://examplaza.com/2020-2021-neco-yoruba-answers
- This gives all students an equal chance to prepare and should improve the quality of the answers — and the quality of learning — without making the exam any easier. Some of the principle advantages to oral exams are that they provide nearly immediate feedback and so allow the student to learn as they are tested. There are two main drawbacks to oral exams: the amount of time required and the problem of record-keeping.Link: https://questions.examside.com/past-years/gate/question/what-value-would-the-following-function-return-for-the-input-gate-cse-1998-marks-2-ryynitl3go6kwk6l.htm
- Computational Computational questions require that students perform calculations in order to solve for an answer. Effective computational questions should: Be solvable using knowledge of the key concepts and techniques from the course. Before the exam solve them yourself or get a teaching assistant to attempt the questions. Indicate the mark breakdown to reinforce the expectations developed in in-class examples for the amount of detail, etc.Link: https://wordpress.org/plugins/tutor/
- To prepare students to do computational questions on exams, make sure to describe and model in class the correct format for the calculations and answer including: How students should report their assumptions and justify their choices The units and degree of precision expected in the answer Suggestion: Have students divide their answer sheets into two columns: calculations in one, and a list of assumptions, description of process and justification of choices in the other. This ensures that the marker can distinguish between a simple mathematical mistake and a profound conceptual error and give feedback accordingly. Selected references: Cunningham, G.

- Proper equipment selection and use. Proper labeling procedures and completion of laboratory requisitions. Order of draw for multiple tube phlebotomy. Preferred venous access sites, and factors to consider in site selection, and ability to differentiate between the feel of a vein, tendon and artery. Patient care following completion of venipuncture. Safety and infection control procedures. Quality assurance issues. Identify the additive, additive function, volume, and specimen considerations to be followed for each of the various color coded tubes. List six areas to be avoided when performing venipuncture and the reasons for the restrictions. Summarize the problems that may be encountered in accessing a vein, including the procedure to follow when a specimen is not obtained.Link: https://cc.gatech.edu/~rpeng/CS3510_F17/Homeworks/HW1Sol.pdf
- List several effects of exercise, posture, and tourniquet application upon laboratory values. Each phlebotomist generally establishes a routine that is comfortable for her or him. Phlebotomists are considered to have occupational exposure to blood borne pathogens. The performance of routine vascular access procedures by skilled phlebotomists requires, at a minimum, the use of gloves to prevent contact with blood. Laboratory coats or work smocks are not typically needed as personal protective equipment during routine venipuncture, but an employer must assess the workplace to determine whether certain tasks, workplace situations, or employee skill levels may result in an employee's need for laboratory coats or other personal protective equipment to prevent contact with blood.Link: https://odin.cse.buffalo.edu/teaching/cse-562/exams/2018-final.pdf
- As part of presenting a professional appearance, an institutional dress code may include wearing of a laboratory coat or smock. Several essential steps are required for every successful collection procedure: Patient comfort. Is the seating comfortable and has the patient been seated for at least 5 minutes to avoid being rushed or confused? Carry out hand hygiene before and after each patient procedure, before putting on and after removing gloves. Identify the patient using two different identifiers, asking open ended questions such as, "What is your name?Link: https://premiumexam.net/which-type-of-drive-is-typically-installed-in-a-5-25-inch-13-34-cm-bay/
- Check the requisition form for requested tests, patient information, and any special requirements. Label the collection tubes at the bedside or drawing area. Select a suitable site for venipuncture. Prepare the equipment, the patient and the puncture site. Perform the venipuncture, collecting the sample s in the appropriate container s. Recognize complications associated with the phlebotomy procedure. Promptly send the specimens with the requisition to the laboratory. This requisition form must contain the proper information in order to process the specimen. The essential elements of the requisition form are: Patient's surname, first name, and middle initial. Patient's ID number. Patient's date of birth and sex. Requesting physician's complete name. Source of specimen. This information must be given when requesting microbiology, cytology, fluid analysis, or other testing where analysis and reporting is site specific.Link: https://hrci.org/our-programs/our-certifications/overview
- Date and time of collection. Initials of phlebotomist. The key elements in labeling are: Patient's surname, first and middle. Date, time and initials of the phlebotomist must be on the label of EACH tube. Automated systems may include labels with bar codes. The rubber stoppers are color coded according to the additive that the tube contains. Various sizes are available. Blood should NEVER be poured from one tube to another since the tubes can have different additives or coatings see illustrations at end. Needles - The gauge number indicates the bore size: the larger the gauge number, the smaller the needle bore. Needles are available for evacuated systems and for use with a syringe, single draw or butterfly system.Link: https://youtube.com/watch?v=fcxKtlF45-4
- Tourniquet - Wipe off with alcohol and replace frequently. Gauze sponges - for application on the site from which the needle is withdrawn. Gloves - can be made of latex, rubber, vinyl, etc. Syringes - may be used in place of the evacuated collection tube for special circumstances. The recommended order of draw for plastic collection tubes is: First - blood culture bottle or tube yellow or yellow-black top Second - coagulation tube light blue top. If just a routine coagulation assay is the only test ordered, then a single light blue top tube may be drawn. If there is a concern regarding contamination by tissue fluids or thromboplastins, then one may draw a non-additive tube first, and then the light blue top tube.Link: https://corporatefinanceinstitute.com/resources/careers/interviews/about-hirevue-interview/
