Uncertainties in Measuring Devices All measured quantities have uncertainties associated with them. The purpose of error analysis is to determine how such uncertainties influence the interpretation of the experimental results 1. Systematic Error - Results from consistent bias in observation (ie. Instrument-calibration error, natural errors or personal error). - Can be eliminated by pre-calibrating against a known, trusted standard. - Affects accuracy 2. Random Errors - Results from fluctuations in the readings of a measurement apparatus, experimenter's interpretation of the instrumental reading or randomly changing conditions (weather, humidity, etc.). - Can be reduced by averaging multiple measurements. - Unbiased - Affects precision

Uncertainties in Measuring Devices General rule of thumb used to determine the uncertainty in a single measurement when using a scale or digital measuring device. 1. Uncertainty in a Scale Measuring Device is equal to the smallest increment divided by 2.

2. Uncertainty in a Digital Measuring Device is equal to the smallest increment.

In general, any measurement can be stated in the following preferred form:

The measured value is just an estimate and thus it cannot be more precise than the uncertainty of the device. (i.e. The number of decimal places for the measured value must match the number of decimal places for the uncertainty, and in multiples of the uncertainty)” Example: The smallest increment in a meter rule (scale measuring device) is 0.1 cm. Following the general rule of thumb to determine the uncertainty in a scale measuring device, it would therefore be half of the smallest increment (∆ l = 0.1/2 = 0.05 cm). The uncertainty of a meter rule is ± 0.05 cm, thus for the length measured, l = 31.225 ± 0.05 cm (incorrect) l = 31.23 ± 0.05 cm (incorrect) l = 31.25 ± 0.05 cm (correct)

Timeless

...Bryce Parker Mrs. Smith English 103-5008 2/18/2016 Timeless What if you could stop time, what would you do? Would you read more books, catch up on television shows, explore the world, contemplate the existence of life or perhaps be deviant? Two groups of people who, I think, would like to experience timelessness are artists and gamers, of which I am both. Not only for the practical reasons of getting things done, but for the quality of the experience each work of art or video game can give. I have a considerable library of games across multiple systems. However, I don't have nearly enough time to play them all, especially in a world where newer games are coming out each day. I have thought of a number of times I wish I had a device like the “Hyperbolic Time Chamber” from the anime series Dragon Ball; which would allow the one that entered it to experience a whole years’ time within the span of a single day. Granted the characters of the series used it to train themselves to fight their newest threat. My purpose would be different, it would give me the time to get though the games I either; found boring at the time, something new came out or have yet to play. Another reason, is to experience full immersion. To be totally entranced within the game, where the world around seems to disappear and the player feels a part of the game; as if they are standing next to the player controlled character or even are the character. Something similar I can compare it to is; when...

Jacintha Saldanha Case Study

...Question 1 King Edward VII’s Hospital Sister Agnes, established in 1899 with over a century’s worth of history brags about their top notch facilities, professional health consultants and nursing staff, zero occurrence of hospital-acquired MRSA infections and of course, its connection with the royal family (Standards 2013). However, the hospital came face to face with a major crisis when Mel Greig and Michael Christian, hosts of commercial radio station 2Day FM made a prank call to acquire confidential information of one of its patron at the time, Duchess of Cambridge, Kate Middleton. The suicide of Jacintha Saldanha surfaced three days after being the first person to receive the hoax phone call before passing it to the duchess’ private nurse. This essay aims to highlight the ethical implications involved in this case study, the PR strategies taken by the radio station and whether the actions taken are appropriate in regards to the death of the British nurse. When the Jacintha’s case of suicide arose, the ultimate question was: Why did she turn to suicide? Despite previous records of Jacintha’s suicide attempts (Taher 2012), it was reported that she had no signs of mental frailness at the time of her work shift before she received the prank call (Sykes 2012). While it remains unclear if the hoax call drove Jacintha suicidal, it may have acted as a catalyst (Baker 2012) since a note containing expression of anger addressed to the two radio hosts was found after Jacintha’s death...

...situation that prevails on our planet all the time and it does not make the headlines (Singer 160).” Yes, the factors listed are tough to combat; therefore, the issue of poverty should be taken more seriously. The constant debate between the rich and the poor are leaving many nauseated on an ethical roller coaster. Much of the Nation and the World are succumbing to poverty like a deadly plague devouring everything in sight. Poverty is a very serious problem; therefore, steps should be taken immediately to do more than what's being done. One necessary and extremely important step is to address some of the causes. When trying to uncover some causes of something of this magnitude, many factors need to be considered. In his book Practical Ethics, Peter Singer addresses the issue of Relative...

Aristotle: the Life Well Lived

...happiness, according to Aristotle is through reason. Aristotle starts off by saying that what makes humans unique from other animals is our ability to reason. It is through reason that we can become more like the “Gods” and come closer to living Aristotle’s view of the good life. Aristotle separates reason into two distinct categories: practical reason and theoretical reason. Practical reason can be thought of as the ability, through contemplation, to decide what one ought to do. Theoretical reason, on the other hand, can be viewed as reasoning that is directed at answering questions that are, coincidentally enough, theoretical. By theoretical I mean questions that are concerned with explaining and predicting what is going on around us. Going back to Aristotle’s assertion that reason is what separates us from lower beings, we can see that he is probably referring more to theoretical reason as opposed to practical reason. Any animal can exercise practical reason in determining what to do to survive, but can an animal reason theoretically? Aristotle says no and that is what separates human beings from animals. It is through reason, both practical and theoretical, that we develop virtue. According to Aristotle, virtue is the next step towards eudaimonia and it is developed through the exercise of reason. Just like with reason, Aristotle separates virtue into two categories. The first form of virtue is moral virtue. Moral virtue is excellence in...

The Attitudes and Barriers of Nurses Towards Pressure Ulcers in Long Term Care Facilities That Hinders Prevention & Treatment

...avoidable health care incidents) (Agency for Healthcare Research and Quality [AHRQ], 2012). Since 2008, the Centers for Medicare & Medicaid Services no longer reimburse providers for treatment of facility acquired Stage III or Stage IV PUs. Populations at risk for PU development include older adults, patients with dementia, and any person with conditions of immobility (Ratliff, Tomaselli, & The Guideline Task Force, 2010). Because an older adult is more likely than a younger person to have impaired mobility and co-morbid health conditions, elders are especially vulnerable for PU development. This is of particular concern given the large population of these individuals in our nursing home facilities. In 1992, the AHRQ developed early guidelines for preventing pressure ulcers. In general, prevention guidelines focus on reducing the amount and time of pressure and shear through pressure-redistribution surfaces and frequent repositioning while providing nutritional support when needed, and protecting the skin from dryness and moisture (NPUAP/ EPUAP, 2009). With clear guidelines available, why do some nurses provide adequate PU prevention while other nurses do not? Why are interventions not performed...

Medical Ethics

...the outcome should remain the same to avoid ethical and legal issues. This paper will review the case study to help resolve the problem, the ethics involved, and the medical responsibility to refilling a prescription without provider authorization. Qualified Medical Training Understanding the definitions of a licensed practical nurse, LPN, and a medical assistant, MA is the first step to making a factual conclusion for this case study. Support staff to the provider cannot make decisions about medication refills for patients without a direct order from the provider. This action is outside the scope of practice for an LPN or MA. Licensed Practical Nurse An LPN is a role in support of the nurse or RN, a registered Nurse usually in a skilled nursing setting such as a hospital or long-term care facility. As defined by the National Federation of Licensed Practical Nurses, NFLPN, an LPN “means the performance for compensation of authorized acts of nursing which utilize specialized knowledge and skills and which meet the health needs of people in a variety of settings under the direction of qualified health professionals” (National Federation of Licensed Practical Nurses, 2003).

Ethic Case Study

...important that those who work in the medical field know their scope of practice and keep within their professions guidelines. The following case study will discuss an issue a medical assistant/LPN has encountered during his shift at Dr. Williams’s office and why the assistant must act under his scope of practice. Case: Jerry McCall is Dr. Williams’s office assistant. He has received professional training as both a medical assistant and a LPN. He is handling all the phone calls while the receptionist is at lunch. A patient calls and says he must have a prescription refill for Valium, an antidepressant medication, called in right away to his pharmacy, since he is leaving for the airport in thirty minutes. He says that Dr. Williams is a personal friend and always gives him a small supply of Valium when he has to fly. No one except Jerry is in the office at this time. 1) Dose Jerry’s medical training qualify him to issue this refill order? Why or why not? No, Jerry’s medical training does not qualify him to issue refills on the patient’s Valium order. Jerry McCall is both a medical assistant and an LPN (license practical nurse) neither certificate nor license grants the ability to write prescriptions. Medical assistants are unlicensed health care personnel that can only preform non-invasive technical support under the supervision of a licensed physician. A practical nurse also referred to as a licensed vocational nurse, typically works beneath the supervision of a registered...

Ethics Case Study

...Ethics Case Study Sandra Childers HCS/335 January 16, 2012 Patricia Tobin. PhD, LCSW Ethics Case Study This paper discusses the dilemma of Jerry McCall. Jerry, office assistant of Dr. Williams, is a trained medical assistant and Licensed Practical Nurse (LPN). While covering the front desk while the receptionist was out to lunch, a patient and friend of Dr. Williams calls requesting a refill order for Valium. The friend is taking a trip by plane and takes the Valium when he flies. There are questions that arise from this scenario. Is Jerry qualified to fulfill this request? If the refill was for a different medication such as blood pressure medication would it make a difference? What are the legal ramifications should there be any harmful reactions? Does the doctrine of respondeat superior protect Jerry from any lawsuits? The answers to these questions are discussed within this paper. As a medical assistant Jerry McCall is trained to perform administrative and medical duties to maintain the smooth operation of the healthcare facility. He reports to the office manager and the physician, as he goes about performing his duties. Medical assistants are not physician’s assistants and do not have the training that a physician’s assistant has to examine, diagnose, and treat patients. As a medical assistant the administrative duties include updating and filing medical records, complete insurance claim forms, set up hospital admissions and lab appointments. When acting...

Ethics Case Study Paper

...Ethics Case Study – Jerry McCall University of Phoenix Ethics Case Study In health care today, there is sometimes a lax attitude regarding rules and regulations. Some allied health professionals may be tempted to inappropriately use their position because of a personal feeling of empowerment. There are always ethical and legal issues that influence outcomes and this care is just another example of the difficulties that allied health professionals face every day. Jerry is trained as a Licensed Practical Nurse (LPN) and currently working as a medical assistant. Jerry’s training allows him to provide general assessments, administer medications, and provide treatments. As an LPN, he is able to administer oral medications, as well as some injectable medications. Also, as a medical assistant, Jerry is also responsible for varying levels of clerical work, which may include the writing of scripts. This is more of a common practice today because of electronic prescription software. However, all prescriptions must be originated by a licensed physician and must undersigned by this same provider. Even though this patient is a personal friend of Dr. Williams, the same prescription standard needs to apply. Jerry would need to contact the physician to obtain a verbal order, which he needs to document appropriately before he can give the patient the script. Whether the fact that the medication is for fear of flying or if it is a critically needed medication like anti-hypertensive’s...

Nursing Informative Essay

...Nursing Informative Essay Imagine just for a minute being in a hospital. Have you ever wondered who is always taking care of different patients almost at the same time? Or how it is possible that medicine is so advanced compared to years before? I have the answer. The nurse is the person in charge of taking care of patients, and medicine is so advanced thanks to the technology we have nowadays. I chose to be a Registered Nurse (RN), but I know is not an easy job because they have to perform different job duties. Not everyone can become a nurse, in fact, to be one, you need some requisites first. Afterward, medicine has become improved because of the advances we have on technology. When people choose Registered Nursed (R.N.) as their career they have to perform various job obligations. According to a website called “Monster” registered nurses have to “provide direct patient care and report any changes in patient status to the doctor treating the patient”. The nurse also “needs to keep in contact with the patient to let the patient know he is in good hands and good care”. In addition to that, the doctor always “needs to be informed about any change in the patient’s health” so he knows what medicines give the patient to become healthy again. Additionally, the same website also addresses that “they also need to update the condition of the patient to their family members and about the trainings, medicines and precautions that the patient needs to take as per plan of care...

Lpn Career

...License Practical Nursing Introduction (paragraph 1)--License Practical Nursing is a career field that I always had an interest in, but I just never put a title to the interest. I have been working in this career path for 8 years now as a personal care aide for a home care agency. I have had the pleasure of being on the physical, side working directly with the patient, and administrative side, maintaining the office and clerical information. Paragraph 2-- When I first started into this career path I had all kinds of emotional, squeamish, and frightening obstacles that I had to overcome. In this career path, to be awesome at what you do, there is no room for being squeamish or frighten by the things that come along with it. You must always put the best on the outside. You are there to take care of the sick and that means that the sick isn't always a tolerable sight. The skills of an LPN goes far beyond education. A nurse must be compassionate, observant, firm but fair, and most of all willing to the support for the patient. These skill are innate, they cannot be taught but developed from within. While LPNs should possess a compassionate nature, they sometimes need to be thick-skinned when it comes to occasional unkind treatment from others. ("Licensed Practical Nurses."Ferguson's Career Guidance Center) A care provider whitout a heart is a poor care provider. As an LPN you are responsible for makings sure that the patient receives the proper care that is laid out by the Physician...
