Duties of a Certified Nursing Assistant CNA
The duties of a certified nursing assistant (CNA) include a wide range of responsibilities depending where you work and in which state you reside. These tasks vary with the job and facility and also vary somewhat from state to state. There are many laws of responsibility and liability that cover the exact duties of a CNA.
As you go through your formal education and training you will learn more about the law of your state and how it applies to your role as a certified nursing assistant. Your first obligation will be the client or the patient. You will often be responsible for the daily management and routine of your patient. This is especially true for the care of elderly people in nursing home and extended care facilities.
Most likely your second obligation will be to carry out the mission, goals, and objectives of the facility where you are working. Many places today offer intense training and an orientation program to carefully go over the expectation of their workers.
Your third obligation will be to carry out the duties of a certified nursing assistant as you were trained and educated to do and perform. This becomes your major obligation and you will find it very rewarding and satisfying.
One of the specific responsibility of a CNA include making sure the rights of the patient are always protected. This includes the right of privacy, the right to be informed of their health care program and treatment, their right to accept or reject treatment, and the right to be included in their health care plan information.
Because nurses do not spend a lot of time in direct contact with the patient the certified nursing assistant becomes the "eyes and the ears" of the nurse. Your duties will include to keep close watch over your patient or client and be familiar with emergency responses in case of need. In most situations the duties of a certified nursing assistant also include the monitoring of vital signs for your client or patient.
Of course this will involve you taking temperature, respiration, pulse, blood pressure, and level of pain. These are common duties that you will perform everyday on all of your patients. Most likely your responsibilities will also include helping with the feeding process to ensure that patients are eating. You may also be assigned the task of bed-making, hair care, and bed-bath responsibilities.
There are many duties of a certified nursing assistant and the responsibility is enormous and challenging. The reward will also be exciting and very satisfying.

Being a Nurse - Its Benefits and an Overview of What They Do
The current financial crisis makes it difficult to survive for a lot of us. For the most part, we find ourselves overwhelmed by one financial problem after the other. As such, we couldn't help but ask ourselves what kind of career will give us a stable source of income and a better life for us or our families?
Well, you might be surprised that the answer to that question is more obvious that you think: being a nurse. At this time, nurses are one the most in-demand workers in the health industry. There are approximately 2.4 million job openings for nurses right now, and to fill this need, hospitals and the like are offering competitive salary, benefits, and compensation package.
There are a lot of opportunities for personal growth and development in nursing. Specialization in specific nursing fields is an alternative which nurses can take advantage of not just in hospitals, but even in medical clinics, outpatient centres, nursing care facilities, and geriatric facilities.
With a wide array of work places that offer career development, nurses would practically never run out jobs. Also, this kind of advantage makes nurses competent enough to work even in other parts of the globe.
Aside from the popularity of nurses nowadays, nursing is one of the very few careers which will never go passé. Like doctors, there will always be a need for nurses. Also, there are several types of job opportunities in the field of nursing. In the Unites States alone, there is currently a need for approximately 100,000 nurses, and experts say that this figure may triple over the years. With incentives like these, who could say no to such a promising career?
Registered Nurse (RN) - Background of their Duties and Responsibilities
The duties and responsibilities of a registered nurse can change from every state and institution. Laws on a RN's scope of practice vary in each state. Different institutions also have varying guidelines for the scope of practice of the nurses and medical professionals they handle. At times, these guidelines are even more restrictive than that of state laws.
To help an RN determine whether something is within the scope of their profession, some states have devised the following questions which RN's can ask themselves:
1. Is it allowed by the nurse practice act of the state you are working in?
2) Is the skill something you learned in your basic nursing education or in any additional training program you've attended, including clinical training?
3) Can you find the procedure in the policy manual of the institution you are working for?
4) Is the task in conformity to the "Prudent and Reasonable" standard for nursing?
If after asking these questions a nurse is still unsure whether a task is included in their scope of practice, he or she can get clarification from their state nursing board.
Evaluating a person's health and devising an appropriate health plan is one of main duties of an RN. Normally, RN's coordinate with other health care professionals in giving individuals under their supervision suitable health care and education.
However, as mentioned before, the regulations in each state differ. As such, it is wise to always consult the nursing laws in the state where a nurse is working to verify if a particular task is within a RN's scope of practice. A RN should also check the policy and guidelines of the institution they are working for, to ensure that what they are doing is within the areas of responsibility allowed by that institution.
LPN (Licensed Practical Nurse) - Playing an Important Role in the Healthcare Industry
A Licensed Practical Nurse (LPN) or Licensed Vocational Nurse in the state of Texas and California, assists RNs and give patients a more personal level of attention.
Although LPN's are normally supervised by physicians and RNs, their responsibilities increase as their gain more knowledge and experience.
Some LPNs already take on tasks such as taking vital signs, monitoring in and out volumes, turning patients to avoid bedsores, treating and/or dressing wounds, providing enemas and more.
LPNs also take care of simple duties like getting measurements (height, weight, temperature, blood pressure, pulse rate, etc.), giving alcohol rubs, assisting patients take care of their personal hygiene, and most of all, offering the patients a friendly face and a caring heart as they walk the road to recovery.
LPNs are the ones responsible for the day to day care of patients. They give patients a more intimate and hands on attention, which RNs are no longer able to provide due to their busy schedule.
In some states, LPNs are allowed to administer prescribed medicines and starting IVs. On other states however, such tasks are not part of their responsibilities. LPNs also need to spend time with the family of the patient and teach them how to take care of their loved one, especially once they continue their recuperation at home. The LPNs provide the patient's family with all the information they need to take care of the patient once they've been discharged.
Due to the variations of state regulations, it is hard to give a definite job description for a LPN. Some states even allow LPNs to assist with the delivery, care, and feeding of a newborn.
For the most part, the work of LPNs covers various fields of medicine and healthcare. As such, there are also LPNs who work in nursing homes, medical offices, or private homes.
Healthcare facilities like nursing homes certainly benefit from the services of LPNs, as they are able to asses residents, supervise nursing aides, and develop basic healthcare plans. In a doctor's clinic, a LPN takes care of setting appointments, filing medical records, and other administrative functions.
LPNs are very important to the smooth flow of the health care profession. RNs and NPs will definitely have a harder time with their jobs without LPNs.
Although the general scope of practice of LPNs is apparent, the extent of what they can perform will vary depending on their place of work.
As you think of starting a career in nursing, it is important to note that although doctors and administrators may be on top of the list, nurses and LPNs are definitely the heart and soul of the healthcare industry.

Why Laboratory Refrigerators Are So Different From the Domestic Version
Many people think that a lab refrigerator is just a larger version of the domestic refrigerator. But there is more to a lab freezer than what a novice knows. Lab refrigerators are specifically designed to store critical materials over extended periods of time. The temperatures of these refrigerators is maintained and kept constant at all times so that the many specimens and samples that are kept in it can be preserved in a stable environment.
There are mainly two types of lab refrigerators. One is called the chest freezer and the other called the upright freezer. The main difference between the two is the footprint space that they take. The upright refrigerator, in comparison to the chest refrigerators, has a far smaller footprint without having to compromise on the storage capacity.
Chest refrigerators are also more effective in cooling and maintaining the temperatures by retaining the cool air in a more efficient manner than the upright refrigerator. These chest refrigerators also have the capacity of recovering and going back to the original regulated temperature even when the door of the freezer is kept open for longer durations. However, the biggest advantage that upright refrigerators have over chest refrigerators is that the samples kept in them are much easier to locate.
Laboratory refrigerators work most efficiently when the temperature of the room in which they are kept is also regulated and maintained. Very high temperatures hamper the performance of the refrigerator, and therefore it is best to keep them in rooms which have a temperature going up to a maximum of 45 degrees C. However, in high room temperatures the pressure on the freezer compressor is higher. Allowing proper air circulation is very important so that the refrigerators keep functioning well.
Cramming the room with too many refrigerators will increase the heat emission from the refrigerators and increase the overall temperature of the room thereby putting pressure on the compressor. Lab refrigerators cannot be auto defrosted because this cycle normally destroys the biological samples as this method thaws and then re freezes the samples.
Laboratory refrigerators are designed bearing in mind that a number of volatile or flammable objects will be stored in them. At times specially designed refrigerators are used just for the purpose of storing these samples. Such refrigerators are CFC free, have compressors that are thematically sealed and have an insulation that is foamed in place. The design of these refrigerators also allows them to tolerate explosions.
Another very important aspect of the lab fridge is the alarm system. Most laboratory refrigerator manufacturing companies install an alarm in the refrigerator that is programmed to go off the moment there is a change in the temperature or if the door to the freezer has been left open. A number of refrigerators are also being manufactured with alarm systems, password protection and temperature graphs that allow 24X7 monitoring. Since the advent of the computer fridges can be specially designed keeping in mind its functionality and requirements, making life in the lab a whole lot easier.

Mattress Retail and Consumers Shopping For Sleep Face Off in Poker Challenge
The mattress retail professionals are facing off against the underdog shop for sleep consumers in a high stakes poker game to finally decide whether the "new" or the "used" option is the best. The professionals with their "steely" game faces and their fast dealing will attempt to break the bank of the novice shoppers. The seasoned bargain hunters will also attempt to ply their strategy against the professionals. The "buy in" is so cheap that it's hard to get a seat at the table.
Everyone wants in, but many of the participants had arrived well before the consumers. The hitchhikers and the stowaways took their places in this challenge months and even years ago. The dealers are sharper than the fastest ever seen in Las Vegas. They will attract you to the game with their deceptive ads, their low table antes, and their innocent appearances. The odds makers, after examining years of historical statistics, are favoring the "new" option, by a 40 to 1 margin. The totality of a defeat to the consumer, once seated in a game like this, will probably not be calculated or realized until the "bite" begins to blossom.
The hitchhikers and the stowaways, barely noticeable when seated at the low ante table, come to the surface soon after the consumer takes his "winnings" home. The bite of his loss is painless at first. It looks like the innocent bite of a mosquito, a flea, or a spider. Soon the welts get bigger; they begin to itch like a mosquito bite. A quick survey of the house reveals no flying nuisances. A few nights later, the victim and his spouse are covered with small to medium size welts that look like an allergic reaction. Maybe, it's scabies. Sarcoptes scabiei, commonly known as the human itch mite, burrows under the skin and sometimes leads to bacterial Staphylococcus infections. They have a worldwide distribution and can be transmitted from one person to another until the patients are treated and the mites and their eggs have been destroyed. Products used to kill them in an infected patient are only available by prescription. No over the counter products will do the job. Decontaminating the breeding ground is an even tougher task. How can they be removed from the house? The CDC suggests:
Bedding, clothing, and towels used by infested persons or their household, sexual, and close contacts (as defined above) anytime during the three days before treatment should be decontaminated by washing in hot water and drying in a hot dryer, by dry-cleaning, or by sealing in a plastic bag for at least 72 hours. Scabies mites generally do not survive more than 2 to 3 days away from human skin.
The visit to the doctor finds no burrowing pests under the skin. He suggests a real close examination of the mattress recently placed in the bedroom. "You may have a bed bug problem," he says.
The rush to examine the "new" mattress reveals the culprit. There they are! The tiny hitchhikers and stowaways are reddish in color. Cimex lectularius are all over the tape edge at the foot of the mattress. They are visible to the naked eye and are approximately 1/5 inch long. They hide during the day, so they not easily noticed. Their "fecal spots, egg cases, and shed skins" can oftentimes be sighted at the seams. The life cycle details, published in a UC Davis article, now inspire a fear of household contamination, though it is probably too late to do anything about it.
Bed bugs can go without feeding for 80 to 140 days. Older stages of nymphs can survive longer without feeding than younger ones, and adults have survived without food for as long as 550 days. A bed bug can take six times its weight in blood, and feeding can take 3 to 10 minutes. Adults live about 10 months, and there can be up to 3 to 4 generations of bed bugs per year.
Further reading reveals that the most effective technique for eliminating bed bugs is to hire a professional heating service that can heat the room to very high temperatures. Heating the room for two hours at 140 degrees F, or three hours at 130 degrees F "will kill most bed bugs and eggs." Other techniques involve insecticides, boric acid, diatomaceous earth, fumed silica, etc. Most of them need to be combined with frequent monitoring, as they are not totally effective. Meticulous laundering of bedding, high temperature drying, and thorough vacuuming are all necessary.
The game had an attractive "buy in" but the high stakes have broken the bank of the consumer. He has thrown his "new" mattress set out of the house. He has hauled it to the dump. He has decontaminated the house. He has paid the doctor bill and has also purchased a better vacuum cleaner. The costs have proven that the game was not worth the gamble. The "bite" of the consumer's loss will sting for a very long time. NO, Gamblers Anonymous will not be necessary. All the victim needs now is a fresh start in the shop for sleep, and a good clean game with a slightly higher "buy in."
Consumers, be careful where you "buy in." Consider the stakes of the challenge, and the skills of your opponent. You may not be able to survive the bite.
