1The Nursing Assistant inLong-Term Care1. Compare long-term care to otherhealthcare settingsWelcome to the world of health care. Healthcare happens in many places. Nursing assistantswork in many of these settings. In each settingsimilar tasks will be performed. However, eachsetting is also unique.This textbook will focus on long-term care.Long-term care (LTC) is given in long-term carefacilities (LTCF) for persons who need 24-hoursupervised nursing care. This type of care isgiven to people who need a high level of care forongoing conditions. The term “nursing homes”was once widely used to refer to these facilities.Now, however, they are often called long-termcare facilities, skilled nursing facilities, residential facilities, rehabilitation centers, or extendedcare facilities.People who live in long-term care facilities maybe disabled and/or elderly. They may arrive fromhospitals or other healthcare settings. Theirlength of stay (the number of days a personstays in a care facility) may be short, such asa few days or a few months, or longer than sixmonths. Some of these people will have a terminal illness. This means that the person is expected to die from the illness. Other people mayrecover and return to their homes or to otherfacilities or situations.Most conditions seen in long-term care arechronic. This means they last a long period oftime, even a lifetime. Chronic conditions includephysical disabilities, heart disease, stroke, anddementia. (You will learn more about these disorders and diseases in Chapters 4 and 5.)People who live in long-term care facilities areusually called “residents” because the facility iswhere they reside or live. These places are theirhomes for the duration of their stay.People who need long-term care will have different diagnoses, or medical conditions determined by a doctor. The stages of illnessesor diseases affect how sick people are and howmuch care they will need. The job of nursingassistants will also vary. This is due to each person’s different symptoms, abilities, and needs.Other types of healthcare settings include:Home health care is provided in a person’shome (Fig. 1-1). This type of care is also generally given to people who are older and are chronically ill but who are able to and wish to remainat home. Home care may also be needed when aperson is weak after a recent hospital stay. Homecare includes many of the services offered inother settings.Fig. 1-1. Home care is performed in a person’s home.1The Nursing Assistant in Long-Term Care1

The Nursing Assistant in Long-Term Care12Assisted living facilities provide some helpwith daily care, such as showers, meals, anddressing. Help with medications may also begiven. People who live in these facilities do notneed skilled, 24-hour care. Assisted living facilities allow more independent living in a homelike environment. An assisted living facility maybe attached to a long-term care facility, or it maystand alone.Subacute care can be given in a hospital or ina long-term care facility. Subacute care is givento people who have had an acute injury or illness or problem resulting from a disease. Thesepatients need treatment that requires more carethan some long-term care facilities can give andless care than acute illnesses require. The cost isusually less than a hospital but more than longterm care.Adult daycare is care given at a facility duringdaytime working hours. Generally, adult daycareis for people who need some help but are not seriously ill or disabled. Adult daycare centers givedifferent levels of care. Adult daycare can alsoprovide a break for spouses, family members,and friends.Outpatient care is usually given for less than24 hours. It is for people who have had treatments or surgery and need short-term skilledcare.Acute care is given in hospitals and ambulatory surgical centers. It is for people who havean immediate illness. People are admitted forshort stays for surgery or diseases. Acute care is24-hour skilled care for temporary, but serious,illnesses or injuries (Fig. 1-2). Skilled care ismedically necessary care given by a skilled nurseor therapist. This care is available 24 hours aday. It is ordered by a doctor, and involves atreatment plan.Rehabilitation is care given in facilities orhomes by a specialist. Physical, occupational,and speech therapists restore or improve function after an illness or injury. You will learnmore about rehabilitation and related care inChapter 9.Hospice care is given in facilities or homes forpeople who have six months or less to live. Hospice workers give physical and emotional careand comfort. They also support families. Youwill learn more about hospice care in Chapter 3.2. Describe a typical long-term carefacilityLong-term care facilities (LTCF) are businessesthat provide skilled nursing care 24 hours aday. These facilities may offer assisted livinghousing, dementia care, or subacute care. Somefacilities offer specialized care. Others care forall types of residents. The typical long-term carefacility offers personal care for all residents andfocused care for residents with special needs.Personal care includes bathing, skin, nail andhair care, and assistance with walking, eating,dressing, transferring, and toileting. All of thesedaily personal care tasks are called “activities ofdaily living,” or ADLs. Other common servicesoffered at LTCFs include the following:Fig. 1-2. Acute care is performed in hospitals for illnessesor injuries that require immediate care. Physical, occupational, and speech therapy Wound care

Care of different types of tubes and catheters(a thin tube inserted into the body that isused to drain fluids or inject fluids) Nutrition therapy Management of chronic diseases, such asAIDS, diabetes, chronic obstructive pulmonary disease (COPD), cancer, and congestiveheart failure (CHF)When specialized care is offered at long-termcare facilities, the employees must have specialtraining. Residents with similar needs may beplaced in units together. Non-profit companiesor for-profit companies can own long-term carefacilities.Residents’ RightsCulture ChangeSome long-term care facilities are adopting newermodels of care. These models promote meaningful environments with individualized approaches tocare. Culture change is a term given to the processof transforming services for elders so that they arebased on the values and practices of the personreceiving care. Culture change involves respectingboth elders and those working with them. Core values are choice, dignity, respect, self-determination,and purposeful living. To honor culture change, carefacilities may need to change organization practices, physical environments, and relationships at alllevels.

Explain Medicare and MedicaidThe Centers for Medicare & Medicaid Services(CMS), formerly the Health Care Finance Administration (HCFA), is a federal agency withinthe U.S. Department of Health and Human Services (Fig. 1-3). CMS runs two national healthcare programs, Medicare and Medicaid. Theyboth help pay for health care and health insurance for millions of Americans. CMS has manyother responsibilities as well.Fig. 1-3. The CMS website’s address is cms.hhs.gov.Medicare is a health insurance program thatwas established in 1965 for people aged 65 orolder. It also covers people of any age with permanent kidney failure or certain disabilities.Medicare has four parts. Part A helps pay forcare in a hospital or skilled nursing facility or forcare from a home health agency or hospice. PartB helps pay for doctor services and other medical services and equipment. Part C allows privatehealth insurance companies to provide Medicarebenefits. Part D helps pay for medications prescribed for treatment. Medicare will only pay forcare it determines to be medically necessary.Medicaid is a medical assistance program forlow-income people. It is funded by both the federal government and each state. Eligibility is determined by income and special circumstances.People must qualify for this program.Medicare and Medicaid pay long-term care facilities a fixed amount for services. This amount isbased on the resident’s needs upon admission.4. Describe the role of the nursingassistantNursing assistants can have many different titles. “Nurse aide,” “certified nurse aide,” “patientcare technician” and “certified nursing assistant” are some examples. This textbook will usethe term “nursing assistant.”1The Nursing Assistant in Long-Term Care3

The Nursing Assistant in Long-Term Care14Nursing assistants (NAs) perform assigned nursing tasks, such as taking a resident’s temperature. Nursing assistants also provide personalcare, such as bathing residents, helping them eatand drink, and helping with hair care (Fig. 1-4).Promoting independence and self-care are othervery important tasks that nursing assistantsdo. Other nursing assistant duties include thefollowing:Nursing assistants spend more time with residents than any other care team member. Theyact as the “eyes and ears” of the team. Observingchanges in a resident’s condition and reportingthese changes is a very important role of theNA. Residents’ care can be revised or updatedas conditions change. Another role of the NA iswriting down important information about theresident (Fig. 1-5). This is called charting.Fig. 1-4. Encouraging residents to drink often will be animportant part of your job. Helping residents with toileting needs Assisting residents to move around safely Keeping residents’ living areas neat andclean Caring for supplies and equipment Helping residents dress Making beds Giving backrubs Helping residents with mouth careNursing assistants are generally not allowed togive medications; nurses are responsible for giving medications. Some states allow nursing assistants to work with medications after receivingspecial training. Examples of other tasks thatnursing assistants are not allowed to do are inserting/removing tubes, changing sterile dressings, and giving tube feedings.Fig. 1-5. Observing carefully and reporting accurately aresome of the most important duties you will have.Nursing assistants are part of a team of healthprofessionals. The team includes doctors,nurses, social workers, therapists, dietitians,and specialists. The resident and resident’sfamily are part of the team. Everyone, including the resident, works closely together to meetgoals. Goals include helping residents to recoverfrom illnesses or to do as much as possible forthemselves.Residents’ RightsResponsibility for ResidentsAll residents are the responsibility of each nursingassistant. You will receive assignments to completetasks, care, and paperwork for specific residents. Ifyou see a resident who needs help, even if he or sheis not on your assignment sheet, provide the neededcare.

5. Describe the care team and the chainof commandResidents will have different needs and problems. Healthcare professionals with differentkinds of education and experience will help carefor them (Fig. 1-6). This group is known as the“care team.” Members of the care team includethe following:Fig. 1-6. The care team is made up of many differenthealthcare professionals.The RN also writes and develops care plans. Acare plan is created for each resident. It helpsthe resident achieve his or her goals. The resident assists with developing the care plan. Thecare plan outlines the steps and tasks the careteam must perform. It states how often thesetasks should be performed and specifies howthey should be carried out.Licensed Practical Nurse (LPN) or Licensed Vocational Nurse (LVN). A licensed practical nurseor licensed vocational nurse is a licensed professional who has completed one to two years ofeducation. An LPN/LVN gives medications andtreatments. LPNs may also supervise nursing assistants’ daily care of residents.Physician or Doctor (MD or DO). A doctor’s jobis to diagnose disease or disability and prescribetreatment. Doctors have graduated from fouryear medical schools after receiving bachelor’sdegrees. Many doctors also take specializedtraining programs after medical school (Fig.1-7). (“DO” stands for “doctor of osteopathicmedicine.”)Nursing Assistant (NA) or Certified Nursing Assistant (CNA). The nursing assistant (NA) performs assigned tasks, such as taking vital signs.NAs also provide routine personal care, suchas bathing residents and helping with toileting.Nursing assistants must have at least 75 hours oftraining, and, in many states, training exceeds100 hours.Registered Nurse (RN). A registered nurse is alicensed professional who has completed two tofour years of education. RNs have diplomas orcollege degrees. They have passed a licensingexam given by the state board of nursing. Registered nurses may have additional academic degrees or education in special areas. In long-termcare, an RN coordinates, manages, and providesskilled nursing care. This includes giving special treatments and medication as prescribed bya doctor. A registered nurse also assigns tasksand supervises daily care of residents by nursingassistants.Fig. 1-7. Doctors diagnose disease and prescribetreatment.1The Nursing Assistant in Long-Term Care5

The Nursing Assistant in Long-Term Care16Physical Therapist (PT). A physical therapistevaluates a person and develops a treatmentplan. Goals are to increase movement, improvecirculation, promote healing, reduce pain, prevent disability, and regain or maintain mobility.A PT gives therapy in the form of heat, cold,massage, ultrasound, electricity, and exercise tomuscles, bones, and joints. For example, a PThelps a person to safely use a walker, cane, orwheelchair (Fig. 1-8). Physical therapist education programs are offered at two degree levels:doctoral and master’s. Entrance into these programs usually requires an undergraduate degree. Master’s degree programs usually last twoyears. Doctoral degree programs last three years.PTs have to pass national and state licensureexams before they can practice.Occupational Therapist (OT). An occupationaltherapist helps residents learn to compensate fordisabilities. An OT helps residents perform activities of daily living (ADLs). This often involvesequipment called assistive or adaptive devices.For example, an OT can teach a person to usea special fork to feed himself. The occupationaltherapist observes a resident’s needs and plansa treatment program. OTs generally have an undergraduate degree before being admitted to adoctoral or master’s program. OTs have to passa national certification examination and mostmust be licensed within their state.Speech-Language Pathologist (SLP). A speechlanguage pathologist helps with speech andswallowing problems. An SLP identifies communication disorders, addresses factors involvedin recovery, and develops a plan of care to meetrecovery goals. An SLP teaches exercises tohelp the resident improve or overcome speechproblems. For example, after a stroke, a personmay not be able to speak or speak clearly. AnSLP may use a picture board to help the personcommunicate thirst or pain. An SLP also evaluates a person’s ability to swallow food and drink.Speech-language pathologists are generally required to have a master’s degree in speech-language pathology. Most states require that SLPsbe licensed or certified to work.Registered Dietitian (RD). A registered dietitiancreates diets for residents with special needs.Special diets can improve health and help manage illness. RDs may supervise the preparation and service of food and educate others onhealthy nutritional habits. Registered dietitianshave completed a bachelor’s degree and may alsohave a master’s degree. They may also have completed postgraduate work. Most states requirethat RDs be licensed or certified.Fig. 1-8. A physical therapist will help restore specificabilities.Medical Social Worker (MSW). A medical socialworker determines residents’ needs and helpsget them support services, such as counseling.

He or she may help residents obtain clothingand personal items if the family is not involvedor does not visit often. A medical social workermay book appointments and transportation.Generally, MSWs hold a master’s degree in social work.Activities Director. The activities director plansactivities for residents to help them socializeand stay active. These activities are meant toimprove and maintain residents’ well-being andto prevent further complications from illness ordisability. An activities director may have a bachelor’s degree, associate’s degree, or qualifyingwork experience. An activities director may becalled a “recreational therapist” depending uponeducation and experience.Resident and Resident’s Family. The residentis an important member of the care team. Theresident has the right to make decisions abouthis or her own care. The resident helps plan careand makes choices. The resident’s family mayalso be involved in these decisions. The familyis a great source of information. They know theresident’s personal preferences, history, diet,rituals, and routines.Residents’ RightsResident as Member of Care TeamAll members of the care team should focus on theresident. The team revolves around the resident andhis or her condition, treatment, and progress. Without the resident, there is no team.As a nursing assistant, you will be carryingout instructions given to you by a nurse. Thenurse is acting on the instructions of a doctoror other member of the care team. This is calledthe chain of command. It describes the line ofauthority and helps to make sure that your residents get proper health care. The chain of command also protects you and your employer fromliability. Liability is a legal term. It means thatsomeone can be held responsible for harmingsomeone else. For example, imagine that something you do for a resident harms him. However,what you did was in the care plan and was doneaccording to policy and procedure. Then youmay not be liable, or responsible, for hurting theresident. However, if you do something not inthe care plan that harms a resident, you couldbe held responsible. That is why it is importantto follow instructions in the care plan and knowthe chain of command (Fig. 1-9).Fig. 1-9. The chain of command describes the line of authority and helps ensure that the resident receives propercare.Nursing assistants must understan
