Outline the phlebotomist’s responsibilities as a member of the health care team
represent the laboratory and the health care center, they are in contact with the patient, and they perform tasks that are critical to the patient’s diagnosis and care
traditional role of the phlebotomist in a hospital is only one job: to collect blood samples
centralized: sample collection where the phlebotomist is part of the laboratory team and is dispatched to hospital units to collect blood samples
often results in times of no work and other times of more work than can be done in a short time
works well until there are a large number patients to draw and the work cannot all be completed by 0700
decentralized: sample collection where all members of the health care team share the responsibility to collect blood samples
difficult for a hospital to hire people to come in at 0430 to just draw and then go home
everyone who has contact with the patient needs to become multiskilled
hybrid phlebotomy: blend of centralized and decentralized phlebotomy
used to reduce the errors of decentralized phlebotomy
typically sends lab-based phlebotomists to the nursing units during the early morning collections and then keeps a limited number of phlebotomists available the rest of the date to help PCT with difficult collections
Describe what it means to be a professional as a phlebotomist
common sense i fear
Phlebotomists should conduct themselves with honesty and respect, maintain professional competence, and promote ethical behavior in the healthcare system.
Electroencephalography
record electrical activity of the brain
help locate and access the extent of brain injury or determine if there is any brain activity
electrocardiology
does electrocardiograms
performed in the patient’s room
radiology
x-ray lungs, broken bones, cardiac catheterization , CT scans, MRI, and ultrasound
each of these techniques has become a subspecialty of radiology that still looks into the body as teh traditional x-ray did but in much more detailed and sophisticated way
pharmacy
hospital pharmacy dispenses many types of therapeutic drugs that often are much more potent thatn a prescription taken at home
prescribed and monitored under controlled onditions while the patient is in the hospital
with results of blood samples, pharmacists can consult with the lab and the patient’s physician to provide the best treatment possible for the patient
physical therapy
works with patients who, due to disease or injury, are no longer able to function to their full physical capacity
therapy may involve rebuilding deteriorated muscles after a long illness or learning to function after an amputation
occupational therapy is related, works with patients to overcome their physical challenges so they can be productive again in their old job or function in a new job
speech therapy is another area related to physical therapy
patients who have difficulty speaking or who have lost the ability to speak because of a stroke or disease are retaught how to speak
nursing
provide direct patient care
laboratory
provide testing of patient samples
include a variety of locations including;
main laboratory, ambulatory care laboartory, stat laboartory, and surgery laboartory
environmental services
maintains a clean facility
administration
keeps ths hospital in compliance
food service
provides diets to patients
gastrointestinal (GI) laboratory
diagnoses gastrointestinal disorders
medical records
maintain patient records
respiratory therapy
provide therapy to evaluate lungs
administrative office
responds to telephone cells, handles specimen collection requests, and handle some specimens
phlebotmy (sample collection)
collects samples form patients and processes samples for testing or transport
Descrube the importance of communication and maintaining quality care with the laboartory and with other departments of the hospital
Effective communication within a laboratory and with other hospital departments is critical for maintaining high-quality patient care by ensuring accurate information is shared promptly, preventing errors, coordinating treatment plans, and ultimately leading to better patient outcomes; poor communication can result in delays, misinterpretations, and potential harm to patients.
List five patient rights and explain how these patient rights would affect a phlebotomist’s job
patient has the right to considerate and respectful care
It is important for the phlebotomist to remain calm and to show consideration and concern for each patient.
patient has the right to and is encouraged to obtain from physicians and other direct caregivers relevant, current, and understandable information concerning diagnosis, treatment, and prognosis
except in emergencies whent he patient lacks descision-making capacity and teh need for treatment is urgent, the pateitn is entitled to the opportunity to discuss and requent information related tot eh specific procedures and/or treatments, the risks involved, the possible length of recuperation, and teh medically reasonable alternatives and their accompanying risks and benefits
patients have the right to know the identity of physicians, nurses, and other involve fin their care as well as when those involved are students, residents, or other trainees
patient also has the right to know the immediate and long-term financial implications of treatment choices, insofar as they are known
If questions are asked during the phlebotomy procedure, simply state that the physician has ordered blood to be drawn for testing and refer the patient to the physician. The phlebotomist may question the need for the test to be drawn or realize there was an error on a previous sample, and now the patient must be redrawn. Questions and concerns should not be discussed with the patient but with the phlebotomist’s supervisor or the nurse, outside the presence of the patient.
patient has the right to make decisions about the plan of care prior to and during teh course of treatment and to refuse a recommended treatment or plan or care to teh extent permitted by law and hospital policy and to be informed of the medical consequences of this action
The phlebotomist may need to explain briefly how the venipuncture is performed and that these are tests the physician has ordered.
patient has the right to have an advance directive (such as a living will, health care proxy, or durable power of attornery for health care) concerning treatment or designating a surrogate decision maker with teh exoectation htat the hospital will honor the intent of the directive to the extent permitted by law and hospital policy
patient ahs teh right to every consideration of privacy
Often the phlebotomist may be in the room at the time another procedure is being performed, the patient is completing personal hygiene, or the physician is examining the patient
patient has the right to expect that all communications and records pertaining to their care will be treated as confidential by the hospital, except in cases such as suspected abuse and public health hazards when reporting is permitted or required by law
patient has the right to expect that the shopital will emphasize the confidentiality of this information when it releases it to any other parties entitles to review information in these records
patient has the right to review the records pertaitning to their medical care and to habe the information explained or interpreted as necessary, exept when restricted by law
If the patient asks the phlebotomist to look at the chart, this request should be referred to the nurse or physician.
pateint ahs teh right to expect thatm within its capacity and politices, a hospital will make reasonable response to the request of a patient for appropriate and medically indicated care and services
The appropriate person to handle these requests is the nurse or physician. Often a patient may request a drink of water, aid in getting out of bed, and so on, from a phlebotomist. Refer these requests to the nursing staff, since the physician may have written specific orders denying the privilege because of upcoming surgery or other aspects related to that patient’s care.
patient has the right to ask to be informed of teh existence of business relationshupis among the hospital, educational institutions, other health care providers, or payors that may influence the patient’s treatment and care
A patient may request the phlebotomist’s name and title, and it is appropriate for you to give this information
patient has the right to concest or decline to participate in proposed research studies or human experimentation affecting care and treatment or requiring direct patient involvement and to have those studes fully explained prior to consent
patient has the right to expect reasonable continuity of care when appropriate and to be informed by physicians and other caregivers of abailable and realistic patient care options when hospital care is no longer appropriate
For the laboratory, this means that samples should be obtained and processed expeditiously to facilitate the care of the patient.
patiwent has the right to be informed of hospital policies and practices that relate to patient care, treatment, and responsibilities
patient has the right to be informed of abailable resources for resolving disputes, grievances, and conflicts, such as ethics committes, patient representatives, or other mechanisms available in the institution

explain the principle of and procedures for infection control
universal precautions - a principle to protect health care associates from infections as a result of exposure to body fluids
assumes that all blood and most body fluids are potentially infections
involved into a system called body substance isolation
assumes that each patient had the potential to spread disease through body substance
standard precautions - enhancement of universal precaustions and combine many of teh basic principles of universal preacutions with techniques from BSI
maintain that PPE and barrier controls must be worn for contact with all body fluids, whether or not blood is visible
goal is to reduce the risk of trasmission of microorganisms from both recognized and unrecognized sources of inception
five main points:
wash hands when changing gloves and between patietns
wear glvoes when likely to touch body substances, mucous membranes, or nonintact skin and during all blood drawing
wear protective cover when clothing is likely to be soiled
wear a mask and eye protection in addition to a protective body cocver when likely to be splashed with body substances
place intact needle/syringe and sharps in designated sharps containers; do not bend, break, or cut needles
describe how breaking the chain of infection can stop the spread of an infection
Breaking the chain of infection stops the spread of an infection by interrupting the steps that allow a microbe to pass from one person to another.
explain the differences in teh different types of transmission of infection
direct contact: physical transfer of infective material; from the source to susceptible host
indirect contact: transfer of infective material via an object, such as bed linens
droplet: droplets that travel 1 meter or less from the infected individual
vehicle: transfer of infective material through contaminated items, such as food
airborne: droplets that transfer on air currents, such as tuberculosis
vector: transmission by insects, such as malaria transmitted by mosquitoes
explain how the phlebotomist can control the transmission of infection
A phlebotomist can control the transmission of infection by consistently practicing good hand hygiene, wearing gloves for every patient interaction, using sterile, single-use equipment for each blood draw, properly disposing of sharps in designated containers, disinfecting work surfaces between patients, and following appropriate procedures for skin antisepsis when collecting blood samples; effectively breaking the chain of infection through these practices.
describe the proper handwashing technique and use of personal protective equipment
remove all rings, watches, and so on to prevent the jewelry from harboring microorganisms
have disposable towels ready or use an automatic towel dispenser so that you do not have to touch the towel dispenser
stand back from the sink so that you and your clothing do not touch the sink
turn on the water with the foot pedal or with a disposable tower if not foot controlled. The temp should be lukewarm.
wet hands under the running water. Be careful to not touch the sides of the sink
Apply soap, and lather well. The lather and scrubbing action will remove dirt and dead skin. Scrub between fingers and around fingernails. Continue to scrub for at least 20 seconds. Some facilities have a specific minimum time to scrub. Use a nail stick and a brush during the first handwashing of each day or when your hands become excessively soiled
Rinse hands with the water flowing downward off the fingertips. This will rinse the contaminated water off the fingertips and not onto the forearms
Complete the washing process again if this is the first handwashing of the day
Dry hands and wrists with the disposable towers
Turn off water with the disposable towels if the sink is not foot controlled
PPE used by the phlebotomist may include masks, goggles, face shields. gowns, and gloves
describe how the phlebotomist can reduce the spread of infection
A phlebotomist can significantly reduce the spread of infection by consistently practicing good hand hygiene, wearing gloves for every patient interaction, using sterile, single-use needles and equipment, properly disposing of sharps in designated biohazard containers, disinfecting work surfaces between patients, and following proper patient identification procedures
identify rules that promote safety of the individual and patient
Rules that promote patient safety include following infection control protocols, practicing good hand hygiene, and maintaining clean patient rooms.
Patient safety rules
Infection control: Wash hands or use hand sanitizer when entering and exiting a patient's room
Medication management: Take antibiotics as prescribed and report side effects
Cleanliness: Keep patient rooms clean
Fall prevention: Take precautions to prevent falls
Risk management: Identify and report potential risks
Communication: Communicate well with patients and staff
Learning: Learn from incidents and near misses
Leadership: Provide leadership and support staff
Involvement: Involve patients in their care
identify the differences in cleaning for phlebotomy and cleaning of hard surfaces
The key difference between cleaning for phlebotomy and cleaning hard surfaces lies in the specific focus on disinfecting living tissue (like a patient's vein) in phlebotomy using antiseptic solutions like alcohol swabs, while cleaning hard surfaces primarily involves removing dirt and debris with a general disinfectant, often requiring a longer contact time to kill microbes effectively; phlebotomy cleaning is more targeted and needs to be quick-drying to avoid patient discomfort, whereas hard surface cleaning can be more thorough and take longer depending on the surface and level of contamination.
identify policies and procedures for identifying laboratory safety
Laboratory safety policies and procedures for identifying hazards include: hazard identification through chemical safety data sheets (SDS), regular safety inspections, proper chemical labeling, employee training on hazard recognition, incident reporting, risk assessments for new experiments, and a system for reporting potential hazards; all aimed at proactively identifying and mitigating potential risks within the laboratory environment.
identify what “other potentially infectious material” is in healthcare
semen
vaginal secretions
cerebrospinal fluid
synovial fluid
pleural fluid
pericardial fluid
peritoneal fluid
amniotic fluic
saliva encountered during dental procedures
any body fluid that is visibly contaminated with blood
all body fluids in situations where it is difficult or impossible to differentiate between types of body fluids
any unfixed tissue or organ from human or nonhuman primate (living or dead)
HIV-containing cell or tissue cultures, organ cultures, cell medium, or other solututions
explain the purpose of material safety date sheets (MSDSs)
information sheets that must be kept on file and that indicate teh hazards of the chemicals used in each section of the lab
chemicals used in the lab must also contain labels indicating the identity of the chemical and showing warning appropriate for employee protection
explain the phlebotomist’s responsibility for fire safety and hazard identification
hazard identification
hazards can be identified on the container by a hazard emblem designed by teh National Fire Protection Association
contains a diamond shaped diagram further subdivided into smaller diamonds
health hazards are identified on teh left
flammability at the top,
reactivity on the right
bottom space is used to identify other hazards or to alert fire-fighting personnel to the possible hazard of using water
hazards are identified by color: blue for healthhazards, red for flammability, and yellow reactivity
diamonds are identified by # on a scale of 0 to 4 to indicate the severity of the hazard
fire safety
class A are used on class A fires and include foam, loaded-stream, and multipupose dry chemical extinguishers
includes those of ordinary combustible materials in teh lab, such as wood, plastics, and paper
class B inlude fires or flammable liquids and fases— that is, elements that require blockage of oxygen from teh fire to extinguish
extinguishers include carbon dixoide, dry chemical, foam, and loaded-stream
class C fires are energized electrical equipment
use of nonconductive media is needed to preven electrical shock when putting out such a fire
extinguishers include carbon dioxide and dry chemical extinguishers
class D includes fires of combustible and reactive metals such as sodium, potassium, magnesium, and lithium
poses special problems bc explosion and spreading can easily occur
most fire extinguishers found in the lab are of a unicersal ABC type
RACE
R = Rescue anyone in danger
A = Sound the alarm
C = Contain the fire by closing doors and/or windows
E = Extinguish/Evacuate. Extinguish the fire if possible. If the fire is too large to extinguish, start to evacuate anyone in the fire’s path
describe the procedure for clearing a chemical splash in the eye
Will need another person to help in holding the eye open and removing any contact lens that might be in the eye
should be flushed with water for 15 minutes
person must be evaluated for medical treatment by the emergency department or occupational health facility
explain the requirements for disposing of potentially infectious materials
(1) incineration,
most common method used to dispose of infectious waste in incineration
waste is burned to an ash, and then the ash is taken to the municipal disposal
kills any potentially infectious organisms and makes the items within the taste unusable
Healthcare institutions must rely on a commercial medical waste handler to dispose of the waste. will charge $$
(2) chemical treatment, and
alternative to incineration
consists of grinding or chopping the waste into small pellets and then treating the pellets with a disinfectant chemical to kill any infectious organisms
ended the waste unusable, while the disinfectant permits the waste to be sent to the municipal disposal site
(3) autoclave
can be used in small operations where only a small amount of waste is generated
waste material is placed in the autoflave
control tapes are placed on the biohazard bags to ensure adequacy in the sterilization
change color if the sterilization has reached the proper temp and pressure
once sealed, the autoclave is injected with steam under high pressure for 15 mins to cook the waste under pressure
describe precautionary measures and actions to be taken with accidental needle punctures
Wash the wound with soap and water.
If soap and water aren't available, use alcohol-based hand rubs or solutions.
If you are at work, notify your supervisor or occupational health and safety officer - you will need to fill out an accident report form.
explain teh appropriate response after an accidental biohazard exposure
wash exposed area with soap and water
report incident to supervisor immediately
exposed associate must be tested for HIV and HBV if consent is given
source individual’s blood is tested for HIV and HBV if consent is given
if source patient refuses testing, is HIV or HBS positive, or is in a high-risk category, associate may elect to recieve prophylactic treatment
Explain what preexamination errors can occur with a sample and how these errors can affect a patient’s outcome.
occur during any of the processes that it takes to collect the sample and get to the point in which testing of the sample occurs
most serious and potentially most dangerous preexamination error is improper patient ID
tourniquets - reduction of fluid volume results in hemoconcentration
inability to circulate lowers the pH and causes potassium to be forced out of the blood cells
also causes an elevation in calcium and magnesium
exercise and posture- exercise will change cell permeability, causing an increase in various analytes. hemoglobin will increase with exercise
incorrect volume of blood in the tube
fasting and timed samples - fasting samples after a 10- to 12- hour fast will give the best results for certain tests that are influenced by food intake
timed samples - timed samples are collected for those analytes that follow diurnal or circadian rhythms
hemolysis with syringe draws
cleansing the venipuncture site with betadine or iodine solutions
can cause increase potassium, phosphorous, and uric acid
incorrect order of draw
the order of draw for evacuated tubes will cause a carryover of additive from one tube to the next, resulting in compromised test results
Explain how exercise and stress can affect laboratory results.
exercise and posture
vigorous exercise can affect the result of testing
patent’s cell permeability will change if they have just completed vigorous exercise
causes an increase in concentration of creatine kinase (CK), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), bilirubin, creatinine, and uric acid
stress can have a similar effect
WBC increase
patient who make an extremely tight fist or pumps the hand can increase lactate by as much as 100 percen or more
changes in posture cna influence lab results due to a chanfge in blood volume
lying down to standing will have an increase in blood pressure
List the tests that require chilling or warming and explain why these steps are necessary.
chilling of samples
released potassium from the cells and elevates the serum potassium values. other analytes are also affected
ammonia
acid phosphatase
catecholamines
lactic acid
pH/blood gases
warming of samples
tests need to be maintained at body temp
best method of maintaining this temp is to wrap the sample in a heel warmer, or to use a plastic black that is maintained at body temp before taking it to the patient
tests that must be maintained at 37º C are cold agglutinins & cryoglobulin
Describe situations that would result in re-collection or rejection of a sample.
when a test result is not consistent with previous test results, it is always recommended to redraw and run the test again
Describe methods of transporting samples.
pneumatic tube system
moving samples within a building or to another building a short distance may be accomplished by a pneumatic tube system
absorbent wrap
transporting samples long distances by an outside agency, requires teh sample to be wrapped
explain the laws that regulate compliance
antikickback law
prohibits the knowing and willful payment or offer of any remuneration directly or indirectly in return for inducing, referring, or soliciting services, including lab testing paid for by a federal health program
stark law
forbids physician from referring sample to a lab in which physician or immediate family member has financial interest
false claims act
prohibits knowingly presenting false claim to gov
prohibits changing billing code (upcoding) to increase reimbursement
billing for lab tests that are not medically necessary for diagnosis and treatment
civil monetary penalties law
prohibits claims for service not provided as claims
many states have their own set of lawys
not limited to medicare and medicaid programs
penalties vary depending ons tate
discuss why it is essential that laboratories maintain compliance and follow these laws
ensures that the customer is not being overcharged for testing or charged for testing that was not ordered and that unnecessary testing not being conducted
discuss the best way for a phlebotomist to avoid injury-related lawsuits
follow established procedures and practices
be observant of the patient
describe a situation in which a phlebotomist would need to make an ethical decision
phlebotomist must treat patients as they would like to be treated themselves
phlebotomist see many patients at their worst
may find it difficult to be ethical and professional with these patients
phlebotomist often has to deal with dying, death, and grief for the first time
