500 mL

Patients have the right to what?

Under the Patient Bill Of Rights they always have the option to decline medical treatment and to know what tests are being performed on them.

What can you NOT give a patient?

Results or a diagnosis. Because you are not medically qualified to do so.

Negligence is?

Failure to give appropriate care. DON'T BE NEGLIGENT!

PPE stands for?

Personal Protective Equipment

One of the most important practices is?

Hand Washing is one of the most important (and easiest) practices used to prevent transmission of bloodborne pathogens

Needles should never be

recapped

Sharps containers must be what?

puncture-resistent, leak proof on the sides and bottom and must be labeled or color-coded

Types of Hazards

Biologic - Infectious agents that can cause bacterial, viral, fungal or parasitic infections

Sharps - Needles, lancets and broken glass can puncture and cut, causing blood-borne pathogen exposure

Chemical - Preservatives and chemicals used in the laboratory. Exposure to Toxin, Carcinogenic or caustic substances

Fire or explosive - bunsen burners, oxygen and chemicals can cause burns or dismemberment

Physical - wet floors, heavy lifting ance cause falls, sprains and strains

• ALLERGIC reaction ** - Latex sensitivity is a PHYSICAL reaction to care worker allergic reation to the patient

In infection control WHO is the agent?

Person

In infection control WHAT is portal of exit?

Needle

In infection control WHAT can we control?

Mode Of Transmission OR exit of infection

In infection control WHAT is a portal of entry?

Mucas membrane

In infection control WHO is a susceptible host?

Person

Mode of Transmission

Specific ways in which microorganisms travel from the reservoir to the suseptible host

Five main types or mode of transmission

contact - direct and indirect (fomite)

Droplet - Cold, Flu and sneezing

Airborne - viral - breath in

common vehicle - person, fomite and not handwashing

vector borne - illness that is transmitted through an invertebrate, such as an insect

Mode of infection

the point in the infection chain where we aim at preventing the spread of infectious disease

Standard precautions do what?

Infection control method designed to prevent direct contact with blood and other body fluids and tissues by using a barrier of protection and work control practices.

What do we assume all patients to be?

Patients are presumed to be infective for blood-borne pathogens

Standard precautions consist of what itmes?

Gloves - when collecting and handling body fluids, or tissue specimen

Face shield - when danger of splashing on mucous membranes

Disposal - dispose of all needles and sharp objests in punture-proof containers, WITH OUT RECAPPING

Disinfectants - clean fluid spills, thus killing pathogenic organisms

Medical Asepsis

This condition is best defined as "the destruction of pathogenic microorganisms after they leave the body". It also involves enviromental hygien measures such as equipment cleaning and disinfection procedures. Methods of medical asepsis are Standard Precautions and Transmission-based Precautions

What are barrier protections?

Masks

Gloves

Face Shields

Resirator

Gloves

How do you remove PPE equipment?

1st - Gloves

2nd - Gown

3rd - Shield

What type of soap should be used?

Non-abrasive, antibacterial soap.

What do you do if blood splashes in the eye or mucous membane?

Flush with warm water (hotter the better) for 15 minutes

Report incident exposure to your supervisor ASAP!

Who cannot be identified in an incident report?

a minor

Bedside manner includes?

introduce yourself, ask patient name and b-day. Explain what you will be doing. Chat with patient to keep mind off poke. ADVISE them WHEN you are poking! Speak to them on a first name basis

What phase is best practice

"pleasant with the patient and professional with the poke".

If patient has an I.V. where do you draw blood?

Downstream from the I.V.

Double Mastectomy patients should ONLY have blood drawn from what?

Hands

Left Mastectomy patients should have blood drawn from what side?

Right side

What is a Fistula?

artificial connections of veins

What is a Graft?

artificial artery connection to vein

Sclerosis is?

Hard and cord like veins

For obese patients what vein is used?

Cephalic Vein is most likely to be the one you can palpate and draw blood from in an obese patient

Cephalic means what?

Head

Most common complication in Phlebotomy

Hematoma

To prevent a Hematoma

prevented if pressure is placed on the venipuncture site until bleeding stops

If a patient faints what is the 1st thing to do?

GET the needle out of the arm

Vasovagal Syncope is

fainting, dizziness before, during or after venipuncture

Circulatory System funtion

is todeliver oxyge, nutrients, hormones and enzymes to the cells. Transport cellular waste such as carbon dioxide and urea to the organs where they can be expelled from the body.

Circulatory exchange is done where?

capillary level

45% of blood is

formed elements -

Erythrocytes (red blood cells) = 99% of formed elements.

Leukocytes (white blood cells) and Thrombocytes (platelets)

All blood cells originate from

stem cells in the bone marrow

The heart acts as what?

two pumps (right and left sides)

Left and right sides of heart are connected by

two circulations, with each pump equipped with two valves the function of which is to maintain a one way flow of blood

Pulmonary circulations

carries deoxygentated blood from the right ventricle to the lungs. (alveoli) and return oxygenated blood from the lungs to the left atrium

Oxygenation takes place

at the alveoli - sacks in the lungs

Systemic circulation

carries oxygentated blood from the left ventricle throughout the body

Tricuspid valve

an atrioventricular valve, being situated between the right atrium and the right ventricle

Pulmonic valve

semi lunar valve situated between the right ventricle and the pulmonary artery

Mitral valve

(bicuspid valve) is another atrioventricular valve, being situated between the left atrium and the left ventricle

Aortic valve

semi lunar valve situated between the left ventricle and the aorta

How long does it take for a full circulation?

one minute

The average person weighting 155 pounds has

approximately 5-6 liters of blood in their system.

Blood composes of

7-9 percent of total body weight of a person

Blood has how much plasma?

55% is plasma

Plasma is what?

a clear, pale yellow fluid

what does plasma do?

it carries nutrients, lipids, glucose, sodium, magnesium, calcium, potassium, oxygen, carbon dioxide, nitrogen, antibodies, as wells as vitamins and hormones ect.

What is 45% of blood?

Red blood cells, White blood cells and Platelets. Known as the formed cellular elements

How long does your body take to regenerate RBC you lose during donation

6 to 8 weeks if you donate the maximum of 500 mL

Three layers of the heart are?

Endocardium

Myocardium

Epicardium

Endocardium

the endothelial inner layer lining of the heart

Myocardium

the muscular middle layer. This is the contractile element of the heart

Epicardium

the fibrous outer layer of the heart. The coronary arteries, which supply blood to the heart are found in this layer

Blood vessels are

Aorts, arteries, arterioles, capillaries, venules and veins, superior and inferior vena cava

Erythrocytes

Red blood cells or RBC's

Erthrocytes contain

hemoglobin, the oxygen-carrying protein.

Hemoglobin

enters the blood as an immature reticulocyte where in one to two days, it matures into erythrocyte.
