DHE 101 QUIZ#3

American society of anesthesiologists describes 6 categories of physical status & provides examples of adaptations necessary for providing dental hygiene care for a patient in each category.

A patient with out apparent systemic disease (normal healthy patient)

A patient with mild systemic disease

A patient with severe systemic disease that limits activity but is not incapacitating

A patient with an incapacitating systemic disease that's a constant threat to life

A moribund patient not expected to survive 24 hours with or without care

• Natural resistance helps the body handle & destroy invading microorganisms, provided the number can be kept to a minimum.. 
• oral procedures that require penetration of tissues, such as giving anesthesia by injection or scaling subgingival pocket surfaces, can introduce bacteria into the blood stream organisms injected into the bloodstream could multiply and create abscess,

• potentially serious infectious bacteria disease that mainly affects the lungs.
• spread by droplet nuclei breathed directly into the lung. (Etiologic agent= mycobacterium tuberculosis)

• degree to which infected person produces infectious droplets
• amount and duration of exposure
• susceptible of recipient 
• some patients are more contagious than others
• maximum communicability- just before dose is diagnosed

resistance to first line drugs and at leat one of the 3 second line drugs

resistance to at least 2 of the first line drugs

when patients are non-complient in their required extended drug therapy or if the medication is not aucilable.

• Its for the dental team members and the patient.
• Used to prevent physical injuries and infections of the yes.

• for each appointment. 
• each hour during routine procedures or more frequently when it becomes wet

standard of acre that protects healthcare providers and their patients from pathogens that can be spread by blood or any other body fluid, excretion or secretion.

• Applies to all patients 
• applies to contact with blood, all body fluids (secretion or excretions)except sweat, regardless of whether they contain blood.
• nonintact (broken) skin
• mucous membranes

• spread of microorganisms from one source to another: person to person 
• or person to an inanimate object and then too another person.

dental practices/ clinic and possibly on instruments and equipment

airborne particles, called droplet nuclei.

• inflammation of the liver
• They start from blood to blood contact with an infected carrier of the virus.

• child: chickenpox/ varicella infection is an extremely contagious chilhood disease =. primarily a disease in children.
• may occur in adults not previously exposed and it will become more serious course of illness with more complications. 
• adult shingles/ zoster infection

• symptoms of a hypersensitive rxn
• range from dermatitis to life-threatening anaphylactic shock(immediate rxn)

• steam under pressure
• Gravity displacement/ self generation of steam forces out the air, stem enters to penetrate through the cassettes/ packages

High speed prevacuum: pump removes the air from the chamber and allows faster penetration of the steam for sterilization.

• inactivate spores and all forms of bacteria, fungi, and viruses. 
• applied at different time schedules the high level chemical is either a disinfectant or a sterilant.

inactivates all forms of microorganisms but do not destroy spores.

the herpes simplex infection of the fingers that result from the virus entering through minor skin abrasions most frequently around fingernail.

• Use PPE's (protective clothing, protective eyewear, gloves, mask)
• treat every patient like they have a disease (HIV)

• all forms of microorganism 
• except spores

• it kills/ destroys all forms of life (microorganisms, spores and viruses) 
• eg. steam under pressure (autoclave), dry heat oven, chemical vapor (unsaturated)

• Professional attitude.
• Sterilization & care of instruments.
• Disinfection procedures
• Prevent cross-contamination
• Exercise Safe Practice habits
• Standard precautions (universal precautions)
• Protect patients, dental health care workers, and others that may become exposed by acquiring infection in the environment of the office or clinical facility.
