Miscellaneous Flashcards
Hct below this is considered anemia
Hct <2.5
MCHC Reference Range
33-37
What stains in a Reticulocyte?
the remnant ribosomal RNA reticulum stains blue with Methylene Blue
Reticulocyte levels measure
Rate of production and release of red cells by the marrow into the peripheral blood
Adult/Pediatric Reticulocyte Count Reference Range
Adult 0.5-1.5%
Pediatric 3.0-7.0%
When should reticulocyte count peak after acute hemorrhage?
6-10 days afterwards
Anticipated skin, eye, membrane or parenteral contact with blood or OPIM that may result form performance of an employee’s duties
Occupational Exposure
Specific contact with blood/OPIM capable of transmitting a BBP
Exposure Incident
MCC of exposure
Needle-sticks after use
Practice of isolating all body substances of individuals undergoing medical treatment especially highly infectious, goes further in isolating the workers from pathogens
Includes precautions against airborne transmission, droplet transmission, skin contact or prion diseases
Body Substance Isolation
Combines Universal and BSI Precautions
Includes protection of pt as well as health care worker
Standard Precautions
Treat all human blood and OPIM as if known to be infectious with blood borne disease
Universal precautions
Most common mode of transmission of pathogens
Hands!
