1. What is innate immunity? - ANSWER ✔ provides immediate protection and
is nonspecific, meaning it provides protection against all invaders.
2. What is adaptative immunity? - ANSWER ✔ Can take 7-10 days to provide
protection, but it is specific to the antigens.
3. What is antigen? - ANSWER ✔ a foreign agent that triggers the production
of antibodies by the immune system
4. What is antibody (immunoglobulin)? - ANSWER ✔ a protein used by the
immune system to identify and neutralized foreign agents, such as viruses
and bacteria
5. What is autoantibody? - ANSWER ✔ an antibody made by the immune
system that attacks an individual's own proteins
6. What is lysozyme? - ANSWER ✔ an enzyme that dissolves bacterial cell
walls.
,7. What is pyrogens? - ANSWER ✔ Molecules that cause the systemic
response of fever
8. What is Humoral immunity? - ANSWER ✔ interaction to produce
antibodies against the antigen (B-Cell function or humoral immunity)
9. What is cell-mediated immunity? - ANSWER ✔ is the main mechanism by
which the body fights the tubercle bacillus and starts a few weeks after
infection.
10.What is Human Leukocyte antigen system? - ANSWER ✔ known as major
histocompatibility complex (MHC) in humans, HLA system as the genes are
expressed on the surface of the WBC.
11.What is alloimmunity? - ANSWER ✔ Four types of tissue transplants are
possible—allogeneic, syngeneic, autologous, and xenogenic.
§ Allogeneic transplants are those in which the tissue used is from the same
species and is of similar tissue type, but it is not identical.
12.WHAT IS NATURAL PASSIVE ACQUIRED IMMUNITY - ANSWER ✔
Antibodies are passed directly from mother to child to provide temporary
protection: no memory.
13.EXAMPLE OF NATURAL PASSIVE ACQUIRED IMMUNITY -
ANSWER ✔ Passage of antibodies through the placenta or breast milk.
14.WHAT IS ARTIFICIAL PASSIVE ACQUIRED IMMUNITY - ANSWER
✔ Antibodies are injected into the body (antiserum) to provide temporary
protection or to minimize the severity of an infection. There is no memory.
,15.EXAMPLE OF ARTIFICIAL PASSIVE ACQUIRED IMMUNITY -
ANSWER ✔ hepatitis B immune globulin OR Gamma globulin injection to
treat immunologic disease, such as idiopathic thrombocytopenia purpura;
human immunoglobulin to treat hepatitis A and B.
16.DIFFERENTIATE VACCINE TYPES: LIVE ATTENUATED VACCINES
- ANSWER ✔ are created from weakened wild viruses or bacteria that can
replicate without causing diseases. Live, attenuated vaccines create an
almost identical immune response as active infection.
§ Example: Varicella, MMR
17.DIFFERENTIATE VACCINE TYPES: INACTIVATED VACCINES -
ANSWER ✔ are made from whole or fractions of viruses or bacterial
antigen or the toxin produced by the bacteria. The response stimulated is
mainly humoral with little or no stimulation of cellular immunity.
§ Example: Polio, rabies, hepatitis A
18.DIFFERENTIATE VACCINE TYPES: FRACTIONAL VACCINES -
ANSWER ✔ are protein-based vaccines made by modifying the toxins
produced by some bacteria; the modification does not cause disease.
§ Example: Tdap and meningococcus
19.DIFFERENTIATE VACCINE TYPES: RECOMBINANT VACCINES -
ANSWER ✔ o are developed through genetic engineering technology and
can include the use of the pathogen's DNA, genetic medication of a
pathogen, and a viral vector which is a virus that has been modified to insert
genetic material into cells.
§ Example: Hepatitis B, HPV, COVID-19
20.Class I - ANSWER ✔ Benefit >>> Risk
, Procedure/Treatment SHOULD be performed or administered
21.Class IIa - ANSWER ✔ Benefit >> Risk
It is REASONABLE to perform procedure/administer treatment
22.Class IIb - ANSWER ✔ Benefit > (or equal to) Risk
Procedure/treatment MAY BE CONSIDERED
23.Class III - ANSWER ✔ No benefit: Not helpful or no proven benefit
Harm: excess cost w/o benefit/harmful or harmful to patients
24.Mortality related to anesthesia - ANSWER ✔ -Inadequate patient
preparation (preop assessment)
-Inadequate postop management
-Wrong choice of anesthetic technique
-Inadequate crisis management
25.S&S Acute Cannabis use - ANSWER ✔ Tachycardia, labile BP, headache
Euphoria, dysphoria, depression, occasional anxiety & panic reactions,
psychosis (rare)
Poor memory & decreased motivation with chronic use
26.S&S Acute Cocaine & Amphetamines - ANSWER ✔ Tachycardia, labile
BP, HTN, MI, arrhythmias, pulm edema
Excitement, delirium, hallucinations to psychosis
Euphoria: feeling of excitation, well-being, and enhanced physical strength
& mental capacity
Hyperreflexia, tremors, convulsions, mydriasis, sweating, hyperpyrexia,
exhaustion, coma w/ OD
