QUESTION: What are three examples of prenatal diagnostic studies? - ANSWER-Chorionic villus
sampling (CVS), amniocentesis, and preimplantation genetic testing (PGT) are examples of
prenatal diagnostic studies and are performed in vitro. CVS is a form of genetic testing that
provides genetic information found in utero and is usually performed between weeks 11 and 14
of pregnancy. An amniocentesis is a form of genetic testing that evaluates amniotic fluid and is
usually performed during the second trimester, between weeks 15 and 20 of pregnancy. PGT is
performed on the embryo prior to implantation.
QUESTION: Which genetic disorder is characterized by the presence of a zygote having one
chromosome with a normal complement of genes and one chromosome with a missing gene? -
ANSWER-Cri du chat syndrome (translated as "cry of the cat") is caused by a DNA deletion. This
term describes the cry often heard from a baby affected by the syndrome. Cri du chat
syndrome can present as a microcephalic, low birth-weight baby with a piercing cry.
QUESTION: How can an X-linked recessive disease skip generations? - ANSWER-The disease can
be transmitted through female carriers.

Since females have two copies of the X chromosome, the mother may provide an unaffected X
to a daughter or son. Furthermore, a daughter may not show signs of the disease because she
has the other X (the only X the father can give to a female) to cancel it out.
QUESTION: Which type of risk is referred to as the ratio of the disease rate among the entire
population to the disease rate in an unexposed population? - ANSWER-Relative risk is a ratio of
probability, not an actual occurrence of disease.
QUESTION: What are the empirical risks for most multifactorial diseases based on? - ANSWER-
Many factors from lifestyle to genetics affect multifactorial diseases. Observation and
evaluation of each case individually provides the most thorough and accurate assessment.
QUESTION: What refers to the silenced gene of a gene pair. - ANSWER-The imprinted gene is
the silent gene of a gene pair.
QUESTION: What is the primary reason that some older adults have impaired inflammation and
wound healing? - ANSWER-The underlying chronic illness exists.
A generalized inflammatory response seen in chronic illness depletes the body's reserves to
fight against illness.
QUESTION: Which cells are the body's primary defense against parasite invasion? - ANSWER-
Eosinophils are the body's primary defense against parasites.

QUESTION: What Phagocytes bacteria? - ANSWER-Macrophages work by eating or
phagocytosing bacteria.
QUESTION: What is the first response to a foreign pathogen? - ANSWER-Helper T cells
QUESTION: Which characteristic is the most important determinant of immunogenicity when
considering the antigen? - ANSWER-Immunogenicity is primarily based on the ability to
recognize something foreign.
QUESTION: How are erythrocytes destroyed when mismatched blood is administered, causing
an ABO incompatibility? - ANSWER-The complement pathway is activated in response to blood
incompatibility.
QUESTION: What is the hypersensitivity reaction that causes atopic dermatitis? - ANSWER-An
immediate (type I) hypersensitivity reaction causes atopic dermatitis.
QUESTION: Which four infections are considered fungal infections? - ANSWER-Infection with a
fungus is called mycosis and includes dermatophytes (e.g., tineas, which refers to several skin
mycoses, including ringworm and athlete's foot) and yeasts, which include candida and
aspergillus.

QUESTION: When is the earliest after sexual transmission of HIV that lab results can detect
infection? - ANSWER-Lab testing can detect HIV RNA 4 to 10 days after sexual transmission,
whereas HIV antibody testing may take 23 to 90 days to result in a positive test. Repeat testing
may be needed to rule out a false negative test due to testing too soon after exposure,
especially if a high likelihood of exposure is suspected.
QUESTION: Which type of genetic disease affects males more frequently than females? -
ANSWER-Sex-Linked recessive. Since males only have one X and one Y, if the affected
chromosome has the illness, it will be expressed.
QUESTION: In which two conditions are chromosomal abnormalities the leading known cause? -
ANSWER-Intellectual disability and fetal miscarriage. Chromosome abnormalities are the
leading known cause of intellectual disability and fetal miscarriage.
QUESTION: What is a characteristic of exotoxins? - ANSWER-Exotoxins are released during
bacterial growth.
QUESTION: Which dietary lifestyle choice has been associated with a decreased risk for
developing colon cancer? - ANSWER-The results of decreased fat consumption have been
widely studied and have demonstrated a decreased risk of developing colon cancer.
QUESTION: Which cancer is an individual who has worked with asbestos for over 40 years most
likely to develop? - ANSWER-Asbestos exposure results in an increased risk of lung and lung
lining cancer.
