,Which type of genetic disease affects males more Sex-Linked recessive. Since males only have one X and one Y, if the affected
frequently than females? chromosome has the illness, it will be expressed.
In which two conditions are chromosomal abnormalities Intellectual disability and fetal miscarriage. Chromosome abnormalities are the
the leading known cause? leading known cause of intellectual disability and fetal miscarriage.
What are three examples of prenatal diagnostic studies? 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.
Which genetic disorder is characterized by the presence of Cri du chat syndrome (translated as "cry of the cat") is caused by a DNA deletion.
a zygote having one chromosome with a normal This term describes the cry often heard from a baby affected by the syndrome. Cri
complement of genes and one chromosome with a missing du chat syndrome can present as a microcephalic, low birth-weight baby with a
gene? piercing cry.
How can an X-linked recessive disease skip generations? 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.
Which type of risk is referred to as the ratio of the disease Relative risk is a ratio of probability, not an actual occurrence of disease.
rate among the entire population to the disease rate in an
unexposed population?
What are the empirical risks for most multifactorial Many factors from lifestyle to genetics affect multifactorial diseases. Observation
diseases based on? and evaluation of each case individually provides the most thorough and accurate
assessment.
What refers to the silenced gene of a gene pair. The imprinted gene is the silent gene of a gene pair.
What is the primary reason that some older adults have The underlying chronic illness exists.
impaired inflammation and wound healing? A generalized inflammatory response seen in chronic illness depletes the body's
reserves to fight against illness.
Which cells are the body's primary defense against Eosinophils are the body's primary defense against parasites.
parasite invasion?
What Phagocytes bacteria? Macrophages work by eating or phagocytosing bacteria.
What is the first response to a foreign pathogen? Helper T cells
Which characteristic is the most important determinant of Immunogenicity is primarily based on the ability to recognize something foreign.

Which four infections are considered fungal infections? 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.
When is the earliest after sexual transmission of HIV that Lab testing can detect HIV RNA 4 to 10 days after sexual transmission, whereas
lab results can detect infection? 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.
What is a characteristic of exotoxins? Exotoxins are released during bacterial growth.
Which dietary lifestyle choice has been associated with a The results of decreased fat consumption have been widely studied and have
decreased risk for developing colon cancer? demonstrated a decreased risk of developing colon cancer.
Which cancer is an individual who has worked with Asbestos exposure results in an increased risk of lung and lung lining cancer.
asbestos for over 40 years most likely to develop?
Which statement is true regarding ultraviolet (UV) light? UV light causes basal cell carcinoma and squamous cell carcinoma when the UVB

individual's literacy level.

What is a red flag for low healthcare literacy? Low literacy often leads to perceived noncompliance to medical instructions,
including medication instructions. Ensuring the patient fully understands all

The inflammatory response is a defense mechanism designed to remove damaged
tissue so the body can heal.
