UPDATE 2026/2027
Gene - CORRECT ANSWER The basic physical unit of inheritance. They are
passed from parents to offspring and contain the information needed to specify
traits.
Chromosome - CORRECT ANSWER An organized package of DNA found in
the nucleus of the cell. Different organisms have different numbers of
chromosomes. Humans have 23 pairs of chromosomes--22 pairs of numbered
chromosomes, called autosomes, and one pair of sex chromosomes, X and Y.
Genome - CORRECT ANSWER The entire set of genetic instructions found in a
cell.
Genomics - CORRECT ANSWER The study of the entire genome of an
organism. It's in contrast to genetics which can study individual genes one at a
time.
Genotype - CORRECT ANSWER An individual's collection of genes. The term
also can refer to the two alleles inherited for a particular gene.
Phenotype - CORRECT ANSWER An individual's observable traits, such as
height, eye color, and blood type.
,Genetic Screening - CORRECT ANSWER The process of testing a population
for a genetic disease in order to identify a subgroup of people that either have the
disease or the potential to pass it on to their offspring.
Genetic Testing - CORRECT ANSWER The use of a laboratory test to look for
genetic variations associated with a disease.
Pharmacogenomics - CORRECT ANSWER A branch of pharmacology
concerned with using DNA and amino acid sequence data to inform drug
development and testing.
Carrier - CORRECT ANSWER An individual who carries and is capable of
passing on a genetic mutation associated with a disease and may or may not
display disease symptoms.
Pedigree - CORRECT ANSWER A genetic representation of a family tree that
diagrams the inheritance of a trait or disease though several generations.
Marker - CORRECT ANSWER A DNA sequence with a known physical location
on a chromosome.
Dominant - CORRECT ANSWER The relationship between two versions of a
gene.
Codominance - CORRECT ANSWER A relationship between two versions of a
gene. Individuals receive one version of a gene, called an allele, from each parent.
An example is blood typing.
, Autosomal Dominant - CORRECT ANSWER The gene in question is located on
one of the numbered, or nonsex chromosomes, and that a single copy of the disease
associated mutation is enough to cause the disease.
different parts of the General Survey - CORRECT ANSWER The general survey
is a study of the whole person, covering the general health state and any obvious
physical characteristics
→physical appearance , body structure (stature, nutrition, symmetric), mobility
(gait, ROM), and behavior.
What does Systolic/Diastolic mean? - CORRECT ANSWER - The systolic
pressure is the maximum pressure felt on the artery during left - ventricular
contraction, or systole. (higher #)
- The diastolic pressure is the elastic recoil, or resting, pressure that the blood
exerts constantly between each contraction. (LOWER #)
What are healthy or "normal" vital signs for an adult? - CORRECT ANSWER -
temp: 98.6 (range 96.4-99.1)
* rectal measures .7-1 degree higher
*axillary measures 1 degree lower
- BP: <120/<80 in adults
-pulse: 50-95 bpm
-resp: 20 (range 16-25)
How do you take a blood pressure? - CORRECT ANSWER MANUAL: • Allow
at least a 5-minute rest before measuring
• Sit the patient in a chair with their back supported ) feet on the floor and legs
should not be crossed
• Arm must be supported at heart level and find Bracial artery
