You have been asked to evaluate the federally funded dental program at a local senior
citizen center in a northeastern state. Located in a diverse inner-city neighborhood of a large
metropolitan city, the center serves an ethnically diverse population of varying
socioeconomic status. Community water supplies are fluoridated, and students from local
dental hygiene programs occasionally provide oral health education and oral screenings
under the supervision of a licensed dentist. Both a registered nurse and a dietitian are
available for you to consult with, as are a dentist and a gerontologist. Breakfast and lunch are
served five days a week, and movies, complete with soft drinks and snacks, are available
most afternoons.You wish to describe variability of plaque scores taken from members of
your target population during a screening session, using measures of dispersion. Each of
the following is a measure of dispersion - Correct Answer A. correlation
Correlation is not a measure of dispersion. Rather, correlation is a statistical measure for
determining the strength of the linear relationship between two or more variables. Range, a
measure of dispersion, is the spread between the highest and the lowest scores in a
distribution. Variance, a measure of dispersion, is the measure of average deviation or
spread of scores around the mean. Standard deviation, a measure of dispersion, indicates
the distribution of scores in relation to the mean
Manifestations of bulimia include all of the following EXCEPT one. Which one is the
EXCEPTION?
,A.
Recurrent bingeing
B.
Dehydration
C.
Self-induced vomiting
D.
Consumption of 300 to 600 calories per day
E.
Depression - Correct Answer D.
Intake of calories in bulimia ranges from 3,500 to 20,000. Recurrent bingeing followed by
vomiting is a major characteristic of bulimia. Dehydration results from frequent vomiting.
Vomiting is induced to reduce caloric intake from the bingeing. Depression is an integral
component to this psycho-psychologic condition.
A radicular cyst is most frequently located at the apex of the root and is most likely
associated with supernumerary teeth.
A dentigerous cyst is most likely associated with carious lesions.
A.
Both statements are true.
B.
Both statements are false.
C.
The first statement is true, the second is false.
D.
The first statement is false, the second is true. - Correct Answer b.
Radicular cysts, usually found at the apex of the root, are most likely associated with carious
teeth. A radicular cyst is not commonly seen with a supernumerary tooth, unless the tooth is
erupted and a carious lesion is present. Dentigerous cysts are most likely associated with
unerupted teeth. Note that in impacted third molars, a dentigerous cyst is most likely to form
in the area surrounding the crown of an unerupted tooth.
Which of the following interventions is NOT a treatment for leukemia?
,A.
Renal surgery
B.
Irradiation
C.
Chemotherapy with blood transfusions and antibiotics
D.
Interferon therapy
E.
Bone marrow transplant - Correct Answer A
.
Renal surgery is not a treatment for leukemia. Irradiation is used to destroy malignant cells.
The combination of chemotherapy with blood transfusions and antibiotics destroys
malignant cells, injects normal cells, and reduces the chance of infection. Interferon
therapy, first described in 1957 but not widely used until more recently, has been shown to
be an effective treatment for leukemia. Bone marrow transplant replaces abnormal cells
with normal cells.
Products that contain amorphous calcium phosphate (ACP) can be appropriately
substituted for fluoride therapy because ACP contains the same minerals as the
hydroxyapatite crystals of tooth enamel.
A.
Both the statement and reason are correct and related.
B.
Both the statement and reason are correct but NOT related.
C.
The statement is correct, but the reason is NOT.
D.
The statement is NOT correct, but the reason is correct.
E.
NEITHER the statement NOR the reason is correct. - Correct Answer D
Which of the following cartilages is signet ring-shaped?
A.
Cricoid
, B.
Arytenoid
C.
Corniculate
D.
Cuneiform - Correct Answer A
The cricoid cartilage is signet ring-shaped and is attached by membranes to the upper part
of the trachea. The arytenoid cartilages, a pair of small three-sided pyramids, are located on
the back of the larynx. The corniculate cartilages are two tiny cones, one on the apex of each
arytenoid cartilage. The cuneiform cartilages are two tiny rods, placed in the mucous
membrane folds, that connect the arytenoids to the epiglottis.
Determination of who should receive treatment when all cannot be treated is known as
A.
equity.
B.
need.
C.
public policy.
D.
distributive justice. - Correct Answer D
Distributive justice, also known as allocation of scare resources, is defined as the
determination of who should receive treatment when all cannot be treated. Closely related
and integral to distributive justice is equity. This is the concept that all persons receive equal
treatment. A factor considered in all distributive justice determinations is the prioritization of
the needs of the individual, legally referred to as need. Public policy differs from distributive
justice and is defined as a system of plans of actions, regulatory measure, laws, and funding
priorities.
