Advanced Pathophysiology Exam 1 — Quiz
1.
A certain disease is currently found in 1 of every 10 people in the country, and 1,000
people contract the disease yearly. The population of the country is 4,500,000.
Which statement is correct?
A. The prevalence of the disease is 10% and the incidence is 0.02%.
B. The prevalence of the disease is 0.02% and the incidence is 10%.
C. Neither is correct.
D. There is insufficient data.
Correct Answer: A. The prevalence of the disease is 10% and the incidence is
0.02%.
,Rationale: Prevalence describes the proportion of a population that has a disease at
a particular time. One in ten people represents 10% prevalence. Incidence describes
the occurrence of new cases over a specified period. With 1,000 new cases among
4,500,000 people, the incidence is approximately 0.022%, or 0.02%.
2.
In relation to disease development, the term "etiology" refers to which of the
following?
A. Number of people with the disease
B. Cause of the disease
C. Definition of the disease
D. Outcome of the disease
Correct Answer: B. Cause of the disease.
Rationale: Etiology refers to the cause or origin of a disease. Causes may include
infectious organisms, genetic abnormalities, environmental exposures, trauma,
nutritional deficiencies, or combinations of factors.
3.
Which option best describes what is true about "symptoms"?
,A. Objective and measurable
B. The same as "signs"
C. Both of the above
D. Neither of the above
Correct Answer: D. Neither of the above.
Rationale: Symptoms are subjective experiences reported by the patient, such as
pain, nausea, fatigue, or dizziness. Signs are objective findings that can be observed
or measured by a healthcare professional. Therefore, symptoms are neither
objective/measurable findings nor synonymous with signs.
4.
In 1992, there were 980 deaths in a Midwestern city with a population of 1,000,000.
At the beginning of that year, 900 cases of AIDS existed in this population. During
the year, 250 new cases of AIDS were diagnosed, and 75 people died of the disease
in 1992. Using the data given above, what was the incidence rate per 100,000
population for AIDS?
A. 6
B. 25
C. 88
,D. 116
Correct Answer: B. 25.
Rationale: Incidence measures new cases occurring within a population during a
specified period. There were 250 new AIDS cases in a population of 1,000,000.
Thus, 250 ÷ 1,000,000 × 100,000 = 25 new cases per 100,000 population.
5.
What level of prevention is a blood pressure screening program for high school
students who are pregnant?
A. Primary
B. Secondary
C. Tertiary
Correct Answer: B. Secondary.
Rationale: Secondary prevention focuses on early identification of disease or
abnormal health conditions through screening and early intervention. Blood pressure
screening can identify hypertension or preeclampsia risk before serious
complications develop.
