Public Health Foundations Questions
Question 1 of 5
In 2017 in a place populated by 50000 inhabitants there were the following numbers of injuries according to causes and deaths resulting from those injuries: The formula for the calculation of mortality rate per 100,000 resulting from violence is:
Correct Answer: A
Rationale: Mortality rate = (deaths from violence / population) x 100,000 = (5 / 50,000) x 100,000 = 10.
Question 2 of 5
Which denominator number is used for calculating the mortality rate of the disease?
Correct Answer: D
Rationale: Mortality rate = (deaths / population) x constant, using the average population as the denominator.
Question 3 of 5
Researches from the Cleveland Clinic (OH, USA) found that a microbiome present in breast tissue may be associated with breast cancer (Oncotarget 2017; 8:88122-88138). They hope to find a biomarker which help in fast and easy breast cancer diagnosis. Let us assume that they have already found such an biomarker and prepared a diagnostic test for detecting its presence. Using this test they examined 100 women with breast cancer and 100 healthy women who were diagnosed with other methods. They obtained the following results: Indicate the false interpretation of those results:
Correct Answer: B
Rationale: Specificity = TN / (TN + FP) = 89 / (89 + 11) = 89%, not 11%. Thus, B is false.
Question 4 of 5
Which of the following deaths are termed as premature death?
Correct Answer: D
Rationale: Premature death is typically defined as occurring before age 60 or 65 in public health contexts.
Question 5 of 5
In a population of 1.000.000 inhabitants 1.000 persons suffer from pancreatic cancer and in this population there were 200 deaths from that disease in one calendar year. Which of the following is the best overall measure of the described epidemiological situation with regard to pancreatic cancer?
Correct Answer: D
Rationale: Case fatality rate = (deaths / cases) = 200 / 1000 = 20% or 200/1000, best reflecting the disease’s lethality.
