1. What is the measure of the number of existing cases of a disease in a specific population at a given time?

• A. Incidence
• B. Prevalence
• C. Mortality rate
• D. Morbidity rate

Correct answer: B

Rationale: Prevalence is the correct answer as it refers to the number of existing cases of a disease in a specific population at a given time. Incidence, on the other hand, refers to the number of new cases of a disease in a defined population over a specific period. Mortality rate is the measure of the number of deaths in a particular population due to a specific cause, while morbidity rate is the frequency of a disease in a specific population.

2. An infant weighed 7 pounds 8 ounces at birth. If growth occurs at a normal rate, what would be the expected weight at 6 months of age?

• A. Double the birth weight
• B. Triple the birth weight
• C. Gain 6 ounces each week
• D. Add 2 pounds each month

Correct answer: A

Rationale: The correct answer is A: 'Double the birth weight.' Infants typically double their birth weight by 6 months of age. This is a common milestone in healthy infant growth and development. Choice B is incorrect because tripling the birth weight would be excessive and not in line with normal growth patterns. Choice C, 'Gain 6 ounces each week,' is not accurate as infant growth is not linear each week. Choice D, 'Add 2 pounds each month,' is also incorrect as this rate of growth would be too rapid and unrealistic for healthy infant development.

3. Which of the following measures the frequency of new cases of the phenomenon during a given period of time?

• A. prevalence rate
• B. proportionate mortality rate
• C. case fatality rate
• D. incidence rate

Correct answer: D

Rationale: The correct answer is D, incidence rate. Incidence rate measures the frequency of new cases of a phenomenon, providing important information about the risk of developing the condition. Prevalence rate (choice A) reflects both old and new cases, proportionate mortality rate (choice B) is the proportion of deaths due to a specific cause, and case fatality rate (choice C) measures the proportion of deaths among confirmed cases, not just new cases.

4. The nurse is screening children at a local community health clinic for infectious diseases. Which child is at highest risk for hepatitis B virus (HBV)?

• A. A newborn.
• B. A 3-year-old.
• C. A 7-year-old.
• D. An 11-year-old.

Correct answer: A

Rationale: The correct answer is A: a newborn. Newborns are at the highest risk for HBV due to potential transmission from the mother. The hepatitis B virus can be transmitted from an infected mother to her baby during childbirth. Choices B, C, and D are incorrect because newborns have a higher risk due to this mode of transmission, making them more vulnerable compared to older children.

5. A nurse organizes a community action group to help resolve health problems in a low-income neighborhood with a large population of recent immigrants from Africa. What problem should the nurse address first?

• A. High rate of unemployment.
• B. Low immunization rate of children.
• C. Provision of substandard health care.
• D. Access to bilingual care providers.

Correct answer: B

Rationale: The correct answer is B: Low immunization rate of children. Addressing low immunization rates is crucial as it directly impacts the health of children and the community by preventing the spread of infectious diseases. Option A, high rate of unemployment, though important for overall well-being, is not the most immediate health concern. Option C, provision of substandard health care, is a significant issue but may not be as urgent as ensuring children are immunized. Option D, access to bilingual care providers, is important for effective communication but is not as critical as addressing low immunization rates in this scenario.
