Which of the following is responsible for the dramatic increase in life expectancy during the twentieth
- A. Technology increases in the field of medical laboratory research
- B. Advances in surgical techniques and procedures
- C. Sanitation and other public health activities
- D. Use of antibiotics to fight infections
Correct Answer: C
Rationale: The correct answer is C: Sanitation and other public health activities. Sanitation measures such as clean water supply, waste disposal, and public health initiatives like vaccination programs have played a crucial role in the increase in life expectancy. Improvements in sanitation reduce the spread of diseases, leading to a significant decline in mortality rates. This is supported by historical data showing that countries with better sanitation systems have higher life expectancies. Technology advances in medical laboratory research (A) may have contributed to specific treatments, but overall sanitation has a broader impact on population health. Advances in surgical techniques (B) and the use of antibiotics (D) have been important in treating illnesses but do not have the same population-level impact as sanitation.

Using the National CLAS as a guide, which service should be offered to clients who have LEP?
- A. Availability of interpreter services at a minimal fee
- B. Language assistance in the client's preferred language
- C. Interpretation services using family members
- D. Trained interpretation within 48 hours of hospital admission
Correct Answer: B
Rationale: The correct answer is B: Language assistance in the client's preferred language. According to the National CLAS Standards, offering language assistance in the client's preferred language ensures effective communication and understanding of healthcare services. This approach respects the client's linguistic and cultural needs, promoting patient-centered care and reducing the risk of errors due to language barriers. Availability of interpreter services at a minimal fee (A) may still pose financial barriers for clients with LEP. Using family members for interpretation services (C) can compromise confidentiality, accuracy, and impartiality. Trained interpretation within 48 hours of hospital admission (D) is not timely enough for immediate healthcare needs.
Persons in an auditorium may have been exposed to a disease. If they are infected, it is crucial that
- A. The negative predictive value
- B. The positive predictive value
- C. The sensitivity of the test
- D. The specificity of the test
Correct Answer: A
Rationale: The correct answer is A: The negative predictive value. In this scenario, it is crucial to know the likelihood of a person not being infected if the test result is negative. Negative predictive value assesses the probability of a person truly being disease-free when the test result is negative. This is important for determining the risk of spreading the disease within the auditorium.
Explanation for other choices:
B: The positive predictive value - While important in clinical settings, in this case, determining the accuracy of positive test results is not as critical as ruling out disease transmission.
C: The sensitivity of the test - Sensitivity measures the ability of the test to correctly identify those with the disease, not necessarily ruling out disease transmission among those with negative results.
D: The specificity of the test - Specificity measures the ability of the test to correctly identify those without the disease, which is not directly related to preventing disease spread in this context.
The nurse often has to make resource allocation decisions. Which of the following best describes the
- A. The specific moral or ethical principle related to the situation
- B. The cheapest, most economical approach
- C. The most rational probable outcome
- D. The needs of the aggregate rather than a few individuals
Correct Answer: A
Rationale: The correct answer is A: The specific moral or ethical principle related to the situation. In resource allocation decisions, nurses must consider ethical principles such as beneficence, justice, autonomy, and nonmaleficence. By applying these principles, nurses can ensure fair and ethical distribution of resources. Choice B (The cheapest, most economical approach) may not always align with ethical principles and could compromise quality of care. Choice C (The most rational probable outcome) may not necessarily consider ethical implications. Choice D (The needs of the aggregate rather than a few individuals) could lead to neglecting individual patient needs.
Which of the following actions would most likely be performed by a public health nurse?
- A. Asking community leaders what interventions should be chosen
- B. Assessing the community and deciding on appropriate interventions
- C. Using data from the main health care institutions in the community to determine needed health
- D. Working with community groups to create policies to improve the environment
Correct Answer: A
Rationale: The correct answer is A because public health nurses collaborate with community leaders to understand community needs and preferences. They rely on community input for effective interventions. Option B is incorrect because assessing and deciding interventions should involve a multidisciplinary team, not a sole decision by the nurse. Option C is incorrect as it focuses on institutional data rather than community input. Option D is incorrect because creating policies is typically a collaborative effort involving various stakeholders.
Which statement accurately describes a large portion of foreign-born residents of the United States?
- A. They tend to live in major metropolitan areas.
- B. Most reside in rural areas.
- C. Few have a high school education.
- D. They are refugees and non-immigrants.
Correct Answer: A
Rationale: The correct answer is A: They tend to live in major metropolitan areas. This is because major metropolitan areas offer more job opportunities, cultural diversity, and support services for foreign-born residents. Rural areas typically have fewer resources and job opportunities. Choice B is incorrect because most foreign-born residents do not reside in rural areas. Choice C is incorrect as many foreign-born residents do have a high school education or higher. Choice D is incorrect because foreign-born residents include a diverse group of individuals, not just refugees and non-immigrants.
