A public health nurse is implementing a program to improve vaccination rates among children in the community. Which intervention is most likely to be effective?

Correct Answer: A

Rationale: Offering vaccinations at convenient locations and times is the most effective intervention as it reduces barriers to access and makes it easier for parents to get their children vaccinated. This strategy directly addresses the issue of convenience and accessibility, which are common reasons for low vaccination rates. Distributing educational materials about vaccines (Choice B) can be helpful but may not directly address access issues. Providing incentives for getting vaccinated (Choice C) may be controversial and not sustainable in the long term. Hosting informational sessions for parents (Choice D) can be beneficial for education but may not directly improve vaccination rates as much as increasing access.

Correct Answer: C

Rationale: The slightly yellow color of the sclera is a normal racial variation found in the African-American population. Blue sclerae (Choice A) are associated with osteogenesis imperfecta, not a normal racial variation. Brown macules on the sclerae (Choice B) may indicate issues like melanoma or melanosis but are not a normal racial variation. Conjunctival pallor (Choice D) suggests anemia or decreased blood flow but is not a normal racial variation.

Correct Answer: A

Rationale: In the scenario of a primipara with a breech presentation and a prolapsed umbilical cord, the nurse should place the client in the supine position with the foot of the bed raised (Trendelenburg position). This position helps alleviate gravitational pressure by the fetus on the cord, preventing compression and reducing the risk of cord prolapse complications. Placing the client on the left or right side with legs elevated or in a prone position with the head elevated would not be appropriate in this situation, as they do not effectively relieve the pressure on the umbilical cord.

Correct Answer: C

Rationale: The most effective measure to indicate the program's effectiveness in a diabetes management class is the reduction in participants' average blood glucose levels. This measure directly reflects the impact of the program on managing diabetes and improving health outcomes. Choices A and B may provide valuable information but do not directly assess the program's impact on managing diabetes. Choice D, improvement in participants' knowledge about diabetes, is important but may not directly translate into improved diabetes management without actual health outcome measurements like blood glucose levels.

Correct Answer: A

Rationale: Offering free cancer screenings is the most likely activity to increase participation in the health fair. Providing direct services such as screenings not only attracts participants but also promotes early detection, which is crucial in cancer prevention. Distributing pamphlets, hosting a guest speaker, or providing informational booths are informative but may not have the same impact in driving participation as the opportunity for free screenings.
