The median is the value that's exactly in the middle of a dataset when it is ordered12. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values2. The steps for finding themedian differ depending on whether you have an odd or an even number of data points123.
Based on the data provided in the image, we can calculate the median by arranging the vaccine counts in ascending order and finding the middle value. The counts in ascending order are: 5, 10, 16, 18, 30, 55, 71, 90,
114, 144, 195, and 200. Since there are an even number of data points (12), we take the middle value directly without averaging two middle values. So here it is option B - "55". This is consistent with the principles of median calculation123.

The initiative to increase lung cancer screenings for a patient population with a history of smoking falls under secondary prevention123. Secondary prevention aims to reduce the impact of a disease or injury that has already occurred2. This is done by detecting and treating disease or injury as soon as possible to halt or slow its progress2. In the context of healthcare, screenings are a common form of secondary prevention123. They allow for early detection of diseases like lung cancer, especially in high-risk groups such as smokers123. Early detection can lead to more effective treatment and better health outcomes123.

When planning an initiative to reduce barriers to healthcare in the community, it's important to understand the demographic makeup of the area. This includes information about occupations and housing types, which can provide insights into socioeconomic status, access to transportation, and other factors that may affect healthcare access.
Community planning maps showing transportation routes (Option A) could be useful in later stages of planning, particularly when considering the location of healthcare facilities or services. However, this information is not as fundamental as demographic data for initial planning.
Reports from the public health department showing pediatric obesity rates (Option C) could be relevant if the initiative specifically targets pediatric health or obesity. However, for a general initiative to redu

Detailed Explanation:
A pilot project allows for testing changes on a smaller scale, addressing concerns and gathering feedback before full implementation, which facilitates staff acceptance.
Option D: A pilot project
Piloting a change minimizes resistance by allowing for adjustments and staff involvement in the improvement process.
