The school health nurse observes that a large percentage of Hispanic children in the elementary school are overweight. Which screening program should the nurse choose to target the highest priority health concern for this population?

A) Evaluate the teacher's ability to identify pediculosis capitis 2 months after initiation of the program:
Evaluating the teachers’ ability to identify pediculosis capitis is important for ongoing surveillance, but it does not directly measure the effectiveness of the program in reducing the prevalence of the condition. This action focuses more on teacher training rather than the program's overall impact.

B) Measure the prevalence of pediculosis capitis among the children after four months:
Measuring the prevalence of pediculosis capitis among children after the implementation of the program is the most effective way to evaluate the program's success. By comparing the prevalence before and after the program, the nurse can assess whether the interventions (educational pamphlets and regular assessments) have led to a reduction in cases.

C) Survey parents 3 weeks after pamphlets are sent home to assess their understanding of the condition:
Surveying parents about their understanding of pediculosis capitis is useful for evaluating the reach and impact of the educational component. However, it does not directly measure the effectiveness of the program in reducing the actual prevalence of pediculosis capitis among children.

D) Conduct an initial examination of each child in the school to obtain baseline data:
Conducting an initial examination provides valuable baseline data on the prevalence of pediculosis capitis before the program begins. However, this action alone does not evaluate the effectiveness of the program; it must be followed by assessments after the program’s implementation to determine if there has been a reduction in cases.

A. Low income families living in cramped quarters: Hepatitis A is primarily spread through the fecal-oral route, often through contaminated food or water. Individuals living in overcrowded or unsanitary conditions are at a higher risk due to the increased likelihood of exposure to contaminated sources and poor hygiene practices. Thus, low-income families living in cramped quarters are particularly vulnerable to hepatitis A.

B. Sexually active persons with multiple partners: While hepatitis B and C are more commonly associated with sexual transmission, hepatitis A is less commonly spread through sexual activity. Hepatitis A transmission is more directly related to poor sanitation and hygiene rather than sexual behavior alone.

C. IV drug users who share needles: Intravenous drug users who share needles are at high risk for hepatitis B and C, not hepatitis A. Hepatitis A is not typically transmitted through blood but rather through contaminated food and water.

D. Those who have recently received a blood transfusion: Hepatitis A is not transmitted through blood transfusions. Hepatitis B and C are the types of hepatitis associated with blood transfusions. Hepatitis A is spread through ingestion of contaminated food or water.
