After assessing the health care needs of an elementary school, the nurse determines that an increased prevalence of pediculosis capitis is a priority problem. The nurse develops a 2-month program with the goal to eradicate the condition in the school. The program includes educational pamphlets sent home to parents and regular assessment of children by the school nurse. Which action should the nurse implement to evaluate the effectiveness of the program?

Evaluate the teacher's ability to identify pediculosis capitis 2 months after initiation of the program.

Measure the prevalence of pediculosis capitis among the children after four months.

Survey parents 3 weeks after pamphlets are sent home to assess their understanding of the condition.

Conduct an initial examination of each child in the school to obtain baseline data.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

A) Review morbidity data for the city's population compiled by the Bureau of Vital Statistics:
This is the most comprehensive and reliable method for identifying the greatest health concern facing the city. Morbidity data provides statistical information on the incidence and prevalence of diseases and health conditions within the population, helping to identify major health issues based on objective data.

B) Conduct a random telephone survey to determine the public's perception about health problems:
While public perception is valuable, it may not accurately reflect the actual health concerns based on prevalence or incidence data. Public surveys can provide insights into perceived issues but are not as reliable for identifying the most pressing health concerns as concrete morbidity data.

C) Call American Medical Association members to determine the most frequently treated diagnoses:
This method might provide insights from a medical perspective but does not offer a complete picture of the health concerns across the entire population. It may also miss out on data from other healthcare providers and public health reports.

D) Survey major hospitals in the area to determine the most common reasons for admissions:
Although hospital admission data is useful, it represents only part of the health picture and may not capture all relevant health concerns in the community. It also does not include outpatient or preventive care data, which are important for a comprehensive health assessment.

A. 3/1,000. B. 30/1,000. C. 1.7/1,000. D. 15/1,000.

Correct Answer is B

Explanation

A) 3/1,000:
To calculate the rate per 1,000, you divide the number of new positive tests by the total number of students tested, then multiply by 1,000. For 15 new positive tests among 500 students, the rate is (15/500) * 1,000 = 30/1,000. Thus, 3/1,000 is incorrect.

B) 30/1,000:
The correct calculation for the rate per 1,000 is determined by dividing the number of new positive tests (15) by the total number of students tested (500) and then multiplying by 1,000. Therefore, (15/500) * 1,000 = 30/1,000. This rate accurately reflects the proportion of students with positive tests per 1,000.

C) 1.7/1,000:
The rate of 1.7/1,000 would result from incorrect calculations. Using the correct formula, the rate per 1,000 should be 30/1,000.

D) 15/1,000:
The rate of 15/1,000 suggests that there are 15 positive tests per 1,000 students, which does not reflect the actual number of new positive tests (15) among 500 students. The correct rate calculation yields 30/1,000, not 15/1,000.
