When seeking to identify a patient’s health condition, advanced practice nurses can use a diverse selection of diagnostic tests and assessment tools; however, different factors affect the validity and reliability of the results produced by these tests or tools. Nurses must be aware of these factors in order to select the most appropriate test or tool and to accurately interpret the results.

Not only do these diagnostic tests affect adults, body measurements can provide a general picture of whether a child is receiving adequate nutrition or is at risk for health issues. These data, however, are just one aspect to be considered. Lifestyle, family history, and culture—among other factors—are also relevant. That said, gathering and communicating this information can be a delicate process.

For this Assignment, you will consider the validity and reliability of different assessment tools and diagnostic tests. You will explore issues such as sensitivity, specificity, and positive and negative predictive values. You will also consider examples of children with various weight issues. You will explore how you could effectively gather information and encourage parents and caregivers to be proactive about their children’s health and weight.

To Prepare

Review this week’s Learning Resources and consider factors that impact the validity and reliability of various assessment tools and diagnostic tests. 

By Day 1 of this week, you will be assigned to one of the following Assignment options by your Instructor: Adult Assessment Tools, Diagnostic Tests. Based on the Assignment option assigned to you, your Instructor will also assign you assessment tools or diagnostic tests to apply to either an adult  health example assigned to you. Note: Please see the “Course Announcements” section of the classroom for your assignments from your Instructor.

Search the Walden Library and credible sources for resources explaining the tool or test you were assigned. What is its purpose, how is it conducted, and what information does it gather?

Also, as you search the Walden library and credible sources, consider what the literature discusses regarding the validity, reliability, sensitivity, specificity, predictive values, ethical dilemmas, and controversies related to the test or tool.
