1. Assignment 1: Case Study Assignment: Assessment Tools and
Diagnostic Tests in Adults and Children
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. You also will review examples of

2. pediatric patients and their families as it relates to BMI.
· By Day 1 of this week, you will be assigned to one of the
following Assignment options by your Instructor: Adult
Assessment Tools or Diagnostic Tests (option 1), or Child
Health Case (Option 2).
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.
· If you are assigned Assignment Option 2 (Child), consider
what health issues and risks may be relevant to the child in the
health example.
o Based on the risks you identified, consider what further
information you would need to gain a full understanding of the
child’s health. Think about how you could gather this
information in a sensitive fashion.
o Consider how you could encourage parents or caregivers to be
proactive toward the child’s health.
