Instead of solely looking at the WBC count, what must you consider when evaluating the hematologic status of a patient? - You must consider the individual absolute counts of each leukocyte type rather than the total WBC count. For such a critical evaluation, the first step is to order a CBC with differential. What are eosinophils? - Pro-inflammatory cells that are capable of either protecting or damaging the host depending on the situation. Their granules are toxic to parasites. What are r...

Diagnostic and Laboratory Tests are tools that provide information about the client. Tests may be used as basic screening as part of a wellness check. Frequently tests are used to help confirm a diagnosis, monitor an illness, and provide valuable information about the client's response to treatment. 3 Phases of Diagnostic Testing 1) Pretest 2) Intratest 3) Post-test Pretest Major focus is client preparation The nurse also need to know what equipment and supplies are ne...
