Diagnostic Testing and Lab Values Self-Study Course
Licensed Practical Nurses (LPNs) are responsible for providing safe, competent and quality care to clients. It is an expectation of practice that they will critically appraise all assessment data to arrive at the best nursing care for each individual client. This course provides information and learning activities related to diagnostic tests and laboratory (lab) values, one source of client assessment data.
The LPN should understand the rationale for conducting specific diagnostic and laboratory tests when delivering care, as well as the implications of the results of those tests. The course lists common diagnostic and lab tests and values in an organized manner, with opportunities for participants to test their knowledge through short case studies and interactive quizzes.
Entry level LPNs are expected to meet the knowledge requirement for obtaining, assessing and monitoring diagnostic tests and lab values commonly used in healthcare. This course is intended to review and extend the LPN’s knowledge pertaining to diagnostic tests and lab values so that safe and timely care may be delivered to clients.
