Which of the following actions should a medical assistant take when applying a transdermal patch?

A. Computerized physician order entry: Computerized physician order entry (CPOE) is used by providers to enter and manage orders for tests, medications, and treatments, not for patient requests.
B. Patient portal: A patient portal is a feature of an electronic health record that allows patients to request refills, schedule appointments, and access their health information online.
C. Prescribing guide: A prescribing guide helps providers make decisions about medications but does not allow patients to make requests.
D. Computer on wheels: A computer on wheels (COW) is a mobile workstation used by healthcare providers for various tasks but does not directly facilitate patient requests.

A. Add thixotropic gel to the tube after venipuncture: Thixotropic gel is used in specific tubes for separating serum or plasma from blood cells and should be added during the manufacturing process, not after venipuncture.
B. Place the tubes in the centrifuge to chill after venipuncture to separate blood cells: Tubes should not be chilled before centrifugation unless specified by the test requirements. Most tubes are centrifuged at room temperature.
C. Invert additive tubes multiple times after filling the tube: Inverting additive tubes multiple times ensures proper mixing of the additive with the blood, which is crucial for accurate test results.
D. Mix the anticoagulant in the tube after filling the tube: The anticoagulant should be mixed by inverting the tube immediately after filling it, not after the fact.
