Hospital Corpsman (HM) Personnel Qualification Standards (PQS) Practice Test

In the Laboratory module of the electronic program of record (AHLTA, CHCS), you track the complete lifecycle of a lab item, from ordering to results, with fields that specifically identify what was tested, the results, and the context of the test. The essential elements are the lab test itself, the lab results, the date the specimen was collected, and the date the test was ordered, along with the type of sample and specimen, the Medical Treatment Facility (MTF) where it was processed, and the current status of the item. These fields together convey what was done, when, where, and what came back, which is exactly what the Laboratory module is designed to document. The other options describe data elements associated with different modules—imaging data for Radiology, notes-related details for Clinical Notes, and encounter details for Previous Encounters—so they don’t belong to the Laboratory module.
