Which of the following tasks is appropriate for a patient care technician?

Reinforcing teaching about a wound care technique is an appropriate task for a patient care technician. This role often involves providing support and education to patients under the supervision of licensed healthcare professionals. The technician can help reinforce information or instructions that have been provided by the nurse or physician, ensuring that the patient understands how to care for their wound properly. This may include demonstrating proper techniques, answering questions, and confirming patient understanding, all of which support the patient's recovery and adherence to treatment.

In contrast, performing an initial patient diagnosis requires advanced clinical judgment and training typically reserved for licensed medical professionals, such as doctors or nurse practitioners. Administering medications also falls outside the scope of practice for patient care technicians, as it requires specialized knowledge and training. Taking a patient’s medical history involves gathering sensitive medical information and interpreting it, a task best suited for professionals like nurses or physicians who can assess the implications of that history.
