Final answer:
The primary responsibility of an LPN/LVN in the nursing process is to collect data on the health status of patients, which includes tasks like reporting vital signs and preparing solutions and equipment for dialysis treatments.
Step-by-step explanation:
In the collaborative process of delivering care based on the nursing process, the responsibility of the LPN/LVN under the direct supervision of a registered nurse is primarily to a) collect data on the health status of patients.
This process can involve reviewing patient history, current condition, and responding to patient needs. Specifically, LPNs may be tasked with taking and reporting a patient's vital signs, preparing solutions and equipment for treatments like dialysis, ensuring procedures are carried out accurately and maintaining sterility. Though they play a critical role in the delivery of care, the selection of a nursing diagnosis, organization of data for evaluations, and prioritization of nursing diagnoses are typically within the purview of the registered nurse or advanced practice nurses.
