Final answer:
The priority nursing action upon a patient's arrival at a clinic is to determine and record the patient's history and vital signs as this information is critical for the safe and effective care of the patient.
Step-by-step explanation:
When a patient arrives at a clinic, the priority nursing action is to determine and document the patient's history and vital signs. This initial step is vital for providing direct supervision of a registered nurse and ensuring patient safety and the adequacy of care. This assessment forms the basis of patient care, which includes identifying patient needs, preparing for treatments such as dialysis, confirming the identity and specific medical needs of the patient, and ensuring that all medical procedures and treatments are conducted safely and effectively.
Documenting history and vital signs is essential because it allows healthcare providers to understand the patient's current condition, medical history, and any critical needs that may affect their care. This will also aid the medical team during treatments to monitor changes and adjust the care accordingly.
