Final answer:
An RN can delegate blood pressure checks to a UAP, who is responsible for documenting the readings and notifying the RN of abnormal results.
Step-by-step explanation:
When an RN delegates to the unlicensed assistive personnel (UAP) the task of performing blood pressure checks for a group of patients on a nursing unit, the UAP is primarily responsible for accurately measuring and documenting the blood pressure readings in the patients' medical records. The UAP must also notify the RN if any patient's blood pressure is outside the normal range.
However, the UAP is not responsible for assessing the patients' overall cardiovascular status, administering medications, or interpreting the significance of the blood pressure readings, as these actions require professional medical judgment and licensure.
