Final answer:
The task of assisting a client who had a hip arthroplasty to a chair is most suitable for delegation to assistive personnel (AP) as it is within their scope of practice and does not require professional nursing judgment.
Step-by-step explanation:
The charge nurse is tasked with planning assignments and allocating tasks appropriate to each team member's qualifications and scope of practice. When assigning a task to an assistive personnel (AP), the charge nurse must ensure it does not require professional nursing judgment or the interpretation of patient data.
Of the options provided, the task most suitable for delegation to an AP is: a) Assisting a client who had a hip arthroplasty to a chair. This task falls within the AP's scope of assistance with activities of daily living and does not require in-depth clinical knowledge or critical decision-making. It is also within the AP's role to operate under the direct supervision of a registered nurse, ensuring that patient safety is maintained during the transfer.
The other tasks, such as instructing clients on the use of a glucometer, interpreting vital signs, and cleansing the site of a catheter, are more complex and require the professional knowledge and skill set of a licensed nurse. These tasks often involve patient education, clinical decision-making, or specific procedures that go beyond the role of assistive personnel and hence should not be delegated to them.
