Final answer:
A patient should be positioned supine with the head slightly elevated, the arm abducted, and the head turned slightly to the opposite side of the catheter placement for non-tunneled catheter placement.
Step-by-step explanation:
When positioning a patient for non-tunneled catheter placement, it is important to ensure proper and stable placement of the catheter. The patient should be positioned in a supine position, meaning lying flat on their back, with the head slightly elevated. This helps to facilitate access to the insertion site and allows for better visualization during the procedure.
In addition to the supine position, the patient's arm should be abducted, meaning it is positioned away from the body. This allows for easier access to the subclavian or jugular veins, which are commonly used for non-tunneled catheter placement.
Lastly, the patient's head should be turned slightly to the opposite side of the catheter placement. This helps to provide better visualization and may aid in reducing the risk of complications during the procedure.
