NCLEX RN Practice Question # 942

Rationale. The preferred site for the administration of parenteral nutrition is to use a central catheter site to prevent damage to the peripheral areas.

A is incorrect—Parenteral nutrition is administered intravenously not in a PEG tube site; tube feedings are reserved for PEG tube sites. B is incorrect—TPN is an intravenous form of feeding a client and an NG tube goes directly to the stomach, which requires tube feeding solutions. D is incorrect—Placing a high concentration of glucose in a peripheral site will irritate the vein and can cause damage to the client’s surrounding tissues. TPN with greater than 10% glucose should use a central site.
