Question 5

Answer 5

Percutaneous non-tunneled central
catheter
Peripherally inserted central catheter
(PICC)
Tunneled cuffed catheters/Implanted ports

• catheter tip placed in a small vein
• short term use
• NO cardiopulmonary, renal, or hepatic failure
• peripheral, midline, or midclavicular intravenous catheter

Question 7

central catheter osmolarity

Answer 7

allows for higher caloric PN formulation and therefore greater osmolarity
