A Nurse Is Preparing to Assist with the Insertion of a Groshong

A nurse is preparing to assist with the insertion of a Groshong catheter. The nurse refers to the instructions regarding the use of Groshong catheters in a nursing reference book. The nurse learns that Groshong catheters differ from other central venous catheters in that they:

A) have an open-ended tip with a three-position valve that stays open all the time.
B) have a chemical makeup that allows for minimal use of heparin for flushing.
C) have a closed-end tip with a three-position pressure-sensitive valve that stays closed when not in use.
D) are available only in single-lumen type.
