Answer to Question 1

B
Peripherally placed cannulas are inserted into veins of the hand and arm for short-term use (e.g., to restore fluid volume). Centrally placed catheters, peripherally inserted central catheters (PICCs), tunneled catheters, and implanted ports are venous access devices designed for long-term use.

Answer to Question 2

B
The nervous system also regulates posture. Posture requires coordination of proprioception and balance. Proprioception is the awareness of the position of the body and its parts and is dependent on impulses from the inner ear and from receptors in joints and ligaments.
