English: Western Pacific Ocean (Sept. 23, 2003) -- Hospital Corpsman 2nd Class Donna Sanderson from Lancaster, Calif., prepares serum cups for a lipids panel that is designed to test cholesterol levels in a patient’s blood aboard USS Nimitz (CVN 68). The Nimitz Carrier Strike Group and embarked Carrier Air Wing Eleven (CVW-11) are deployed to the Western Pacific, and will remain there during the maintenance period of the forward deployed USS Kitty Hawk (CV 63). U.S. policy is to maintain at least one operational carrier in the region to ensure a responsive defensive posture. U.S. Navy photo by Photographer’s Mate Airman Timothy F. Sosa. (RELEASED)
