NR 283 - FINAL EXAM FINAL EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED) All-important process that takes place in bone marrow Correct answer hematopoiesis Difference between red and yellow bone marrow Correct answer yellow (fatty) bone marrow replaces red bone marrow in the long bones. Where does hematopoiesis occur Correct answer red bone marrow Where is red bone marrow found in adults Correct answer -cranium -bodies of the vertebrae -ribs -sternum 1 -ilia. Osteoblasts Correct answer bone producing cells; generate new bone. Osteoclasts Correct answer bone resorbing cells; break down bone. Bone resorption Correct answer is the resorption of bone tissue, the process by which osteoclasts break down the tissue in bone and releases the minerals, resulting in the transfer of calcium from bone tissue to the blood. Osteoclasts perform bone resorption. Functions of skeletal muscle Correct answer -to facilitate body movement by muscle contraction -to maintain body position by continuing muscle tone -to stabilize the joints and prevent excessive movement 2 -to maintain body temperature by producing heat through muscle contraction Synovial fluid Correct answer the joint cavity or space between the articulating ends of the bones is filled with a small amount of synovial fluid, which facilitates movement. The synovial fluid prevents the articular cartilage on the two surfaces from damaging each other and also provides nutrients to the articular cartilage. Complete fracture Correct answer occurs when the bone is broken to form two or more separate pieces Incomplete fracture Correct answer the bone is only partially broken Open/compound fracture Correct answer results when the skin is broken; the bone fragments may be angled and protrude through the skin. 3 Closed fracture Correct answer the skin is not broken at the fracture site. Simple fracture Correct answer a single break in the bone in which the bone ends maintain their alignment and position Comminuted fracture Correct answer in which there are multiple fracture lines and bone fragments Compression fracture Correct answer common in the vertebrae, occurring when a bone is crushed or collapses into small pieces Impacted fracture Correct answer occurs when one end of the bone is forced or telescoped into 4 the adjacent bone; for example, the neck of the femur is crushed against the pelvis. Pathologic fracture Correct answer results from a weakness in the bone structure due to conditions such as a tumor or osteoporosis. The break occurs spontaneously or with very little stress on the bone. Stress fracture Correct answer result from repeated excessive stress, commonly in the tibia, femur, or second and third metatarsals.
