INP 400 Final Exam Questions with Complete Solutions (Latest 2025) Fracture Healing Stages (5) - Correct Answers ✅1.Hematoma formulation
- fibrocartilage formation
- callous formation
- ossification
- remodeling and consolidation
Fracture Healing Stage 1 - Correct Answers ✅**hematoma
formation:
-Immediately after a fracture, bleeding and edema occur -In 48 to 72 hours, a clot or hematoma forms between the two broken ends of the bone Fracture Healing Stage 2 - Correct Answers ✅**granulation
(fibrocartilage formation):
-3 to 7 days -Hematoma that surrounds fracture does not reabsorb, as it does in other parts of the body -Instead, other tissue cells enter the clot, and granulation tissue replaces the clot -The tissue then forms a collar around each end of the broken bone, gradually becoming firm and forming a bridge between the two ends 1 / 3
INP 400 Final Exam Questions with Complete Solutions (Latest 2025) Fracture Healing Stage 3 - Correct Answers ✅**callus
formation :
-Within 1 to 4 weeks after injury, granulation tissue changes into a callus, which is made up of cartilage, osteoblasts, calcium, and phosphorus.-The callus is larger than the diameter of the bone and serves as a temporary splint Fracture Healing Stage 4 - Correct Answers
✅**ossification:
-Within 3 weeks to 6 months after the break, a permanent bone callus, known as woven bone, forms -During this stage the ends of the broken bone begin to knit Fracture Healing Stage 5 - Correct Answers
✅**consolidation and remodeling:
-Consolidation occurs when the distance between bone fragments decreases, then closes -During bone remodeling, immature bone cells are gradually replaced by mature bone cells -Excess bone is chiseled away by stress to the affected part from motion, exercise, and weight bearing -Bone then takes on its original shape and size Fracture - Correct Answers ✅A disruption or break in the continuity of the structure of bone 2 / 3
INP 400 Final Exam Questions with Complete Solutions (Latest 2025) Stable fracture - Correct Answers ✅occurs when a piece of the periosteum is intact across the fracture and either external or internal fixation has rendered the fragments stationary -not displaced after accident/immobilization -transverse, spiral, greenstick Unstable fracture - Correct Answers ✅a fracture grossly displaced during injury, thus a site of poor fixation. (oblique or comminuted fractures) Fracture Signs - Correct Answers ✅-Immediate localized pain -decreased Function -Inability to bear weight or use affected part -Guarding -May not be accompanied by obvious bone deformity Fracture Treatment - Correct Answers ✅-Anatomic realignment of bone fragments (reduction) -Immobilization to maintain alignment -Restoration of normal function
