A client's fracture is healing and compact bone is replacing spongy bone around the periphery of the fracture. This process characterizes what phase of the bone healing process?
Hematoma formation.
Remodeling.
Bony callus formation.
Fibrocartilaginous callus formation
The Correct Answer is B
Choice A rationale
Hematoma formation is the initial stage of fracture healing, where a blood clot forms around the fracture site, creating a foundation for subsequent healing phases.
Choice B rationale
Remodeling is the final phase of bone healing, where compact bone replaces spongy bone, restoring the bone's structure and function.
Choice C rationale
Bony callus formation involves the development of new bone (callus) around the fracture site, which eventually transitions to compact bone during remodeling.
Choice D rationale
Fibrocartilaginous callus formation is an earlier stage of fracture healing, characterized by the formation of a soft callus made of collagen and cartilage that stabilizes the fracture.

Correct Answer is A
Explanation
Choice A rationale
The parietal lobe is responsible for processing sensory information and spatial awareness, including proprioception (the sense of body position in space). Damage to the parietal lobe can affect these functions.
Choice B rationale
The temporal lobe is involved in processing auditory information and memory, not spatial awareness. Damage to this lobe would affect hearing and memory rather than proprioception.
Choice C rationale
The frontal lobe is associated with executive functions, such as decision-making, problem-solving, and motor control, but not primarily with spatial awareness. Damage to this lobe impacts cognitive and motor functions.
Choice D rationale
The occipital lobe is primarily responsible for processing visual information. Damage to this lobe affects vision rather than spatial awareness or proprioception.
Correct Answer is D
Explanation
Choice A rationale
Gently pressing the bones on the neck does not effectively test for neck rigidity, which is a common indicator of meningeal irritation or inflammation. This method may detect tenderness or bony abnormalities but not rigidity.
Choice B rationale
Moving the head toward both sides primarily assesses range of motion and flexibility. While reduced range of motion can be noted, this method doesn't specifically test for the resistance characteristic of neck rigidity.
Choice C rationale
Lightly tapping the lower portion of the neck to detect sensation tests for sensory nerve function but is not relevant to assessing muscle tone or rigidity, which is related to motor nerve and muscular response.
Choice D rationale
Moving the head and chin toward the chest is a proper technique to test for neck rigidity. This maneuver can elicit pain or resistance in cases of meningeal irritation, providing a reliable assessment for rigidity.
