Pathophysiology of Fractures

  1. Fractures occur when the mechanical stress applied to a bone exceeds its strength. This can result in a partial or complete breakage of the bone.
  2. The healing process involves four stages: hematoma formation, cellular proliferation, callus formation, and remodeling.
  3. The body initiates an inflammatory response at the site of the fracture, leading to the formation of a hematoma.
  4. Osteoblasts and fibroblasts migrate to the fracture site and begin proliferating, laying down new bone and connective tissue.
  5. Over time, a callus forms, bridging the fracture and stabilizing the bone.
  6. Remodeling occurs as the callus is gradually replaced by mature bone tissue.

Questions on Pathophysiology of Fractures

Correct Answer is C

Explanation

"The bone is sticking out of my skin" is not consistent with a closed fracture but rather suggests an open fracture. In an open fracture, the bone pierces through the skin, leading to exposure to the external environment. This is a distinct clinical presentation from a closed fracture and requires immediate attention for infection control and wound care.

Correct Answer is D

Explanation

"You're correct; it's an incomplete fracture" is the most appropriate nursing response. This response validates the client's understanding of the fracture and provides accurate information. Greenstick fractures are indeed incomplete fractures where the bone is bent but not completely broken.

Correct Answer is B

Explanation

Initiating physical therapy immediately is not the immediate priority for a client with an open fracture complaining of intense pain. Physical therapy typically follows fracture stabilization, wound management, and pain control. It is essential to address the client's pain and wound care needs first.

Correct Answer is B

Explanation

Greenstick fractures are incomplete fractures seen in children and adolescents, typically involving long bones. They are not typically associated with compression fractures of the vertebrae, which are more commonly linked to osteoporosis. Questions

Correct Answer is B

Explanation

It's just a precaution; you can get the cast wet occasionally. Rationale: This response is incorrect and could lead to the patient misunderstanding the importance of keeping the cast dry. Getting the cast wet occasionally is not recommended, as it can weaken the cast and increase the risk of complications.

Proper nutrition doesn't really affect bone healing. Rationale: This response is inaccurate. Proper nutrition plays a significant role in bone healing, and it's essential for the nurse to educate the client about the importance of maintaining a balanced diet to support the healing process.

Advocating for safety measures in recreational areas. Rationale: This is a correct response. Advocating for safety measures in recreational areas, such as the use of protective gear, can help reduce the risk of fractures during recreational activities.

Blood clots are more common in open fractures, not closed ones. Rationale: This response is misleading. While open fractures may have a higher risk of infection, both open and closed fractures can potentially lead to blood clot formation due to immobility and damage to blood vessels.

The patient's social media usage patterns. Rationale: The patient's social media usage patterns are not relevant to the assessment of a suspected fracture and should not be a priority during the initial evaluation. Questions

<p>Evaluating the client&#39;s psychological state is important for holistic care but may not be a primary assessment when evaluating a suspected fracture.</p> <p>The priority in this context is to assess physical signs and symptoms related to the fracture and any potential complications.</p>
