Which of the following types of fractures involves the bone breaking into multiple pieces?

Hypertrophic nonunion occurs when there is excessive callus formation at the fracture site, but the bone ends fail to unite. This can lead to persistent pain and limited function.

a. Nonunion: Nonunion occurs when the fractured bone fails to heal and fuse together, but it does not involve excessive callus formation.
b. Malunion: Malunion refers to a fracture that heals in an incorrect position or alignment, and it is not directly related to excessive callus formation.
c. Delayed union: Delayed union refers to a fracture that takes longer than usual to heal, and it is not specifically characterized by excessive callus formation.

Before moving or handling the affected limb, the nurse must assess for any signs of neurovascular compromise, such as changes in pulses, capillary refill, sensation, and motor function. This assessment helps identify potential vascular or nerve injuries and guides appropriate care to prevent complications.

a. Explaining the importance of immobilization to the patient is important but is not directly related to assessing for neurovascular compromise before moving the limb.

b. Applying a splint or cast to the affected limb is typically done after the initial assessment and diagnosis of the fracture, not before handling the limb.

d. Administering analgesics for pain relief is important, but it does not directly relate to assessing for neurovascular compromise before moving the limb.
