Choice A rationale:

If the client states, "I can feel a crunching sensation when I touch the area," it suggests crepitus, which is a common clinical finding in fractures.

Crepitus is caused by the rubbing of bone fragments against each other.

However, it is not specific to closed fractures and can also occur in open fractures.

Therefore, it is not the most reliable indicator of a closed fracture.

Choice B rationale:

"My skin around the fracture is warm and red" is indicative of inflammation, which can occur in response to any type of injury, including fractures.

While warmth and redness may be present in closed fractures due to the inflammatory response, they are not specific to closed fractures and can also occur in open fractures or other injuries.

This symptom alone does not confirm a closed fracture.

Choice C rationale:

"I can't move my limb due to the pain" is a key clinical presentation expected in a client with a closed fracture.

Closed fractures typically result in severe pain, swelling, and loss of function in the affected limb.

The pain and immobility are due to the disruption of the bone and surrounding tissues without any open wound.

This presentation is highly characteristic of a closed fracture.

Choice D rationale:

"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.
