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

The nurse should instruct the patient to avoid placing any objects under the cast to prevent skin irritation, damage to the cast, and potential introduction of bacteria or contaminants.

a. Encouraging the patient to frequently remove the cast for skin care is not recommended, as it can compromise the cast's fit and function and increase the risk of complications.
b. Advising the patient to use a hairdryer on the cast to relieve itching is not recommended, as it can cause skin maceration and damage the cast.
d. Educating the patient to keep the cast exposed to air for prolonged periods is not recommended, as dirt and debris can get trapped inside the cast, increasing the risk of infection. The patient should follow the healthcare provider's instructions for cast care.

Checking peripheral pulses is an essential part of the nursing assessment for a patient with a suspected fracture, especially in the extremity near the fracture site. It helps monitor circulation and ensures adequate blood flow to the injured area.

b. Measuring blood pressure: Measuring blood pressure is part of the routine nursing assessment but is not specific to a suspected fracture.
d. Evaluating liver function: Evaluating liver function is not directly related to the assessment of a suspected fracture.
