What instruction should a nurse give before discharging a client receiving a plaster cast?

The most appropriate instruction for a nurse to provide before discharging a client with a plaster cast is to notify the provider if numbness, swelling, or coldness occurs. This guidance is crucial as these symptoms can indicate complications such as compartment syndrome or inadequate circulation, which could lead to serious outcomes if not addressed promptly. Numbness may suggest nerve compression, while swelling may indicate increased pressure within the cast or surrounding tissues, and coldness can be a sign of reduced blood flow.

Monitoring for these signs is important in a patient with a cast, as the structure can limit circulation and contribute to potential complications. Educating the patient to look out for these symptoms ensures they maintain awareness of their condition and understand when to seek medical attention, which promotes safety and prevents complications after discharge.

In contrast, allowing weight-bearing after just one hour is generally not advisable, as it can lead to undue stress on the newly applied cast and potentially compromise healing. The cast does not need to be removed in three days unless there is a problem, as it typically remains in place for several weeks depending on the injury. Applying ice directly to a plaster cast is also discouraged because moisture can compromise the integrity of the cast and skin underneath, leading to irritation or skin conditions.
