What should the nurse instruct an adolescent with a fiberglass arm cast regarding showering?

Instructing an adolescent with a fiberglass arm cast regarding showering should include the use of a plastic bag to protect the cast from water. Fiberglass casts are water-resistant but not completely waterproof, so while they can tolerate brief exposure to moisture, it’s safer to minimize direct water contact. Covering the cast with a plastic bag while showering prevents water from compromising the integrity of the cast and reduces the risk of skin irritation and potential complications such as infection.

This method supports the healing process by ensuring that the cast remains in proper condition and that the skin underneath does not become wet, which could lead to discomfort or complications. Other strategies like towel drying or avoiding all water exposure might not be practical or comfortable for adolescents who are accustomed to regular bathing. Similarly, sponge baths might be less convenient and less hygienic, especially for older children and teens who may prefer normal showering routines. Using a plastic bag strikes a balance between maintaining hygiene and protecting the cast.
