A nurse is teaching a newly licensed nurse about the differences between a plaster cast and a synthetic cast. Which of the following information should the nurse include in the teaching?

"Drying time is prolonged with a synthetic cast."

"A synthetic cast is lighter."

"A plaster cast weighs less."

"Application of a plaster cast requires specialized equipment."

Answer and Explanation

The Correct Answer is B

Choice A reason: This statement is incorrect. Synthetic casts typically dry much faster than plaster casts. Plaster casts can take 24 to 48 hours to fully harden, while synthetic casts made from materials like fiberglass or plastic can harden within a few hours.

Choice B reason: This is the correct statement. Synthetic casts are indeed lighter than plaster casts. They are made from materials like fiberglass, which is lighter than the traditional plaster of Paris used in plaster casts.

Choice C reason: This statement is incorrect. Plaster casts are generally heavier than synthetic casts. The weight of a cast can be an important consideration, especially for children or for those who may have difficulty managing a heavier cast.

Choice D reason: This statement is incorrect. Both plaster and synthetic casts require specialized equipment for application, but it is not specific to plaster casts. The application involves similar steps for both types, including the use of a stockinette, padding, and then the casting material itself.

A. Apply heat for 10 minutes every hour. B. Sleep in a side lying position with flexed knees. C. Avoid prolonged sitting. D. Use padded shoe insoles. E. Sleep on a soft matress

Correct Answer is ["A","B","C"]

Explanation

Choice A: Apply heat for 10 minutes every hour
Applying heat can help to relax the muscles and relieve tension, which can reduce pain. Heat therapy increases blood flow, which can aid in healing and reduce stiffness.

Choice B: Sleep in a side lying position with flexed knees
Sleeping in a side-lying position with flexed knees can help to maintain the natural curve of the spine and reduce strain on the back muscles. It's also recommended to use a pillow between the knees for additional support.

Choice C: Avoid prolonged sitting
Prolonged sitting can put pressure on the discs in your lower back and cause or exacerbate pain. It's recommended to take regular breaks to stand up and move around.

Choice D: Use padded shoe insoles
While padded shoe insoles can provide comfort and support for some people, there's no strong evidence to suggest that they can help to prevent or relieve back pain.

Choice E: Sleep on a soft mattress
Contrary to popular belief, a soft mattress may not be the best choice for people with back pain. A mattress that's too soft can cause your back to sink into the mattress, leading to poor sleep posture and discomfort. It's generally recommended to choose a mattress that provides good support and maintains the spine's natural alignment.
