NHA Certified Clinical Medical Assistant (CCMA)Clinical Patient CareHard
A medical assistant is providing discharge instructions to a patient who just had a cast applied to their lower arm. Which of the following instructions is most critical to prevent complications?
- AElevate the affected limb above heart level.
- BKeep the cast dry at all times.
- CApply ice packs directly to the cast for pain relief.
- DDo not insert anything into the cast to scratch an itch.
Show answer & explanationAnswer & explanation
Correct answer: A. Elevate the affected limb above heart level.
Elevating the affected limb above heart level, especially for the first 24-48 hours, is crucial to reduce swelling and prevent compartment syndrome, which is a severe complication. While keeping the cast dry and not inserting objects are important, they relate to cast integrity and skin irritation, respectively, and are generally less immediately critical than preventing severe swelling.
Why the other options are wrong
- B. Keeping the cast dry is important for maintaining its integrity and preventing skin irritation/infection, but it's not the most critical instruction for immediate complication prevention.
- C. Applying ice packs directly to the cast is generally not recommended as it can damage the cast material or cause skin injury without proper protection.
- D. Not inserting objects into the cast is important to prevent skin breakdown, infection, and nerve damage, but preventing severe swelling (addressed by elevation) is more immediately critical for preventing major complications.
