Select the meaning of the highlighted word in this sentence: The nurse assisted the physician in removing the 'cast' from the patient's arm.

Rationale

Protective device

In this context, "cast" refers to a rigid protective device used to support and immobilize a broken bone as it heals. This definition aligns with typical medical usage where a cast is applied to stabilize a fracture and ensure proper alignment during recovery.

A (Protective device) CORRECT

A cast is indeed a protective device, typically made of plaster or fiberglass, used in medical settings to immobilize a fractured limb. It is applied around the injured area to prevent movement and facilitate the healing process of bones.

B (Bandage) YOUR ANSWER

A bandage is a flexible strip of material used to support a medical dressing or to provide support to a limb or joint. Unlike a cast, a bandage does not generally provide immobilization necessary for bone healing, as it is not rigid or supportive enough to stabilize a fracture.

C (Medicated salve) YOUR ANSWER

A medicated salve refers to an ointment or cream applied to the skin for therapeutic purposes, often to soothe or heal a wound or rash. This term is unrelated to the function of a cast, which is meant for structural support rather than topical treatment.

D (Sling) YOUR ANSWER

A sling is a supportive device used to keep an injured arm or shoulder in place, typically made of fabric. While a sling can provide some support, it is not rigid and does not immobilize like a cast, making it unsuitable for stabilizing broken bones.

Conclusion

The word "cast" in this sentence specifically refers to a protective device used to immobilize and support a broken bone, distinguishing it from other medical items such as bandages, salves, or slings. The rigidity and immobilization properties of a cast make it uniquely suited for aiding the bone healing process, setting it apart from these other supportive or therapeutic items.
