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

Rationale

Protective device

In the context of medical treatment, a "cast" refers to a rigid protective device used to support and immobilize broken bones during the healing process. It is typically made of materials such as plaster or fiberglass and is applied to the affected area to ensure proper alignment and protection of the bone.

A (Protective device) CORRECT

The term "cast" in this sentence refers to a protective device used in medicine to stabilize and protect a broken bone while it heals. This device is usually rigid and encompasses the injured limb to ensure the bone remains in the correct position.

B (Bandage) YOUR ANSWER

A bandage is a strip of material used to support or immobilize a part of the body or to hold a dressing in place. Unlike a cast, a bandage is not rigid and does not provide the same level of immobilization for broken bones.

C (Medicated salve) YOUR ANSWER

A medicated salve is an ointment applied to the skin to heal or protect it. It does not serve the function of immobilizing or protecting broken bones, as a cast does.

D (Sling) YOUR ANSWER

A sling is a piece of fabric used to support an injured arm or shoulder. It provides support but not the rigid immobilization required to protect a healing bone, which is the primary function of a cast.

Conclusion

In medical terminology, a "cast" refers specifically to a rigid protective device used to aid in the healing of broken bones by immobilizing the affected area. This distinguishes it from other items like bandages, salves, or slings, which serve different purposes in medical care. The sentence clearly indicates the use of a cast as a protective method, highlighting its role in the patient's treatment.
