13. Select the meaning of the quoted word in the sentence. The nurse assisted the physician in removing the 'cast' from the patient's arm.

Answer: A

Explanation:

Protective device

In the context of the sentence, 'cast' refers to a protective device used to immobilize and support a broken or fractured bone during the healing process.

A) Protective device

This option accurately defines 'cast' as it describes the primary function of a cast, which is to protect and support a limb that has been injured. A cast is typically made of plaster or fiberglass and is crucial in the treatment of fractures.

B) Medicated sleeve

This option is incorrect because a medicated sleeve does not represent the function or nature of a cast. While it may refer to a garment that delivers medication, it does not provide the same immobilization and protection that a cast does.

C) Sling

This option is also incorrect, as a sling is designed to support and immobilize an arm but does not provide the rigid support that a cast does. Slings are typically used for shoulder injuries or to support an arm that does not require full immobilization.

D) Bandage

This option is not correct since a bandage is primarily used for covering and protecting wounds rather than immobilizing a limb. While a bandage may be used in conjunction with a cast, it does not serve the same purpose of providing structural support.

Conclusion

The term 'cast' specifically refers to a protective device that immobilizes a limb, making option A the correct choice. The other options fail to accurately convey the definition and function of a cast, emphasizing the importance of understanding medical terminology in context.
