22. Select the meaning of the underlined word in this sentence: The nurse assisted the physician in removing the cast from the patient's arm.
Answer: A
Protective device
The term "cast" in the given context refers to a protective device used to immobilize a broken or injured limb, thus aiding in the healing process.
A) Protective device
This option accurately defines the term "cast," which is specifically designed to support and protect broken bones or injuries. It is a solid structure that keeps the affected area stable and prevents movement, making it essential for recovery.
B) Bandage
While a bandage is also used for medical purposes, it is generally a flexible strip of material used to cover wounds or hold dressings in place. It does not provide the same level of immobilization or support as a cast, making this option incorrect in this context.
C) Medicated salve
A medicated salve is a topical ointment used to soothe or treat skin conditions. It does not pertain to immobilization or protection of bones, thus making this option irrelevant to the meaning of "cast" in the sentence.
D) Sling
A sling is used to support an injured arm or shoulder but does not refer to the same comprehensive protective function as a cast. Therefore, while related to orthopedic care, a sling does not match the definition of "cast" in this context.
Conclusion
The correct answer, "Protective device," is definitively right as it precisely encapsulates the role of a cast in medical treatment. All other options fail to convey the specific function of immobilization and protection that a cast provides, making them unsuitable interpretations of the term in this context.
