42. Select the meaning of the highlighted word in this sentence: The nurse assisted the physician in removing the 'cast' from the patient's arm.
Answer: A
Protective device
In the context of the sentence, the highlighted word 'cast' refers to a protective device that immobilizes a limb to promote healing after a fracture or injury.
A) Protective device
This option is correct as a 'cast' serves specifically to protect and support a broken bone while it heals. It is typically made from materials like plaster or fiberglass, forming a rigid structure around the injured area.
B) Bandage
While a bandage is used to cover and protect wounds, it does not provide the same level of immobilization or support as a cast. Therefore, this option is incorrect in the context of the sentence.
C) Medicated salve
A medicated salve is a topical treatment meant for application on the skin, primarily for soothing or healing purposes. It does not relate to the concept of immobilizing a limb, making this option incorrect.
D) Sling
A sling is a device used to support an injured arm, but it does not provide the same comprehensive immobilization as a cast. Hence, this option does not accurately capture the meaning of 'cast' in the sentence.
Conclusion
The correct answer, 'protective device,' accurately reflects the primary function of a cast in medical practice as it immobilizes and protects an injured limb. All other options fail to encompass the specific role of a cast, either serving different purposes or lacking the necessary support and protection associated with casts.
