Select the meaning of the underlined word in the sentence.
The lab technician wore gloves as a precaution.
A.
Rule
B.
Preventive measure
C.
Routine procedure
D.
Habit
The Correct answer and Explanation is:
The correct answer is B. Preventive measure.
Explanation:
In the context of the sentence, the term “precaution” refers to actions taken in advance to prevent harm or adverse outcomes. The lab technician wearing gloves is an example of taking a preventive measure to protect both themselves and the samples they are handling from contamination or exposure to potentially harmful substances.
Understanding “Precaution”:
The word “precaution” derives from the Latin “prae” (before) and “cautio” (caution). It encompasses the idea of being cautious and prepared to mitigate risks. In healthcare and laboratory settings, precautions are crucial for maintaining safety standards. They are proactive steps designed to prevent accidents, infections, or errors.
Why “Preventive Measure” Fits Best:
Option B, “Preventive measure,” aligns perfectly with the idea of a precaution. Wearing gloves is a common practice to avoid direct contact with pathogens, chemicals, or other hazardous materials. This is particularly important in laboratories, where the risk of exposure is heightened. By taking this precaution, the technician minimizes the likelihood of contamination, thus ensuring a safer working environment.
Comparison with Other Options:
- A. Rule: A rule is a prescribed guide for conduct or action. While wearing gloves can be mandated by rules, the word “precaution” implies a more proactive stance rather than simply following a guideline.
- C. Routine procedure: A routine procedure refers to an established way of doing things regularly. While wearing gloves may be routine, “precaution” emphasizes the intent to prevent risk rather than the regularity of the action.
- D. Habit: A habit suggests a behavior that is done automatically, often without conscious thought. Precautions are deliberate actions taken for safety rather than unconscious behaviors.
In summary, “precaution” in this context means a preventive measure, underscoring the importance of safety in laboratory practices.
