5. Select the meaning of the highlighted word in this sentence: A mother called her healthcare provider to report she had discovered a 'node' on her child's upper arm.
Answer: A
A small rounded mass
In the context of the sentence, the word 'node' refers to a small rounded mass that can be felt or seen on the body. This is consistent with medical terminology, where a node often signifies an abnormal growth or lump.
A) A small rounded mass
This option accurately captures the meaning of 'node' as used in the medical context. Nodes are commonly described as small, rounded masses of tissue that can be indicative of various conditions, making this the correct interpretation.
B) Oozing blood
This option is incorrect as it describes a symptom or condition rather than a physical entity. 'Oozing blood' does not relate to the term 'node,' which specifically denotes a mass rather than a bleeding issue.
C) A blister
While a blister is a type of fluid-filled sac on the skin, it does not fit the definition of 'node.' Blisters are typically associated with skin damage or irritation rather than being a solid mass, making this option incorrect.
D) A reddened area
This option refers to a change in skin color that can be a symptom of inflammation or irritation, but it does not describe a physical mass like a node. Therefore, it does not accurately represent the term in question.
Conclusion
The correct answer, "A small rounded mass," precisely defines what a 'node' is in a medical context, distinguishing it from other options that describe symptoms or different types of conditions. All other choices fail to capture the specific nature of a node, reinforcing that A is the only correct interpretation of the term in this scenario.
