Explanation

At 24 months, a toddler's key linguistic achievement is the use of two-word sentences, often called telegraphic speech (e.g., "want juice," "go outside").
This ability allows them to move beyond simply naming objects to actively communicating their needs, desires, and observations.
Their expressive vocabulary typically expands to 50-300 words, and their speech becomes about 50-80% intelligible to others.
This stage directly reflects the ability to verbalize needs, making it the most accurate description among the choices.

Option A: This is incorrect. A child typically understands the meaning of "no" by 12 months and can follow simple commands.
Option B: While a 24-month-old does understand the meaning of many words, this is not the best description of their developmental stage. This ability begins much earlier and is a prerequisite for, rather than the defining feature of, their current language skills.
Option D: The phase of continuously asking "Why?" is characteristic of a preschooler, typically starting around 3 years of age. It reflects a more advanced cognitive curiosity about the world.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Language development milestones in a toddler (24 months) as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in developmental surveillance. During well-child visits, assessing language milestones is essential for early identification of potential delays.
A key red flag at 24 months is the absence of two-word spontaneous phrases. This warrants a referral for a formal hearing and speech-language evaluation.
Nurses should educate parents on fostering language development by reading to their child, naming objects, engaging in conversation, and responding to their child's verbal attempts.

How to Approach the Question

First, identify the core of the question, which is to find the best description of language skills for a specific age: 24 months (2 years).
Recall the typical developmental milestones for a two-year-old. Focus specifically on language abilities.
Evaluate each option against these milestones:
Option A: Does a 2-year-old understand 'yes' and 'no'? Yes, they do. So, this is incorrect.
Option B: Do they understand words? Yes, but this starts much earlier. Is it the best description? Probably not.
Option C: Can they verbalize needs? Yes, using two-word phrases is a primary way they do this. This is a key skill at this age.
