True or False: A nose pinch test is a non-instrumental method to assess a child's velopharyngeal function.

The assertion is accurate because the nose pinch test is indeed a non-instrumental method used to assess a child's velopharyngeal function. This assessment involves pinching the child’s nostrils closed while they speak, which forces the child to produce sounds without nasal airflow. By doing so, the clinician can evaluate how well the velopharyngeal mechanism is functioning. If the child is able to produce the speech sounds clearly without nasal resonance when the nose is pinched, it suggests that the velopharyngeal valve is functioning properly. This method is straightforward and requires no special equipment, making it accessible for clinical assessments.

Other options are not applicable in this context because the nose pinch test does not rely on special equipment and is commonly used in clinical settings for this purpose.
