Final answer:
A healthcare professional observing a young patient crying would make an objective observation based on observable signs of crying, though understanding the reason behind the crying could involve subjective interpretation.
Step-by-step explanation:
When a healthcare professional observes a young patient crying, they make an objective observation. This type of observation is based on factual, measurable, and observable data that can be seen, heard, or measured, such as tears, sobbing sounds, or facial expressions associated with crying. While the act of crying itself is an objective observation, understanding the reason behind the crying may involve subjective observations since it requires an interpretation of the patient's emotional state, which is not directly observable.
