Rationale: Meconium is the term used to describe the first stool of a newborn. This stool is black and tarry in appearance. Meconium is made up of materials ingested by the fetus while in the uterus, such as mucus, amniotic fluid, and cells shed from the stomach and intestines.

Rationale: Option A, "Let him know it is all right to cry," is the most appropriate intervention for a four-year-old like Brian who appears to be upset by hospitalization. Acknowledging and validating his emotions, including the possibility of crying, is important for his emotional well-being. By letting Brian know it is okay to express his feelings, he can feel supported and understood during a potentially difficult time. It is crucial for children to feel that their emotions are valid and accepted, promoting their emotional resilience and coping skills. This approach fosters trust and comfort, helping Brian navigate his emotions in a healthy way.

Eliciting the startle reflex) are not suitable for screening the hearing of a 5-year-old child as they are either more applicable to adults or not as comprehensive and reliable as conventional audiometry when assessing hearing in children.
