Final answer:
High flow rates of O2 in Respiratory Distress Syndrome can cause oxygen toxicity and potentially lead to Retinopathy of Prematurity, which is not listed among the choices provided.
Step-by-step explanation:
High flow rates of O2 delivered in Respiratory Distress Syndrome can cause oxygen toxicity. This toxicity can potentially lead to various complications, such as damage to the lungs and other organs. However, with regard to the choices provided and the potential risks associated with high oxygen flow in the context of RDS, the use of high concentrations of oxygen over a prolonged period can lead to Retinopathy of Prematurity (ROP), which is not an option in the given list. Thus, none of the provided choices (cardiac arrhythmias, hypothermia, hypoglycemia, dehydration) directly relate to the specific complications associated with high O2 flow rates in RDS. The content loaded into this response reflects current understanding of oxygen delivery in neonatal care for infants with Respiratory Distress Syndrome.
