<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 3-year-old boy is brought to the emergency department with a history of unintentional ingestion of seawater while swimming in the sea. The amount of seawater ingested is not known. There is no history of vomiting. On physical examination, the boy appears confused and is asking for more water to drink. His serum sodium is 152 mmolL 152 mEqL. Which of the following changes in volumes and osmolality of body fluids are most likely to be present in this boy?? A: Decreased ECF volume, unaltered ICF volume, unaltered body osmolality, B: Decreased ECF volume, decreased ICF volume, increased body osmolality, C: Increased ECF volume, unaltered ICF volume, unaltered body osmolality, D: Increased ECF volume, increased ICF volume, decreased body osmolality, E: Increased ECF volume, decreased ICF volume, increased body osmolality,  <response>: This is a question about fluid and electrolyte imbalances in a child who has ingested seawater. The key points in the stem are:- 3 year old boy ingested unknown amount of seawater while swimming- No vomiting - Appears confused and asking for more water to drink- Serum sodium is high at 152 mmolLThe ingestion of seawater, which has a very high salt content, can lead to hypernatremia high sodium levels. The lack of vomiting means the seawater was likely absorbed. The confusion and increased thirst indicates the boy is dehydrated. The high serum sodium indicates the extracellular fluid ECF volume is likely contracted due to the osmotic effect of the absorbed seawater. This would pull water out of the cells into the ECF, decreasing the intracellular fluid ICF volume. The increased osmolality of the ECF due to the excess sodium from seawater would also increase the overall body osmolality.E: Increased ECF volume, decreased ICF volume, increased body osmolality
