Question

A 3 year-old presents with profuse watery diarrhea for the past three days. The child vomited twice yesterday, but not today. On examination, the child is febrile, with pulse of 142, respiratory rate of 18, and blood pressure of 60/40 mmHg. The child is alert and responsive, with no focal findings. Which of the following is the most appropriate intervention? A. Antibiotic therapy B. Loperamide (Imodium) C. 3% normal saline IV infusion D. Oral rehydration

Answer 1

The most appropriate intervention for this child would be to provide them with 3% normal saline IV infusion. A fever and profuse watery diarrhea can be signs of dehydration, which is a serious condition and requires immediate medical attention. The child is also tachycardic and hypotensive, which is concerning for dehydration and requires prompt rehydration. Antibiotics may be helpful later in treatment, but the child's current condition requires rehydration first. Oral rehydration is not enough in this case, which makes IV rehydration necessary.
