EMS is transferring a 4-day-old neonate patient from a small, rural ICU to an urban pediatric hospital. The patient is being treated for chronic diarrhea.

What is the benefit of administering isotonic crystalloid fluid boluses in the neonatal population with diarrhea?

a. Replace valuable electrolytes lost from diarrhea.
b. Intensify the force of left ventricular contractions.
c. Improve venous return to the right side of the heart.
