Oral

Pharmacology

Correct Answer:

i.v.

Description:

Since the child is seriously ill, a fast and more predictable action of the antibiotic is needed; a parenteral route of administration is appropriate. Moreover, oral dosing may be difficult in this case as the child is dull and irritable. Entering a vein for i.v. injection is relatively difficult in children, particularly in the presence of dehydration. Therefore, the antibiotic may be injected i.m. However, if an i.v. line is set up for rehydration, the antibiotic may be administered through the i.v. line.
