Final answer:
Statement 4 - I need to isolate the infant for 48 hours after beginning the antibiotics.
Step-by-step explanation:
The statement that indicates a need for further instructions is 4. I need to isolate the infant for 48 hours after beginning the antibiotics. This statement is incorrect because there is no need to isolate the infant in this scenario. The infection is localized to the episiotomy site and poses no risk to the baby.
