A client who is in the transition phase reports the narcotic pain medication they last received 3 hours ago has worn off. The client asks if they can have another dose of the narcotic. How should the nurse respond to the request?

"It is too early as the medication should be given only every 4 hours.”.

"I will get permission from your health care provider.”.

"Since it has been over 3 hours, you should be able to have more of the medication.”.

"Your phase of labor makes giving another dose unsafe for the fetus.”
