Prior to administering pain medication to an adult postoperative client, what information should the practical nurse (PN) obtain? (Select all that apply.)

Prior to administering pain medication to an adult postoperative client, the practical nurse (PN) should obtain the following information: Time of last administration of pain medication: It is important to know when the client last received pain medication to ensure that the appropriate timing for the next dose is followed. Client's pain rating on a scale of 1 to 10: Assessing the client's current pain level helps determine the need for pain medication and the appropriate dose. Effectiveness of last pain medication administered: Evaluating the effectiveness of the previous pain medication helps determine if the current regimen is sufficient or if adjustments need to be made. Obtaining the height and weight of the client prior to admission and the history of pain medication use during the past year may not be directly relevant to the immediate administration of pain medication.
