According to documentation guidelines the most appropriate notation is

A) "1230 hours: Patient's vital signs taken."
B) "0700 hours: Patient drank adequate amount of fluids."
C) "0900 hours: Morphine given for lower abdominal pain."
D) "0830 hours: Increased IV fluid rate to 100 mL per hour."

Information within a recorded entry must be complete,containing appropriate and essential information.The notation "0830 hours: Increased IV fluid rate to 100 mL per hour" provides the time and action taken by the nurse,including the reason for doing so.The entry "1230 hours: Patient's vital signs taken" does not indicate what the patient's vital signs were.The entry "0700 hours: Patient drank adequate amount of fluids" does not provide the specific amount that the patient drank.Stating "adequate" is subjective,not objective.The notation "0900 hours: Morphine given for lower abdominal pain" does not indicate how the patient describes his or her pain or rates it on a pain scale for comparison later.It also does not indicate whether the patient's pain was in the lower left or lower right quadrant,or both.
