The Parent of an Infant with Gastroesophageal Reflux Asks the Nurse

The parent of an infant with gastroesophageal reflux asks the nurse why the specialist wants the infant on omeprazole (Prilosec) , which is not covered by her health maintenance organization (HMO) , instead of metoclopramide (Reglan) , which is covered. Which of the following is the nurse's best answer?

A) "Physicians tend to prescribe the same drug regardless of what the HMO covers, because they understand that drug best."
B) "You need to let your doctor know that your HMO will not cover this drug and tell the doctor you need a prescription for Reglan."
C) "Prilosec has become a preferred choice for infants because current research does not support the use of Reglan in managing the symptoms of gastroesophageal reflux in infants and children."
D) "Reglan is a less-expensive drug and has only slightly more side effects, so talk with the pharmacist and see if you would be better off with Reglan."
