|
|
do not use in lactation because it is excreted in breast milk
|
|
Nursing responsibilities of GI stimulants
|
Admin PO Reglan 30 min before each meal
Teach pts that intestinal colic may occur within 30 min not abnormal it will soon get better. Safety precautions (Parkinson's symptoms) If paralytic ileus, monitor bowel sounds (wont be any sounds until it is resolved) |
