Editing Maternal and Newborn Nursing – LPN Practice Questions (section)

==Question 13==
An LPN is reinforcing formula-feeding teaching with a mother. Which statement indicates a need for further teaching?
# "I will hold my baby semi-upright and keep the nipple full of formula."
# "I can add extra water to make the formula last longer."
# "I will never heat the bottle in the microwave."
# "I will throw away formula left in the bottle after a feeding."

'''Answer:''' 2 (B). "I can add extra water to make the formula last longer."

''Rationale:'' Overdiluting formula causes inadequate calorie and protein intake and can cause '''water intoxication with hyponatremia and seizures'''; underdiluting stresses immature kidneys with an excessive solute load. Formula is mixed exactly as the manufacturer directs. If cost is the underlying concern, the nurse reports it so the family can be connected with assistance programs. Options 1, 3, and 4 are correct: semi-upright positioning with a full nipple reduces air swallowing and choking risk, microwaving creates uneven hot spots that can burn the mouth, and leftover formula is discarded because saliva contaminates it with bacteria.
