A nurse is caring for a newborn who is receiving breast milk and supplemental vitamin D drops daily.
The nurse knows that vitamin D supplementation is necessary for breastfed infants because:
Breast milk does not contain enough vitamin D for bone health
Breast milk interferes with vitamin D absorption from sunlight
Breast milk increases vitamin D excretion in urine
Breast milk inhibits vitamin D synthesis in the liver
The Correct Answer is A
Breast milk does not contain enough vitamin D for bone health. Vitamin D is needed to support healthy bone development and to prevent rickets, a condition that causes weak or deformed bones. Breast milk alone does not provide infants with an adequate amount of vitamin D. The Dietary Guidelines for Americans and American Academy of Pediatrics recommend breastfed and partially breastfed infants be supplemented with 400 IU per day of vitamin D beginning in the first few days of life.
Choice B is wrong because breast milk does not interfere with vitamin D absorption from sunlight. However, reducing sun exposure is important for preventing skin cancer, and other factors such as clothing, air pollution, and skin type can also decrease the amount of vitamin D a person can make from sunlight.
Choice C is wrong because breast milk does not increase vitamin D excretion in urine.
Vitamin D is a fat-soluble vitamin that is stored in the body and not easily lost in urine.
Choice D is wrong because breast milk does not inhibit vitamin D synthesis in the liver. Vitamin D is synthesized in the skin from exposure to sunlight, and then activated in the liver and kidneys to its active form.
Breast milk does not affect this process.
