C. Lutein
Lutein is an antioxidant that supports eye health but is not primarily used to reduce the risk of birth defects.

Similar Questions
The nurse is aware that vitamin B12 is absorbed in the:
A. Duodenum
The duodenum is the first part of the small intestine where a significant amount of digestion takes place, but vitamin B12 is primarily absorbed in the lower part of the small intestine, called the ileum.
B. Stomach
The stomach plays a role in releasing intrinsic factor, which helps in the absorption of vitamin B12, but the actual absorption occurs in the small intestine.
C. Small intestine
Vitamin B12 absorption primarily occurs in the lower part of the small intestine (ileum), facilitated by intrinsic factors.
D. Large intestine
The large intestine primarily absorbs water and electrolytes; it is not a site for vitamin B12 absorption.

A nurse is collecting data from a client who has an inadequate dietary intake of fiber. Which of the following findings should the nurse expect?
A. Brittle hair
Brittle hair is more associated with protein deficiencies or inadequate hydration rather than insufficient fiber intake.
B. Bleeding gums
Bleeding gums can be related to vitamin deficiencies (like vitamin C), poor oral hygiene, or gum disease but not primarily to inadequate fiber intake.
C. Constipation
Constipation is a common consequence of inadequate fiber intake, as fiber helps add bulk to stools, promoting regular bowel movements.
D. Memory loss
Memory loss is not typically a direct result of insufficient fiber intake; it may be associated with various neurological or age-related conditions.

The nurse is aware that vitamin B12 is absorbed in the:
A. duodenum
The duodenum is the first part of the small intestine but is not the primary site for vitamin B12 absorption. It's primarily absorbed in the lower part of the small intestine called the ileum.
B. stomach
While the stomach plays a role in releasing intrinsic factor that aids in B12 absorption, the actual absorption occurs in the small intestine, particularly the ileum.
C. small intestine
Vitamin B12 absorption primarily occurs in the lower part of the small intestine, facilitated by intrinsic factors.
D. large intestine
The large intestine is mainly responsible for water absorption and electrolyte balance, not vitamin B12 absorption.
