A nurse is teaching a client who is trying to conceive.
Which of the following should the nurse instruct the client to increase in her diet to prevent a neural tube defect?
Iron.
Calcium.
Folate.
Zinc.
The Correct Answer is C
Choice A rationale:
Iron is essential for healthy blood, but it is not specifically associated with preventing neural tube defects. Iron supplementation is crucial during pregnancy to prevent iron-deficiency anemia.
Choice B rationale:
Calcium is essential for bone health, but it is not directly related to preventing neural tube defects. Adequate calcium intake is vital, especially during adolescence and pregnancy, to support bone development and maintenance.
Choice C rationale:
"Folate." This is the correct answer. Folate, also known as vitamin B9, is crucial for preventing neural tube defects. Adequate folate intake, especially before and during early pregnancy, can significantly reduce the risk of neural tube defects in newborns. The normal recommended dietary allowance (RDA) for folate is 400 micrograms per day for adults.
Choice D rationale:
Zinc is a mineral important for immune function and wound healing but is not specifically associated with preventing neural tube defects. Adequate zinc intake is essential for overall health, but it is not a primary nutrient targeted for neural tube defect prevention.

No explanation
Correct Answer is A
Explanation
Choice A rationale:
After a total gastrectomy, the client lacks the intrinsic factor necessary for the absorption of vitamin B12 in the terminal ileum. Therefore, vitamin B12 supplementation is essential to prevent pernicious anemia, a condition caused by vitamin B12 deficiency. The absence of intrinsic factor hinders the absorption of vitamin B12 from dietary sources, making it necessary to provide this vitamin through injections or high-dose oral supplements. Vitamin B12 supplementation is a standard practice following a total gastrectomy.
Choice B rationale:
Ranitidine is a histamine-2 (H2) receptor antagonist used to reduce stomach acid production. It is not directly related to vitamin B12 deficiency and is not typically prescribed following a total gastrectomy. Vitamin B12 supplementation, on the other hand, addresses the specific deficiency caused by the absence of intrinsic factor.
Choice C rationale:
Vitamin K is essential for blood clotting and bone health. However, it is not the primary concern following a total gastrectomy. Vitamin B12 deficiency leading to pernicious anemia is the major focus of post-gastrectomy supplementation. While vitamin K may be important for overall health, it is not the immediate priority in this scenario.
Choice D rationale:
Metoclopramide is a medication used to treat gastrointestinal disorders, including gastroparesis and gastroesophageal reflux disease (GERD). It does not directly address the vitamin B12 deficiency resulting from the absence of intrinsic factor. Vitamin B12 supplementation is specifically indicated to prevent pernicious anemia in this context.
