Vitamins prenatal

One year later, HT comes to you and excitedly states that she is pregnant. She just saw her obstetrician, who started her on a prenatal vitamin. She states that she has felt very well since her LT4 was started and that she is amazed at how much better she feels ("I didn t know how bad I felt until I started the thyroid medicine"). The most recent TSH determination, obtained 6 months ago, was 1.5 milliunits/L (normal 0.5-2.5 milliunits/L). Her current LT4 dose is 88 mcg/day.

Folic acid supplements are given to pregnant women to decrease the risk of neural tube defects such as spina bifida. Prenatal vitamin preparations that contain higher concentrations of folic acid must be dispensed under a health care worker s guidance because high folate intakes can mask the symptoms of pernicious anemia. 

It s never too early to start taking a prenatal vitamin when attempting to conceive. If one makes you feel nauseated, keep trying others, as there is a large variety on the market. But be absolutely sure to take one that includes the maximum daily recommended dose of folic acid (important for helping prevent neural tube defects and spina bifida). Organic prenatal vitamins do exist. The main differences between these and more conventional vitamins is that they re vegetarian and include no filler, artificial color, or flavor. 

Get on a prenatal vitamin. There are organic versions that are dye-free and contain fewer and more natural ingredients. Just make sure they have the right dosages of everything you need, especially folic acid to help prevent neural tube defects. 

Take your prenatal vitamin right before bed to avoid nausea, or try another brand if it doesn t help.

Iron poisoning results from the ingestion and absorption of excessive amounts of iron from iron tablets, multiple vitamins with iron, and prenatal vitamins. Different iron salts and formulations contain varying amounts of elemental iron (see Chap. 99). Generally, children s chewable vitamins are less likely to produce systemic iron poisoning due in part to lower iron content. 

Perchlorate salts are potent oxidizers and are used in solid propellants for rockets and missiles, fireworks, road flares, matches, and auto air bag inflation systems. They are also found in Ghilean fertifizers, a wide variety of foods including vegetables and cows milk, prenatal vitamins, and as a result of natural processes (Dasgupta et ai, 2005). Thus, it appears likely that perchlorate is a naturally occurring anion and is probably ubiquitous. 

Worldwide, milk, fish, eggs and meat have been consistently identified to be the most important natural food sources for iodine (Dahl et al., 2004 Girelli et al, 2004 Remer et al., 2006 Varo et al., 1982 Wenlock et al., 1982). Iodine is also obtained from dietary supplements. About half of prenatal vitamins and many multivitamins are supplanted with 100-200 pg per day, and iodine is often found in multi-mineral and multi-vitamin-and-multi-mineral preparations (Lee and Roper, 2004). In 1986, the National Health Interview Survey considered the use of vitamin and mineral supplements among a... 

It has been recommended that iodine be added to all prenatal vitamins (National Academy of Sciences, 2003) and that women receive 150pg iodine supplements daily during pregnancy and lactation (Becker et at, 2007 Zimmermann and Delange, 2004). 

Pregnant vegetarians and vegans are a population at particular risk of iodine deficiency and should use iodine-containing prenatal vitamins. 

The mother of a 2-year-old child calls the emergency department and reports that the child has swallowed a bottle of prenatal vitamins. Which question is most important for the nurse to ask the mother ... 

If the prenatal vitamins have iron, this is a life-threatening situation. The child can hemorrhage because of the ulcerogenic effects of unbound iron, causing shock. As few as 10 tablets of ferrous sulfate (3 g) taken at one time can be fatal within 12 to 48 hours. This is the most important question to ask to determine what treatment the child should have for the accidental overdose. 

Determining if the vitamins may have lost potency if they were purchased months ago is not as high a priority as determining if the prenatal vitamins have iron. 

Prenatal vitamins with iron are part of a pregnant woman s routine medications. Ferrous sulfate is pregnancy category A, which means it has been proved safe for the fetus. The nurse would not question administering this medication. 

The active forms of vitamin A that were associated with the defects are found in fortified breakfast cereals, liver, and some vitamin snpplements. Beta-carotene, a form of vitamin A that has not been linked to birth defects, is now nsed in many prenatal vitamin snpplements. Beta-carotene is a plant-based vitamin A source that is converted into an active form of vitamin A once ingested. 

Fig. 13.1 Prenatal vitamin supplement label indicates that 50 % of the 4,000 lU of vitamin A supplied by is beta-carotene, and the remainder is from vitamin A acetate thus, 50 % of the total vitamin A supplied or 2,000 lU would need to be considered toward the total of 10,000 lU considered to be toxic to the developing fetus...

X.R. is a 36-year-old Hispanic female gravida 1 para 0. Mrs. R. presented at 39 weeks with symptoms of spontaneous rupture of membranes, contractions every 3 to 4 minutes, and mid to low back muscular pain. She reported active fetal movements and sparse vaginal bleeding. During this pregnancy, she had no complications and gained 32 pounds. Mrs. R. had no significant medical history and her only medication was prenatal vitamins. 

An infant girl was bom at 37.5 weeks of gestation to a 34-year-old mother via emergent caesarean delivery for maternal preeclampsia. There was no maternal history of diabetes, excessive alcohol use or smoking, but a limited dietary intake of dairy products. She self-administered prenatal vitamins, but received no... 

TOXICITY (HYPERVITAMINOSIS K). The natural forms of vitamins K, and Kj have not produced toxicity even when given in large amounts. However, synthetic menadione and its various derivatives (formerly called K,) have produced toxic symptoms in rats and jaundice in human infants when given in amounts of more than 5 mg daily. Consequently, the U.S. Food and Drug Administration does not allow any menadione in any food supplements, including prenatal vitamin capsules. 

Lack of vitamin D in infants results in rickets even in the presence of a favorable Ca/P ratio in the diet. A pure prenatal vitamin D deficiency could probably lead to rickets in human fetuses, but it-is doubtful whether such cases ever occur. In the instances of congenital rickets reported by Maxwell, et al. (136,137,138) the maternal diets were deficient in vitamins, minerals and eneigy.
