Twelve dietary iron tablets were analyzed by the gravimetric procedure in Section 1-4 and the final mass of Fe203 (FM 159.688) was 0.2774 0.00 lx g. Find the average mass of Fe per tablet. (Relative uncertainties in atomic masses are small compared with relative uncertainty in the mass of Fe203. Neglect uncertainties in atomic masses in this problem.)...

Allergies and any other medicines should be enquired about before explaining that Mrs WL should take one tablet three times a day. Explain what side-effects she may experience as above and inform her that she can take the tablets with food if the side-effects are troublesome. It is very important to warn patients that their stools may be darkened (almost black). Compliance is often an issue with iron tablets and good counselling can aid this. 

Qll Iron preparations are a common cause of accidental poisoning in very young children, who may mistake iron tablets for sweets. How is acute iron toxicity treated ... 

Our third demonstration involves the decreased ability for a solution to evaporate when compared to the plain solvent. Once again, this property, called vapor-pressure lowering, does not depend on the chemical nature of the solute but simply on how much of the solute is dissolved in the solvent. Take two spoons and crush three aspirin tablets. Take two small, clear cups and add the crushed aspirin to one of the cups. Pour a half cup (120 milliliters) of rubbing alcohol into each. It is necessary to have the solution levels the same. Swirl the aspirin-alcohol cup to mix the contents. (Some may remain undissolved.) Label the cups to show which one contains the aspirin and then set both cups in a similar environment so that they both get the same amount of heat, air currents, and so forth. Side by side on a counter works well. In about an hour, you should observe an obvious difference in the levels in the cups. Although solvent is evaporating from both cups, it is evaporating more slowly from the aspirin cup. The same effect can be observed for vitamin pills or iron tablets dissolved in alcohol. Thus, it is the presence of the solute that causes the effect, not the nature of the solute.

Acute poisoning of children who have taken iron tablets found in the medicine cabinet or elsewhere in the home has repeatedly been reported. The tablets, often attractively coloured and sugar-coated, are readily assumed to be confectionery. 

The number of young children who have accidentally swallowed iron has more than doubled since 1986, since when more than 110 000 children under 6 years who accidentally swallowed iron tablets were reported to poison control centers. Many of the children were hospitalized and at least 33 died. The children who died had swallowed as few as five to as many as 98 tablets. In some cases, toddlers found tablets within their reach in uncapped or loosely capped containers. In other cases a young child managed to open a container. In 1995 the number of cases of unintended ingestion of iron by children was estimated at some 22 000 in the USA alone (51). Acute toxicity is associated with free radical formation. Emetics, gastric lavage, and even surgery may be called for to remove the excess. 

The Consumer Product Safety Commission, which regulates child-resistant packaging for household substances, requires such packaging for any oral iron product that contains 250 mg or more iron per container. In addition, the FDA s proposed regulations would require manufacturers to wrap iron tablets and capsules containing more than 30 mg per dosage unit in individual units, such as in blister packs.

Abdominal radiograph to detect solid iron tablets in gastrointestinal tract... 

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. 

An abdominal radiograph (Fig. 10-8) may help to confirm the ingestion of iron tablets and indicate the need for aggressive gastrointestinal evacuation with whole-bowel irrigation. An abdominal radiograph is most useful within 2 hours of ingestion. The visualization... 

Iron poisoning often is not recognized as a potentially serious problem by parents or victims until symptoms develop, and thus valuable time to institute treatment is lost. Parents should be made aware of the potential risks and asked to observe basic poison prevention measures. Many chewable vitamins with iron are shaped like animal or cartoon characters that can be attractive to children and can lead to poisoning. Some hard-coated iron tablets resemble candy-coated chocolates and are confused easily by children. Based on these considerations and the frequency of this poisoning, iron tablets are packaged in child-resistant containers. 

Young children are gustatory explorers. Among the compounds responsible for toxicity in youngsters under the age of 3 years are three items commonly found in households with "tots" aspirin, acetaminophen (people know about Reye sl), and supplementary iron tablets. 

Accidental ingestion of iron tablets by children is common and may be life threatening. Symptoms include nausea and vomiting, abdominal pain, diarrhoea and haematemesis. In severe cases, hypotension, liver damage and coma can result. Serum iron is increased and transferrin is saturated (>70%).
