Why are children more susceptible to the toxic effects of lead exposure? - correct answer 1.
Children have an increased hand-to-mouth behavior and thus prone to putting objects found in
their environment into their mouths.
2. The blood-brain barrier in children is immature during fetal development, contributing to
greater accumulation in the developing brain.
3.Infant absorption of lead is greater than adults. In adults, the body burden of lead is found in
bone. In children, growth results in a rapid turnover in skeletal bone causing a continuous
leaching of lead into the bone.
4. In cases of compromised nutrition, where dietary intake of iron and calcium is insufficient,
children are more likely to have elevated lead levels.
Discuss the nutritional implications in chronic alcoholism. - correct answer 1. Major nutritional
deficiencies associated with alcohol abuse include those of magnesium, vitamin B6, thiamine,
folic acid and phosphorus.
2. Folic acid deficiency becomes especially serious when alcohol is consumed during pregnancy
and may contribute to fetal alcohol syndrome.
3. Thiamine deficiency results in major neurologic sequele.
4. Increased risk of head and neck cancers
Discuss mechanisms of cell injury related to chronic alcoholism - correct answer 1. Protein
transport malfunctions
, 2. Increased intracellular cellular water
3. Decreased mitochondrial fatty acid oxidation
4. Excessive membrane rigidity
5. Liver cell necrosis
What are the sources of mercury exposure? - correct answer Natural geologic sources, vehicle
emissions, consumer products, industrial waste, and landfills and disposal sites.
-Dental Amalgam
-Some vaccine preservatives
-Food products (rice)
-terrestrial and marine animals, some which are consumed by humans
Why has air pollution become a leading cause of morbidity and mortality? - correct answer
Unhealthy air quality and pollution has contributed to premature deaths such as heart attacks,
stroke, cancer and chronic lung disease.
Give examples of intentional and unintentional asphyxia in the US - correct answer Four
categories of asphyxia: suffocation, strangulation, chemical asphyxiation and drowning.
Unintentional:
1. C02, cyanide, methane
2. Choking
3. Airway swelling
Intentional:
1. Strangulation - Although ligature can be accidental
