Title: Ch. 4.1.2 Safety Quiz
Course: Lab Safety > Section: Day 3

Based on the section 4.1.2 Acute Toxicity in the book Laboratory Safety for Chemistry Students by Hill and Finster, 2010 by John Wiley and Sons.

Q: Acute toxicants are characterized by what feature?
- Single, relatively high dose
- single, relatively low dose
- long-term exposures of relatively high dose
- long-term exposures of relatively low dose
A: Single, relatively high dose

Q: The most common toxic effect of chemicals is the category of
- allergens
- poisons
- asphyxiants
- irritants
A: irritants

Q: There is often a delay between initial exposure and the response for allergens, but they are considered to be acuter toxicants because
- a high dose is required
- after sensitization has occurred, the reaction is immediate
- they involve the immune system
- all of the above
A: after sensitization has occurred, the reaction is immediate

Q: "Simple asphyxiants"
- are chemically unreactive
- displace oxygen from the air
- can be lighter or heavier than the average molar mass of air
- all of the above
A: all of the above

Q: "Chemical asphyxiants"
- interfere with oxygen uptake through a chemical reaction in the body
- are acturally the same as "somple asphyxiants"
- are usually not gases
- cause the blood to coagulate
A: interfere with oxygen uptake through a chemical reaction in the body

Q: Pulmonary edema
- is the condition of excess fluid in the lungs
- can be caused by nonasphyxiant chemicals that react with lung air sacs
- can occur rapidly or slowly
- all of the above
A: all of the above

Q: teratogens and fetotoxicants
- have immediate and obvious effects whten ingested
- interfere with the genetic process
- can have an effect on a fetus, even though the mother may not know this
- are frequently encountered in introductory chemistry lab
A: can have an effect on a fetus, even though the mother may not know this

Q: Substances that affect the central nervous system are called
- hepatotoxicants
- neurotoxins
- nephrotoxicants
- teratogens
A: neurotoxins

Q: What compounds often used as pesticides are also neurotoxins?
- cholinesterases
- nephrotoxicants
- organophosphates
- tetratogens
A: organophosphates
