Question:
Which are causes of cellular injury? (Select all that apply.)
- Antioxidants
- Chemical agents
- Hypoxia
- Mechanical factors
Answer:
- Chemical agents
- Hypoxia
- Mechanical factors
Injury to cells may be caused by chemical agents, hypoxia, free radicals, infectious agents, physical and mechanical factors, immunologic reactions, genetic factors, and nutritional imbalances. Antioxidants block the synthesis of free radicals.Ch02.8

Question:
Which are the most common risks of lead exposure in children? (Select all that apply.)
- Slowed growth
- Psychosis
- Reduced IQ
- Attention-deficit/hyperactivity disorder (ADHD)
Answer:
- Slowed growth
- Reduced IQ
- Attention-deficit/hyperactivity disorder (ADHD)
Children exposed to lead in the home are at increased risk of damage to the brain and nervous system, slowed growth and development, learning and behavior problems, and hearing and speech problems. Specifically, these risks include reduced IQ, ADHD, juvenile delinquency, and criminal behavior. Psychosis is not a common risk of lead exposure in children.Ch02.9
Question:
Which statements are true regarding apoptosis? (Select all that apply.)
- An active process of cellular self-destruction
- A process that deletes cells during embryonic development 2 / 4
- Local cell death after severe and sudden injury
- Causes cell loss in proliferating cell populations
Answer:
- An active process of cellular self-destruction
- A process that deletes cells during embryonic development
- Causes cell loss in proliferating cell populations
Apoptosis is programmed cell death. It is an active process of cellular self- destruction that is implicated in normal embryonic development, as well as in rapidly proliferating cancer cells. Necrosis is accidental cell death that occurs to local cells after a severe and sudden injury.Ch02.10
Question:
Which of the following statements is correct regarding pathologic hyperplasia?
- Produces abnormal proliferation of abnormal cells.
- Is an adaptive mechanism that enables organ regeneration.
- Increases cell size.
- May occur in response to growth factors
Answer:
- May occur in response to growth factors

- protein peroxidation.
- metabolism of exogenous chemicals or drugs.
- spontaneous decay of superoxide.
- vitamins E and C supplements.
Answer:
- metabolism of exogenous chemicals or drugs.
