Ohio Lead Abatement Worker Exam
Questions and Answers | Latest Update| Pass Guaranteed
1. Which body system is generally considered most sensitive to the effects of lead
exposure in young children?
A. The respiratory system
B. The central nervous system
C. The skeletal system
D. The integumentary system
Answer: B
Rationale: Lead is a neurotoxin, and the developing nervous system of young children
is especially vulnerable. Even low-level exposure can cause learning disabilities,
lowered IQ, and behavioral problems.
2. What is the primary route of lead exposure for abatement workers on the job site?
A. Absorption through intact skin
B. Inhalation of lead dust and fumes
C. Ingestion of contaminated food eaten off-site
D. Exposure through the eyes only
Answer: B
Rationale: Inhalation of airborne lead dust and fumes generated during disturbance
activities (sanding, grinding, heat gun use) is the primary occupational exposure route,
followed by hand-to-mouth ingestion.
3. A worker who eats lunch in a designated clean area without washing hands is at risk
of which exposure route?
, A. Inhalation
B. Ingestion
C. Dermal absorption
D. Injection
Answer: B
Rationale: Lead dust transferred from hands to food or cigarettes and then
swallowed is an ingestion exposure, which is a major pathway when workers fail to
follow hygiene practices.
4. Which of the following is a recognized symptom of acute high-level lead poisoning
in adults?
A. Abdominal (colic) pain
B. Improved appetite
C. Enhanced short-term memory
D. Increased red blood cell production
Answer: A
Rationale: Acute lead poisoning classically causes severe abdominal cramping (lead
colic), along with fatigue, constipation, headache, and anemia due to lead's
interference with heme synthesis.
5. Chronic low-level lead exposure in adults is most closely associated with which
long-term health effect?
A. Improved kidney function
B. Hypertension and kidney damage
C. Enhanced fertility
D. Stronger bones
Answer: B
Rationale: Long-term lead exposure is linked to elevated blood pressure and
progressive kidney damage, along with reproductive harm and peripheral nerve
effects.
6. Why are pregnant workers at special risk from lead exposure?
A. Lead has no effect on the fetus
B. Lead can cross the placenta and harm fetal development
, C. Pregnancy increases the body's ability to excrete lead
D. Lead exposure only affects the mother
Answer: B
Rationale: Lead readily crosses the placental barrier and can cause miscarriage,
premature birth, low birth weight, and developmental effects in the fetus.
7. What blood test is used to monitor a worker's lead exposure over time?
A. Complete lipid panel
B. Blood lead level (BLL) test
C. Blood glucose test
D. Blood alcohol test
Answer: B
Rationale: The blood lead level (BLL) test, usually reported in micrograms per deciliter
(µg/dL), is the standard biological marker used for medical surveillance of lead-
exposed workers.
8. Under OSHA's lead standard (29 CFR 1926.62), medical removal protection is
generally triggered by which finding?
A. A single low blood lead result
B. Blood lead levels reaching the standard's removal threshold on repeated testing
C. A worker's request for a vacation
D. A worker missing a training session
Answer: B
Rationale: OSHA's construction lead standard requires medical removal from lead
exposure when a worker's blood lead level reaches the regulatory trigger level on a
confirmed, repeated basis, with the employer maintaining pay and benefits during
removal.
9. Which organ system stores the majority of lead absorbed by the body over a
lifetime?
A. Muscles
B. Bones and teeth
C. Skin
D. Lungs
, Answer: B
Rationale: Roughly 90% or more of the body's lead burden accumulates in bone and
teeth, where it can remain for years and be released back into the bloodstream
during physiological stress.
10. Children are more vulnerable to lead poisoning than adults primarily because:
A. They absorb a lower percentage of ingested lead
B. Their bodies absorb a higher percentage of ingested lead and their brains are still
developing
C. They never engage in hand-to-mouth behavior
D. Lead cannot cross into a child's bloodstream
Answer: B
Rationale: Children absorb a greater fraction of ingested lead than adults and are
undergoing rapid neurological development, making them far more susceptible to
lasting harm from smaller doses.
11. Which of these is NOT a typical early symptom of lead exposure?
A. Fatigue and irritability
B. Headache
C. Immediate, obvious skin rash
D. Loss of appetite
Answer: C
Rationale: Lead poisoning is often called a 'silent' illness because early symptoms
(fatigue, headache, irritability, appetite loss) are vague and nonspecific; a visible skin
rash is not a characteristic sign of lead exposure.
12. Anemia caused by lead exposure occurs because lead interferes with:
A. Vitamin C absorption
B. Heme (hemoglobin) synthesis
C. Bone calcium storage
D. Insulin production
Answer: B
Rationale: Lead inhibits several enzymes in the heme synthesis pathway, reducing the
production of functional hemoglobin and leading to anemia.
