Pesticide Applicator Core Exam — Practice Exam
Hazards and first aid: practice questions
Our Pesticide Applicator Core bank has 21 questions on this topic. Here are 5 of them with answers; the full mock exam draws from every topic, like the real one.
Question 1
What are acute effects of pesticide exposure?
- Effects that appear soon after exposure, usually within 24 hours
- Effects that appear years after many small exposures
- Effects that occur only from fumigants
- Effects only on wildlife, never on people
Show the answer
A. Effects that appear soon after exposure, usually within 24 hours — Delayed effects appear later; chronic effects follow repeated exposure.
Question 2
What does chronic toxicity describe?
- How fast a pesticide kills pests
- Harm from repeated small exposures over a long period
- How long a pesticide lasts on a leaf
- Harm from one large exposure
Show the answer
B. Harm from repeated small exposures over a long period — The signal word reflects only acute toxicity.
Question 3
What two factors together determine the hazard of using a pesticide?
- Color and odor of the product
- Container size and brand
- Toxicity and exposure
- Price and formulation
Show the answer
C. Toxicity and exposure — Hazard = toxicity × exposure; reducing exposure lowers risk.
Question 4
Which insecticide classes inhibit cholinesterase?
- Insect growth regulators and soaps
- Microbial insecticides such as Bt
- Pyrethroids and botanicals
- Organophosphates and carbamates
Show the answer
D. Organophosphates and carbamates — Cholinesterase tests can detect overexposure before symptoms appear.
Question 5
What is the first thing to do for someone with pesticide on their skin?
- Remove contaminated clothing and wash the skin thoroughly with soap and water
- Give the person milk to drink
- Wipe it off with a dry cloth and continue working
- Apply a burn cream and wait
Show the answer
A. Remove contaminated clothing and wash the skin thoroughly with soap and water — Speed matters; the longer it stays, the more is absorbed.
