When a toxicologist is doing an autopsy, which parts of the body will show the MOST evidence of toxic or poisonous metals?
A.
muscles, ligaments, and tendons
B.
hands and feet
C.
ears, eyes, nose, and mouth
D.
liver, brain, kidney, and spleen
D. liver, brain, kidney, and spleen.
The percent saturation of carbon monoxide poisoning is always 34 percent.
A.
True
B.
False
B. False.
The percent saturation of carbon monoxide (CO) poisoning can vary and is determined by measuring the amount of CO bound to hemoglobin in the blood. It can range from less than 10% to near 100%, depending on the level of exposure and the individual's susceptibility.
Oscar was pulled over in his car and given a breathalyzer test. His BAC (blood alcohol content) was 0.07. Is Oscar legally allowed to drive?
A.
Yes, because the legal BAC limit is 0.08.
B.
Yes, because the legal BAC limit is 0.1.
C.
No, because the legal BAC limit is 0.08.
D.
No, because the legal BAC limit is 0.06.
C. No, because the legal BAC limit is 0.08.
In the United States, it is illegal to drive with a BAC of 0.08 or higher. Therefore, Oscar is above the legal limit and should not be driving.
Toxicology is the study of:
A.
medicine.
B.
substances that have an adverse effect on living organisms.
C.
chemical dyes and colorants.
D.
the insects that may be found at crime scenes.
B. substances that have an adverse effect on living organisms.
Toxicology is the study of the adverse effects of chemicals, drugs, and other substances on living organisms. It involves various branches of science, such as pharmacology, biochemistry, and pathology, to understand the mechanisms by which these substances can cause harm. Toxicologists may also study the environmental impact of chemicals and pollutants.
Which of the following statements is true?
A.
Cyanide is a leading cause of accidental poisoning.
B.
Carbon monoxide is a leading cause of accidental poisoning.
C.
Carbon monoxide is a leading cause of intentional poisoning.
D.
Aconite is a leading cause of intentional poisoning.
B. Carbon monoxide is a leading cause of accidental poisoning.
Carbon monoxide (CO) is a colorless, odorless gas that can be produced by incomplete combustion of fossil fuels and other carbon-containing materials. Because it is difficult to detect without specialized equipment, CO poisoning can occur accidentally when people are exposed to high levels of the gas in poorly ventilated areas or from malfunctioning fuel-burning appliances. CO poisoning is a leading cause of accidental poisoning deaths in many countries.
When a toxicologist is performing an autopsy to investigate the presence of toxic or poisonous metals, the parts of the body that will most likely show the highest evidence are the organs involved in the metabolism and excretion of these substances.
Based on the options provided:
A. Muscles, ligaments, and tendons: While toxic metals may accumulate in tissues, they are not the primary sites of metabolism or excretion, so they may not show the most evidence.
B. Hands and feet: Toxic metals are generally not metabolized or excreted through the extremities, so they may not show the most evidence.
C. Ears, eyes, nose, and mouth: These are sensory organs and not typically involved in metabolism or excretion of toxic metals, so they may not show the most evidence.
D. Liver, brain, kidney, and spleen: These organs play significant roles in the metabolism and elimination of various substances, including toxic metals. The liver detoxifies harmful substances, the kidney filters and eliminates waste products, the brain can accumulate toxic metals due to its high blood flow, and the spleen can also accumulate certain metals. Therefore, these organs are most likely to show the highest evidence of toxic or poisonous metals during an autopsy.
Therefore, the correct answer is D. Liver, brain, kidney, and spleen.
