Which of the following does not describe acute exposure to hazardous materials?

a.
determination of exposure is almost always after the fact.

b.
long time period between exposure to an agent and the onset of symptoms.

c.
short term period between exposure and the onset of symptoms

d.
usually a one time or few times event that is also usually unexpected

The correct answer is option B.

Explanation:

Acute exposure signifies the exposure to toxic influences of hazardous substances in which there is a short time duration between the exposure and the beginning of symptoms. On the other hand, chronic exposure signifies the long term influences of hazardous substances and they are generally of long time duration.  

Thus, the given option B is, therefore, illustrating chronic exposure not acute exposure.  

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
