Question

which symptom is a short-term effect of tobacco use?
a buildup of tooth decay
a large mass on a lung lobe
an increase in glucose levels
a decrease in breathing rate

Explanation:

To determine the short - term effect of tobacco use, we analyze each option:

• "A buildup of tooth decay" is a long - term effect as it takes time to develop due to the long - term impact of tobacco on oral health.
• "A large mass on a lung lobe" (likely a tumor) is a long - term consequence of tobacco use, as it develops over years of exposure.
• "An increase in glucose levels" is not a typical short - term effect of tobacco use.
• "A decrease in breathing rate" occurs shortly after tobacco use. Nicotine in tobacco can initially slow down the breathing rate as it affects the nervous system and respiratory control centers in the short term.

Answer:

D. a decrease in breathing rate
