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:

1. Analyze "a buildup of tooth decay": Tooth decay from tobacco use is a long - term effect as it occurs over time due to repeated exposure to harmful substances in tobacco affecting oral health.
2. Analyze "a large mass on a lung lobe": A large mass (like a tumor) on a lung lobe is a long - term consequence of tobacco use, often developing after years of smoking due to cellular damage and mutations.
3. Analyze "an increase in glucose levels": Tobacco use can lead to insulin resistance over time, but an immediate increase in glucose levels is not a typical short - term effect of tobacco use.
4. Analyze "a decrease in breathing rate": When a person uses tobacco, the nicotine and other chemicals can initially cause a decrease in breathing rate as the body reacts to the depressant - like effects of some components in tobacco in the short term.

Answer:

D. a decrease in breathing rate
