Final answer:
Narcotic analgesic use typically slows down breathing and is the one factor listed that would not increase a person's respiratory rate. The other factors listed – increased metabolism, the use of amphetamines, and a rise in body temperature – all contribute to an increased respiratory rate.
Step-by-step explanation:
The student question is asking about factors that would increase a person's respiratory rate, except one. The respiratory rate can be affected by various stimuli, such as drug use, metabolic changes, and temperature alterations. In this context:
- Narcotic analgesic use typically decreases respiratory rate by depressing the central nervous system.
- Increased metabolism demands more oxygen, thereby increasing the respiratory rate to meet the body's needs.
- Use of amphetamines stimulates the central nervous system and can increase respiratory rate.
- A rise in body temperature usually increases respiratory rate as the body tries to lose heat.
Therefore, the one exception, which does not cause an increase in the respiratory rate, is narcotic analgesic use.
