Final answer:
The normal respiratory rate for a 12-year-old and older is 12-20 breaths per minute, aligning with adult breathing patterns.
Step-by-step explanation:
The expected respirations of a 12-year-old and older is 12-20 breaths per minute (b). This is considered a normal respiratory rate that aligns with adult breathing patterns. From birth to adolescence, the normal respiratory rate of a child decreases. Often under non-exertion conditions, the average human respiratory rate is between 12 to 15 breaths per minute. Therefore, the correct answer is option b) 12-20 breaths per minute.
