Certainly! Let's go through the options to determine the correct range for normal respirations at rest.
1. Evaluating the options:
- Option A: 12-20 per minute
- Option B: 5-12 per minute
- Option C: 18-28 per minute
- Option D: 25-35 per minute
2. Assessing each range:
- Option A: 12-20 per minute is commonly accepted as the normal range for a healthy adult's respiratory rate at rest.
- Option B: 5-12 per minute is lower than the normal resting respiratory rate. Generally, a rate that low may indicate bradypnea, which isn't typical for a healthy adult at rest.
- Option C: 18-28 per minute partially overlaps the normal range, but the upper limit is higher than what is commonly classified as normal. It may indicate tachypnea, which can occur during mild exertion or stress.
- Option D: 25-35 per minute is significantly higher, often signifying tachypnea or other respiratory issues. It's not typical for a resting, healthy adult.
3. Conclusion:
- The only option that aligns perfectly with the generally accepted normal respiratory rate for healthy adults at rest is Option A: 12-20 per minute.
Therefore, the correct answer is:
A. 12-20 per minute
