✅ Correct Answer:

📘 Explanation:

• The normal respiratory rate for a healthy adult at rest is 12 to 20 breaths per minute.
• A rate below 12 may indicate bradypnea (slow breathing).
• A rate above 20 may indicate tachypnea (rapid breathing).
• Respiratory rate is a vital sign and helps assess respiratory and overall health.

• D) 30–40: Too high for adults – indicates severe distress or pathology.
