Final answer:
The correct answer is B. 10 seconds, which is the recommended suction time for children when suctioning the airway clear to avoid potential harm while providing effective care.
Step-by-step explanation:
The recommended suction time for children when suctioning the airway clear is B. 10 seconds. It is important to avoid prolonged suctioning as it can lead to hypoxia and potential harm to the delicate tissues in a child's airway.

Normal respiratory rates vary by age, with infants having a respiratory rate between 30 and 60 breaths per minute, which decreases to about 18 to 30 breaths per minute around the age of 10. By adolescence, the rate is closer to that of adults, which is about 12 to 18 breaths per minute, depending on various factors including the person's overall health and level of physical activity.
