Final answer:
The normal heart rate for preschoolers and young elementary-aged children is between 80-120 beats per minute. Variations in HR can indicate health concerns, and this range helps to identify if a child's HR falls within a healthy range for their age.
Step-by-step explanation:
Normal Heart Rate for Preschoolers and Young Elementary Students
The normal heart rate (HR) for preschoolers and young elementary-aged children is typically B) 80-120 beats per minute. This range accounts for the gradual decrease in HR that occurs from infancy, where it can be around 120 bpm, to young adulthood. It's important to note that HRs can vary with several factors, including activity level and overall health. Disorders of the heart can include abnormal heart rates such as bradycardia (resting rate below 60 bpm) or tachycardia (resting rate above 100 bpm). However, these conditions are more pertinent to adults rather than children.
Understanding the normal range for a child's heart rate helps in identifying potential health concerns. For instance, if a child has a heart rate significantly outside the established normal range without any obvious cause like physical activity, it might signal a need for medical evaluation.
