For a preschooler (ages 3 to 5), which apical pulse rate is outside the expected reference range and requires intervention?

Explanation:
The key idea here is recognizing what a normal resting apical pulse looks like in a preschooler and what signs tachycardia shows. For children aged 3 to 5, there’s a typical range for resting heart rate; counting the apical pulse for a full minute helps you determine if the rate is within that expected range. When a rate is noticeably higher than the upper end of that range, it’s tachycardia and signals that the child needs to be checked further. In this scenario, the reading that is clearly faster than normal indicates tachycardia and requires assessment and possible intervention. Start by calming the child and rechecking the pulse, then look for contributing factors such as fever, dehydration, pain, anxiety, or signs of respiratory distress. If the fast rate persists or there are signs of poor perfusion or instability, involve a clinician. The other rates fall within the expected range and do not require urgent action.
