This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Pediatric vitals
Prompt focus: Which heart rate range is normal for a resting healthy 6 month old infant?
Why the correct answer works
100 to 160 bpm
100 to 160 bpm is normal for a 6 month old.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
Infants under 1 year typically have a resting heart rate of about 100 to 160 bpm. Heart rate decreases with age toward adult norms of 60 to 100 bpm.
Simple analogy
Think of pediatric vitals like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
