Which of the following heart rates would be of concern in an otherwise healthy 10-year-old patient?
60 beats per minute
73 beats per minute
100 beats per minute
120 beats per minute
The Correct Answer is A
Rationale:
A. In a healthy 10-year-old, a heart rate of 60 beats per minute at rest is concerning because the normal resting heart rate for this age group ranges from approximately 70–120 bpm. A heart rate below 70 bpm (bradycardia) may indicate an underlying cardiac conduction issue or other pathology, particularly if symptomatic.
B. 73 bpm is within the normal range for a 10-year-old at rest.
C. 100 bpm is normal and can be expected depending on activity, anxiety, or mild stress.
D. 120 bpm is at the upper limit of normal for a 10-year-old and may be appropriate depending on recent activity or emotional state.

C. Uvulitis can be examined carefully; it is not an absolute contraindication.
D. Bacterial tracheitis affects the lower airway and does not specifically contraindicate pharyngeal examination, though caution is advised if airway compromise is present.
