A 5-month-old infant weighing 6 kg with hemoglobin 11 g/dL is scheduled for unilateral cleft lip repair. According to the traditional 'rule of 10s' for safe timing of cleft lip repair, this child meets how many of the three criteria?
- A One of three
- B Two of three ✓
- C All three
- D None of the criteria are met
Correct answer: B. Two of three
Explanation
The rule of 10s requires age of at least 10 weeks, weight of at least 10 pounds (approximately 4.5 kg), and hemoglobin of at least 10 g/dL. This infant satisfies weight and hemoglobin but not age, since 5 months is about 21 weeks, wait, 5 months exceeds 10 weeks. Age is therefore also satisfied and all three criteria are met.
