A 6-year-old child is brought for BP measurement. According to pediatric guidelines, what should be the appropriate cuff bladder width relative to the mid-arm circumference?

Correct option is C

For accurate BP in children, bladder length should cover 75–100% of arm circumference and width at least 40%. Using too small/large cuffs misclassifies BP.
Explanation of options: (a) ✘ 40–50% width is too narrow, giving false high readings. (b) ✘ 50–70% is suboptimal, still underestimates true guideline. (c) ✔ Correct; 75–100% circumference ensures accurate pressure transmission. (d) ✘ Not based on anatomical arm length, but on circumference.
