Patient CareQuestion 22 of 100
Which measurement is routinely obtained on a 9-month-old infant but not on an adult?
a.Standing height against a wall-mounted stadiometer
b.Blood pressure using an adult cuff
c.Head circumference measured around the widest part of the skull
d.Waist circumference at the level of the navel
Explanation
Head circumference is measured routinely in children under about 3 years old to monitor brain growth and detect problems such as hydrocephalus or microcephaly. Infants cannot stand for a stadiometer, so recumbent length is used instead. Adult-size cuffs are never appropriate for infants, and waist circumference is an adult screening measure.
