The nurse is preparing to assess the blood pressure of a 3-year-old.How should the nurse proceed?

A) Choose the cuff that says "Child" instead of "Infant."
B) Obtain the reading before the child has a chance to "settle down."
C) Use the diaphragm portion of the stethoscope to detect Korotkoff sounds.
D) Explain to the child what the procedure will be.

Preparing the child for the blood pressure cuff's unusual sensation increases cooperation.Most children will understand the analogy of a "tight hug on your arm." Different arm sizes require careful and appropriate cuff size selection.Do not choose a cuff on the basis of the name of the cuff.An "infant" cuff is too small for some infants.Readings are difficult to obtain in restless or anxious infants and children.Allow at least 15 minutes for children to recover from recent activities and become less apprehensive.Korotkoff sounds are difficult to hear in children because of low frequency and amplitude.A pediatric stethoscope bell is often helpful.
