The nurse must check vital signs on a 2-year-old boy who is brought to the clinic for his 24-month checkup. What criteria should the nurse use in determining the appropriate-size blood pressure cuff? (Select all that apply.)
a. The cuff is labeled "toddler."
b. The cuff bladder width is approximately 40% of the circumference of the upper arm.
c. The cuff bladder length covers 80% to 100% of the circumference of the upper arm.
d. The cuff bladder covers 50% to 66% of the length of the upper arm.
ANS: B, C
Research has demonstrated that cuff selection with a bladder width that is 40% of the arm circumference will usually have a bladder length that is 80% to 100% of the upper arm circumference. This size cuff will most accurately reflect measured radial artery pressure. The name of the cuff is a representative size that may not be suitable for any individual child. Choosing a cuff by limb circumference more accurately reflects arterial pressure than choosing a cuff by length.
