when checking for proper blood pressure cuff size, which guideline is correct? a. the width of the rubber bladder should equal 80% of the arm circumference. b. the standard cuff size is appropriate for all sizes c. the width of the rubber bladder should equal 40% of the arm circumference.



Answer :

C) The width of the rubber bladder should equal to 40 percent  of the arm circumference.

so option C is correct answer of this question.

According to American Heart Association Recommendations (AHA) for Physical Activity in Adults and Kids.

The ideal length and width of a bladder are given below:-

1.The length of the ideal bladder is greater than or equal to 80 percent of the circumference of the arm of the patient .

2.The width of the ideal bladder is  greater than or equal to 40 percent of the circumference of the arm of the patient .

Here we are assuming arm as a cylinder having some radius r . so the arm must have some circumference .

so in the given conditon constraint on width satisfies the given conditon which is the case of 40% of the arm circumference.

and hence according to AHA guidelines only option C is correct.
