All of the following are true about blood pressure measurement, EXCEPT:
The length and width of the blood pressure cuff bladder should be 80% and 40% of the arm's circumference, respectively. Use of an inappropriately small cuff, resulting in marked overestimation of true blood pressure, or an inappropriately large cuff, resulting in underestimation of true blood pressure. Systolic and diastolic pressures are defined by the first and fifth Korotkoff sounds, respectively. Monckeberg's sclerosis causes pseudohypeension due to vascular stiffening.
