Ivy Tech CNA Program Exam 2 Practice

Blood pressure has two numbers: systolic pressure (when the heart contracts) and diastolic pressure (when the heart rests). For adults, a typical normal range is about 100/60 to 140/80. This window covers readings that usually indicate good perfusion without excessive arterial resistance, while allowing for normal daily variation due to activity, posture, or individual differences. Readings below 100/60 can cause symptoms like dizziness from too little pressure, and readings above 140/80 are generally flagged for further evaluation for hypertension in basic nursing practice. The range used here balances recognizing normal variability with the need to identify potentially concerning readings. Other options either start too low or go beyond what’s commonly considered normal in this CNA context.
