Which of the following are considered normal values for a person's pulse and blood pressure?

1. 72 beats per minute and 120 over 80mm Hg

2. 100 beats per minute and 140 over 100mm Hg

3. 160 beats per minute and 100 over 70mm Hg

4. 55 beats per minute and 75 over 60mm Hg

The correct answer is: 72 beats per minute and 120 over 80mm Hg

The choice of 72 beats per minute and 120 over 80 mm Hg aligns with established medical standards for normal pulse and blood pressure values. A resting heart rate for adults typically ranges from 60 to 100 beats per minute, with 72 beats per minute falling comfortably within this range. Similarly, a blood pressure reading of 120 over 80 mm Hg is widely considered the benchmark for normal blood pressure, indicating no immediate risk of hypertension or other cardiovascular issues. Conversely, the other options provided do not meet the criteria for normal values. A heart rate of 100 beats per minute is classified as tachycardia, which may signal an underlying health concern if it occurs at rest. The blood pressure value of 140 over 100 mm Hg is indicative of hypertension. A reading of 160 beats per minute represents a significantly elevated heart rate, while a blood pressure of 100 over 70 mm Hg is generally on the lower end, but could be concerning depending on the individual’s overall health and normal baseline. Lastly, a heart rate of 55 beats per minute is bradycardic (lower than normal), which may warrant further investigation, especially if accompanied by symptoms. Thus, the values of 72 beats per minute
