Answer:
Option D, taking blood pressure
Explanation:
A sphygmomanometer is a blood pressure cuff and a gauge that, upon inflation, can indicate a patient's systolic and diastolic blood pressures.
The systolic blood pressure (SBP) reflects the maximum force of the left ventricle of the heart as it contracts and pushes blood through the aorta and into the peripheral vasculature. In the fraction of blood pressure, it is represented by the numerator.
The diastolic blood pressure (DBP) reflects the force as the heart muscle relaxes and the atria fill the ventricles with blood in preparation for the next contraction phase. In the fraction of blood pressure, it is represented by the denominator.
The expected range of blood pressure is an SBP of ≤120 millimeters of Mercury (mmHg) and a DBP ≤80 mmHg, or a blood pressure of 120/80, and measuring this is possible with a sphygmomanometer.
