What was Pamela Williamson's blood pressure on December 21, 2021?

The correct choice reflects Pamela Williamson's blood pressure of 138/78 on December 21, 2021. Blood pressure readings are typically expressed in two numbers: the systolic pressure (the first number) and the diastolic pressure (the second number).

In this scenario, 138/78 indicates that the systolic pressure, which measures the pressure in the arteries when the heart beats, was 138 mmHg, while the diastolic pressure, which measures the pressure in the arteries when the heart rests between beats, was 78 mmHg. This reading is significant, as it helps assess cardiovascular health and can guide management decisions between normal and elevated blood pressure ranges.

The other options represent different blood pressure readings that do not match the recorded value for that date, demonstrating the importance of accuracy in health documentation and patient records for effective healthcare analysis.
